Abstract: Disclosed is a speaker comprising a frame connected with a magnetic circuit having a magnetic gap, a voice coil disposed adjacent to but not in contact with an upper side of the magnetic circuit, and a diaphragm bonded to a circumferential edge of the frame, wherein the frame and the diaphragm are configured into such peripheral shapes that conform to a mounting space allowed for the speaker inside an apparatus. This structure allows an external shape of the speaker to be freely configurable according to a limited space, yet the irregularly-shaped diaphragm is capable of being driven with an uniform amplitude, thereby providing an advantage of down-sizing and high performance.

Abstract: A chip-type solid electrolytic capacitor has a four-terminal structure. The chip-type solid electrolytic capacitor includes capacitor elements laminated such that anode electrodes face alternately in opposite directions; a pair of anode terminals opposing each other; and a pair of cathode terminals opposing each other. The magnetic fluxes generated by current passing between respective terminals are mutually cancelled, thus allowing ESL to be drastically reduced. Further reduction of ESL is feasible by shortening the distance between the terminals as much as possible so as to reduce the current loop area.

Abstract: The invention relates to a capacitor device comprising the combination of a cylindrical capacitor and a holder for holding the capacitor in a sideways position. The holder includes a capacitor holding part that has an opening at the top and is arc-shaped in cross section, and a mounting part for mounting the holder itself to another device. The capacitor is held in a sideways position in the holding part of the holder with a heat shrinking resin tube interposed therebetween. Accordingly, the height of the capacitor device is reduced, so that the size of the capacitor device can be reduced. In addition, the connection distance between the capacitor device and another electronic device is shortened, so that the inductance can be made smaller.

Abstract: A capacitor is provided to overcome the following problem: when plural capacitors are linked, a large coupling space is required because an anode and a cathode are brought out through the opposite ends, so that downsizing the capacitors is difficult. The capacitor also allows easy electrical and mechanical coupling, reducing the coupling space and unnecessary resistance. A structure of the capacitor is this: Capacitor element (2) is enclosed in mechanical housing (3) of which opening is sealed by terminal plate (4). Terminal slip (5), which includes rib (5b) to be coupled to a first electrode of capacitor element (2) and terminal (5a), is insert-molded into terminal plate (4). A second electrode is coupled to an inner bottom face of metal housing (3). One of the anode or the cathode is brought out through terminal (5a), and the remaining one is brought out through metal housing (3), thus a lower resistance is expected.

Abstract: Disclosed is an aluminum electrolytic capacitor, wherein each of anode and cathode foils is joined to a corresponding portion of a leader line through at least two caulked joint sections formed at each of the opposite ends of the flat portion, and a plurality of pressure-welded joint sections formed between the respective caulked joint sections at the opposite ends. The chaulked joint sections formed at each of the opposite ends of the portion provide a high joint strength. Further, the pressure-welded joint sections formed between the respective caulked-join sections at the opposite ends of the portion allow an electrical connection between the foil and the leader line to be stably obtained at a low resistance. This joint structure can, therefore, be applied to small-size capacitors which have not been able to be obtained by using only caulked joint, to achieve an aluminum electrolytic capacitor having a sufficient joint strength and a highly reliable electrical connection.
