Title: Device for moving and controlling optical head
Inventor: ITO KINYA
IPC: G11B7/085
Filed: 1986-06-30
Abstract: PURPOSE:To attain a precise positioning by compensating the omission of a track crossing pulse which may occur when an optical head moves at a high speed to pass through an ID field part in a sector on an optical disk. CONSTITUTION:If no tracking error signal 13 that varies with the movement of the optical head 5 shows up normally, a broken line pulse does not appear either. Consequently if the state is left as it is, a count-down pulse 15 is decremented. Judgement whether the broken line pulse is outputted or not can be made according as a flip flop 22 is set or not. If no, an AND gate 20 serves as selecting the output of a 2nd one-shot circuit 19, and the output pulse is supplied to an OR gate 21. Even if the tracking error signal does not show up normally, the precise track crossing pulse can be supplied to an output line 15 by correcting the system of an integrator 17, a 2nd comparator 18, the 2nd one-shot circuit 19 and the AND gate 20.

SOLUTION: A metal coat 1 is provided in time heat exhausting side face of a solid-state laser crystal 100, whereby an alloy layer 2 is formed between the metal coat 1 and a metal heat sink 101. The alloy layer 2 is formed through such a manner that the metal coat 1 and the metal heat sink 101 arc pressed against each other as heated to form the alloy layer 2 through diffusion bonding. As mentioned above, the metal coat 1 and the metal heat sink 101 are formed nearly into one piece through the intermediary of the alloy layer 2, whereby the integral structure composed of the metal coat 1 and the metal heat sink 101 is set as high in thermal conductivity as metal to reduce a heat exhaust failure caused by imperfect thermal contact.  Moreover, it is preferable that the metal coat 1 is formed of material which is high in thermal conductivity and adhesion to the solid-state laser crystal 100 and comparatively low in fusing point so as to make diffusion bonding take place easily.

Abstract: PURPOSE:To compensate the temperature variation of a ultrasonic transmission/ reception sensitivity by controlling a voltage control oscillating circuit and a receiving circuit in accordance with the resistance value variation of a temperature sensor due to the temperature variation of the used environment of an ultrasonic transmitter- receiver. CONSTITUTION:The used environment temperature of the-ultrasonic transmitter-receiver 1 is detected by a temperature sensor 8 and against the resistance value variation of the temperature sensor 8, the output voltage of a control voltage generator (CVG) 9 is controlled so that the amplification factor of a receiving circuit 5 compensates the temperature dependency of the transmission/reception sensitivity of the ultrasonic transmitter-receiver 1, by which even if the transmission/reception sensitivity has the temperature dependency, the temperature dependency can be compensated in the output of the receiving circuit. Also, by a temperature sensor 6, a CVG 7 and a VCO 2, this sensor is constituted so that an oscillation frequency also has a temperature dependency, therefore, by using both a temperature variation of the oscillation frequency and the temperature variation of an amplification factor of the receiving circuit, the temperature dependency of the ultrasonic transmitter-receiver 1 can be compensated effectively.
