Abstract: PURPOSE: To adapt the advance speed in rectification state to the condition of a motor, and automatically compensate the output change of the motor by computing the rectification advance velocity to get maximum acceleration, using a logical formula, and by putting the rectification to be added to the motor forward by the predetermined number of times of rectification, using these maximum-value velocities. CONSTITUTION: A timing loop starts at step 300, using a series of computed timing values, corresponding to the acceleration of a motor estimated logically. At step 305, the lamp index is initialized, and the first clock signal is sent to a rectification generator at step 310 to put it forward by one reification state, and also the first timing value is read out at step 315, and it is inspected at step 320, and it stands by at the next step 330. Then, after passage of the timing, a clock signal is produced at step 340, and it is sent to the rectification generator, and also, lamp index is increased at step 360, and the sequence from step 315 to 360 is repeated.

Abstract: PURPOSE:To largely reduce electrode resistance of a signal electrode and a scanning electrode of a liquid crystal indication plate to prevent signal attenuation by a method wherein a metallic film is formed with a narrower line width than that of a conductive film on and under or adjacently to the conductive film along the wiring of a transparent conductive film.

Title: Image forming device
Inventor: TAKEUCHI TATSUO
IPC: G03G21/00
Filed: 1983-04-22
Abstract: PURPOSE:To prevent deterioration of a photosensitive body and an image by coating the surface of the photosensitive body after cleaning with a uniform thin film of silicone oil in order to prevent adhesion of corona products and matters low in resistance. CONSTITUTION:An endless belt type oil-coated member 8 are swingably arranged between a uniform exposure lamp 3 and a primary electrostatic charger 4. An oil feeding member 9 is installed and it can be heated with a heater 10. In forming an image, the member 8 is pressed into contact with a photosensitive body 1 with a special swinging mechanism, and the silicone oil heated at 40 deg.C is spread to a uniform thin layer. As a result, the body 1 is given an effect similar to being uniformly heated with a special heater to about 40 deg.C, and deterioration due to adhesion of corona products is prevented. Since the spread oil layer prevents attachment of low resistance matters, such as water vapor, deterioration of an image due to reduction of resistance can be prevented.

Abstract: PURPOSE: To secure the harmony between the increase in power consumption due to the sub-threshold leakage current and the operating speed of a MOS transistor by controlling the substrate bias of a main circuit by means of a signal which is corresponding to the signal that controls the substrate bias of an oscillation circuit. CONSTITUTION: An oscillation circuit OSC1 that is dependent on the substrate bias and shares the substrate bias and the substrate bias of a main circuit LOG1 is connected to a logic circuit, i.e., the circuit LOG1. An oscillation circuit VCLK1 that is dependent on the operation modes and has its oscillation frequency varying by the operation modes is also connected to the circuit LOG1. Then a substrate bias control circuit CNT1 controls with comparison both circuits OSC1 and VCLK1 based on their oscillation outputs so as to secure the synchronism between these outputs. Thus the substrate bias of the circuit LOG1 is controlled. As a result, the threshold value can be increased for a MOS transistor constructing the circuit LOG1. At the same time, the sub- threshold current is reduced and the power consumption of the circuit LOG1 is also reduced.
