Title: Step motor
Inventor: SUGIMOTO HIDEHIKO
IPC: H02K37/14
Filed: 1987-05-07
Abstract: PURPOSE:To improve effective utilization of flux and to reduce the size of step motor, by arranging high temperature super conductors in grooves of stator and rotor cores. CONSTITUTION:A step motor comprises a stator core 2 fixed to a stator frame, windings thereof, a rotor core 4a, permanent magnets arranged thereon, etc. Here, high-temperature superconductors 11 are arranged in grooves of the stator core 2 and the rotor core 4a. Since the high-temperature superconductors 11 exhibits diamagnetism, magnetic resistance between grooves of the stator core 2 and the rotor core 4a increases, and thereby almost all flux 7 passes through tooth sections when it passes through an air gap between the stator core 2 and the rotor core 4a. Consequently, difference of flux density between adjacent tooth sections and adjacent groove sections in the air gap increases, resulting in promotion of effective utilization of flux.

Filed: 1987-05-08
Abstract: PURPOSE:To improve the yield of an integrated circuit by giving a reference voltage to other input terminal of transistors(TRs) connected in series being components of the titled logic circuit so as to compensate the dispersion in the components. CONSTITUTION:A power voltage is applied between terminals VDD and VSS while a p-channel TR(p-FET)2 and an n-channel TR(n-FET)1 are connected in series. Moreover, a logic input is given to a gate VIN of the n-FET1 and a reference voltage is fed to a gate VV of the p-FET2. In this case, in varying the reference voltage, the threshold value of the logic circuit, the current consumption and the gain are changed. Thus, since the dispersion in the components is compensated, the yield of the integrated circuit is improved.

Abstract: PURPOSE:To enable a supervision over the operations of both a receiving high- frequency amplifier and receiving local oscillator, by inputting the output of the  receiving local oscillator to a mixer together with a received signal after two-wave  common amplification and then by monitoring the mixture electric current. CONSTITUTION:Received signal fr is inputted to coupler 12 via input circuit 11 and output fL of local oscillator 13 is also inputted to coupler 12, which outputs signals fr and fL. Those two signals are amplified in common by high-frequency amplifier 14 and then sent to coupler 15.
