IPC: H03M1/12
Filed: 1995-03-31
Abstract: PURPOSE: To reduce the cost and power consumption while sustaining high speed by providing two hold capacitors for holding the sampled input signal voltage alternately, and an operational amplifier circuit outputting a hold voltage. CONSTITUTION: When a control signal ϕ1 goes high, hold capacitors 1, 2 enter into a state for sampling the input signal voltage. On the other hand, an operational amplifier circuit 20 enters into a state for holding a differential voltage corresponding to the charges stored in the hold capacitors 1, 2. The hold output is derived from differential output signal terminals Vout<-> , Vout<+> . When the control signal ϕ1 goes low, the circuit 20 holds the input signal voltage, being sampled when the control signal ϕ1 is high, and outputs the voltage thus held. On the other hand, hold capacitors 3, 4 enter into a state for sampling the input signal voltage.

Filed: 1981-05-19
Abstract: PURPOSE:To obtain a useful demagnetizer of simple structure by driving a permanent magnet by variation in the external diameter of a tape hub wound with a tape and the rotation of the hub, and thus producing an attenuating oscillation magnetic field. CONSTITUTION:A tape 6 while wound around a payoff side reel hub 14 is run in play mode. A pulley 7 is pressed against the external circumference of a take-up side reel hub 15 by a spring 10 and then rotates together with a belt 8 made of rubber. A movable lever 9 supporting the pulley 7 moves up and down around a supporting shaft 11 and supports another pulley 12. In the pulley 12, a permanent magnet 13 magnetized alternately to the N and S polarities is embedded and according to the rotation of the pulley 7, an oscillation magnetic field is established. As the reel hub 15 being wound with tape increases in external diameter, the pulley 12 moves away from a magnetic head 5 to generate an attenuating oscillation magnetic field, thus easily demagnetizing the magnetic head 5. Any special power source is not required, so the structure is simplified.

Abstract: PURPOSE:To enable the precipitation of homogeneous diamond with a large area by installing a conductive net enclosing a combustion region so that the diamond can be synthesized at a high yield by the vapor phase method with the simple device and scale-up is facilitated. CONSTITUTION:The conductive net 8 enclosing the combustion region is set and a voltage is applied thereto at need at the time of synthesizing the diamond by burning a raw material compd. for precipitation of diamond contg. carbon in such a manner as to have the incomplete combustion region 3, installing a base material 5 for diamond precipitation in this incomplete combustion region 3 or a non-oxidizing atmosphere near said region and holding the temp. thereof at the diamond precipitation temp. The volume of the combustion flame shrinks when the impressed potential is positive with the net and the volume expands when said potential is negative with the net. The energy density increases in case of the shrinkage of the combustion flame and decreases in case of the expansion. The energy density increases as well even at 0 impressed voltage. The diamond is thus synthesized at the higher yield than heretofore and the scale-up is facilitated. The homogeneous diamond is thus precipitated with the large area.

Title: Motor control circuit for tape recorder
Inventor: MOCHIDA YOSHIO
IPC: G11B15/02
Filed: 1986-04-03
Abstract: PURPOSE:To prevent a tape running system from stopping on the way of the switching of a running state, by providing an off detecting and holding part and an FF part that detect the off state of a switching element which is interlocked with a rapid traverse/rewinding button, and holds it for a reulated time. CONSTITUTION:At the time of a rapid traverse/rewinding operation, when the second switching element 3 interlocked with the rapid traverse/rewinding button is turned off, the fact is detected by an off detecting and holding part 11, and the output of the holding part 11 becomes high for the regulated time. In such case, a time while the high level of the part 11 is kept, is set as a little longer than the time from when the output of a motor driving part 7 becomes low, and the power source of a motor 8 is turned off, until when the rotation of the motor 8 stops actually. And when a play button is depressed after the rapid traverse/rewinding is removed in a high level time, and before the rotating speed goes to zero, the motor 8 is driven again through an FF13, and the motor 8 stops after the first running system 9 goes to a playing state completely. In this way, the running state of the tape running system 9 is prevented from stopping on the way of the switching, and inconvenience, such as a state impossible to take out the tape, can be eliminated.
