Publication number: 20230366362Abstract: A cylinder block includes a water jacket surrounding a cylinder of an internal combustion engine and a water jacket spacer disposed inside the water jacket. In the cylinder block, a direction toward a center of the cylinder in a radial direction of the cylinder is defined as an inner side. A direction away from the center in the radial direction of the cylinder is defined as an outer side. The water jacket spacer includes a spacer plate and a conversion portion protruding from the spacer plate in the radial direction. The conversion portion has an action surface on which a pressure of coolant flowing through the water jacket acts. The conversion portion converts a force applied to the action surface by the pressure of the coolant into a force pushing the spacer plate toward the inner side.Type: ApplicationFiled: May 9, 2023Publication date: November 16, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kazuki AKIMOTO, Takashi MATSUTANI, Kou SHIRAKIGAWA

Patent number: 10474292Abstract: An information reception device is provided with: operation surface which is adjusted to produce a characteristic index vibration by an object contact; a storage device stores candidate information (candidate information is related with the index vibration) which serves as a candidate of input information; a microphone which acquires observation information according to observation of the actual vibration arising in the surrounding environment; and a CPU. The CPU (selecting part) judges whether or not the index vibration exists in the observation information acquired. When the CPU judges that the index vibration exists, the CPU selects the candidate information which is related with the index vibration as the input information.Type: GrantFiled: September 15, 2017Date of Patent: November 12, 2019Assignees: MEGACHIPS CORPORATION, NITTO DENKO CORPORATIONInventors: Motoyasu Tanaka, Takashi Matsutani, Masayasu Yamamoto, Yuki Haraguchi, Hideo Sugawara, Ikuo Kawamoto, Motoki Haishi, Nobuyuki Kozonoi
