摘要： A gate turn-off thyristor drive system with low power loss when it is in the turn-off mode, is disclosed. A first turn-off pulse of a predetermined amplitude is applied to a first gate electrode. A second turn-off pulse is applied to a second gate electrode. An amplitude of the second turn-off pulse is smaller in absolute value than that of the first turn-off pulse. The fall time of the anode current at the time of turn-off is reduced, and the initial value of the tail current of the anode current is reduced. The power loss as the product of the anode voltage and the anode current is reduced.

摘要： An invisible symbol reading apparatus includes a heating unit for heating an invisible symbol formed on a sample and containing a material which emits infrared light when heated, a detecting unit for detecting infrared light emitted from the invisible symbol, and an arithmetic operation unit for binarizing a detection signal from the detecting unit. The arithmetic operation unit calculates a differential coefficient of the detection signal, that corresponds to a position on the sample. On the basis of upper and lower threshold values set for the differential coefficient, the arithmetic operation unit determines a maximum value of the differential coefficient in a region exceeding the upper threshold value and a minimum value of the differential coefficient in a region smaller than the lower threshold value. The arithmetic operation unit binarizes the detection signal by using the maximum or minimum value as a leading or trailing edge of a binary function.

摘要： A centrifugal separating-distributing apparatus includes a body being provided with an intake path, a stacking path, and a distributing path. A fluid sample is taken into the intake path, and the sample flows out from an outlet of the path when a first centrifugal force is exerted at a first rotation angle position. Under the first centrifugal force, the flown out sample flows in an inlet of the stacking path and is separated into plural components and the components are stacked in the stacking path. When a second centrifugal force is exerted at a second rotation angle position, a component closest to the inlet of the stacking path flows into an inlet of the distributing path between the outlet of the intake path and the inlet of the stacking path, and is moved away from the inlet to be separated from the remainder of the components in the stacking path.
