摘要： An indigo compound is prepared from a corresponding indole compound which is unsubstituted at the 2- and 3- positions. The indole compound and an organic hydroperoxide are reacted in the presence of a catalyst which is a metal selected from the group consisting of the metals of Groups 4, 5 and 6 of the periodic table or a compound of the metal. The reaction is conducted while taking out water from a reaction system, said water being that introduced in the reaction system or formed during the reaction, or while controlling the amount of water, which is introduced in the reaction system, at a level not greater than 1 mole per mole of the indole compound.

摘要： A television sound receiver includes an input terminal for selectively receiving a television sound signal from one or more broadcasting stations and a home television apparatus, a tuner, having a local oscillator, connected to the input terminal, an intercarrier sound demodulating circuit connected to the tuner, a split-carrier sound demodulating circuit, including a limiter amplifier, connected to the tuner, a sound signal output terminal, and switching circuitry for selectively and operatively connecting the intercarrier or split-carrier sound demodulating circuit between the tuner and sound signal output terminal. Additionally the receiver includes an error detector connected to the split-carrier sound demodulating circuit for detecting the frequency error of the tuner local oscillator and a first operational circuit responsive to the output signal from the error detector which produces a first operational output signal whereby the output signal therefrom activates the switching circuitry such that the split-carrier sound demodulating circuit is operatively connected between the tuner and the sound signal output terminal when the output signal from the error detector is less than a predetermined level. Control circuitry is provided which supplies a signal to activate the switching circuitry such that the intercarrier sound demodulating circuit is operatively connected between the tuner and sound signal output terminal whenever the home television apparatus is operatively connected to the input terminal. A second operational circuit is also provided which is responsive to output signals from a pair of level detectors which are connected to the limiter amplifier. An output signal supplied from the second operational circuit activates the switching circuitry such that the intercarrier sound demodulating circuit is operatively connected between the tuner and the sound signal output terminal when the output signals from the level detectors are below a predetermined value.

摘要： An oscillating circuit provides first and second reference signals having a phase difference of 90.degree. with respect to each other. The oscillating circuit includes an oscillator providing the first reference signal at an output thereof, a voltage-to-current converting circuit, which may incorporate a common-base transistor, and a capacitor connected between the output of the oscillator and an input of the converting circuit. The output of the converting circuit then provides the second reference signal which differs in phase by 90.degree. from the first reference signal. The oscillator may include differentially connected transistors and an LC resonant circuit.
