Publication number: 20230056329Abstract: To accurately obtain operating conditions of a production facility that satisfies desired criteria. A control apparatus includes a process data acquisition unit that reads process data from a storage device that stores the process data obtained from a production facility, and a control unit that obtains an optimum solution for a predetermined adjustment target of the process data and controls the production facility on the basis of the optimum solution. The optimum solution satisfies constraint conditions and optimizes an objective function. The constraint conditions are defined by using at least some of the process data. The objective function is defined by using at least some of the process data. A learned model having learned features of the process data obtained from the production facility is further stored in a storage device on the basis of causality information that defines a combination of first process data and second process data. The first process data is used as an explanatory variable.Type: ApplicationFiled: February 4, 2021Publication date: February 23, 2023Applicant: DAICEL CORPORATIONInventors: Masahiro HAITSUKA, Hidetoshi KOZONO, Fumihiro MIYOSHI

Publication number: 20230059056Abstract: A regression model having a correspondence relationship with variation of an explanatory variable and variation of a target variable is constructed. A regression analysis device includes a data acquisition unit that reads out, from a storage device storing training data used as a target variable and an explanatory variable of a regression model and a constraint condition defining in advance whether the explanatory variable should be varied positively or negatively to vary the target variable in a positive direction or a negative direction, the training data and the constraint condition, and a coefficient update unit that repeatedly updates, using the training data, coefficients of the explanatory variable in the regression model to minimize a cost function including a regularization term that increases a cost in a case where the constraint condition is contravened.Type: ApplicationFiled: February 4, 2021Publication date: February 23, 2023Applicants: THE UNIVERSITY OF TOKYO, DAICEL CORPORATIONInventors: Hiroshi OKAMOTO, Marina TAKAHASHI, Shuji SHINOHARA, Shunji MITSUYOSHI, Hidetoshi KOZONO, Masahiro HAITSUKA, Fumihiro MIYOSHI

Publication number: 20230057943Abstract: To improve prediction accuracy of a process including a reaction in a chemical plant. A prediction apparatus includes a process data processing unit that performs a predetermined processing process on process data obtained from a chemical plant, and a prediction model generation unit that generates a prediction model having learned features of the process data obtained from the chemical plant, on the basis of causality information that defines a combination of first process data and second process data or a value corresponding to the second process data among the process data obtained from the chemical plant or the process data processed by the process data processing unit. The first process data is used as an explanatory variable. The second process data or the value corresponding to the second process data is used as a response variable. Furthermore, the process data processing unit obtains a value corresponding to a reaction rate of a processing target in a predetermined period by using the process data.Type: ApplicationFiled: February 4, 2021Publication date: February 23, 2023Applicant: DAICEL CORPORATIONInventors: Masahiro HAITSUKA, Hidetoshi KOZONO, Fumihiro MIYOSHI

Patent number: 10653842Abstract: The described technology relates to a needleless syringe for injecting an injection objective substance into an injection target area. The needleless syringe includes a protruding member which is provided movably from a first position to a second position at which 1) a protruding length of a forward end of the protruding member from an end surface of a housing is shorter than a protruding length of the forward end at the first position and 2) the forward end and a discharge port can be brought in contact with the injection target area. The needleless syringe also includes a maintaining mechanism which maintains the protruding member at the first position and a power source circuit which applies a voltage to a driving unit when the protruding member having been maintained at the first position is moved to the second position. Accordingly, the unintended discharge from the syringe is appropriately avoided.Type: GrantFiled: February 16, 2018Date of Patent: May 19, 2020Assignee: Daicel CorporationInventors: Masahiro Haitsuka, Toshiki Yagi

Patent number: 10307540Abstract: The present application relates to a needleless syringe for injecting an injection objective substance into an injection target area without using an injection needle. In one aspect, the needleless syringe includes a main syringe body containing the injection objective substance with the use of a sealing member, a pressurizing unit provided in the main syringe body and configured to pressurize the injection objective substance, a flow passage unit defining a flow passage of the pressurized injection objective substance to be discharged to the injection target area and a preparatory filling unit configured to fill the flow passage unit with a part of the injection objective substance by destroying a part of the sealing member before the injection objective substance is pressurized. According to some embodiments, it is possible to mitigate the load exerted on the nozzle during the injection and reduce the noise without deteriorating a syringe user convenience.Type: GrantFiled: September 22, 2016Date of Patent: June 4, 2019Assignee: Daicel CorporationInventors: Masahiro Haitsuka, Masayuki Ueda
