Filed: 1987-12-10
Abstract: PURPOSE:To improve joining strength and welding workability of a stud bolt to a high damping steel plate by generating an arc intermittently between the stud bolt and one metal plate to burn down resin and welding the stud bolt to both metal plates deposited. CONSTITUTION:The stud bolt 6 is held by a holder 5 of a welding machine and abutted on one metal plate 2 of the high damping steel plate 1. The bolt 6 is then separated from the metal plate 2 and the arc A is generated repeatedly intermittently. The resin 4 between the metal plates 2 and 3 is burnt down by heat of the arc A and the metal plates 2 and 3 are deposited gradually. In this state, welding is performed under prescribed welding conditions between the stud bolt 6 and the deposited metal plates 2 and 3 to join the bolt 6 and the high damping steel plate 1 together. Since both steel plates 2 and 3 and the bolt 6 are deposited surely, the joining strength of the bolt 6 is improved. Since welding is performed from one side of the high damping steel plate 1, the welding workability is improved.

Filed: 1993-11-17
Abstract: PURPOSE:To prevent minute twisting vibrations by inserting a torque meter between a motor and a load and effectively utilizing its detect signal. CONSTITUTION:Deviation (e) between a velocity command input w* and an output omega(S) is subjective to stablizing compensation composed of a controller PI 1 to be one part of a state amount to give an output, T*(S).

Title: Dc source
Inventor: MURAKAMI YOICHI
IPC: G05F3/20
Filed: 1988-12-09
Abstract: PURPOSE:To reduce a stress applied to a component such as a rectifier even if the ON width of a transistor exceeds 50% by a method wherein a circuit detecting the output fluctuation of a primary source and a voltage control circuit are provided and a voltage induced on the primary winding of a transformer is controlled. CONSTITUTION:A detecting circuit 14 detects the output voltage (V1) of a primary source 1 and controls a transistor 16. For instance, if the voltage V1 is 20V, the charge voltage (VCO) of a capacitor 15 is controlled to be zero. If the voltage V1 is 30V, VCO is controlled to be 21.4V. As a voltage V3 induced on the winding N3 at that time is expressed by V3=V1-VCO, the voltage V3 can be reduced by the voltage VCO. As a result, a voltage induced on the collector of a transistor 2 can be suppressed.
