Title: Coating method for color cathode ray tube and its device
Inventor: KIYONO AKIRA
IPC: H01J9/227
Filed: 1993-02-08
Abstract: PURPOSE:To prevent a phosphor film coated on the inner screen of a panel from being non-conformable by recovering phosphor while both the panel and a recovery cover are being simultaneously changed in angle with an identical angle kept on. CONSTITUTION:When a motor 11 for changing the angle of a panel is normally rotated, a ball screw 12 is rotated, and a driven gear 4 is then rotated in the direction indicated by an arrow head D via a ball nut 13, a lever 16, a piston rod 18, a crank rod 20 and a drive gear 22. And when the motor 11 is reversely rotated, the gear 4 is rotated in the direction indicated by an arrow head D'. And when a motor 34 for changing the angle of a recovery cover is normally rotated, a driven gear 32 is made to be rotated via a drive gear 35 in the direction indicated by an arrow head F identical to the arrow head D indicating the rotational direction of the gear 4. And when the motor 34 is reversely rotated, the gear 32 is made to be rotated in the direction indicated by an arrow head F'. This constitution thereby allows both the panel 1 and the recovery cover 33 to be changed in angle while an identical angle is being kept on, and also each angle of the panel and the cover is being changed little by little. Therefore, when phosphor is recovered, the device can prevent phosphor within a carrier 2 from being excessive in movement, and can thereby prevent a phosphor film from being non-conformable.

Abstract: PROBLEM TO BE SOLVED: To form an Si fine line having a pattern width smaller than the original mask in accordance with the amount of shift by arranging at least two lines of mask patterns in such a manner that the mask patterns are shifted in a vertical direction relative to a surface having a lower etching speed. SOLUTION: Mask patterns 1 and 2 having the same width W are formed in the direction of <-112> axis on Si (110) of a substrate. At that time, the mask patterns 1, 2 are relatively shifted by Δorthogonally to <-112> axis and the Si (110) of the substrate is anisotropic-etched with KOH. At this time, the etching speed of Si (111) plane is very slow, and the Si (110) substrate, which is etched by the mask patterns 1, 2 in <-112> direction, obtains a vertical side face since the side face of edge has an Si (111) plane. On the other hand, the edge of a portion for which the mask pattern is shifted by Δ obtains an Si plane with a high etching speed in a direction orthogonal to <-112> axis, undercut advances by L at right and left edges respectively in opposite direction, and Si thin line having the width of W-Δ can be obtained easily over a length of 2L.
