Abstract: A polyamide resin molded body is formed by a resin composition having a (B) fluorine series resin within a range from 1 to 15 parts by mass with respect to 100 parts by mass of a (A) polyamide resin. In the resin composition, the number average particle diameter of the fluorine series resin dispersed in the polyamide resin is 0.8 ?m or less. The resin composition includes particles of the (B) fluorine series resin having particle diameters of 0.8 ?m or greater. The percentage of particles having particle diameters of 0.8 ?m or greater which are secondary particles while maintaining the form of primary particles is 60% or greater, and/or the degree of crystallinity of the dispersed (B) fluorine series resin is 42 J/g or greater.

Abstract: A computer system comprises a computer main body including a main board on which various components such as a CPU and the like are mounted and a hard disc unit; a read-only optical disc drive provided in the computer main body; a write-only optical disc drive which is constructed separately from the read-only optical disc drive, the write-only optical disc drive being provided in the computer main body; and a bus for connecting the main board, the hard disc unit, the read-only optical disc drive, and the write-only disc drive with each other, in which the hard disc unit, the write-only optical disc drive and the read-only optical disc drive are connected by means of a cascade connection.

Abstract: A heat exchanger comprises a plurality of layered units of tube assemblies, each tube assembly unit comprising a tube made by two plates having a refrigerant inlet opening and a refrigerant outlet opening, and a spacer block is disposed between the upper and lower tube assemblies for forming an air passage having an air inlet side and an air outlet side. The refrigerant inlet opening is provided in the lower plate of the tube adjacent the air inlet side. The upper and lower tube assembly units are alternately arranged with respect to the refrigerant inlet and outlet openings. The spacer block has an opening for communicating the refrigerant outlet opening of the lower tube assembly unit with the refrigerant inlet opening of the upper tube assembly unit, such that the refrigerant mainly flows in a portion in the tube adjacent the air inlet side.

Abstract: A new and useful coke oven door which is simple in construction but provides complete sealing efficiency. A pair of supporting holes are formed on each of upper and lower portions of the side plates of the door body, and through the supporting holes a locking bar extends which has on the center portion an arm for rotating and on both ends rollers eccentrically located with respect thereto. By rotating the locking bar with the arm, the door can be moved slightly backward or forward when removing or installating lest the knife edge should scratch the door sealing frame.
