Title: Supercharging controller of internal combustion engine
Inventor: KAMIOKA KIYOSHIRO
IPC: F02B37/18
Filed: 1994-09-08
Abstract: PURPOSE: To prevent such a possible that a catalyzer might come to an undue temperature rise due to the effect of supercharging in time of a misfire occurrence, in such a constitution that there is no fuel-cut immediately after the misfire has happened. CONSTITUTION: Fuel is fed to a combustion chamber 4 of an engine 1 by an injector 11. Air to be fed to the combustion chamber from an intake passage 6 is supercharged by a supercharger 21. Exhaust gas to be exhausted to an exhaust passage 7 from the combustion chamber 4 is purified by a three-way catalyst. In this engine 1, when the generation rate of a misfire in the combustion chamber 4 grows larger to some extent, a supply of fuel by the injector 11 is cut off. Supercharging by the supercharger 21 is controlled according to a driving state of the engine 1. Here, the misfire happening in the combustion chamber 4 is detected by a crank angle sensor 46 or the like.  An electronic control unit(ECU) 50 opens an air bypass valve(ABV) 32 at the time of judging the generation of the misfire on the basis of the detected result of the sensor 46 and restricts the operation of the supercharger 21, whereby the supercharging is reduced at once.

Title: Method for correcting deflection of printed wiring board
Inventor: ARAI TAKAFUMI
IPC: H05K3/22
Filed: 1992-08-13
Abstract: PURPOSE:To achieve accurate warp correction by deforming a printed wiring board in the direction opposite to the warp with a displacement amount according to a contact pressure distribution. CONSTITUTION:The surface of a printed wiring board 1 is pressed with a sheet- shaped pressure sensor 2 to determine the contact pressure distribution of the printed wiring board 1 with the sheet-shaped pressure sensor 2. Then, the warp of the printed wiring board 1 is corrected according to the contact pressure distribution. That is, a warp correcting disk is set above an elastic disk 7 instead of a pressing disk 3, and the warp correcting disk is moved downwardly to press the printed wiring board 1 in the direction opposite to the deflection thereof, forcibly warping the board. Since the printed wiring board 1 is supported by the elastic disk 7 on the underside thereof and the board is warped while the elastic disk 7 is concavely compressed, the stress can be dispersed, so that breakage is prevented from occurring in the printed wiring board 1 at a V-groove or sewing machine stitch. Thus, the warp of the printed wiring board 1 can be corrected.

Filed: 1988-08-30
Abstract: PURPOSE:To reduce an interference part and an unshaved part by deleting the offset point of a closed passage part on the projection passage of an offset passage and correcting the offset passage at two points on an offset having its start point coordinate value. CONSTITUTION:A loop closed passage LP exist on a projected passage OFPi' (Q'1 Q'2 Q'3 Q'4) obtained by projecting an offset passage OFPi on a copy plane. A processor 1a obtains two-dimensional coordinate values xa and za of a start point S of the closed passage LP of the i-th projected passage OFPi'. It also obtains two three-dimensional coordinate values Q''2 and Q''3 on the i-th offset passage OFPi which shares the coordinate values and they are stored in a RAM 1c. Next, the processor 1a deletes offset points Q2 and Q3 corresponding to the closed passage part LP and makes the two three-dimensional coordinate values Q''2 and Q''3 obtained previously into new offset points. The i-th offset passage OFPi is corrected to Q1 Q''2 Q''3 Q4 and outputted as NC data.

Title: Sector wheel of radial gas turbine
Inventor: NISHIWAKI JINICHI
IPC: F01D5/04
Filed: 1989-08-24
Abstract: PURPOSE:To heighten thermal efficiency of a radial gas turbine by constituting a cooling air flow passage in a sector wheel. CONSTITUTION:The first flow passage 12 divided in the radiant direction by a plural number of fins 9 and a cover 11 is formed on the back surface of a sector wheel 7. Compressed air 2 flowing out on the surface of the sector wheel 7 from a plural number of small holes 10 through the first flow passage 12 from the second flow passage 15 cools down the sector wheel 7 by way of contacting the back surface of the sector wheel 7, a small hole wall and the fins 9, and after flowing out from the small holes 10, it flows along the surface of the sector wheel 7 and forms a heat blocking film with air on its surface. Consequently, the degree of the sector wheel to be heated by a high temperature gas flow is lessened. Subsequently, the air flown into a hollow wing 8 formed projected on the surface of the sector wheel 7 cools down the wing from its inside, flows out from small holes 23 on its side and forms a heat blocking film along the wing 8. Accordingly, the degree of the wing 8 to be heated is lessened. Consequently, it is possible to heighten the temperature of working gas 5 and the thermal efficiency of a radial gas turbine.

All the tooth areas 5c are sheared so as to be twisted in the same direction, and the end of each tooth area 5c is arranged in a serrated shape as viewed from the center of the round hole 5a. And the tooth area 5c is twisted to be formed at such an angle that it is engaged with the helical spline of a shaft. The plastic deformation is applied to the both surface sides of the tooth area 5c and chamber 5d is applied thereto so that its contact area with the shaft is increased.
