    摘要: A TIG welding method is usually carried out in a manner that a tungsten electrode is inserted into a weld groove portion of a member to be welded, an electric voltage is applied to a current conducting portion provided for the tungsten electrode while flowing a shield gas means to thereby generate an arc between the tungsten electrode and the member to be welded to form a molten pool of the member, a welding wire is inserted into the molten pool, and a welding torch is then operated to perform a welding process. In the improvement of the TIG welding method, the shield gas means is composed of an inner shield gas flowing from a periphery of the tungsten electrode to a front end thereof inserted into the weld groove portion of the member to be welded and an outer shield gas flowing towards the weld groove angle from an outside of the inner shield gas to prevent the molten pool from being oxidized and to prevent oxygen in air from being involved. The TIG welding torch for carrying out the method is specifically provided with the inner and outer shield gas flow means, and further provided with a central shield gas flow means.

    摘要: A fuel injection control apparatus is capable of reducing a minimum quantity of fuel injection without reducing a maximum quantity of injection. To open a fuel injector valve, a driving circuit supplies an electric current from a high-voltage power supply to the fuel injector. Then, after valve opening, the high-voltage power supply is switched to a low-voltage power supply, and an open state of the valve is retained. For opening the valve of the fuel injector, a microcomputer, after supplying current from the high-voltage power supply to the injector, discharges the current rapidly for a decrease below a first current level at which the open state of the valve cannot be retained. The microcomputer then controls the supply current to the injector so as to supply a current at a second current level at which the open state of the valve can be retained.

    摘要: A valve structure which works easily, does not increase production cost, can reduce dispersion in a side gap by restricting eccentricity and incline of a valve body and can maintain highly accurate injection. An electromagnetic fuel injection valve is required which is easy to manufacture even in a narrow valve structure. A guide portion is provided having one end fixed to an injection valve main body for guiding the valve member. A nozzle guide body constituting a magnetic passage portion to surround a magnetic member connected and fixed to one end of the valve member by the same material is provided. Accordingly, it is possible to reduce dispersion of a side gap constituting the magnetic passage, and it is also possible to stabilize an axial motion of the valve member, whereby high injection accuracy is maintained and an inexpensive injection valve is obtained.
