摘要： An oscillating apparatus comprises a cylinder, a piston reciprocatingly movably fitted in the cylinder, shaft members connected to the piston and extending out of the cylinder. The cylinder, piston and shaft members form an oscillator. An inlet and an outlet for an electro-rheological fluid are provided at each of two cylinder chambers defined in said cylinder by the piston. The apparatus further comprises voltage applying devices for applying electric voltage to the electro-rheological fluid passing through the inlets and outlets, respectively, so that applications of the voltage to the inlet of one cylinder chamber and the outlet of the other cylinder chamber are simultaneously effected and applications of the voltage to the inlets of both the cylinder chambers are alternately effected. With this arrangement, the switching-over of the closing and opening of the inlets and outlets are very rapidly performed by the application and removal of the electric voltage so that the piston undergoes vibration which is transmitted through the shaft members to an object, structure or the like, with the result that the object is controllingly vibrated and vibration to which the object is subjected is effectively damped.

摘要： A noise reducing apparatus in the form of a hollow body comprising two or more passage groups consisting of a plurality of passages. The length of each passage is determined such that the sound waves emitted from the passages of the adjacent passage groups form plane waves which are shifted by a half wavelength so that plane waves interfere each other. The apparatus can be secured to an opening of construction and reduce the level of sound pressure from a sound source without any closed shield construction surrounding the sound source.

摘要： A device for controlling a propagation direction of noise, which is preferably associated with a sound insulating wall to significantly improve its sound reducing effect of alleviating noise emitted from a noise source such as a railroad, highway and the like on which an electric car and automobiles run. The device comprises a hollow structural body composed of a plurality of elongated vertical hollow passages arranged at right angles to a substrate and spaced apart from each other by means of partition walls. The upper noise inlet side surface of the hollow passages face a propagation direction of noise emitted from the noise source and serve to refract and lag in phase the noise passed therethrough, thereby producing a sound reducing region located intermediate between a direct sound propagation and the refracted sound propagation. In one embodiment, a pair of hollow structural bodies are arranged in opposition to each other to form an arch type device. In another embodiment, the hollow structural body may be provided at its noise inlet or outlet side surface with an extension of the hollow passages.
