Title: System for amplifying sense and rewriting into memory cell
Inventor: MISAIZU TETSUO
IPC: G11C11/409
Filed: 1990-03-30
Abstract: PURPOSE:To reduce the load of a sense amplifier circuit at the time of sensing by controlling the control signal of transfer gates so that it is dropped to a 1/2Vcc level which is the same as a bit line from a power source Vcc level before sense amplification and it is held to the 1/2Vcc level after sensing. CONSTITUTION:At the time of initialization, a signal TG is in the same level as a power source Vcc, and transfer gates Q15 and Q16 are set in an on-state. When one word line WL is selected, a micro signal corresponding to memory cell information is outputted from a memory cell to the bit line. The micro signal is transferred to the input/output terminals D2 and D2A of the sense amplifier circuit through the transfer gates. Then, the signal TG is dropped to the 1/2Vcc level which is the same as the initial level of the bit line from the Vcc level at the time of sensing. The transfer gates continue a cutoff state until one amplified sense amplifier input/output terminal becomes less than 1/2Vcc-VT(VT is the threshold voltage of the transfer gates) since the control signal TG continuously maintains the 1/2Vcc level. Thus, the load of the sense amplifier circuit is reduced.

Title: Color image forming device
Inventor: HANEDA SATORU
IPC: G03G15/16
Filed: 1989-04-03
Abstract: PURPOSE:To start transferring a color image at an optional position in the conveyance direction of a recording medium by varying the operation period of a means which puts the recording medium passing through a transfer part closer to an image formation body with the transfer area conveyance direction of the recording medium. CONSTITUTION:The operation period of the means 28 which puts the recording medium P passing through the transfer part 16 closer to the image formation body 9 is varied by the transfer area conveyance direction of the recording medium P. Namely, while the margin surface part of the image formation body 9 where no toner image is formed ahead of the top end of the color image passes through the transfer part, an extension state-change roller 28 is displaced from an alternate long and two short dashes line to a solid line position, thereby a tension roller 29 is displaced from the alternate long and two short dashes line to the solid line position to bring a transfer conveyance belt 30 into contact with the image formation body 9 and also make a transfer device 16 start operating. Consequently, the color image begins to be transferred at the optional position in the conveyance direction of the recording medium and the color image can be transferred entirely or up to a halfway point.

IPC: H04N5/335
Filed: 1987-04-07
Abstract: PURPOSE:To reduce reflection on a shading layer and to prevent defective signals from being generated, by forming the shading layer of an organic film. CONSTITUTION:A diffusion layer 2 is formed as a photodetector on a Si substrate 1. An insulating film 3, e.g., an oxidizing film is formed on the layer 2 by a vapor growth method or the like so as to isolate the Si substrate from a wiring electrode or a shading electrode. For example, A1 serving as a wiring layer 4 is formed on the film 3 by e.g., a sputtering method. An insulating layer serving as a protective film 5 is formed on the layer 4 by e.g., a vapor growth method. Further an organic film 6 which is characteristic of this invention is formed of, for example, gelatin, polyimide, and the like. Since this shading layer is formed of the organic film, little reflection is performed on a surface of the shading layer and so defective signals due to irregular reflection can be prevented from being generated.

IPC: B41J2/385
Filed: 1989-04-04
Abstract: PURPOSE:To actuate a printing element drive circuit at high speed by providing an external output clock circuit on a last step of a shift register. CONSTITUTION:An output signal CLK1 outputted from a clock buffer 1 is inputted to a shift register 10, and the shift register 10 outputs an output signal CLK3.
