Abstract: PURPOSE:To silence a propagated sound wave from an air-conditioner completely at an opening of a sound shield wall by installing a speaker in a room surrounded by the sound shield wall and mounting an error microphone to an opening of the opening part. CONSTITUTION:A speaker 34 is fitted to an inner wall face of a sound shield wall 10 and its sound wave radiation front 34a is directed toward a ceiling of the sound shield wall 10. An error microphone 34 mounted in the middle of ventilators 12, 14 is not affected by the state of a sound field in an outer space but detects only the propagation sound wave radiating from an air- conditioner 28. Thus, the sound wave radiating from the speaker 34 is controlled based on each output signal from the error microphone 32 and a sensor microphone 30, then a sound pressure silencing the propagation sound wave is decided at the position of the error microphone 32, that is, in the middle of the ventilators 12, 14.

Title: Short circuit detection circuit
Inventor: KOJIMA AKIHIRO
IPC: H04B3/46
Filed: 1995-03-30
Abstract: PURPOSE: To protect a machine against breakdown due to short circuit of a line connecting the machine body and an auxiliary machine. CONSTITUTION: A short circuit detection Zener diode Zd has a Zener voltage lower than that of a short circuit detection voltage setting Zener diode Z inserted between a power supply circuit 8 and a DC power supply circuit P. When the line is not short-circuited, the Zener diode Zd is conducted to turn a line detection transistor Tr2 and a power supply transistor Tr1 ON thus feeding power from the DC power supply circuit P to the power supply circuit 8. When the line is short-circuited, the Zener diode Zd is not conducted and the line detection transistor Tr2 and the power supply transistor Tr1 are turned ON thus feeding no power from the DC power supply circuit P to the power supply circuit 8. With such circuitry, overcurrent caused by short circuit is not loaded on a short circuit detection circuit.

Title: Impedance variable circuit
Inventor: MATSUNAGA KOICHI
IPC: H03H11/24
Filed: 1988-03-28
Abstract: PURPOSE:To form a circuit with less nonlinear characteristic even to a low power supply voltage by providing 2n-set in total of current mirror circuits and variable current sources, connecting a 2r-th and (2r+1)-th collectors of 2n sets of PNP transistors(TR) and connecting an output terminal to the collector of a 2n-th PNP TR. CONSTITUTION:Denoting a current flowing to a TR 5 and a diode 6-1 as I1, then the collector current of TRs 1-1-1-4 is equal to the I1 because they are configurates as current mirror circuits. The AC voltage amplitude V at a variable current source terminal 10 with an AC current (i) flowing thereto is caused due to a difference between a base-emitter voltage VBE5 of the TR 5 and base- emitter voltages VBE6-1-VBE6-7 of diodes 6-1-6-7. Then the resistance R0 of an impedance variable circuit A is expressed as R0=V/i. Thus, the linearity is much improved than a conventional circuit with number of diodes connected in series. With number of linearity kept equal conversely, number of diodes connected in series is decreased.
