    摘要： In a power transmission system comprising at least two trolley wires for supplying an alternating current power to an electric vehicle, and at least two feeder lines coupled to the trolley wires at feeding points of the corresponding trolley wires spaced apart a given interval for feeding a voltage to the trolley wires, with a closed loop formed between a portion of the trolley wires and a portion of the feeder lines through two adjacent feeding points, a throughtype current transformer is provided for each feeder line such that the feeder line extends through the transformer and the primary winding of the transformer is connected to receive an alternating current voltage between the above described at least two trolley wires, whereby a secondary alternating current induced in the feeder lines serving as a secondary conductor of the transformer flows through the above described closed loop, which causes a Joule heat along the trolley wires, thereby to deicing of the trolley wires. Preferably, an alternating voltage between the above described at least two trolley wires is selectively applied to the primary winding of the transformer, such that a supply of the alternating current voltage to the primary winding is controlled manually or automatically responsive to meteorological conditions. Such an automatic control of a supply to the primary winding of the transformer may be selectively effected, in association with the temperature of the trolley wires being lower than a preset temperature, a predetermined meteorological condition being met by an ambient temperature, water, snow and the like, a current normally flowing through the trolley wires being less than a predetermined value, and the like, singly or in combination.

    摘要： In order to provide a magnetic recording medium having excellent electromagnetic conversion characteristics, a magnetic recording medium (10) is provided with a substrate (12), and a magnetic recording layer (20) formed on the substrate (12). The magnetic recording layer (20) is provided with a granular layer (32), i.e., a magnetic layer, including magnetic grains and a nonmagnetic material surrounding the magnetic grains in a section parallel to the main surface of the substrate. The ratio of the long diameter to the short diameter of each magnetic grain contained in the granular layer (32) is calculated in the section. In the histogram of such ratio, a half width at half maximum of the histogram is 0.6 or less and the variance of grain diameters of the magnetic grains in the section is 20% or less of the average grain diameter of the magnetic grains.

    摘要： An object of the present invention is to improve a phenomenon of the life-shortening of the endurance life due to scratch occurring when recesses of a fixed dimple shape are formed on the surface of the surface layer, in order to inhibit the chattering and folding back of a cleaning blade and the fracture of an edge, which occurs because friction between the surface layer of the surface of an electrophotographic photosensitive member and an abutting member is high; and particularly to improve the above described problems, from initial printing through printing on many sheets, which become particularly remarkable when using an electrophotographic photosensitive member with the use of a curable resin that is improved so as to have a high elastic deformation rate for the surface layer, in order to improve the strength of the surface layer, for the purpose of increasing the durability of an electrophotographic photosensitive member. An electrophotographic photosensitive member for achieving the object, which has a support and an organic photosensitive layer, is characterized in that the electrophotographic photosensitive member has dimple-shaped concavities formed on the surface of the surface layer of the electrophotographic photosensitive member, and further has the recesses with the same pattern as that on the surface of the surface layer, formed on the interface created between the surface layer of the organic photosensitive member and the layer directly under the surface layer (a subsurface layer).
