Citizen watch co., ltd have commercialized radio controlled watches for 12 years and succeeded in the development of the full metal base radio controlled watch which is using cal. H41 movement two years ago. This year, we have also accomplished the development of the micro miniature cal. H33 movement which is available for a full metal base radio controlled watch for women. We will report the two systems which is needed to realize the micro miniature cal. H33 movement at the next section. One is an antenna system and the other is an circuit system including the receiver circuit.

This paper describes a new quartz watch driving system we developed. With this system, the second hand of a wrist watch moves smoothly as if it is sweeping. An intermittent movement of the stepping motor is transferred to a smooth sweeping motion due to the spiral spring and the viscous regulator. This system also allows the continued superiority of quartz watches.

We have developed a very low power consumption lOOnA IC for analog quartz watch, using the current control system. As the reference voltage for the current source, we have used a circuit in which the threshold voltage of the depletion and enhancement MOS transistors and their ratio of conductance coefficient are used. For the current source, we have used the current saturation characteristic of MOS transistor. Further, this IC features excellent electrical characteristics, stable temperature characteristics and high yield, due to the CMOS Al gate process in which thin gate oxide is used.

The"CASIO SUPER CYBER CROSS(JG-200)"is an infrared (IR) communication digital watch for children. In addition to watch, alarm and stopwatch function, it has apparatus for short message, game playable alone or with another watch, and TV remote controller. Its communication distance is within 5 meters and the angle is ±15゜. It also is provided with a removable quaking booster, which operates at alarm time, in game and when recieving data. This paper describes the outline of the spesification, IR communicate protocol, and the major components of the watch.

Most of conventional micro manipulators do not have multi purpose functions, sophisticated motions and powers as human being's hands do, and can do only simple works; stabbing, injection and pipette insertion and translation. The purpose of this study is to develop and to assemble a chopstick-type micro hand with much higher workability and compatibility toa conventional manipulator system applying a commertial video game controller pad which has multi-input gate for the micro manipulators. Our chopstick-type micro manipulator is designed referring to the actions of chopstick. When we use the chopstick, a piece of the chopstick at the side of forefinger moves mainly to manipulate an object. But a piece of chopstick at the side of thumb hardly moves at all and only supports an object. Our new chopstick-type micro manipulator can catch a erlass dummy cell (φ50μm) by two glass needle and top of the single finger micro manipulator can reach exactly to the center of dummy cells.

Micro joining technology is one of most important and fundamental technologies for joining, assembling the electronic devices, parts and equipments in intimate relation with assembling technology. Micro joining processes usually involve several joining processes such as ultra-sonic joining, thermo-compression joining, thermo-sonic joining, micro-soldering and so on. These joining processes are described with joining mechanism, funda-mental or some interesting phenomena and its application on assembling monolithic or hybrid integrated circuit and print circuit board. Furthermore, several assembling processes such as wire bending, TAB, Flip Chip, die bonding are given in relation with joining phenomena. Finally, several important subjects on micro joining in future technology are given with the tend of electronic parts and equipments and assembly technology.

This is a short history of Japanese watch industry after the second world war. In Japan, clock industry started in 1860s, and watch industry began in 1890s. Watch and clock industry developed rapidly, but in 1941 the second world war broke out, so that these industries were stopped for the munition production. Since the war, from 1945, these revived, then high quality and big quantity were required. I try to report of watch industry development, on products research and production technology.
