Title: Composite photoreceptor for electrophotography
Inventor: SATOU TSUTOMU
IPC: G03G15/01
Filed: 1979-12-17
Abstract: PURPOSE: To obtain a photoreceptor which permits two-color copying of good quality from a  multicolor original through one exposure by laminating a photoconductive layer which allows the  transmission of chromatic light and a photoconductive layer which is sensitive to chromatic light  on a conductive substrate by way of a layer which selectively shields chromatic light.   
     CONSTITUTION: A photoreceptor 1 is laminated with the 1st photoconductive layer 12, an intermediate layer 13, and the 2nd photoconductive layer 14 in this order on a conductive substrate  11. The intermediate layer 13 consists of a filter layer essentially composed of dyes and pigments  and a blocking layer 132 without containing dyes and pigments. Primary corona charging of the  same polarity as the polarity (positive) at which the 2nd photoconductive layer 14 shows sensitivity is applied to this photoreceptor 1. Thence, the secondary coroa charging of the polarity (negative) opposite from that of the primary charging is applied thereto to invert the surface potential  to negative, thence the light image of the original 2 is applied to this photoreceptor. The electrostatic latent images having mutually different polarities corresponding to the black and chromatic  parts of the original are formed in the respective photoconductive layers of the photoreceptor 1  and if these are successively developed by, for example, a red toner and a black toner, the two- color copy is obtained.

Filed: 1990-06-25
Abstract: PURPOSE:To exactly execute the error detection of information data at the time of reproduction by calculating and adding an odd number/even number parity of this data in addition of a parity byte by a product code, at the time of recording the information data. CONSTITUTION:At the time of recording information data, to its information data, product code parities C1, C2 and an odd number/even number parity byte 51 are added and recorded. When read-in of the data is executed from a disk device 112, it is instructed to an odd number/even number parity calculating part 109, and an odd number/even number parity based on its reproduced data is calculated. Subsequently, a value of the calculated odd number/even number parity and a value of an odd number/even number parity read out actually from the disk device 112 are compared. When both of them coincide with each other, the reproduced data read out of the disk 112 is decided to be no-error, and sent out to a host computer 101. On the other hand, in the case both the values do not coincide with each other, for instance, it is detected that an error such as a byte shift, etc., is generated, and a prescribed error processing is executed. As a result, an error detection of information data at the time of reproduction is executed exactly.

Title: Imputting circuit for camera
Inventor: SUZUKI SHINICHI
IPC: G03B7/00
Filed: 1984-08-06
Abstract: PURPOSE:To decrease a current flowing through a pull-up resistance R without raising a resistance value by providing an MOS transistor for executing a switching control to a current flowing through said resistance, and setting said transistor intermittently to an on-state by an output of a timing signal generating circuit. CONSTITUTION:When a power supply voltage is also normal, a release inhibiting signal SR outputted from a NOR gate 19 becomes a high level, and pulse signals phi0, phi1 generated from a timing signal generating circuit 18 are outputted from AND gates 171, 172, respectively. Also, an output of an invertor circuit 16 becomes an ''L'' level and an ''H'' level, in a period in which the pulse signal phi0 is in an ''H'' level, and in a period in which said pulse signal is in an ''L'' level, respectively, and an MOS transistor TR is brought to conduction/cut-off control. When a shutter release switch SW is depressed, the MOS transistor Tr becomes a conducting state in a period in which the pulse signal phi0 is in an ''H'' level, therefore, a current IR flows to a ground point from a power source terminal 13. The current IR flowing through a pull-up resistance R flows only in its period, and no current flows in the course of a photographing operation of a camera.
