| 20100214868 | Agitator and Agitation Method - It is an object of the present invention to provide an agitator equipped with a bottom paddle that has favorable agitation performance also in a streamline flow region of low Re number and to provide an agitation method. According to the agitator and the agitation method of the present invention, an object is agitated within an agitation tank by the use of an agitator that includes a rotating shaft that is disposed outside of the tank along the axis of a vertically oriented cylindrical agitation tank to be rotatable, and a flat agitation impeller made up of a bottom paddle, which lower end edge is formed to be of a shape that conforms with a tank bottom wall such that a specified clearance is formed between the lower end edge and the tank bottom wall, the bottom paddle being provided with a communicating portions at a positions away from the lower end edge upward by a specified amount for communicating between the front side and the rear side of the bottom paddle, and being mounted to the rotating shaft so as to locate close to the tank bottom wall and extend towards a sidewall of the tank. | 08-26-2010 |
| 20100181324 | Seal Structure of Pressure Vessel - There is provided a seal structure which surely maintains sealing performance of a pressure vessel including a bottomed tubular vessel body with an opening end and a lid closing the opening end. In this seal structure of the pressure vessel, annular grooves | 07-22-2010 |
| 20100177593 | Stirring Apparatus - An object is to provide a stirring apparatus which can exhibit excellent mixing characteristics and shorten the mixing time. The stirring apparatus includes a stirred tank having a bottomed cylindrical shape, a rotational shaft disposed coaxially or substantially coaxially within the stirred tank, a plate-shaped bottom blade having a lower end edge shaped to conform to a bottom wall surface of the stirred tank, the bottom blade having an opening for communication between one face side and an opposite face side, of the bottom blade, the ratio (h/d) between the blade height h of the bottom blade and the impeller diameter d of the bottom blade satisfies 0.4≦h/d, and the ratio of the opening area to the projection area of the bottom blade as viewed from the rotational direction thereof (opening ratio of the bottom blade) is 10-60%. | 07-15-2010 |
| 20090242184 | Spiral Tube Fin Heat Exchanger - It is an object to provide a finned tube type heat exchanger (spiral tube fin heat exchanger) capable of having a reduced size and having an increased heat exchange efficiency and, therefore, an increased performance. A spiral tube fin heat exchanger includes a plurality of heat transfer tubes that allow a heat exchanging object to flow therein and each including a radially-extending tube fin on an outer peripheral surface thereof, the plurality of heat transfer tubes being arranged to be oriented in an identical direction, wherein the tube fin has a spiral shape and has a spiral axis being coincident with a center axis of each of the heat transfer tubes, and the plurality of heat transfer tubes are arranged such that tip ends of tube fin portions in one of adjacent heat transfer tubes intrude between tube fin portions in the other one of adjacent heat transfer tubes. | 10-01-2009 |
| 20090134005 | Oven Observing Equipment and Push-Out Ram Having the Same - An oven observing equipment capable of observing the inside of an oven turned to a high temperature precisely includes: a housing | 05-28-2009 |
| 20090039606 | Bellows for Pressure Vessel - There is provided a bellows for a pressure vessel that would not rupture due to thermal expansion and contraction, avoiding stagnation of a raw material. The bellows | 02-12-2009 |
