Title: Recording device using photoconductive toner
Inventor: MURATA KIYOMI
IPC: G03G15/16
Filed: 1984-02-09
Abstract: PURPOSE:To improve gradations of an image, prevent fogging, and obtain a sharp image by using an endless base electrode and an endless counter electrode, and providing an exposure part at the base electrode side. CONSTITUTION:Toner scattered uniformly over a conveyance body 1 to form a single layer is charged electrostatically by an electrostatic charge part 5, for example, positively. Light passed through, for example, a light part 8 of a positive original 7 illuminates the electrostatically charged toner at the exposure part 6 on a conveyance body 1. When the conveyance body 1 is in a conductive state during the exposure, the photoconductive toner at the irradiated part 9 is excited to eliminate the electrostatic charge polarity, and toner corresponding to a dark part 10 rotates together with the conveyance body 1 while having the positive polarity. A flying part 11 impresses a voltage with the polarity opposite to the residual charges of the toner to the counter electrode 2 and the toner flies onto the counter electrode 2 to form a positive image. A transfer material 13 is charged electrostatically from its reverse surface to the polarity opposite to the toner electrostatically charged charges at a transfer part 12 by using a corona electrifier 14 to obtain the positive image on the transfer material 13. Thus, the sharp image is obtained.

Title: Gas turbine warming-up drive controlling circuit
Inventor: SUSAO KENICHI
IPC: F02C9/00
Filed: 1979-02-26
Abstract: PURPOSE: To extend the life of a gas turbine longer with lessening influence of thermal stress at the time of ignition by controlling fuel control signals to the gradient of allowable heat in the gas turbine at the time of warming-up drive.  
     CONSTITUTION: When ignition is confirmed by a flame detector, a contact 28FD is closed, a relay 18 is excited, and further excitation covers a temperature gradient function generator 13 and a logic/analog converter 14. Output from the converter 14 passes through a low value priority diode 16 and determines potential of a control bus 17. Output signals from a thermocouple 11 for measuring exhaust temperature are applied to a mv/V amplifier 12, its output signal B and output signal A from the generator 13 are applied to a comparator 15, which are made into output C passing through the diode 16 and applied to the control bus 17. And for example, in case where exhaust temperature in the gas turbine is smaller than the gradient of allowable temperature, the output C takes the maximum value, fuel control signals select output signals from the converter 14 by the diode 16.

Abstract: PURPOSE:To improve yield by making forming other than stepping on one material divided by an imaginary line, and at the same time, making stepping forming on another material near the boundary, and then making remaining stepping and forming other than stepping on both materials and then dividing into two. CONSTITUTION:The material is divided into a material 10 and a material 12 by an imaginary division line 100.

IPC: G11B20/10
Filed: 1984-02-08
Abstract: PURPOSE:To read accurately information even when the duty ratio of a reproduced signal is deviated by restraining the first counting device from transmitting an output pulse to the second counting device until a reproduced digital signal in a reversed state appears at least once after the generation of the output pulse. CONSTITUTION:When the first counting device 12 detects the deviation of a duty ratio and generates an output pulse, the second counting device 13 makes regular counting or backward counting, and the counted value changes. By constituting a closed loop to apply D/A conversion to the counted value by a D/A converter 14 and feedback to threshold value of a waveform shaping device 10, controlling can be made to make the duty ratio correct. The first counting device 12 is so constituted that once generate the output pulse, transmission of subsequent output pulse to the second counting device 13 is restrained until a reproduced digital signal of a reversed state appears at least once. Thus, the occurrence of error in the threshold value due to drop-out is prevented.

Title: Resetting device of microcomputer
Inventor: MAEDA MUNEKAZU
IPC: G06F1/24
Filed: 1984-02-08
Abstract: PURPOSE:To reset a microcomputer securely even in case of an instantaneous power failure by detecting the primary side voltage of a constant voltage element and connecting the output of a voltage detecting means which has hysteresis to a reset terminal. CONSTITUTION:If an instantaneous power failure occurs in a power feeding state, the voltage at the primary side terminal 2b of the constant voltage element 2 drops and when the base voltage of the 1st transistor (TR) Q1 of the voltage detecting means 3 drops below an ON-voltage, the 2nd TRQ2 turns on. Consequently, a capacitor C1 is discharged abruptly through a resistance R6 and the voltage at the reset terminal of the microcomputer 1 drops to a level L. When the voltage of a power source Vc rises again, the 1st TRQ1 turns on and the 2nd TRQ2 turns off. Consequently, when the capacitor C1 is supplied with a constant current and charged a specific time later, the voltage at the reset terminal RET reaches a level H to perform resetting operation, thereby starting operation normally.
