Title: Method for preventing leakage through pipe
Inventor: SAKAGUCHI SENZO
IPC: B05C7/08
Filed: 1989-12-02
Abstract: PURPOSE:To uniformly coat the inner surface of a pipe by moving a spherical pig connected to a wire in the pipe with compressed air and sucking up or agitating a coating or a mixture present mainly on the pipe bottom by the suction force produced on the rear surface of the pig when the pig is pulled back. CONSTITUTION:A coating consisting of the chiel agent and curing agent or a mixture 10 of the coating and reinforcement is injected from one separated end 1a of a pipe 1, and allowed to flow toward the other separated end 1b of the pipe 1 by compressed air 9 in a small quantity at a low pressure. The lightweight spherical pig 4 having a diameter slightly smaller than the inner diameter of the pipe and connected to a wire 5 is moved by the compressed air 9 from the end 12a to th end 1b, and the coating or the mixture 10 is moved in the pipe 1 and applied. When the pig 4 reaches the pipe end, the wire 5 is rewound to pull back the pig 4 against the compressed air 9, hence the mixture 10, etc., present mainly on the pipe bottom are sucked up or agitated by the suction force produced on the rear surface of the pig 4, and the entire inner surface of the pipe is coated.

Title: Manufacture of semiconductor device
Inventor: YAMAMOTO JIRO
IPC: H01L27/08
Filed: 1986-12-24
Abstract: PURPOSE:To reduce capacity between wirings, by leaving a silicon nitriding film on only a contact opening part for countermeasures of phosphorus out diffusion which is a problem occurring when a BPSG film is used as a layer insulating film. CONSTITUTION:A P<+> diffusion layer 2, in which boron is diffused. and a N<+> diffusion layer 3, in which arsenic is diffused, exist on a semiconductor substrate 1, and a SiO2 film 4 (BPSG film) is piled thereon so as to form contact holes. Next, a silicon nitriding film 5 is piled thereon and it is coated with a posi type resist 6. When anisotropic etching is next performed to remove the positive type resist 6 and the silicon nitriding film 5, then the resist remains on only a contact opening part whose resist film thickness is larger than that of the other part because the posi type resist 6 is low in viscosity, and resultingly the silicon nitriding film 5 remains on only the contact opening parts. When heat treatment is performed after removing the resist, phosphorus atoms coming from the BPSG film 4 do not enter the P diffusion layer 2 because the silicon nitriding film which covers the contact parts serves as a barrier. Thereafter, aluminium serving as electrodes is stuck thereon.

Title: Output circuit
Inventor: WAKAYAMA YASUSHI
IPC: H03K19/018
Filed: 1988-12-15
Abstract: PURPOSE:To decrease the power consumption of an output circuit by securing such a constitution where no current flows to a resistance element forming an emitter follower when the load connected to the output terminal of the output circuit is driven. CONSTITUTION:When the voltage level of an input terminal 10 is changed to 0 from VDD, an n channel MOS transistor TR 19 is turned off. Then the output voltage level of an output terminal 13 of a voltage level conversion circuit 12 is changed to VDD from (VDD-VSB). At the same time, the voltage level of an output terminal 18 rises up to (VDD-VBE). Under such conditions, the TR 19 is kept turning off, therefore no current flows to a resistance element 16. Then the emitter current of an npn TR 15 flows thoroughly to the load side via the terminal 10 to drive the load. Thus the power consumed by a fact that a current flows to the element 16 can be saved.

Title: Pressure vessel stand pipe support device
Inventor: DOMOTO ETSURO
IPC: G21C13/04
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To effectively support horizontal force and adjust against error, by making support structure having a cylindrical shape for absorbing displacement of thermal expansion of the pressure vessel in radial and axial directions and having controllability during a placement. SOLUTION: On the stand pipe 3 side, a cylindrical inclined support 4A is attached, and on the support member 5 side, an adapter 13 and a cylindrical inclined support 4 is attached. On the support 4, fixing holes 17 larger than fixing bolts 10 are provided. Therefore, by shifting fixing position left and right with the fixing holes 17 and spacers 14 and controlling the inclination between the support 4A and 4, placement error may be corrected. Thus, the relation between radial and axial thermal expansion quantities ΔR and ΔV during operation of the pressure vessel becomes ΔR/ΔV≈R/V, where the radial fixing position and the axial length of the stand pipe 3 are R and V, respectively. So by providing the slide surface of supports 4A and 4 with ΔR/ΔV inclination, it is not restrained by thermal expansion.
