IPC: H01H13/14
Filed: 1994-04-22
Abstract: PURPOSE:To reduce an overall height, to provide a comparatively simple structure, and to effect manufacture at a low cost by a method wherein a resin frame and a key top are intercoupled through a link shaft.

Title: Amplifier circuit for deflection circuit
Inventor: MASHITA SHIGEAKI
IPC: H04N3/16
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption more than that of a conventional circuit by providing a transistor(TR), a 2nd diode, and a 2nd resistor whose resistance is higher than that of a 1st resistor, in addition to a pumpup circuit, to the amplifier circuit. SOLUTION: A charge time is determined by the time constant of a pumpup capacitor PC11 and a 1st resistor R11. Since the resistance of the 1st resistor R11 is small, the time constant is not increased, and, hence, it is possible to avoid the situation in which the time required for charge/discharge is extended and the increase/decrease in a power supply voltage cannot follow the increase/ decrease in an output voltage is taking place. Furthermore, discharged through a discharging route during a blanking period, and in this case, a 2nd resistor R12 directly connected to a positive power supply +Vcc has a higher resistance than that of the 1st resistor R11, so that the current flowing therein is small. Moreover, a TR11 is nonconductive and no current flows in the 1st resistor R11, and hence the power consumption due to the current flowing in both resistors 11, 12 can be reduced.

Title: Data detecting circuit of television receiver or video tape recorder in program rating measurement system
Inventor: WATABE FUMIO
IPC: H04H1/00
Filed: 1983-06-17
Abstract: PURPOSE:To discriminate an accurate program rating channel in using a television receiver as a monitor via a high frequency output signal of a video tape recorder by adopting the comparison of audio signals when a channel cannot be discriminated through the comparison of sound intermediate frequency signals. CONSTITUTION:After an output signal of a tuner 3 is demodulated into a composite signal by a video intermediate frequency amplification/video detecting circuit 4, only a sound intermediate frequency signal is extracted from a sound intermediate frequency amplifier circuit 5. On the other hand, a detector S1 detects the sound intermediate frequency signal from a reception circuit of the VTR and amplifies it to a required level by a sound intermediate frequency amplifier circuit 10. Then, a signal of both paths of the amplifier circuits 5, 10 is frequency-divided respectively by frequency dividers 6, 11 and inputted to a comparator circuit 7. Then the comparator circuit 7 compares the voltage of both signals b, d so as to discriminate whether the both are signals of an identical broadcast or not. A counter of a data encoder 15 conducts continuously the count while channels of the tuner 3 and received by the VTR are different, a generated voltage of a tuning voltage generating circuit 2 is changed according to the preset order and this is continued until the channel received by the tuner 3 is coincident with the received channel of the video tape recorder VTR.

Abstract: PURPOSE:To eliminate the projecting-out of a foamable wedge mounted in the opened part of a semiclosed slot from the opened part when the wedge is heated and foamed by foaming and hardening the surface of the wedge by a laser beam and then heating the entirety when the wedgeis heated. CONSTITUTION:After a coil 4 is wound in a semiclosed slot 2 of a core 1, a foamable wedge 5 is inserted into the opened part of the slot.

Title: Device for controlling speed of motor
Inventor: UCHIDA RIKUO
IPC: H02P29/00
Filed: 1978-09-04
Abstract: PURPOSE: To control the speed of a motor in wide range with stable characteristic by providing a compensating circuit for varying the gain of a speed control loop by a detected speed signal.  
     CONSTITUTION: The output e 4  of a speed detector 2 is converted by an absolute value circuit 7a to an output e 5 , and a variable gain amplifier 7b alters the output e 5  as a parameter at a ratio of e 3 /e 2 . A speed deviation signal e 1  is applied through an amplifier 3 and the variable gain amplifier 7b to the firing circuit 4 of a thyristor amplifier 5 to thereby control the speed of a DC motor 1. Thus, the firing frequency ω of a speed control loop is altered by the different firing period of the phase control to allow the speed control loop gain K to respond to the motor control characteristic variation so that the product of K.ω may become constant to thereby restrict the control characteristic variations in the entire control region. Thus, the motor 1 is controlled at its speed in wide range with stable characteristic.
