Title: Optical disk device
Inventor: NAKAJIMA JUNSAKU
IPC: G11B7/09
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the tracking servo control is not properly performed in the conventional method such as the phase difference method or push-pull method due to the possibility for generating the polarity inversion of tracking signals according to the deep pit and shallow pit in the case of the phase difference method or push-pull method using the intensity distribution with the diffracted pattern of the reflected light since this diffracted pattern of the reflected light is changed by the polarity inversion of a tangential push- pull signal when the pit depths are different in the optical disk having the pits with different depths. SOLUTION: This problem is solved by providing a means for detecting the pit depth and controlling the output of the tracking servo signal based on a signal showing the pit depth.

IPC: G01N29/00
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To easily detect degradation of metal with high accuracy by use of changes in the propagation characteristic of ultrasonic waves. SOLUTION: The ultrasonic wave propagation characteristic of a specimen when it is new is measured and stored. After thermal aging or the like is applied to the subject of inspection, the ultrasonic wave propagation characteristic of the specimen is measured under the same condition as that for the first measurement, and detection signals obtained by a receiving probe through both measurements are compared so as to detect the phase difference Δt between both detection signals and compute the rate Δt/T of change in the phase difference Δt (i.e., rate of change of sound speed). Degradation of the specimen is detected on the basis of the rate Δt/T of change in the phase difference.
