摘要： A vibration damping apparatus for transportation includes a vertical direction damping device having air springs and air dampers arranged in parallel on a base and horizontal direction damping device having laminated rubbers. The vertical and horizontal damping devices are combined in series for supporting a load base. The apparatus further includes an air supply source for supplying air into the air springs, control valves provided between the air springs and the air supply source for controlling air supply into and exhaust from the air springs, displacement detecting device for detecting displacements of the load base relative to the bases, and control device for controlling the control valves on the basis of results detected by the displacement detecting device to maintain the load base horizontally and at a constant level relative to the base whatever load is loaded on the load base.

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 vibration control system for damping vibration of an body to be isolated against vibration. The body is supported on a movable base through the medium of vibration-damping supporting structure. The control system comprises a vibration sensor for detecting vibration of the movable base. An inverse vibration signal generating circuit includes a digital sensor and in supplied with a detection signal outputted from the vibration sensor for generating a signal with a waveform to cancel out the vibration of the body through interference therewith. An actuator is connected operatively to the movable base and the inverse vibration signal generating circuit for converting the signal derived from the latter into a mechanical vibration to be applied to the body.

摘要： A noise control device which produces behind it an enlarged sound reducing region is disclosed. The device comprises a hollow structural body composed of a plurality of elongate hollow passages which are different in length and constructed such that the passage length is made the longest at a substantially center part in a vertical direction and is made gradually shorter from the center part toward upper and lower edges of the hollow structural body. The upper and lower edges allow direct propagation sound emitted from a noise source to pass thereover and therethrough.

摘要： A sound insulating apparatus. Heretofore, the sound insulating apparatus to be installed in a ventilator, etc. of an architecture requires a long duct, and becomes large in its size and heavy in its weight, and is not sufficient in its sound absorbing performance.The sound insulating apparatus according to the present invention comprises a closed container including a first opening and a second opening, and having a sound absorbing member at its internal surface. The first opening is provided with a sound converging means for converging a sound wave coming into the closed container through the first opening to a predetermined place within the closed container. The second opening is formed in a place away from the predetermined place.This sound insulating apparatus is installed in a communicating port for intercommunicating two spaces partitioned with respect to each other, such as, for example, a ventilator of an architecture, with the first opening facing toward one space and the second opening facing toward the other space.
