Title: Manufacture of photoconductive cadmium sulfide particles
Inventor: SUZUKI KIYOSHI
IPC: G03G5/08
Filed: 1981-08-20
Abstract: PURPOSE:To obtain photoconductive cadmium sulfide particles suitable for electrophotography or the like, uniform in particle shape, and high in sensitivity, by introducing hydrogen sulfide into an ag. cadmium salt soln. containing chlorine not less than a specified amount to prepare CdS, and baking a mixture of this CdS and a flux. CONSTITUTION:A >=0.8mol/l chlorine solution is added to an aq. sol. of a water- soluble cadmium salt, such as cadmium sulfate or cadmium chloride, cadmium sulfide is produced by introducing hydrogen sulfide. A >=20wt% flux of cadmium chloride, sodium chloride, or the like is added to the obtained cadmium sulfide, and the mixture is baked at temp. higher than the m.p. of the flux by >=50 deg.C. Intended photoconductive cadmium sulfide particles are obtained by again baking said product. Since highly concd. chlorine is contained in the cadmium sulfide particles before the baking, chlorine is not perfectly removed in those particles after the baking, a proper amount of chlorine is left and contributes to enhancement of sensitivity of the cadmium sulfide particles.

At the reading-out under said state it is decided that an output OE reads out a correct data correctly. When the activation time is longer than the TRFO, the data is made incorrect and decided as a defective one. When the activation period TRFO of the changing point of a correctness and an incorrectness of the read out result is measured by changing the activation period TRF of a signal RFSH and reading out data without queue, the TRFO indicates the operating period TAR of the automatic refresh timer.

Abstract: PURPOSE:To perform the interruption of a parabolic antenna turning or to transfer to automatic tracking control by automatically stopping the further control of the parabolic antenna simultaneously with the capture of a satellite. CONSTITUTION:The output of the parabolic antenna ANT is inputted to a CS tuner 20, and a DC voltage in accordance with the strength of a reception signal can be obtained. In other words, the DC voltage represents signal level output, and it is compared with a reference voltage VREF by a comparator 22.
