Patent number: 11310457Abstract: The present invention provides a method for manufacturing a highly reliable display device at a low cost with high yield. According to the present invention, a step due to an opening in a contact is covered with an insulating layer to reduce the step, and is processed into a gentle shape. A wiring or the like is formed to be in contact with the insulating layer and thus the coverage of the wiring or the like is enhanced. In addition, deterioration of a light-emitting element due to contaminants such as water can be prevented by sealing a layer including an organic material that has water permeability in a display device with a sealing material. Since the sealing material is formed in a portion of a driver circuit region in the display device, the frame margin of the display device can be narrowed.Type: GrantFiled: October 25, 2019Date of Patent: April 19, 2022Assignee: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.Inventors: Shunpei Yamazaki, Satoshi Murakami, Motomu Kurata, Hiroyuki Hata, Mitsuhiro Ichijo, Takashi Ohtsuki, Aya Anzai, Masayuki Sakakura

Patent number: 9862656Abstract: Provided are a method for producing paraffins and an apparatus for producing paraffins, in which each high-purity paraffin can be produced with high efficiency while complicated operations such as distillation are not carried out. An apparatus for producing paraffins includes a separation and recovery unit and a hydrogenation unit. The separation and recovery unit has a separator containing silver ions, and separates impurities from raw material olefins containing olefins as main components and recovers the olefins, by bringing the raw material olefins into contact with the separator. The hydrogenation unit brings the olefins recovered by the separation and recovery unit into contact with hydrogen in a presence of a catalyst and subjects the recovered olefins to a hydrogenation reaction, thereby obtaining high-purity paraffins.Type: GrantFiled: September 25, 2012Date of Patent: January 9, 2018Assignee: SUMITOMO SEIKA CHEMICALS CO., LTD.Inventors: Akihiro Kuwana, Jun-ichi Sakamoto, Hiroyuki Hata

Patent number: 8785710Abstract: A method for purifying a paraffin from a source material containing a paraffin having 2 to 6 carbon atoms and an olefin having 2 to 6 carbon atoms includes a first step of bringing the source material into contact with a silver ion-containing solution (absorption liquid) at a predetermined temperature and pressure in an absorption column 1 and recovering a non-absorbed gas not absorbed by the absorption liquid while the olefin in the source material is preferentially absorbed by the absorption liquid, and a second step of desorbing and discharging a gas component from the absorption liquid having undergone the first step at a predetermined temperature and pressure in a desorption column 2. The first step and the second step are performed continuously in parallel while the absorption liquid is circulated between the first step and the second step.Type: GrantFiled: December 21, 2009Date of Patent: July 22, 2014Assignee: Sumitomo Seika Chemicals Co., Ltd.Inventors: Hiroaki Nago, Shinichi Tai, Junichi Kawakami, Hiroyuki Hata, Shigeru Morimoto
