Publication number: 20210209316Abstract: An agent system includes a first memory and a first processor coupled to the first memory. The first processor analyzes contents of a verbal question, and caries out pre-processing that replaces vocabulary, which is used in the contents of the question, with homogenized vocabulary, and generates response information based on results of analysis. In a case in which there exists substitution vocabulary that has replaced original vocabulary in the pre-processing, the first processor changes the response information such that it can be recognized that the substitution vocabulary in the response information is synonymous with the original vocabulary, and outputs the response information.Type: ApplicationFiled: November 12, 2020Publication date: July 8, 2021Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Chikage KUBO, Keiko NAKANO, Eiichi MAEDA, Hiroyuki NISHIZAWA

Publication number: 20210193129Abstract: In cases in which a confidence score of an inferred intent label is a predetermined threshold or less, an intent inference section searches for whether or not wording pertaining to a location, such as “on the door”, is present in a question. In cases in which a word relating to a location is present, the intent inference section consults individual function identification data associated with OM item codes in order to find intent labels including individual functions relevant to the location (such as “door”). In cases in which an intent label including an individual function relevant to the “door” is found, an OMA interaction control section consults QA data to find and acquire associated response information based on the found intent label and the OM item code, and notifies a HMI interaction control section of such response information.Type: ApplicationFiled: November 30, 2020Publication date: June 24, 2021Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Chikage KUBO, Keiko NAKANO, Eiichi MAEDA, Hiroyuki NISHIZAWA

Patent number: 9490687Abstract: A rotational difference is generated between a first and a second rotor and a third rotor, which causes an induced current to flow in a first rotor winding. This causes a torque to act between the first rotor and the third rotor. The rotary magnetic field generated by the induced current flowing through a second rotor winding interacts with a second stator, which in turn generates an induced electromotive force in a second stator winding. The induced electromotive force is applied via a phase adjustment circuit to a first stator winding, which generates a rotary magnetic field and causes a torque to act between the first stator and the third rotor. The rotary magnetic field generated by the second rotor winding and the induced current flowing in the second stator winding causes a torque to act between the second stator and the second rotor.Type: GrantFiled: April 29, 2014Date of Patent: November 8, 2016Assignees: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHO, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takao Watanabe, Eiji Tsuchiya, Hiroyuki Nishizawa, Takeshi Kitahata

Patent number: 8596246Abstract: A fuel rail for high-pressure direct-injection internal combustion engines has an injector holder and a fastening bracket directly attached to a main body of the fuel rail. Thermal deformation may occur at the time of temporary fitting or brazing when assembling the rail. However, positional accuracy of the injector holder can be assured, which results in having an excellent sealing property. Components of the fuel rail for direct-injection internal combustion engines are made of steel or stainless steel, and the components are joined reciprocally by brazing. The components joined by brazing are finished by cutting work and/or burnishing processing after the brazing step.Type: GrantFiled: June 25, 2009Date of Patent: December 3, 2013Assignee: Usui Kokusai Sangyo Kaisha LimitedInventors: Hiroyuki Nishizawa, Haruo Nishihara, Shoichiro Usui, Koichi Hayashi, Hikari Tsuchiya
