摘要： PURPOSE:To make the bending-resistant load larger by a structure wherein stiffeners are equipped on the inside or outside surface, except four corners, in the longitudinal direction of duct plates, on the side of which bending load is applied. CONSTITUTION:T-shape stiffeners 10 are equipped by welding or the like on the inside surface of the upper and lower plank surfaces 1 of a duct in the longitudinal direction at its middle part. Due to the above-mentioned structure, the middle part of a duct plate, the part of which has not contributed to the bending strength at a conventional duct, can be made contribute to the bending strength. Consequently, the strength to bending load of the duct can be heightened.

摘要： PURPOSE:To effectively exfoliate dust, by utilizing the remarkable difference produced in a transmission of hammering energy at the time of hammering and in a vibration response of a collecting electrode plate according to a fixing method, in a case of fixing the collecting electrode by clamping the electrode with bottom edge members. CONSTITUTION:A collecting electrode plate 1 is press formed to have a cross section of which continuously arranged trapezoids project alternately in reverse directions. The bottom end of the plate 1 is clamped by a pair of bottom edge members 3, and 2 spots of the trapezoidal projecting-parts of the plate 1 are fixed to the members 3 by bolts and nuts through projecting piece-liners 10 and recessing piece-liners 11. The bottom end part of the plate 1 except the fixed projecting parts is separated from the members 3 to form gaps (g) and (g') by interposing the liners 10 and 11. As the results of said method, the dust is effectively exfoliated by a comparatively small hammering force without using a complex means.

摘要： PURPOSE:To prevent a device easily damaged by vibration from earthquake vibration and environmental vibration, by a method wherein, by mounting a vibration isolating bed on a foundation bed, supported on rolling balls, through lamination rubber structures, vibration during earthquake is absorbed and fine vibration, e.g. environmen tal vibration, are enoughly absorbed. CONSTITUTION:Vibration of micron order, e.g. environmental vibration, is transmitted to a foundation bed 16 through rolling balls 12, 12... and support seats 14, 14.... Fine vibration in a horizontal direction and vertical direction generated to the foundation bed 16 is absorbed by means of lamination rubber structures 32, 32.... Thereby, fine vibration is not transmitted to a vibration isolating bed 34, and a device easily dam aged by vibration on the vibration isolating bed 34 is hardly influenced by fine vibra tion. When earthquake occurs, the rolling balls 12, 12... are rolled on a foundation bed floor 10, and vibration of the foundation bed 16 generated by earthquake is re placed with low frequency through the force of springs 20 and 20. The foundation bed 16 and the vibration isolating bed 34 are widely resonated approximately in an equal phase, slow and high swing is generated on the vibration isolating bed 34, and the vibration is gradually absorbed. Thus, the device easily damaged by vibration on the vibration isolating bed 34 is widely swung in a horizontal direction, but a fear of the device falling down is eliminated.

摘要： PURPOSE:To facilitate dust peeling by fitting a dust collecting plate to a fixture by use of the recessed part and projecting part of the fixture and the deformed part of a dust collecting plate, and thus transmitting impact force effactively. CONSTITUTION:In the fixation structure where a dust collecting plate 30 is clamped between hammer-head beams 22 and 24 through a couple of fixtures 26 and 28, the fixture 26 has a recessed part 40 in the surface facing a dust collecting plate 30. The recessed part 40 is semicircular in a plane containing the axis of a clamping bolt 32, and annular and coaxial with the bolt axis in the axial direction of the bolt 32. In the surface of the fixture 28 facing the dust collecting plate 30, a projecting part 42 corresponding to the recessed part is formed. Then, the projecting part 42, when the fixtures 26 and 28 clamps the dust collecting plate 30, forms a gap as great as the thickness of the dust collecting plate 30 to contain the deformation part 44 of the dust collecting plate 30.

摘要： PURPOSE:To obtain a filter material for a filter capable of purifying contaminated water stably in high reliability, by filling a casing with a diffusion bonded magnetic stainless fiber to increase the strength of the filter material. CONSTITUTION:A casing 20 is filled with a magnetic stainless steel fiber 22 and, after said fiber is degreased with trichloroethylene, it is subjected to intermetallic diffusion bonding in a vacuum heating furnace and thereafter cooled rapidly. Thus obtained filter material is free from the outflow of a metal fiber piece even if filtration and backwashing are repeated compared to a filter material with a conventional structure because of intermetallic diffusion bond and the lowering of filtering capacity.

摘要： PURPOSE: To prevent a pulverulent material from colliding against a casing and blade in a rotary valve conveying fixed quantity of the pulverulent material, by guiding a leak of air in an end side of the blade from a rotary directional front side partitioning chamber to its inside direction.
CONSTITUTION: A guide flow line 11 of leaked air is formed in a front side partitioning chamber 8 in the rotary direction of a blade 7. Said guide flow line 11 is formed by a gap between a baffle plate 12 and well surface 7A, and a leaked air stream 9, containing a pulverulent material 3 passing through a gap between internal peripheral surfaces and the blade, is decelerated by a baffle plate 12 and guided as a laminar flow to the internal direction of the partitioning chamber 8. Accordingly, movement of the pulverulent material 3 caused by a swirl is suppressed, and collision of the pulverulent material 3 against a casing 1 and the blade 7 due to intrusion of the leaked air can be avoided, then the wall surface can be prevented from wearing.

摘要： PURPOSE:To sufficiently absorb earthquake vibration or environmental vibration, generated in a vibro-isolating quake-isolating bed, by constituting a device alternately piling up an elastic material and a magnetic material and arranging the adjacent fellow magnetic materials so as to attract each other by magnetic force interposing the elastic material. CONSTITUTION:Vibration absorbing units 12 are mounted to a predetermined position on a foundation floor 10. The vibration absorbing unit 12, alternately piling up a rubber plate 14 and a magnetic plate 16, is formed into a column shape. The fellow adjacent magnetic plates 16 are arranged in such a manner as to attract each other by magnetic force interposing the rubber plate 14 in a sandwich state as shown by an arrow head A. In this way, earthquake vibration or environmental vibration, generated in vibro-isolating and earthquake- isolating beds, can be sufficiently absorbed.
