Publication number: 20230058107Abstract: With a laser decoration method for forming a painting film layer on a surface of a metal base material, and irradiating the painting film layer with a laser beam LB, thereby applying decoration, the decoration part is effectively colored by a simple process, which enables decoration with high visibility while omitting a complicated process. The problem was solved by a production method of a decorated aluminum base material characterized by including a process of forming a painting film layer on a surface of an aluminum base material, a process of partially exposing the surface of the aluminum base material by irradiation with a laser beam, and a process of subjecting the surface of the aluminum base material to an oxide film forming treatment, wherein a colored oxide film is formed on the exposed surface of the aluminum base material by the oxide film forming treatment.Type: ApplicationFiled: December 22, 2020Publication date: February 23, 2023Applicant: TOYO SEIKAN CO., LTD.Inventors: Ryotaro ISOMURA, Shuji NAKANO, Satoru KITO, Atsushi KOMINAMI

Patent number: 10344161Abstract: A polylactic acid composition including polylactic acid and an ethylene resin, characterized in that the ethylene resin is selected so that a melt flow rate ratio (RMF), defined by the following equation (1): RMF=APLA/BPE (1) where APLA represents the melt flow rate of the polylactic acid measured at 210° C. and 2.16 kg, and BPE represents the melt flow rate of the ethylene resin measured at 190° C. and 2.16 kg, in a range of 0.5 to 10 is satisfied. Also disclosed is a stretch-molded bottle formed using the polylactic acid composition. The polylactic acid composition is preferably used in molding a container particularly improved in alkali resistance and environmental stress crack resistance.Type: GrantFiled: August 6, 2015Date of Patent: July 9, 2019Assignee: TOYO SEIKAN CO., LTD.Inventors: Takuro Ito, Hiroaki Sugioka, Takahiro Okubo, Satoru Kito, Junko Tanabe

Patent number: 9845175Abstract: A polylactic acid formed body including a polylactic acid base material (1) and a hydrocarbon film (3) vapor-deposited on the surface of the base material by a plasma CVD method. The polylactic acid base material (1) exhibits a sharp X-ray diffraction peak in which a half-width of peak appearing in the 10°-25° wide angle X-ray measurement is not more than 1.22°, and the hydrocarbon film (3) is vapor-deposited on the surface of the polylactic acid base material (1), and includes two layers of a high CH2 layer (3a) having a ratio of CH2 per the total of CH, CH2 and CH3 of not less than 40% and a low CH2 layer (3b) formed on the high CH2 layer (3a) and having a ratio of CH2 per the total of CH, CH2 and CH3 of not more than 35%.Type: GrantFiled: February 4, 2013Date of Patent: December 19, 2017Assignee: TOYO SEIKAN GROUP HOLDINGS, LTD.Inventors: Takuro Ito, Satomi Ozawa, Satoru Kito, Kazuhiko Yamazaki

Patent number: 5861217Abstract: Disclosed are a composite material having an anti-wear property and a process for producing the same. The composite material includes a matrix of a low melting point Sn alloy having a melting point of from 80.degree. to 280.degree. C., and metallic dispersing particles dispersed in the matrix in an amount of from 10 to 50% by volume. When the composite material is utilized to make a rough mold for preparing a prototype, it sharply improves the anti-wear property of the rough mold, and it can be re-used for a plurality of times without adversely affecting the sharply improved anti-wear property. The composite material provides the advantages effect best when the metallic dispersing particles are Fe-C alloy dispersing particles and/or Fe-W-C alloy dispersing particles which were subjected to a surface treatment including an Sn or Ni electroplating followed by a ZnCl.sub.2 .cndot.NH.sub.4 Cl flux depositing.Type: GrantFiled: November 8, 1996Date of Patent: January 19, 1999Assignees: Toyota Jidosha Kabushiki Kaisha, Nisshin Steel, Co., Ltd.Inventors: Satoru Kito, Masahito Ito, Fuminori Matuda, Eiki Takeshima, Yasuji Tanaka, Takahiro Fujii, Kenjiro Izutani
