Abstract: A main object thereof is to provide a non-oriented electrical steel sheet being excellent in surface characteristics and having both excellent mechanical characteristics and magnetic characteristics necessary for a rotor of rotating machines such as motors and generators which rotate at a high speed, and a method for producing the same. To achieve the object, the present invention provides a non-oriented electrical steel sheet comprising in % by mass: 0.06% or less of C; 3.5% or less of Si; from 0.05% or more to 3.0% or less of Mn; 2.5% or less of Al; 0.30% or less of P; 0.04% or less of S; 0.02% or less of N; at least one element selected from the group consisting of Nb, Ti, Zr and V in the predetermined range; and a balance consisting of Fe and impurities; and having a recrystallized fraction being less than 90%.

Abstract: A drain bolt mounting structure comprises a bottomed hole formed on an outer surface of an oil pan to extend continuously with a drain hole of the oil pan, a female thread formed on an inner peripheral surface of the drain hole; a drain bolt including a shaft portion having a male thread threadingly engageable with the female thread of the drain hole and a head portion formed at one end portion of the shaft portion; a press-in member formed of a second metal containing aluminum which has a higher standard electrode potential than a first metal forming the oil pan, the press-in member being configured to be pressed into the bottomed hole; and a crushing member configured to be crushed between the press-in member and the head portion of the drain bolt.

Abstract: This invention provides an electrode for a fuel cell comprising a catalyst layer obtained by a first step of homogeneously mixing carbon supporting platinum which is an electrode catalyst, an alcohol solution of an ion conductive component which is a solid polymer electrolytic membrane component, and an organic solvent, by means of a stirrer having a grinding effect to produce electrode paste in which the carbon is highly dispersed; a second step of stirring said electrode paste by means of a three-dimensional vibrating stirrer in order to obtain highly structured carbon on which platinum is supported; and a third step of coating a gas diffusion electrode material and/or a solid polymer electrolytic membrane with the electrode paste in which the carbon is highly structured, followed by removal of the organic solvent.

Abstract: A method of obtaining an excellent recycled pulp from waste pressure-sensitive adhesive paper which has previously been discarded. This method being characterized in that the waste paper is defiberized, then a defiberized suspension thereof is diluted, the diluted suspension is coarse screened by a screen having a slit width of below 0.5 mm, the pulp suspension after coarse screening is dewatered so as to have a solid matter consistency of 15 to 40% by weight, the dewatered stuff is mechanically agitated, the difference between the temperature of the stuff before the agitation and the temperature thereof after the agitation being below 12.degree. C., the obtained stuff is being diluted again, the diluted suspension is fine screened by a screen having a slit width of below 0.
