Title: Optical pickup and optical disk device
Inventor: IIZUKA GENICHI
IPC: G11B7/22
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To prevent transmission of a vibration on a yoke to the whole optical base by fixing the yoke as a driving means to this optical base and performing damping processing in a fixing area of the optical base. SOLUTION: At the time of operating a biaxial actuator 36, force is acted on the yoke 36f in the direction opposite to the drive of a movable part 36c. Consequently, the yoke 36f is vibrated, and although this vibration is transmitted to a glass epoxy substrate 31b, because of the existence of a space underneath, no vibration is transmitted to a sheet metal yoke 31a at all. Consequently, the sheet metal base 31a is never deformed by the vibration of the yoke 36f, and hence the optical pickup 30 is never deteriorated in optical characteristic.

IPC: G01R19/165
Filed: 1983-11-07
Abstract: PURPOSE:To detect power failure quickly and effectively by checking AC voltage rectified directly without being smoothed to detect the time when the voltage drops at the eariest possible time. CONSTITUTION:AC voltage is fed to a power source circuit 14 adapted to concurrently allow the use of an external power source through an terminal 15 as independent power source of individual power failure detection circuits while fed to control blocks 16-1, 16-2... varied in the set comparison voltage or the like by stages without being smoothed via a rectification circuit 1.
