Title: Spiral conveyer
Inventor: SUZUKI MASAFUMI
IPC: B65G47/52
Filed: 1991-06-19
Abstract: PURPOSE:To provide long durability of the whole conveyer and carry a large weight of transferred article smoothly upward by preventing the inward transferring force of a transferring belt from becoming excessively large even when the large weight of transferred article is transferred upward. CONSTITUTION:With this spiral conveyer pulled up by an upper taper roller 2 and pushed up by a lower taper roller 2, the transferring surface of a transferring belt 3 is moved, so tensile force which works on the transferring belt 3 does not increase not as usual even if the total rotational driving force of the taper rollers 2, 2 are large. Therefore, the inward moving force of the transferring belt 3 does not increase not as usual. As a result, the transferring belt 3 hardly comes off between upper and lower rotational bodies 42, 43. Namely, a large weight of transferred article can be transferred upward easily. Besides, because the inward moving force of the transferring belt 3 does not increase as usual, the imposed load of the conveyer belt does not increase. It is thus possible to prolong the durability of the conveyer.

Title: Carrier-wave type strain amplifier
Inventor: IMANISHI YASUO
IPC: G01R5/16
Filed: 1979-11-14
Abstract: PURPOSE: To obtain the amplifier outputting a stable strain signal accurately without being influenced by the change in temperature, etc., by a simple consititution, by feeding back a prescribed electric signal to a bridge circuit containing a strain gate and thereby erasing the signal corresponding to the imbalance in capacity.  
     CONSTITUTION: When a carrier wave such as a sine wave is given from a bridge power source 8 to the bridge circuit 1 containing the strain gage 1a, a synchronous rectifying circuit 10 outputs a strain signal in accordance with the imbalance corresponding to the resistance, while a 90° phase synchronous rectifying circuit 11 generates a DC output due to a suspension, capacity and a imbalance capacity. This output and a signal whose phase is diverged at an angle of 90° to the carrier-wave voltage of the power source 8 via a phaser shifter 21 are multiplied in a four- phenomenon multiplying circuit 22. And, when the feedback control is conducted by adding the output of the circuit 22 to an adder 23 in the direction where the output of the phase shifter 21 approaches zero, the signal caused by the imbalance in capacity is erased to be zero. Thus, an amplifier which does not perform the control of the variable resistance of the bridge circuit through the intermediary of a motor and the like but gives a stable and correct strain signal in the simple constitution by means of an electric feedback control and without being influenced by vibrations, change in temperature, etc. is obtained.

Title: Pulse width modulation power amplifier
Inventor: WATANABE TOSHIHIKO
IPC: H03K7/08
Filed: 1977-12-09
Abstract: PURPOSE:To establish the pulse width modulation power amplifier to drive the load such as motor, in which the gain is constant independently of the variation of power supply voltage. CONSTITUTION:The relation of amplitude between the input signal voltage and the triangle wave voltage outputted from the oscillator OSC1 is compared with the comparator C. When the output of the comparator C is at a high potential, the forward biad between the base and emitter is fed only to the transistors TrQ2, Q3 and the current toward left flows to the motor MR via TrQ2, Q3, and the output of the comparator C is at low potential, then the current toward right flows to the motor MR via TrQ1 and Q4. In this case, the output amplitude of the oscillator OSC1 is taken so that it is in proportional to the power supply voltage.

Title: High frequency switch

IPC: H03K17/693
Filed: 1995-06-15
Abstract: PURPOSE: To realize the high frequency switch with high isolation and a low pass loss by connecting an inductor in parallel between a drain terminal and a source terminal of a field effect transistor (FET) so as to cancel the parasitic capacitance caused when the FET is nonconductive. CONSTITUTION: An inductor is connected in parallel between a drain terminal and a source terminal of a field effect transistor (FET) so as to cancel the parasitic capacitance caused when the FET is nonconductive. For example, an inductor L1(L2) is connected in parallel between a drain terminal and a source terminal of a FET2 (3) (each acting like a single pole double throw (SPDT) switch) through which a transmission (reception) signal passes to prevent increase in a passing loss and deterioration in the isolation due to parasitic capacitance. Although parasitic capacitance of FETs 1, 4 for grounding purpose causes increase in a passing loss at reception and transmission respectively, since the optimum gate width of the FETs 1, 4 is often narrower than the gate width of the FETs 2, 3, the parasitic capacitance caused when the FETs 1, 4 are nonconductive is negligibly small.

The power from a battery 21 is supplied to the transmitter 18 at a specified time interval with the timer of a power control circuit 20. A radiowave is intermittently transmitted. The radiowave is received with a receiver 22. The frequency is detected, and the water level can be found. The hot water feeding into the bathtub 1 is controlled in correspondence with a preset water level.
