  • Patent number: 8500886
    Abstract: Exhaust gas after coal or oil burning has moisture, which hinders carbon dioxide adsorption. It is necessary to completely remove this moisture with the minimum use of energy. The exhaust gas from the burning apparatus is first lowered of its temperature by passing through an total heat exchanger rotor, and the resultant gas which has low temperature and humidity is sent to a carbon dioxide adsorption rotor, thereby removing carbon dioxide from the gas, which is then sent through the total heat exchanger rotor with the resultant desorption of moisture adsorbed there and is exhausted to outside atmosphere, while the carbon dioxide adsorption rotor is desorbed of its carbon dioxide using water vapor, with the resultant very humid carbon dioxide to be sent to a processing system such as for underground burial.

  • Publication number: 20130186277
    Abstract: An adsorption rotor has a surface layer which can be detached and replaced when performance degrades. A metal aggregate is extended in the width direction of the rotor element so that attachment-and-detachment adsorption rotor elements can be attached thereto using bolts and a perimeter griddle fixing bracket, thus resulting in protecting an upper part of the integral-type adsorption rotor element. In this way, the weight of the attachment-and-detachment adsorption rotor elements can be made light, resulting in them being fixable only using bolts, without special tools or skilled technicians. Moreover, because the detachment-and-replacement procedures can be performed from a rotor spindle side, thus from inside of a chamber, a heavy industrial machine is not required.

  • Patent number: 8439998
    Abstract: In sintering a metal powder after pressure molding into a given configuration, random amorphous flaky metal fine powders (10) are used as metal powder materials. In addition, spherical particulate metal powders 11 are used as main materials, and random amorphous flaky metal fine powders 10 having finer particle size than the metal powders 11 and produced by fracturing a metal fracture material by means of high-velocity gas swirling flow are used as sub-materials, and molding and sintering are performed in a state of dispersing the sub-materials (10) in the main materials (11). Thus, despite being a power metallurgical product, it is possible to obtain a metal product having a dense metallographic structure and excellent in properties such as mechanical strength.

  • Patent number: 8418753
    Abstract: A heat exchange tube is constructed by forming, on a cylindrical tube peripheral wall, a plurality of projecting portions which project to an inside of the tube peripheral wall, and which are formed by pushing. The plurality of projecting portions are formed, respectively, into conical shapes across a tube axis, and are arranged along virtual spirals on the tube peripheral wall. Accordingly, it is possible to provide a heat exchange tube which facilitates formation of a plurality of projecting portions with the thickness hardly changed and without formation of protruded portions, and which is capable of contributing to enhancement of heat exchanging efficiency.

  • Publication number: 20130063828
    Abstract: A junction type compound lens using glass and resin is used. By properly controlling the difference between refractive indices and the difference between Abbe numbers of the resin and glass, interface reflection that occurs when a ray with a large incidence angle is incident is restricted, and generation of a flare or a ghost image is restricted. Further, by properly controlling the difference in refractive index and the difference in Abbe number, various aberrations, such as spherical aberration, field curvature, and chromatic aberration, which may deteriorate optical performance, can be corrected. Thus, a small and high-performance imaging lens can be provided.

  • Publication number: 20120291280
    Abstract: In a manufacturing method of an impeller for a fluid transmitting device, multiple guide grooves aligned in a peripheral direction to allow communication between adjacent ones of multiple positioning holes are provided in a concave inner surface of a core in advance; and in a step of melting a brazing material and causing the molten brazing material to penetrate into gaps between coupling pieces and positioning holes that are fitted to each other and further into gaps between the core and the blades, the molten brazing material is guided to the positioning holes through the multiple guide grooves. Accordingly, the step allows the molten brazing material to be efficiently guided to the gaps between the coupling pieces and positioning holes, thereby improving the yield of the brazing material and preventing an influence of a residual brazing material over the rotational balance of the impeller.
