Title: Carburetor slow system controller
Inventor: SEKIYA MITSURU
IPC: F02M3/09
Filed: 1984-05-11
Abstract: PURPOSE:To match the control characteristic of slow system mixture gas path in a feedback control carburetor with that of main fuel system while to prevent paper lock by providing a bypath having smaller diameter than main path having large diameter and provided with a control valve then performing duty ratio control of said control valve. CONSTITUTION:Fuel fed from a float chamber through a fuel path 6 is weighed by a jet 7 while bleed air is weighed by a jet 9 then they are mixed in a chamber 8 and fed through main path having a large diameter jet 11 and a control valve 12 for opening/closing said jet 11 and a bypath 10b having a small diameter jet 13 to an idle port 4 and a bypass hole 3 provided near the closing section of throttle valve 2 for carburetor. The control valve 12 is subjected to conventional feedback control where the control width is set freely on the basis of the diameters of said jets 11, 13 to match the characteristic with that of main fuel system while since the mixture gas exists at the control section, occurrence of paper lock at this section can be prevented.

Title: Thermal insulating grainy material filling method for vacuum thermal insulated double shell tank
Inventor: NAKABAYASHI HIROSHI
IPC: F17C3/02
Filed: 1987-04-17
Abstract: PURPOSE:To fill a thermal insulating space with a thermal insulating material, closely with sufficient pressure, by forming a pressure resisting ventilation stratum in the thermal insulating space between an inside tank and an outside tank, for equalizing the external pressure which acts on the upper part and the lower part of the inside tank. CONSTITUTION:A vacuum pipe 4 is formed at the lower end of a thermal insulating space 3 between an inside tank 1 and an outside tank 2, and a thermal insulating material filling port 5 is formed at the top of the outside tank 2. A ventilation stratum 7 which has pressure resistivity, is formed on the inner surface of the outside tank 2. Accordingly, the external pressure which acts on the upper part and the lower part of the inside tank 1, is always equalized. As it is prevented that a vertical force acts on the inside tank, when the thermal insulating space is filled with a thermal insulating grainy material, the space is filled with this material closely with sufficient pressure.

Title: Formation of multi-layer wiring
Inventor: FUSHIMI KIMIHISA
IPC: H01L21/768
Filed: 1989-04-13
Abstract: PURPOSE:To prevent short-circuiting between first and second wires by forming an aluminum hydrate at an abnormal protruding part of a first-layer wire which is exposed on an interlayer insulation film, namely an aluminum hillock. CONSTITUTION:Etching at nearly the same etching rate is performed to a sacrificing film 35 and an interlayer insulation film 33, formation treatment is performed to an abnormally protruding part of a first-layer wire 32 which is formed before the process for exposing the flattened interlayer insulation film 33 and which is exposed on the interlayer insulation film 33, and a process for forming an aluminium hydrate 36 at least at the surface-layer part of that abnormally protruding part is added. Thus, by performing formation treatment at the abnormally protruding part of the first-layer wiring 32, namely at an aluminum hillock 34, and by forming the aluminium hydrate 36, the aluminum hydrate 36 functions so that it insulates and coats the aluminium hillock 34. Thus, even if a second-layer wiring 38 which is formed at the succeeding process may contact the aluminium hillock 34 through the aluminum hydrate 46, insulation is maintained on both sides, thus preventing short-circuiting between the first wiring 32 and the second wiring 38.

IPC: H02M3/335
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To attain stable output without being affected by a primary unit voltage fluctuations. SOLUTION: This power supply unit is provided with a main power supply part having a drive transformer T1 for controlling switching transistors Q1, Q2 and the switching frequencies of the transistors Q1, Q2, and a converter transformer T2 and an auxiliary power supply part having a switching transistor Q3 and a flyback transformer T3, through which current is flowed intermittently by the transistor Q3.
