Title: Power supply circuit for ic card
Inventor: YAMAUCHI AKIRA
IPC: G06K17/00
Filed: 1987-10-08
Abstract: PURPOSE:To ensure the supply of a stable power supply voltage to an IC card by controlling the base voltage of a transistor via a current detecting circuit which detects a current proportional to a current supplied to the IC card. CONSTITUTION:The collector current ICC of a transistor TRQ1 is lower than a prescribed level and a current of low level is supplied to the IC card. Thus the divided voltage VQB1 of the power supply voltage VCC is applied to the base of the TRQ1 and the IC card has the power supply voltage of fixed level. In case the current ICC exceeds a prescribed level and an abnormal current tries to flow to the IC card. Thus the collector current ICC' of a TRQ3 is increased and therefore the level of the voltage of a resistance 5 exceeds the base-emitter voltage VBE5 of a TRQ5. Thus the TRQ5 is turned on and a resistance R2 is short-circuited. Then the base voltage VQE1 of the TRQ1 is set at a low level equal to the emitter-collector voltage. Thus the current flowing to the IC card is also reduced.

Abstract: PURPOSE:To surely correct a picture element defect caused by a switching element failure by providing a counter electrode on other part than the part opposed to a connecting part in which an extended and provided end of a signal input terminal of a stand-by switching element and a branch wiring allowed to branch from a signal line are placed adjacently and opposingly in a non-conducting state through an insulating film. CONSTITUTION:When a position in which a picture element defect is generated is conformed, an extended and provided end 8a of a signal input terminal of a stand-by switching element 7, and a branch wiring 8 allowed to branch from a signal line are connected electrically each other by radiating light energy to a connecting part 25 from the outside through a transparency substrate. When this connection is executed by radiating the light energy, a metal 24 for constituting the extended and provided end 8a of the signal input terminal and the branch wiring is melted, a molten metal is mixed into a display medium, and also, when its contact with the opposed substrate side is generated, a picture element defect is generated. However, in this case, since the counter electrode on the opposite substrate is formed in other part than the part opposed to the connecting part 25, even in the case the molten metal, etc., are mixed into the display medium, it does not come into contact with the counter electrode. In such a way, the picture element defect can surely be corrected.

Abstract: PURPOSE:To smoothly finish the outer peripheral surface of a rubber hose and at the same time prevent rubber hose from springing-back by a method wherein the lead-covered rubber hose is primarily vulcanized under the state having plastically deformable heat inertia and, after the peeling-off of lead, cut and bent, secondarily vulcanized under the state that a mandrel is inserted in the hose and finally formed and vulcanized after the curved mandrel is pulled out of the rubber hose. CONSTITUTION:The outer peripheral surface of a straight molded rubber hose 1 is covered by lead for lead covering. The resultant lead-covered rubber hose is primarily vulcanized by inertially heating it to the plastically deformable state. The temperature for inertial heating is plastically deformable state. The temperature for inertial heating is a temperature, which produces the degree of vulcanization of 2.5-10% when converted to the equivalent vulcanization value. After that, the lead 5 is peeled off from the hose. The resultant molded rubber hose 1 is cut to lengths. A cut rubber hose 1 is bent. Further, after a mandrel 6, onto which release liquid is applied, is inserted in the cut rubber hose, the hose is secondarily vulcanized. Finally, the rubber hose is formed and vulcanized after the curved mandrel 6 is pulled out of the rubber hose 1. Consequently, no spring back develops in the rubber hose and, in addition, its surface is finished smoothly.
