Abstract: PURPOSE:To decide the quality of tracking with simple constitution and to perform muting immediately after starting reproduction, etc., at good timing, by extracting a signal component corresponding to the difference in frequency of a carrier signal and pilot signal, and comparing the sum of their signal levels with a preset voltage value. CONSTITUTION:A head switching signal inputted from a terminal 1 is inputted in a circulating frequency generator 2 and switch 18, and the generator 2 sends a carrier signal to a mixer 11. The output of a magnetic head 8 is supplied to an LPF10 where a pilot signal component is extracted from the output through a reproducing amplifier 9, then sent to the mixed 11 where the output is mixed with the carrier signal. The difference signal is subjected to envelope detection at detectors 14 and 15 after passing through BPFs 12 and 13 and outputs of the detectors 14 and 15 are supplied to a subtractor 16 and adder 21. The quantity of the positional deviation of the magnetic head 8 from a track is obtained from the output of the subtractor 16. The output of the adder 21 is sent to a comparator 23 where the output is compared with a prescribed value through an LPF22 and the quality of the tracking is decided from the scale of the difference output of the comparator and countermeasure, such as muting, etc., is taken.

IPC: H02M3/28
Filed: 1986-05-09
Abstract: PURPOSE:To prevent an abnormal current due to the short-circuit of a load with a simple configuration by providing the bias power of an error amplifier depending upon an output voltage. CONSTITUTION:When an output voltage rises due to the rise of a DC power source 13 or the fall of a load 20, its output voltage is compared and amplified by an error amplifier 23 to enhance the output voltage of the amplifier 23, thereby raising the impedance as seen from a rectifier 22. Accordingly, an equivalent circuit in which the output impedance of the amplifier 23 impedanceconverted by a transformer 21 is inserted in series is provided between a base winding 17 and the base terminal of a transistor 16 to reduce its output voltage. The bias power source of the amplifier 23 is supplied from the output voltage. Thus, when the output is short-circuited, a current flowing to a transformer 24 is eliminated to reduce its output voltage. thereby obviating the abnormal increase of an output current.

Title: Windshield wiper controller
Inventor: TANAKA TAKAHIKO
IPC: B60S1/18
Filed: 1986-05-12
Abstract: PURPOSE:To simplify the control circuit structure of a windshield wiper, by performing a changeover making a housing function valid or invalid with a miniature switch consisting of one contact small in contact rating. CONSTITUTION:A signal out of a circuit having a housing cancel switch 6 is inputted into a microcomputer 4 making a windshield wiper perform various operations. When a winter position is selected by this housing cancel switch 6, a wiper blade is stopped at an intermittent stop position by a signal out of the microcomputer 4, and it is made so as not to be moved up to a wiper housing position. On the other hand, if the housing cancel switch 6 has selected a summer position, the microcomputer is operated so as to stop the wiper at the wiper housing position. With this constitution, such nonconformity that the wiper comes to inoperative due to snow or the like because the wiper is left in a state of being housed at the winter season is preventable.

Title: Shut-off valve with suction cylinder
Inventor: SAKAI YASUSADA
IPC: F16K17/36
Filed: 1981-07-11
Abstract: PURPOSE:To enable to shut off gas flow inside a container valve even if the cylinder body is damaged, by employing such an arrangement that a female screw is designed to slide in the opposite direction to the gas flow. CONSTITUTION:When the gas container falls by a shock or some other reason and a female screw 32 comes out, an inner plunger 13 connected to a control pin 11 by the force of a metal piece 23 is drawn out and a ball fits into a recess formed in a retainer 17. At the same time, a plunger 2 is pushed back by the force of a spring 14. Resultantly, a valve provided at the top comes into tight contact with a face 6, so that the gas 31 flow can be isolated from gas 30. After the gas flow is shut off, the female screw 32 is retracted inwards by the internal pressure of a down-stream high-pressure hose or the like. However, since a jig for the control pin 11 and a coil 18 is slid in a hole formed in the metal piece 23, the valve is not opened, so that the supply of gas, oil or the like can be stopped in a reliable manner.
