Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of a magnetic noise and to obtain a clear image by a method wherein a chassis bottom plate in the lower part of a board on which a switching transformer is installed is drilled and the generation of a power-supply noise due to a leakage flux from the switching transformer is prevented.

An opening part 4 is drilled in the chassis bottom plate 1 near the switching transformer 3. Even when the switching transformer 3 is not magnetically shielded or the like, the generation of an eddy current due to a leakage flux is small, and it is possible to effectively prevent the disorder of an image due to a magnetic noise. In addition, the number of components for this magnetic recording and reproducing apparatus can be reduced, the costs of the apparatus can be reduced, the assembling operation of the apparatus is simplified, and the weight of the apparatus can be made light because a part of a thick iron plate is drilled.

Title: Electrostatic deflecting image pickup tube
Inventor: AIZAWA SHIROU
IPC: H01J29/74
Filed: 1984-02-15
Abstract: PURPOSE:To improve the reliability of both the electric contact and the life of an electrostatic deflecting image pickup tube by forming a conductive contact by superimposing an outer high thermal expansion coefficient metal touching a deflecting electrode and an inner low thermal expansion coefficient metal upon each other. CONSTITUTION:A conductive contact 10 is formed by affixing together an outer high thermal expansion coefficient metal 11 touching a deflecting electrode 9 and an inner low thermal expansion coefficient metal 12. When the atmospheric temperature nears the softening point of the glass of a tube body 8 during heating of the deflecting electrode 9, the outer high thermal expansion coefficient metal 11 much more extends than the inner metal 12 and therefore the conductive contact 10 separates from the deflecting electrode 9. Therefore no internal pressure is applied to the tube body 8 from its inner side at a temperature of at least the above softening point. As a result, the electrode 9 can be sufficiently baked, thereby improving the reliability of the life of an electrostatic deflecting image pickup tube. Furthermore, the tube body 8 is not deformed due to the absence of internal pressure and the conductive contact 10 sufficiently touches the electrode 9 again after the atmospheric temperature returns to normal, thereby improving the reliability of electric contact.
