Patent number: 11951933Abstract: In a lift-up buckle device, a worm wheel is engaged with a screw drive. When a worm is rotated in a forward direction and causes the screw drive to move downward, the worm moves the worm wheel downward. On the other hand, when the worm is rotated in a reverse direction and causes the screw drive to move upward, the worm moves the worm wheel upward. Consequently, the worm wheel may be stably engaged with the screw drive, and the worm wheel and worm may be stably mated.Type: GrantFiled: July 3, 2020Date of Patent: April 9, 2024Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Yusuke Watada, Shota Okuyama, Shigeki Yoshida

Publication number: 20200257074Abstract: Provided are a microscope apparatus capable of executing auto-focus control that appropriately follows a high-speed scan in a case of capturing a high-magnification and wide view image of an observation target contained in a container having large variations in the bottom surface, and a program. In a case where a microscope apparatus main body scans the bottom surface of the cultivation container by synchronously controlling a piezoelectric element and an actuator serving as optical axis-directional transport devices having different properties from each other, an objective lens of the imaging optical system is transported to a focus position in the optical axis direction.Type: ApplicationFiled: April 28, 2020Publication date: August 13, 2020Applicant: FUJIFILM CorporationInventor: Yusuke WATADA

Patent number: 10688957Abstract: In a lift-up buckle device, a slider and a shoe move forward and a buckle is moved to a stowed position. The shoe impacts against a protruding portion at a lower portion of a damper and interferes with a housing via the lower portion of the damper. Thus, the forward movement of the slider and shoe is stopped, while the damper absorbs an impact against the slider and shoe. Therefore, an amount of the impact against the slider and shoe that is absorbed by the damper may be increased by the protruding portion, and the damper may absorb the impact against the slider and shoe effectively.Type: GrantFiled: August 24, 2017Date of Patent: June 23, 2020Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Naoya Watanabe, Takuhiro Saito, Yasunori Hata, Makoto Matsuzaki, Yusuke Watada, Tatsuhiro Murasaki

Patent number: 10399538Abstract: In a buckle device, a pressing force, applied from wire ropes to an inside wall face of a wire guide groove of a wire guide, is along an imaginary line passing through a center of a cover plate first hole portion of a cover plate fixing tab of a cover plate and a center of a wire guide hole portion of the wire guide as viewed from the vehicle inside, similarly to a pressing force applied to a first fixing bolt that fixes the cover plate to a support plate, and these pressing forces are both oriented in the same direction. This enables rotation moment to be suppressed from occurring at the cover plate when the wire ropes are pulled toward their length direction leading end side.Type: GrantFiled: January 19, 2017Date of Patent: September 3, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Yasunori Hata, Takuhiro Saito, Tatsuhiro Murasaki, Yusuke Watada

Patent number: 10351095Abstract: A lift-up buckle device has a buckle with which is engaged a tongue through which a webbing, which is applied to a vehicle occupant, is inserted; wires that are made of metal, and whose longitudinal direction one end portions are fixed to the buckle, and that move together with the buckle; a driving portion that is connected to longitudinal direction other end portions of the wires, and that move the wires in a longitudinal direction; a wire guide that is made of metal and holds the wires in a curved state; a guide groove that is formed in the wire guide and in which the wires are inserted; and a resin member that is provided at an interior of the guide groove and abuts the wires.Type: GrantFiled: August 25, 2017Date of Patent: July 16, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Tatsuhiro Murasaki, Takuhiro Saito, Yasunori Hata, Yusuke Watada

Patent number: 10220811Abstract: A reduction in the durability of a coupling member coupled to a buckle is suppressed. A lift-up buckle device includes a buckle that engages with a tongue inserted through webbing worn by an occupant, and wires that each have a portion fixed to the buckle and that are displaced to move the buckle. The lift-up buckle device also includes a wire guide that includes a guide groove that guides the wires, and a soft lower cover that engages with the wire guide and covers the wires. A dimension of an end portion on the buckle side of the guide groove is set so as to increase on progression toward the buckle side.Type: GrantFiled: January 19, 2017Date of Patent: March 5, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Tatsuhiro Murasaki, Takuhiro Saito, Yasunori Hata, Yusuke Watada, Koji Hayashi, Makoto Matsuzaki

Patent number: 10124760Abstract: Load input to an occupant from a buckle is reduced. A lift-up buckle device includes a buckle that engages with a tongue inserted through webbing worn by an occupant. The lift-up buckle device also includes wires that each include a portion configuring a first fixed portion fixed to the buckle side and another portion configuring a supported portion supported by a wire guide, and that move the buckle due to a distance between the fixed portions and the supported portions being changed. Respective locations between the fixed portions and the supported portions of the wires are displaced in a direction intersecting an engaged direction of the tongue when an external force in a direction of the engaged direction of the tongue has been input to the buckle.Type: GrantFiled: January 19, 2017Date of Patent: November 13, 2018Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Yusuke Watada, Takuhiro Saito, Yasunori Hata, Tatsuhiro Murasaki

Publication number: 20180056930Abstract: In a lift-up buckle device, a slider and a shoe are provided at a seatbelt device. The slider and the shoe are moved by a drive screw that is driven by an output shaft of a motor. Here, a buffering body is provided at the output shaft, and concave portions are formed at corner portions of an inserted-into portion. Therefore, projecting portions which project-out into the inserted-into portion being formed at the corner portions of the inserted-into portion when the buffering body is molded can be suppressed, and corner portions of the output shaft interfering with the projecting portions can be suppressed. Accordingly, because rattling of the output shaft within the inserted-into portion can be suppressed, operating noise can be reduced.Type: ApplicationFiled: August 25, 2017Publication date: March 1, 2018Inventors: Tatsuhiro MURASAKI, Takuhiro SAITO, Yasunori HATA, Yusuke WATADA
