Title: Focusing position controller
Inventor: ONUKI NOBUTAKA
IPC: G11B7/09
Filed: 1985-09-25
Abstract: PURPOSE:To prevent a signal transmitted conventionally from an objective lens driver during track crossing from being caused by keeping the loop amplification factor from not being increased even when a light beam is between tracks. CONSTITUTION:When the light beam is crossing a track and between tracks, that is, on a mirror face, a focus error detection signal with high sensitivity is inputted to an amplifier 4 via a phase compensation amplifier 1. The focus detection signal in this case is detected at a high level signal and a sinusoidal wave signal at each track crossing is produced. The DC component of the signal is cut off by a capacitor 8 and a comparator 11 shuts off the noise component to detect only a high level and its detection output opens a switch 5. Since the loop amplification factor is decreased by the voltage division comprising resistors 2, 3, 6, it is possible to keep a constant loop amplification factor even during the track crossing.

Title: Temperature display device
Inventor: YAMADA HIROSHI
IPC: G01K7/00
Filed: 1990-08-08
Abstract: PURPOSE:To facilitate operation and to decrease the number of parts by lighting indicator lamps in correspondence with the specified temperature ranges, and changing the brightness of each lamp. CONSTITUTION:When temperature rises, the resistance of an NTC-type thermistor 11 of a switch part 10 is lowered. When a specified temperature, e.g. 100 deg.C, is reached, a transistor (Tr) 12 is operated. The current from a power supply VB flows to a ground 31 in a detection control part 30 through an indicating part 20. When the temperature further rises and reaches, e.g. 160 deg.C, the resistance of a PTC-type thermistor 15 in the control part 30 is increased, and a LED 21 is lit. The brightness is gradually increased. When the temperature further rises, a LED 22 is lit in response to 175 deg.C, and a LED 23 is lit in response to 190 deg.C. The brightness of each LED is gradually increased. When the temperature reaches 220 deg.C, the current flowing to the ground 31 is cut off, and the current flows to a buzzer 24 from a TR 25. In this way, the power supply is turned ON/OFF as required. Therefore, the operation is made easy, and the number of parts can be decreased by using the PTC-type thermistor.
