Abstract: A first laser beam is radiated to a first radiation position of a welding object while intersecting a wire, and a second laser beam is radiated to a second radiation position that is spaced a predetermined distance from a target position of the wire. Arc welding is performed between the wire and the welding object while radiating the first laser beam and the second laser beam such that the first radiation position, the second radiation position, and the target position are disposed on a welding line of the welding object. In this way, it is possible to prevent the generation of spatter and perform welding at a high rate, without increasing the size of a molten pool.

Abstract: Disclosed is a method for hybrid welding in which a laser beam is applied to the welding position of objects to be welded, and at the same time, a first wire is fed to the welding position so as to perform arc welding using an arc generated between the objects to be welded and the first wire. In this method, one or more second wires are fed to a molten weld pool formed by the laser beam and arc welding, thereby increasing the amount of welding without increasing the arc current.

Abstract: An oilless screw compressor incorporating water-cooled cooling units for cooling compressed air discharged from compressor bodies having a pair of male and female screw rotors which can be rotated in a contactless and oilless manner, the cooling units comprising a plate type heat-exchanger, and the amount of cooling water for the plate type heat-exchanger being adjustable. With this configuration, a difference between a temperature during load operation and a temperature upon automatic stopping and during unload operation of the compressor can be reduced, so that the cooling unit can be restrained from being damaged or broken within a short period, thereby it is possible to provide a highly reliable oilless screw compressor.

Abstract: A multi-stage oil-free screw compressor includes: a suction throttle valve for controlling air intake into the compressor; a piston assembly for operating the suction throttle valve; and a structure for supplying a working pressure to the piston assembly. In order to reduce startup load at the time of startup of the compressor, the suction throttle valve is fully closed while a secondary side of a compressor body is opened to the atmosphere. When a negative pressure and the air pressure, that provide the working pressure, are used for slightly opening the suction throttle valve in order to switch the compressor to a loaded mode after a motor for driving the compressor is accelerated to its top speed, the air pressure is provided by a control pipe line that is defined by the same pipe line that forms a drain pipe line. This permits the control pipe line to be opened to the atmosphere as needed during the startup time. Thus is provided the oil-free screw compressor achieving improved startup reliability.

Abstract: The visual line detection device according to the present invention is capable of accurately detecting the visual line of the eyeball of an observer, even though it uses light sources which are only a finite distance away from the eyeball, i.e. which are not effectively at infinity. At least two infrared light emitting diodes are provided for illuminating the eyeball, and the position of the center of curvature of the cornea of the eyeball is obtained based upon the positions of a plurality of images generated by the light rays emitted by these diodes being reflected from the cornea. The direction of the visual line of the eyeball is then calculated using this position of the center of curvature of the cornea. A camera according to the present invention is also disclosed which incorporates such a visual line detection device.

Thereby, it is possible to make the motor relatively low in rotating speed while inhibiting the gears from being increased in diameter, thus enabling achieving reduction in cost.
