Title: Protective relay
Inventor: WATABE TAKESHI
IPC: H02H3/05
Filed: 1988-04-25
Abstract: PURPOSE:To improve the reliability, by arranging a plurality of A/D converters and generating reference voltage through resistors thereby preventing erroneous function or disfunction of a protective relay due to fault of A/D converter or fluctuation of source voltage. CONSTITUTION:Electrical amounts of a system are transformed 1', 2' to produce analog outputs which are converted into DC signals through a DC circuit 3', then the DC signals are fed to A/D converters 4', 4'A. Reference voltage generating means 14, 14A receiving source voltages 13, 13A comprise resistors 15, 16, 17 having resistance ratio of 10:5:15, and +5V is produced at the terminal P5 while 0V reference voltage is produced at the terminal COM. Consequently, a CPU 5' can continue processing with data at normal side even upon malfunction of one A/D converter. In case of abnormal source voltage, it is indicated through an indicating circuit 10' and an auxiliary relay 11', and the abnormality is alarmed through function of an abnormal alarm contact.

Title: Display controller
Inventor: NISHI KAZUHIKO
IPC: G09G5/391
Filed: 1984-05-18
Abstract: PURPOSE:To speed up access to a video RAM(VRAM) and to use a dynamic RAM with a long access time as the VRAM by providing a VRAM interface means. CONSTITUTION:The VRAM interface 16 transfers data between a video data processing circuit 10 and the VRAM2. In this case, when a VRAM access request signal RQ is supplied from the circuit 10, the interface 16 outputs a row- address strobe signal RAS' unless a high-speed read signal HSR is supplied. Then, only a column-address strobe signal CASO' is outputted. When the signal RQ is supplied while the signal HSR is supplied, signals CAS' and CAS1 are outputted successively after the signal RAS' is outputted. Consequently, the access to the VRAM2 is speeded up and the dynamic RAM with a long access time is usable as the VRAM.

Title: Liquid crystal device
Inventor: YAMAMOTO TAKASHI
IPC: H05B37/02
Filed: 1990-04-16
Abstract: PURPOSE:To enable dimming which generates no flicker even when the driving period of liquid crystal is variable by varying the illumination time of a light source and dimming the light source by a turn-on device which turns on the light source and setting the dimming period in an area wherein the light output of the light source has no pause period. CONSTITUTION:The liquid crystal display device uses the discharge lamp which dims the light source by varying the ON time ratio of chopping control ad its turn-on circuit 12, whose chipping period is set in the area wherein the light output of the discharge lamp 13 has no OFF time. Namely, the dimming period Tch is set to <=3 times as long as the turn-on period Tl. Consequently, the light output of the discharge lamp 13 connected to the turn-on circuit 12 has no pause period. Therefore, the pause period of the light output and the liquid crystal driving period have no interference in principle. Consequently, even when the driving period is variable for the optimum driving of liquid crystal, the dimming becomes possible without generating an unpleasant flicker such as interference between the driving period and the chopping period for the dimming.

Title: Manufacture of armor component for timepiece
Inventor: IWATA YOSHIO
IPC: G04B45/00
Filed: 1990-04-17
Abstract: PURPOSE:To attach compositely decoration in which a desired mirror pattern in a fold ground area can be easily embossed stereographically without impairing a fold by performing cleaning with cloth in which ultra-fine silicon grain is impregnated. CONSTITUTION:A mask 3 formed by using a masking material on the market by a screen printing method. After that, it is recommended that the gold plating layer of a mirror is formed in half round shape since no stereographical feeling by which a gold plating pattern can be obtained is acquired when the gold plating layer of a non-masking part is peeled. However, the fold that is ground is impaired by performing polishing to form the shape. In such a case, it is possible to obtain a stereographic decoration pattern in which the desired mirror pattern is embossed on the ground area of a polishing fold by polishing it with the cloth in which the ultra-fine silicon is impregnated.
