Title: Muting circuit
Inventor: TANAKA YOSHIAKI
IPC: H03F1/00
Filed: 1989-01-12
Abstract: PURPOSE:To reduce or eliminate the shock sound for switching to muting by nearly equalizing the DC voltage of a noninverted input terminal for the normal state and that for muting. CONSTITUTION:At the time of the steady state, the current of a constant current source Ia is supplied to the base terminal of a transistor TR Q3 through a current mirror circuit consisting of TRs Q18 and Q19 and it is turned on. When a mute control signal is inputted to a mute control terminal 6, a current is supplied to base terminals of TRs Q1 and Q2 and they are turned on, and signals inputted to input terminals 1 and 2 are attenuated, and no signals are outputted from an output terminal 3, and thus, muting is applied. At this time, a TR Q23 is turned on and the current is supplied to the constant current source Ia through a current mirror circuit consisting of TRs Q20 and Q21, and thereby, current supply to the base terminal of the TR Q3 is stopped and the TR Q3 is turned off. Thus, the DC variation of the output terminal 3 does not occur, and shock for switching to muting is eliminated.

Title: Method and apparatus for detecting displacement of high polymer material
Inventor: HIRAKAWA KOUICHI
IPC: G01B7/24
Filed: 1983-01-17
Abstract: PURPOSE:To detect simply and highly precisely a displacement due to variations of volume and temp. caused by hardening reaction by adhering a magnetic material whose magnetic characteristic is varied by stress to a thermoplastic polymer material or a thermosetting polymer material capable of polymerizing by the reaction, and detecting an extent of displacement of the high polymer material with the variation of the magnetic characteristic of the magnetic material. CONSTITUTION:The material of a sample case 4 filling the high polymer material or monomer consists of a nonmagnetic material which is not deformed and deteriorated within a temp. range of measurement. In case the material of sample case has a large adhesive strength against the sample 5 or the influence of the adhesion is desired to be small, a mold release layer efficient to the sample is formed to the inner surface. An amorphous alloy capable of adjusting easily the magnetostriction constant by varying the composition corresponding to the extent of displacement of the polymer material to be measured and capable of varying magnetic characteristic such as magnetic permeability remarkably due to the strain is suitable to a sensor material 6, but the material is not restricted by said alloy. Since Young's modulus of polymer, e.g. epoxy resin is about 250kg/mm.<2> and that of the material 6, e.g. amorphous alloy is about 12,000kg/mm.<2>, the extent of variation of the material 6 corresponding to the displacement of the polymer material is extremely small.

     CONSTITUTION: In the inner peripheral wall of washing tank 2, there are formed grooves 6, 7 at the levels substantially equal to those of upper and lower overflow ports 10, 8. These grooves 6, 7 are communicated respectively to the overflow 10, 8. During rinsing operation of washer, water surface in the washing tank 2 is depressed  at its central portion by the function of centrifugal force caused by pulsator, so that the water surface in tank 2 becomes substanially conical. Under such circumstances, a portion of water in the tank 2 is discharged directly from overflow ports 10, 8, but most of the water flows over bulkheads 11, 12 of grooves 6, 7 and drops into the grooves 6, 7 with water head A. Bubbles and suspended matters like yarns floating on the water surface are drawn into the grooves together with water and discharged to the outside from a suitable outlet.

Filed: 1990-01-18
Abstract: PURPOSE:To effectively perform an interval reproducing mode for automatically reproducing tracks in turn on a recording medium at intervals of a prescribed time by automatically releasing an automatic shut-off mechanism from its function when the interval reproducing mode is selected. CONSTITUTION:When a reproducing mode selecting switch 54 is at an L-level and under the interval reproducing mode, whether an interval timer 47 is overflow or not is then detected, and if it is not overflow, the detecting operation is shifted to a power switch 51 after reset start operations of a medium protection timer 46 and the interval timer 47. In the case of an overflow, a magnetic head 21 is moved to the next track, and at the me time, the reset start operations of the medium protection timer 46 and the interval timer 47 are performed to reproduce this track. That is, the automatic shut-off mechanism for shutting a power source automatically when the continuous reproducing time on the same track is passed in a fixed time should not be worked. By this method, the interval reproducing mode can effectively be performed.
