SOLUTION: A PWM circuit part 7 generates an outputs a PWM signal 7a with a duty factor corresponding to A/D converted data of a sample-and-hold voltage VA. The PWM signal 7a is smoothed by a low-pass filter circuit 5 to obtain an analog voltage VD. Differential amplifiers 3 and 4 output the voltage generated by raising to n-th power the difference voltage between the sample-and-hold voltage and analog voltage. A control part 8 puts together the A/D converted data as the amplification output of the difference voltage and the A/D converted data of the sample-and-hold voltage to obtain A/D converted data of resolution which is n-bit higher than the resolution of the A/D converter.

A valve 3 is soft and a bundle can be removed easily.  A hook 4 at the end part of the bundle inserted supports cables and connecting terminals with a necessary stopping force and when these are pulled strongly, these can be pulled for repeated use. As a result, the box is compressed for the convenience of storage, transportation and carrying and the bundling work can be made easier at the time of use.

Abstract: PURPOSE:To make a displayed image easily seeable as well as to make it so as to have the extent of sufficiently high resolution, by properly adjusting a state of microscopic irregularities of silicon dioxide to be formed on a panel outer surface of a cathode-ray tube. CONSTITUTION:Alkoxide Si (OR)4 is sprayed to an outer surface of a bulb panel of a cathode-ray tube and burned for formation, whereby a bolt lot of transparent and fine tray-like irregularities of silicon dioxide, formed in a circle of 5-20mum in a mean diameter and being protuberant in the periphery part, are formed there. That is to say, a Si (OR)4 solution with nitric acid of less than 1% as a catalyzer is sprayed to the panel outer surface of the CRT with a spray gun and, after burning, a film, with microscopic irregularities, of SiO2 strongly stuck to the panel surface is formed there. With this constitution, a larger side in a mean diameter of the traylike body comes to lower in resolution in general, and if this mean diameter becomes more than 20mum, for example, 40mum so much, the desirable resolution is not secured even if the non-glare degree is good.
