Patent number: 7976700Abstract: A water separation unit includes a water separation portion. The water separation portion includes a component separation wall, a liquid chamber, and a gas chamber. The separation wall divides the water separation portion between the liquid chamber and the gas chamber. Liquid fuel is led to the liquid chamber. The separation wall includes a separation membrane, which water selectively permeates to be separated from liquid fuel in the liquid chamber. Water passing through the separation wall is temporarily stored in the gas chamber. A fuel supply apparatus supplies liquid fuel in a fuel tank to an internal-combustion engine. The apparatus includes the water separation unit. The water separation portion is disposed integrally in one of the fuel tank and a passage leading from a filler opening into the fuel tank, such that the liquid chamber is located above the gas chamber in a vertical direction of the water separation portion.Type: GrantFiled: December 4, 2007Date of Patent: July 12, 2011Assignee: Denso CorporationInventors: Miyao Arakawa, Yoshiaki Nishijima, Masatoshi Kuroyanagi, Yoshimichi Kiyozumi

Patent number: 7493897Abstract: A fuel supply apparatus includes a component adjustment unit, a low-pressure side passage, and a valve. The unit adjusts component composition of fuel by separating a particular component from fuel. The unit includes a component separation wall, which divides an interior of a portion of a fuel supply passage between an anterior chamber and a posterior chamber. The wall includes a separation membrane, which the particular component of fuel in the anterior chamber selectively permeates to be separated. The particular component after passing through the wall is temporarily stored in the posterior chamber. When the low-pressure side passage connected to the posterior chamber is opened by the valve, the particular component is separated. Fuel, from which the particular component is separated, is supplied to an injection valve from the anterior chamber. When the low-pressure side passage is closed by the valve, the separation of the particular component is restricted.Type: GrantFiled: October 17, 2007Date of Patent: February 24, 2009Assignee: Denso CorporationInventors: Miyao Arakawa, Yoshiaki Nishijima, Masatoshi Kuroyanagi, Yoshimichi Kiyozumi

Publication number: 20090005543Abstract: The present invention provides a method for refolding protein produced, for example, by Escherichia coli, that is inactive due to an as yet unformed higher order structure, or protein deactivated due to a change in conformation for some reason. The invention comprises a method, refolding kit, refolding agent, and molding that activate a native function or activity inherent to a protein through treatment with zeolite beta of protein produced, for example, by Escherichia coli, that is inactive due to an as yet unformed higher order structure, or protein deactivated due to a change in conformation for some reason. The invention also comprises a method for producing an active protein that utilizes the same. As compared with conventional methods, the present invention can provide a novel method for activating protein function that is highly versatile and generalizable, that employs a simple and easy protocol, and that is inexpensive and enables repeated use of the function activator.Type: ApplicationFiled: September 4, 2008Publication date: January 1, 2009Applicant: National Inst of Adv Industrial Science and Tech.Inventors: Fujio MIZUKAMI, Yoshimichi Kiyozumi, Takuji Ikeda, Akiko Kawai, Takako Nagase, Kengo Sakaguchi, Hiroyuki Chiku

Publication number: 20080283019Abstract: An anterior chamber receives a mixture fluid, in which a lubricant oil and a fuel are mixed. A semipermeable separation film is permeable to the fuel component in the anterior chamber and is not permeable to the lubricant oil in the anterior chamber due to a molecular size difference between the lubricant oil and the fuel, so that the semipermeable separation film selectively separates the fuel component from the mixture fluid. A posterior chamber is placed on an opposite side of the semipermeable separation film, which is opposite from the anterior chamber. The posterior chamber receives the separated fuel component, which is separated by the semipermeable separation film.Type: ApplicationFiled: May 12, 2008Publication date: November 20, 2008Applicant: DENSO CORPORATIONInventors: Miyao ARAKAWA, Masatoshi Kuroyanagi, Yoshiaki Nishijima, Yoshimichi Kiyozumi
