Abstract: In an electromagnetic clutch, a rotor includes a cover portion that covers a radially outer end of an armature from a radially outer side. The cover portion, the radially outer end of the armature, and a wall of the rotor define a discharge passage that is formed into a ring shape centered on a rotating shaft and is open on a first end side in an axis line direction for discharging abrasion powder generated by friction between walls. The cover portion includes a tapered surface that is shaped such that an area in a cross sectional plane of the discharge passage which is orthogonal to an axis of the rotating shaft becomes larger toward the first end side in the axis line direction.

Abstract: A dish washer/dryer includes a washing tub for accommodating an object to be washed, a washing section for washing the object to be washed, a heater for heating washing water, an exhaust port for discharging moisture inside the washing tub, an air blower for blowing outside-air, a mixing section disposed at an upstream side of the exhaust port and mixing the outside-air with washing-tub-inside-air, and an air volume distribution section for changing the feeding ratio of outside-air into the washing tub and the mixing section. This configuration provides a dish washer/dryer, in which a sufficient amount of outside-air is mixed with exhaust air in the washing tub so as to promote the temperature reduction of the exhaust air and the reduction of the moisture content in the exhaust air during drying operation, thereby enhancing the comfort of the exhaust air.

Abstract: The present invention is directed to a speaker using lightweight, highly rigid diaphragm having excellent frequency characteristic and improving resistance to environment (including resistance to UV and resistance to fading). For this end, the speaker utilizes a cone-shaped diaphragm made from foamed or cellular resin such as polyethylene terephthalate (PET) resin or polyethylene naphthalate (PEN) resin with 30 ?m average cell size. The use of such cone-shaped diaphragm is effective to improve sound quality of the speaker.
