Title: Production of substrate for optical recording medium
Inventor: SUZUKI KAZUTOMI
IPC: G11B7/26
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent second stamping so as to decrease defective sectors and to enhance reliability by injecting an ionizing gas at the time of parting a molded substrate by opening molds. SOLUTION: A resin is introduced via a sprue into the cavity 6 interposed between the moving side 1 and stationary side 3 of the molds in the case of the production of the substrate by injection molding or injection compression molding. The ionizing gas is injected from the gas inflow sections disposed on the moving side 1 and the stationary side 3 when the substrate is parted after the molding. The injection of the ionizing gas is executed on at least the recording side of the substrate and more preferably on both sides. The ionizing gas ionizes air or gas, such as nitrogen, by an electric field. As a result, the electrification of the substrate simultaneously with parting of a stamper 7 and the substrate is suppressed and the second stamping of readhesion to the stamper 7 by the electrification is prevented.  As a result, the occurrence of disturbance in pit shapes is prevented and the complete transfer of the pits of the recording surface to the substrate is made possible.

Title: Card reader/writer
Inventor: WATANABE MAKOTO
IPC: G11B19/12
Filed: 1990-03-16
Abstract: PURPOSE:To shorten card processing time by providing a means to decide in a moment whether the reading direction of a card sucked in from an insertion port is correct or not at the vicinity of the insertion port into which the card is to be inserted. CONSTITUTION:When the card 303 is inserted from the insertion port 103 of a card reader/writer 104, an identification sensor 101 identifies an identification mark 301 and the reading direction 302 attached to the card 303 beforehand, and when the reading direction of the card is correct, the card 303 is sucked in as it is, and a usual state is started. If the reading direction is not correct, the card is not sucked in, and the operation of a purport that an insertion direction is wrong is performed. Thus, since it is decided whether the direction of the card is correct or not in a moment simultaneously with the insertion of the card, the processing time of the card can be shortened.

IPC: B29C35/00
Filed: 1991-03-29
Abstract: PURPOSE:To shorten a heat-up time by increasing the rate of temperature rise up to several times as many as a conventional mold temperature regulator. CONSTITUTION:A mold temperature regulator 1 for a high temperature and a mold temperature regulator 2 for a low temperature are provided, and a mold is supplied selectively with heat-exchanging medium discharged from each mold tempoerature regulator 1, 2. Consequently, a transfer valve for selectively connecting the mold temperature regulator 1 for the high temperature and the mold temperature regulator 2 for the low temperature to the mold is installed, and the heat-exchanging medium are discharged alternately from both mold temperature regulators 1, 2, by opening and closing the transfer valve and can be fed to the mold. A heat storage tank 27 is disposed between the mold temperature regulator 1 for the high temperature and the transfer valve, and the heat-exchanging medium at the high temperature is stored in said heat storage tank 27. When the mold is supplied with the heat-exchanging medium at the low temperature and the heat-exchanging medium at the low temperature is changed over to one at the high temperature, one at the high temperature in sufficient quantity is fed from the heat storage tank 27, thus preventing the loewring of the temperature of the heat-exchanging medium.
