Patent JP-H02213870-A (JP)
Title: Recorder
Inventor: NAKAJIMA TETSUO
IPC: G03G15/00
Filed: 1989-02-15
Abstract: PURPOSE:To miniaturize a recorder to lower its cost and to reduce power consumption by uniformly forming the fine recessed part for maintaining developing ink whose viscosity is improved by the electric field of the electrostatic latent image of a photosensitive layer on the surface of an insulating layer. CONSTITUTION:The photosensitive body 1 has a three-layered constitution such as a transparent conductivity layer 4, the photosensitive layer 5 and the insulating layer 6. The fine recessed part 7 is uniformly formed on the surface of the insulating layer 6. A light generating carrier arises inside the photosensitive layer 5 by projecting light corresponding to an image signal from a light source 2 at the time of recording. Charges for a latent image are formed in response to the polarity of a bias impressed by a bias power source 9 between an ink supplying drum 8 and the transparent conductive layer 4. Then, a developing ink 3 is carried on the insulating layer 7 by the ink supplying drum 8 and held in the recessed part 7. The ink is changed (increased) in viscosity by the electric field of the charge of the latent image to be maintained in the recessed part 7, and transferred and fixed on a recording paper 100 pressed on the insulating layer 6 by a pressing roller 10. Therefore, it is possible to attain a high- definition compact, inexpensive recorder which consumes less power.

Title: Device for detecting conveyance of overlapped sheets
Inventor: OIKAWA MASAHIRO
IPC: H04N1/00
Filed: 1982-03-05
Abstract: PURPOSE:To enable the long-term unmistaken detection of conveyance of overlapped sheets, by providing a light receiver on a sheet passage and retaining the level of that output signal of the light receiver which is generated when there is no sheet facing the receiver and by comparing the level with that of a new output signal to judge whether the overlapped sheets are conveyed. CONSTITUTION:A light emitter 1 and a light receiver 2 are provided so that they face each other across the passage of a sheet 4. The output signal of the light receiver 2 is amplified at 3 and then applied to one input terminal of a comparator 7. The amplified signal L is also applied to a sample hold circuit 5. When the send-out of a signal S2 from a control circuit 8 which follows up the change in the signal L has stopped, the sample hold circuit 5 is caused to retain the level of the signal L applied to the circuit just before the stoppage. The voltage level La retained by the circuit 5 is divided by a dividing resistor circuit 6, the divided voltage output of which is applied as a discrimination level LS2 to the other input terminal of the comparator 7. When the level of the signal L is not higher than the discrimination level LS2, the comparator 7 generates a signal S3 indicating the conveyance of overlapped sheets, so that prescribed measures are taken.

A PID arithmetic part 4 uses the differential absolute value obtained from the part 3 as the gain equivalent value and supplies the set value and the control variable to perform the PID arithmetic of a speed type. Then the part 4 has the output of the manipulated variable.

Filed: 1981-03-12
Abstract: PURPOSE:To raise data transfer efficiency, by raising the driving capacity when output driving is started from a high impedance state, and lowering the driving capacity before returning to the high impedance state. CONSTITUTION:While a buffer state controlling signal Cont is in a ''0'' level, even if a data signal Data and a driving capacity controlling signal Drive have any logical value, all driving transistors TR1, TR2, TR3 and TR4 become nonconductive, an output OUT is in a high impedance state. In this case, the buffer circuit remains separated from the bus line. When the Cont is in a ''1'' level and the Drive is in a ''1'' level, if there is Data, the TR1 and the TR3 are turned off, the TR2 and the TR4 are turned on in parallel, and the OUT becomes ''0''. When the Drive is set to ''0'' before the Cont becomes ''0'', the TR4 is turned off, and the driving capacity is lowered so that other buffer can start its driving.
