Abstract: A motor-operated valve has a rotor unit in a can, and is rotationally driven by a stator unit. The rotation of the rotor unit is transmitted to a screw feed member. A stem member fixed to a valve body is engaged threadedly with the screw feed member by a first screw portion. At the same time, the screw feed member is engaged threadedly with an external thread portion fixed to a valve stem by the second screw portion. The first screw portion and the second screw portion constitute a differential screw mechanism, and feeds the valve stem according to a difference in pitch.

The base sheet includes a breathable but liquid-impervious plastic film and a fibrous nonwoven fabric joined to the plastic film to define an undergarment side surface, the base sheet having a total luminous transmittance in a range between 60 and 85%.

Abstract: A disposable diaper includes a cover member having an hourglass-shape and a-separate liquid-absorbent member composed of a liquid-permeable topsheet, a liquid-impermeable backsheet and a liquid-absorbent core. The cover member has an elastic stretchability along the upper ends of front and waist regions, and these front and rear waist regions are connected or connectable along transversely opposite side edges thereof. The liquid-absorbent member includes first and second elastically stretchable members that extend circumferentially across portions of the front and rear waist regions lying immediately above the crotch region. Longitudinally opposite ends of these elastically stretchable members are bonded to the transversely opposite side edges of the cover member.

Abstract: A fan-motor-incorporated heat sink effectively supplies cooling air flow in a thin electronic device having limited space above the heat sink. The heat sink enables air intake above the heat sink by positioning a fan, the fins of a heat sink substrate and the side wall of the substrate lower than the fan driving unit. The heat sink substrate and the fins are formed such that air is exhausted only in one direction. A cover is provided on the side of the heat sink substrate on which the fan driving unit is mounted and to which air is taken in to prevent exhausted air from being taken in. The structure of the electronic device is positioned close to the upper surface of the fan driving unit on the heat sink. Thus, the heat sink can be installed on a thin electronic device while improving the cooling of a heat emitting element.
