    摘要: There is disclosed a draining cannula to be connected with the left atrium which comprises a tip portion (A), a curvature portion (B) connected with said tip portion and a body tubular portion (C) connected with said curvature portion. The length and the outer diameter of said cannula is sufficient for inserting the cannula into the femoral vein and for reaching the tip portion the left atrium passing through the cava, the right atrium and the interatrial septum. The portion (B) is made of a material which is more flexible than that of said portion (C). A resilient spiral thin wire is provided within the thickenss of the wall part defining the lumen of the curvature portion (B). The cannula is used for draining from the left atrium by inserting it into the femoral vein and passing the tip portion (A) of said cannula through the cava, the right atrium and the interatrial septum to reach the left atrium, without thoracotomy.

    摘要: A directional control valve for a pneumatic cylinder in which a piston of the cylinder can be lowered and elevated in a high speed with a minimum air consumption and the lowering/rising speed of the piston can be controlled before it reaches the upper/lower end portions to prevent bounding of the piston. The directional control valve includes a first pressure chamber communicating with an air supply, a second pressure chamber communicating with one of cylinder chambers divided by the piston of the cylinder, an exhaust pressure port, a pressure controlling mechanism, a pressure controlling and changing means which forms a pressure controlling chamber and a pressure receiving chamber, a first valve member for communicating the first pressure chamber and the second pressure chamber, a second valve member for communicating the second pressure chamber and an atmospheric pressure chamber, a third valve member for communicating the second pressure chamber and a pressure-receiving member, and a fourth valve member which is communicating with the third valve member, the air supply and a pressure control chamber.

    摘要: A flexible magnetic diskette used for magnetically storing various information which is recorded and read by a magnetic head. The diskette includes a flexible plastic disk sheet uniformly coated with magnetic material and having a mount hole at its center, and a holder for securing the disk sheet over the periphery of the mount hole. The holder is also made of a plastic material for holding the flexible disk sheet over the peripheral portion of the mount hole via a double-sided adhesive ring. A core member is made of a magnetic metal having a high abrasive resistance and rigidly attached to the holder over at least a part of a surface of the holder, with which a drive unit is engaged.

    摘要: In a vehicle key device, when a key is inserted into a lock, the former is magnetically coupled to the latter so that data are transmitted therebetween, and only when the data provided by the lock and key correspond with each other is the driving of the engine permitted. This device positively prevents the driving of a vehicle by an unauthorized person.
