Patent number: 11932770Abstract: A method for producing a resin sintered body 1 by applying an ink 3 to thermoplastic resin powder 2 and sintering the powder, the method including the step of immersing an intermediate resin sintered body 1m, which has an unevenly colored region on the surface thereof and the whole of which has been already sintered, in a surface treatment liquid containing sulfuric acid and chromic anhydride, in which the concentration of chromic anhydride is 300 g/L or more, for 5 minutes or longer. When producing a resin sintered body by sintering thermoplastic resin powder, the surface of the resin sintered body can be evenly and sufficiently colored to an extent required without an unevenly colored region on the surface thereof, and also the surface of the resin sintered body can have a good appearance and smoothness.Type: GrantFiled: March 14, 2022Date of Patent: March 19, 2024Assignees: SANKEI GIKEN KOGYO CO., LTD., HONDA MOTOR CO., LTD., SOLIZE CORPORATIONInventors: Daisuke Sato, Kazuo Igarashi, Hiroyuki Ikeno, Satoru Nishimoto, Takashi Inomata, Ryota Masuda, Kohei Mutai

Publication number: 20230302726Abstract: A method of manufacturing a resin formed product having a leather grain includes: a 3D printing step of inputting printing data to a 3D printer, and printing an intermediate product having an intermediate grain that is a base of the leather grain; and a post processing step of obtaining the resin formed product, which is a finished product, by carrying out post processing on the intermediate product printed in the 3D printing step. A grain height in input data, which is the printing data inputted in the 3D printing step, is greater than or equal to 120% of a stacking pitch in the 3D printing step.Type: ApplicationFiled: March 24, 2023Publication date: September 28, 2023Inventors: Ryota MASUDA, Kohei MUTAI, Hajime KAWAMURA, Hiroyuki IKENO, Kazuo IGARASHI, Satoru NISHIMOTO

Patent number: 9457769Abstract: A fin part (21e) is provided on a side opposite to a wiping surface side of a rubber holder (21) to press a blade rubber (22) toward the wiping surface side by receiving a wind (W) flowing along a moving car, and covering parts (23) protrude from both lengthwise ends of the blade rubber (22) toward the wiping surface side so as to partially cover lateral parts of the blade rubber (22). Owing to the fin part (21e), liftoff of a wiper blade (20) can be prevented. A wind (W) flowing from the front side to the rear side at an end part of a swing center side of the blade rubber (22) can be rectified by the covering part (23), and the wind (W) can flow along the rear side of the wiper blade (20) in the length direction of the wiper blade (20).Type: GrantFiled: November 30, 2011Date of Patent: October 4, 2016Assignees: Mitsuba Corporation, Honda Motor Co., Ltd.Inventors: Masaru Fujiwara, Kenichi Imoto, Ryu Ikezawa, Hiroyuki Sase, Kouji Okabe, Hisaaki Naruse, Hiroyuki Ikeno, Akira Takayama, Naomi Sase
