Abstract: A dielectric filter is adapted to show a specified coupling capacitance without inadvertently affecting the resonance frequency, in which a dielectric ceramic block is provided with two or more than two resonant conductors arranged in parallel, a conductive circuit film is formed on the open-circuit end surface of said dielectric ceramic block and electrically separated from the inner conductive films of the resonant conductors by arranging insulation gaps therebetween to capacitively couple the conductive circuit film and the resonant conductors by way of the insulation gap.

Abstract: A dielectric filter for a high frequency band includes a plurality of resonators formed by boring a plurality of through holes between the oppositely disposed end surfaces of a dielectric block in parallel with each other and arranging internal conductors on the inner peripheral surfaces of the respective through holes and an external conductor formed on a substantial portion of the outer peripheral surface of the dielectric block. A non-conductive region is formed on the short-circuit end surface and extends in parallel with the direction connecting the resonators, thereby the filter can be controlled satisfactorily for coupling the dielectric coaxial resonators and have a reduced height.

Abstract: An oscillating trough for shotblasting, which prevents workpieces (W) from being damaged when they are turned over in the trough, is provided. The trough includes a depression (24) defined by two surfaces X.sub.4, X.sub.5 extending from the bottom (21) of the transfer portion upwardly and outwardly thereby making an inner angle of 80.degree.-100.degree. and an arcuate surface S connected to the top of each surface X.sub.4, X.sub.5 of the depression. The surface S is an arc in cross section of a radius of 70-100% of the radius of the largest cylinder inscribable in imaginary planes Y and Z each of a predetermined length in cross section, the plane Y at one end intersecting an upper end of the surface X.sub.4 or X.sub.5 with an external angle of 140.degree.-160.degree., and the plane Z at one end intersecting the plane Y with an inner angle of 120.degree.-140.degree..

Abstract: A sugar-coated article having palatinose used as a coating material for a sugar-coating layer of the sugar-coated article, whereby the article having an extremely soft initial biting mouth-feel is formed. A content of palatinose in the coating material in the sugar-coating layer is 25 to 100%.

Abstract: A chewing gum for preventing pyorrhea alveolaris contains 0.2 to 3.0% of lysozyme of egg white and 0.05 to 0.5% of mace extract.

Abstract: A bubble gum having strengthened membrane forming properties wherein the base contains vinyl acetate resin filler emulsifiers, flavor color and fragrance and includes 2.5% to 15% by weight of a fat or oil ingredient, not less than 15% by weight of rubber and 15 to 17 parts by weight wax, said base being free of ester gum.

Abstract: A frozen dessert such as ice cream or ices with chewing gum supporting the frozen dessert is provided. The stick chewing gum is prepared using anhydrous glucose as a sweetener without use of sucrose and subjected to two separate aging steps, especially to a second aging at -10.degree. to -5.degree. C.

Abstract: A single step process for preparation of chewing gum is disclosed wherein all materials comprising gum base materials including natural resin, vinyl acetate resin, polyisobutylene, ester gum, emulsifier, filler and others on one hand, as well as chewing gum additives including sucrose, glucose, starch hydrolysate, artificial sweetener, flavor, colorant and others on the other hand were charged into a single apparatus and kneaded simultaneously in a single step.As the kneading apparatus, and intensive mixer, a Banbury mixer or a pressure type kneader may be employed.

Abstract: A chewing gum base consisting of about 18 to 40% by weight of rubber and about 82 to 60% by weight of basic materials of a chewing gum and a combination of this chewing gum base with ordinary chewing gum additives and fatty matter.
