Publication number: 20230196954Abstract: A three-dimensional-image display device includes a display unit, a variable focus lens unit, and a controller. The display unit sequentially displays a first image displayed by a first image signal and a second image displayed by a second image signal, and that projects a display light of the first image and a display light of the second image. The variable focus lens unit switches the focal lengths for the display lights to respectively form, as virtual images, the first image and the second image on a first display surface and a second display surface. The controller controls, on the basis of a start timing at which writing, of an image signal of a different image, to pixels of the display unit starts, a projecting timing at which the display unit projects the display light of the first image and the display light of the second image.Type: ApplicationFiled: February 13, 2023Publication date: June 22, 2023Applicant: Wuhan Tianma Micro-Electronics Co., Ltd.Inventors: Naoyasu IKEDA, Tetsuhi Sato

Patent number: 10746294Abstract: A control device for a continuously variable transmission includes a belt type continuously variable transmission and a controller. The controller is configured to calculate an actual gear shift ratio based on rotation speed sensor values from a primary rotation speed sensor and a secondary rotation speed sensor, and to perform gear shift ratio control using feedback control to converge the actual gear shift ratio to a target gear shift ratio. The controller is further configured to stop calculation of the actual gear shift ratio when one of the rotation speed sensor values is less than a first threshold value determined based on a lower limit value of sensor detection accuracy, and stop calculation of the actual gear shift ratio even when one of the rotation speed sensor values is the first threshold value or greater, when a deceleration level of the drive wheel is a prescribed deceleration level or greater.Type: GrantFiled: July 27, 2017Date of Patent: August 18, 2020Assignees: JATCO LTD., NISSAN MOTOR CO., LTD.Inventors: Naoyasu Ikeda, Geunseok Ryu

Patent number: 9895958Abstract: A control device for a vehicle has a compressor for an air-conditioning device that is driven by a vehicle drive source, and a condenser for the air-conditioning device that is disposed at a front side of the vehicle. A request torque to the vehicle drive source is determined as a sum of an air-conditioning load which is spent for driving the compressor and a running torque necessary to drive the vehicle by a drive wheel. The running torque is calculated based on an accelerator manipulation of a driver. A range-position signal indicating a selected range position is read. A value of the air-conditioning load when the air-conditioning device is in operation and the range position is in a Reverse-range is larger than a value of the air-conditioning load when the range position is in a Drive-range with respect to an identical refrigerant pressure of the air-conditioning device.Type: GrantFiled: September 30, 2013Date of Patent: February 20, 2018Assignee: NISSAN MOTOR CO., LTD.Inventors: Naoyasu Ikeda, Ryosuke Ito
