Title: Double face image forming device
Inventor: MIYAKE HIROYUKI
IPC: G03G21/00
Filed: 1983-07-27
Abstract: PURPOSE:To perform the double face electrophotographic copying where failures of resupply are prevented, by stacking up transfer papers, whose one face are already copied onto, while shifting their front ends and supplying again these transfer paper in order from the first transfer paper to copy on area faces. CONSTITUTION:A transfer paper P-1 whose one face is copied onto is fed onto a resupply tray and is fed downward on the tray by an elastic roll until the front end strikes a stopper 50. When a next transfer paper P-2 comes, the preceding transfer paper P-1 is fed by a pair of rolls 51 and 52, and the stopper 50 is displaced upward. Next, the stopper 50 is allowed to fall, and the next transfer paper P-2 strikes the stopper, and simultaneously, a pair of rolls 51 and 52 are stopped. This operation is repeated to pile up transfer papers while shifting their front ends. This pile of transfer papers is held between a large roll and a belt turning body and is carried to a prescribed position. The top transfer paper whose front end is in the frontmost is supplied again by a resupply roll brought into contact with the upper face of the pile. Next, the pile is advanced slightly to supply the next tranfer paper.

Title: Gain variable video amplifier
Inventor: KUSANO SUSUMU
IPC: H03G3/30
Filed: 1991-06-07
Abstract: PURPOSE:To keep a DC component of an output signal constant even when a gain is changed by varying a signal level of an AC component extracted from a video signal so as to vary the gain. CONSTITUTION:A video signal comprising a DC component Vi and an AC component vi is inputted to an input terminal t1 and led to an AC component pickup section 2 and an arithmetic section 3 via a buffer 1. The pickup section 2 extracts the signal component vi and the signal level of the extracted component is varied at an attenuation alpha. The arithmetic section 3 subtracts the AC component of the pickup section 2 from the video signal of the buffer 1 and outputs the result to an amplifier section 4. The amplifier section amplifies an input signal at a fixed amplification factor A and an output of the amplifier section 4 is fed to an output terminal t2. Through the constitution above, the level of the AC component is varied by varying the attenuation alpha and the DC component is made constant thereby without fluctuation.

A carrier or a borrow signal is outputted depending whether the number of coincidence signals are more or less than the discidence signal (5). A set output of an FF7 is inputted to the 1st shift register 8 with this signal and a gate circuit is closed after one second and the input signal to a recorder 11 is lost. The recorder 11 is stopped after further 3 seconds with the output of the 2nd shift register 9. The recorder 11 is started with the borrow signal of the counter 6.

Title: Nickel-boron alloy plated lead frame
Inventor: SOEDA MASUMITSU
IPC: H01G4/228
Filed: 1986-06-11
Abstract: PURPOSE:To contrive improvement in workability of the title lead frame by a method wherein the inner layer of specific hardness and the outer layer of specific thickness are laminated in such a manner that a specific relation is given to the thickness of the two layers. CONSTITUTION:The electrolytic nickel film of the inner layer of the title lead frame is formed in the thickness of Hv 350 or less which is the upper limit of safe workability. Tee nickel-boron alloy plated film of the outer layer is formed in the plating thickness of 0.1 mum or above which is the lowest limit of the plating thickness having oxidization-resisting property. When the thickness of the outer layer is reduced to 1/2 or more of the thickness of the inner layer, the effect of the hard nickel-boron alloy plated film layer is increased, and cracks are generated on the whole film. Therefore, the ratio of said thickness is suppressed to 1/2 or less. The improvement in workability can be achieved by lowering hardness by forming the inner and the outer layers into a laminated film having the above-mentioned conditions.
