Publication number: 20230233913Abstract: A bat includes a handle having a proximate end and a distal end, a barrel having a hollow portion that accommodates the distal end, and a first damping section at least partially sandwiched between the handle and the barrel in the interior of the hollow portion. The first damping section includes a first portion in contact with each of the handle and the barrel in the interior of the hollow portion, and a second portion disposed closer to the proximate end than the first portion, the second portion being in contact with an inner peripheral surface of the barrel and not being in contact with an outer peripheral surface of the handle. In a cross section along a center axis of the barrel, the barrel has a depression depressed relative to the inner peripheral surface in the cross section, the second portion has a protrusion fitted in the depression.Type: ApplicationFiled: January 27, 2022Publication date: July 27, 2023Inventors: Yohei Yamashita, Katsuhisa Hirano, Thu Van Nguyen, Chi-Hung Lee, Renqin Zhang

Publication number: 20230113166Abstract: A bat, which has a hollow barrel and an internal assembly configured to resist deformation of the hollow barrel, is disclosed. The internal assembly includes a rod disposed longitudinally in the hollow barrel, a ring attached to the rod, a deformable sleeve disposed around the ring and extending longitudinally in the hollow barrel. The sleeve can include an outer diameter smaller than an inner diameter of the hollow barrel. The bat can include an end cap attached to an end of the hollow barrel and having a recess configured to receive an end of the rod. The rod can be configured to maintain the deformable sleeve in a predetermined suspended position within the hollow barrel such that, when the bat is at rest, the sleeve is disposed a predetermined gap distance from an inner surface of the hollow barrel.Type: ApplicationFiled: December 12, 2022Publication date: April 13, 2023Inventors: Kohei Kikuchi, Yohei Yamashita, David Llewellyn, Thu Van Nguyen, Chi-Hung Lee, Renqin Zhang, Katsuhisa Hirano

Patent number: 11459039Abstract: A vehicular under cover includes an oblong hole-shaped through-hole and is assembled to a lower side of a vehicle so as to cover a lower part of the heat source. In a plan view, the through-hole is formed so that a longitudinal direction of the through-hole is inclined with respect to a front-rear direction of the vehicle. The inclination excludes an orthogonal direction to the front-rear direction of the vehicle.Type: GrantFiled: November 15, 2019Date of Patent: October 4, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kazuya Matsushita, Katsuhisa Hirano, Hiromichi Sato, Go Kuroyanagi, Yuya Chono, Hisashi Jufuku

Patent number: 11389703Abstract: A bat includes a ball hitting portion. The ball hitting portion includes a plurality of fiber-reinforced resin layers stacked in a radial direction relative to a center axis of the ball hitting portion. The plurality of fiber-reinforced resin layers include a first fiber-reinforced resin layer disposed at an outermost circumference in the radial direction among the plurality of fiber-reinforced resin layers. The first fiber-reinforced resin layer has a plurality of first fiber bundles and a plurality of second fiber bundles. The plurality of first fiber bundles are disposed side by side in a short side direction of each of the plurality of first fiber bundles. The plurality of second fiber bundles are disposed side by side in a short side direction of each of the plurality of second fiber bundles. The plurality of first fiber bundles and the plurality of second fiber bundles are woven across one another.Type: GrantFiled: December 9, 2019Date of Patent: July 19, 2022Assignee: Mizuno CorporationInventors: Yohei Yamashita, Katsuhisa Hirano

Patent number: 7481484Abstract: A pedestrian protection apparatus for a vehicle including a plate member which is disposed at a lower part of a front of the vehicle so as to extend in a frontward and backward direction of the vehicle. The plate member has a concave portion which is open at the upper surface of the plate member and which is formed in the plate member so as to be positioned more frontward of the vehicle than a radiator. The concave portion includes a non-horizontal bottom portion which provides a non-horizontal inner surface extending in an inclined or curved manner such that a depth thereof is gradually increased toward a rear side of the vehicle, and an outlet hole which is disposed at the concave portion so as to be positioned more rearward of the vehicle than the non-horizontal inner surface.Type: GrantFiled: December 3, 2007Date of Patent: January 27, 2009Assignee: Kojima Press Industry Co., Ltd.Inventor: Katsuhisa Hirano
