Publication number: 20240142275Abstract: A position detection device configured to detect a position of a moving member that moves back and forth in a predetermined moving direction is provided with an exciting coil arranged to extend in the moving direction along the moving member, a detection coil that, by a magnetic field generated by the exciting coil, outputs a voltage corresponding to a position of a detection object portion moving together with the moving member within a predetermined detection range in the moving direction, and a calculation unit that determines the position of the moving member by calculation based on an output voltage of the detection coil. The detection object portion has a predetermined length in the moving direction, and a voltage is generated in the detection coil due to a difference in magnetic field intensity between a portion corresponding to the detection object portion and a portion not corresponding to the detection object portion.Type: ApplicationFiled: October 17, 2023Publication date: May 2, 2024Inventors: Yohei SHIRAKAWA, Yuta SUGIYAMA, Yoshiaki YANAGISAWA, Yoshitake AGEISHI, Yukio IKEDA

Publication number: 20240142277Abstract: A position detection device detects a position of a moving member moving backward and forward in a predetermined moving direction. The position detection device includes an exciting coil disposed along the moving member and extending in the moving direction, a detection coil that outputs a voltage corresponding to a position of a detection target portion moving with the moving member by means of a magnetic field generated by the exciting coil within a predetermined detection range in the moving direction, and a calculation unit that calculates the position of the moving member by the output voltage of the detection coil. The detection coil includes a pair of coil elements whose output voltage changes according to the position of the moving member, and phases of the output voltages of the pair of coil elements during movement of the moving member within the detection range differ from each other.Type: ApplicationFiled: October 20, 2023Publication date: May 2, 2024Inventors: Yohei SHIRAKAWA, Yuta SUGIYAMA, Yoshiaki YANAGISAWA, Yoshitake AGEISHI, Yukio IKEDA

Publication number: 20230243326Abstract: A method for manufacturing a coupling body includes a press-fitting step of press-fitting a coupling shaft-shaped portion of a valve member into a pit portion of a cap. A peripheral surface of a high-hardness component having a relatively high hardness of an outer peripheral surface of the coupling shaft-shaped portion of the valve member and an inner peripheral surface of the pit portion of the cap includes: a first-stage cylindrical surface having a diameter difference with respect to a peripheral surface of a low-hardness component; and a second-stage cylindrical surface positioned closer to a rear side in a press-fitting direction than the first-stage cylindrical outer peripheral surface and protruding in a radial direction to form a step with respect to the first-stage cylindrical surface.Type: ApplicationFiled: May 18, 2021Publication date: August 3, 2023Inventors: Ryohei MATSUTAKE, Kenichi GUNJI, Yuta YANAGISAWA, Masato HIGUMA

Publication number: 20230156295Abstract: A video distribution system according to this disclosure is a video distribution system that distributes a video including an animation of a character object generated based on a movement of a distribution user and comprises one or a plurality of computer processors. The one or plurality of computer processors provide (i) a distribution portion, (ii) a display device, (iii) a determination portion. If the determination portion determines that a first object is being displayed within a predetermined distance from a second object, the object display device changes the first object and the second object to a third object and displays the third object.Type: ApplicationFiled: January 18, 2023Publication date: May 18, 2023Applicant: GREE, INC.Inventors: Soichiro TAKAKUWA, Yuta YANAGISAWA, Aya KURABUCHI

Publication number: 20220275779Abstract: An object of the present invention is to provide a working method of an orifice, which has excellent working accuracy and high productivity in order to work an inclination portion (tapered portion) on the entire circumference of an inner wall of an orifice. Therefore, a working method of an orifice includes a first step of forming an orifice hole 54d in an orifice forming member, a second step of pressing a downstream end surface of the orifice forming member in which the orifice hole 54d opens, in a direction toward an upstream side of the orifice hole 54d by a punch 46 having a cutting blade portion 46a larger than a cross section of the orifice hole 54d. The second step causes a material of the orifice forming member to flow from an entire circumference at the downstream end portion of the orifice hole 54d to an inside of the orifice hole 54d to form a cross-sectional area reduction portion 54s in which a cross-sectional area of the orifice hole 54d is reduced from an upstream side to a downstream side.Type: ApplicationFiled: March 27, 2020Publication date: September 1, 2022Inventors: Kenichi GUNJI, Masato HIGUMA, Ryohei MATSUTAKE, Yuta YANAGISAWA, Yuki SUGIYAMA

Patent number: 10190555Abstract: It is important not to form the partial bump in the collision structural part, however the fixed core and the movable core are relatively inclined due to an accumulation of tolerances and therefore even if each collision structural part of the fixed core and the movable core in formed in a flat shape, the fixed core and the movable core are contacted with not the whole of the collision structural parts but a part of the collision structural parts at the moment of the collision. In a case in which the collision structural part is formed in a ring shape or an intermittent ring shape, the fixed core and the movable core are contacted with each other at outer peripheral parts. Thus, when the fixed core and the movable core are collided with each other, a high stress is applied to the outer peripheral parts contacted first.Type: GrantFiled: January 16, 2015Date of Patent: January 29, 2019Assignee: Hitachi Automotive Systems, Ltd.Inventors: Atsushi Takaoku, Yuta Yanagisawa, Kiyotaka Ogura
