Title: Electric discharge coating device
Inventor: INOUE KIYOSHI
IPC: C23C26/00
Filed: 1982-05-12
Abstract: PURPOSE:To provide an electric discharge coating device which is constituted to form a thick and dense coating layer with small surface roughness and smoothness of the coating surface, by applying rotating motion around a shaft in the attaching and detaching directions to an electrode of a coating material during the period from the stage of attaching until detaching. CONSTITUTION:As an electrode 1 of a coating material descends and approaches the work 2 and the spacing therebetween attains a breakdown spacing, electric discharge is generated by the voltage applied on the electrode 1. The forward end of the electrode 1 is melted by the electric discharge heating and the contact electrical heating in the state of the contact upon the contact of the electrode with the work 2 that takes place next to the discharge heating. The molten electrode is transferred and welded to the work 2. Since the electrode 1 is kept rotated around the shaft thereof during said time, the welded part by electric discharge is torn off by the rotation of the electrode so as to rub off the welded part prior to detaching. The surface of the work 2 is formed to a smooth finish surface by the breakdown or the control of the coated surface by the rubbing as well as the electric discharge generated upon starting of the contact by the oscillation with the rotation, whereby the electric discharge coating having less cavities and weak parts of the coating is obtained.

IPC: G01R33/385
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To controll an offset current even in resonating operation of a gradient coil by generating a gradient offset current for incomplete discharging of a capacitor, and by causing a voltage difference between the gradient coil and the capacitor besides a voltage drop in a resistance. SOLUTION: A capacitor voltage UC does not reach to zero only at every two half-waves, in the half-wave stationed between them, a residual voltage UCR remains until a capacitor C is charged again by a current IG from a gradient coil G. A constant offset current as a direct-current component and a gradient current IG compounded from a generally sinusoidal superimposed alternating- current component are generated. By controlling switches T1, T3, at a certain interval, the gradient coil is connected directly to a gradient amplifier GV, and a direct current of a proper span can be flowed into the gradient coil without relation with the sinusoidal current and the offset current.
