Abstract: The present invention provides a technology, which is capable of easily switching between the vacuum function and the blower function of the vacuum cleaner with a simple configuration, and is also capable of effectively utilizing the blower function even in the various situations. Typical air suction/injection device is configured that the interior of the main unit constitutes a main passage of air, and the interior of an injection passage section provided in the main body constitutes a sub-passage. Once a suctioned airstream is created in the main passage, a power fan inside of a suction chamber is rotated, and in conjunction with such a rotation, an injection fan is rotated so that an injecting airstream is created in the sub-passage. In such case, a passage switching section composed of a valve member provided in the location of joining the main passage and the sub-passage is switched to easily switch between a creation of an injecting airstream and a creation of a suctioned airstream.

Abstract: The coil component comprises a primary coil, and a first secondary coil and a second secondary coil which are opposed to the primary coil. A first terminal is a terminal of the first secondary coil, that is a terminal for connection to one end of a lamp, and a second terminal is a terminal of the second secondary coil, that is a terminal for connection to the other end of the lamp. The first secondary coil and the second secondary coil are coaxially disposed, and the first terminal and the second terminal are reverse in polarity.

Abstract: A transformer arranged to be used for an illuminating apparatus includes a closed-magnetic-circuit core, a primary coil wounded around the closed-magnetic-circuit core, and multiple secondary coils wounded around the closed-magnetic-circuit core. The secondary coils include first ends and second ends. The illuminating apparatus includes multiple discharge lamps. Each of the first ends and each of the second ends of each secondary coil are connected to different discharge lamps.

Abstract: A transformer arranged to be used for an illuminating apparatus includes a closed-magnetic-circuit core, a primary coil wounded around the closed-magnetic-circuit core, and plural secondary coils wounded around the closed-magnetic-circuit core. The plural secondary coils includ respective first ends and respective second ends. The illuminating apparatus includes plural discharge lamps. Each of the respective first ends and each of the respective second ends are arranged to be connected to discharge lamps, out of the plurality of discharge lamps, different from each other. This transformer prevents variation of lighting timings of discharge lamps, accordingly providing an illuminating apparatus and a display apparatus having little brightness variation.

Abstract: According to the present invention, there is provided a security thread whose existence is not clarified, which is prevented beforehand from being removed, which can be attached even to a form of a commodity heretofore regarded as difficult, and whose use purpose range is enlarged, and the security thread can be constituted by a core member comprising a soft magnetic fiber (1) or the soft magnetic fiber and a core thread (4), and a cover member (2, 3) comprising a nonmetal material to cover the core member, constituted by covering the core member comprising the soft magnetic fiber or the soft magnetic fiber and core thread and a semi-hard magnetic material (10?) with the cover member, or constituted by covering the soft magnetic fiber or the core member comprising the soft magnetic fiber and a thermal welding thread (9) with the cover member.

Abstract: A molded transformer includes a transformer body including a coil bobbin having a spool having a central through-hole and a collar at each of two ends thereof, and a conductive wire, such as a copper wire, wound around the spool, and an EE type or EI type ferrite core which is inserted into the coil bobbin; and a thermoplastic resin for molding the transformer body in such a manner that only a terminal portion used for mounting is exposed through the resin. The resin has a low molecular weight, ensuring a low molding stress and a low melting viscosity.

Abstract: An encased transformer that comprises a bobbin including a plastic-molded cylindrical portion and upper and lower collars formed respectively at upper and lower ends of the cylindrical portion, a magnetic element extending centrally through the cylindrical portion, primary and secondary coils wound round the outer periphery of the cylindrical portion, comb-shaped metals terminal formed on the pair of lower collars by insert molding, the comb-shaped portion of each metal terminal being bent at generally right angles, the metal terminals being further bent at right angles and outwardly horizontally at an end portion thereof so that the metal terminal is substantially Z-shaped, a straight portion of the metal terminal positioned midways of the Z-shaped being fixedly held in position between the inner wall of a case and a frame wall having recessed terminal grooves into which are individually fitted metal terminals provided in a plastic square bottom plate.
