Patent number: 10989123Abstract: A blowback air amount is an amount of air that is part of the air that has flowed into a combustion chamber and is blown back into an intake passage before an intake valve closes. If the blowback air amount increases, a controller causes a fuel injection valve to inject fuel by an amount increased with respect to a fuel amount for a case in which the blowback air amount remains constant. The controller sets an increase amount of fuel injected from the fuel injection valve to a greater value when the stoichiometric air-fuel ratio of the fuel injected from the fuel injection valve is small than when the stoichiometric air-fuel ratio of the fuel injected from the fuel injection valve is great.Type: GrantFiled: July 30, 2019Date of Patent: April 27, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yoshikazu Yamamoto, Kazuya Ohshima, Masaya Kubo, Yuichiroh Yamanaka

Patent number: 10550792Abstract: A fuel injection control device for an engine includes an ECU. The ECU is configured to: change a port injection ratio in accordance with an operation state of the engine; execute correction of the total fuel injection amount by reflecting a correction amount in a basic fuel injection amount depending on the operation state when the port injection ratio is changed; and when the ECU changes the port injection ratio and calculates a second correction amount that is the correction amount having one of the positive and negative values during the execution of the correction based on a first correction amount that is the correction amount having the other one of the positive and negative values, limit reflection of the first correction amount in the basic injection amount.Type: GrantFiled: October 19, 2018Date of Patent: February 4, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masaya Kubo, Kazuya Ohshima, Yoshikazu Yamamoto, Yuichiroh Yamanaka

Publication number: 20190336318Abstract: A high-quality menstrual cup that can be used repeatedly and is comfortable when used. The menstrual cup has a head portion, a body portion, and a handle portion that are formed of the same silicone resin. This silicone resin has sufficient elasticity to permit the above portions to be deformable upon application of an external holding force by a user's fingers as well as structural restoration when the applied external force is removed. The head portion and the body portion are integrally formed, and a receiving space having a bottom is formed inside the head portion and the body portion. The receiving space has an opening on the upper side that allows menstrual blood to flow inward from the the opening (6), so that the menstrual blood can be received in the receiving space (5).Type: ApplicationFiled: September 20, 2017Publication date: November 7, 2019Applicant: Imari Co., Ltd.Inventor: Masaya KUBO

Patent number: 10336181Abstract: A grille shutter device includes a fin unit including slat members inside an opening provided at a part of a decorative side of a vehicle front. The fin unit is configured to selectively assume a closed state and an open state, and the closed state is a state where the slat members are each disposed so as to close the opening in a vehicle front view. The open state is a state where the slat members have been moved from respective positions in the closed state to a vehicle rear side of the opening and arrayed in a row substantially along a vehicle front-rear direction.Type: GrantFiled: October 22, 2018Date of Patent: July 2, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masaya Kubo, Hitoshi Aoyama, Tatsuya Shimizu, Soichiro Matsui

Patent number: 5046068Abstract: In testing the fault handling function of a multi-processor system including a master processor, a slave processor, a storage control unit shared by these processors, and a service processor, the master processor and the slave processor cooperate to synchronize with each other issuing to the storage control unit successive storage access requests all designating the same storage area. The master processor also requests the service processor to generate a pseudo-fault in the above-mentioned storage area while these access requests are being successively issued in synchronism. Upon detecting a fault, the master processor collects and examines fault information, and outputs it when an abnormal result is detected.Type: GrantFiled: April 18, 1989Date of Patent: September 3, 1991Assignee: Hitachi, Ltd.Inventors: Masaya Kubo, Kaoru Suzuki
