Abstract: A valve gear comprises a valve 1 having a valve element and a valve stem, and an actuator having a driving shaft for operating the valve element of the valve. A connecting portion 7 is provided on either the valve or the actuator. A sleeve having a smooth inner surface is fixedly or rotatably fitted in a bore formed in the connecting portion 7 so as to slidably receive the valve stem and the driving shaft and slidably contact the inner smooth surface of the sleeve with outer surfaces of the valve stem and the driving shaft. The valve stem and the driving shaft inserted into the sleeve through the opposite ends, of the sleeve are provided at their end portions with respective coupling portions, so that the stem and the shaft are able to engage with each other only at the particular one point of relative rotation of the stem and the shaft.

Abstract: A writing implement having a movable attachment body at the end of a connecting member that is fastened to the writing implement. The writing implement is further provided with a fixed attachment body. Either the movable attachment body or the fixed attachment body, or both, are made of magnets so that they are magnetically attached to each other, thus holding the writing implement in, for instance, a pocket.

Abstract: A paper sheet holder is provided and includes a base plate (1), a paper sheet guiding plate (3) made of non-magnetic material, which is arcuate as viewed in a top plan (upper direction), a permanent magnet (4) fixed at a convex side surface of the paper sheet guiding plate, and a movable permanent magnet (5) movably and magnetically attracted by the curved outer wall surface at the concave surface of the paper sheet guiding plate. The guiding plate is fixed in a slanted orientation above the base plate. A paper sheet holder includes a base plate (25), a paper sheet guiding plate (26) made of non-magnetic material, a plurality of permanent magnets (27) embedded in the paper sheet guiding plate while being spaced apart by a predetermined distance in a horizontal direction, and a plurality of movable permanent magnets (30) spaced apart by a predetermined distance in a horizontal direction.

Abstract: A method and apparatus controls the flow rate of a fluid that flows through a fluid path including a resiliently deformable portion.A first roller has a cutout formed thereon on one side thereof, and a retainer is arranged in parallel with the first roller. The resiliently deformable portion of the fluid path is held between the first roller and the retainer. The first roller is rotatably supported by its rotary shaft. The first distance from the rotary shaft to the outer wall of the first roller on the side facing opposite the resiliently deformable portion may be varied in response to the variation in the angle that occurs when the first roller rotates about its rotary shaft.

Abstract: The present invention is concerned with method and apparatus for opening and closing a multi-way valve. The present invention discloses method and apparatus for controlling the flow of fluid into a plurality of fluid distributing pipes, wherein an elastic wall which constitutes a fluid passage is opened and closed in plural positions by the application of an external pressure to provide communication between only predetermined fluid distributing pipes out of plural fluid distributing pipes connected to the fluid passage.
