Inventor: TAKAGI NAOYUKI
IPC: G11B7/095
Filed: 1991-12-19
Abstract: PURPOSE:To obtain a regenerative signal without having an error by detecting a difference between the peak time of a signal regenerated corresponding to a mark on the information recording surface of an optical disk and a substantial peak time to be regenerated corresponding to the mark.

Filed: 1991-12-24
Abstract: PURPOSE:To eliminate the lowering of a leg pillar of a chair even in the case of using a base made of a resin by interlocking the inside peripheral surface of a through-hole having a little larger tapered angle than the tapered angle of the inside peripheral surface of a fitting hole, in the lower end of the fitting hole. CONSTITUTION:In the lower end part 7b of the fitting hole 7, a through-hole 8 having the inside peripheral surface 8a of a little larger tapered angle than the tapered angle of the inside peripheral surface 7a of the fitting hole 7 is interlocked. The lower end part peripheral edge 42a of a leg pillar 4 bites into the inside peripheral surface 8a of the through-hole 8, and by being obstructed thereby, the lowering of the leg pillar 4 is prevented surely. Also, the delicate variation of fitting depth of the leg pillar 4 can be absorbed, and a clearance is not generated between the leg pillar 4 made of a metal and the fitting hole 7 of a boss part 1 made of a synthetic resin whose thermal expansion coefficient is different from that of a metal. Therefore, at the time of the utilization, there is not such a fear as the leg pillar 4 is drawn out easily from the fitting hole 7 and a gas spring contained in the leg pillar 4 is damaged, and this chair can be used stably extending over a long period.
