Abstract: The battery pack includes: a plurality of battery cells each formed by closing an opening of a bottomed cylindrical outer can with a sealing plate; a battery holder to hold the plurality of battery cells in a mutually parallel attitude and hold electrode terminals provided at both ends of each battery cell in an attitude disposing on a same plane; and an outer case to house a battery assembly formed by holding the plurality of battery cells in the battery holder. The battery holder includes: a holding part to hold the ends of the plurality of battery cells along outer peripheral surfaces of the outer cans; and a cover on an end surface side of the plurality of battery cells held by the holding part. When the battery cell is abnormal, the cover is deteriorated by energy of a jetting body jetted from an end surface of the battery cell.

Abstract: Battery pack includes: a plurality of chargeable/dischargeable cylindrical cells; battery holder in which the plurality of cylindrical cells are disposed; and thermally conductive resin that closely adheres to cylindrical cells, which are stored in battery holder, in a thermally coupled state above battery holder. Battery holder includes: bottom plate including a plurality of holding grooves in which cylindrical cells are disposed; and partition walls that are disposed between holding grooves and between adjacent cylindrical cells. Partition walls are lower than the diameter of cylindrical cells disposed in holding grooves, thermally conductive resin is disposed between adjacent cylindrical cells above partition walls, and thermally conductive resin interconnects adjacent cylindrical cells.

Abstract: A battery pack detachably mounted in a device for supplying power to the device to operate the device includes at least one rechargeable secondary battery (1), a battery case (31) housing the rechargeable secondary battery (1), a mounting mechanism for mechanically mounting the battery case (31) in the device, an electrical connection connected electrically to the device for supplying power to the device, and a pack circuit board (74) securing the electrical connection. The battery case (31) is divided into a first casing and a second casing, the pack circuit board (74) is secured to the inside surface of the first casing, and the mounting mechanism is installed so the mounting mechanism is at least partially exposed on the surface of the first casing.

Abstract: The purpose of the present invention is to provide simpler and more reliable electrical wiring than a lead wire. A battery pack includes at least one rechargeable secondary battery (1), a battery holder (70) for housing the secondary battery (1) in a predetermined position, a pack circuit board (74) having a mounted electronic circuit for monitoring the secondary battery (1), and an electrical connection wire (85) for electrically wiring the pack circuit board (74). Here, the electrical connection wire (85) is a bent metal wire. Because wiring is realized using metal wire, and the metal connection is secured after the wiring has been completed, movement and deformation due to vibrations and other factors, such as that which occurs in the case of conventional lead wires, are avoided, and reliability can be improved.

Abstract: A hard coat film comprising a substrate film and a hard coat layer disposed at least on one face of the substrate film, wherein the hard coat layer comprises 100 parts by weight of (A) a resin of an ionizing radiation curing type and 0.1 to 10 parts by weight of (B) a nonionic surfactant. The hard coat film is used for protection of surfaces such as the surface of touch panels and displays. Attachment of finger prints during input operations by fingers on the surfaces is suppressed and the attached finger prints can be easily wiped out. Scratch resistance and wear resistance of conventional hard coat films are retained.

Abstract: This invention is directed to the prevention of the deterioration of the accuracy in component mounting by suppressing the temperature rise of the moving member as much as possible by cooling the moving member, which is the heat source of a linear motor. The moving member 48 of the linear motor 14 is configured in the following manner for achieving the objective of this invention. That is, the heat dissipation portion, the axis 17 made of the material with efficient thermal conduction such as aluminum, pierces through the iron core 18 around which coils 20 are wound. The moving member except a part of the axis 17 is molded with synthetic resin, and at one end of the axis 17, the heat dissipation fin 19 which makes heat dissipation area larger is formed. And this heat dissipation fin 19 is placed to face the air exhaust port 67.

Abstract: A hard coat film exhibits excellent scratch resistance and wear resistance, provides the property for preventing attachment of finger prints and the property for removal of finger prints by a simple operation, is excellent in retaining these properties, exhibits excellent solvent resistance and is advantageously used as the hard coat film for touch panels and the hard coat film for protecting various types of display. The hard coat film comprises a transparent substrate film and a hard coat layer disposed at least on one face of the substrate film, wherein the hard coat layer comprises a cured product of a resin composition sensitive to an ionizing radiation which comprises a polymerizable surfactant.

Abstract: An anti-glare hard coat film comprising an anti-glare hard coat layer disposed on at least one face of a transparent substrate film, wherein the anti-glare hard coat layer comprises (A) a resin cured by an ionizing radiation and, per 100 parts by weight of the cured resin, 0.2 to 10 parts by weight of (B) fine particles of silica and 1 to 20 parts by weight of (C) fine particles of a silicone resin. When this film is used for various displays, the excellent anti-glare property can be provided without decreasing the highly fine quality of displayed images. This film is also advantageously used as a protective film having a great surface hardness.
