摘要:
In an optical disc molding device, a heating medium from a low-temperature controller is made to flow in temperature controlling flow passages (passages 3a) formed at locations corresponding to boundary parts of two fixed molds 7 mounted parallel to each other on a fixed platen 3 and in temperature controlling flow passages (passages 6a) formed at locations corresponding to boundary parts of two movable molds 8 mounted parallel to each other on a movable platen 6 to supplement heat exchange.

A pump apparatus includes: a first housing member which includes a first drive shaft insertion hole; a second housing member which includes a second drive shaft insertion hole; a pump drive shaft; a first abutment portion and a second abutment portion formed in the second housing member; the first and second drive shaft insertion holes being previously co-processed in a state in which the first and second housing member are relatively positioned by abutments between the first and second positioning protruding portions and the first and second abutment portions, and a joining member joining the first and second housing members in a state in which the first and second housing members are relatively positioned by the abutments of the first and second positioning protruding portions and the first and second abutment portions so as to re-create a relative position between the first and second housing members at the co-processing.

摘要:
A method of manufacturing an optical disc includes molding a first disc substrate by a first mold simultaneously with a second disc substrate by a second mold while controlling the temperature of the first and second molds by passing a temperature-controlling medium through temperature controlling flow passages provided in the vicinity of a boundary between the first and second molds.
