Title: Air-fuel mixture supply device of gas engine
Inventor: SHIMIZU MASAYUKI
IPC: F02B21/02
Filed: 1988-07-25
Abstract: PURPOSE:To secure a proper air-fuel mixing ratio in a broad range by connecting a gas passage to an air passage located in the stream upper than a gas mixer. CONSTITUTION:An air cleaner 3 and gas mixer 2 are connected by an air passage 4, and a gas passage 5 is connected to an air passage 4 located in the stream upper than the gas mixer 2. Since while the opening of a throttle valve 2a is little, the negative suction pressure of a gas passage connecting section is not increased more than required pressure, suction gas volume is not increased more than required volume. Since while the opening of the throttle valve 2a is large, negative suction pressure is increased even in the gas passage connecting section, suction gas volume is increased. This serves to secure a proper air-fuel mixing ratio in a broad range.

Title: Housing for pulse motor
Inventor: NAGANO SHINSUKE
IPC: H02K5/10
Filed: 1989-07-19
Abstract: PURPOSE:To prevent the invasion of water into a motor by forming a water releasing groove, guiding the water so as to flow down along the circumferential direction of a rotor shaft, on the flange unit of a housing. CONSTITUTION:A water releasing groove 14 is formed on the outer surface of a bracket unit 13 along the circumferential direction thereof. Water, invaded into a housing 10, is discharged quickly initially by forming the water releasing groove 14 on the outer surface of the bracket 13. There is a possibility that the water invades into the motor housing along a contacting site between a terminal base 4 and the bracket 13 while the invaded water arrives at a rotor 3 or a stator 2 along a rotor shaft 30 and generates rusting. The water releasing groove 14 guides the water to the lower part of the housing 10 and the water, invaded into the housing 10, is guided to the lower part of the stator 2 effectively while the water is discharged to the outside of the housing 10 through a water extracting hole (not shown in a diagram) formed on the housing 10.

Title: Apparatus for bending of plastic corrugated fiberboard
Inventor: MACHINO KUNIFUMI
IPC: B32B3/28
Filed: 1993-06-29
Abstract: PURPOSE:To prevent a V-shaped edge from warping even by heating by a method wherein the V-shaped edge forming a V-groove is connected to a fitting member with a suspended arm while a plastic corrugated fiberboard is being melted by heating. CONSTITUTION:A plastic corrugated fiberboard 5 is placed on an upper surface of a machine base 8, and a bending-objective part is set just under a V-shaped edge 6. Then, when a fitting member 7 is lowered to push the V-shaped edge 6 against the plastic corrugated fiberboard 5, the plastic corrugated fiberboard 5 is melted to form a V-groove. The V-shaped edge 6 is connected to the fitting member 7 with two suspended arms 16. That is, the V-shaped edge 6 is fixed to a position separated from the fitting member 7. Since the suspended arm 16 is interposed between the V-shaped edge 6 and the fitting member 7 without rigid contact with each other, thermal stress generated in the V-shaped edge 6 can be absorbed with the suspended arm 16.

IPC: G21K5/04
Filed: 1993-06-30
Abstract: PURPOSE:To provide a sterilizing method using an electron beam, capable of sterilizing even a portion behind a sterilizing object. CONSTITUTION:A sterilizing object 2 is placed in a polyethylene bag 4 as a housing member, and the bag 4 is sealed after forming atmospheric environment therein.
