    Abstract: An object of the present invention is to provide a polarized vinylidene fluoride/tetrafluoroethylene copolymer resin film that can significantly reduce, when used as an optical film, the deterioration of the quality of video or still images formed by display elements.The present invention provides a polarized vinylidene fluoride/tetrafluoroethylene copolymer resin film having 2,000 or fewer spot defects per m2, the number of spot defects being measured by a defect measurement method; the method using an surface inspection system in which a CCD camera is placed so as to detect defects at an angle of 45 degrees relative to an LED source, defects of the film are read within a rectangular range of 300 mm in a width direction (the direction perpendicular to the scanning direction), and 150 mm in a machine direction (the scanning direction), while the film is scanned under the camera at a rate of 20 m/min; wherein first, defects having a bright area of 1.5 mm2 or less and a dark area of 1.4 mm2 or less are selected; and next, in order to remove defects resulting from causes other than a corona treatment contained in these defects, a circumscribed rectangle of defect is set so as to have two sides along the scanning direction, and the number of only defects that have a circumscribed width of 2.88 mm or less, a circumscribed length of 2.3 mm or less, an aspect ratio of −39 to +27, an occupancy area ratio in the circumscribing rectangle of 4,000 to 6,950, and an area ratio of −3,100 to +5,200, is automatically counted as spot defects by the surface inspection system.

    Abstract: An ion/ozone wind generation device includes a plurality of electrode pairs having a needle-shaped electrode and an opposite electrode, ions, ozone, and ion wind being generated using corona discharge by generating a potential difference between the respective electrode pairs. In this device, the opposite electrode in each of the electrode pairs is formed into a planar and annular or spiral shape, a main electrode pair as a pair of electrodes and a plurality of sub-electrode pairs as electrode pairs in which the opposite electrodes are regularly located adjacent or proximate to each other so as to surround the opposite electrode in the main electrode pair along an outer circumference of the opposite electrode in the main electrode pair are provided, and planar normal vectors in all the opposite electrodes are directed in substantially the same directions.

    Abstract: The invention relates to a corona ignition device for igniting fuel in an internal combustion engine by means of a corona discharge, comprising a central electrode, an insulator, into which the central electrode plugs, a housing, into which the insulator plugs, a bobbin, onto which a coil which is attached to the central electrode is wound, and a shield cap, which is plugged onto an end portion of the bobbin facing the insulator. According to the invention, a portion of the central electrode protrudes through a bottom of the shield cap, or a circumferential wall of the shield cap has one or more slots, or the shield cap has a circumferential wall, which protrudes only on one side beyond the bottom of the shield cap only on one side.

    Abstract: A reversed-assembled corona igniter including an insulator, central electrode, and metal shell, wherein an outer diameter of the insulator increases adjacent a lower end of the metal shell to achieve an electrical advantage is provided. In addition, the insulator maintains strength because is not placed under tension during or after assembly, or once disposed in an engine. To achieve the increase in insulator outer diameter, the insulator includes a lower shoulder adjacent the shell firing end. An intermediate part, such as braze and/or a metal ring, is disposed between the insulator outer surface and the shell adjacent the shell firing end. To prevent tension in the insulator, the insulator can be supported at only one location between the insulator upper end and the insulator lower end, for example along the intermediate part.

    Abstract translation: 包括绝缘体，中心电极和金属壳的反向组装的电晕点火器，其中提供了绝缘体的外径相邻于金属壳的下端增加以实现电气优点。 此外，绝缘体保持强度，因为在组装期间或组装之后未被置于张力下，或者一旦设置在发动机中。 为了实现绝缘体外径的增加，绝缘体包括邻近壳体射出端的下肩部。 诸如钎焊和/或金属环的中间部分设置在绝缘体外表面和壳体射出端附近的外壳之间。 为了防止绝缘体中的张力，绝缘体可以仅在绝缘体上端和绝缘体下端之间的一个位置被支撑，例如沿着中间部分。
