Title: Stop control system for pulse motor
Inventor: HORITANI KEIICHI
IPC: H02P8/30
Filed: 1979-07-13
Abstract: PURPOSE:To check vibration at the stoppage of the subject motor by shifting to the intermittent excitation the exciting phase already excited immediately prior to the stop control of the pulse motor by the pulse signal so as to form a fixed detent from the single power source. CONSTITUTION:When the pulse motor is to be stopped, for example, in case the excitation signals S1 and S4 from the control circuit 17 are at a high level and those S2 and S3 are at a low level, the start/stop signal S/S is changed to the low level while the state of the excitation signals S1-S4 are kept in situ. As a result, the output of the OR gate 23 becomes the same as the pulse signal P. The pulse signal is applied to each base of the first and the fourth transistors 7 and 10 by way of the AND gates 19 and 22. Therefore, the pulse motor 1 forms a fixed detent through intermittent excitation of the exciting phases PH1 and PH4 by the pulse thereby checking vibration at the moment of the stoppage of the motor.

Abstract: PURPOSE: To enable long time operation of an electronic circuit, by dipping a plurality of metal balls having large specific heat per unit volume in refrigerant in a tank, decreasing the temperature of the metal balls, and cooling the electronic circuit at a specific temperature. CONSTITUTION: Heat is conducted from refrigerant to the outside air via an outer cylinder 4, and the refrigerant in a tank 3 is cooled. The refrigerant cools metal balls, and the temperatures of the refrigerant and the metal balls 5 are decreased. When an electronic circuit is operated and mounted components generate heat, the refrigerant in the tank 3 is made to flow to a cooling plate 2 by using a first pump 6 for circulating the refrigerant between the cooling plate 2 and the tank 3. Thus the electronic circuit 1 is cooled. When an operation condition that heat dissipation to the outside air is decreased continues for a long time, the temperature rise of the refrigerant is restrained by the heat dissipation of metal balls 5, so that the electronic circuit 1 is cooled at a specific temperature. Thereby the electronic circuit 1 can be operated for a long time.
