摘要： An electronic fuel injector capable of supplying fuel in a stable manner is provided by employing a swirler, which is manufactured at a lower cost and has durability, and by ensuring superior wear resistance of the swirler and a valve member provided on a movable part, which is put into frictional contact with the swirler. The electronic fuel injector comprises a movable part, a valve member, a valve seat, a swirler, a stopper, a stator core, a casing, a spring, and an electromagnetic coil. A valve member is provided at a fore end of the movable part. The swirler serves not only to swirl fuel, but also to guide movement of the valve member provided at the fore end of the movable part. The swirler is formed of a powder sintered compact of martensitic stainless steel having corrosion resistance and wear resistance.

摘要： A glow discharge surface treatment process wherein only the selected portions of a workpiece adjacent to or surrounded by the associated secondary electrodes are surface-treated so as to provide different treatments on the workpiece according to the position of the secondary electrodes. The each secondary electrode is provided close to at least a portion of the workpiece, and the workpiece and the associated secondary electrode are both connected to the cathode. When a voltage is applied between the cathode and the wall of the container in the treatment apparatus which forms the anode, mutual interference effect (which is referred to as a hollow cathode effect) of negative glow discharges is established between the workpiece and the associated secondary electrode so as to accelerate the heat treatment for the selected portion of the workpiece surrounded by the secondary electrode. The gas pressure in the container is varied to control the hollow cathode effect. In the treatment process of the present invention, the workpiece is thermally treated so as to provide differently treated portions therein.
