摘要： A loudspeaker comprising at least one magnet 27, a yoke 24 fixed to a bottom surface of the magnet, a flat plate 26 fixed on an upper surface of the magnet, a magnetic circuit 29 having a magnetic gap 28 formed between the plate and the yoke, and a flat diaphragm 23 provided with a coil 21 disposed above the magnetic gap. The magnet has a width greater than that of the plate, and at least a part of the upper surface of the magnet is exposed so that it directly faces the diaphragm. According to the structure of the present invention, a larger volume magnet can be used without increasing the size of the magnetic circuit. Furthermore, as magnetic flux can be concentrated in an upper region of the magnetic gap, the magnetic circuit becomes efficient and compact. Thus a compact and high-efficiency loudspeaker for high frequency sound reproduction can be provided.

摘要： A power transmission apparatus comprising a pulley 1 and a hub 2 is disclosed. The hub 2 includes an inner hub 21 fixed on a rotary shaft 4 and an elastic member 23 coupled over a joint length L to the outer periphery of the inner hub 21. Elastic member 23 includes a hub-side engaging portion having a series of protrusions arranged in a ring and a cylindrical portion connecting the hub-side engaging portion and the inner hub. Pulley 1 has a pulley-side engaging portion having a series of depressions fitted on the hub-side engaging portion. The engagement between hub-side engaging portion 235 and pulley-side engaging portion 14 forms a torque transmission structure of hub 2 and pulley 1. An axial length TL of a torque transmission surface TS formed by hub-side engaging portion 235 and pulley-side engaging portion 14 in contact with each other is larger than joint length L between the cylindrical portion and inner hub 21. Axial length TL, when projected in the radial direction, is partially overlapped with joint length L.

摘要： 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.

摘要： 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 μm average cell size. The use of such cone-shaped diaphragm is effective to improve sound quality of the speaker.

摘要： A highly stiff end mill comprising a shank, a plurality of helix cutting edges on the periphery of the end mill, the end mill being characterized in that a radial rake angle of the helix cutting edges in a cross section perpendicular to the longitudinal axis of the end mill is set in the range of -29.degree. to 0.degree. and a core diameter of the end mill is set in the range of 70 to 90% of the outside diameter of the end mill.By selectively determining the negative rake angle in the range described above, this end mill is applicable to hard materials and has general-purpose properties. The improper factors of the end mill, such as increased cutting resistance, can be compensated for by setting the core diameter thereof to the range described above. This end mill is also structured to be able to cut materials with less hardness values as well as hard materials, thereby covering a wide range of applications.
