Title: Method and apparatus for measuring hall voltage
Inventor: YAMAGUCHI HIROMI
IPC: G01R33/12
Filed: 1994-10-17
Abstract: PURPOSE: To improve the reliability of a measured value even under such a condition that the Hall voltage becomes smaller than a non-balanced voltage by altering the combination of directions, etc., of a current for every stage of increasing the magnetic flux density of an applied magnetic field. CONSTITUTION: An electromagnet 4 gives a magnetic field perpendicularly to the surface of a semiconductor sample 10 according to a current from a power source 3, and a constant-current source 5 supplies a current to the four electrodes of the sample 10 via a scanner 6. The magnetic flux density of the applied field is stepwise increased, the combination of the direction of the current, the direction of the field and the voltage measuring electrode is altered for every increasing stage, and the voltage is measured by a voltmeter 7. By conducting the summing mean of the measured voltages, a first mean value is obtained. And also, by conducting the summing mean of the values obtained by subtracting the first mean value from the measured value, a second mean value is obtained.  When the magnetic flux density is proportional to the second value, the second value is decided as the Hall voltage, and when it is not proportional, the first value is decided as the Hall voltage.

Abstract: PURPOSE:To perform change of direction of a magnetic field only by switching operation by providing switches each one is connected to both sides of a coil and an external magnetic field generating device provided with a power source and a variable resistor connected in series to the coil. CONSTITUTION:At the time of recording, a terminal 5a side is closed by a switch 4a, and a terminal 5c side is closed by a switch 4b. Then, the value of resistance of a variable resistor 3 is set by changing the value of current that flows in a coil 1. Then, a magnetic field of reverse direction to the arrow mark A is generated. When erasing, a terminal 5b side is closed by the switch 4a and a terminal 5d side is closed by the switch 4b. The value of the variable resistor 3 is set next. Then a magnetic field of reverse direction to that at the time of recording is generated. At the time of reproducing, one or both of switches 4a, 4b is opened. Thus, the direction of magnetic field at the time of erasing and recording can be set only by changing of switches, and when reproducing, generation of a magnetic field can be stopped only by opening the switches.

When the difference between the lift amount 17 at the present point of time and the lift target value is the set value or more by the discrimination, the control is carried out by shortening the feedback time of the lift amount 17 and when the difference is less than the set value, the control is carried out by extending the feedback time of the lift amount 17. Thereby, the exhaust gas recirculation amount can be controlled properly and the generation of a black smoke can be restrained.

Abstract: PURPOSE:To prevent a battery from becoming completely flat in synchronized flash photography by a stroboscope by turning off a stroboscope power source unless a light emission ready signal and a charge end signal are outputted within different specific reference times. CONSTITUTION:When the voltage of a battery E is supplied to a CPU1 by turning on a switch S1, the switching transistor (TR) of a stroboscope unit 2 is turned on by the CPU1 and the unit 2 starts operating. Then, the CPU1 turns off the TR of the unit 2 unless the light emission ready signal is inputted from the unit 2 within the 1st reference time after the charge start of the main capacitor of the unit 2 and the charge end signal is inputted from the unit 2 within the 2nd reference time whose end is later than the 1st reference time, thereby cutting off the electric power supply to the unit 2 when the voltage of the battery E drops. Thus, the battery becomes completely flat in stroboscope photography and a film winding and a rewinding device, etc., are put in operation.

Filed: 1985-11-12
Abstract: PURPOSE:To quickly and thoroughly remove water from a disk member and to quickly dry said member by supplying hot water to the surface of the disk member during the low-speed rotation thereof and rotating the disk member at a high speed after the warming. CONSTITUTION:A spindle 12 of a motor 13 for a rotating device 2 is rotated, by which the disk member 1 is rotationally driven at a low speed of about 100-500rpm. The hot pure water heated to >=40 deg.C is supplied from nozzles 33 of a hot pure water supply device 3 to the front and rear surfaces of the disk member 1 at the same instant. The supply of the hot pure water from the hot pure water supply device 3 is stopped when the front and rear surfaces of the disk member 1 are thoroughly heated. The disk member 1 is then rotated at a high speed of 2,000-5,000rpm and the water sticking to the surface of the disk member 1 is removed by the effect of centrifugal force. Since the disk member 1 is kept heated by the hot pure water in the above-mentioned manner, the draining on the surface thereof is improved and the water in molecular order is thoroughly removed. The drying of the disk member 1 is thus accelerated.
