Patent number: 11971327Abstract: A blowby gas treatment device includes a pressure control valve, a fresh air induction pipe, a first blowby gas pipe, a second blowby gas pipe, a shutoff valve, a one-way valve, and a PCV valve. A leak diagnosis includes a first-stage diagnosis to determine whether or not falling of a pressure in a crank case after closing of the shutoff valve under a non-supercharging condition is normal. A second-stage diagnosis is implemented by using an air fuel ratio feedback control, and determining whether or not a sensed intake air quantity obtained by an air flow meter is equal to an actual intake air quantity flowing into a cylinder set. When the sensed intake air quantity is equal to the actual intake air quantity, presence of an in-system leak is determined, and when the actual intake air quantity is larger, presence of an out-of-system leak is determined.Type: GrantFiled: June 2, 2020Date of Patent: April 30, 2024Assignee: NISSAN MOTOR CO., LTD.Inventors: Toshihiro Yamagata, Akihito Takahashi, Shimpei Yamashita

Publication number: 20230289618Abstract: A computer-implemented method, system and computer program product for knowledge graph embedding. A node pair for each triple of a knowledge graph is selected and a direct relation path between the selected node pair is identified. Furthermore, for each triple, a set of relation paths between the selected node pair is collected except for a path representing the direct relation path. The number of occurrences of each relation path for each triple in the collected set of relation paths is counted thereby forming a feature vector set for each triple, where the feature vector set includes a set of occurrences of each relation path for a node pair along with a corresponding direct relation path. A prediction model is then constructed using the feature vector set for each triple to predict an unknown direct relation path between two target nodes in the knowledge graph.Type: ApplicationFiled: March 9, 2022Publication date: September 14, 2023Inventor: Toshihiro Takahashi
