Title: Optical pickup assembly adjustable in inclination
Inventor: KIN SEKICHU
IPC: G11B7/09
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To increase a driving response speed by driving only an objective lens, thereby making it possible to adjust the relative inclination of the objective lens and a disk. SOLUTION: When currents are impressed to tilting coils 71 of an inclination correcting means 70, the directions of the currents flowing to upper and lower parts 71a, 71b are opposite to each other, and since both are positioned within the magnetic fields of different polarities of the two tilting magnets 73a, 73b, the upper and lower parts 71a, 71b come to receive forces upward and downward at the same time. The inclination of the objective lens 65 may be adjusted by regulating the direction and strength of the currents to be impressed on the tilting coils 71. At this time, the inclination of the objective lens 65 is the radial direction of the disk is regulated by impressing the currents, in such a manner that the force acts in the different coils direction of the tilting coils 71 respectively disposed at a pair of the second flanks 63.  Meanwhile, the directions of the current flowing in both side parts 71c, 71d are opposite to each other, and therefore, the forces acting on these parts are offset with each other.

Title: Q-switch laser device
Inventor: WADA HIROSHI
IPC: H01S3/117
Filed: 1986-07-03
Abstract: PURPOSE:To remove the loss of the inside of a laser resonator, and to increase a Q value and enable stable Q-switching pulse oscillation by preventing application to a Q-switched element of an unnecessary wave component generated on stoppage in response to the stoppage of a high-frequency signal. CONSTITUTION:Since the level of a diode control signal 18 is kept at (0) during a time when a high-frequency signal is applied to a transducer 10, the high-frequency signal is blocked on the cathode side of a diode 17, and does not flow in the direction of a dummy load 20 and all of the signal are applied to the transducer 10. When Q-switching pulse oscillation is conducted, when the high-frequency signal is stopped, the diode control signal 18 is brought to positive potential at the same time, control currents flow through a cathode from an anode for the diode 17, and the diode 17 is brought to a conductive state. Accordingly, all of an unnecessary high-frequency component flow through the diode 17, and bypassed to the dummy load 20 side and removed.
