Title: Fluorescent screen of cathode-ray tube for color display
Inventor: OKABE SHUNJI
IPC: H01J29/32
Filed: 1985-06-10
Abstract: PURPOSE:To improve brightness, by forming a phosphor layer in two layers structure, and forming a phosphor layer common to the three color dots in the first layer and a phosphor layer with different color tones of three colors in the second layer. CONSTITUTION:The first phosphor layer 3 common to the three color phosphor dots is formed over the surface of a panel 1, over which, blue, green, and red phosphor dots 4 to 6 are formed. In this case, 2 in the figure is a black matrix and 7 is an aluminum layer. Since a phosphor layer is formed in the first layer to make the inner surface of the panel uneven, and three color phosphor dot patterns are formed thereover, strength of adhesion is so large that drops of phosphor dots can be prevented, even though an optimum membrane thickness is applied to get a maximum brightness. Furthermore, since the phosphor layer in the first layer is common to three colors, the screen can be formed with no shado mask.

Title: Direct current power supply unit
Inventor: SHIMOKAWA SADAJI
IPC: G05F3/06
Filed: 1979-09-28
Abstract: PURPOSE: To make it possible to vary the output with a comparatively simple constitution, by inserting a rectifier to the primary side of the transformer and by connecting a control switch in parallel to this rectifier, in the DC power supply unit which can vary the output in respect to DC.  
     CONSTITUTION: A rectifier, for example, input control diode D 2  is inserted to the primary side of ferro-resonance transformer T, and switch SW 1  is connected in parallel to diode D 2 . If switch SW 1  is closed at the normal time, the normal input voltage is applied to transformer T, and the voltage of a waveform determined by the winding ratio of the primary and the secondary windings is induced in the secondary side. Consequently, the DC output voltage obtained by rectifying this voltage by high-voltage rectifying diode D 1  is proportional to the amplitude. Here, when switch SW 1  is opened, a half-wave input is applied to transformer T through diode D 2  to excite it in DC. As a result, transformer T generates single magnetic deflection, and a DC output increased or reduced in steps is obtained in the secondary side.
