    摘要: There is provided a magnetic recording medium which is well evaluated in a running reliability, has small amount of seizing on a magnetic head, suppresses a wear rate of the magnetic head, and maintains high reproduction power during running of the magnetic tape for a long time. The magnetic recording medium, in tape form, reproduces a magnetic recorded signal by a reproducing magnetic head utilizing a magnetoresistive effect element, and has a nonmagnetic layer including nonmagnetic powder dispersed in a binder, and a magnetic layer including ferromagnetic powder dispersed in a binder, the nonmagnetic layer and the magnetic layer are successively formed on a long tape-like nonmagnetic substrate, wherein the nonmagnetic layer contains the nonmagnetic powder having pH of 7.5 or more, and wherein the nonmagnetic layer or/and the magnetic layer contain at least one fatty acid amide having an alkyl group having 8 or more carbon atoms.

    摘要: In a screen light computation device, a first polarizing filter (93) blocks P waves reflected by a reflective surface, and screen light; the reflected light sensor (95) receives S waves; a second polarizing filter (83) allows the screen light to pass while blocking the S waves; and a screen light sensor (85), being set at Brewster's angle, where the P waves is not received, still receives some leakage P waves. A screen light extraction computation (LUT; not shown) stores a correlation between the detection value by the reflected light sensor 95 and the detection value by the screen light sensor 85. The LUT is queried, a value of only the screen light that does not include reflected light is computed, and the screen light that does not include ambient light (reflected light) reflected in a display screen of the monitor is detected without turning off a backlight of a monitor.

    摘要: Marine propulsion unit having a propeller assembly formed with exhaust gas passages through the propeller hub. An outer pipe is provided to encircle the propeller hub with a radial spacing and has a rear end extending beyond the rear end of the hub so that the exhaust gas is forced to flow, during a reverse movement, from the exhaust gas passage in the hub to the space between the hub and the outer pipe.
