Publication number: 20240238848Abstract: A substrate processing apparatus includes a support unit, a supply unit, an annular member, a rotation unit, a cover member, and an annular flow regulation member disposed above the cover member. The annular member includes an inclined surface inclined downward toward a center of the annular member in a radial direction. The flow regulation member includes a base portion and a protrusion which faces a circumferential portion of the substrate supported on the support unit and protrudes from the base portion toward the circumferential portion of the substrate. The protrusion overlaps the support unit when viewed in a vertical direction. A lower surface of the protrusion is positioned above an upper surface of the substrate supported on the support unit and positioned below an upper surface of the annular member. An inner circumferential surface of the protrusion is inclined radially outward from an upper side to a lower side.Type: ApplicationFiled: January 11, 2024Publication date: July 18, 2024Inventors: Takafumi KINOSHITA, Yuki ITO, Daisuke SAIKI, Tomoyuki HASHIMOTO, Yoshifumi AMANO, Kazuhiro AIURA, Akira FUJITA, Shuhei TAKAHASHI

Patent number: 9970827Abstract: A fuel temperature estimation device that can improve the estimation accuracy of a fuel temperature in each part of a fuel channel, is provided. In the invention, the fuel temperature estimation device estimates the fuel temperature of each part of the fuel channel in a vehicle (for example, an injection nozzle, a pressure accumulator, a high-pressure pump), and includes a flow rate measuring device that measures a fuel flow rate of a fuel return system of the fuel channel and a controller. The controller includes a fuel temperature correction unit that corrects an estimated fuel temperature in a fuel injection system based on the fuel flow rate of the fuel return system, and has a function of estimating the fuel temperature using the fuel flow rate of the fuel return system as a parameter.Type: GrantFiled: June 9, 2015Date of Patent: May 15, 2018Assignee: VOLVO TRUCK CORPORATIONInventors: Shigemi Kobayashi, Kazuhiro Kujirai, Masahiro Misawa, Takafumi Amano, Yousuke Aoyama
