Inventor: NARITA MASAO
IPC: H01Q15/20
Filed: 1985-08-29
Abstract: PURPOSE:To obtain high mirror surface accuracy, by holding a conductive flexible thin film by means of holding wires from both sides. CONSTITUTION:At the time of launching, a hoop composed of long frames 12a and short frames 12b which are couple with each other by means of hinges A 11a and hinges B 11b is folded by each hingle A 11a and hingle B 11b. After arriving at its orbit, each long frame 12a and short frame 12b are expanded by elastic springs, such ass spiral spring, etc., contained in each hingle A 11a and hingle B 11b, and as the frames 11a and 11b are expanded, holding wire fittings 21 and a conductive flexible thin film 20 are expanded. When each hingle A 11a and hingle B 11b respectively reach 180 deg. and 135 deg., the holding wire fittings 21 are stretched with sufficient tension and, at the same time, holding wires 19 fitted to the fittings 21 are also stretched with sufficient tension. When the holding wires 19 are stretched, the conductive flexible thin film 20 fitted to the holding wires 19 so that it can be supported from both sides is stretched under condition where in-plane tension is small and forms a reflector mirror surface.

Title: Actuator
Inventor: OYAMA HITOSHI
IPC: H02N2/00
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To obtain an actuator having simple structure which can be produced at lower cost than a magnetostrictive element and can expand/contract more than a piezoelectric element by employing a low cost piezoelectric material for the first layer and a conductive magnetostrictive material for the second layer. SOLUTION: A positive voltage is applied to each second positive layer 2a having conductivity and a negative voltage is applied to each second negative layer 2b having conductivity thus applying an electric field to each first layer 1. Consequently, the first piezoelectric layer 1 expands/contracts in the laminating direction of a multilayer element depending on the level of voltage applied through the second positive and negative layers 2a, 2b. When a magnetic field is applied to the element part 10 in the laminating direction by conducting a coil, each second positive and negative layers 2a, 2b also exhibiting magnetostrictive effect expand/contract in the laminating direction depending on the strength of magnetic field.  Consequently, the layer of element 5 at the element part 10 is elongated when a positive voltage is applied to the positive electrode 12 and a negative voltage is applied to the negative electrode 13.

Title: Production of inert gas
Inventor: SHIOMI YUTAKA
IPC: B01J19/14
Filed: 1985-08-27
Abstract: PURPOSE:To prevent the dew condensation, thermal impact, etc. of a piping, LPG tank, etc., without requiring heating by an external heat source such as electricity in a low pressure type inert gas generator by indirectly heating the inert gas of a low temp. dehumidified by a cooling type dehumidifier with air for combustion. CONSTITUTION:The combustion gas generated by mixing and burning the air compressed by a blower 1 and fuel makes countercurrent contact with ordinary- temp. cooling water by which the gas is subjected to cooling and dust removal. The gas passes through a demister and after microdroplets are removed from the gas, the gas flows to the cooling type dehumidifier. The inert gas subjected to the cooling and dehumidification arrives at a heater where the gas is indirectly heated by the air for combustion heated up to about 100 deg.C by the adiabatic compression admitted through a piping 7 and is sent to a user such as LPG tank. The air for combustion used for heating the inert gas is fed through a conduit 9 to the down stream of a valve 8 and is used as the air for combustion.

Title: Internal chill method for ferrous member
Inventor: SAGAWA NOBUMI
IPC: F02F1/00
Filed: 1988-07-30
Abstract: PURPOSE:To improve the suppression of the heat transfer based on an air gap in mating surfaces by positively guiding a molten light metal between the ferrous member and metal on the mating surfaces. CONSTITUTION:A bearing insert upper 2 is internally chilled by pouring of a molten Al alloy 8 into a metallic mold 1 and a cylinder upper block 9 is formed in the mold 1. The molten metal 8 flows even into a molten metal introducing path 7 of the mating surfaces 3 while extruding the air in the path 7 toward a vent hole 5 so that the molten metal eventually exists between the bearing insert upper 2 and the mold 1 as well on the mating surfaces 3. The air gap does no longer exist between the bearing insert upper 2 and the mold 1 on the mating surfaces 3. The quantity of heat of the molten metal 9, therefore, moves partly to the mold 1 via the bearing insert upper 2 and since the molten metal 8 exists between the bearing insert upper 2 and the mold 1, the heat transfer by conduction is executed and the transfer of the heat by the convection based on the presence of the air gap is eliminated. The heat transfer to the mold 1 is thus greatly improved.
