摘要： A magnetic recording medium that uses, as a protective coating layer provided on a magnetic layer for magnetically recording signals, a layer made of a nonmagnetic material consisting of two ore more elements of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, and W, and one or more elements of N, C, O, and B, or made of a magnetic material consisting of one or more elements of Co, Fe, Ni, and Gd, one or more elements of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, and W, and one or more elements of N, C, O, B, and Si is excellent in sliding endurance. When the protective coating layer is made of the nonmagnetic material, the magnetic recording medium is also excellent in corrosion resistance, and when the protective coating layer is made of the magnetic material, the spacing between a magnetic head and the magnetic recording medium can advantageously be made large. Both the cases are high in reliability, and suitable for high density magnetic recording. The magnetic recording medium can be used in combination with a magnetic head that uses a metal magnetic alloy as at least part of the magnetic core to provide an excellent magnetic storage.

摘要： A telescopically extendable hanging mechanism for suspending a lighting device has a driving mechanism provided with wires for controlling extension of the hanging mechanism. A wire take-up means for winding up or unwinding the wires is adapted for telescopically extending out or contracting the hanging mechanism. The wire take-up means is given a rotative force and consists of three discs of which the outermost disc has a recess at its outer edge. A ratchet wheel is provided in the wire take-up means and a sensor lever is provided swingably above the wire take-up means and is always pressed in the direction of the take-up means. The sensor lever is provided with pawls so arranged that they are engaged with the ratchet wheel when the sensor lever is swung toward the take-up means. A pulley is rotatably mounted at an end of the sensor lever and is adapted to receive the wires used for telescopically extending out or contracting the hanging mechanism. A limit switch is designed to detect any swinging motion of the sensor lever in the direction away from the take-up means to cut off the rotative force. A slider provided slidably on a diametrical portion of the outermost disc of said take-up means has its one end projected into the take-up means while the other end terminates in a sector portion positioned in the recess of the take-up means.
摘要翻译：用于悬挂照明装置的可伸缩悬挂机构具有设置有用于控制悬挂机构的延伸的导线的驱动机构。用于卷绕或退绕电线的拉丝装置适于伸缩地伸出或收缩悬挂机构。线材卷绕装置被赋予旋转力并且由三个盘组成，其中最外盘在其外边缘具有凹部。棘轮设置在拉丝装置中，并且传感器杆可摆动地设置在拉丝装置的上方，并且始终沿着卷取装置的方向被按压。传感器杆设置有棘爪，其布置成当传感器杆朝向卷取装置摆动时它们与棘轮接合。滑轮可旋转地安装在传感器杆的端部，并且适于接收用于伸缩伸出或收缩悬挂机构的电线。限位开关设计成可以在远离卷取装置的方向上检测传感器杆的任何摆动，以切断旋转力。可滑动地设置在所述卷取装置的最外盘的直径部分上的滑块的一端突出到卷取装置中，而另一端终止于位于卷取装置的凹槽中的扇形部分。
