LEADERSHIP IN TECHNOLOGY

Rapid progress is being made in electronic components technologies, with
attention focused on the submicron level. As a customer needs diversify,
Sankyo's new production technologies, based on fine mechanical technology and
flexible, manufacturing systems (FMS), enable the Company to maintain its
position as a market leader.
Major areas of concentration include office automation, audiovisual related
products, home automation and home appliances and factory automation. Particular
emphasis is placed on meeting customer specifications regarding quality, price
and delivery date.
The Company is a world-leading manufacturer of musical movements,
direct-drive spindle motors for floppy-disk drives, stepping motors used in
floppy-disk drives, VCR capstan motors, magnetic card readers used in bank
systems, AC inductor motors for home appliances, defrost controllers for
refrigerators, optical pick-up units for CD-ROMs and magnetic heads for audio
products.
Sankyo is continuing to develop applied technology for magnetic materials,
function-polymer technology, optical devices and semiconductor devices. Sankyo
has the technology to develop and process component materials. For example,
utilizing vacuum evaporation technology we developed the magnetic resistance
element used in the rotary encoder as a thin-membrane magnetic sensor.
Sankyo also develops and markets such materials as rare-earth polymer
magnetics, used in motors; electronic displays, through the application of
function-polymer technology; and ceraphalloy bearings, manufactured from
revolutionary bearing materials. By developing its own materials, Sankyo is able
to respond quickly to customer needs.
FLEXIBLE PRODUCTION
Sankyo constantly raises the level of its production technology and the
quality of its products. The key concept behind Sankyo's production technology
is the Built-Block System (BBS). A production line is usually made up of blocks
tailored to production of specific goods and of blocks that cover widely used,
fundamental movements. Sankyo's BBS adds versatility and flexibility to these
important blocks, significantly delaying obsolescence. Our systems can easily
switch from small-to mass-scale production. The BBS has enabled Sankyo to
produce more sophisticated products at a lower cost than other companies. We are
now manufacturing the majority of our mass-produced products overseas.
Sankyo's accumulated FA technology enables the Company to develop and promote
such products as multiple processing machines, automatic assembly equipment and
industrial robots. As we approach the 21st century, Sankyo, through
its diverse lines ranging from industrial products to household appliances, aims
to increase its contributions to society.
QUALITY FIRST
Sankyo has continued to improve its quality control technology, for which it
won a Deming Prize in 1976, as well as strengthen its expertise in such key
technologies as we continue the Company's established work on optomechatronics
technology. Sankyo also gains considerable benefit from research and development
carried out in cooperation with its close business partner, Nippon Steel
Corporation. Using the new technologies developed with Nippon Steel, Sankyo
creates innovative products for communications, health, office automation and
household-related areas.
MUSICAL
PRODUCTS DIVISION

Sankyo's operations are rooted in the Musical Products Division. The Company
holds the largest share of the world market for musical movements.
The key to Sankyo's dominance of the market is its ability to offer the
world's most reliable musical movements at a highly competitive price. It has
been able to do so by implementing the world's first mass-production methods for
these products. This kind of self-reliance is a cornerstone of Sankyo's
corporate philosophy.
Traditionally, the manufacture of musical movements was a highly
labor-intensive process. Recently however, increasing automation has meant
tremendous leaps in production and assembly capability. By automating nearly all
processes, Sankyo has increased productivity and achieved uniform
quality-critical factors in supporting Sankyo's dominance of the musical
movements industry.
The Company's presence in the industry is not limited to Japan. Sankyo
maintains an international manufacturing presence in Malaysia and Taiwan, and
since January 1995 in Guangzhou, China. We also have a marketing presence in the
U.S., Europe and Hong Kong.
Musical movements-and the music boxes that depend on them-have a 200-year
history. Before the invention of the phonograph in 1877, the only instrument
available that did not require a musician to play it was the music box. They
were difficult to acquire and treasured by the few who could afford them. During
this century, musical movements have changed, partially as a result of the
mass-production technology pursued by Sankyo, and music boxes have become widely
available.
Sankyo has pursued the development of ever-richer sounding music boxes. The
Company's top-of-the-line Orpheus series, marketed since 1985, features two-tune
deluxe 50-note movements. This series has been very well received, particularly
in the collectibles market. Furthermore, after years of R&D, we introduced
an 80-note disc music box in 1995. The disc music box, which allows the listener
to exchange discs and hear any number of tunes, took Europe and the U.S. by
storm in the days before the phonograph rose to prominence. One hundred years
have passed since then, and now the disc music box is making a comeback as
businesses and hobbyists create a new market for its gorgeous sounds.
The advance of production technology has led to a diversification of
function. Sankyo is now aggressively developing new products in a wide range of
fields based on the technologies accumulated through the creation and
improvement of music boxes. Soft-ejecting mechanisms are just one example. New
applications of our Eou's melody integrated circuit units have enabled us to
create special new products where small, thin, lightweight formats are required.
Furthermore, Sankyo is also manufacturing superior 30-note and 50-note movements
for luxury-class music boxes.
Since 1985, the Company's Suwa Plant has been dedicated to producing quality
musical movements. The entire manufacturing process of the plant-from the
requisition of raw materials to product shipment-is integrated and fully
automated. Strict process and quality control management in this plant led to
its winning a Nihon Keizai Shimbun (Japan Economic Journal) national advanced
plant award for excellence in 1987 and a Japan Plant Maintenance Foundation
first class award for excellence in plant maintenance in 1993.
ELECTRONIC COMPONENTS HEADQUARTERS
To strengthen our electronic component businesses, which encompass such
products as DC micromotors, AC servomotors, optical pickups and magnetic heads,
we integrated marketing, development, production and overseas strategies for the
Motors, Devices and Electromagnetic Components Divisions in July 1994. This
headquarters system allows us to combine strong points that were previously
dispersed among these different divisions.
Through this reorganization, the common functions of the three divisions have
been divided into an Operation Planning Division and a Marketing & Sales
Division from the business divisions was particularly helpful in improving
customer service and the collection of market information, while also making it
possible for us to offer products that more closely match customer needs.
Also, by giving the R&D Center the rank of a new business promotion group
within the Electronic Components Headquarters, we created a group with dual
production and sales functions unlike those of any other business division. This
allows us to respond quickly to dizzying changes in market needs.
ELECTRONIC COMPONENTS HEADQUARTERS

R & D CENTER
The R&D Center is a business group that fosters the growth of new
business fields in the Electronic Components Headquarters. The R&D Center
was created in April 1995 through a reorganization of the Motor R&D
Center.
Sankyo has invested long years of R&D into optics, actuators, magnetic
recording and servo technologies, which are considered indispensable in
multimedia.
Using its own technology, Sankyo has developed optic heads, laser scanner
units, aero/fluid-dynamic bearing motors, servomotors and other products that
have won high praise from users.
Aero/fluid-dynamic bearing motors, which are characterized by ultrahigh-speed
and high precision, are used in high resolution polygonal mirror motors and
hard-disk spindle motors. The AC servomotor, which is distinguished by its
compact size and high performance in industrial equipment, including components
for factory automation. Our laser scanner units, which incorporate recent
developments in optical and actuator technologies, answer a broad range of needs
in laser-beam printers, digital copiers and laser fax machines.
Sankyo will continue basic and applied research into materials technology and
high performance devices. While responding quickly to tumultuous changes in our
markets, we will endeavor to make products that give high value for their price
and meet customer needs.

domestically in the Komagane Plant and overseas in Malaysia, China and
Taiwan.
The Company has now expanded its areas of involvement, starting with
audiovisual (AV), office automation (OA) and home electronics and going into
multimedia, measuring, medical and factory automation (FA) equipment. In this
way, it is meeting a variety of needs and making progress in developing core
parts.
To satisfy market demand for multifunction and low-cost products, Sankyo's
electronic component parts are being improved through advanced technological
discoveries and production rationalization. Over the years, the Company has
accumulated and fused its original and essential technologies of precision
processing, electronics and material application. It is promoting its goals of
developing miniaturized, high performance, energy-efficient actuators and
original concept and design composite-use motors and core parts manufactured
in-house.
In the manufacturing field, submicron precision processing,
computer-controlled measuring systems and the Man-Robot-Machine (MRM) system-a
flexible manufacturing system with assembly lines and robots-guarantee stable
supply, high quality and reliability of products and the cost efficiency of
factories.
Sankyo's major achievements are supported by its exacting quality control
management structure that governs development, manufacturing and sales, and by
its strict products reliability testing. In November 1994, Sankyo acquired ISO
9001 certification.

Sankyo's strength is found in its successful efforts to lower costs and to
carry on all stages manufacturing of high-quality products-including production
of magnetic head-cores, assembly, mounting, and inspection-entirely in-house.
The Company is proud of its innovative quality control procedures, which
incorporate its original automatic inspection system. This enables the
production of high-quality products while meeting the requirement to keep costs
down.
CONTROL DEVICES DIVISION
Appliances that have become essential to today's consumers, such as washing
machines, refrigerators, microwave ovens and air conditioners, all utilize time
switches and AC motors. The Control Devices Division focuses on these core
parts-notably micro AC motors-and manufactures stepping motors and other motors
for use in computer peripherals, office equipment and housing equipment.
Sankyo commenced manufacturing time switches in 1959. Advancing technology
led to changes to motive power units, as the Company developed time switches
powered by motors. Today, Sankyo manufactures time switches powered by both
springs and motors.
With the arrival of the office automation era, the monthly production volume
of stepping motors rapidly increased from 100, 000 in 1982 to 50 million in
fiscal 1995. Stepping motors have become essential components of floppy-disk
drives, data cartridge tape drives, printers, facsimile machines, electric
typewriters, household appliances and video cameras. As stepping motor
specifications become increasingly exacting, Sankyo is working to develop and
manufacture stepping motors that meet all customer requirements, particularly
with regard to cost, torque and precision.
