Title: Electron beam welding equipment
Inventor: YAMAMOTO YOSHIHIRO
IPC: B23K15/00
Filed: 1985-06-10
Abstract: PURPOSE:To enable the automation by storing in an NC unit by measuring the slippage in the irradiation axis of an electron beam and the line to be welded and by operating the NC unit with this stored value. CONSTITUTION:The output of an electron gun 2 is reduced to that in the degree of not melting the material 4 to be welded. The dislocation of the irradiation axis of electron beam 2a with the line to be welded is detected by a weld line detecting device 6 from the waveform of the electron beam 2a scanning in the prescribed width on the line to be welded and the waveform of the X ray (4a) quantity emitted from the material 4 to be welded. The correction value of the dislocation according to this detected value is stored in the NC device 7 on each welding point. A table 3 is driven in the prescribed direction by a table driving device 8 when the NC device 7 is actuated by increasing the output of the electron gun 2 to the prescribed value and the weld line of the material 4 to be welded is welded by the irradiating electron beam 2a.

Title: Manufacture of optical part
Inventor: YAMAMOTO KATSUYOSHI
IPC: B29C37/00
Filed: 1988-05-25
Abstract: PURPOSE:To enhance not only the close adhesiveness of a resin to an optical membrane but also productivity, by coating the whole molding surface of a mold with an organosilicon compound by spraying to form a crosslinked layer to the surface of a resin and subsequently forming the optical membrane by a vacuum vapor deposition process. CONSTITUTION:A silane coupling agent is applied to the whole molding surface of a mold cavity (product molding part) at 100 deg.C or less at the opening time of a mold by spraying to form a crosslinked layer for forming an optical membrane having good close adhesiveness. The mold is clamped and a resin is injected in the mold to hold pressure and subsequently cooled to be plasticized while the mold is opened to cut a molded product at a gate and the optical membrane is formed by a vacuum vapor deposition method. Since the crosslinked layer improving close adhesiveness is obtained by an on-machine system and the molded resin can be subjected to vapor deposition as it is, productivity is improved. The crosslinked layer 3 and the optical membrane 2 are formed to the surface (spherical surface) of the obtained optical part 1. The whole film thickness is set to about 80Angstrom  or less.

Abstract: PURPOSE:To facilitate manufacture by providing a by-path passage which bypasses the fan of a supercharger, installing on the way a valve body mounted on a diaphragm driven by the differential pressure between upstream and downstream sides, and making the diaphragm mounting surface flush with the valve seat surface of a housing. CONSTITUTION:In the housing 31 of a supercharger, the first and second by-path passages 34, 35 are formed, and in the housing 31, a case 36 is fixed through a diaphragm 38. The edge of the second by-path 35 is takes as a valve seat part 39 which is flush with the surface of the housing 31 where the diaphragm 38 is installed to make into contact with a valve body 40 installed on the diaphragm 38, and the diaphragm is forced in the closing direction of the valve body 40 by action of a spring 42. At the time of middle and high load duty operation, a throttle valve is closed immediately, and when negative intake pressure increases, the pressure in the second by-path passages 35 increases to become positive high pressure, so that the valve body 40 opens, and pressurized air is circulated between by-path passages 34, 35. It is thus possible to prevent the pressure on the upstream side of the throttle valve from increasing.
