Title: Substrate-placing member, substrate-carrying device, and optical disk-manufacturing device
Inventor: SEKIYA MASARU
IPC: G11B7/26
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To prevent a substrate from being warped and deflected by equipping a substrate placement part with at least three projecting parts in contact with a substrate and bringing closer each cooling speed of the inner/outer-periphery part of the substrate. SOLUTION: A substrate 301 that is placed by forming at least three projecting parts 306 on the substrate placement surface of a substrate placement part 303 is in contact with only the upper part of each projecting part 306 and a substrate-fixing part 304, thus preventing only the inner-periphery part of the high-temperature substrate 301 being taken out of an injection molding machine from being cooled rapidly. For minimizing the top area of the projecting part 306 and for reducing a contact area, the shape is formed to be hemispherical shape, conical shape, and triangular pyramid shape for point contact, thus reducing the amount of diffusion of the heat of the substrate 301 to a substrate placement member 105.  A polyformaldehyde resin, a fluororesin, a silicon resin, or the like with a smaller thermal conductivity than stainless steel or the like and a sufficiently higher transition point than the temperature of the substrate 301 immediately after formation is used as the material for the projecting part 306 and a substrate-fixing part 304 to prevent heat from being diffused rapidly from the substrate 301.

Title: Battery saving system for radio calling receiver
Inventor: OKAYAMA KOICHIRO
IPC: H04W84/02
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To prolong the life of a battery by turning off a receiving and demodulating circuit at leading specific bits of both of first and second code words when both of the first and second code words are unregistered cap codes at the time of taking frame synchronization. SOLUTION: When both of the first and second code words are unregistered cap codes at the time of taking frame synchronization, a power source control part turns off the power source of the receiving and demodulating circuit at the leading three bits of the first and second code words. When a cap-code unregistered in ID-ROM is sent from a base station, comparison/judgment is made with registered cap-codes from the leading bit and also at the time of judging as its own cap-code, the power source is turned off. When both of the first and second code words are unregistered cap-codes like this, the power source of the receiving and demodulating circuit is turned off at the leading 3 bits both of the first and second code words. Consequently, the time of an RF ON state is reduced compared with a conventional system.
