Publication number: 20240067180Abstract: An information distribution apparatus includes an obstacle identification apparatus that identifies an obstacle to a vehicle traveling in an area and then outputs obstacle information related to the position of the obstacle, a road database representing the positions of roads, and an impassable-road determination means that determines a road through which the vehicle cannot pass, based on the obstacle information outputted from the obstacle identification apparatus and the road database, and then outputs impassable-road information. A narrow-area automatic driving system is provided with the information distribution apparatus and the vehicle that travels from a departure point to a target point, along a route formed based on information outputted from the information distribution apparatus.Type: ApplicationFiled: January 12, 2023Publication date: February 29, 2024Applicant: Mitsubishi Electric CorporationInventors: Toshihide SATAKE, Keisuke MORITA, Takahisa AOYAGI, Hiroshi YAMADA, Toru HIGUCHI

Patent number: 11637297Abstract: A fuel cell system includes a fuel cell, a cathode off-gas discharge channel, a gas-liquid separator, and a cover member. The gas-liquid separator includes a body, a first discharge channel including a first valve seat at an end, and a first valve device including a first valve element and a first driver. The cover member covers at least the first discharge channel and the first valve seat in the gas-liquid separator, and includes a gas channel defining portion that defines a gas channel communicating with the cathode off-gas discharge channel between the cover member and the gas-liquid separator. The gas channel is configured such that a cathode off-gas flowing into the cover member comes into contact with the first discharge channel and the first valve seat and does not come into contact with the first driver.Type: GrantFiled: October 7, 2021Date of Patent: April 25, 2023Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, ASIN CORPORATIONInventors: Takami Hosoi, Hiroaki Nishiumi, Takashi Mishima, Hitoshi Okuno, Toshihide Yamada
