A magnetic-flux density distribution in a place in which the magnetic body 5 is situated is formed in such a way that, since the slit plate 4 is installed so as to be brought into close contact with the permanent magnet 2, the magnetic body 5 is subjected to a thrust so as to be moved to a position in which a magnetic flux density becomes maximum, and that the magnetic body is moved to the position so as to be stabilized. Consequently, the exciting coil 3 can be held in a prescribed stop position.  Thereby, without supplying a current to the exciting coil 3 (a moving part), the exciting coil 3 can be held in a prescribed position, and an effect to reduce a power consumption is obtained.

Title: Cooling device and printing device using it
Inventor: HIRANO YOSHIAKI
IPC: H02P7/288
Filed: 1993-12-20
Abstract: PURPOSE:To provide a cooling device for preventing an unneeded power consumption by controlling the rotary speed of a fan based on the temperature of an object to be cooled and then a printing device using the cooling device. CONSTITUTION:The output of a differential amplifier 3 is obtained based on the difference in the output voltage between a thermocouple 1 and a reference voltage generator 2. The output is input to a comparator 8 and the output of the comparator 8 is input to a transistor 11 for driving a fan 9 via a resistor 14. An FG 10 for generating a voltage proportional to the rotary speed of a fan 9 is connected to the fan 9 and the output voltage is divided by resistors 12 and 13 for dropping to a proper voltage value and then is input to the comparator 8. A diode 15 prevents an inverse bias voltage from being applied to the transistor 11. With the above configuration, when the output voltage value of the thermocouple 1 is lower than the reference voltage value, the fan 9 is stopped. On the other hand, when the output voltage value of the thermocouple 1 becomes higher than the reference voltage value, the rotary speed of the fan 9 increases in proportion to temperature.
