Abstract: PROBLEM TO BE SOLVED: To provide a method for reutilizing a combustible diluting gas component used as a reactional diluent medium and inert to a reaction as, e.g. an energy source for a thermoelectric generator.  
     SOLUTION: This method for continuously operated heterogeneous catalytic gas phase partial oxidation of an organic compound is to subject the organic compound to the continuously operated heterogeneous catalytic gas-phase oxidation in an oxidizing reactor in which a feed gas mixture for the oxidizing reactor contains at least one kind of a diluting gas (e.g. propane) kept in a mainly inert state under the heterogeneous catalytic gas-phase partial oxidizing conditions in addition to the organic compound to be partially oxidized (e. g. propylene) and molecular oxygen as an oxidizing agent.

Filed: 1991-03-18
Abstract: PURPOSE:To reduce the junction capacitance of an insulating gate transistor so as to make the transistor higher in processing speed by eliminating the cause of carrier scattering and bringing the mobility of the carriers closer to that peculiar to a semiconductor material. CONSTITUTION:An area 5 is an insulating film which is used as the insulating film for the gate of an MOS transistor and SiO2, Si3N4, TiO2, TaO2, etc., and their composite film are used from forming the insulating film 5. A region 6 is a gate electrode made of p<+> or n<-> polysilicon. While the n<-> polysilicon is preferable for short channels, but n<+> polysilicon can also be used. It is important to allow carrier electrons 20 to run in the region 6 apart from the boundary between the film 5 and a semiconductor. Therefore, the scattering of carriers caused by the unevenness of the boundary can be reduced. In addition, the cause of the scattering of the carriers can be eliminated by controlling the width and impurity concentration of the carrier running region.
