Title: Switching power supply
Inventor: YASUMURA MASAYUKI
IPC: G05F1/38
Filed: 1991-05-01
Abstract: PURPOSE:To suppress high frequency distortion of commercial power supply by constituting an active smoothing filter of a smoothing circuit comprising a low capacity capacitor and a resonance frequency control resonant converter circuit. CONSTITUTION:Since a smoothing capacitor 3 connected with a full-wave rectifying circuit 2 has low capacity, DC output contains a ripple of frequency twice that of commercial power supply. A switching power supply system comprising a fixed resonance frequency control resonant converter circuit 4 inverts the DC output voltage to an AC voltage and high frequency sine wave operation takes place to feed an AC voltage, containing a component of twice frequency that of commercial power supply, through the primary and secondary windings N1, N2 of an AC/DC power supply regulation transformer 7 to a rectifying/ smoothing circuit 8 comprising an electrolytic capacitor. A control circuit 9 controls the control current of the control winding of the AC/DC power supply regulation transformer so that the average value of the DC voltage containing twice frequency component will be constant.

Title: Width compressing machine
Inventor: HEIKO KENJI
IPC: B21B1/02
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To take out the max. effect of uniforming deformation by arranging a pair of vibrating means opposing to the compressive direction, driving the vibrating means respectively at an approximately opposite phase and imparting forced vibration for repeating increase and decrease of rolling load to a material. SOLUTION: By respectively driving the vibrating means 2, 2' at an opposite phase, the forced vibration for repeating the increase and decrease of compressive load to the material is imparted. Consequently, the displacement in the middle part of the material is canceled and becomes zero. Furthermore, when vibrating frequency is taken as the primary resonance frequency in the compressive direction of the material, the strain in the middle part of the material is maximized. Consequently, plastic deformation reaches the middle part of the material and the deformation is uniformed as compared to at the time of static compression shown by a fine line. Furthermore, when the width dimension of the material is expressed by L, Young's modulus by E and the density by ρ, it is desirable to change vibrating frequency (f) at this time to (f)=(√(E/ρ))/2L'.

Title: Motor control circuit
Inventor: FUJII SHOZO
IPC: B41J29/38
Filed: 1985-06-12
Abstract: PURPOSE:To prevent a DC motor from heating and brushes from deteriorating, by switching the power gain of a power supply circuit to a low gain at initial position setting time. CONSTITUTION:A controller 5 outputs a speed command of direction A, a rotating direction command and a gain switching command, and closes a switch element 8. Thus, a speed deviation signal generator 6 supplies a speed deviation signal through an amplifier 11 to a power supply unit 12. When the projection 1a of a movable member 1 contacts a stopping lever 2, a DC motor 3 becomes a forcibly stopping state. Since the gain of the amplifier 11 drops at this time, a small current flows through the motor 3. When the fact that the motor 3 is in the forcibly stopping state is detected, the motor is moved to the initial position to be positioned. Thus, it can prevent the motor from overheating and brushes from deteriorating.

Abstract: PURPOSE:To increase the recording capacity of an optical disk by giving different thermal conductivity in a circumferential direction and the radial direction of a recording section so as to reduce the recording effect of a pit onto adjacent tracks remarkably. CONSTITUTION:The anisotropy of the thermal conductivity is given in the circumferential direction and the radial direction of a recording section.
