Patent number: 8519013Abstract: An object of the present invention is providing a method for producing formic acid under mild reaction conditions and by a simple procedure. As a means for achieving the object, the method for producing formic acid of the present invention is characterized by a reaction between carbon dioxide and hydrogen in the presence of an ionic liquid. According to the present invention, it is possible to generate formic acid effectively, because the method does not require that carbon dioxide be brought into a supercritical state and because no basic substances are required to be added to the reaction system.Type: GrantFiled: January 24, 2011Date of Patent: August 27, 2013Inventors: Masaru Nakahara, Nobuyuki Matsubayashi, Yoshiro Yasaka

Patent number: 8449862Abstract: An object of the present invention is to provide a method for producing hydrogen by using formic acid as a feedstock, which provides a solution to problems to be solved for the production of hydrogen on an industrial scale, such as problems of production cost, storability and transportability, and also offers improved convenience. The method for producing hydrogen of the present invention is characterized by heating an ionic liquid containing formic acid. The ionic liquid is preferably an ionic liquid in which a counteranion is a formate anion (i.e., formic acid salt). Such an ionic liquid is, as a medium for the production of hydrogen from formic acid as a feedstock, excellent in terms of reaction selectivity (high-purity hydrogen is produced) and reaction velocity.Type: GrantFiled: July 28, 2009Date of Patent: May 28, 2013Assignee: Masaru NakaharaInventors: Masaru Nakahara, Nobuyuki Matsubayashi, Yoshiro Yasaka

Patent number: 6422294Abstract: To obtain a high-quality cast product of a cylinder head, a proper directivity to the cooling process of the molten metal after a pouring process by utilizing the shape of a cylinder head is discussed. In a process where molten metal is injected to a casting mold cavity formed between upper and lower molds to fill it therewith so that the molten metal is solidified to form a cylinder head of an engine, a plurality of core protrusions corresponding to holes (plug holes and bolt holes) are formed in the upper mold, and a cooling means is attached to each of the core protrusions. With respect to cooling means attached to the plurality of core protrusions, those attached to the inner core protrusions comparatively closer to the center of the casting mold are designed so as to have a greater cooling capability than those attached to the outer core protrusions; therefore, with respect to the center portion and the outer portion of the casting mold cavity.Type: GrantFiled: December 15, 2000Date of Patent: July 23, 2002Assignee: Mazda Motor CorporationInventors: Akira Murata, Akihiro Nakano, Nobuyuki Matsubayashi, Takayuki Shouju, Tomoyuki Nozaki, Shigeo Yano

Patent number: 5551502Abstract: In a low-pressure casting in which molten metal is introduced into a cavity of a casting mold under a pressure applied to the surface of the molten metal according to a preset reference pressurizing pattern, the reference pressurizing pattern is corrected when that the cavity has been filled with molten metal is detected and the pressure applied to the molten metal surface is controlled according to the reference pressurizing pattern after the correction. The pressure difference between a set pressure at a predetermined time in the reference pressurizing pattern after the correction and a set pressure at the corresponding time in the reference pressurizing pattern before the correction, is calculated and a set pressure for the period up to the time the cavity is filled with molten metal in the reference pressurizing pattern for the next casting cycle is corrected on the basis of the calculated pressure difference.Type: GrantFiled: May 12, 1995Date of Patent: September 3, 1996Assignee: Mazda Motor CorporationInventors: Nobuyuki Matsubayashi, Toru Takeshita
