Patent number: 9261528Abstract: An impact detecting device includes a first impact detecting portion, a determining portion and an informing portion. The first impact detecting portion detects an impact applied to an object equipped to a vehicle. The determining portion determines that the object has received the impact when a detection result of the first impact detecting portion is greater than a first impact determination threshold. The informing portion informs that the object has received the impact, when the determining portion determines that the object has received the impact.Type: GrantFiled: March 24, 2014Date of Patent: February 16, 2016Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yasuo Imamura, Tateki Takayama, Yasuki Otake, Tomoaki Nakashima, Norihiko Nagae, Tsutomu Kondo, Yujiro Miyata

Patent number: 8838342Abstract: A mobile body capable of improving the accuracy of collision judgment. The mobile body including a fuel cell system has a first sensor which detects a physical quantity concerning the moving state of the mobile body, a second sensor which detects a physical quantity concerning the operation state of the fuel cell system, and a judgment section which receives detection signals from the first and second sensors to judge the presence of the collision of the mobile body based on the two detection signals. The judgment section can change a threshold value to be compared with the detected value of the first sensor in accordance with the detected value of the second sensor, to judge the presence of the collision of the mobile body. The first sensor can be constituted of an acceleration sensor, and the second sensor can be constituted of a gas pressure sensor or the like.Type: GrantFiled: July 10, 2008Date of Patent: September 16, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kazuya Murata, Tomoaki Nakashima

Patent number: 7758983Abstract: A process of disassembling a fuel cell 10 supplies a fluid to both a fuel gas conduit 6g and an oxidizing gas conduit 7g. Since outlets of the respective gas conduits 6g and 7g are shielded, the internal pressure or in-passage pressure of the respective gas conduits 6g and 7g gradually rises and eventually exceeds a specific in-passage pressure level for power generation of the fuel cell 10. The high in-passage pressure expands a gas diffusion electrode 4b of a membrane electrode assembly (MEA) 2 and a separator 6, which define the fuel gas conduit 6g, in opposite directions to make a clearance between the gas diffusion electrode 4b and the separator 6. Similarly the high in-passage pressure expands a gas diffusion electrode 5b of the MEA 2 and a separator 7, which define the oxidizing gas conduit 7g, in opposite directions to make a clearance between the gas diffusion electrode 5b and the separator 7.Type: GrantFiled: December 24, 2004Date of Patent: July 20, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiroshi Suzuki, Go Tejima, Tomoaki Nakashima, Ryo Akagawa

Patent number: 7754371Abstract: Respective heaters 21 through 24 receive power supply and start heating. The heaters 21 through 24 keep heating sealing layers 8 to or over a softening temperature at which the sealing layers 8 are softened or molten. After the sealing layers 8 are softened or molten to weaken the adhesive force between a pair of separators 6 and 7, the heaters 21 through 24 are detached from a fuel cell 10. The worker then completely separates the pair of separators 6 and 7 from each other with some tool or by hand and removes an MEA 2 from the fuel cell 10.Type: GrantFiled: February 2, 2005Date of Patent: July 13, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiroshi Suzuki, Nobuo Yodoshi, Go Tejima, Tomoaki Nakashima, Ryo Akagawa

Publication number: 20080152987Abstract: A fuel cell system of the invention includes a tubular switching member 70 with slits 70a to shift their position and thereby vary an opening area of outlets of oxidizing gas conduits 36 in respective unit fuel cells 30 constituting a fuel cell stack 20. The system further includes a drive roller 74 and a stepping motor 79 that function to change over the position of the slits 70a. An electronic control unit controls rotation of the stepping motor 79 to actuate the tubular switching member 70 first to narrow the opening area of the outlets of the oxidizing gas conduits 36 to or toward 0 and then to widen the opening area of the outlets of the oxidizing gas conduits 36, thereby generating pulsation in the oxidizing gas conduits 36. Water droplets flocculated in the oxidizing gas conduits 36 are thus discharged to the outlets with high efficiency. The structure of the embodiment does not require any bypass in the respective unit fuel cells 30.Type: ApplicationFiled: March 26, 2004Publication date: June 26, 2008Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomoaki Nakashima, Haruyuki Nakanishi, Shinichi Matsumoto
