  • Patent number: 8394181
    Abstract: A permselective material has a polymer having an organosiloxane skeleton and containing a dispersed solid additive. When oxygen and nitrogen are passed through a membrane having the permselective material, the relation between the permeability coefficients [cm3·cm·sec?1·cm?2·cmHg?1] of oxygen and nitrogen at a temperature of 23±2° C. under a pressure difference of 1.05 atm to 1.20 atm through the membrane is expressed by Formula (1): 0.94 ? P ? ( O 2 ) P ? ( N 2 ) < 1 ( 1 ) where P(O2) denotes the permeability coefficient of oxygen, while P(N2) denotes the permeability coefficient of nitrogen.

  • Publication number: 20120003916
    Abstract: A ventilating device includes a housing; a gas concentration detector; a passage portion defining an outside air passage and an inside air passage; a permeable membrane disposed at an interface between the outside air passage and the inside air passage; an air sending portion to generate at least one of a flow of outside air in the outside air passage and a flow of inside air in the inside air passage; and a controller. The controller controls at least one of the flow of inside air and the flow of outside air by controlling the air sending portion, based on a gas concentration of a predetermined gas detected by the gas concentration detector.

  • Publication number: 20120000363
    Abstract: An air filter device includes a permeation film arranged at a boundary portion between an outside air passage and an inside air passage, such that one side surface of the permeation film is exposed to outside air in the outside air passage and the other side surface of the permeation film is exposed to inside air in the inside air passage. The permeation film is configured such that specific gas passes through the permeation film between the outside air passage and the inside air passage. Furthermore, a turbulent flow generation portion is provided to generate a turbulent flow in at least one of the outside air flowing through near the one side surface of the permeation film and the inside air flowing through near the other side surface of the permeation film.

  • Patent number: 7763214
    Abstract: A reforming device includes a reforming part that subjects a hydrocarbon-based raw material to be reformed to a reforming reaction to form a reducing agent to be supplied to a reducing catalyst for reducing nitrogen oxide selectively. The reforming part has a reforming reaction region through which the raw material to be reformed passes and is reacted with supplied hydrogen atoms supplied so as to be reformed to the reducing agent. For example, a hydrogen permeable membrane having a first surface and a second surface may be provided in the reforming part to permeate hydrogen atoms from the first surface to the second surface and to produce the hydrogen atoms on the second surface. The reforming device can be suitably used for an exhaust gas control system for cleaning exhaust gas, for example.
