Publication number: 20240126280Abstract: An automatic driving system includes a control device that controls automatic driving of a vehicle, and a storage device that contains external environment information indicating an external environment of the vehicle. A driving transition zone is a zone in which a driver of the vehicle takes over at least a part of driving of the vehicle, from the control device. A termination target velocity is a target velocity of the vehicle at an end point of the driving transition zone. The control device variably sets the termination target velocity, depending on the external environment at the end point or the external environment surrounding the end point. Then, the control device controls the velocity of the vehicle in the driving transition zone, such that the velocity of the vehicle at the end point is the termination target velocity.Type: ApplicationFiled: December 26, 2023Publication date: April 18, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takaaki TANAKA, Kenichiro AOKI, Masayuki KATOH

Patent number: 10748822Abstract: A method for manufacturing a semiconductor device having a trench gate structure is provided. In the method, a first voltage-current characteristic indicating a relation between the main current and the gate voltage under a first temperature is measured to calculate a first threshold voltage. A second voltage-current characteristic indicating a relation between the main current and the gate voltage under a second temperature different from the first temperature is measured to calculate a second threshold voltage. It is determined whether the semiconductor device is a non-defective product or a defective product based on whether a difference between the second threshold voltage and the first threshold voltage is larger than a determination threshold value.Type: GrantFiled: July 10, 2019Date of Patent: August 18, 2020Assignee: DENSO CORPORATIONInventors: Takaaki Aoki, Masakazu Itoh

Patent number: 9881815Abstract: A substrate cleaning method for removing particles adhered to a substrate includes: acquiring particle information including diameters of the particles adhered to the substrate; controlling, based on the acquired particle information, a factor related to sizes of gas clusters having aggregates of atoms or molecules of a cleaning gas; ejecting the cleaning gas, at a higher pressure than a processing atmosphere where the substrate is provided, to the processing atmosphere and generating the gas clusters by adiabatic expansion; and removing the particles by irradiating the gas clusters in a perpendicular direction to a surface of the substrate. As a result, even if recesses for a circuit pattern are formed on the surface of the substrate, the particles in the recesses can be removed at a high removal rate.Type: GrantFiled: February 25, 2013Date of Patent: January 30, 2018Assignees: Tokyo Electron Limited, Kyoto UniversityInventors: Jiro Matsuo, Toshio Seki, Takaaki Aoki, Kazuya Dobashi, Kensuke Inai, Misako Saito

Publication number: 20140299465Abstract: In a method of irradiating a gas cluster ion beam on a solid surface and smoothing the solid surface, the angle formed between the solid surface and the gas cluster ion beam is chosen to be between 1° and an angle less than 30°. In case the solid surface is relatively rough, the processing efficiency is raised by first irradiating a beam at an irradiation angle ? chosen to be something like 90° as a first step, and subsequently at an irradiation angle ? chosen to be 1° to less than 30° as a second step. Alternatively, the set of the aforementioned first step and second step is repeated several times.Type: ApplicationFiled: June 17, 2014Publication date: October 9, 2014Inventors: Akinobu SATO, Akiko SUZUKI, Emmanuel BOURELLE, Jiro MATSUO, Toshio SEKI, Takaaki AOKI

Patent number: 8757237Abstract: In a blind with two shields, it is possible to perform different operations by operating one operating means and reduce the dimension of an operating device by reducing the number of parts. The operating device comprises an operating shaft rotated upon receiving an operation force, a clutch rotating integrally with the operating shaft and axially sliding on the operating shaft, and a first transmission member 50 and a second transmission member disposed at both axial sides of the clutch to transmit driving force to a first driving shaft and a second driving shaft, respectively. The sliding direction of the clutch is determined by the rotational direction of the operating shaft, such that as the clutch sliding on the operating shaft is engaged with one of the transmission members and, the rotation of the operating shaft is transmitted to any one of the driving shafts and through one of the transmission members and.Type: GrantFiled: March 23, 2011Date of Patent: June 24, 2014Assignee: Nichibei Co., Ltd.Inventor: Takaaki Aoki
