Title: Forgery preventive ink and forgery preventive printed matter
Inventor: KOBAYASHI FUMITO
IPC: G03G9/09
Filed: 1993-10-21
Abstract: PURPOSE:To provide the forgery preventive ink with which the forgery made by utilizing a copying machine is easily identifiable even if color materials having arbitrary color tones are used and the forgery preventive printed matter formed by using this forgery preventive ink. CONSTITUTION:This ink contains the arbitrary chromatic color material (first color material) and the color material (second color material) having high reflectivity of >=30% in a full visible light region. The spectral reflectivity of printed parts is increased by incorporating the second color material into the ink. The reproduction of the specific color components among the chromatic components by a copying machine is then not possible and eventually a discolored copy as compared with the original printed matter is obtd. As a result, the presence or absence of copying is easily identifiable. The presence or absence of copying is more easily identified by a combination of the number of lines of images for printing and a combination of the ink.

Title: Sheet feeder
Inventor: SHIKAME YUJI
IPC: B65H1/12
Filed: 1990-10-24
Abstract: PURPOSE:To attain cost reduction by using a common drive source for a feeding means and a switching means, and providing a clutch means for connecting the feed means to the switching means at the time of normal rotation while moderately connecting them at the time of reverse rotation, between them. CONSTITUTION:A clutch 2 is fitted into a cylindrical part protruding from the center of an input gear 2a while a switching cam 12 is fitted through a clutch spring 2b, and a compressing spring 2c is fitted to the outside, thereby due to the friction between the inside face of the cam 12 and the input gear 2a moderate rotation is transmitted. When a paper feed roller 5 is rotated in the paper feed direction, the input gear 2a is rotated in the direction (b) by means of a coaxial gear 6a. Then the cam 12 is rotated but it abuts on a stopper 14 and slides and stops at the minimum position of a cam lift, and a paper sheets abut on a paper feed roller after a pressing plate is energized by a spring 7b so that paper feed is carried out. At the time of reverse rotation of the paper feed roller 5 the cam 12 is rotated to the maximum lift position and the pressing plate is pressed down, thereby paper feed operation is stopped. It is thus possible to carry out switching with only normal/reverse rotation of one motor so as to attain cost reduction.

Title: Vibration isolator
Inventor: ASADA KATSUMI
IPC: H01L21/30
Filed: 1992-10-02
Abstract: PURPOSE:To improve the effect of suppressing vibration caused by disturbance in a vibration isolator for precision instrument or the like by feeding the detected vibration caused by distrubance back to an actuator, and changing the gain of a position control compensator for feeding the displacement of a vibration isolating table back to the actuator. CONSTITUTION:When disturbing force Fd acts upon a vibration isolating table 1 by the acceleration/deceleration of a stage 2 to generate vibration cuased by disturbance, the vibration of the vibration isolating table 1 is detected by a vibration detecting sensor 5 and fed back to an actuator 4 through a vibration control compensator 6. At this time, the gain of a position control compensator 8 for compensating the output of a displacement sensor 7 to feed it back to the actuator 4 is made high by the output of the vibration detecting sensor 5 so as to enlarge the resilience of a vibration system. When the vibration caused by disturbance is settled, the gain is made small inversely to make the resilience small.

Title: Mounting structure of motor-driven compressor
Inventor: ISHIKAWA HIROSHI
IPC: F16F15/08
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To prevent early fatigue destruction of piping through suppression of transmission of vibration of a motor-driven compressor to a vehicle and suppression of transmission of vehicle vibration to the motor-driven compressor. SOLUTION: A compressor is formed such that the spring constant of a first support member 710 to support a compression mechanism Cp is decreased to a value lower than the spring constant of a second support member 720. Since vibration generated by the compression mechanism Cp is absorbed by a first support member 710, transmission of vibration from a motor-driven compressor 100 to a vehicle. Meanwhile, vehicle vibration is absorbed by the second support member 720 having a spring constant higher than that of the first support member 710. This constitution suppresses transmission of vibration of the motor-driven compressor 100 to a vehicle and prevents early fatigue destruction of piping.
