Abstract: PURPOSE:To firmly bond a ceramic-made member and a thermoplastic resin- made member without using adhesives by a method wherein the heated part of the ceramic-made member heated to higher than the softening temperature of the thermoplastic resin-made member is pushed into the latter. CONSTITUTION:The heated part of a ceramic-made member heated to higher than such temperatures as where a thermoplastic resin (e.g., PVC, PS, PP etc.) comes into the softened state, is pushed into the thermoplastic resin-made member. That part of the thermoplastic resin-made member comes into the softened state while being heated by the heated part of the ceramic-made member, where it is fluidized to be expelled out of the invaded area to the surrounding of the heated part having been inserted causing the heated part of the ceramic-made member to further enter into the thermoplastic resin-made member, so that the heated part of the ceramic-made member may be entered into the desired depth under pressure in the given region of the thermoplastic member. Since the thermoplastic member is contracted by an extent larger than the ceramic-made member when cooled, both members are bonded firmly to provide an integral composite part or unit.

Abstract: PURPOSE:To read quickly a data by providing a control section controlling an optical pickup drive section so that the pickup is stopped nearly at the center of a compact disc obtained an arithmetic section. CONSTITUTION:In loading a disc from which a data is desired to be read on a player, the optical pickup drive section 12 is operated by a control section 13 and a TOC of the disc is read by a data read section 11.
