Filed: 1991-03-22
Abstract: PURPOSE:To eliminate the need of circuit adjustment, to reduce the man-hour of processing and to uniform an adjustment accuracy by p providing an error correcting means automatically correcting the error generated when a signal is made discrete. CONSTITUTION:A Y/C separation part 202 separates an inputted composite image signal into a luminance (Y) signal and a color (C) signal. A decoder 203 generates an RGB (red, green and blue) signal from the luminance signal and the color signal.

The error can be corrected by setting the proportional factor in error correction part 2181 to 2183 and multiplying input data by it. Thus, an adjustment volume provided for eliminating the error occurred in the decoder 203 and the A/D conversion parts 2051 to 2053 can be eliminated.

Abstract: PURPOSE:To reduce a solenoid brake to a compact size by pressing an armature and a brake shoe to a drum by force of a spring for braking, and separating same from the drum by solenoid attraction force. CONSTITUTION:When an electric current is not supplied to a coil 4 of an electromagnet 2, each armature 7 is pushed open outwardly by elastic force of each spring 12, so that a brake shoe 10 is pressed to the inner peripheral surface of a drum 1. When an electric current is supplied to the electromagnet, each armature is attracted to the magnetic pole surface of a yoke 1 against the elastic force of the spring 12, so that the brake shoe 10 is separated from the inner peripheral surface of the drum 1. Thus, though this is a shoe-type brake, the brake can be reduced to a compact size like a disc type brake.
