Title: Controller for induction motor
Inventor: NAKAMURA ATSUO
IPC: H02P27/08
Filed: 1988-07-26
Abstract: PURPOSE:To improve controlling characteristic at the time of voltage drop by so controlling that a motor terminal voltage becomes constant even if an AC input voltage is high or low. CONSTITUTION:A voltage control range of a PWM circuit 12 is generally specified by a control ratio determined by the amplitude ratio (A/B) of a triangular wave of a carrier signal to a control voltage signal. Then, the level of a 3-phase power supplied to a power source 1 is detected, and the control rate of the circuit 12 is altered at the time of turning ON the power source. Thus, the amplitude ratio (A/B) of the triangular wave to the control voltage signal is controlled inversely proportionally to the power source voltage. For example, in a low voltage range, the ratio (A/B) of the triangular wave to the control voltage signal is set to 1 or more, and the controlling characteristic at the time of voltage drop is improved.

Abstract: PURPOSE:To prevent superconducting characteristic from deteriorating by forming of a tunnel type Josephson element made of an oxide superconductor, a blocking layer formed by coating the surface with a metal hard to be coupled with oxygen, an insulator thin film layer formed thereon, and other superconductor electrode covering thereon. CONSTITUTION:In case that other superconductor 4 is approached through a thin insulating film 3 on an oxide superconductor 1 to form a Josephson element, when the film 3 is deposited on the superconductor 1, the characteristic of a superconductor electrode is remarkably deteriorated by the reaction with the superconductor 1 of the electrode material with the film 3, and a superconducting current is not observed, and a a resistance between both electrodes becomes very high. On the other hand, before the insulating film is deposited, metal hard to be oxidized, such as Au is used to form a blocking layer 2 on the superconductor 1, and the film 3 is then deposited. Then, it can prevent the superconductor 2 from reacting directly with the film 3. Accordingly, the superconducting characteristic of the electrode is not deteriorated. The blocking layer includes stable metal, such as Au, Pt, Ag, Cu which does not relatively form an oxide.

Filed: 1988-07-27
Abstract: PURPOSE:To obtain a sufficient regenerative braking force by delaying a starting timing of regenerative braking until the rotating speed of a motor becomes a predetermined value if a braking is conducted when a battery voltage drops to a predetermined value or less. CONSTITUTION:A switching signal output circuit 60 supplies a pulse signal having a predetermined duty ratio to a power transistor 56 when a motor current from a shunt resistor 52 becomes larger than a reference value VS1. On the other hand, a comparator 13 outputs a signal of H level when the rotating speed of a DC motor is larger than that VS3 of starting a regenerative braking. A comparator 14 outputs a signal of H level when the voltage of a battery 57 is larger than a reference value VS2. A NAND element 16 turns OFF an analog switch 19 when both the outputs of the comparators 13, 14 are not H level, thereby inhibiting the regenerative braking.
