Patent JP-H06104704-A (JP)
Title: Input circuit for semiconductor integrated circuit device
Inventor: ASAHINA KATSUSHI
IPC: G11C11/409
Filed: 1992-09-18
Abstract: PURPOSE:To provide an input circuit which can work at a high speed against the input signal that has a minute voltage change. CONSTITUTION:The input signal received from an input signal terminal 3 and the reference voltage received from a reference voltage terminal 4 receive the voltage of a fixed level from a level shift circuit LSI and then are outputted. The output signal and voltage are amplified by the 1st and 2nd differential amplifier circuits Dif1 and Dif2 which are cascaded to each other. The difference between these amplified signal and voltage is inputted to a CMOS inverter circuit In1. The circuit In1 outputs a power potential VDD or an earth potential VSS in accordance with the received difference between the amplified and inputted signal and voltage. Thus it is possible to obtain an input circuit which can work at a high speed even to a minute input signal and also to work in a normal way against the fluctuation of the reference voltage.

Patent JP-H0297269-A (JP)
Title: Actuator
Inventor: TSUDA KIICHIRO
IPC: H02K49/10
Filed: 1988-10-03
Abstract: PURPOSE:To obtain an actuator with very little gas exhausting into vacuum, dustrising and heat generation by driving by driving moving pieces sensitive to a permanent magnet equipped at a piston and connected with an object via the permanent magnet by the piston driven through a fluid pressure. CONSTITUTION:The upper piping of an apparatus is connected with a hydraulic power source 9 and the lower piping thereof, with a drain tank with no mark affixed thereto. A piston 2 moves to left in the drawing and comes close to a moving part 3 so that a magnetic force is applied to the part through a cylinder 1 composed of non-magnetic material and the moving part 3 is attracted to the right against a tension spring 6. When a change-over valve 8 is operated and the connection of the piping is reversed to the above, the piston 2 moves to the right and the distance from the moving part 3 widens. Consequently, the influence of the magnetic force weakens and the moving part 3 is returned to the position of a stopper 7 by the force of the tension spring 6. Thus, a constituent member exposed directly to vacuum is merely the cylinder excepting the moving pieces so that the apparatus exhausts little gas into the vacuum with little dustrising and heat generation.

Title: Camera
Inventor: KUBOTA SHIGEO
IPC: H04N5/95
Filed: 1983-12-26
Abstract: PURPOSE:To improve the accuracy of image recording by allowing a camera which uses an optical disk as a medium to make jitter corrections and control the rotation of the optical disk by obtaining a synchronizing signal from the optical disk. CONSTITUTION:The optical disk 3 is provided with an area for obtaining the synchronizing signal and while an image is recorded on the optical disk 3, the synchronizing signal recorded previously on the optical disk 3 is extracted from a regenerative signal. This synchronizing signal is fed back to a motor driver 22 to control the rotation of the optical disk 3. At the same time, a system controller 6 compares the synchronizing signal with the reference clock of a crystal oscillator 23 to detect jitters, and feeds a jitter correcting signal back to a modulator 15 to make jitter corrections by phase modulation. Therefore, an extremely accurate image is recorded even when an impact, etc., is applied.
