Patent number: 10473266Abstract: A high-pressure tank in which a liner can be formed using the conventionally used material, a decrease in the volumetric efficiency within the liner can be suppressed, and influence of a temperature rise due to adiabatic compression on the liner can be significantly alleviated. The tank includes a liner that suppresses permeation of gas; a valve device that allows the inside of the liner and the outside of the tank to communicate with each other and blocks communication therebetween; and an inner container with a through-hole disposed within the liner such that a gap is formed between the inner container and an inner periphery of the liner. The first communication channel of the valve device connects with a pipe extending in the gap and having holes therein. Gas supplied to the valve device is supplied into the gap from the holes in the pipe, and fills the inner container in a high-pressure state from the gap through the through-hole in the inner container.Type: GrantFiled: January 23, 2018Date of Patent: November 12, 2019Assignee: Toyota Jidosha Kabushiki KaishaInventor: Toshiyuki Kondo

Publication number: 20190213887Abstract: A target pedestrian who is present within a range of a predetermined distance from a roadway is detected. Whether or not the target pedestrian has gazed at a crossing destination and whether or not the target pedestrian has performed a safety confirmation regarding vehicles traveling on the roadway are determined based on a gaze direction of the target pedestrian. As a result, when the target pedestrian has performed one action of either of gazing at the crossing destination and the safety confirmation, and then performed the other action within a predetermined amount of time, the target pedestrian is detected as a pre-crossing pedestrian who has an intention to cross the roadway. Consequently, a pedestrian who is attempting to cross the roadway can be accurately detected at a stage before the pedestrian actually starts crossing.Type: ApplicationFiled: June 5, 2017Publication date: July 11, 2019Applicant: DENSO CORPORATIONInventors: Shinya KITAYAMA, Hirokazu OYABU, Masaaki HIROSE, Toshiyuki KONDO, Tadashi KAMADA
