Title: Optical disk device
Inventor: TAKASUGI KAZUO
IPC: G11B7/09
Filed: 1987-10-02
Abstract: PURPOSE:To obtain a simple device with high reliability by processing a signal based on the area of a detection signal waveform so as to take a large permissible fluctuation with respect to a timing window pulse signal for the detection. CONSTITUTION:In obtaining a TR signal from a pre-wobble pit, a reproducing signal from each pit is detected differentially with respect to one set of pits subject to pre-wobbling processing. The differential method is implemented by using the area of each waveform. A reproduced waveform is sliced at a prescribed level in obtaining the area to eliminate the effect of disk surface noise or the like thereby obtaining a reproduced waveform area of each pit of L, R. The TR signal is obtained based on the reproduced waveform area difference between the L and R pits, while the presence of error in the TR signal is decided by the difference of the area of the reproduced waveform between adjacent pits biased unidirectionally. Thus, the simple device with high reliability is obtained.

Title: Synchronizing circuit for dot sequential color multiple signal
Inventor: MIYOSHI TADAYOSHI
IPC: H04N9/07
Filed: 1988-09-30
Abstract: PURPOSE:To prevent the generation of a color pseudo signal by suitably adding a synchronized chrominance signal before and after thinning timing, and making it into a demodulated chrominance signal for the specific chrominace signal corresponding to the thinning timing. CONSTITUTION:Respective R(red), G(green), and B(blue) chrominance signals from FIR filters (definite response filter) 7 to 9 are latched (thinned) by a prescribed synchronizing clock, for example a clock fs, and outputted as the demodulated chrominance signal. At such a time, for the specific chrominace signal corresponding to the thinning timing, the chrominace signal synchronized before and after the thinning timing is suitably added to be the demodulated chrominace signal. Thus, the characteristic of an MTF (modulating degree) becomes the same among the respective R, G and B chrominace signals, and the generation of the color pseudo signal is prevented.
