Filed: 1985-02-28
Abstract: PURPOSE:To attain a time arrangement between three kinds of reproduction signals by so forming the titled device that the delay times of variable delay circuits provided in the transmission lines of the three kinds of reproduction signals obtained from the reproduction signals reproduced from N-pieces tracks, are variably controlled based on the signals obtained by respectively comparing the phases of the synchronous signals while referencing the synchronous signal in the reproduction signal from a specified track. CONSTITUTION:A reproduction luminous signal is delayed by a period of H/2, and the resulting delayed reproduction luminous signal is outputted to an output terminal 36 through a low pass filter for clock-pulse-frequency component removal 35, and also outputted to a horizontal-synchronizing-signal separating circuit 37. The second reproduction FM color difference components taken out from a band filter 40 is supplied respectively to a trap circuit 45 and a synchronous signal separating circuit 46. A phase comparator 51 respectively compares the reproduction horizontal synchronizing signal from a horizontal synchronizing-signal separating circuit 37 with that from the synchronous signal separating circuit 46 to generate a phase-differential voltage according to the phase difference, and supplies it to a voltage control oscillator (VCO) 52 as its control voltage in order to variably control the VCO's repetition frequency (oscillating frequency).

Title: Waveform generator
Inventor: KANEAKI TETSUHIKO
IPC: G10H7/00
Filed: 1986-02-25
Abstract: PURPOSE:To obtain a waveform having high resolution of frequency without increasing the number of memories nor the size of a multiplier, by turning the interpolation value of an interpolator into an output waveform. CONSTITUTION:An accumulator 2 accumulates successively the constants C produced from a constant generator 1 and a reader 3 reads the waveform data out of a memory 4 based on the higher bit INT of the output of the accumulator 2 and sends it to an interporator 5. The interpolator 5 performs the interpolating arithmetic of the waveform data received from the reader 3 based on the lower bit FRAC of the output of the accumulator 2. Here the interpolator 5 does not use all lower bits of the output of the accumulator 2 to perform the interpolating arithmetic but uses only the higher ones of those lower bits. Thus the interpolator 5 can use a small number of digits for arithmetic. this can reduce the scale of the interpolator 5.

Abstract: PURPOSE: To float scum by the bubbles formed when high-pressure water is released, and enable high-concn. waste water to be treated with a small-sized apparatus by injecting treating water together with air under pressurizing from the upper stream side of plural pressure vessels which are piped in series, detecting the high water levels on the lower stream side vessels and releasing the water.  
     CONSTITUTION: The waste water supplied in a reservoir 1 is removed of scum in a prestage scum removing tank 3, and this waste water is supplied of nutrient salts for microbes from a supply pipe 12 in a reservoir 11. Next, it is pressurized by a pump 14 and is injected together with the high-pressure air of a compressor 8 to the upper part of a vessel 13. The treating water is flowed down in a cylinder 13a by the impellers 13b of the vessels 13, 15, 16, and circulates by ascending on the circumference, then the pressures in the vessels rise. Thence, the air is dissolved into the treating water according to pressures to enhance DO. The treating water is oxidation-treated by microbes. The air having failed to dissolve in the treating water is released from a pipe 17. When the water level gage 20 of the vessel 19 reaches an upper level, a valve 21 opens to release the water into a water tank 22, thereby lowering the water pressure. The dissolved gas floats scum as bubbles and the scum is removed. The treated water is discharged from a pipe 23.
