Title: Display device
Inventor: IKEDA MITSUSHI
IPC: H01L29/786
Filed: 1988-08-05
Abstract: PURPOSE:To cut down cost and to reduce wiring resistance and to increase a rate of performation by forming a data line and a drain of a transparent conductor and metallic layers laminated on it and by forming an picture element electrode and a source of a transparent conductor. CONSTITUTION:The data line and the drain of a thin film transistor TFT are formed of the transparent conductor 13 and the metallic layer 16 and 17 laminated on it, and the picture element electrode and the source of the TFT are formed of the transparent conductor 13. The wiring resistance of a data line is reduced without reducing the numerical aperture. I.e., the resistance of the data line and the drain concerning with the propagation of a signal are low because the metallic layers 16 and 17 are laminated on th transparent conductor 13. Besides, since the picture element which acts to display and the source electrode are formed on only the transparent conductor, the rate of perforation of the source part can be increased as a display electrode. Thus, the efficiency of display can be improved and the cost can be cut down.

IPC: G01D9/16
Filed: 1989-07-28
Abstract: PURPOSE:To reduce the movement quantity of a carriage and to prolong the life by performing control so that the carriage moves to a printing position directly from a last printing position. CONSTITUTION:The carriage 4 mounts a printing mechanism which records an analog signal on recording paper and is moved by a carriage moving mechanism in the width direction of the recording paper 14. For example, when an input signal has six channels, the carriage 4 starts at a 0% position in a printing cycle, moves to a position corresponding to the input signal value of a 1st channel to print a dot, then starts at the position after the printing and moves to a printing position of a 2nd channel to print a dot. Similarly, dot printing is carried out up to a 6th channel and the carriage stops at the position when the printing of the 6th channel is completed, and stays until a next printing cycle. In the next printing cycle, the carriage starts at the stop position to print dots of the respective channels. Home position detection is performed after said dot recording is performed, for example, five times to reduce the movement quantity of the carriage greatly.

Title: Brake power holding device
Inventor: SASA HIROTAKA
IPC: B60W10/18
Filed: 1987-08-05
Abstract: PURPOSE:To prevent the erroneous release of brake power by specifying the adjustment position by a brake power release clutch position adjusting element when a neutral switch of OFF and by releasing the brake power when the actual clutch position is on the clutch connection side. CONSTITUTION:It is checked if an electromagnetic check valve 15 for brake- holding is ON or OFF, and if said valve is ON, it is checked from the output of a neutral switch 9 if a gear is at neutral state or not. When the gear is not in neutral state, it is checked if an adjusting switch SW is pressed for the adjustment on the clutch connection side. When the switch SW is pressed, it is checked if the actual clutch position is on the clutch connection side in comparison with the adjusted position or not, and if the actual clutch position is on the clutch connection side, the check valve 15 is deenergized, and the brake power is released. Therefore, even if a brake power releasing clutch position adjusting element is erroneously adjusted, the release of the unnecessary brake power can be prevented.
