Title: System for controlling number of revolutions of digital signal recording disc
Inventor: TAKAHASHI NOBUAKI
IPC: H02P29/00
Filed: 1982-05-31
Abstract: PURPOSE:To prevent the generation of an abnormal sound and the end break of a reproducing sound, by controlling the number of revolutions of a disc so as to make the residual amount of memory of a buffer memory constant. CONSTITUTION:A reproducing digital signal from a video disc player 15 is applied to a memory circuit 7 via a demodulating circuit 6. On the other hand, the memory residual amount of the buffer memory in the memory circuit 7 is detected at a master oscillator 10 and an up-down counter 11. The oscillating frequency of the master oscillator 10 is frequency-divided at a variable frequency divider 12 so as to attain constant memory residual amount and applied to a frequency divider 13 of the player 15. Thus, the rotation of a motor 3 and the disc 1 is controlled. Since the number of revolutions is controlled so as to make the residual amount of the buffer memory in the memory circuit 7 constant, no overflow or no deficiency of data exists in the memory circuit 7. Thus, such as the generation of an abnormal sound and the end break of a reproducing sound are prevented.

Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To execute high speed rolling of a steel sheet required for high gloss even when a new liquid is supplied to adjust concentration and a liquid level by using a uniform solution prepared through previous addition of a prescribed amount of water to a stock solution of a rolling mill lubricant as the rolling mill lubricant of an oil-in-water type emulsion. SOLUTION: Water of 1-10 vol.% is previously added to the stock solution of a rolling mill lubricant used as an oil-in-water type emulsion to get a uniform solution, then the solution is used as the emulsion of concentration-in-water of 1-10 vol.% and thus cold rolling of a steel sheet is executed at a high speed of >= 400 mpm. Above all, by making the amount of the upper limit of water added to the stock solution of a rolling mill lubricant equal or less than the amount of blending of the emulsion in the stock solution of the rolling mill lubricant, the required time for the particle size of the emulsion to become a stationary state is shortened.  Further, when the making-up supply is made after solubilization by previous addition of water to the stock solution of the roling mill lubricant, the average particle size of the oil in the water of emulsion is made into a fine particle size of <=3 μm.

Title: Interface circuit
Inventor: TAKADA YOSHIFUMI
IPC: G06F3/00
Filed: 1994-05-02
Abstract: PURPOSE:To reduce the power consumption of an interface circuit by setting the power voltage of a push-pull circuit at a potential lower than the circuit power voltage level. CONSTITUTION:An output circuit 4a is provided with inverters 11 and 12, NOR gates 13 and 14, and N-channel MOS 15 and 16 so that a push-pull circuit (output part) is obtained. The drain of the NMOS 16 is connected to a power voltage VTT (equal to the potential of the voltage VTT of a termination circuit), and the source of the NMOS 15 is connected to VSS. Then the power voltage VTT is set at a level, e.g. 1.2V which is lower than the internal circuit power voltage (VCC=3V or 3.3V) of a logic circuit element. As a relust, the power consumption is reduced. Furthermore the energy of reflected noises generated at each unmatched point when a low level is changed to a high level (a problem of GTL) is absorbed by an output transistor 16 kept in an ON state. Thus the converting performance is improved for the waveform ringing.
