Title: Forward/reverse rotating apparatus for reluctance type motor
Inventor: BAN ITSUKI
IPC: H02P7/00
Filed: 1990-05-15
Abstract: PURPOSE:To suppress mechanical and electrical noise and to simplify the structure of a DC power supply by sustaining the armature current at a set value corresponding to a load, regardless of applied voltage, when the applied voltage of motor exceeds the set value. CONSTITUTION:When the output of an absolute value circuit 41 exceeds the voltage of a reference voltage source 46 due to increase of exciting current, outputs from an operational amplifier 46a and an AND gate 15a go Low to disable transistors 22a, 22b. Consequently, a current flows through a diode 23b, a capacitor 39, a power supply and a diode 23a to return magnetic energy back to the power supply. Upon droppage below a predetermined level, output of the operational amplifier 46a goes High to conduct the transistors 22a, 22b thus increasing the exciting current. Upon increase to the set value, output of the operational amplifier 46a goes Low again to disable the transistors 22a, 22b.

Abstract: PURPOSE:To write a data at a prescribed position always without being affected by the nonuniform rotation of a disk by setting a write clock prescribed-fold as much as the frequency of a servo signal. CONSTITUTION:An N frequency dividing means 20 is provided to output the frequency of the servo signal generated by a servo signal generating means 12 while dividing it at an integer N, and an M multiplying means 22 is provided to output the output of the means 20 as the write clock while multiplying it with an integer M. Then, a ratio setting means 24 is provided to set the integers M and N respectively to the said N frequency dividing means 20 and the means 22 corresponding to the write position in a radial direction on a magnetic disk medium 10. The write clock to be outputted from the means 22 multiplies the frequency of the servo signal by the integer M/N and by suitably applying this M/N, the plural kinds of frequencies required for a ZBR system can be obtained. Further, since these signals are synchronized to the rotation of the medium 10, the write position is not fluctuated.

Filed: 1980-09-10
Abstract: PURPOSE: To decrease the defects produced in a brazed part and to obtain the sound brazed part by controlling the pressure of a brazing atmosphere.  
     CONSTITUTION: While the degree of vacuum in a furnace 11 is measured with a vacuum gage 12, the displacement of a vacuum pump 13 and the gas introduction amt. of a gas introducing valve 14 are regulated to regulate the pressure in the furnace 11. The inside of the furnace is heated up to a brazing material molting temp. in a low pressure (high degree of vacuum) atmosphere, and the heating is maintained for a certain time (until the brazing filler metal melts and runs to the joint). Thence, while the temp. is held maintained high, the heating is maintained for a certain time (until pores shrink) under the atmospheric pressure relatively higher (low degree of vacuum) than the above-mentioned pressure. According to this method, the volume of the pores produced in the brazing part decreases considerably in inverse proportion to the atmospheric pressure.
