Abstract: A method for manufacturing a sputtering target with which an oxide semiconductor film with a small amount of defects can be formed is provided. Alternatively, an oxide semiconductor film with a small amount of defects is formed. A method for manufacturing a sputtering target is provided, which includes the steps of: forming a polycrystalline In-M-Zn oxide (M represents a metal chosen among aluminum, titanium, gallium, yttrium, zirconium, lanthanum, cesium, neodymium, and hafnium) powder by mixing, sintering, and grinding indium oxide, an oxide of the metal, and zinc oxide; forming a mixture by mixing the polycrystalline In-M-Zn oxide powder and a zinc oxide powder; forming a compact by compacting the mixture; and sintering the compact.

Abstract: A mobile station includes a parameter retrieval unit that retrieves information representing carrier frequencies of a serving cell and a neighboring cell from a radio base station, a frequency band setting unit that sets a frequency band for measuring radio quality of the serving cell and the neighboring cell, based on the information representing the carrier frequencies of the serving cell and the neighboring cell, and a measurement unit that measures the radio quality of the serving cell and the neighboring cell, based on the set frequency band.

Abstract: An optical fiber feeding mechanism of a scrap collector includes a lower roller and an upper roller for advancing an optical fiber scrap cut out by an optical fiber cutter into a scrap receptacle, and further includes a roller holding member. In a state in which the lower roller and the upper roller are not actuated, the roller holding member forms a clearance enough to keep the lower roller and the upper roller from holding an optical fiber therebetween. After the optical fiber cutter cuts the optical fiber, the roller holding member lowers the upper roller toward the lower roller in accordance with the rotation of the upper roller so that the optical fiber may be held by and between the lower roller and the upper roller.

Abstract: A brake disc rotor which includes sliding plates on the inside and outside which are in parallel with and separated from each other in the axial direction of an axle; a plurality of inner and outer partition walls radially arranged between the sliding plates; a plurality of passages radially formed between the inner and outer partition walls; a plurality of inlet and outlet openings for communicating the passages; and a plurality of connecting openings for communicating the mutually adjacent passages. The stream flowing from the inlet opening is formed along an upper wall of the inner partition walls and the stream is formed in a flow separation portion in the vicinity of a lower wall of the outer partition wall through the connecting openings.

Abstract: In a disc brake assembly including a caliper member mounted on a vehicle body structure in such a manner as to straddle a portion of a rotary brake disc secured for a road wheel, a friction pad supported on the caliper member by means of a pair of hanger pins to be moved toward and away from one side surface of the brake disc for engagement therewith and disengagement therefrom, the friction pad having a backing plate secured thereto to be engaged at one side end face thereof with a torque receiving portion of the caliper member in braking operation and a fluid actuator mounted within the caliper member to press the friction pad against the one side surface of the brake disc, a side projection is provided on at least an upper or lower portion of the one side end face of the backing plate for engagement with the torque receiving portion of the caliper member or on at least an upper or lower portion of the torque receiving portion of the caliper member for engagement with the one side face of said backing plate

Abstract: A brake disc rotor comprising: sliding plates on the inside and outside in parallel with and separated from each other in the axial direction of an axle; fins composed of a plurality of curved long partition walls provided between the sliding plates, radially extending from the internal portion to the external portion, and inclined with respect to the radial direction, and a plurality of curved short partition walls provided in parallel between the mutually adjacent long partition walls and extending from a large-diameter internal portion to the external portion; a plurality of ventilation holes radially divided by the fins and composed of the upper and lower ventilation holes with the short partition walls; and inlet and outlet openings opened inward and outward in the radial direction thereof.

Abstract: The piston of a brake control valve assembly is balanced, during normal front hydraulic system operations, at a predetermined position to allow pressurized brake fluid from a rear master cylinder to flow into a rear wheel cylinder from between a head flange and a seal valve with a predetermined pressure. When the braking operation is sought during trouble or failure in the front hydraulic system, the piston loses its regulated balance and moves, together with a piston sleeve and the seal valve so that the effective area for receiving brake fluid pressure from a rear master cylinder becomes greater than that of the rear wheel cylinder thereby to increase brake fluid pressure transmitted to the rear wheel cylinder. The present invention features particularly the improvement, or reversewise utilization, of the conventional proportioning valve mechanism to permit a very rational brake fluid pressure boosting operation.
