Patent number: 12147171Abstract: A developing cartridge includes: a casing, a developing roller, a first agitator, a supply roller, and a second agitator. The casing is configured to accommodate toner. The developing roller is rotatable about a developing roller rotation axis extending in a first direction. The first agitator is configured to agitate the toner. The first agitator is rotatable about a first agitator rotation axis extending in the first direction. The supply roller is positioned between the first agitator and the developing roller. The supply roller is rotatable about a supply roller rotation axis extending in the first direction. The second agitator is positioned between the supply roller and the first agitator. The second agitator is rotatable about a second agitator rotation axis extending in the first direction. A rotation locus of the second agitator is positioned outside of a rotation locus of the first agitator.Type: GrantFiled: December 12, 2022Date of Patent: November 19, 2024Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Kazuaki Ooka, Junichi Hashimoto, Shota Iriyama, Keigo Nakajima, Kengo Yada

Patent number: 12109718Abstract: A razor head includes a frame, elongated blades arranged on an inner side of the frame, and two bridge walls each extending between two points of the frame in an interior of the frame, the bridge walls each including projections arranged in an arrangement direction of the blades. Each of the blades is held between adjacent ones of the projections of the bridge walls. Each of the projections includes a first flat surface and a second flat surface. In each of the bridge walls, the first flat surface and the second flat surface are shifted from each other in a longitudinal direction of the blades so as not to overlap each other, and the first flat surfaces and the second flat surfaces are located on the same position as viewed in the arrangement direction. Each of the projections has a horizontal cross-sectional shape of a parallelogram.Type: GrantFiled: September 10, 2019Date of Patent: October 8, 2024Assignee: KAI R&D CENTER CO., LTD.Inventor: Kengo Hashimoto

Publication number: 20220314475Abstract: A razor head includes a frame including two opposing long side walls and two opposing short side walls, connectors each connecting two points of the frame in an interior of the frame, and elongated blades arranged on an inner side of the frame. The blades are coupled to only two of the connectors, the two connectors to which the blades are coupled connecting the two long side walls to each other. In a case where a position in the frame in a longitudinal direction is represented by a percentage, when a middle of the frame in the longitudinal direction is 0% and two ends of the frame in the longitudinal direction that correspond to inner surfaces of the two short side walls are 100%, the two connectors to which the blades are coupled are each arranged in a range from 30% to 90% between the middle and the two ends.Type: ApplicationFiled: September 10, 2019Publication date: October 6, 2022Applicant: KAI R&D CENTER CO., LTD.Inventor: Kengo Hashimoto

Patent number: 11247358Abstract: A pivotal neck type razor includes a holder having a top end, and a razor head attached to the holder. The razor head includes a blade assembly, an elastic support body, and a connection unit that is continuous with the top end of the holder. The elastic support body includes a support portion that supports the blade assembly and a flexible portion located between the support portion and the connection unit. The blade assembly is urged by the flexible portion of the elastic support body to be stationary at a neutral position. The blade assembly is movable to at least one movement position from the neutral position against an urging force of the flexible portion.Type: GrantFiled: July 24, 2018Date of Patent: February 15, 2022Assignee: KAI R&D CENTER CO., LTD.Inventor: Kengo Hashimoto

Patent number: 10335970Abstract: A razor blade cartridge is detachably attached to a holder. A socket portion is provided to the holder. A coupler projection, which detachably attaches to the socket portion through the insertion/ejection opening of the socket portion, is provided to the blade cartridge. A guide portion, which extends towards the opposite side from the skin contacting surface of the blade cartridge and is supported by the socket portion of the holder, is provided to the coupler projection of the blade cartridge. The end of the guide portion is provided with a manipulation portion, which is manipulated at the manipulation opening of the socket portion to release the guide portion from the socket portion and the manipulation of which removes the blade cartridge from the insertion/ejection opening of the socket portion. Thus, the blade cartridge can be easily removed by a gentle application of pressure on the manipulation portion.Type: GrantFiled: October 8, 2014Date of Patent: July 2, 2019Assignee: KAI R&D CENTER CO., LTD.Inventor: Kengo Hashimoto

Publication number: 20160004110Abstract: A liquid crystal panel includes a first board, a second board, a sealing member, a first inner limiting portion, and a first outer limiting portion. The second board is disposed opposite the first board with internal space therebetween. The sealing member is disposed between the first and the second boards so as to surround and seal the internal space. The inner limiting portion is included in at least one of the first and the second boards and located closer to the internal space than the sealing member for limiting a forming area of the sealing member from an internal space side. The outer limiting portion is included in at least one of the first and the second boards and located on an outer side farther from the internal space than the sealing member for limiting the forming area of the sealing member from the outer side.Type: ApplicationFiled: February 20, 2014Publication date: January 7, 2016Applicant: Sharp Kabushiki KaishaInventors: Akihiro IMAI, Masaki ITO, Masao YAMAGUCHI, Yosuke MORI, Kengo HASHIMOTO, Makoto KANBE
