Abstract: PURPOSE:To increase the efficiency of a power amplifier by modulating pulse width on the basis of a synchronizing signal extracted from a video signal or a picture itself and changing the power voltage to be applied to the power amplifier according to the existance of the synchronizing signal or the picture. CONSTITUTION:A synchronizing separator circuit 21 extracts a synchronizing signal from a video input and sends the signal to both a multiplying circuit 22 and a controller 28.

The pulse width modulator 23 modulates the pulse width of a subscarrier sent from the multiplying circuit 22 by the picture bias or synchronizing bias and applies DC current corresponding to the pulse width to the base of a transistor (TR)24. Thus, the connection period of the TR24 is controlled, stabilizing the output voltage from a rectifier power source 13 and applying the output voltage to a power amplifier 12 through a smoothing circuit.

Filed: 1978-11-22
Abstract: PURPOSE: To prepare the title fine particles, useful for the suspension polymerization or copolymerization of polymerizable monomers, and dispersible easily and homogeneously in water, by precipitating an organic peroxide from an organic solvent in the presence of a water-soluble polymer.  
     CONSTITUTION: An organic peroxide (e.g. diacyl peroxide) is dissolved in an organic solvent such as pentane and hexane. 0.1W10 Parts, based on 1 part of the peroxide, of a water-soluble polymer (e.g. celluosic water-soluble polymer) is added to the solution, and the solvent is evaporated or distilled off at a temperature below the heat decomposition temperature of the peroxide leaving the objective fine particles of the organic peroxide. Since the particles can be dispersed uniformly in water, and dissolved in the droplets of the polymerizable monomer, the productivity of the polymer can be remarkably improved. The physical properties and processability of the resulting polymer are extremely high because of the absence of solvents other than water in the preparation of the polymer.
