Title: Production of amorphous silicon film
Inventor: TANAKA KAZUNOBU
IPC: C23C16/52
Filed: 1982-11-22
Abstract: PURPOSE:To stabilize the production of a-Si films having a constant high quality by providing a method in which an optimum plasma state is set and maintained through a feedback of luminous intensity ratio of luminous neutral nuclides as measured by a plasma measuring means. CONSTITUTION:After setting a substrate 1 on a substrate holder 2 serving also as an electrode, air is induced through an opening 4 of a film-forming tank 3 to establish a vacuum in the latter. Then, a material gas is charged into the tank 3 through a gas introduction port 5 and high-frequency electric power is supplied by a source 7 to an electrode 6, thereby generating a plasma in the tank 3. Consequently, an a-Si film is formed on the substrate 1 by deposition of the substances produced by decomposition of the material gas. This method is known as ''plasma CVD method''. During the formation of the a-Si film, the state of the plasma in the tank 3 is watched and measured by a plasma luminescent analyzer 9 through a window 8, and a computation is made to determine a ratio SiH/H between the luminous intensity of the luminous neutral nuclide SiH and that of the luminous neutral nuclide H. The computation result is fed back to a plasma controller 11 which in turn controls, on the basis of the computation result and previously given data, the high-frequency power supplied by the source 7 to the electrode 6 in such a manner as to attain a greater value of the ratio SiH/H.

Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To ensure that a burner is caused to generate a flame reaction rapidly regardless of the total length of use over years and thereby a lighting in a heating chamber is obtained. SOLUTION: When the degree of grilling of a material to be cooked needs to be checked, an igniter is activated to continuously discharge electricity to a vessel 14 from an electrode 16. The vessel 14 stores a solid 15 of sodium chloride containing a deliquescent substance in such a state that the surface of the slid 15 is wet. Therefore, the surface of the solid 15 becomes a spark passageway and the on of the sodium chloride is locally heated to start the instantaneous vaporization of the sodium chloride. The vaporized sodium chloride is sucked from a primary air suction aperture 12 together with a primary air, and in the throat part 9, gas, air an a sodium chloride vapor are mixed and the mixture is supplied to each of flame holes 7, 7... for cooking.  Consequently, the flame colors of the flame holes 7, 7... for cooking change from a routine blue to yellow due to the flame reaction of the sodium chloride, and the interior of a heating chamber 2 is thoroughly lighted by the entire yellow flame.

IPC: F04B49/00
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To provide a variable displacement compressor, by which during high speed rotation of an external driving source, stable capacity control can be achieved. SOLUTION: A weighty part 61 is provided on the outer peripheral surface of a swash plate 21 to be the mass existing in a position most separate from the axis L of rotation in the swash plate 21. Accordingly, when a vehicle engine is rotated at high speed, larger centrifugal force is applied to the swash plate 21 so as to enlarge the moment in the direction of decreasing an angle of skew applied to itself due to the centrifugal force. As the result, even if the moment in the direction of increasing the angle of skew applied to the swash plate 21 is enlarged by the piston inertia force, the moment in the direction of increasing the angle of skew is cancelled by the moment in the direction of decreasing the angle of skew to be lessened.
