Patent number: 11460478Abstract: In a first transfer station, a second transfer station, and a third transfer station, a plurality of sample containers are transferred while being stored from a transfer source rack to a transfer destination rack row. In this case, for each of the sample containers to be a transfer target, a specific transfer destination rack is selected from the transfer destination rack row based on a content of processing to be applied in the future to a sample within the sample container.Type: GrantFiled: February 4, 2020Date of Patent: October 4, 2022Assignees: Hitachi, Ltd., Hitachi Industrial Equipment Systems Co., Ltd.Inventors: Kenta Sugiyama, Shigeki Okuno, Kunihiro Fujiki, Yoshinori Takeyama, Hidehiko Fushimi, Hideaki Kataho

Patent number: 11407151Abstract: A vehicular resin molded article is formed by solidifying a molten resin filled in a cavity of an injection mold and having a concave gate mark formed by a valve pin and remaining thereon in which L/T is 190 or more where L is a flow distance of the molten resin from the gate mark to a filling terminal and T is a maximum thickness. When the valve pin is moved to the cavity side and is pressed against the molten resin, since the contact area of a tip end portion with respect to the molten resin in the vehicular resin molded article increases and the temperature of the tip end portion in the valve pin tends to decrease, the portion of the vehicular resin molded article where the valve pin is pressed against is sufficiently solidified and string drawing or silver streak is less likely to occur.Type: GrantFiled: December 20, 2019Date of Patent: August 9, 2022Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Kenta Sugiyama, Masashi Katayama, Yuichi Ikeya, Hiroyoshi Oi

Patent number: 10697610Abstract: A resin molded product produced by injection molding includes: a gate mark formed on a non-design surface; and a step provided so as to intersect with a flow of a resin injected from a gate. When a flow distance of the resin from the gate mark to an end portion of the resin molded product is L [mm], and a thickness of the resin molded product is t [mm], the resin molded product is configured to have L/t of 185 or more, and a tangential angle of the step is 5° to 30°.Type: GrantFiled: January 30, 2019Date of Patent: June 30, 2020Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Kenta Sugiyama, Masashi Katayama, Eiji Matsubara

Patent number: 10648634Abstract: A two-color molded lens includes: a lens body portion and a lens peripheral wall portion that rises toward an inner surface side of the two-color molded lens from a peripheral edge portion of the lens peripheral wall portion. The two-color molded lens is provided with a hard coating film on an outer surface thereof and an anti-fogging coating film on the inner surface thereof. The primary molded product is formed to wrap around from the lens body portion, the secondary molded product is formed to wrap around from the lens peripheral wall portion, a joining surface between the primary molded product and the secondary molded product is positioned on the lens body portion, and a corner R is set to a value of R0.2 mm or less in the primary molded product.Type: GrantFiled: November 5, 2018Date of Patent: May 12, 2020Assignee: Koito Manufacturing Co., Ltd.Inventors: Keisuke Mizutani, Kenta Sugiyama
