Title: Tracking error signal detecting method of optical pickup
Inventor: MATSUI TSUTOMU
IPC: G11B7/095
Filed: 1982-05-28
Abstract: PURPOSE:To obtain a tracking signal containing no inclination of a disk, by leading a reflected ray from the disk to a 2-split optical sensor, and subtracting a detected disk inclination signal from the tracking error signal by a push-pull method. CONSTITUTION:A laser beam from a semiconductor laser 1 becomes parallel light by a collimator lens 2, is reflected by a half mirror 20 through a 1/4 wavelength plate and is made incident to a disk 8. Its reflected ray goes backward, is reflected by a polarized beam splitter 3 and is made incident to a 2-split sensor 30, its output is inputted to a subtracter SB1, and a disk inclination signal Ds is obtained. On the other hand, light which transmits the half mirror 20 is focused onto the disk 8 by an objective lens 6. The reflected ray modulated by a train of a pit P is led to a 4-split sensor 11 through a converging lens 10. By its output, a tracking error signal Te is obtained from a subtracter SB. It is possible to obtain a tracking signal Te1 containing no inclination of the disk 8 due to a difference between Te and SB1, by a substracter SB2.

Abstract: PURPOSE:To prevent lead wires of electronic equipment from absorbing and radiating noise by a method wherein a wire binding device is molded of a flexible polymer material. CONSTITUTION:A wire binding device 11 is molded into a ring shape of a flexible synthetic resin dispersed with ferrite powder and consists of a lead wire insert space 11a, a first stopper piece 11b having a number of tooth outside, a first tongue flap 11c which branches from the base of the first stopper piece 11b and extends parallel with the first stopper piece 11b, a second stopper piece 11d having a number of tooth inside, and a second tongue flap 11e which branches from the base of the second stopper piece 11d and extends parallel with the second stopper piece 11d.
