Title: Expanded float for reflecting radar wave and its production
Inventor: MINETOMO MORIO
IPC: A01K75/04
Filed: 1992-07-10
Abstract: PURPOSE:To obtain a practically sufficient expanded float containing aluminum foils for reflecting radar in spite of the expanded float and a method for producing the expanded float. CONSTITUTION:A forming material of an outer shell 1 is applied to the inner surface of a metallic mold and two metallic foils 3 are superposed on the inner side thereof and arranged on two positions to fill an expandable material for the central core. The resultant material is then preexpanded to form a float prototype, which is secondarily expanded and swelled to prescribed dimensions. In this preexpansion, the metallic foils 3 are fixed with the expanded material for the central core flowed into a hole 6 of a fixed piece 5. Since the metallic foils 3 are moved on the surface of the central core 1 while maintaining relative positions of the fixed piece with the swelling by secondary expansion, the four aluminum foils are scattered between the outer shell 1 and the central core 2.

IPC: H01Q19/18
Filed: 1984-09-03
Abstract: PURPOSE:To improve both the cross polarized wave characteristic and the beam shaping by combining beams in a vertical plane by means of an array antenna and combining beams in a horizontal plane by means of a cylindrical mirror face. CONSTITUTION:The array antenna 40 as a radiator consists of a waveguide slot antenna and the main reflection plate consists of a cylindrical mirror face comprising partial cylindrical mirror faces 50, 51, 52, 53. The cylindrical axis of the partial cylindrical mirror faces 50, 51, 52, 53 is arranged in parallel with the X axis and the entire cylindrical mirror face is symmetrical with respect to the XZ plane. The slot of the antenna 40 is excited by a current of a waveguide, the amplitude is adjusted mainly by the dimension s and the relative amplitude phase among slots is adjusted mainly by the dimension L. Thus, no cross polarized component is included basically in the wave source by using an element with excellent cross polarized wave identification as each radiation element and the beam shaping is attained. Thus, the excellent cross polarized wave characteristic is obtained without cancelling the cross polarized wave component included in the wave source.

Abstract: PROBLEM TO BE SOLVED: To exclude an adverse effect of screw clamping on an electronic equipment, by providing a member for transferring heat from a heat absorbing member to a heat dissipating member and an elastic member interposed between the absorbing member and the dissipating member, thereby efficiently cooling a semiconductor element. SOLUTION: A heat conduction member 10 is formed in a U shape by superposing metal foils 10a to 10f each having high thermal conductivity, its part (heat absorbing member) is brought into close contact with a surface of a package of a semiconductor element 2 via a heat conductive adhesive material 11, and an elastic member 12 is arranged in the member 10. Thus, heat generated from the element 2 is efficiently dissipated to a housing 1 via the member 10 having high heat conduction, excellent flexibility and brought into surface contact with the element 2 or the housing under a predetermined pressure. Accordingly, since screw clamping is eliminated so that an unnecessary force is not applied to a connector used in the case of fixing the element 2 to the housing, a fault such as its damage, a contact fault or the like is eliminated.

Title: Constructing method for ocean structure
Inventor: INOUE TAKEHISA
IPC: E02B17/00
Filed: 1981-11-19
Abstract: PURPOSE:To eliminate the need for reinforcing of the bottom of a dock and to enable shortening of a work period, by a method wherein, when a marine structure is constructed, a weight which increases with the progress of a work is supported by buoyancy of a structure body. CONSTITUTION:Blocks 8 are placed on the bottom 7 of a dock, and projections 2 on a marine structure body A are placed on the blocks 8. A lower structure body 13 of the body A is then placed on the projections 2, and the two parts are joined by a welding. A number of watertight sections are formed at the inside of the lower structure body 13, and when water is poured into the dock, the lower structure body 13 can be supported by buoyancy, which results in reducing a load applied to the blocks 8 and the bottom 7. A rest part 12 of the body A is placed on the lower structure body 13 to join together the two parts. When a load applied to the blocks 8 increases, buoyancy produced on the body A is increased by increasing an amount of water poured into the canal. This method is effective in the case of a marine structure having a small bottom area.

Filed: 1982-10-22
Abstract: PURPOSE:To keep off a slip in a V-belt as well as to improve the speed change responsiveness ever so better, by connecting a port, which is supplied with line pressure when a spool in a speed change control valve is displaced beyond the specified value in a direction of enlarging a speed change ratio, to a pressure boosting port of a line pressure relief valve. CONSTITUTION:When stepping on an accelerator pedal so quickly, a speed change controller 300 gives a step motor 110 an opening signal quickly rotates a pinion gear 110a toward the large side of a speed change ratio. A spool 174 in a speed change control valve 106 is temporarily shifted to the left side via a speed change control mechanism 112, and ports 172a and 172b are interconnected with each other in position between lands 174a and 174b whereby line pressure is fed to an oil passage 160. This line pressure acts on a port 146a of the speed change control valve 106 and gives right-handed force to a spool 148 so that the line pressure rises. With a temporary rise in the line pressure, oil is quickly fed to a driven pulley cylinder chamber 56 whereby rapid speed change takes place, thus speed change responsiveness is improved and any possible slips in a V-belt are checked.

Abstract: PURPOSE:To enable to operate without lowering the brightness of a reproduced image on a larger area than the conventional one with a low voltage by providing a plural number of parallel and transparent electrodes in the plane of incidence or the opposite side plane of it for the light to a hologram element. CONSTITUTION:A plural number of electrodes 10 parallel with a plane of the crystal (-110) of Bi12, SiO20 or Bi12GeO20 are formed by a transparent conductor such as In2O3, etc. For this a voltage 11 is applied to generate an electric field in the vertical direction with a plane (110).

Title: Method of controlling power steering unit
Inventor: OKADA KUNIO
IPC: B62D6/02
Filed: 1983-10-03
Abstract: PURPOSE:To make it possible to a constant steering force even on uneven road surfaces, by detecting an averaged load in every predetermined period so that the flow rate of oil in a power steering unit is controlled in accordance with the detected averaged load. CONSTITUTION:Since the level of a vehicle body lowers upon heavy load, a shaft 105 moves downward. Meanwhile no substantial change is appreciated in the position of an axle 101 so that a lever 104 rotates about its connecting point with respect to a link 103, and therefore, the shaft 105 rotates in the direction of the arrow. Accordingly, a cylinder 106 also rotates in the same direction as that of the shaft 105 so that a photo-interrupter 61 is aligned with a notch in the cylinder 106, and therefore, light emitted from the light emitting section of the photo-interrupter 61 becomes unshielded by the peripheral edge of the cylinder 106, and is received by the light receiving section of the photo-interrupter 61 which is therefore energized. Upon running of low load a photo-interrupter 62 is energized, and upon running of intermediate load it is deenergized.
