Abstract: A panel-type heating element has a base and a thin film containing zinc oxide and tin oxide formed on the base. The panel-type heating element is manufactured by a method comprising spraying a solution containing a zinc compound and a tin compound which give oxides respectively by heating in a high temperature reaction chamber to form a thin film consisting of sediment containing zinc and tin oxide on the surface of the base. The thin film has excellent acid, water and chemical resistance, and heats quickly.

Abstract: The object of this invention is to provide a panel-type heating element having an excellent durability and high effectiveness in power saving. To attain this object, the present invention provides a panel-type heating element consisting of a base which a thin film containing zinc oxide and tin oxide can form a layer upon. The panel-type heating element is advantageously manufactured by a method comprising spraying a solution containing a zinc compound and a tin compound on a base. The solution then oxidizes by heating the base in a high temperature reaction chamber to form a thin film consisting of sediment containing zinc oxide and tin oxide on the surface of the base. As a result, the thin film gives the base excellent acid, water and chemical resistance, and heats quickly.

Abstract: A water intake portion of a hydraulic machine consists of a casing and a speed ring positioned between the casing and guide vanes for guiding water from the casing to the guide vanes. The speed ring consists of a pair of upper and lower flat members of a ring form, a plurality of stay vanes positioned between the aforesaid pair of members for interconnecting same rigidly, and a reinforcing member of a cylindrical form, which is welded to the top surface of the upper flat member between the inner and outer circumferential edges of the upper flat member. Edges defining therebetween an opening of this casing are welded to the top surface of the upper flat member of a ring form, of the speed ring in the position between the aforesaid reinforcing member and the outer circumferential edge of the upper flat member, as well as to the undersurface of the lower flat member of a ring form, respectively.

Abstract: A method for producing a syrup from which a soft drink containing cow's milk and having stable white turbidity resembling that of cow's milk is produced is disclosed, wherein the syrup is produced by mixing as basal ingredients cow's milk, sugar and an edible acid under a specific condition without use of any stabilizer for the suspension of milk protein.

Abstract: An object disposed in a fluid flow and defined by two surfaces, each extending along a stream line and one of said two surfaces having a reference contour. To eliminate the danger that a violent oscillation is generated due to resonance between the natural oscillation of the object and the oscillation caused by Karman's vortex which develops at the downstream end portion of the object, said downstream end portion of the object is so formed as to provide a configuration satisfying the following relations:R1/TV.ltoreq.0.2 and R2/TV=6-10where, R1 is a radius of curvature of the first portion of object's downstream end portion which is continuous with said reference surface, R2 is a radius of curvature of the second portion of object's downstream end portion extending between said first portion and the other surface, and TV is the minimum thickness of the object between said two surfaces measured from the joining point or juncture between said second portion and the other surface.
