Title: Individual identifying system
Inventor: MORI SHIGERU
IPC: G06Q40/02
Filed: 1989-03-23
Abstract: PURPOSE:To prevent a third party from decoding a password number by input operation by providing an altering means which alters the figure of a display means, the confirming means of the altered figure, and a panel where the display means is provided at a position more hollow than a front surface. CONSTITUTION:A password number input means, which consists of a display means 8 to display the figure, an altering means 9 to alter the figures of the display means 8, a confirming means 10 to confirm the altered figure, and a panel 11, where the display means 8 is equipped at the position more hollow than the front surface, is provided. Consequently when a card possessing person inputs the password number, since the display means 8 is provided at the position more hollow than the front surface, it cannot be seen by the third party, and the motion of a finger is only the operation of the altering key 9 to alter the figures and the confirming key 10 to confirm the altered figures. Thus the third party cannot decode the password number by the input operation of the password number of the card possessing person.

Title: Semiconductor memory storage
Inventor: IWAMATSU SEIICHI
IPC: H01L23/525
Filed: 1981-05-12
Abstract: PURPOSE:To obtain a read-only memory, which has high reliability and can be written electrically, through a conduction type writing system by disusing fussion type writing. CONSTITUTION:Doped poly Si 13 is formed onto the SiO2 film 12 of an Si substrate 11. Ar ions are injected and amorphous Si 14 is shaped partially, the whole is temporarily changed into a bad conductor, the surface is coated with CVD SiO2 15, and Al wiring 16 is attached. When the layer 14 is conducted and annealed, its resistance lowers, and the amorphous Si does not become reversible reverse bias. Accordingly, information of which an initial high-resistance consition is made ''0'' and a low resistance condition after electric annealing ''1'' can  be written. The information can be written electrically with high reliability  because there happens no incomplete fusing and short circuit of wiring at that  time.

Abstract: PURPOSE:To inform missing of a picture data to a prescribed telephone number destination by reading telephone number information from a destination registration means, closing a line, reading a voice message from a message storage means and sending the message when the picture data stored in a picture memory is missing. CONSTITUTION:If a power failure takes place while a picture data obtained in the memory reception mode is stored in a picture memory 10 and this picture data stored in the picture memory 10 is missing, a data missing sensor 9d of a sensor section 9 detects and informs it to a control section 8.

Title: Manufacture of valve box made of resin
Inventor: KAKEHASHI KOICHIRO
IPC: B29K105/20
Filed: 1986-03-28
Abstract: PURPOSE:To prevent the exfoliation between an elastic sheet and resin by coating the contact part for the resin of the elastic sheet with adhesive before the resin is poured. CONSTITUTION:When an elastic sheet 3 is installed into mold frames 1 and 2, the contact part for the resin 5 of the elastic sheet 3 is coated with an epoxy group adhesive 7. Resin is poured before the adhesive 7 is hardened. Since the adhesion strength between the elastic sheet 3 and the resin 5 is increased by the adhesion force of the adhesive, the exfoliation between the elastic sheet and the resin which is caused by the fact that the operating force for a valve piece acts onto the elastic sheet on closing the valve can be effectively prevented.

Abstract: PURPOSE:To detect the heat temperature of a roller properly by pressing a control element fixedly against the inner peripheral surface of the hollow of a heat roller and conducting the control element electrically to a heat generating conductor embedded in the heat roller. CONSTITUTION:A shield plate 7 is formed nearly in a U shaped; its base end is fixed to the outer wall surface of a fixed piece 61 and the other end is bent toward the heat roller 1 and arranged closely to the roller 1.
