Publication number: 20150205149Abstract: An image display device is provided that can satisfy both transparency of a non-displaying portion and visibility of a projected image. The screen of and the image projector of the image display device are synchronized such that the image projector projects an image on a part of the screen or on the whole screen when the screen is in a light-scattering state, and projects no image when the screen is in a light-transmitting state. The screen is driven to periodically switch between a light-transmitting state and a light-scattering state at a switching frequency of 40 Hz to 100 Hz and a periodic switching duty ratio of 0.01 to 0.20.Type: ApplicationFiled: March 27, 2015Publication date: July 23, 2015Applicant: MITSUBISHI CHEMICAL CORPORATIONInventors: Noriyuki KIDA, Masami KADOWAKI

Patent number: 8163212Abstract: The present invention provides a process for producing pellet of EVOH comprising the steps of introducing an EVOH solution containing alcohol into an apparatus, contacting the solution with water in the apparatus to let out the alcohol with water and then letting out an EVOH hydrous composition from the above-mentioned apparatus (step 1); cutting the EVOH hydrous composition let out therefrom to obtain EVOH hydrous composition pellets (step 2); introducing the obtained EVOH hydrous composition pellets into a dryer to reduce a water content thereof (step 3); melt-kneading the pellets, whose water content is reduced, in an extruder (step 4); and cutting EVOH discharged from the extruder to obtain the pellet of EVOH (step 5). Thus, the EVOH hydrous composition obtained by removing alcohol without deteriorating the environment can be efficiently dried, and pellets having less thermal degradation in drying and a uniform shape can be obtained.Type: GrantFiled: July 14, 2003Date of Patent: April 24, 2012Assignee: Kuraray Co., Ltd.Inventors: Naohiko Uchiumi, Noriyuki Kida, Hiroyuki Shimo, Kaoru Ikeda

Patent number: 7524895Abstract: A method for producing an ethylene-vinyl alcohol copolymer resin composition, wherein an ethylene-vinyl alcohol copolymer resin is contacted with an aqueous solution containing both carbon dioxide gas and at least one additive selected from the group consisting of an alkali metal salt (A) and a boron compound (B). The present invention can provide an environmentally friendly method for producing an EVOH resin composition, the method releasing no carboxylic acid such as acetic acid to the ambient atmosphere. In addition, the invention can provide an EVOH resin composition which emits less smell and is superior also in long-run workability.Type: GrantFiled: February 6, 2003Date of Patent: April 28, 2009Assignee: Kuraray Co., Ltd.Inventors: Kaoru Ikeda, Noriyuki Kida, Hiroyuki Shindome, Naohiko Uchiumi

Patent number: 7473735Abstract: The present invention provides a resin composition which comprises EVOH and a thermoplastic resin other than EVOH and which generates less odor and therefore is suitable for food packaging applications. The invention also provides an environmentally friendly method for producing a resin composition, without releasing any carboxylic acid such as acetic acid to the peripheral environment. A resin composition containing less carboxylate group is obtained by contacting an ethylene-vinyl alcohol copolymer resin with an aqueous solution containing both carbon dioxide gas and at least one additive selected from the group consisting of an alkali metal salt (A) and a boron compound (B) and then melt kneading with a thermoplastic resin (G) other than EVOH.Type: GrantFiled: July 22, 2004Date of Patent: January 6, 2009Assignee: Kuraray Co., Ltd.Inventors: Naohiko Uchiumi, Kaoru Ikeda, Noriyuki Kida, Tetsuya Hara, Syukiti Kawamura
