Patent number: 8206653Abstract: To provide an organic synthesizer that can conduct a pressure reaction and an atmospheric reaction in one organic synthesizer. An organic synthesizer comprising a reaction vessel support part (160), which can support two or more reaction vessels, and pressure regulation means (164) for regulating the pressure within the reaction vessel supported by the reaction vessel support part (160) by supplying/discharging gas. Two or more pressure regulation means (164) are provided for each reaction vessel supported by the reaction vessel support part (160). At least one pressure regulation means (164A) in the two or more pressure regulation means (164) is constructed so as to be detachable from and attachable to the other pressure regulation means (164B). The gas supply/discharge pipes (174a to 174d) are constructed so that a part near the front end can be flexed in a vertical direction and in a lateral direction.Type: GrantFiled: October 11, 2010Date of Patent: June 26, 2012Assignee: Sibata Scientific Technology Ltd.Inventors: Masatoshi Shibata, Yutaka Mashiyama, Yasuyuki Suzuki, Isamu Hiruta, Toshiaki Wada, Tetsuo Tomoda

Patent number: 7892497Abstract: To provide an organic synthesizer that can conduct a pressure reaction and an atmospheric reaction in one organic synthesizer and can realize attachment of reaction vessels to the organic synthesizer and detachment of the reaction vessels from the organic synthesizer without applying any load to gas supply/discharge pipes. An organic synthesizer comprising a reaction vessel support part (160), which can support two or more reaction vessels, and pressure regulation means (164) for regulating the pressure within the reaction vessel supported by the reaction vessel support part (160) by supplying/discharging gas. Two or more pressure regulation means (164) are provided for each reaction vessel supported by the reaction vessel support part (160). At least one pressure regulation means (164A) in the two or more pressure regulation means (164) is constructed so as to be detachable from and attachable to the other pressure regulation means (164B).Type: GrantFiled: August 10, 2006Date of Patent: February 22, 2011Assignee: Sibata Scientific Technology Ltd.Inventors: Masatoshi Shibata, Yutaka Mashiyama, Yasuyuki Suzuki, Isamu Hiruta, Toshiaki Wada, Tetsuo Tomoda

Patent number: 6495061Abstract: A mixed refrigerant comprising one member selected from R-23, R-116 and a mixture thereof and one member selected from propane, butane and a mixture thereof. The mixed refrigerant allows cooling the inside of a freezer to a super low temperature, particularly to a temperature of −60° C. or lower, with a compressor of a conventional freezer. The mixed refrigerant not only has a low boiling point similar to those of R-23 and R-116, but also can be liquefied in a room temperature surrounding due to propane or butane contained therein, and further has good miscibility with a lubricating oil or the like so that a freezer unit using the refrigerant is free from the problem of clogging therein. Additionally, the mixed refrigerant has no ability to deplete ozone and is significantly low with respect to greenhouse effect.Type: GrantFiled: December 5, 2000Date of Patent: December 17, 2002Assignees: Nihon Freezer Co., Ltd., Dairei Co., Ltd.Inventors: Susumu Kurita, Toshio Seino, Isamu Hiruta, Makoto Morita
