Title: Picture quality adjusting circuit
Inventor: KOTSUBO KAORU
IPC: H04N5/93
Filed: 1982-12-01
Abstract: PURPOSE:To curtail the number of parts and to obtain an inexpensive picture quality adjusting circuit by using in common a resonance means of an equalizing circuit as a resonance means of the picture quality adjusting circuit. CONSTITUTION:A video signal from a head amplifier 1 is supplied to an equalizing circuit 11 provided with resonance elements 11a, 11b through a trap circuit 10. Also, a variable resistor 80 is connected between an output terminal of the resonance element 11b and a ground. This resistor 80 forms a picture quality adjusting circuit by co-operating with the resonance element 11b. That is to say, by varying a resistance value of the resistor 80, the gain of resonance frequency of the resonance element 11b can be varied, and the picture quality is adjusted. In this way, since the resonance means of the equalizing circuit is used in common as the resonance element of the picture quality adjusting circuit, the number of parts is curtailed, and an inexpensive picture quality adjusting circuit can be obtained.

Abstract: PURPOSE:To make it possible to measure the accurate pressure without temperature errors by obtaining intrinsic resonance resistance (Z0 + Zt) at a temperature T. CONSTITUTION:A constant-voltage AC power supply is formed of a full-wave rectifier 3, a 1/10 attenuator 4, a comparator 5 and a voltage-controlled attenuator 6. The power supply is connected to a piezoelectric transducer 1. Thus a self-oscillating circuit is formed. The resonance current undergoes current to voltage conversion 2 and full-wave rectification 7. The signal corresponding to a resonance resistance Z is applied on one terminal of operating circuit 8. A resonance frequency (f) is applied on the other terminal of the circuit 8. In the operating circuit 8, the temperature T and the intrinsic resonance resistance (Z0 + Zt) for the resonance frequency (f) are obtained. Then,  Z = Z - (Z0 + Zt) is operated. The pressure P of a gas corresponding to  Z is obtained. Then, the errors due to the temperature at the piezoelectric transducer 1 can be eliminated.

Abstract: PURPOSE:To enable a starting current to be controlled according to the operation of a fan by providing a fan-controlling means for limiting a voltage applied to the fan, until a predetermined rotating frequency is detected by a fan rotation detector when the operation of the fan is started. CONSTITUTION:With a combustion fan 1 started at time t0, an applied voltage setting signal VSL set on a combustion fan controller 8 and a triangular wave oscillating output from an oscillator 2a are compared with each other by a comparator 2b. A control signal PWML for an ON time period is outputted from an output terminal of a transistor 2c, a voltage VHL to be applied to a combustion fan 1 is obtained at an output of a chopper circuit, and the fan 1 is started with the voltage VHL as a starting voltage. A rotation detector 3 for the fan 1 generates a rotation detection signal NS at time tn when a value detected by the detector 3 reaches FS. The controller 8 sets an applied voltage setting signal VSH at a setting terminal 8a, and the comparator 2b outputs a control signal PWMH for a longer ON time, whereby the applied voltage obtained at the output of the chopper circuit is raised from VML to VMH.

Title: Removal of iron using transferrin
Inventor: MORIYA TOSHIYASU
IPC: C12G3/02
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To make only iron selectively absorbed and removed from drink water, water for brewing and prevent coloring or quality deterioration, etc., of refined rice wine, etc., by using transferrin. SOLUTION: Iron in water or refined rice wine is removed by using transferrin. Ovotransferrin obtained by removing, e.g. ovalbumin from egg albumen by crystallization and then carrying out ion exchange chromatography of the treated egg albumen can be used as the transferrin. The transferrin can be used in an immobilized state. Furthermore, when refined rice wine is treated with a column of immobilized transferrin, ferriferrichrysin concentration in refined rice wine is preferably lowered using malted rice for producing deferriferrichrysin in a low concentration, because iron ion in refined rice forms a chelate together with deferriferrichrysin. Iron ion in the refined rice wine can also be removed as dregs by iron removing treatment due to addition of ovotransferrin and deproteinization treatment due to firing or lowering of dregs.

Title: Stepping motor control device
Inventor: KONO TAKANORI
IPC: H02P8/00
Filed: 1992-07-18
Abstract: PURPOSE:To reduce overshoot to thereby improve positioning accuracy by generating a pulse at a timing substantially equal to a peak timing of an overshoot generated in a stepping motor by a pulse immediately before a stop-phase pulse of the stepping motor. CONSTITUTION:A drive pulse is updated at a timing (virtual stop point) preceding by a response delay TS from a peak point P of an overshoot of a step one step before a stop point SP so that rotation of a stepping motor starts at the peak point P of the overshoot of the step one step before the stop point SP. Since the stepping motor step-rotates from the peak point P of the overshoot of the step one step before the stop point SP toward the stop point SP, a movement theta of the final step is minimized to thereby minimize an overshoot occurring after passage of the stop point SP.
