Title: Controller for power steering
Inventor: MASUKUNI KATSUNORI
IPC: B62D6/02
Filed: 1982-09-13
Abstract: PURPOSE:To prevent a needless high assisting force from being generated and a power transistor from being broken, by reducing the quantity of electric power supplied to a motor when a power relay is failed. CONSTITUTION:When a power relay Ry is failed, supply of an electric current is interrupted, whereby the output of a comparator 25b is lowered, and the output D of a steering timer circuit 25 is made to be ''L''. An input to the power transistor 28a is made to be an output E from an idle duty generating circuit, and the rotating speed of the motor 18 is lowered to the minimum rotating speed. Accordingly, the rotating speed of an oil pump is restricted to be low, generation of a large assisting force is prevented, and danger is prevented. When the relay is not operated, the output of an AND circuit A1 becomes ''H'', thereby turning on a transistor 35 to lower an input to the comparator 25b in the timer circuit 25. Accordingly, load on the power transistor 28a is lowered, and the transistor 28a is prevented from being broken.

Title: Driving of el panel
Inventor: SANO YOSHIO
IPC: G09G3/30
Filed: 1987-06-25
Abstract: PURPOSE: To prevent the generation of a flickering look and the reduction of luminance by deviling scanning electrodes into three or more scanning electrode groups, collectively scanning respective scanning electrodes in each group and applying a specific reflesh pulse to the group during the period of no scanning of other groups. CONSTITUTION: Scanning electrodes are divided into three or more scanning electrode groups, and after applying a scanning pulse w1 to a 1st scanning electrode group, a reflesh pulse R1 is applied to all scanning lines in the 1st group at fixed timing. Other scanning electrode groups are similarly processed. Thereby the phases of a scanning pulse and a reflesh puse are made almost symmetrical in each scanning electrode group, so that the luminance-to-voltage characteristic of partial pixels is not sharply changed by light emittion due to the impression of pulse voltage with extremely non-symmetrical phases. Two light emission chances of a scanning pulse and a reflesh pulse can be secured by the light emission of one pixel in a frame.  Consequently the generation of a sense of a flickering look and the reduction of luminance can be prevented differently from a field inversion driving system.

Title: Amplifier
Inventor: SUGAWARA TSUTOMU
IPC: H03F1/34
Filed: 1977-12-27
Abstract: PURPOSE:To make easy low noise constitution, by keeping the operating point of FET near the saturation drain current at all times, by performing negative feedback the second amplifying stage from the output of the third amplifying stage and by picking up the output of the second amplifying stage at the output terminal. CONSTITUTION:The output of the second amplifying stage 22 is picked up at the output terminal 2 and it is negative-fed back to the input side of the second amplifying stage 22 via the third amplifying stage 23 of low pass type. Thus, the output voltage of the second amplifying stage 22 is almost kept at 0 volt. Accordingly, the voltage dividing this output voltage with the resistors 8 and 14 is almost kept at 0  volt. Since this is negative fed back to the source electrode S of the field effect transistor 5, the gate-to-source voltage VGS is controlled at about 0 volt. As a result,  since the transistor 5 is of depletion type, the drain current, that is the operating  point, can almost be set to the saturation drain current. Accordingly, low noise  configuration can be made easily.
