Abstract: PROBLEM TO BE SOLVED: To improve speed of response by suppressing the effects of a parasitic photodiode. SOLUTION: A N<-> -type epitaxial layer 2, a P-type diffusion layer 3 and a N<+> -type buried diffusion layer 4 are formed on a P-type substrate 1. In addition, a N<+> -type diffusion layer 5, is of such a depth as to reach the N<+> -type buried diffusion layer 4, and a first P-type junction isolation diffusion layer 6, so deep as to reach the P-type substrate 1. In such a photodiode, a P-type buried diffusion layer 11 is formed on the epitaxial layer 2, in order to isolate the N<+> -type buried diffusion layer 4 from the epitaxial layer 2. A second P-type junction isolation layer 12, that is of such depth as to reach the P-type buried diffusion layer 11 and isolates the portion of the epitaxial layer 2 which is directly under the P-type diffusion layer 3 from the other portions, is formed around the P-type diffusion layer 3.  The P-type diffusion layer 3, the first and second P-type junction isolation layers 6, 12 and the N<+> -type diffusion layer 5 are brought to be at the same potential.

Upon starting the winding work, the current of a powder clutch 4b is set so as to be comparatively small to weaken the tension of the wire 2 whereby the damage of the wire 2 due to a riser can be prevented. Subsequently, during winding around the core teeth 9, the winding work is effected while generating a given proper tension and preventing the loosening of the wire. Upon finishing the winding work, a flyer arm 7 is decelerated and, therefore, the wire 3 is pulled out excessively and is loosened readily, however, the control current of the powder clutch 4b is increased upon finishing the winding work to increase the tension of the wire 3 comparatively whereby the pulled-out phenomenon of the wire 3 can be prevented.

Abstract: PROBLEM TO BE SOLVED: To allow the processor to process a compressed video signal subjected to in-frame image compression attended with shuffling, without accompanied by a time delay due to the de-shuffle processing and shuffle processing, and to provide an output of a compressed video signal. SOLUTION: A received compression video signal is expanded by a decoder 102, converted into a shuffled component signal and it is given to a YC separator 103, where the signal is separated into a luminance signal and a chrominance signal. The chrominance signal is separated into a U signal and a V signal by a UV separator 104, the color is corrected by multipliers 105, 106, 108, 109 and address 107, 110 and synthesized by a UV synthesizer 11, from which a chrominance signal after color correction is obtained. The chrominance signal after color correction and the luminance signal separated by the YC separator 103 are synthesized by a YC synthesizer 112 and compressed by an encoder 113 and outputted. Since color correction processing is conducted in a state of the video signal to be shuffled, no time delay is caused by de-shuffle processing and shuffle processing.
