Abstract: A gap control part controls a clamping device so that mating surfaces in a die face each other across a gap, and thereby a cavity and an external part of the die communicate across the gap. A molten metal feed control part controls a molten metal feed device so as to feed molten metal into a sleeve when the gap is being maintained. An injection control part controls an injection device so as to start a forward movement of a plunger at a time when the gap is maintained and there is the molten metal in the sleeve. A clamping control part controls a clamping device so as to make the mating surfaces abut against each other to eliminate the gap after the forward movement of the plunger is started and before the molten metal reaches a molten metal surface height at which the molten metal flows into the gap.

Abstract: Provided is a magnetic body and a magnetic element that can be used in a high temperature environment of 180° C. and are excellent in heat resistance. The magnetic body according to an aspect of the present invention includes an iron alloy powder having an inorganic insulating layer on the surface thereof and a resin cured product, and contains 4 to 10 parts by mass of Si in 100 parts by mass of the iron alloy powder.

Abstract: A test device is used to test photosensitivity of a skin. The test device is provided with an irradiation unit including a plurality of light irradiation units arranged in a first direction. The plurality of light irradiation units output, in a second direction intersecting the first direction, irradiation light beams that mutually differ at least in one of wavelength characteristics and intensity. The irradiation unit is configured such that intensities of the irradiation light beams output from the plurality of light irradiation units are progressively smaller in the first direction.
