Title: Revolving member for transmission
Inventor: OOHASHI YASUO
IPC: F16H55/17
Filed: 1979-04-24
Abstract: PURPOSE: To increase working accuracy and reduce the weight by forming integrally the boss part having bearing strength and the rim part having superior rigidity from flat plate material, in the molding of the captioned parts such as pulleys for car.  
     CONSTITUTION: A pulley 1 consists of the cylindrical bearing boss part 2 which is formed integrally from flat plate material, the annular flange part 4 which is bent outward from one end of the boss part 2 and has an annular reinforcing rib 3, and the rim part 6 which crosses at right angles with the outer periphery of the flange part 4 and then is bent and has toothed form 5 on the peripheral surface. Through the process of molding, restricting the variation of the thickness of the plate, the thickness of the bent part of the flange part 4 is formed thicker than the plate thickness of the boss part 5, and the bending rigidity is increased. By reducing the radii r 1  and r 2  of curvature of the toothed angular part, molding is performed so that the edge of the tooth 5a is thicker than the tooth surface 5b and the bottom 5c of tooth is thicker than the edge of tooth 5a, and thus the shape of tooth which has superior accuracy and the large effective length of tooth shape can be obtained.

Title: Magnetic suction chuck
Inventor: NOMURA HIROTOSHI
IPC: B65H3/16
Filed: 1985-03-12
Abstract: PURPOSE:To enable only the uppermost sheet out of laminated magnetic thin sheets to be sucked by configurating a device in such a way that a magnet equiped with both a horizontal suction pad and a presser foot are arranged underneath the main body where they are horizontally separated, and the surface of the pressure foot is set to be somewhat lower than the surface of the magnetic suction pad. CONSTITUTION:A presser foot 4 which is connected with a plunger 7 of a cylinder 6, is normally energized upward. When the main body 2 of a chuck is lowered, the surface of the presser foot 4 comes in contact with the upper surface of a magnetic thin plate 1. The magnetic section force of a magnet 3 is set to be sufficient enough to pick up one sheet of the magnetic thin plate 1 by adjusting the step between the surface of the presser foot 4 and the suction pad of the magnet 3 by means of a minor adjustment device 5. This allows only the uppermost sheet out of laminated magnetic thin plates 1 to be floated and sucked to the magnetic suction pad permitting the thin plate to be brought up as the main body 2 of the chuck is raised. When the plunger 7 is lowered, the presser foot 4 is also lowered allowing the magnetic thin plate to be dropped down.

IPC: G01S7/02
Filed: 1988-03-03
Abstract: PURPOSE:To enable remarkable improvement in data rate, by forming an electron scanning only for an operating area excluding an area for which no searching is required. CONSTITUTION:Electron scanning is possible to the right and left of a normal of a radiation section in the way of directing a beam 5 corresponding to a mechanical rotation of an antenna radiation section 1. Then, a beam 5 is formed at an azimuth advanced only by an angle alpha in the direction of rotation with respect to the normal 3 of the antenna radiation section at a rotating position shown in Fig.(a) by a beam scanning function of the radiation section 1. Subsequently, a beam 5 is formed in a bearing the same as a normal 4 when the antenna radiation section directs to the normal 4 thereof as indicated in Fig.(b) decreasing an angle of advance of the beam 5 with the rotation of an antenna. As the normal 4 of the antenna radiation section passes by the beam, a relative angle of the way of directing the beam 5 is delayed from the normal of the antenna radiation section and then, when the antenna radiation section makes one turn and direct to the normal 3 again as indicated in Fig.(c), a beam 5 is formed in a direction delayed by an angle alpha with respect to the direction of rotation. Thereafter, the beam is subjected to an electron scanning by an angle of 2alpha immediately and then, the operation returns to the state of Fig.(a).
