Title: Cylinder device
Inventor: EMA KIYOO
IPC: F16F9/36
Filed: 1988-09-20
Abstract: PURPOSE:To make it possible to reduce the slide resistance in a lateral load condition by disposing a vibrator giving a reverse piezoelectric effect, so that it expands and contracts in the substantially radial direction and makes contact with a piston rod. CONSTITUTION:In a cylinder device, a vibrator 21 giving a reverse piezoelectric effect is disposed in a slide contact part of a rode guide in a cylinder body 10 so that it radially expands and contracts and makes contact with a piston rod 14. When the vibrator 21 is applied with a periodic electric field, it radially expands and contracts so as to vibrate. The vibration thereof is transmitted to the rod guide 13 of the piston rod 14, and accordingly, a part in the vicinity of the guide 13 also vibrates slightly. As a result, the affection by a friction or an adhesion between the rod guide 13 and the piston rod 14 which occurs by a lateral load can be reduced, thereby it is possible to reduce the slide resistance.

Title: Display information processor
Inventor: KURIHARA YOICHIRO
IPC: G09G5/02
Filed: 1987-09-21
Abstract: PURPOSE: To increase a display processing speed at least up to three times and to improve the throughput of a system by reducing the number of bits to be processed by a graphic control device(GC) from three bits to one bit in the case of using a picture so that symbols of different colors are not superposed. CONSTITUTION: A CPU1 stores all plotting instructions in its own working memory e.g. and transfers the stored instructions to the GC 200b. When a plotting instruction is transferred, the GC200b independently sets up a color register 200h1 to blue and is driven so as to plot a LINE1 (blue line). After ending the plotting of the LINE1, the GC200b turns the color of the color register 200h1 from blue to red and is driven so as to plot a LINE2 (red line). Thereafter the operation is continued based upon plotting instructions transferred from the CPU1. Since the plotting operation of the GC200b is consitinued after driving the CPU1 once, the number of bits to be processed by the GC200b can be reduced from three bits to one bit.
