Patent number: 9697471Abstract: A plant model management device according to one embodiment includes a generation unit and a combining unit. The generation unit receives a first set of prior probability distributions of a first set of automatic operation parameters. The first set of automatic operation parameters define a condition required for modeling a plant model that is a model based on data concerning a plant. The generation unit generates a first set of posterior probability distributions of the first set of automatic operation parameters and a first set of probabilistic plant models based on the first set of prior probability distributions. The first set of posterior probability distributions reflect compatibility with learning data that is past time-series data concerning a first explanatory variable and a first objective variable. The combining unit combines the first set of probabilistic plant models using the first set of posterior probability distributions to generate a first plant model.Type: GrantFiled: April 7, 2014Date of Patent: July 4, 2017Assignee: YOKOGAWA ELECTRIC CORPORATIONInventors: Akio Nakabayashi, Shouta Ukai, Hidehiko Wada, Tetsuya Otani

Patent number: 9676579Abstract: A manufacturing method for a glass roll includes drawing a glass film downward vertically from a forming device, converting a delivery direction of the glass film from a vertical direction to a horizontal direction, continuously delivering the glass film to a downstream side by a horizontal conveyance section, and rolling the glass film into a roll shape on a downstream side of the horizontal conveyance section. While the glass film is supported in surface contact by an endless belt serving as a support section, which is provided in the horizontal conveyance section, a rolling force equal to or less than a static friction force, which is generated by a self-weight of the glass film between the glass film and the endless belt, is imparted to the glass film.Type: GrantFiled: May 16, 2012Date of Patent: June 13, 2017Assignee: NIPPON ELECTRIC GLASS CO., LTD.Inventors: Koichi Mori, Akio Nakabayashi
