Abstract: The present invention provides an applicator used for applying viscous cosmetics such as lip gloss and viscous pharmaceutical preparations such as ointments, the applicator being sanitary and disposable but capable of reliably scooping the cosmetic or pharmaceutical preparation, coming into firm contact with the application area, and easily spreading the cosmetic or pharmaceutical preparation. Provided is an applicator 1 having a cotton body 3 that extends from an end portion of a shaft 2 and has a flat curved shape in which a maximum width W is 4.5 to 6.5 mm and a thickness T at a thickest portion is 2.0 to 3.6 mm, wherein an imaginary line 4 connecting a tip portion of the cotton body and a rear end central portion thereof has an inclination angle of 25 to 35 degrees with respect to the shaft 2.

Abstract: The three-phase motor driving apparatus according to an aspect of the present invention comprises a controlling part that estimates a rotational position of the three-phase brushless motor based on a reference pulse signal output by the rotor sensor according to a rotational position of the magnetic pole of the first phase of the rotor when the three-phase brushless motor rotates, and controls the motor driver in driving patterns sequentially prescribed so as to correspond to the estimated rotational position of the three-phase brushless motor.

Abstract: Sections 1 and 2 each in the form of a welded pipe (square pipe) are provided. The sections 1 and 2 are brought into abutment with each other so that the respective end faces 3a and 3b abut each other at a predetermined angle .beta. between each section and its axial direction. The sections 1 and 2 are arranged symmetrically with respect to each other. Acute end portions of the abutted portion are chamfered to from a plane part. Corners of the sections 1 and 2 are rounded. In such a combined state of both sections, the abutted portion is welded in the circumferential direction to form a weld bead. As a result, penetration of weld metal to the section 1 and that to the section 2 become equal to each other. Thus, it becomes possible to fabricate a welded structure having a uniform weld bead and having improved strength and reliability of welded portions.

Abstract: A process for the production of yogurt powder possessing an immunological activity, in which yogurt is heated at 60.degree. to 100.degree. C. and it is provided with an alkaline agent to adjust the yogurt to pH 7.0 to 96, and thereafter dried to a powder. Before powdering, the yogurt may be subjected either to the addition of a non-ionic surfactant or to high pressure homogenizing treatment. Yogurt retaining immunological activity can be used effectively as food and feed.
