At least one of the components of a rolling member used in a manner in which it is rolled or slid with a mated member is made of carbon steel containing 0.8%-0.9% by weight of C, 0.1%-0.7% by weight of Si, 0.5%-1.1% by weight of Mn, and 0.1%-0.6% by weight of Cr and Fe substantially in the remaining part, wherein an ideal critical diameter DI value calculated from the compositions is 1.5-4.0, and the retained austenite amount after hardened heat treatment is 8%-22% by volume. The value DI is determined by the following equation:DI=(0.311.times.C %.sup.0.498).times.(0.7.times.Si %+1).times.(3.33.times.Mn %+1).times.(2.16.times.Cr %+1)

The purpose of the present invention is to improve the performance properties of the cable terminal end assembly and to make its configuration compact. A cable having signal wires and a ground wire are arranged laterally in a casing which is provided with a coupling section for coupling to the electrical device. The signal wires and the ground wires are separated by an insulation plate, and extend out from the ends of the cable into the casing. Signal wires and ground wires are bonded, to specific respective contact strips disposed inside the coupling section. The electrical connections inside the casing are molded with molding. The advantage of the assembly configuration is that the cables are arranged laterally to house many cables compactly in the casing, and the insulation plate eliminates any possibility of shorting between the signal and ground wires, and signal distribution to the device is made possible, without the necessity for such costly parts as a printed circuit board, by customized selection of the contact strips to be joined to the signal wires and to the ground wires in accordance with the requirements of the device.

A sheet feeder includes a delivery roller that contacts a sheet on a sheet supply tray to deliver the sheet; a first detection sensor disposed upstream of the delivery roller so as to detect the sheet on the sheet supply tray; and a second detection sensor disposed downstream of the delivery roller so as to detect a leading end portion of the sheet on the sheet supply tray. The delivery roller is activated in a state where the first detection sensor detects the sheet on the sheet supply tray while the second detection sensor does not detect the leading end portion of the sheet on the sheet supply tray. Thus, all the actually feedable sheets placed on the sheet supply tray can be fed, thereby reducing a sheet setting failure on the sheet supply tray, which reduces trouble of performing a re-set operation.

[Problem]To provide a method for detecting early-stage lung cancer, which reduce a burden on a subject and are excellent in specificity and sensitivity. [Solution]A lung cancer marker comprising a complement C3dg molecule. A method for analyzing a lung cancer marker comprising the steps of: measuring a level of a complement C3dg molecule as a lung cancer marker in a biological sample to acquire a measured level of the complement C3dg molecule; and making an evaluation as to whether the measured level is high or low based on a reference level of the complement C3dg molecule. Preferably, the measured level of the complement C3dg molecule is a value relative to a measured level of a complement C3 full-length molecule in the biological sample, and herein the reference level of the complement C3dg molecule is a value relative to a reference level of the complement C3 full-length molecule.

According to one embodiment, a magnetoresistive element includes an electrode layer, a first magnetic layer, a second magnetic layer and a nonmagnetic layer. The electrode layer includes a metal layer including at least one of Mo, Nb, and W. The first magnetic layer is disposed on the metal layer to be in contact with the metal layer and has a magnetization easy axis in a direction perpendicular to a film plane and is variable in magnetization direction. The second magnetic layer is disposed on the first magnetic layer and has a magnetization easy axis in the direction perpendicular to the film plane and is invariable in magnetization direction. The nonmagnetic layer is provided between the first and second magnetic layers. The magnetization direction of the first magnetic layer is varied by a current that runs through the first magnetic layer, the nonmagnetic layer, and the second magnetic layer.
