Title: High-frequency power conversion circuit
Inventor: MATSUMOTO NORIO
IPC: H02M3/24
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To maintain high power conversion efficiency for stable operation, even if input voltage fluctuates by comparing an output detection voltage with a reference one for controlling the frequency, and by providing two modes corresponding to the level of an input voltage as a reference voltage, when transferring to a transformer-driving circuit. SOLUTION: Output supplied to a load from a piezoelectric transformer is detected by a load current detection circuit 24. Also, a detection voltage is compared with a reference by an error amplifier 25, the difference is amplified, and an error voltage outputted from the error amplifier 25 is converted into frequency by an oscillator 26 for transferring to a transformer-driving circuit 21 via a switching-driving circuit 27. In this case, the reference voltage is made available in two ways by dividing a voltage V6 of a constant-voltage generator 29 with a resistor, and changing the division ratio with a transistor Tr2. More specifically, when the input signal of a terminal 31 is low, the transistor Tr2 is turned off, and the reference voltage is high, whereas when the input signal of the terminal 31 is high and the transistor Tr2 is turned on, the reference voltage becomes low.

Title: Voice switching circuit for loudspeaking telephone set
Inventor: TAKEYAMA HIROAKI
IPC: H04M1/60
Filed: 1985-02-25
Abstract: PURPOSE:To prevent a malfunction occurring due to peripheral noise in a regular time by detecting the average level of the output of the gain variable amplifier of a transmitting signal and controlling the amplification degree of the variable amplifier. CONSTITUTION:A transmitting input from a microphone 1 is inputted to a rectifying/smoothing circuit 6 and to an average level detection circuit 20 after an amplification by a gain variable amplifier 5a and the amplification degree of the amplifier 5a is controlled by a control signal Vg that is outputted from the circuit 20. In this case, when a transmitting input becomes larger by regular peripheral noise, the amplification degree of the amplifier 5a is lowered by that the average level which is detected at the circuit 20 is gradually increased and a transmitting level that is inputted to a comparator 13 is lowered by that a signal Vo which is inputted to the circuit 6 becomes smaller. Thus, the malfunction that keeps, for a long time, a transmitting state which is generated regularly by the peripheral noise is prevented.

Title: Distortion generating circuit
Inventor: FUJIKI YOSHINORI
IPC: H03F1/32
Filed: 1986-02-20
Abstract: PURPOSE:To obtain a distortion generator generating a prescribed distortion independently of a change in an input level and ambient temperature by applying a high frequency signal to a distortion generating element via a variable attenuator. CONSTITUTION:An anode of a diode 6 is connected to a variable attenuator 1 via an amplifier 7 to form one closed circuit. The diode 6 acts like a detector and a detection voltage 16 generated from the diode 6 is proportional to the quantity of distortion generated. Since the detection voltage 16 as above is impressed to the variable attenuator 1 via the amplifier 7, the variable attenuator 1 controls the detected voltage 101 to be a constant voltage. thus, the quantity of distortion proportional to the detection voltage is kept constant.
