Abstract: The card connector of this invention has an erroneous insertion prevention mechanism that blocks the IC card at a predetermined blocking position when the IC card is wrongly inserted into the connector body. The erroneous insertion prevention mechanism has a blocking member retractably supported on the first side wall and an urging means to normally urge the blocking member to project inwardly from the second side wall. When the IC card is inserted in a correct orientation, the blocking member is guided by the inclined surface of the IC card to be retracted outwardly from the first side wall. When the IC card is inserted in a wrong orientation, the blocking member abuts against the front end of the IC card, blocking the further insertion of the IC card at the blocking position.

Abstract: A parts-mass compressing device includes a base stand having a table structure on which a mass of vertically standing raised workpieces are disposed. A stopper plate is fixed to one end of said table structure and a moving plate is movable toward and away from said stopper plate. Movement of the moving plate toward said stopper plate compresses the mass. A toggle mechanism drives the moving plate and has first and second toggle links which are pivotally connected at their inner ends. The inner ends are connected to a power cylinder.

Abstract: The write protect switch SW comprises a first piece of metal (50) formed from a stationary metal piece and a second piece of metal (40). The touching portion (46) of the second piece of metal (40) that comes in contact with one of the slide positions of the write protect button (3) in the recess (2) is situated generally at the center position between the contact portion (45) and the holding portion (42) of the second piece of metal (40) or on the holding portion (42) side of the center position. This arrangement ensures a reliable, stable separably connecting operation of the two pieces of metal (40, 50) and provides a necessary contact pressure between them so that the position of the write protect button (3) can be detected accurately and reliably.

Abstract: An acoustic wave transmission system comprises an acoustic wave generating metal tubular member for converting information about the bottom of a borehole, which is obtained by a bottom hole sensor, into an acoustic wave. The acoustic wave generating metal tubular member includes a acoustic wave generating mechanism having at least a magnetostrictive oscillator which is mounted in a recess formed in an outer wall of the acoustic wave generating metal tubular member, and on which a compressive load is imposed by means of a pre-load mechanism using a vise. The magnetostrictive oscillator is constructed of a stack of thin plates each made of a metal magnetostrictive material having a property of increasing its dimensions when magnetized, the thin plates being bonded together by a heat-resistant adhesive. The magnetostrictive oscillator can thus have a buckling strength large enough to resist the compressive load imposed thereon by the pre-load mechanism and a stress due to a strain caused in itself.

Abstract: A vibration exciter machine has magneto striction elements (5,6) supported by a driven pile (2), for providing a vibration of up and down direction to the driven pile (2), and a drive circuit (D1) for controlling expansion and contraction movement of the magneto striction elements (5,6) by changing a supply time period of a current supplied to the magneto striction elements (5,6). By controlling of the drive circuit (D1) the supply time period of the current which flows in the magneto striction elements (5,6) is changed to control the expansion and contraction movement of the elements (5,7). Thereby a horizontal vibration component can be eliminated and only vertical vibration component can be transmitted to the driven pile material (2).
