Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a p-type SiC semiconductor single crystal, by which a growth speed of the level required for practical application can be obtained. SOLUTION: In the method for growing the p-type SiC semiconductor single crystal on a SiC single crystal substrate from a solution obtained by dissolving C in a Si melt, a solution obtained by further adding Cr and Al to the solution in an amount of 30-70 atom% and 0.1-20 atom%, respectively, based on the total amount of the Si melt, Cr and Al is used as the solution. Thereby, the crystal growth speed is enhanced because Cr enhances the solubility of C in the Si-C solution and Al functions as a p-type dopant and enhances the solubility of C in the Si-C solution like Cr.

Abstract: PROBLEM TO BE SOLVED: To provide a natural gas car having an occlusion type gas storage tank capable of controlling the filling amount of natural gas on each car side according to the characteristics of an adsorbing material. SOLUTION: A natural gas in a supply tank 18 in a filling place is fed to a storage tank 10 to store the natural gas in which an adsorbing material is accommodated, and at this time, a shutoff valve 24 is opened, and the operation is conducted while monitoring is made for the gaseous phase part pressure of the storage tank 10 and the temp. of the adsorbing material using a pressure sensor 12 and a temp. sensor 14. If filling is conducted while the filling pressure is kept constant, the temp. of the adsorbing material varies in a temp. pattern decided for each car depending upon the characteristics of the adsorbing material accommodated in the tank 10, the size of the tank 10, etc. The temp. pattern is stored previously in an ECU 16, and sensing is made on the basis thereof that the specified amount of natural has been fed, and the ECU 16 closes the shutoff valve 24, and thus the filling operation is terminated.

Abstract: PURPOSE:To increase the strength of a shim wall without increasing the thick ness of the shim wall by forming the shim wall of a valve lifter by means of reinforced fiber oriented in the vertical direction to the shim. CONSTITUTION:A plurality of prepregs 13 composed of carbon fiber of rein forced fiber 12 random oriented two-dimensionally to vinyl ester resin are lami nated and disposed in a compression molding die with a cavity of valve lifter shape, and the mold is heat pressurized. Then the prepregs 13 is filled in the inside of the cavity to form a molded material 10. At that time, the height of a bank section 11 on the cavity of the mold is formed higher than that of a shim wall 8 of a valve lifter 3 by 2-5 times. Then the bank section 11 of the molded material 10 and a processing margin are shaved into the shape of the dimension of valve lifter 3. The prepregs easily flows into the bank section 11 and the reinforced fiber 12 is easily oriented by said arrangement, and the reinforced fiber 12 is oriented in the vertical direction to the shim end surface at the shim wall 8 to increase the strength in the diameter direction.

Abstract: PROBLEM TO BE SOLVED: To provide the subject method capable of suppressing the temperature rise inside a storage container and increasing the storage density of a hydrocarbon gas in the container. SOLUTION: This method comprises the following procedure: top and bottom both ends of a hydrocarbon gas storage container 10 are furnished with methane inlets 20 in advance; to load the container 10 with a hydrocarbon gas, a CNG (compressed natural gas) is first introduced via the inlet 20 on the top of the container 10 into the container 10, and midway of the loading, the gas inlet 20 to be used is switched to the other gas inlet 20 at the bottom of the container 10; thereby a part where heat is generated at first is cooled owing to the adiabatic expansion of the CNG, and as for a part where heat is generated by introducing a CNG afterwards, temperature rise is suppressed since the temperature has fallen by the adiabatic expansion occurred when the CNG was introduced at first.
