Publication number: 20240123464Abstract: A coating nozzle is provided. The coating nozzle includes: a chamber portion, communicated with a coating material supply portion; a supply surface, disposed on a side of the chamber portion; a discharge surface, disposed on other side of the chamber portion opposite to the supply surface and used to discharge the coating material; supply holes, annularly arranged on the supply surface with a first position as a center; discharge holes, arranged into at least one straight line on the discharge surface; and communication hole paths, respectively and correspondingly communicated from the supply holes on the supply surface to the discharge holes on the discharge surface. The communicating holes respectively have different lengths. The communication hole paths include a large diameter portion and a small diameter portion whose diameter is shorter that of the large diameter portion. The small diameter portions respectively have different diameters or lengths.Type: ApplicationFiled: July 26, 2023Publication date: April 18, 2024Applicant: Honda Motor Co., Ltd.Inventors: Gaku KAWABE, Naoki ETO

Publication number: 20240105225Abstract: A controller of a magnetic disk device obtains, for each of a plurality of first position sets, a first distribution that is a radial distribution of differences between a target orbit of the magnetic head and an actual position of the magnetic head while correcting a disturbance synchronized with rotation of the magnetic disk by using correction amounts at a plurality of positions included in one of the plurality of first position sets. The controller performs weighting the first distribution according to a position in the radial direction and calculating an evaluation value based on the weighted first distribution for each of the plurality of first position sets. The controller selects a second position set from the plurality of first position sets based on the evaluation value. The controller records correction amounts at a plurality of positions included in the second position set by the magnetic head.Type: ApplicationFiled: March 8, 2023Publication date: March 28, 2024Inventors: Sho SUZUKI, Takayuki KAWABE, Takeyori HARA, Naoki TAGAMI

Patent number: 10619407Abstract: A sliding fire door is disclosed with an improved tightness of the closure by the door main body. The sliding fire door includes an opening frame, a fire door, and a guiding mechanism. The guiding mechanism includes a guide roller group which includes a plurality of guide rollers arranged one adjacent to another along the slide direction and which is configured to guide the door main body. The guiding mechanism is configured to guide the door main body such that the door main body is moved from an opening position to a closing position. The door main body has a first opposing surface which is oriented toward the wall. The opening frame has a second opposing surface which is oriented toward the first opposing surface of the door main body in the closing position. The guiding mechanism moves the door main body to cause the first opposing surface to be moved closer to the second opposing surface when the door main body is moved from the opening position to the closing position.Type: GrantFiled: May 30, 2018Date of Patent: April 14, 2020Assignee: Daifuku Co., Ltd.Inventors: Naoki Kawabe, Nobuo Ogawa, Yoshihiro Hosaka, Takafumi Yamazaki
