Title: Current limiting reactor
Inventor: ARINOBU HIROYUKI
IPC: H01F7/16
Filed: 1982-05-31
Abstract: PURPOSE:To easily make a reactor adaptable to various rated currents such that the impedance is reduced during feeding of the rated current and increased at the time of occurrence of an excessive current, by a construction wherein a plunger is disposed to be inserted into or drawn out from a coil, and the plunger is attracted into the coil by a magnetic force caused on the coil at the time of short-circuit and excessive load. CONSTITUTION:A current limiting reactor is connected in series to wiring lines (not shown) through a terminal unit 19, and a coil 8 serves as an electric line element. The illustrated state represents the normal state where the rated current is fed. At this time, since the resilient force of the latch spring 22 over comes the total sum of the attraction force of the coil 8 for attracting a plunger 22 and the resilient force of a coil spring 28, the plunger 22 is held away from a coil bobbin 9. Thus, the current limiting reactor has an impedance value based on the hollow coil. This makes it possible to set the impedance relatively small for feeding of the rated current.

Abstract: PURPOSE:To prevent the overheating of power transistors by shunting the electric current which flows in continuation in the bases of the power transistors for opening and closing the ignition coil electric current in case of the opened state on the power source grounding side, to the grounded side by the operation of a diode for shunt. CONSTITUTION:During the time when the ignition signal 7a applied from an electronic distributing circuit 13 is '0', a transistor 7 is in OFF-state, and a power transistor 1 is turned-ON, and a high voltage is generated in the secondary winding by the cutting-off of the electric current in the primary winding 4 of an ignition coil.

Abstract: PURPOSE:To remarkably reduce a shaking in a lens barrel section and to employ for a portable video camera by operating a gain correcting means when a tilting operation is detected by a tilting operation detecting means, and by increasing and decreasing a relative ratio according to a relative angular velocity between the lens barrel section and a supporting body. CONSTITUTION:A titling start detecting means detects the start of the tilting operation from the fact that a relative angle thetah, or a synthetic value of the relative angle and a relative angular velocity is outside a prescribed range by a digital value P corresponding to the relative angle thetah of a lens barrel section 1 and a main body case 2 and a digital value V corresponding to the relative angular velocity. From the value of the digital value V corresponding to the relative angular velocity at that time, viewing a degree of a change of the digital value P corresponding to the relative angle at the next time, the synthetic ratio D is corrected. For instance, if V is the same code as P, the synthetic ratio D is made larger and a generating torque Tm of an actuator 3 is enlarged. Accordingly, almost following to an increase of the angle thetax of the main body case 2, an angle thetam of the lens barrel section 1 is increased and the collision therebetween can be prevented.
