摘要： PURPOSE:To eliminate micro-vibration from the ground surface by arranging a levitating electromagnet opposed to upper and lower surfaces of a lowermost flange, a gap sensor, magnetic dampers opposed to upper and lower surfaces of the other flange in a fixing body housing a pillar body having flanges in an arranged clearance, and driving the electromagnet and the dampers according to a sensor signal. CONSTITUTION:When vibration is generated, a vertical direction controller 21 detects relative displacement of a distance between an upper surface of an annular groove lid and a flange part 2d according to a signal of a gap sensor 13, and determines a control current to adjust intensity of a magnetic field of a levitating electromagnet 12 according to the displacement, and drives the levitating electromagnet 12, and changes levitating force to an assembly body A, and eliminates vibration from the ground surface G. Horizontal direction controllers 20a-c detect absolute acceleration of the assembly body A according to signals of acceleration sensors 3a-c, and determine a control current to adjust intensity of magnetic fields of magnetic dampers 14a-c according to the acceleration, and drive electromagnets of the magnetic dampers 14a-c, and generate damping force, and prevent rocking.

摘要： PURPOSE:To install actuators easily on the same level in a simple structure by erecting a half mirror so that one surface can be situated on a vertical surface being at an equal distance and an equal angle to a set of electromagnetic actuators, and arranging a reading microscope to find level deviation from images by the transmitted light and reflected light. CONSTITUTION:A reading microscope 8 is installed in a position where transmitted light A from an actuator 1 can be observed. An image (a) by the transmitted light A from the actuator 1 and an image (b) by reflected light B from an actuator 2 are projected in a visual field 9 of the microscope 8. When a level of the actuator 2 is low, a shim equivalent to level deviation E is inserted in the bottom part, and the level is adjusted so that the images (a and b) can coincide with each other. Next, a half mirror 6 is rotated by 135 degrees in a clockwise direction, and is inclined by 45 degrees to the actuator 1 being a reference to the axis X, and the microscope 8 is moved, and a level of an actuator 3 is adjusted similarly to the actuator 1. A level of an actuator 4 is adjusted similarly.

摘要： PROBLEM TO BE SOLVED: To reduce the story height and construction cost by imparting a width lying astride columns parallelly arranged, to a floating slab and using the floating slab as a slab and a beam for the building frame in common. SOLUTION: In this floating slab 2, a precast concrete floor slab used as a form in common is laid between columns 3, 3, and upper end reinforcements and stirrups in thick parts or the like are arranged and concrete is placed so that the floating slab is isolated from the columns 3 and the wall 4 of the building frame. Then the floating slab 2 is mounted on the columns 3, 3 parallelly and breadthwise disposed to transmit the weight of a train to both columns 3, 3 and keep the distance between the columns 3, 3 by connection of the columns and further, serve as a beam. Accordingly, a slab and a beam for the building frame are not required and hence, the slab thickness, the beam height, and the story height can be lessened and the construction cost can be reduced.

摘要： PURPOSE:To attain use as a room accessory or a indoor sensor by inputting an environmental element such as light or heat to a noise monitoring box of simple constitution, and also providing a communication facility. CONSTITUTION:Noise is collected by a microphone having a necessary frequency range and a frequency characteristic approximate to an auditory sense characteristic, and this is amplified by a frequency correcting amplifier by which a noise measuring range can be preset in several stages by an environment. An electric signal in proportion to this sound pressure change is inputted to a level converter, and after it is converted into an effective value by a time constant stipulated in a noise meter standard, a value converted into a logarithm is outputted and displayed. A display unit can also display data on light or heat or the like from an environmental element input device besides displaying a noise level. Information can be sent to a remote place by using a communication facility together for data transfer. Various controls such as turning off electric power supply after constant time operation can be performed by using an electric power controller together while using battery operation as the electric power supply. When a light generator is used together, replacement of a battery can be reduced.

摘要： PURPOSE:To provide a damping device which is constituted to constrain only horizontal vibration and perform vertical vibration and rocking by a method wherein a vertical slide means is attached to an air spring, the upper end thereof is attached to an upper plate through an oscillating means and the lower end thereof is attached to a buffering rubber through a lower plate. CONSTITUTION:An air spring 1 is nipped between upper and lower plates 2 and 3. A stroke ball bearing serving as a vertical slide means is disposed at the inner central part of the air spring l. In this case, a link ball 6 is disposed at the upper end part of the bearing 5a. Further, the upper part of a shaft 5b is inserted in the bearing 5a and the lower part of the shaft 5b is fixed to a lower plate 3. The lower plate 3 is attached to a building floor through a pair of bases 3a and 3b between which a buffering rubber 4 is nipped. This constitution absorbs vertical vibration by means of the air spring 1, smoothes vertical movement by the bearing 5a and absorbs horizontal vibration, performs operation following rocking by means of the link ball 6, and provides a buffering effect by means of the buffering rubber 4.

摘要： PURPOSE:To prevent the generation of a solid propagating sound when a weight swings, and support stably vertical, lateral and longitudinal directional loads acting on a base frame. CONSTITUTION:A weight 5 is loaded on a base frame 3 so as to be capable of swinging freely in the lateral direction. The base frame 3 is installed on a building floor 1 through a vibrationproof material 9. Blocks 10 are arranged protrusively on both left and right surfaces of the base frame 3. Support brackets 11 are arranged fixedly on the floor 1 so as to surround the blocks 10. Vibration-proof materials 12, 13 and 14 are interposed between the upper surfaces of the blocks 10, the projecting end surfaces, the front and rear side surfaces and the support brackets 11. The respective vibration-proof materials 9, 12, 13 and 14 are formed in a structure having a rubber vibration isolator.
