    Abstract: A phosphor consisting of a solid solution of a complex oxide of alkaline earth metals, aluminum and silicon, which contains oxides of the alkaline earth metals (Ca, Sr and Ba), aluminum and silicon as a host material, which is activated by divalent europium (Eu2 ), shows a bright luminescence spectrum in a wavelength region from near ultraviolet to bluish white, which depends upon the composition of the host material, through an excitation by ultraviolet rays or electron beams. The phosphor is utilized as a blue component for a fluorescent discharge lamp for copying, a flying spot tube, a storage tube or a Braun tube.

    Abstract: A circuit in which the voltage derived from a reference diode or silicon zener diode is fed back through an emitter-follower circuit to the base of a transistor and the constant current flowing through the emitter-collector circuit of the transistor is in turn applied to the reference diode so that such a stabilized output voltage as cannot be attained by the zener diode alone may be obtained.

    Abstract: A chrominance saturation control circuit to permit indirect or DC mode control of chrominance saturation. The connection between the chrominance saturation control knob in a television receiver and the chrominance saturation control circuit can be achieved through wiring which transmits only DC voltage. With this DC controlled chrominance saturation control, the television set may be made less susceptible to external interference compared to the case of using a shielded wiring for directly controlling the chrominance saturation.
