  • Patent number: 11229893
    Abstract: Provided is a method of producing a silicon compound material, including the steps of: storing a silicon carbide preform in a reaction furnace; supplying a raw material gas containing methyltrichlorosilane to the reaction furnace to infiltrate the preform with silicon carbide; and controlling and reducing a temperature of a gas discharged from the reaction furnace at a predetermined rate to subject the gas to continuous thermal history, to thereby decrease generation of a liquid or solid by-product derived from the gas.

  • Patent number: 10493868
    Abstract: An automobile seat includes a seat main body having a seat cushion frame; a seat supporting member; a link mechanism which allows the seat main body to shift between a first seat position and a second seat position corresponding to a forward-leaning posture; and a seat lock mechanism capable of being switched between a seat-locked state in which the seat main body is restrained at the first seat position and a lock-released state. The seat cushion frame is supported in a manner that a position thereof backward of the front link is suspended by the seat supporting member via the rear link. At the first seat position, a free-end supporting point of the rear link is positioned backward of a first vertical line passing a fixed-end supporting point of the rear link, and at the second seat position, the free-end supporting point is positioned forward the first vertical line.

  • Patent number: 10221104
    Abstract: A mixed gas containing a precursor gas, an additive gas and a carrier gas is supplied to a preform stored in an electric furnace, and silicon carbide is deposited by chemical vapor deposition or chemical vapor phase impregnation to form a film. The preform includes multiple fiber bundles, and the fiber bundles include multiple fibers. This heat-resistant composite material includes a ceramic fiber preform impregnated with silicon carbide, and producing the composite material involves a step in which silicon carbide is deposited between the fibers to integrate the fibers which configure the fiber bundles, and a step in which silicon carbide is deposited between the fiber bundles to integrate the fiber bundles. Hereby, uniformity of embedding and growth rate of the silicon carbide film are both attained.

  • Patent number: 10167549
    Abstract: In the present embodiment, in the production of a heat-resistant composite material resulting from impregnating a ceramic fiber preform with silicon carbide, a mixed gas containing starting material gas, an additive gas, and a carrier gas is supplied to a substrate having a minute structure such as a preform stored in an electric furnace, silicon carbide is deposited to form a film by means of a chemical vapor deposition method or a chemical vapor infiltration method, and the film formation growth speed and embedding uniformity are controlled by means of the amount of additive gas added to the starting material gas, the starting material gas contains tetramethylsilane, and the additive gas contains a molecule containing chlorine such as methyl chloride or hydrogen chloride. The film formation growth speed and embedding uniformity of the silicon carbide are both achieved.

  • Patent number: 9822445
    Abstract: By using chemical vapor deposition or chemical vapor infiltration, silicon carbide is deposited on a preform 100 accommodated in a reaction furnace 11 for film formation, and the amount of additive gas added to raw material gas and carrier gas to be supplied to the reactive furnace 11 is used to control the growth rate and filling uniformity at film formation of silicon carbide. When the film formation of silicon carbide follows a first-order reaction, the amount of added additive gas is used to control the sticking probability of the film-forming species. When the film formation of silicon carbide follows a Langmuir-Hinshelwood rate formula, the amount of added additive gas is used to make a control so that a zero-order reaction region of the Langmuir-Hinshelwood rate formula is used.

  • Patent number: 8472793
    Abstract: The present invention provides a technique for easily achieving a resume function for moving image content stored in one file in a removable recording medium. According to the present invention, a removable disc (Di1) in which moving image content stored in one file and another content are stored is played back, and, when playback of MPEG4 moving image file in the disc (Di1) that is played back is stopped and the disc (Di1) is removed, the file size, the file name, and the address of the MPEG4 moving image file are stored in a RAM 8. When the disc (Di1) is loaded again and the MPEG4 moving image file is played back, if it is determined that the disc (Di1) is identical to the removed disc by reading the file size and the file name stored in the RAM 8, playback of the MPEG4 moving image file is resumed on the basis of the address stored in the RAM 8.
