Title: Forming method of silicon film on polycrystalline silicon film
Inventor: MATSUYAMA NOBUYOSHI
IPC: H01L21/3205
Filed: 1989-07-24
Abstract: PURPOSE:To obtain an insulating film excellent in the uniformity of film thickness, by forming a polycrystalline silicon film, turning said film into P<+> type, and forming a thermal oxidation film on the polycrystalline silicon film. CONSTITUTION:A polycrystalline silicon film 3 is formed, and after said film is turned into P<+> type, a thermal oxidation film 5 is formed on the polycrystalline silicon film 3. For example, on the surface of a P-type silicon substrate 1, a silicon oxide film 2 is formed, and thereon a polycrystalline silicon film 3 is formed to be 4000 Angstrom  thick; said film 3 is turned into P<+> type; then a polysilicon thermal oxidation film 5 is formed in an oxygen/nitrogen atmosphere at 1000 deg.C. Thereby it is possible to minimize the variation in thickness of the thermal oxidation film which is nonuniformly formed on a wafer when it is carried in and out of an oxidizing furnace and the variation of the oxide film thickness caused by the irregurality of the impurity concentration in the polycrystalline silicon layer in the wafer.

Filed: 1985-09-02
Abstract: PURPOSE:To send an output signal whose polarity is coincident with the active polarity of a connection destination input signal by providing a circuit storing the active polarity of an output signal inputted externally and a polarity inversion circuit of the output signal in response to the storage content. CONSTITUTION:A tri-state inverter type buffer 4 is turned on by a reset signal fed to an input terminal 2 via a connection line 7 and an output signal connection line 10 is made inactive, then the tri-state buffer 3 is turned off.An external signal to the integrated circuit representing the polarity of the inactive state at reset is fed to an output terminal 1 and inputted as a data of a D FF-5 via a connection lines 6, 8. When the inactive polarity at the output terminal 1 is logical '1', the output of the FF5 goes to logical '0' and when the polarity is logical '0', the output of the FF 5 goes to logical '1'. Thus, the output signal whose polarity is coincident with the active polarity of the connection destination input signal is sent.

Abstract: PURPOSE:To prevent rapture or the like of a metallic tube due to excessive deformation by a method wherein a plurality of ceramic rings are fitted to the outside of the metallic tube to absorb the deformation due to the temperature and pressure of the metallic tube in the heat exchanging tube heated by high-temperature gas. CONSTITUTION:When heating gas and gas to be heated are flowed through a heat exchanger, heat possessed by the heating gas is transferred to the ceramic rings 15, then, the heat is transferred to the metallic tube 11 and the gas to be heated is heated. A room remains between the closed end of the metallic tube 11 and a fireproof and heat insulating member 5 and a press tube 4 is also energized by a spring or the like, therefore, the metallic tube 11 may be displaced into the axial direction thereof. Accordingly, the metallic tube 11 as well as the heat exchanging tube 10 are free from expansion and contraction due to the change of temperature and, therefore, the bending or breakage of the metallic tube 11 or the breakage of the ceramic rings 15 will never be caused upon using under a high temperature. The metallic tube 11 expands into the radial direction thereof by heating, however, such deformation may be absorbed by a space provided between the metallic tube 11 and the ceramic rings 15 and the high- temperature heating of the high pressure gas to be heated may be effected safely and surely.

IPC: G11B21/21
Filed: 1987-08-01
Abstract: PURPOSE:To improve floating stability by setting a loading point to the almost intermediate part of the air flowing direction length of a slider in which a taper surface is removed. CONSTITUTION:Since the loading point is set to the almost intermediate part (b) of an air flowing direction length Lo of a slider 1 in which a taper surface 102 is removed in the air flowing side of a floating surface 101 to face to an magnetic disk M, the loading point is moved to an air flowing edge side, loading is decreased in an air flowing-in side provided with a taper surface 102 and the loading is increased in an air flowing-out side. As a result, even when a slider 1 floating surface is made narrow and low floating quantity is obtained, a lifting dynamic pressure and the loading is equalized, a forward falling state is evaded and a flight attitude, in which the floating surface 101 is almost parallel with the surface of the magnetic disk M, is kept. Thus, a stable floating characteristic can be secured.
