Title: Compact disk player device
Inventor: UEHARA MINORU
IPC: G11B7/095
Filed: 1992-08-06
Abstract: PURPOSE:To eatsily and accurately perform the adjustment by detecting the lower envelope of the reflection signal obtained by superposing a sine wave AC voltage on the DC voltage to a control circuit which generates a focus error signal and correcting the voltage in accordance with the level of the lower envelope for focusing. CONSTITUTION:An AC is superposed on a DC of an offset cancel charging voltage current adjusting part 202 by a sine wave AC voltage current generating means 207. The lower envelope of the reflection signal of a compact disk 100 is detected by a lower envelope detecting means 601 and is converted to a sine AC by a converting means 602. The output of the means 602 is integrated by an integrating means 603, and it is discriminated whether the integral value is larger than 0 or not by a discriminating means 604, and the DC to be charged of the adjusting part 202 is so adjusted that the integral value is 0. Thus, each disk to be used is adjusted to an optimum state even after shipping from a factory, and even the secular change is cancelled.

Abstract: PURPOSE:To easily open or close the cover of a manhole by small forces by providing a handle and an eccentric rotator to be turned with the handle for the cover. CONSTITUTION:A cover body 2 fitted in a freely opening and closing manner into a receiving frame 1, a handle 3 to open or close the cover 2 rotationally by pushing the frame 1, and an eccentric rotator 4 to be turned with the handle 3 and to push up the cover 2 on the support of the projection 1a of the frame 1 are provided. The handle 3 is attached to the cover 2 in a freely inserting and drawing manner.
