Patent number: 10513421Abstract: The present disclosure presents a webbing take-up device, which comprises: a spool; a lock section that is restricted from rotating at a time of a vehicle emergency so as to limit rotation of the spool in the pull-out direction; a force limiter mechanism that permits rotation of the spool in the pull-out direction at a force limiter load or greater when rotation of the spool in the pull-out direction with respect to the lock section is being limited; a switching member that switches a load value of the force limiter load by switching between a rotation-restricted state and a rotation-enabled state; and a mounting member that includes a switching member mounting section at which the switching member is disposed, and a restriction section that is engaged with the switching member so as to restrict displacement of the switching member disposed at the switching member mounting section.Type: GrantFiled: July 28, 2017Date of Patent: December 24, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Yoshihiko Ushiyama, Masaru Ukita, Kaoru Yuasa, Kosuke Miida

Patent number: 10479318Abstract: A webbing pull-in device has a take-up shaft at which a webbing can be pulled in due to the take-up shaft being operated, a first pulley that is rotated at a time of an emergency of a vehicle, and a second pulley that, by being rotated, operates the take-up shaft. Further, the webbing pull-in device has a connecting wire that connects the first pulley and the second pulley, and that, by being taken up onto the first pulley at a time when the first pulley is rotated, transmits rotational force of the first pulley to the second pulley.Type: GrantFiled: May 11, 2016Date of Patent: November 19, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Haruhiko Hashimoto, Masaru Ukita, Ryu Nakashima, Yoshihiko Ushiyama

Patent number: 8668951Abstract: A liquid material arrangement method is a method for arranging a liquid material in a plurality of prescribed regions on a substrate by discharging the liquid material as a droplet from a nozzle. The liquid material arrangement method includes: performing a discharge information acquiring step for acquiring discharge information of the nozzle including a landing position and a discharge quantity of the droplet discharged from the nozzle by a nozzle check; performing a second pattern generating step for generating a second dot pattern, which is an arrangement pattern for arranging a prescribed number of droplets, by selecting at least one non-discharge dot from a first dot pattern, which is an arrangement pattern for arranging more droplets than the prescribed number of droplets, based on the discharge information; and performing a liquid material arranging step for arranging the liquid material in the prescribed regions based on the second dot pattern.Type: GrantFiled: March 13, 2012Date of Patent: March 11, 2014Assignee: Seiko Epson CorporationInventors: Yoshihiko Ushiyama, Tsuyoshi Kitahara, Yoichi Miyasaka

Patent number: 8389046Abstract: A liquid material arrangement method includes a first patter generating step, a dot deleting step and a liquid material arranging step. In the first pattern generating step, a first dot pattern is generated in which a first prescribed number of dots is set. In the dot deleting step, a second prescribed number of dots is deleted to generate a second dot pattern. In the liquid material arranging step, a liquid material is arranged in the prescribed region on the substrate by causing a nozzle and the substrate to scan in relative manner and discharging the liquid material based on the second dot pattern. In the dot deleting step, a dot indicator for each the first prescribed number of dots is determined based on discharge information of the nozzle, and the second prescribed number of dots is deleted based on the dot indicator.Type: GrantFiled: October 2, 2007Date of Patent: March 5, 2013Assignee: Seiko Epson CorporationInventors: Yoshihiko Ushiyama, Tsuyoshi Kitahara, Yoichi Miyasaka

Patent number: 8247021Abstract: A liquid material arrangement method includes performing a first pattern generating step, a dot deleting step, and a liquid material arranging step. The first pattern generating step includes generating a first dot pattern in which a first prescribed number of dots is set according to the prescribed region. The dot deleting step includes deleting a second prescribed number of dots from the first prescribed number of dots to generate a second dot pattern. The liquid material arranging step includes arranging a liquid material in a prescribed region on a substrate by causing a nozzle and the substrate to scan in relative manner and discharging the liquid material from the nozzle based on the second dot pattern. The performing of the dot deleting step further includes deleting at least one prohibited dot with priority with the prohibited dot being determined based on discharge information of the nozzle determined in advance.Type: GrantFiled: August 7, 2007Date of Patent: August 21, 2012Assignee: Seiko Epson CorporationInventors: Yoshihiko Ushiyama, Tsuyoshi Kitahara, Yoichi Miyasaka
