Title: Talking current control system of private branch exchange
Inventor: UNOSAWA MITSUO
IPC: H04Q3/58
Filed: 1979-04-02
Abstract: PURPOSE:To make it possible to maintain call attenuation at its minimum by providing a common unit with the extension line resistance measuring circuit of a private branch exchange and then by controlling a talking current, supplied to an extension telephone, by the measured value. CONSTITUTION:An incoming call, arriving from a main wire, is led to main-wire trunk CBWT, and at the same time, displayed on attendant console ATT through the operation of central processor CC. Once an answer is made by ATT, switch SW forms a channel between the main wire and an operator and extension telephone TEL is connected to calling signal trunk RGT by pushing a desired extension number of ATT, thereby sending a calling signal to TEL. When the extension answers it, a line resistance value via the extension telephone is measured by line  resistance measuring circuit LRSM in RGT. Unit CC connects CBWT to TEL and  corresponding to the measured resistance value, a telephone current control relay is  put into operation to send the best talking current to TEL. Consequently, the calling attenuation can be suppressed to its minimum without refrence to the extension  telephone.

Title: Method of controlling reactive power compensation type cyclo-converter
Inventor: TANAKA SHIGERU
IPC: H02M5/27
Filed: 1980-03-29
Abstract: PURPOSE:To control a cyclo-converter without wasteful time upon detection of a delayed reactive power from the output current of the converters in positive and negative groups without using an expensive transformer nor a current transformer by controlling the phase control signal of the cyclo-converter by detecting the reactive power. CONSTITUTION:A phase advance capacitor C is connected to the power terminal of a circulating current type cyclo-converter CC, and a circulating current is so controlled that delayed reactive power and the advanced reactive power of the phase advance capacitor may cancel each other. The delayed reactive power of the capacitor CC is detected from the output currrents from the positive group converter SS-P and the negative group converter SS-N to control the phase control signal of the capacitor CC. For example, the value of cos alpha of an arc control angle alpha is obtained from the output of an amplifier K2 for amplifying the deviation epsilon3 between the instructed value LL* and the detected value LL of the load current, and sin alpha is then obtained by the square, the addition and the development of the value of cos alpha. Further, the sum of the output currents of the SS-P, SS-N is multiplied thereby to obtain the delayed reactive power IREACT=(IP+IN).sin alpha, and the entire delayed reactive power QCC is obtained therefrom to control the converter.
