Filed: 1994-11-08
Abstract: PURPOSE: To speedily and accurately discriminate a pit region and a groove region by providing a peak hold circuit to which an adjusting circuit is added in place of the conventional sample-and-hold circuit. CONSTITUTION: A peak hold circuit 47 is composed of a hold circuit 55 and the adjusting circuit 56. When an output signal from an adder is inputted to the hold circuit 55, if a control signal CTL from a microcomputer is at a low level while a transistor Tr of the adjusting circuit 56 is in its off-state, a peak value of this output signal is charged in a capacitor C3. This peak value is compared with a reference voltage by a comparator 48, where a discriminating signal as to whether an optical head is positioned in the pit region or the groove region of an optical disk is outputted to the microcomputer. At this time, when in the pit region the charged peak value is higher than the reference voltage, and the discriminating signal of a high level is outputted, and when in the groove region, the discriminating signal of a low level is outputted by the comparator 48 respectively.

Title: Vibration isolating supporting method
Inventor: MIHASHI KUNIHIRO
IPC: F16F1/36
Filed: 1985-12-05
Abstract: PURPOSE:To enable a high accuracy vibration isolating support by supporting a vibrating source by means of a vibration isolating supporting device, and applying a displacement in the direction, in which the displacement due to the vibrating source is compensated, in response to the signal caused by the vibration of the vibrating source so as to absorb the displacement of an elastic body. CONSTITUTION:When a vibrating source 2 vibrates in the direction shown by the arrows A-B, the first elastic body 6 makes displacement via a supporting table 3. In the signals due to this displacement, high frequency components after amplification are cut away, and only extremely low frequency signals are taken out. And by the voltage coming from a servo amplifier 20, a servo valve 15 is driven, and oil pressures are introduced into an upper hollow chamber 12A or a lower hollow chamber 12B so that a piston 11 is slidably moved in the up and down directions. Since the piston 11 moves in the opposite direction to the displacement of the elastic body 6, the displacement of the elastic body 6 is absorbed by the motion of the piston 11, and the distance between the supporting table 3 and an installation base 4 is kept constant, thus the vibration isolation in the supporting part can be achieved.
