Abstract

In an electric current sensor device 10, a magnetic core 12 is annular and a primary conductor 50 is inserted therein. A load 143 of a drive circuit 14 is a secondary conductor 151 that is wound around the magnetic core 12. A detection resistor 16 converts a current flowing in the secondary conductor 151 into a voltage and generates, at one end thereof, a detection voltage. A drive unit 141 switches the direction of a current flowing in the secondary conductor 151 on the basis of pulse signals. A detection unit 20 detects a current which has flowed in the primary conductor 50 on the basis of the duty ratio of the pulse signals. A pulse signal generation circuit 18 monitors the detection voltage generated at one end of the detection resistor 16 and inverts on/off of the pulse signals. A clock generation unit 201 of the detection unit 20 generates clock signals at a predetermined period. A counter 211 counts the duty ratio of the pulse signals using clock signals.

Abstract

This alloy powder production device comprises a substrate, at least one nozzle, and at least one alloy supply part. The nozzle forms a liquid film having a predetermined thickness by supplying a high-speed fluid formed from a cooling liquid onto the substrate in such a manner as to apply a predetermined acceleration to the liquid film along a thickness direction. The alloy supply part supplies a molten alloy to the liquid film without dividing same into a size equal to or less than a predetermined thickness. Particles are formed by dividing the molten alloy into a size equal to or less than the predetermined thickness by means of the high-speed fluid, and the particles are cooled in a condition in which the particles are retained in the liquid film by means of the predetermined acceleration and kept in contact with the high-speed fluid.

The first core 32 is a pressed powder core. The first core 32 and the second core 34 form a magnetic path in which a magnetic flux circulates. In a plane including the magnetic path, the coil 200 forms two or more winding windows. In the same plane, the first core 32 is in contact with the entirety of one side that extends in a second direction of each of the winding windows, and protrudes from both ends of the one side in at least one of the winding windows. In the same plane, the second core 34 is in contact with three sides other than the one side of each of the winding windows. The surface resistance between two points, which are spaced apart by 20 mm in the first core, is 5 Ω or greater after a high-temperature storage test is performed. The driving frequency of the coil component 10 is 20 kHz or higher.
