Title: Lead frame and semiconductor device
Inventor: HIRANO TSUGUHIKO
IPC: H01L23/50
Filed: 1989-06-19
Abstract: PURPOSE:To prevent a tab from inducing three-dimensional displacement even if the material high in coefficient of thermal expansion is used by providing it with the first tab lead strong in mechanical strength and the second tab lead weaker in mechanical strength than the first tab lead. CONSTITUTION:The width of the first tab lead 5A is wider than other second tab leads 5B-5D. That is, since the mechanical strength of the first tab lead 5A is set larger than those of other second tab leads 5B-5D, the second tab leads 5B-5D bend or curve and absorb the stress by thermal expansion, and a tab 4 can be controlled for being displaced three-dimensionally. Hereby, the stress due to thermal expansion is released by the tab leads 5B-5D weak in mechanical strength, so the tab 4 can be suppressed for being displaced three dimensionally.

Title: Pneumatic transport device
Inventor: HORIUCHI TERUO
IPC: B65G53/06
Filed: 1986-07-01
Abstract: PURPOSE:To lessen the capacity of a compressor by furnishing a valve in a transport pipe, opening and closing the valve when a pressure tank and the transport pipe are to be emptied, accumulating the compressed air at the time of closing, and exhausting the residual pulverized/granular substance effectively. CONSTITUTION:When a pulverized/granular substance is to be exhausted entirely from a pressure tank 1 and a transport pipe 14, a full exhaust button of a control circuit 43 is pushed to open a solenoid valve 30, and now the compressed air is introduced into the pressure tank 1. Opening and closing of a valve 50 furnished on said transport pipe 14 is repeated by allowing the exciting current to flow intermittently to a solenoid 51 of the valve 50. When the valve 50 is opened, the substance in said pressure tank 1 is exhausted to the transport pipe 14 by the high-pressure compressed air stored while the valve 50 is closed, and thus the substance in the transport pipe 14 is exhausted to a collector tank 17. This enables perfect exhaustion of the pulverized/granular substance without need for introduction of an especially high pressure air into the pressure tank, which should reduce consumption of air to lead to making a compressor with less capacity.

Title: Platelike object retaining device
Inventor: KOYAMA YASUHIRO
IPC: B25J15/00
Filed: 1988-06-24
Abstract: PURPOSE:To enable a platelike object having an arbitrary breadth to be retained by providing a pair of moving plates, to which retaining claw members are fitted respectively, to both side surfaces of the body so as to be capable of being displaced parallel, and providing springs between both moving plates so as to energize them in such a direction as the plates approach each other, and further providing an open/close device to the body. CONSTITUTION:When a cam plate 26 is turned about 90 deg. by a rotary actuator 25, front and rear moving plates 18A, 18B are pushedly opened symmetrically in the front and rear direction so as to be kept apart each other by the rolling contact of cam followers 27A, 27B. When the cam plate 26 is returnedly turned in the initial direction by the actuator 25, the moving plates 18A, 18B gradually close because they are always energized by springs 24 in such a direction as they approach each other. In the meantime, retaining claw parts 21 engage with both long sides of a lead frame 1 so as to nip the frame 1. The change of the length of the lead frame can be carried out by sliding right and left retaining claw members 19A, 20A, and 19B, 20B with regard to the moving plates 18A, 18B.

Title: Nonreciprocal phase shifter
Inventor: TATSUTA MITSUHIRO
IPC: G01C19/64
Filed: 1982-09-06
Abstract: PURPOSE:To obtain nonreciprocal characteristics in the traveling direction of light by using the combination of birefringent crystal and a nonreciprocal polarization plate rotating element which uses Faraday effect. CONSTITUTION:Light polarized linearly at 45 deg. to (x) and (y) axes is incident from the left-hand side to the polarization-plate 45 deg. rotating element 8 which uses Faraday effect to rotate the plane of polarization by 45 deg.. The rotating element 8 is placed in an external magnetic field H and light passed through it has the direction of polarization rotated clockwise until it is parallel to the (x) axis, thereby entering the birefringent crystal 9. When the ordinary light is set in the x-axis direction, the light beam from the element 8 passes through the birefringent crystal 9 as ordinary light to enter a polarization-plane 45 deg. rotating element 8' which uses Faraday effect. This is applied with a magnetic field H' in the opposite direction and the direction of the passing light rotates counterclockwise by 45 deg. to 45 deg. to the (x) and (y) axes, so that the polarization direction of the incident light coincides with that of the projection beam. When light incident from the right-hand side, the rotation direction of the plane of polarization is reverse, so that the polarization direction of the projection light coincides with that of the incident light.
