Abstract: An electronic component includes: a heat generator; a case containing therein a part or whole of the heat generator, the case including a body and a bottom; and a filler filling a gap between the heat generator and the case. The body is electrically insulating, and the bottom is electrically insulating and thermally conductive. Preferably, the bottom includes a heat dissipation sheet. The bottom may be made of a ceramic. Preferably, the body includes a main portion and a flange portion located at an end of the main portion that faces the bottom, the flange portion projecting outward or inward from the main portion.

Abstract: A transformer includes: a coil: a core enclosing the coil, the core including a first surface, a second surface adjoining the first surface, and a third surface opposite to the first surface and adjoining the second surface; and a plurality of radiator plates each of which covers a part of the core. The first and third surfaces are covered by different radiator plates of the plurality of radiator plates. Preferably, the core further includes a fourth surface opposite to the second surface and adjoining the third surface, and the second and fourth surfaces are covered by different radiator plates of the plurality of radiator plates.

Abstract: A cigarette filter comprises a cellulose ester tow and a cellulose acetate particle dispersed in the cellulose ester tow, and the cellulose acetate particle has the following particle size: not less than 90% by weight of the cellulose acetate particle pass through a sieve having an aperture size of 1.7 mm and fail to pass through a sieve having an aperture size of 0.10 mm, and these sieves are in accordance with JIS Z8801-1 2006.

Abstract: The present invention provides a molded sonic absorber excellent in sound absorption action for a sound with a wavelength in a human audible range. More specifically, the present invention provides a molded sonic absorber obtained by mixing: a chip of a cellulose acetate fiber as a component (A) ; a chip of a polyurethane foam as a component (B); and a urethane resin-based adhesive as a component (C), followed by compression molding.

Abstract: A device for deodorizing and drying a portion between toes used by putting it between toes.The device comprises two rod-shaped flexible fibrous elements or layers formed of a large number of fibers disposed parallel to the longitudinal axis of said layers, an air- and water-permeable flexible shell member being wound around said flexible fibrous layers such that a cavity is formed between the upper fibrous layer and the lower fibrous layer, and particulate substances having a hygroscopic function being housed in said cavity in a quantity corresponding to a part of a volume of said cavity.
