Title: Method for evaluating withstand electrostatic voltage of ic card
Inventor: TASHIMO HIROSATO
IPC: B42D15/10
Filed: 1989-04-06
Abstract: PURPOSE:To accurately execute the withstand electrostatic voltage evaluation of an IC card by forming the 1st and 2nd electrodes coming into contact with both the faces of the IC card and impressing a high voltage to both the electrodes to charge both the faces of the IC card by induction. CONSTITUTION:A high voltage is impressed to almost the whole area of both the faces 74-1, 74-2 of a card base material 74a by the electrodes 72, 73. In a practical marketing field in which both-side charging of the card base material 74a is general, almost the same condition as an electrostatic destruction state to be practically generated can be set up. Since an aperture part 75 separating an external connection terminal 74b and the electrode 73 with a sufficient inter val is formed, the generation of abnormal discharge between the 2nd electrode 73 and the external connection terminal 74b can be prevented and electrical and mechanical interference between a discharge bar 76 and the electrode 73 when the discharge bar 7 is brought into contact with the terminal 74b can be easily suppressed. Consequently, the withstand electrostatic voltage evaluation of the IC card can be accurately executed.

Filed: 1982-05-27
Abstract: PURPOSE:To simplify the construction of a liquid level sensor by bringing a vibrator with a piezo-electric body stuck on a metal elastic sheet into contact with any liquid to make the sensor. CONSTITUTION:A piezo-electric body 8 comprising crystal or the like is stuck on the top of an elastic sheet 2 to form a vibrator 4 comprising the elastic sheet 2 and the piezo-electric body 3.
