Title: Fixed-length delay generating circuit
Inventor: IIDA TOMOHIRO
IPC: G11C11/4076
Filed: 2000-11-21
Abstract: PROBLEM TO BE SOLVED: To provide a fixed-length delay generating circuit, capable of suppressing fluctuations in delay values caused by production conditions and environmental changes. SOLUTION: On the basis of the phase comparison of a delay clock signal D4, outputted from a variable delay circuit group 3 and a frequency divided clock signal (1/n)CLK, feedback control is applied to delay in the variable delay circuit group. At this time, since the variable delay circuit group 3 is composed of second variable delay circuits 2-1 to 2-4 for generating delays equal to a first variable delay circuit 1, the first variable delay circuit 1 adds a delay matched with a delay by means of the second variable delay circuits 2-1 to 2-4 to an input signal and outputs it simultaneously with the feedback control. Therefore, since delay control in the first variable delay circuit is performed on the basis of phase comparison, error hardly occurs in the delay values, while being hardly affected by the input signal, element parameters and environmental changes.

Title: Method and device for washing tube surface of cathode- ray tube
Inventor: SUGIYAMA KOHEI
IPC: H01J9/38
Filed: 2000-12-06
Abstract: PROBLEM TO BE SOLVED: To effectively wash off the organic contaminant remaining on the tube surface even after a polishing process. SOLUTION: When the tube surface of a cathode-ray tube 1 on the side with its panel part is to be washed, a finishing process is conducted upon a polishing process of the tube surface, and thereafter the tube surface is washed by decomposing and removing the attached organic contaminant with a plasma stream. If plasma stream is blown to the tube surface after the polishing and finishing processes, the attached contaminant of organic series substance is decomposed and removed. As a result, the fluid contacting angle of the tube surface is decreased, and the washing effect is improved to a great extent. This heightens the bonding strength of the surface processing film attached by coating to the tube surface, and the film will not exfoliate simply from the tube surface. This lessens the likelihood of generation of poorly finished products originating from film exfoliation.
