Abstract: PURPOSE:To prevent the damage of an inverter by a method wherein the title device is provided with a means for detecting a current, which flows from a semiconductor breaker or a semiconductor switch to a load, and another means for detecting cross current between the semiconductor breaker and the semiconductor switch. CONSTITUTION:An AC current is generated by an inverter 4, inverting the output of a rectifier 2 or a battery 3, while power is supplied to the loads of respective systems through a thyristor breaker 5. As the preliminary means of an inverter circuit, the power is supplied to the loads through a thyristor switch 7 from a preliminary AC power source 6. The overcurrent OC1 of the loads is detected in a detector 9 by the output of a current transformer 8 for output current. A cross current OC2 between the thyristor breaker 5 and the thyristor switch 7 is detected in another detector 21 by the output of the current transformer 20 for the cross current. An interception selecting circuit 22 decides by the signals OC1, OC2 whether the overcurrent is on the side of a load or in the cross current and the thyristor breaker 5 or the thyrister switch 7 is put OFF by a switching control circuit 10. According to this method, power supply may be continued and the inverter 4 may be protected.

Abstract: PURPOSE:To detect the quality and sucking state of a part, by providing a vacuum pressure detecting part for distinguishing the vacuum pressure in a nozzle in plural stages at the sucking time of the part and distinguishing the quality and sucking state of the part as the stage difference of vacuum pressure. CONSTITUTION:When the quality and sucking state of a part are judged, a control part 7 indicates a vacuum pressure level range at every part shape becoming a comparing control. A nozzle 4 is once raised in vacuum pressure before the sucking of the part. Said vacuum pressure is distinguished in plural stages by a vacuum pressure detecting part 6 and the control part 7 confirms the stage of said vacuum pressure to judge whether the vacuum pressure in the nozzle is within a prescribed level range, that is, the nozzle is clogged with dust. As a result, when the vacuum pressure is judged to be normal, the part is sucked and, when said pressure is judged to be abnormal, sucking operation is stopped. By this method, the quality and sucking state of the part are detected.

IPC: G02B15/173
Filed: 1984-11-20
Abstract: PURPOSE:To maintain stable and superior image formation performance over a wide power variation range with simple constitution by providing a lens system of four-group constitution with the 2nd nonlinear moving lens which has a different movement track from a compensating lens group, and satisfying specific conditional expressions. CONSTITUTION:When the lens system of four-group constitution is varied in power from its wide-angle end W to its telephone end T, the 1st group G1 moves linearly toward the object side and the 2nd group G2 is fixed; and the 3rd group G3 moves nonlinearly for image plane compensation and the 4th group G4 moves as the 2nd nonlinear moving group. For example, an image-side lens group constituting an focal part has power betaR in the power variation range and the specific expressions I and II hold for the coefficient K of the quantity of movement of the lens group. The astigmatic and coma aberrations are therefore varied by varying the gap of the afocal part without varying the spherical aberration and the image formation performance which is stable and superior over the wide power variation range is obtained with the simple constitution.
