Abstract: A heat sink mounting device according to the present invention can secure a mounting space of the heat sink sufficiently, mount a heat sink with large capacity, and use a main board in common even when a dual central processing unit (CPU) is constituted by extension of CPU. A main board has an opening. A CPU is mounted on a main surface of the main board. A sub board is attached on the main surface of the main board to permit the opening to be covered. An extension CPU is mounted on the sub board through the opening from a rear face side of the main board. A first heat sink is mounted in the main surface side of the main board to permit the CPU and the opening to be covered. A second heat sink is mounted in the rear face side of the main board to permit the extension CPU and the opening to be covered.

Abstract: A method of designing the form of a cable clamp and cables using a three-dimensional CAD system for easily designing the form of the cables passing through the cable clamp is disclosed. According to the method, the cable clamp is checked by comparing the area necessary for clamping the cables with the inner-diameter area of the cable clamp; the control points related to the cable clamp are designated; and the data of the designated control points are added to the data of control points assigned to each cable in advance. Therefore, the form of the clamped portion of each cable can be simultaneously determined together with the forms of the other portions of the cable, so that the designer can execute the verification of the cable clamp and the design of the cable forms in a short time.

Abstract: A product selling system is provided that can be precisely grasp a feeling of fitting with a body on the screen even when apparel product has extensibility and workability. The product selling system comprises a body image creator for creating, based on information on a body type of purchaser, a three-dimensional image of the body of said purchaser; a product information provider for providing information on a product supplied by a seller; and an image synthesizer for creating a three-dimensional image based on the product information and then synthesizing the created three-dimensional image with the three-dimensional image of the purchaser. The product information supplied by the product information provider includes at least information on design of the product, measurements of respective portions of the product, a degree of extension (if a product has extensibility), and adjustability and an allowable work range (if a size of a product is workable).
