In an extrafine or ultrafine copper alloy wire having an outer diameter of not more than 0.1 mm, the copper alloy wire is formed of a heat treated copper alloy comprising 0.05 to 0.9% by weight in total of at least one metallic element selected from the group consisting of tin, indium, silver, antimony, magnesium, aluminum, and boron and not more than 50 ppm of oxygen with the balance consisting of copper. By virtue of this constitution, the extrafine or ultrafine copper alloy wire has a combination of excellent bending fatigue lifetime based on high tensile strength and excellent torsional strength based on high elongation or a combination of excellent tensile strength, electrical conductivity, and drawability and good elongation. The invention has been described in detail with particular reference to preferred embodiments, but it will be understood that variations and modifications can be effected within the scope of the invention as set forth in the appended claims.

A sheet feeding apparatus capable of obtaining a sufficient conveying force for pulling back double-fed overlapping sheets to a stacking tray side. A sheet feeding member feeds sheets incoming from a stacking tray which stacks the sheets into a conveying pass. A separating member separates the sheets fed to the conveying pass by the sheet feeding member one by one. A double feed detection sensor generates an output for detecting double feed of sheets fed to the conveying pass. A rotatable member contacts the fed sheet. A driving unit rotationally drives at least the rotatable member in a rotational direction for reverse feeding of sheets. A control unit controls the driving unit when the double feed of sheets is detected based on the output of the double feed detection sensor, such that the rotatable member is rotationally driven in the rotational direction for reverse feeding of sheets.

A flat cable includes a plurality of wires arranged in parallel, and a fibrous member woven into the plurality of wires in the arrangement direction of the plurality of wires. The fibrous member includes a polyurethane elastic fiber, and has an elongation of not less than 500% and not more than 900%, an elongation recovery rate of not less than 90% at a 300% elongation and an initial modulus of 5 to 30 cN/dtex for the 300% elongation.

A flat cable includes plurality of electric wires juxtaposed with each other and a fiber member woven along a juxtapositional direction of the electric wires to thread through a plurality of the electric wires. Each of the electric wires includes an outermost layer having a layer with an elongation of 20% or more and 100% or less and a tensile strength of 150 MPa or more. The fiber member is a fiber mainly made of polytrimethylene terephthalate.
摘要:
A sheet feeding apparatus has a pair of feeding roller and separating roller an inter-shaft distance changing mechanism for the pair of rollers, and sheet detecting means, and a sheet fed is rammed against the surface on which the feeding roller and the separating roller overlap each other to thereby correct skew feeding, and the feeding roller and the separating roller are moved away from each other to thereby feed the sheet. When the passage of the fed sheet between the feeding roller and the separating roller is detected the feeding roller and the separating roller assume a state in which sheet feeding is impossible. By the above-described operation being performed for each sheet, the correction of skew feeding and the separation of a sheet are effected by the feeding roller and the separating roller.
摘要:
As much tag information as corresponds to the number of blocks stored in main memories is stored in tag memories. The tag information indicates whether or not a processor belonging to a node other than the nodes containing tag memories has made an access request and the contents of a cache have been rewritten. Bus bridges perform cache coherency control, referring to the tag information. When the tag information indicates "Modified," the bus bridges stop the data read from the main memories and send the correct data to the requesting processor after a copy-back process of the modified block has been completed.
