Publication number: 20070244568Abstract: Decellularization of tissue by means of an amphipathic solvent a well-established practice. However, situations exist where the provision of enhanced decellularization is preferred. There is a demand for treating methods for coping with such situations. Thus, it is intended to provide a method for enhancing decellularization. The method comprises not only the immersing of a tissue in a solution containing an amphiphilic molecule in non-micellar form (for example, 1,2-epoxide polymer) but also performing a radical reaction (for example, treatment selected from the group consisting of exposure to gamma-ray irradiation, ultraviolet irradiation, a free radical supply source, ultrasonication, electron beam irradiation, and X-ray irradiation).Type: ApplicationFiled: December 24, 2004Publication date: October 18, 2007Applicants: Cardio Incorporated, National Institute of Advanced Industrial ScienceInventors: Hikaru Matsuda, Yoshiki Sawa, Satoshi Taketani, Shigeru Miyagawa, Shigemitau Iwai, Takeyoshi Ota, Jun Miyake, Masayuki Hara, Masakazu Furuta, Eiichiro Uchimura

Patent number: 6200642Abstract: A corrosion-resistant and brazeable aluminum material. has an aluminum core, and a thermally sprayed layer formed on the core is composed of a brazing metal intermingled with zinc or its alloy. The brazing metal may be a mixture of aluminum and silicon, an aluminum-silicon alloy, a blend of the mixture with the alloy, or silicon. The brazeable aluminum material may be produced by blending a first powder of the brazing metal with a second powder of a corrosion resistant substance including zinc, so as to prepare a powder mixture, and then thermally spraying the powder mixture onto the aluminum core.Type: GrantFiled: October 17, 1995Date of Patent: March 13, 2001Assignee: Showa Aluminum CorporationInventors: Tomiyoshi Kanai, Masakazu Furuta, Masahiro Kojima, Masafumi Ueda

Patent number: 6109510Abstract: A brazing material that has a low melting point and can braze aluminum materials at a low temperature with a good wetting property is disclosed. The brazing material can include a matrix composed of Zn, a Zn--Al alloy or a Al--Zn--Si alloy having a low melting point each preferably containing 0.001 to 3.0 wt % of rare-earth element. When such a brazing material is used, aluminum materials can be brazed at a temperature of 580.degree. C. or below.Type: GrantFiled: May 18, 1998Date of Patent: August 29, 2000Assignee: Showa Aluminum CorporationInventors: Ryotatsu Otsuka, Masakazu Furuta, Yuji Asano

Patent number: 5947365Abstract: A process for producing a flat heat exchange tube having opposed upper and lower walls and a plurality of reinforcing walls connected by brazing between the respective upper and lower walls for dividing the tube interior into parallel fluid passages. In order to strengthen the brazed connection between the reinforcing walls and the lower surface of the upper wall and to prevent the creation of a clearance space therebetween, the lower surface of the upper wall is provided in advance with longitudinally extending ridges with which the upper surfaces of the reinforcing walls come in contact to eliminate the clearances and thus insure the existence of a continuous brazed connection between each reinforcing wall and lower surface of the upper wall.Type: GrantFiled: June 25, 1997Date of Patent: September 7, 1999Assignee: Showa Aluminum CorporationInventors: Daishi Tanaka, Masakazu Furuta, Kazuyuki Takahashi, Yasuhiro Osame

Patent number: 5594930Abstract: A brazeable aluminum material is composed of an aluminum core and a brazing agent layer consisting of a brazing agent thermally sprayed onto covering a surface of the core. A number of unmolten minute particles of the brazing agent are present in the brazing agent layer, which contains at least an aluminum-silicon alloy and/or a mixture of aluminum and silicon. Characteristic features of a method of producing the brazeable aluminum material are the steps of: preparing a powder composed of minute particles; and thermally spraying the powder onto the aluminum core in such a state that only a surface of each minute particle is molten, with a pith of the particle remaining unmolten. The powder is an Al-Si alloy and/or a mixture of Al powder and Si powder.Type: GrantFiled: October 27, 1993Date of Patent: January 14, 1997Assignee: Showa Aluminum CorporationInventors: Takashi Terada, Masahiro Kojima, Taizo Morita, Katsuyuki Arakawa, Ichiro Iwai, Masakazu Furuta

Patent number: 5497461Abstract: A main CPU in a data transmitting section applies a packet number recorded in a packet number memory to a block data when transmitting the latter, and increments and updates the packet number upon completion of the transmission. A sub-CPU in a data receiving section determines whether the packet number applied to the block data received is the updated number or not, in order to determine whether the data is a re-transmission of previous data or a transmission of new data. If the block data received is a re-transmission of previous data, the data received previously is discarded. If the block data received is new data, the data received previously is processed.Type: GrantFiled: June 22, 1993Date of Patent: March 5, 1996Assignee: Irem CorporationInventors: Shigekazu Matsumoto, Masakazu Furuta
