Title: Pressure vessel for gas-insulated switchgear
Inventor: KIKKO YOSHIAKI
IPC: H02B13/02
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To reduce the longitudinal dimension of the unit of a gas-insulated switchgear and simplify machining of the outer edge of its flange part to reduce cost. SOLUTION: Electrical apparatuses such as breakers, disconnectors, ground switches, etc., or conductors are housed and insulating medium such as SF6, etc., is sealed in a pressure chamber for a gas-insulated switchgear. The body part 14 of the pressure vessel of the gas-insulated switchgear has an elliptical cross-section, and the shapes of the outer edges of flange parts 15 which are connected to the end parts of the body part 14 are circular. Since the body part 14 has an elliptical cross-section, if the short diameter direction is made in parallel with the longitudinal direction of a unit, the longitudinal dimension of the unit can be reduced.  Furthermore, since the shapes of the outer edges of the flange parts 15 are circular, machining can be practiced by turning a tool concentrically, so that the machining can be very much simplified, and the flange parts can be made at a low cost. Also, a circular O-ring groove 16 can be machined easily.

Filed: 1995-01-20
Abstract: PURPOSE: To ensure high heat and acid resistances and to prevent the deterioration of adsorbing performance even by the adsorption-desorption of NOx by making oxide of Ru and/or Ce carried on an Mn-Ti surface-modified titania carrier obtd. by adding an Mn compd. to amorphous titania and firing them. CONSTITUTION: An aq. manganese nitrate soln. is impregnated into amorphous titania obtd. by drying a titania colloidal soln. prepd. by a nitrate hydrolysis method and the titania is fired to obtain an Mn-Ti surface-modified titania carrier. Oxide of Ru and/or Ce is carried on this carrier to produce the objective NOx adsorbent.

Title: Sheet for heat radiation
Inventor: KIMURA NAOKI
IPC: C08L33/06
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To attain excellent thermal connection between electronic parts, etc., and a heat sink due to excellent following property when coming into contact with the electronic parts, etc., to be cooled or the heat sink, by a method wherein a soft metal layer and a rubber layer covered on one face or both faces are provided. SOLUTION: A heat radiating sheet comprises a soft metal layer and a rubber layer covered on one face or both faces, and has high softness. Further, differing from a thing in which rubber or a rubber composition is only molded in a sheet, it is hard to be torn to pieces or holds high intensity. Thus, the radiating sheet is hard to be broken or cause creases when setting it at a specified position, etc. For this reason, in works, etc., of interposing the sheet between a heat sink and parts to be cooled, the work becomes simpler. Further, as a soft metal layer is soft, when the radiating sheet is pinched between the heat sink and the parts to be cooled, it is excellent in following property for small and large recesses and projections on a surface of the heat sink and the parts to be cooled. For this reason, high thermal connection between the heat sink and the parts to be cooled can be attained.

Filed: 1992-01-22
Abstract: PURPOSE:To prevent a drop in the temperature of a cathode part which is in contact with an insulator for controlling a cathode vibration by heating the insulator with heaters at both upper and reverse sides thereof; prevent the insulator against electrification by applying AC voltage to the heaters; and further prevent the flow disturbance of an electron beam by reversing heater current flows from each other on the upper and reverse sides of the insulator. CONSTITUTION:A ceramic plate 19 is erected on the upper side of a back plate 11, and grooves 20 are formed on the plate 19 where in contact with cathodes 2. Also, the plate 19 is fixed to the plate 11 with a glass adhesive 21. Heaters 22 are provided at both sides of the plate 19, and this plate 19 is reduced in cross sectional area at a position near the grooves 20 for generating local heat. The position and height of the cathodes 2 are restricted with the grooves 24 of ceramic seats 23 on the edges of the plate 11. Also, the cathodes 2 are extended by using fasteners 25 and spring fixtures 26. As a result, the vibrations of the cathodes 2 are controlled, due to contact with the grooves 20, and the heaters 22 prevent the partial loss of an emitted thermion amount. Also, AC voltage is applied to the heaters 22, thereby preventing the vicinity of the plate 19 from being charged with electrons, and electric current flows are reversed from each other on both sides of the plate 19, thereby offsetting magnetic field. According to this construction, a whole screen becomes homogeneous.

Title: Seal mechanism in tire pneumatic pressure regulating device
Inventor: NISHIMURA HIROAKI
IPC: B60C23/00
Filed: 1985-01-21
Abstract: PURPOSE:To aim at enhancing the durability of seal members, by forming a communication hole for communicating between a fluid pressure source and a tire pneumatic chamber, in an axle, and by sealing up the opening end of the communication hole at the outer peripheral surface of the axle with the use of a fluid pressure seal member which is extended and retracted by the internal fluid pressure. CONSTITUTION:When the pressure 39 in a tire pneumatic chamber is at an appropruate value during stoppage of an engine, a solenoid changeover valve 38 closes an air pipe 24, and a solenoid changeover valve 40 communicates a fluid pipe line 23. Accordingly, the pressure in a tire pneumatic pressure chamber 7 acts upon fluid chambers 19 in fluid pressure seal members 17, 18 through a peircing hole 8, a through-hole 9, an air-gap 25, an air pipe line 24 and a fluid pipe line 23 to inflate the seal members 17, 18 so that they fasten an axle 2 to seal up the same. When the engine is driven, the solenoid changeover switch communicates the fluid pipe line 23 to the discharge side to allow a fluid chamber 19 to open to the atmospheric air, and therefore, the seal members 17, 18 deflate to decrease their fastening force. With this arrangement, the abrasion of the seal members may be reduced thereby it is possible to enhance the durability thereof.
