Abstract: A coil assembly includes a bobbin and a coil wound around the bobbin. The bobbin includes a terminal configured to hold a winding start part or a winding finish part of the coil. The terminal includes a first holding part configured to hold a first part of the winding start part or the winding finish part, and a second holding part configured to hold a second part of the winding start part or the winding finish part, the second part being apart from the first part.

Abstract: An electric wire contains a conductive wire having at least a groove structured on the surface of the conductive wire, and an additional wire to be filled into the groove. The groove is provided on an outer surface of the conductive wire along a longitudinal direction of the conductive wire. The additional wire is inserted in the groove.

Abstract: A furniture including at least one leg, said at least one leg includes a cavity, a speaker, and at least one hole connecting the cavity with outside of the leg. The cavity is provided inside the leg while the speaker is provided inside the cavity or toward the cavity.

Abstract: An organic EL display device or a lighting device is covered by sealing the top and bottom, left and right, front and back, that is the entire body and periphery of the panel, with an air-impermeable sealing resin. Dipping the substrate plate or printing the sealing resin onto the substrate plate is applied to the substrate plate excluding the display area and light emitting area of the organic EL panel to block intrusion of air and moisture that affect the life of the organic EL element. With this, the life of an organic EL panel can be extended, and large screen size and mass production of panel can be also easily accomplished.

Abstract: An exciter assembly includes a magnetostriction element and a holder encasing the magnetostriction element. The holder is provided with a groove which is positioned on at least a part of an outer circumstance of the holder. The exciter according to embodiments of the present invention is capable of generating a large sound and may be installed easily. A method of its installation and an acoustic transmission member including said exciter are also provided.

Abstract: A voice coil bobbin is formed by skinpass rolling of pure titanium. A manufacturing method of a voice coil bobbin includes a process which manufactures a rolled pure titanium material, a process which executes skinpass rolling of the rolled material, and a process which forms the rolled material after the skinpass rolling to manufacture the voice coil bobbin. For example, the rolled pure titanium material is manufactured by a standard manufacturing process of a normal rolled material defined by JISH4600, and the cold rolling for the purpose of the strengthening is executed. The cold rolling is executed under a condition of a rolling ratio equal to or larger than 60%. Thereby, it becomes possible to obtain double hardness of JIS No. 1-kind titanium material (TR270C) and tensile strength larger than double of the JIS No. 1-kind titanium material (TR270C) and close to 6-4 titanium.

Abstract: Wire winding is performed while a guide member is regulating a winding position of a regular-square wire (for example, while moving the wire member in an axial direction in accordance with the number of winding (turns) of the rectangular cross section wire member) such that a side surface of the regular-square wire already wound on an outer periphery of a cylindrical part of a bobbin closely adheres to a side surface of the regular-square wire about to be wound. Thus, it is possible to form a coil having an excellent characteristic by winding the regular-square wire on the without making a gap.

Abstract: In a coil wire having a square sectional shape, arc-shaped chamfers are provided at four corners in the section of the square.
