Abstract: PURPOSE:To allow the formation of slit holes having a smooth inside surface and high accuracy by processing the slit holes in a metallic plate by using a comb-shaped electrode for electric discharge machining, then electrolytically polishing the inside surfaces of the slit holes. CONSTITUTION:The slit holes 3 are formed by electric discharge machining using the comb-shaped electrode 1 for electric discharge machining in the thin metallic plate 2 to the size slightly smaller than the final finish size and thereafter, the inside surfaces of the slit holes 3 of the metallic plate 2 are electrolytically polished and smoothed in the electrolyte and are simultaneously finished to the required size.

The generation of such an undercut as in the case of boring of the slit holes 3 of the required size by etching is obviated. The mask for printing having the slit holes 3 which have the smooth inside surfaces and high accuracy is obtd.

IPC: H01J1/30
Filed: 1988-05-10
Abstract: PURPOSE:To stabilize the trajectory of an electron beam so as to make actually possible to display images with high quality by installing an electric voltage regulating means close to an electron discharging device.

Title: Temperature control method for heat roller fixing device
Inventor: KAWABUCHI HIDENORI
IPC: G03G15/20
Filed: 1988-05-10
Abstract: PURPOSE:To obtain uniform fixing performance from right after a warm-up to stability by setting the set temperature of a fixing roller higher right after the warm-up than in stability and lowering the temperature gradually to the temperature in stability. CONSTITUTION:The set temperature T of the fixing roller right after the warm-up is set higher than the set temperature Tc in stability. Consequently, the surface temperature of the fixing roller right after the warm-up is high, so even if the heat of the fixing roller is absorbed by toner, a pressure roller, etc., heat conducted to a form and the toner is equal to that in stability, so the excellent fixing performance is obtained. When the set temperature T of the fixing roller right after the warm-up is varied to the set temperature Tc in stability, the temperature is varied gradually, stepwise, or continuously and then the heat conducted to transfer paper and the toner is nearly constant to cause neither excessive fixation nor deficient fixation. Copy quantities right after the warm-up, in stability, and at an intermediate point are nearly equal.

Title: Stabilizing control of char bed configuration
Inventor: AKEGAWA YOSHIMITSU
IPC: F22B1/20
Filed: 1989-05-02
Abstract: PURPOSE:To attempt to stabilize the char bed configuration by measuring the value of electric current to the motor of a stirrer for an ash mixing tank and changing the air flow rate and the temperature at the outlet of a black liquor heating heater as advance signals of black liquor concentration. CONSTITUTION:Since the electric current signal from an electric current value signal oscillator 2 of the stirrer of an ash mixing tank varies by the concentration of black liquor and it also varies with the level of the tank and black liquor temperature, the tank level is corrected by a multiplier 5 and the black liquor temperature is corrected by a dividing machine 6 to generate a signal proportional to the concentration of the black liquor. A heater 8 adds concentration signal and advance signal for the correction of concentration from a function generator 7 to give a concentration setting signal and send it to a comparator 10. An air flow rate oscillator 9 measures air flow rate for stabilizing the char bed configuration and sends it to the comparator 10. An air flow rate regulator 11 sends a control signal which corrects a deviation value that is made by the comparator 10 to zero to control the air flow rate. On the other hand the set value of a concentration setting signal is sent to a comparator 16 of the outlet temperature control of a heater for heating the black liquor. Actual temperature is detected by a temperature oscillator 15 and goes into the comparator 16 to send the deviation value to a temperature regulator 17. The temperature regulator 17 sends out control signal so as to bring the temperature of the black liquor to the set value.

Title: Controller for electric power economization of electrophotographic copier
Inventor: NAKAYAMA KENICHIROU
IPC: G03G21/20
Filed: 1981-07-20
Abstract: PURPOSE:To reduce the electric power to be supplied to a heat source and a driving power source by half to economize electric power and to display the state of the half economized power and the fully economized power by a display means simultaneously upon lapse of a constant time after the end of copying. CONSTITUTION:Upon ending of copying operation, a copying operation signal (r) goes to an ''L'', and a flip-flop F/F is held reset, the output (e) thereof is an ''L''. Therefore, the output (g) of an OR gate U7 goes to an ''L'' and the presetting of the 1st timer T1 is released, then a timer T1 starts clocking. When the 1st timer T1 clocks a prescribed time, for example, 1min, it times up and the output (h) thereof is turned to an ''H''; at the same time, the 2nd timer T2 starts clocking, thus reducing the supply electric power by half. At the same instant, a transistor Tr1 conducts, and a relay RL1 and a power economization lamp L1 go on, thereby displaying power economization. Further, a start prohibition signal is outputted, so that the subsequent restarting is prohibited and the full power economization is displayed.

Abstract: PROBLEM TO BE SOLVED: To provide an information recording device in which both of the tone recording and the bivalent recording can be carried out, the scanning timing is set securely without lowering the recording quality and no errors are produced on the scanning positions. SOLUTION: Based on a sensing signal Sbd sensed by a BD(beam detector) 24 for setting the scanning timing for scanning on a light-sensitive drum 20, the strength at the time of incidence of laser beam B into the BD 24 is set stronger than the strength in the scanning on the light-sensitive drum 20. The laser beam B is sensed securely by the BD 24 to set the scanning timing, and the strength is weakened when the recording is carried out on the light-sensitive drum 20 to provide the sharp tone recording or the sharp bivalent recording.
