    摘要: A vacuum type sewage collecting system, for collecting sewage from a plurality of houses or the like, stores sewage in a sewage reservoir and then delivers the sewage to a sewage treatment station through a vacuum valve and a vacuum sewage pipe. A controller is provided for properly controlling opening/closing operations of the vacuum valve. The controller includes a first vacuum chamber connected to the vacuum sewage pipe via a fluid flow resisting device, a second vacuum chamber likewise connected to the vacuum sewage pipe, an atmospheric pressure introducing unit for introducing an atmospheric pressure into the first vacuum chamber when a detected quantity of sewage stored in the sewage reservoir exceeds a predetermined value, and a shifting unit for selectively introducing negative pressure to the vacuum valve to open or close the latter depending on the present differential pressure between the first vacuum chamber and the second vacuum chamber. A first opening/closing valve is disposed in a parallel relationship relative to the fluid flow resisting device such that the first opening/closing valve is closed when the negative pressure in the vacuum sewage pipe is lower than a preset value. Alternatively, a closed type air tank is connected to the first vacuum chamber via a second opening/closing valve such that the second opening/closing valve is opened when the negative pressure in the vacuum sewage pipe is lower than the preset value.

    摘要: A vacuum-type sewage collecting apparatus collect sewage discharged from a plurality of houses or facilities in an accumulating tank through a vacuum sewage pipe network, the inner pressure of which is negative. The vacuum sewage pipe network includes a plurality of upper stream pipes and lower stream pipes fastened to each other in a branch-like fashion. Each lower stream pipe has a sawtooth-like shape formed by alternately disposed downwardly-sloping portions extending gently downwards toward said accumulating tank, and lift portions fastened to the lowermost portion of a respective downwardly-sloping portion and extending upwardly with a steep slope. The upper stream pipe is connected to the lower stream pipe in a range in which a horizontal plane, which extends through an upper end portion of the lower stream pipe at the position in which the downwardly-sloping portion adjoins the lift portion, is higher than the center of the lower stream pipe. The upper stream pipe opens to the lower stream pipe at a position diagonally above the center of the lower stream pipe as viewed in a plane perpendicular to the pipe central axis. At least a portion of the opening is higher than the horizontal plane, and the upper stream pipe extends from the lower stream pipe diagonally upwards.

    摘要: An optical encoder comprising a photointerruptor having light-emitting and light-receiving optical fibers and a rotatable pulse scale disposed in an optical path between both of the opposed end faces of the optical fibers so as to shut the optical path intermittently, thereby generating optical pulses in accordance with an angle of rotation of the pulse scale, in which the light-receiving optical fiber has a larger diameter and a greater numerical aperture NA than those of the light-emitting fiber. The light-emitting optical fiber may be replaced with a light-emitting device. Further, a reflector may be interposed in the optical path. Optical pulse signals indicative of an angle of rotation can be detected effectively and it is possible to facilitate the assembling or wiring operation and reduce the production cost.

    摘要: A continuous mixer includes a barrel with a hollow interior, and a pair of mixing rotors housed in the barrel and that rotate in mutually different directions, each mixing rotor including a mixing portion with plural mixing flights formed about an axial center of the mixing rotor and projecting radially outward. The mixing rotors have a center distance therebetween smaller than a rotation outer diameter of each of the respective mixing flights. An inter-rotor clearance, which is the smallest clearance between the mixing portions at each rotation phase of the mixing rotors in a cross section perpendicular to axial directions of the both mixing rotors, has a dimension allowing an extensional flow to be generated in a material passing through the inter-rotor clearance. The continuous mixer can reliably and efficiently mix a material having a large viscosity difference between a dispersed phase and a matrix phase.

    摘要: The device for adjusting the degree of mixing according to the present invention is installed in mixing equipment equipped with a kneading/mixing screw for mixing material while feeding the material to a downstream side, wherein a gate member is moved relative to a portion of a circular section provided for the kneading/mixing screw so as to cause a change in the area of a flow path formed between the gate member and the portion of a circular section, thereby adjusting the degree of mixing of the material. Drive quantity changing means is disposed between the gate member and drive means. The drive quantity changing means is constructed so as to change the drive quantity, x, into the movement quantity, Δδ, in accordance with a profile such that a change rate of the movement quantity, Δδ, relative to the drive quantity, x, is made smaller when the degree of opening, δ, of the gate member is smaller and the change rage of the movement quantity, Δδ, relative to the drive quantity, x, is made larger when the degree of opening, δ, of the gate member is larger. Through such construction, it is possible to let the degree of mixing change at a constant change rate relative to the drive quantity of the drive means.
