Title: Optical pick-up of optical disk drive
Inventor: CHUNG CHONG-SAM
IPC: G11B7/13
Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To reduce the number of components and simplify structure by using a holographic lens with a pattern for converting only a first laser beam to parallel light when reproducing two types of optical disks while utilizing laser beams with different wavelengths in an objective lens and a photodiode. SOLUTION: When a low-density optical disk 110 is to be reproduced, laser beam with a first wavelength through a prism 115 is converted into parallel light by an incident holographic lens 117. By forming a number of steps on the inner surface of the projection of a pattern being formed at the holographic lens 117, conversion efficiency to parallel light can be increased. The beam spot size of the first laser beam being formed on the surface of a photodiode 119 that is condensed by a light reception lens 118 is allowed to have nearly the same size as the light spot of the second laser beam. The second laser beam is transmitted through the holographic lens 117 as it is.

Title: Diagnostic method for vibration of rotating body
Inventor: MIZUKAMI HIROSHI
IPC: G01M1/16
Filed: 1988-12-27
Abstract: PURPOSE:To easily diagnose an unbalanced amount and position by detecting a vibration at the optional place of a rotary body in the shaft direction with a vibration measurement sensor. CONSTITUTION:At first, normal vibration data at the point 14 on the rotary shaft 11 are measured by the sensor 15 beforehand when the shaft is normally rotation. If the unbalance is occurred at the position X in the shaft direction for some reason or other during the operation, the vibration for the rotary shaft 11 is increased more than before. Only vibration components due to unbalance are extracted by means of vector-subtracting the normal vibration data from these vibration data. An effect coefficient related to the unbalance is calculated therefrom. When the effecting coefficient is found, a load W is identified. Then, the unbalanced position can be specified in such a manner that the positions and weight of all constituent members of the rotary shaft 11 are stored in advance as the data basis and compared with the effect coefficient, load, and vibration amplitude.
