Patent EP-0431366-A2 (EP)
Inventor: APITZ SIEGFRIED DIPL-ING
IPC: G11B15/18
Filed: 1990-11-16
Abstract: A video recorder with automatic still picture positioning senses during moving picture mode the levels of the waveform of the FM signal for successive fields and calculates a ratio from these levels. In still picture mode, the waveform levels are measured at respectively corresponding angular positions with respect to head switching pulses, and level ratios are likewise calculated. These actual level ratios are compared with set level ratios, as have been obtained from the moving picture level ratios in consideration of geometrical characteristics of the playback arrangement. From the deviations between level set values and level actual values, a respective tape position correction value is obtained. By constantly matching the level set values to the current ratios, it is ensured that the tape position correction values are appropriate for the current ratios. <IMAGE>

Abstract: During operation, the concentrator plane (3) and the stone extraction plane (4) are made to vibrate. Air is extracted at (19). The air which flows through the concentrator plane (3) fluidises the granular material which is let in through the feed (13) so that it flows off uniformly in an inclined direction. Components with a large specific weight collect on the underside, components with a low specific weight collect on the upper side of the stream. The components with a large specific weight drop down in the drop-through area (7). Components with a low specific weight move towards the light fraction outlet (14). As they drop downwards, the components with a large specific weight are braked by the airstream in the compartments (10), but cannot flow off in the inclined direction because of the transverse webs (11). They are therefore swirled in the compartments before they drop through openings of the second flow mask (9). By means of this swirling, a uniform turbulent airstream through the first flow mask (8) is ensured. As a result, disturbance to the coating of the granular material stream is avoided. In addition, since the uniform charging of the stone separating plane (4) is achieved, the stone separating process is improved. <IMAGE>

Abstract: A drum servo system provided with a rotation control device for controlling a rotation of a drum on the basis of a phase comparison signal obtained as a result of comparing the phase of an angle-of-rotation information signal obtained according to an angle of rotation of the drum with the phase of a control signal and a comparison control device for outputting the control signal to the rotation control device by performing a phase comparison or a frequency comparison by use of a frequency de-multiplication signal obtained by effecting a frequency de-multiplication of a reference signal having a frequency higher than a frequency of the control signal. Thus a radical change in the control signal, which occurs when the phase or frequency of the control signal is changed similarly as an abrupt disturbance from the outside, can preferably be absorbed in the comparison control device. Thereby, the rotation control means can always and stably follow the abrupt change occurring in the control signal.

Abstract: In a demodulating system for demodulating a modulated signal into decoded signals (S11'-12', S21'-22'), an error signal correcting circuit (55) is used in correcting discrimination error signals (Ep, Eq) supplied from a demodulator (52) in compliance with error location signals (Sp1-2, Sq1-2) supplied from an error-correcting decoder (54) and in producing corrected discrimination error signals (Ep', Eq') for supply to an adaptive equalizer (51) which is additionally supplied with polarity signals (Dp, Dq) from a delay circuit (53). The modulated signal is equalized in accordance with the corrected discrimination error signals and the polarity signals, demodulated into demodulated signals and the discrimination error signals, and error corrected and decoded into the decoded signals. The delay circuit delays P-channel and Q-channel polarity bits of the demodulated signal into the polarity signals. The error-correcting decoder produces the error location signals by using P-channel and Q-channel error correcting code bits of the demodulated signals. The modulated signal may be supplied first to the demodulator and then to the equalizer.
