Publication number: 20240123979Abstract: An automatic brake control apparatus to be applied to a vehicle is configured to: detect, with an ultrasonic sensor, a position of an obstacle on reverse travel of the vehicle, in which the ultrasonic sensor is disposed in a rear part of the vehicle; set a brake operation area on plane coordinates corresponding to the detected position by the ultrasonic sensor; and actuate an automatic brake. The brake operation area includes a low-speed operation area and a high-speed operation area. The low-speed operation area is set on the reverse travel at a lower speed than a setting vehicle speed, and the high-speed operation area is set on the reverse travel at a higher speed than the setting vehicle speed. The high-speed operation area is wider than the low-speed operation area at least in a vehicle widthwise direction.Type: ApplicationFiled: December 28, 2023Publication date: April 18, 2024Inventors: Yuna AKIYAMA, Koichi MIZUTANI, Masayoshi KOIJI, Yusuke HAMADA, Kazuki MUTO, Tsubasa TAKASE

Patent number: 11390568Abstract: To provide a ceramic composite and a production method therefor allowing ease of processing to be improved and fracture toughness to be improved simultaneously. The invention includes the steps of: preparing at least a liquid-form resin and a ceramic sintered body which has been sintered at a temperature which is 700° C. to 100° C. less than a sintering temperature at which a theoretical density is obtained; immersing the ceramic sintered body in the liquid-form resin, causing the liquid-form resin to infiltrate the ceramic sintered body; and hardening the infiltrated liquid-form resin to obtain a ceramic composite having a relative density of between 40% and 90% by causing the resin to infiltrate. Gaps where no resin has infiltrated are formed in the ceramic composite.Type: GrantFiled: June 20, 2017Date of Patent: July 19, 2022Assignee: ADAMANT NAMIKI PRECISION JEWEL CO., LTD.Inventors: Hikaru Muto, Yusuke Akiyama, Shinichi Takeda, Shunsuke Karashima, Shunpei Amano

Patent number: 11357605Abstract: A ceramic body for dental prosthesis can suppress a variation in quality in the sole ceramic body for dental prosthesis due to expansion of its diameter. The ceramic body for dental prosthesis is made of a ceramic material, is shaped to have a circular planar shape and a disk-like external shape, and has a diameter of 50 mm or more. The method for manufacturing this ceramic body for dental prosthesis includes: preparing a ceramic material; shaping the ceramic material by press shaping or by a machine tool; temporarily sintering the ceramic material at a temperature from a sintering temperature that provides theoretical density ?700° C. or more to the sintering temperature ?100° C. or less; and shaping the ceramic material to have a circular planar shape and a disk-like external shape so as to prepare the ceramic body for dental prosthesis having a diameter of 50 mm or more.Type: GrantFiled: December 18, 2017Date of Patent: June 14, 2022Assignee: ADAMANT NAMIKI PRECISION JEWEL CO., LTD.Inventors: Yusuke Akiyama, Shinichi Takeda, Kazuyuki Syoji, Hideyuki Kanno
