    摘要： A process for manufacturing an Alnico system permanent magnet is disclosed in which the alloy powder of the Alnico system having the proper composition is manufactured through a rapid solidification process, so that the crushability and the formability should be superior, the sintered density should be high, and the magnetic properties should be excellent, as well as cheap in its manufacturing cost and simple in its manufacturing process. An alloy of Alnico system is subjected to a rapid solidification with a spinning solidifier wheel speed of 6-40 m/sec, thereby manufacturing a microcrystalline rapidly solidified powder. The powder is ground into a finer powder, and then a press-forming is carried out. Then a sintering is carried out at a temperature of 1100.degree.-1350.degree. C. for 0.5-4 hours. Then based on a single heat treatment, an external magnetizing force of 1-15 kOe is applied in a temperature range of 600.degree.-1000.degree. C., thereby carrying out a heat treatment under a magnetizing force. Thereafter, an aging heat treatment is carried out at a temperature of 500.degree.-700.degree. C. for 1-10 hours, thereby magnetizing the formed body.

    摘要： A resistor device for controlling a rotational speed of a resistance unit and an open-circuit means. A receiving recess is provided to any one side surface of a heat sink vertically affixed to a top surface plate of a housing. A resistance unit, which is protected by a film and made of metal material forming a resistor circuit for gradually controlling the rotational speed of a motor, is received within the recess in the heat sink and connected to a terminal. An open-circuit means, having a soldered portion which is fused at a predetermined temperature upon an overload of the motor, is provided at a predetermined distance between the resistance unit and a terminal.
