An electric wire for improving the adhesion force between the adjacent winding wires of a coil is described. The electric wire of the present invention may include a conductive wire with a substantially quadrilateral cross-sectional shape. The electric wire further includes a first groove and a second groove positioned diagonally at two opposite corners of the quadrilateral along a longitudinal direction of the conductive wire. An adhesive pocket filled with an adhesive is sized to fit within each of the first and second grooves at diagonally arranged opposite corners.

Electric wire for high frequency, high voltage and large current

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.

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.

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. By applying this thin voice coil bobbin with the high strength, the speaker device applicable for the high power input can be obtained.

A tinsel wire is provided, which has a high mechanical strength as an electric power supplying conductor wire, hardly breaks with respect to a vibration of the diaphragm, has small dynamic resistance even in a vibrating atmosphere, has excellent flexing characteristics, thereby improving quality and reliability as a product, enables a thin designing of a product, and increases the freedom of the designing. The tinsel wire includes an assembled wire which includes a plurality of element wires each including core threads and a metal foil wound up around the core threads, the plurality of the element wires twisted, bundled or woven together constituting the assembled wire, wherein a cross section of the tinsel wire has a shape of a polygon selected from the group consisting of a quadrilateral, pentagon, hexagon and octagon.

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.

In a coil wire having a square sectional shape, arc-shaped chamfers are provided at four corners in the section of the square. The sectional area of the coil wire having the chamfers is set to at least 1.15 times as large as that of a circle having a diameter which is the same as the length of one side of the square.

Wire for coil

A process for treating a coil end is provided, by which upon automatic winding of the coil, an electric connection between a portion of a wire at the front or rear end of the coil and a terminal of a winding object by arc welding can be securely carried out. A stripping section strips an insulating coating off from the portions of the wire at the front and rear ends of the coil while the wire is wound around the winding object with the portions of the wire being bound to the terminal. Each portion of the wire, the insulating coating of which is stripped off, bound to the terminal is electrically connected to the terminal by arc welding.

An electric wire having a conductive portion with grooves on the surface thereof to increase a surface area of the conductive portion for enlarging the skin effect in high frequency current and enhancing the transmissibility and the space factor in high frequency current is provided. The conductive portionbeing made of an electric conductive material is formed on the surfacewith a convexo-concave surfaceto provide predetermined amount of groovesor concave portionshaving a predetermined section with a predetermined depth W extending in a direction of thickness or toward a center of the conductive portion on the surface of the conductive portion along lengthwise the conductive portion

An electric wireis moved in a moving direction at a desired speed. An insulating layer of varnish is formed on the outer surface of the electric wireby a device for applying the varnish. The device includes a rough-like containerand dropping means. The rough-like containeris located below the electric wirein the moving direction. The dropping meansis located for the electric wire above the container. A desired quantity of varnish is dropped from the dropping meanstoward the outer surface of the electric wirethrough a flow rate adjusting portion. The flow rate of the varnish is adjusted by the flow rate adjusting portion
