Title: Modulating circuit of pulse width
Inventor: YOKOYAMA KENJI
IPC: H03K7/08
Filed: 1982-01-29
Abstract: PURPOSE:To obtain a modulated output of small distortion with use of an ordinary carrier signal, by providing a comparator to compare the output signal of an amplifier and a carrier signal and a feedback circuit of said output signal. CONSTITUTION:A signal e3 always has the same potential as an audio signal ea due to the property of a negative feedback amplifier. A triangular wave of a cycle T is supplied in the form of a carrier signal ec, and it is supposed that the signal ea at an earth level. Both absolute values are equal to Vc/R2. A triangular wave e4 which is decided by the value of a capacitor 12 and its charge/ discharge current i3 is obtained at an output terminal of an operational amplifier 8. The signal e4 is compared with the signal ec through a comparator 9, and the signal e2 is negatively fed back. The cycle of each signal is equal to the cycle T of a signal e0. Therefore the signal e2 is turned into a pulse signal having a cycle T and the duty ratio of 1. In case, the signal ea is higher or lower than the earth level, the pulse width varies between high and low level periods. The sufficient negative feedback is applied to the signal ea to reduce the distortion. An effect of distortion is eliminated by the signal e4 for the signal ec.

Abstract: PURPOSE:To join both steel pipes in a good shape and good quality without causing a zinc inclusion and spark by heating the steel pipe whose one part at least is zinc plated each other by electrifying within the range of a specific time with pressurizing in a specific pressure range and feeding in at proper speed. CONSTITUTION:The steel pipes 1, 2 for a heat exchanger, for instance, whose one part at least is zinc plated are fed in slowly in the range of 2-10mm/sec by heating them by passing the current of 1V1,000A for 0.2-1.2sec, for instance, with giving the pressurizing force of 10-40kgf by clamping with electrodes 6, 7 respectively.
