Title: Jump pulse correcting apparatus and spot controller
Inventor: SUZUKI HARUYUKI
IPC: G11B19/02
Filed: 1994-05-17
Abstract: PURPOSE:To ensure a good and stabilized track jump and tracking control performance by correcting the amplitude of a tracking error signal and the fluctuation of an actuator drive system accurately and automatically in a short time. CONSTITUTION:A drive circuit 9 feeds an actuator 3 with a current substantially in proportional to a digital output value from a selector 8 and drives an objective lens 2 in the direction perpendicular to the track. An amplitude detector 11 detects the true peak value of a digital TE signal and delivers a TA signal having TE amplitude to a controller 10. When the selector 8 is operating on the side (a), the actuator 3 is driven according to the TE signal and a light spot follows the track constantly. When the selector 8 is operating on the side (b), the actuator 3 is driven directly by a JP signal. Consequently, the light spot can be shifted between tracks, i.e., a so-called track jump can be realized by outputting a JP signal having an appropriate level at an appropriate timing.

Title: Floor panel for freely accessible floor
Inventor: MATSUTANI HIROSHI
IPC: E04F15/024
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To distribute stress acting on a floor even when a floor panel is partly cut for use, and improve rupture strength by applying the constitution that a reinforcement rib fitted to the lower surface of a floor panel is formed to have an arched shape. SOLUTION: A plurality of arched reinforcement ribs 2 as well as a plurality of ribs of constant height are respectively arrayed on the lower surface of a square panel top board at intervals in such a state as projected, and integrated with the board. Each of the arched reinforcement ribs 2 is made high at a portion 2a near the center thereof, and reduced in height according to an approach to an end 2b, thereby forming each rib 2 to such a shape as connected with a circular arc having a radius between 1400 mm and 1500 mm. As a result, when a floor panel so made is partly cut at a floor corner or the like for use, stress is distributed to the whole of the reinforcement ribs 2 on the lower surface of the floor panel. Thus, a maximum stress value drops, and rupture strength can be improved without any use of a reinforcement material.
