    摘要: In a switching regulator, when a control switching signal received from outside is indicating PWM control, a second reference voltage generating circuit outputs, as a second reference voltage, a voltage that is lower than the minimum voltage of an output voltage range of an error amplifying circuit, so that output signals from a comparator are fixed at a high level. When a control switching signal received from outside is indicating VFM control, the second reference voltage generating circuit adjusts the second reference voltage according to the voltage difference between an input voltage and an output voltage, because the optimum second reference voltage varies according to the voltage difference between the input voltage and the output voltage.

    摘要: A racket string 10 of the present invention includes a synthetic fiber. The cross section is flattened by heating, compressing, and deforming the string after it has been formed, and an indentation is made in any part of the string. The flattened string is wound in a substantially non-twisted state. A method for producing the racket string includes heating the string at a temperature of Tg (° C.) or more and Tm −10 (° C.) or less, where Tg (° C.) represents a glass transition point and Tm (° C.) represents a melting point of a main synthetic fiber constituting the string, compressing and deforming the string between rollers 7a and 7b that are arranged with a predetermined clearance therebetween; and then cooling and winding up the string. In a racket strung with the racket string of the present invention, a principal surface of a hitting surface of the racket is formed of the flat surfaces of the string, and the strings include uneven portions due to torsion that are present partially and non-uniformly on the hitting surface of the racket. Thus, the present invention provides a racket string that can make full use of the features of the flat surface, a method for producing the racket string, and a racket strung with the racket string.

    摘要: This invention is intended to make a crucible feeder mechanism simple in configuration, to realize low cost and to increase the number of accommodated crucibles while making the crucible feeder mechanism small in size. In the crucible feeder mechanism, the crucibles are mounted on an inclined mount surface 311 in parallel and a tapered guide surface guides 312b the crucibles sliding down the mount surface 311 to a crucible moving mechanism 313 provided at an outlet port of a guide member. This crucible moving mechanism includes an accommodation concave portion 3131X accommodating one of the crucibles and provided on a circumferential surface portion 3131a of the crucible moving mechanism. The crucible moving mechanism rotates and moves between an accommodation position at which the accommodation concave portion receives the sliding-down crucible and a feed position at which the accommodation concave portion communicates with a crucible feed port 314 and drops the sliding-down crucible.
