Title: Operation check device of anti-skid control system
Inventor: MATSUDA TOSHIROU
IPC: B60T8/88
Filed: 1981-07-08
Abstract: PURPOSE:To check a driving circuit of an oil hydraulic actuator without causing the necessity for operating the actuator, by checking the driving circuit of the actuator with a current value less than its operating current value. CONSTITUTION:An anti-skid control circuit 11 drives a solenoid 12 thorugh transistors Tr1-Tr4 on the basis of a signal of a sensor 10. Now for check work, if an operation check circuit 13 is operated, the circuit 13 feeds a dummy signal to the control circuit 11, while opens a power source relay contact 14 to prevent the solenoid 12 from being driven. Then each transistor Tr1-Tr4 is electrically conducted through a resistor 15, and a NOR gate 16 turns on a display lamp 17 through a transistor Tr5 except when each transistor Tr1-Tr4 is all normal. In this way, the solenoid is not operated by opening of the contact 14, and a driving circuit is not performed reduction operation at check work, thus each driving transistor Tr1-Tr4 can be checked.

Title: Preventing method of irregular magnetization of transformer for inverter
Inventor: KOUNO HITOSHI
IPC: H02M7/537
Filed: 1984-05-24
Abstract: PURPOSE:To remove the positive or negative deviation of the output voltage of an inverter by superposing a signal integrated from the output detected from a winding on the operation signal of an inverter switching element in response to the polarity of a winding current. CONSTITUTION:A current detector 31 detects the positive side of an I1 flowed to the primary winding 7a, a current detector 32 detects the negative side, the detected output S1 of the former is added to an adding point 33, and the detected output S2 of the latter is subtracted. The output of the point 33 is applied to the input terminal of an integrator 34, and the integrated value SI of the outputs S1, S2 is output. The value S1 is supplied to a switching element 35 which becomes ON when the current I1 is negative and OFF when positive. On the contrary, it is supplied also to a switching element 36 at the reverse time. Thus, the AC output from the inverter does not contain the DC component to preent a transformer from irregularly magnetizing.

Title: Optical lens-driving apparatus
Inventor: UEDA YASUO
IPC: G11B7/135
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To uniformly transmit heat generated from a coil to the periphery of an objective lens and enable signals of an optical disk to be read in a stable state, by providing the objective lens of a synthetic resin, a synthetic resin holder holding the objective lens and a driving means driving the holder, and arranging a metallic part in the periphery of the objective lens. SOLUTION: Heat is generated when a current is fed to a focus coil 3 and tracking coils 4a, 4b directly wound to a synthetic resin holder 2 holding a synthetic resin objective lens 1. If a metallic part 17 is arranged in the periphery of the synthetic resin objective lens 1, the metallic part 17 transmits the heat uniformly to the periphery of the synthetic resin objective lens 1, and accordingly restricts a deformation of the synthetic resin objective lens 1. Moreover, a spot shape of a laser can be greatly refrained from being deformed. Since the metallic part 17 uses a light-weight aluminum member, the effect is achieved although a weight change is hardly given rise to at a movable part. The apparatus has good processability and is inexpensive.
