Title: High frequency amplifier circuit
Inventor: MIYAZAKI SHINICHI
IPC: H04B3/04
Filed: 1990-01-17
Abstract: PURPOSE:To save useless power consumption by controlling the bias voltage of a final stage high frequency transistor(TR) to obtain a proper gain. CONSTITUTION:A control voltage detection section 11 detects the voltage of a power supply from a power supply section 6 to a final stage high frequency amplifier section 1 and outputs a control signal to a bias voltage control section 12 to increase the gain of the final stage high frequency TR 2 when the voltage is higher than a predetermined voltage and to decrease the gain when it is lower conversely. The bias voltage control section 12 uses the control signal from the control voltage detection section 11 to control the bias voltage inputted from a bias input terminal 10 to supply the result to the high frequency amplifier section 2. Thus, useless power consumption is reduced.

Title: Delay device and video signal processing unit using the delay device
Inventor: MATSUI HIDEAKI
IPC: H04N9/87
Filed: 1994-01-31
Abstract: PURPOSE:To obtain a device delaying a video signal for one horizontal synchronization period regardless of a trace speed by providing a variable frequency oscillator generating a control signal of a frequency delaying a reproduced luminance/chrominance signal by a period corresponding to one horizontal synchronization period based on a field frequency. CONSTITUTION:A video field whose frequency is fv is received from an input terminal 14, frequency-divided by 1/2 at a 1/2 frequency divider 19 of a computing element 15 and the result is given to a phase comparator 23. On the other hand, a control signal whose frequency is 2fsc' from a voltage controlled oscillator (VCO) 16 is given to a variable frequency divider 22 via a 1/455 frequency divider 21, in which the signal is frequency-divided into nearly a frequency fv/2 depending on a tape drive state and the result is given to a phase comparator 23. The comparator 23 compares the phases of the two signals and provides an output of a phase difference signal converted into a pulse width to a voltage converter 24. The converter 24 gives the voltage signal corresponding to the phase difference signal to the VCO 16. Thus, even in the high speed search of a VTR, the signal is delayed by the same time as a 1H period.

Title: Data receiving circuit
Inventor: WAKAYAMA YASUSHI
IPC: H04L29/08
Filed: 1988-01-18
Abstract: PURPOSE:To shorten the transferring time of a data signal to 1/2, and to make effective data processing work by alternately fetching every bit of the input data signal in synchronization with a transfer clock at the same frequencies as those of an action clock. CONSTITUTION:The speed of a data signal D supplied to input terminals 1 and 3 and that of a transfer clock TCK are doubled. In a first data memory circuit 6a, while a signal TCK/2 of an enable terminal INE is at a low level, a signal Da of the data input terminal D is fetched in synchronization with the rise of the transfer clock TCK, and it is outputted to an output terminal Q. In a second data memory circuit 6b, while the signal TCK/2 of the enable terminal INE is at the high level, the signal Da of the data input terminal D is fetched in synchronization with the rise of the transfer clock TCK, and it is outputted to the output terminal Q. Thus, the speed of the signal is made twice faster than the ordinary speed, and the data signal at the same repeating frequencies as those of the action clock of itself can be surely received.

Filed: 1979-01-30
Abstract: PURPOSE: To efficiently separate non-magnetic metal by a method wherein magnetic repulsion coil is placed near the bottom face of transferring member, and current is supplied to the coil with a period that relates to the speed of transferring member.  
     CONSTITUTION: Transferring member 1 (such as belt conveyor) is located higher at the inlet for waste material (left) and lower at the outlet (right). A magnetic repulsive coil 2 having magnetic axis perpendicular to the surface of the member 1 is placed near the bottom surface of the member 1. A capacitor 3 is charged by AC supply 9 through rectifier 4. Capacitor charge is applied momentarily to the coil 2 by starter 5 that is actuated by speed signal generator 10 that connects to drive mechanism of member 1. This causes the coil 2 to generate magnetic pulse. As a result, non-magnetic metal is ejected, near outlet of member 1, from waste material charged from the vibrating feeder 6 (waste consisting of paper, plastic, alminum can, etc., from which magnetic metal is removed). The ejected non-magnetic metal  is collected in container 8, and non metal is contained in container 7, so that both  are separated each other.

Title: Bath device with hot-water supplier
Inventor: KITAGAWA KUNIYOSHI
IPC: F24H1/00
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To make the coming off of a cap accurately detectable. SOLUTION: When a bath device detects that the temperature detected by means of a thermistor drops 3 deg.C from a set temperature in S1, the device replenishes hot water to a bathtub by opening solenoid valve installed to a branch pipe for the bathtub in S2 and igniting a burner in S3. When it is confirmed that one minute has elapsed after the hot-water replenishment is started in S4, whether or not the temperature T2 detected by means of the thermistor rises at least 5 deg.C from the set temperature Ts is discriminated in S5. When the temperature rise is detected, the hot-water replenishment is continued until it is confirmed that the hot water reaches a prescribed flow rate by discriminating that a cap is at its proper position in S6. When the temperature rise is not detected, the hot-water replenishment is stopped by discriminating that the cap is not at its proper position.
