    摘要: A non-heat treated seamless steel pipe comprising, by weight, C: 0.10 to 0.25%, Si: 0.05 to 1.00%, Mn: 0.50 to 2.50%, P: not more than 0.03%, S: not more than 0.05%, Cr: 0.40 to 1.50%, Mo: 0.05 to 1.50%, V: 0.02 to 0.30%, Al: 0.003 to 0.10%, B: 0.0003 to 0.01%, and N: 0.001 to 0.02%, in which the balance comprises Fe and impurities. According to this non-heat treated seamless steel pipe, a ferrite area ratio is not more than 10%, and a carbon equivalent Ceq. (%) defined by the following equation is 0.45 to 0.85%. Ceq.=C+Mn/6+(Cr+Mo+V)/5+(Cu+Ni)/15

    摘要: A knock sensor employs a piezoelectric element and includes a ring-shaped weight which has a chamfered surface portion formed at an inner peripheral edge of the weight. The knock sensor basically comprises a housing which includes a disc-shaped flange portion and a cylinder portion covered with an insulating tube. A lower lead plate, the piezoelectric element, an upper lead plate, an insulating sheet, a weight, a disc spring, and a nut are stacked on the flange portion and disposed around the cylinder portion in the order of mention. The nut is tightly screwed to the external thread portion of the cylinder portion to fixedly sandwich the stacked parts with the flange portion of the housing.

    摘要: A non-volatile memory provides a signal hold circuit which uses a FAMOS instead of an input transistor of a ratiod inverting amplifier and outputs a change in a threshold value of the FAMOS, for the purpose of reducing the number of elements of the signal hold circuit. FAMOSs for programming and latching are provided respectively, and the FAMOSs are interconnected to each other at their floating gate electrodes to isolate the signal hold circuit and a program circuit and hence prevent a DC current path from being formed between those two circuits, for the purpose of miniaturization of a memory cell.

    摘要: A heat roller fixing device for use in an electrophotographic copying apparatus and the like, which includes a heating roller constituted by laminating a fluorine resin layer on an electrically conductive core member through a primer layer and driven for rotation, and a pressure roller constituted by forming an electrically insulative layer on another electrically conductive core member and held in contact with the heating roller for simultaneous rotation with the heating roller so as to fix a positively charged toner image formed on copy paper onto the copy paper by causing the copy paper to pass between the heating roller and the pressure roller. The primer layer is composed of an offset prevention agent containing carbon black by a predetermined amount, preferably 0.4 to 3.0% by weight.
