Patent number: 10539126Abstract: Reduction of noise produced by hermetic compressors. The acoustic filter includes an inlet duct, an outlet duct and a main chamber. The inlet duct includes a refrigerant fluid inlet and a refrigerant fluid delivery end. The refrigerant fluid delivery end is opposite to the refrigerant fluid inlet and it is capable of guiding the refrigerant fluid to the main chamber. The outlet duct includes a refrigerant fluid outlet and a refrigerant fluid collection end. The refrigerant fluid collection end is opposite to the refrigerant fluid outlet for guiding the refrigerant fluid from the main chamber to the fluid outlet. The filter includes a resonator chamber arranged adjacent to the inlet duct and adjacent to the main chamber. The resonator chamber and the inlet duct are fluidically connected by a resonator tube and the resonator chamber is separated from the main chamber by a sealing wall.Type: GrantFiled: June 13, 2017Date of Patent: January 21, 2020Assignee: Embraco—Industria De Compressores E Solucoes EM Refrigeracao Ltda.Inventors: Ricardo Mikio Doi, Sergio Koerich Lohn

Publication number: 20170260974Abstract: The present invention lies in the field of mechanical engineering and describes a discharge acoustic filter. Specifically, the present invention includes a discharge acoustic filter, optionally made of polymeric material in which the connections between the discharge chambers are internally disposed, in order to reduce the surface area of the discharge acoustic filter, reducing heat exchange in relation to the hermetic volume, thus, increasing thermal efficiency and reducing the energy consumption of the system.Type: ApplicationFiled: March 8, 2017Publication date: September 14, 2017Inventors: Borys Wicktor Dagostim HORBATIUK, Sergio Koerich LOHN, Ricardo Mikio DOI, Pavan PURANIK, R N Ashwin KUMAR

Patent number: 9062177Abstract: An impact resistance enhancing agent for a polylactic acid-based resin, containing a polyglycerol fatty acid ester made from a fatty acid containing at least one member selected from the group consisting of caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, and oleic acid, in an amount of 80% by mass or more of the constituting fatty acids, and a polyglycerol having an average degree of polymerization of from 2 to 40. The polylactic acid-based resin composition containing an impact resistance enhancing agent for a polylactic acid-based resin of the present invention has excellent impact resistance properties, so that the resin composition can be suitably used in, for example, agricultural materials, food wrapping materials, and other wrapping materials, and the like.Type: GrantFiled: August 18, 2011Date of Patent: June 23, 2015Assignees: TAIYO KAGAKU CO., LTD., CITY OF NAGOYAInventors: Yoshihiko Takase, Naoki Kondo, Mikio Doi, Hiroya Kuroda, Mami Nanami, Masaki Harada, Kouji Iida, Kazunori Nakano, Hideki Hayashi, Kazuaki Okamoto

Patent number: 7744698Abstract: Disclosed is a vaporizer constituted of a dispersing section 8 and a vaporizing section 22. The dispersing section 8 comprises a gas introduction port 4 for introducing a carrier gas 3 under pressure into a gas passage, means for feeding raw material solutions 5a and 5b to the gas passage, and a gas outlet 7 for delivering the carrier gas containing the raw material solutions to the vaporizing section 22. The vaporizing section 22 comprises a vaporizing tube 20 having one end connected to a reaction tube of the MOCVD system and having the other end connected to the gas outlet 7 of the dispersing section 8, and heating means for heating the vaporizing tube 20. The vaporizing section 22 serves to heat and vaporize the raw material solution containing carrier gas 3 delivered from the dispersing section 8. The dispersing section 8 includes a dispersing section body 1 having a cylindrical hollow portion, and a rod 10 having an outer diameter smaller than the inner diameter of the cylindrical hollow portion.Type: GrantFiled: December 5, 2002Date of Patent: June 29, 2010Assignees: Kabushiki Kaisha Watanabe ShokoInventors: Masayuki Toda, Masaki Kusuhara, Mikio Doi, Masaru Umeda, Mitsuru Fukagawa, Yoichi Kanno, Osamu Uchisawa, Kohei Yamamoto, Toshikatu Meguro
