Inventor: INUZUKA YASUHISA
IPC: G06K19/077
Filed: 1989-07-25
Abstract: PURPOSE:To enable the utilization as a plurality of IC cards by mounting an IC module and a card main body formed so as to make the IC module detachable. CONSTITUTION:An IC card is constituted of an IC module 10 and a card main body 11 having a cavity part 12, which has a shape and size almost same to those of the IC module 10 and is provided with a surface opening part 13 slightly large than the IC module 10, formed therein. Therefore, by warping the card main body 11 so as to turn the opening part 13 to the outside, the size of the surface opening part 13 can be temporarily made larger than that of the IC module 10. Therefore, by inserting the IC module 10 in the cavity part 12, the IC module 10 can be mounted in the card main body 11. By this method, the IC module 10 can be separated from the card main body 11.

Title: Air intake control device at the time of deceleration
Inventor: MUKAI TAKESHI
IPC: F02D9/02
Filed: 1981-11-30
Abstract: PURPOSE:To reduce HC in exhaust gas while preventing mixed gas from being concentrated by utilizing a sub-air intake passage provided for improving a combustion efficiency at the time of low loading and supplying secondary intake air via said sub-air intake passage into a combustion chamber at the time of deceleration. CONSTITUTION:Low speed fuel is drawn out at the time of the deceleration of an engine because a high negative pressure is produced in a main air intake passage in the downstream of a throttle valve 6, so that mixed gas has a tendency to be concentrated due to the evaporation, etc., of an fuel adhering to the wall. However at this juncture, air flows into a secondary air intake passage 18 since the high negative pressure is transmitted into the diaphragm chamber 22 of a negative pressure control valve 20 from a negative pressure port 24p to open the same valve 20, so that secondary intake air flows from an introducing port 18p into a sub-air intake passage 4. Accordingly, the high negative pressure in the main air intake passage 2 is turned down while leaning of the mixed gas is quickened, so that the exhaust of HC as a harmful component in exhaust gas caused by the concentration of the mixed gas can be reduced.

Abstract: PURPOSE:To recover a molding at low cost by a method wherein a poly- propylene resin molding to which thermosetting resin is applied is disped into pyrolidone liquid to peel the resin off, the resin and the molding are separated from each other by a difference in specific gravity, and the molding is pelletized in an extruder after melting and kneading. CONSTITUTION:A waste material of a polypropylene resin molding to which thermosetting resin is applied is finely ground to make small pieces. The small piece is dipped into pyrolidone liquid. The liquid permeates an interface between a resin layer and a paint film and the paint film is peeled off. Then, the dipped liquid is set, and the resin is separated from the paint film by a difference in specific gravity. The resin is made to float on a surface of the liquid, and the paint film is deposited on a bottom of the liquid. Therefore, the resin molding part and the paint film are thoroughly recovered. Then, the recovered resin is dried after removing the pyrolidone liquid therefrom. After melting and kneading with an extruder, the recovered resin is pelletized or molded to the molding Therefore, the resin will be easily recovered, or the thermosetting resin will be also capable of being recovered as the solid paint film.

Abstract: PURPOSE:To omit a photo engraving process by a method wherein a plasma state is locally formed on the surface of a substrare and a various kinds of films are directly and locally formed on the substrate. CONSTITUTION:After maintaining the pressure of silane in a reaction tank 2 at 1 or more atm., a beam system installed in the reaction tank 2 is operated to aim energy beams 10, for example, laser beams, at a part 11 on a substrate 1. Then, a silane gas is dissociated by the laser 10 and plasma is also applied to the gas around the part 11 of the substrate 1 to generate silane gas plasma. In this case, the whole energy of the laser beams is not consumed by the dissociation of the silane gas and by plasma, but a part of the laser beams directly irradiates on the part 11 of the substrate 1 to heat the part 11. Thus, the surface temperature at the part 11 of the substrate 1 becomes a value sufficient to generate chemical vapor growth reaction by silane plasma at the surface due to heat effect by a susceptor 3 and the heating effect by the laser beams 10. Then, a film 12, for example, an amorphous silicon film or a polycrystalline silicon film, is formed only around the surface of the section 11 of the substrate 1.
