Title: Shadow mask type color picture tube device
Inventor: NAKAMURA KOJI
IPC: H01J29/76
Filed: 1988-07-28
Abstract: PURPOSE:To decrease deterioration in color purity by exterting subdeflection on a beam deflected by means of a main deflector in such a way as to be put together with the varying direction of a hole position by injection of the electron beam of a shadow mask. CONSTITUTION:A main deflecting coil 11 is disposed in a corned section 12. A sub-deflector 20 is provided in the outer wall of a funnel 4 in the direction of an X axis. The deflector 20 is connected to a horizontal deflecting coil inside the main deflecting yoke 11 and supplies a part or all of its deflecting current so as to form magnetic field distribution in order to make an orbit of a beam. Accordingly, when the beam deflected by means of the yoke 11 so as to go substantially straight approaches a shadow mask 6 so as to enter within a sub-deflected range, it is bent in such a direction, for example, as to diminish a deflecting angle, and then goes straight outside the sub-deflected range. Therefore, if the varying direction of the hole position of the shadow mask by doming and a deflecting direction near the shadow mask of the beam are put together, any landing error can be prevented and deterioration in color purity can be decreased.

IPC: G06F1/00
Filed: 1986-08-13
Abstract: PURPOSE:To prevent erasion of data within a temporary memory element by providing a detecting part for abnormality of a power supply to detect it if occurs and actuating a back-up power supply. CONSTITUTION:In a normal mode the power supply voltage is supplied to a temporary memory element 2 and a central control part 3 from a main power supply 1. A power supply abnormality detecting part 4 delivers no detecting signal with its level higher than a prescribed one. Here the prescribed voltage range is set at 5V+ or -0.5V in the case of a transistor logic, etc. Therefore the part 4 detects the voltage drop of the power supply 1 down to 4.6V if caused by an abnormal state and outputs a detecting signal as long as it is prescribed to detect the voltage level of 4.6V set right before the level of the minimum working voltage. Thus a back-up power supply control part 5 performs switching control so that the power supply voltage is supplied to the element 2 and the part 3 from a back-up power supply 6. As a result, the contents of the element 2 is secured with high safety.
