摘要： Provided is an insulated wire that can inhibit a decrease in adhesion between an insulation film including pores and a conductor. The insulated wire comprises a conductor having a long shape, and an insulation film including multiple pores and covering the conductor. The opening area ratio SR measured by a method below is 20% or less. The method of measuring the opening area ratio SR:peeling the insulation film from the conductor; obtaining a SEM image showing an interface on a conductor side in the insulation film peeled; calculating an area S1 of an observation region that is at least a part of the SEM image; and an area S2 of portions where the multiple pores are open in the observation region; and calculating the opening area ratio SR by the following Formula (1).


SR=(S2/S1)×100.  Formula (1)

摘要： Provided is a Fe—Al-based alloy vibration-damping component including 4.0 to 12.0% by mass of Al with the balance being Fe and inevitable impurities, having an average crystal grain size in the range of over 700 μm to 2,000 μm and a sectional defect rate of lower than 0.1%, and having an irregular sectional shape. Also provided is a method for manufacturing a Fe—Al-based alloy vibration-damping component. The method obtains a vibration-damping component having an irregular sectional shape, and includes a shaping step in which metal powder including 4.0 to 12.0% by mass of Al with the balance being Fe and inevitable impurities is melted and solidified using a heat source with a scanning rate set to 700 to 1700 mm/second to obtain a shaped product and an annealing step in which the shaped product is annealed at a temperature of 800 to 1200° C.

摘要： A silicon carbide ceramic honeycomb structure having large numbers of axially penetrating flow paths partitioned by porous silicon carbide cell walls, the cell walls having porosity of 35-50% and a median pore diameter of 8-18 μm, when a straight line C is drawn in parallel with the cell wall surface such that it passes a center in the direction of the thickness T of the cell wall, and straight lines are drawn in parallel with the straight line C such that they are separate from the straight line C by ±T/5 and ±2T/5 in the thickness direction of the cell wall, to measure the lengths (pore widths) of pore portions crossing each straight line, and the number of pores crossing each straight line, in a cell wall cross section perpendicular to the axial direction, an average pore width W determined by averaging the lengths (pore widths) of all measured pore portions being 10-25 μm, and the number N of pores per length determined by dividing the total number of the measured pores by the total length of the straight lines used for measurement being 20-40/mm.

摘要： An electric wire connection structure is provided with a plurality of insulated electric wires with each core wire being covered with an insulation coating. The core wires are connected to pads provided on a substrate. The plurality of insulated electric wires are arranged parallel to each other on the substrate along a predetermined alignment direction. The insulation coatings are removed in part in respective longitudinal directions to expose the core wires, and exposed portions of the core wires are connected to the pads, respectively. The exposed portions of the core wires are arranged along an inclined direction inclined with respect to a longitudinal direction of the plurality of insulated electric wires and the alignment direction.
