摘要:
Soft magnetic powder of Fe—Al—Si system of which magnetostrictive constant &lgr; takes a positive value at the room temperature is employed to produce a magnetic composite article so that a temperature characteristic of core-loss of the article takes a negative value at the room temperature. Excellent magnetic characteristics such as a low core-loss and a high permeability can be obtained at a high frequency band.

A choke coil for preventing harmonic distortions having a plurality of laminated iron core sheets formed into a core. A first coil is wound around a first limb of a first core, and a second coil is wound around a first limb of a second core. A third coil is wound around the second limb of both the first core and the second core, and the second core is disposed within the magnetic circuit of the first magnetic core. The iron core sheets have embossments formed on a front and back side for fitting the iron core sheets together. The embossments have longitudinal sides formed orthogonally to the direction of magnetic fluxes in the core, and may be inwardly inclined to face each other.

According to one embodiment, a semiconductor device includes a casing, a semiconductor element, a terminal and a screw member. The semiconductor element is housed within the casing. The terminal is electrically connected to the semiconductor element, and has an externally projecting part extending out of the casing. The screw member is movably provided along a surface of the casing between the externally projecting part and the casing, and fixes an external terminal to the externally projecting part.

Here is disclosed a disposable diaper, which includes a liquid-absorbent zone in a crotch region having first through fourth sections. A stiffness of the first and second sections formed from top- and backsheets is lower than a stiffness of the third and fourth sections formed from the top- and backsheets and an absorent core. Stretchably elastic members extending in a longitudinal direction are contractibly attached to the fourth section. A liquid-absorbent zone in the crotch region is formed with a concavity (feces pocket) as the fourth section contract in the longitudinal direction under a contractile force of the elastic members.

A disposable absorbent undergarment includes a liquid-permeable topsheet, a liquid-impermeable backsheet and a absorbent core disposed therebetween. The backsheet consists of a breathable plastic film and a breathable fibrous sheet integrally laminated with an outer surface of the breathable plastic film. The breathable fibrous sheet consists of at least a first component layer and a second component layer being in contact with the first component layer. The first component layer has a wettability with body fluids higher than that of the second component layer.

A semiconductor device includes: a semiconductor chip mounting substrate, a control circuit board, a power terminal holder and a semi-fixing member. The semiconductor chip mounting substrate includes a substrate, a semiconductor chip provided on a first major surface of the substrate, and a first and second semiconductor chip connection electrodes. The control circuit board is provided generally in parallel to the first major surface and includes a control circuit, a control signal terminal connected to the control circuit, and a through hole extending in a direction generally perpendicular to the first major surface. The power terminal holder is provided on opposite side of the control circuit board from the semiconductor chip mounting substrate and includes a power terminal. The semi-fixing member includes a shank portion and an end portion. The shank portion is fixed to the power terminal holder and penetrates through the through hole. A cross section of the shank portion in a plane orthogonal to the extending direction of the through hole is smaller than a size of the through hole. The end portion is connected to a tip of the shank portion. A cross section of the end portion in the plane is larger than the size of the through hole. The first semiconductor chip connection electrode is connected to a first terminal of the semiconductor chip and the control signal terminal. The second semiconductor chip connection electrode is connected to a second terminal of the semiconductor chip and the power terminal.
