Patent JP-S6378219-A (JP)
Title: Coordinate position input device
Inventor: ANPO TAKEO
IPC: G06F3/042
Filed: 1986-09-19
Abstract: PURPOSE:To prevent malfunction by sequentially scanning light-emitting and light-receiving elements on an axis Y after those on an axis X are sequentially scanned. CONSTITUTION:A clock, which sequentially makes light emitting element strings 2X and 2Y emit light, is given to a drive circuit 5 from a controller 6, and the elements sequentially emit light. At that time, the controller 6 simultaneously operates light receiving element strings 3X and 3Y, so that a pair of light receiving elements become operable. A discrimination circuit 4 discriminates whether a signal from the light receiving element is X or Y, and whether an object to be detected 7 lies on a coordinate plane 1, and gives a light detection signal to the controller 6. It sequentially feeds clocks and causes the light emitting elements to emit light sequentially. The controller 6 patrols the X and Y light emitting elements. After the patrol, the coordinate position of the object to be detected is detected. Thus malfunction can be prevented because light from the other light emitting elements does not make incident.

Title: Method for improving frequency aging of saw device
Inventor: HISATAMA TERUMI
IPC: H03H3/08
Filed: 1985-10-08
Abstract: PURPOSE:To obtain a surface acoustic wave (SAW) device having superior aging characteristics by analyzing factors other than frequency aiging due to mechanical distortion applied from the external to the SAW device chip and removing a part of the factor as less as possible. CONSTITUTION:Several SAW resonators are optionally extracted and respective resonators are dipped in 98% phosphoric acid solution for 10sec, 5-6sec and 2-3sec to etch the surfaces of respective Al electrodes. After washing the etched resonators with water, the devices are left as they are under a 50 deg.C accelerating condition for 5,000hr and the change of resonance frequency is checked every passage of time. Consequently, the change of resonace frequency with the passage of time is remarkably reduced in the group etched for about 10sec as compared to the unetched group or the group etched about for 2-3sec. The crystal of an Al coat disappears with the passage of time due to the rearrangement of crystal grains in accordance with a vapor depositing condition and generates the contraction of its volume. Therefore, the surface of the Al coat is etched at the initial stage of the production of a resonator to reduce the distortion of the film surface and accelerate the reduction of stress.

Filed: 1990-08-28
Abstract: PURPOSE:To obtain safeness by providing a body to be supported (hub) with projecting parts and fixing these projecting parts as an interposed state between two substrates adhered with recording/reproducing areas facing to each other so that even when the hub peels from the substrate, the hub does not disengage from the optical disk. CONSTITUTION:After concentrically adhering a body to be supported (hub) 53 to each substrate 52, two substrates 52 are adhered with a spacer 59 interposed. Thereby, the rotating center of the substrate 52 can be easily coincide with the rotating center of a rotating spindle motor for an optical disk 51. Since flanges 57 are interposed by substrates 52, the hub 53 does not disengage from the optical disk 51 even if adhering part between flanges 57 and substrates 52 is peeled. Thereby, such a problem is avoided that only the hub 53 remains on a turn table when the optical disk 51 is unloaded from the turn table which works as the disk supporter of the optical disk device. Thus, damages on the device due to peeling of the hub can be avoided and the device can be used with safety.
