摘要： A drill screw is produced by a pinch pointing die comprising a pair of substantially identical drill point forming portions each of which includes a half conical recess, a half cylindrical recess and a half truncated conical recess. The drill screw thus produced comprises, therefore, substantially identical two half drill point portions each of which includes a half conical portion, a half cylindrical portion and a half truncated conical portion.

摘要： In a sound board assembly for a musical instrument, a plurality of straight-grain wood veneers are joined together in a plane to form a plate unit having front and rear surfaces. Each of the wood veneers has two lateral sides which extend in a direction along the grain of the wood veneer. The lateral sides of the wood veneer serve respectively as a pair of abutments. One of the pair of abutments of one of each pair of adjacent wood veneers is abutted against and joined to one of the pair of abutments of the other wood veneer. A plurality of voids are formed inside of the plate unit. Substantially, the voids are formed along a neutral plane of the plate unit which is in the middle of the two surfaces. Thanks to the voids in the plate unit, the above sound board assembly is capable of sufficiently exhibiting the merit of a woody sound, capable of setting the sound quality artificially and freely, and capable of realizing the woody sound that has more warmth than in the case where high-quality natural woods are used.

摘要： A novel armature of an electric rotating machine is disclosed. The armature core is divided axially into two or more members. The coils of the armature winding are fixed on the armature core in such a way that two or more coil sides are disposed in each slot of one member, and the coil sides disposed in the same slot are arranged in adjacent different slots of the other member. The end of each coil is positioned in a manner to substantially equalize the mutual inductance between each pair of adjacent coil ends.

摘要： The present invention provides a process for producing an aqueous dispersion of a polymer substance, wherein a mill is used as a mixing apparatus, the mill comprises a disk-type rotor serving as a rotational body and a stator serving as a non-rotational body, the rotor and the stator are disposed oppositely, a protrusion is formed on at least one of the opposed surfaces of the rotor and the stator, the rotor and the stator are disposed such that the distance therebetween becomes narrower, a polymer substance serving as a raw material which is melted in advance so as to assume a liquid state and an aqueous poval solution are fed to the narrow space in the mill, and the rotor is rotated at high speed, to thereby produce an aqueous dispersion. The process may provide downsized producing equipment while saving space and reducing equipment cost.
