Title: Target track position retrieving device
Inventor: MIURA YOSHIO
IPC: G11B7/085
Filed: 1991-12-17
Abstract: PURPOSE:To retrieve an objective address in a short time by switching the address signal of a memory to a focus lock signal. CONSTITUTION:When a focus control circuit is turned ON, and the control is normally operated, a focus lock signal is outputted from a focus lock detecting circuit 35, and a focus element driving coil 33 is operated so that the error signal of a differential amplifier 29 can be reduced. When the lock of the focus control is released during a high speed retrieval, the address of a read only memory is switched through an address decode circuit so that the voltage of a D/A converter can be turned to 0. When the focus lock is released, an optical system transferring stand is stopped. A microcomputer 24 turns ON the focus control again in order to operate the focus control, reads a present reproduction number again, presets a difference with a target position, and operates the high speed retrieval. Thus, the objective address can be detected in the short time.

Title: Voltage controlled oscillator
Inventor: YAMAMOTO HIROYUKI
IPC: H03B5/18
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of adjusting the length dimension of an inductance generation conductor at the time of frequency changeover by parallelly connecting a capacitor for resonance to a variable capacitive diode serially connected to the two inductance generation conductors. SOLUTION: The capacitor C8 for the resonance is connected parallelly to the variable capacitive diode VD1. The capacitor C8 for the resonance functions as a coupling capacitor for coupling the variable capacitive diode VD1 and a strip line L1 and also forms the capacitance component of a resonance circuit 12. In this voltage controlled oscillator 10, since the resonance is performed by using the capacitance of the capacitor C8 for the resonance in the resonance circuit 12, by setting the capacitance of the capacitor C8 for the resonance matched with a negative resistance value corresponding to a desired frequency, stable oscillation is performed even in the case of using a relatively high frequency. Thus, the need of adjusting the length dimension of the strip lines L11 and L12 is eliminated.
