IPC: B23K26/346
Filed: 1986-05-08
Abstract: PURPOSE:To improve the starting properties of an arc and to improve directivity of the arc under a welding condition with a wide range by spot-projecting laser beams on metal materials as materials to be welded to generate heat thereon and applying an electric current between the heat generating part and an electrode of a TIG welding machine to generate the arc. CONSTITUTION:The laser beams from a laser oscillator 5 are converged by a convex lens 7 through an optical fiber 9 and a focus is formed on a weld zone of an object 1 to be welded consisting of the metal materials to heat the weld zone. The position of the focus is set ahead in the welding progressing direction B by A from the position right below the W electrode 3 in a torch nozzle 4 of the TIG welding machine. Since this focus part is rapidly heated and a large quantity of thermoelectron is emitted, the arc 11 is easily generated between the focus part and the acute tip of the W electrode. Moreover, the directivity of the arc is improved under the welding condition with the wide range and a weld bead with narrow width and deep penetration is easily obtained.

Title: High-speed reluctance type motor
Inventor: BAN ITSUKI
IPC: H02P25/08
Filed: 1991-02-12
Abstract: PURPOSE:To obtain a high-speed, high-torque and efficient reluctance type motor. CONSTITUTION:When the current application to one exciting coil 32 is stopped, the magnetic energy accumulated in a magnetic core is prevented from circulating into a power source side by the diode 49a for prevention of reverse currents, but is charged into a small capacity of capacitor 47a so as to maintain it at high voltage, so the drop of a current becomes rapid. Though the next exciting coil 32d is supplied with a current after a certain time, the voltage applied at this time becomes a charge high voltage of the capacitor 47a, so the current starts up quickly. Since the rise of the current application of the exciting coil 32a and the drop becomes quick, it can rotate several ten thousands times per minute. A means for replenishing the energy loss by copper loss and iron loss by applying a current to an inductance coil at current application to the exciting coil 32a and charging the magnetic energy of both into the capacitor 47a and applying a current to the next exciting coil to be supplied with a current is also adopted.
