Abstract: Machining of the present invention is machining of polishing work to be polished by movement of polishing sheet relative to work, in a state where polishing sheet is in contact with a surface of work to be polished. In the machining, work is arranged in contact with polishing sheet in a state where work is sandwiched between first simultaneous machining material with hardness lower than that of work, and second simultaneous machining material with hardness higher than that of work, and work is polished by relative movement of polishing sheet from first simultaneous machining material toward second simultaneous machining material.

Abstract: An optical disk retrieval device separates and retrieves a plurality of loaded optical disks one by one in order from top. The device includes: a base that loads the plurality of optical disks; A pulling-up unit for pulling up the top optical disk of the plurality of loaded optical disks; a separation member that can cause a force to act on an inner wall of an inner hole of a plate-like member having the inner hole; and A separation member elevating unit for moving the separation member in a vertical direction. The pulling-up unit lifts the top optical disk upward, and the separation member elevating unit passes the separation member through an inner circumferential hole of the top optical disk lifted by the pulling-up unit from an upper side to a lower side. The separation member causes the force to act on the inner wall of the inner hole of the plate-like member adhering directly beneath the top optical disk to thereby separate the plate-like member.

Abstract: A heating apparatus includes a film feed mechanism, a laser light source, a laser irradiation component, and a laser controller. The film feed mechanism has a film contact surface that contacts with one surface of a film material, and moves the film material in the lengthwise direction of the film material. The laser irradiation component emits a laser beam toward the film contact surface. The film contact surface has a first contact surface and second contact surfaces, a material forming the first surface having a different thermal conductivity that a material forming the second surfaces. The second contact surfaces are disposed at positions that come into contact with the ends of the film material in the width direction, while the first contact surface is disposed between the second contact surfaces. The material forming the first contact surface has a lower thermal conductivity than the material forming the second contact surfaces.

Abstract: An object of the present invention is to provide a reflection sheet which can improve reflection property and concealing property, and a backlight unit capable of attempting the improvement of brightness and the prevention of lack in uniformity of the brightness through decreasing loss of rays of light using said reflection sheet. Specifically, disclosed is a reflection sheet which is provided to the back face side of the backlight unit to reduce the loss of rays of light to the back face side, and which may include a substrate sheet layer made of a white synthetic resin and a highly concealing layer overlaid to the back face side of the substrate sheet layer, wherein the highly concealing layer has luminosity (L*) of equal to or greater than 95. In addition, further disclosed is a backlight unit for use in a liquid crystal display device including this reflection sheet to the back face side of an optical waveguide plate.

Abstract: A reflection sheet which can prevent scratches on a back face of an optical waveguide plate, and a backlight unit capable of attempting the improvement of brightness and the uniformization of the brightness using the reflection sheet. The reflection sheet includes a substrate sheet made of a white synthetic resin and a scratchproof layer overlaid to the front face side of this substrate sheet, wherein the scratchproof layer has flexible protrusions on its front face in a substantially uniform manner. The scratchproof layer includes a binder and beads dispersed in the binder. Flexible elastomer material which constitutes the beads is preferably flexible polyurethane or a silicone rubber.

Abstract: The present invention pertains to a method wherein a concavoconvex cutting line is applied repetitively in a periodical way in the longitudinal direction of a continuous first web to form first and second partial webs; said first partial web is offset with respect to said second partial web in the longitudinal direction by a prescribed interval so that the concave edges and the convex edges of the first and second partial webs are positioned opposite to and aligned with each other, whereafter a continuous second web is used to connect the outside edges opposite to the said aligned concave and convex edge portions of the first and second partial webs, and as the second web is bonded with the outside edges of the partial webs a composite web is formed, following which the first and second partial webs of the composite web are spread apart.

Abstract: The fly wheel and the ignition coil are set on the set jig with a comparatively large space left therebetween so that the two do not adhere to each other during the placement thereof. After the fly wheel and the ignition coil are placed on the set jig and are delivered to the two holding means of the assembling jig, a large space is maintained between the fly wheel and the ignition coil so that when the fly wheel is turned to be aligned, there is no magnetic force acting between the fly wheel and the ignition coil. Thus, the fly wheel can be easily assembled to the crankshaft. Thereafter, the ignition coil is brought to approach the fly wheel and is assembled to the engine main body where it is located at its normal facing position in relation to the fly wheel.
