Title: Device for laying cable inside indoor pipe
Inventor: ETO YOSHIAKI
IPC: H02G1/08
Filed: 1992-08-25
Abstract: PURPOSE:To pass a cable powerfully inside an indoor pipe even if deposits such as rust, detergent, etc., or an installed cable exist inside an indoor pipe by passing a wire having rigidity inside the indoor pipe by specified constitution. CONSTITUTION:This is equipped with cable guide wire catching rollers 6a and 6b freely of reciprocation for sending out or returning a cable guide wire 4 having rigidity, catching it between themselves and cable guide wire catching driven rollers 7a and 7b opposite in phase. Moreover, this is equipped with a reversible motor 2 freely of normal and reverse rotation and a motion transmitting and converting mechanism which transmits and converts only the one- way rotation of the rotating motion of this reversible motor 2 to the reciprocating rotation of the driving cable guide wire catching rollers 6a and 6b. What is more, this is equipped with a flexible guide tube 5 which guides the cable guide wire 4 to the pipe port of the indoor pipe. Hereby, it becomes possible to lay a cable guide wire 4 even in the indoor pipe being impossible of cable guide by input.

Title: Power amplifier
Inventor: KATO KENJI
IPC: H03F1/02
Filed: 1986-09-26
Abstract: PURPOSE:To allow a source voltage to vary following up an output voltage and to reduce the power loss of an output stage by supplying an output-stage amplifier with a plus source voltage and a minus source voltage which have a specific voltage difference from the output voltage of a source voltage output part. CONSTITUTION:When an input signal ein is zero, the current signal of a preamplifier 1 is zero and the output voltage Eout of a power amplifier is zero. At this time, source voltages VCC and VEE have reference values Vref1 and Vref2 of pulse width modulator(PWM) controllers 4 and 5. Here, when a plus input signal (ein) is inputted, a current signal IB is generated and a load current Iout flows, so that the output voltage of the power amplifier drops. Consequently, the voltage between the C and E of a transistor Tr1 rises. The PWM controller 4 outputs a output pulse with narrow pulse width so as to set the rising voltage to the reference value Vref1, so that the source voltage VCC drops.
