摘要： A piezoelectric buzzer comprising a case having the shape of a bottomed cylinder, a piezoelectric diaphragm fixedly disposed within the case, a cover plate fitted in the open end of the case, and terminals integrally combined with the cover plate and each having one end in contact with the piezoelectric diaphragm and the other end projecting outside from the cover plate. Since the cover plate and the terminals are combined together by insert molding, no gap is formed between the cover plate and the terminals, no sealing work for sealing gaps between the cover plate and the terminals is necessary, the manufacturing process is simplified, and the piezoelectric element is not exposed to the external atmosphere. A method of manufacturing such a piezoelectric buzzer comprises steps of arranging a plurality of metallic strips for forming terminals in parallel to each other, forming notches in one side of each metallic strip at predetermined intervals, simultaneously forming a plurality of cover plates integrally combined with the metallic strips by insert molding, cutting the metallic strips at predetermined positions between the adjacent cover plates, and bending the metallic strips projecting from each cover plate at the notches to form terminals. The metallic strips can be easily bent at the notches to form the terminals after being combined with the cover plates by insert molding without requiring special work for deciding positions where the metallic strips are to be bent.

摘要： An industrial robot and a device for forecasting breakage of cables, which is capable of predicting the time of breakage of cables provided between a control section and arm drive sections in the industrial robot. Sample wires whose life period is shorter than that of the cables are provided to the cables, respectively, and based on the breakage of the sample wires, the breakage of the cables is forecasted to thereby make it possible to replace the cables timely.

摘要： A process and an apparatus for forming aerosols of pesticidal chemicals, said process comprising vaporizing water in a steam generator fitted with a heater, heating the resultant steam to 110.degree.-800.degree. C in a superheating means, passing the superheated steam from the superheating means, while controlling its temperature, to an evaporator containing the pesticidal chemicals and connected to the steam generator through superheater thereby to effect the heating, evaporation and entrainment of the chemicals with steam, releasing the resulting entrained vapor in the air to form aerosols of the pesticidal chemicals. The aerosols are used to control indoor or outdoor fungi, bacteria, viruses, and insects.
