Patent number: 11940047Abstract: To provide a simple-structured chain guide assembly frame capable of reliably maintaining a correct positional relationship between a driven sprocket and a sprocket holding portion without the possibility of driven sprocket detachment. The chain guide assembly frame includes a main body having a fixed-guide-side sprocket holding portion and a pivoting-guide-side sprocket holding portion. The fixed-guide-side sprocket holding portion includes a first fixed-guide-side support portion that supports a driven sprocket at a first contact point, and a second fixed-guide-side support portion that supports the driven sprocket at a second contact point located more outside than the first contact point. When the driven sprocket is in an erected state in which the driven sprocket is supported at the first contact point and second contact point, the vector of gravity acting on the gravity center of the driven sprocket points between the first contact point and second contact point.Type: GrantFiled: December 13, 2022Date of Patent: March 26, 2024Assignee: TSUBAKIMOTO CHAIN CO.Inventors: Volkmar Nyga, Seigo Ohsawa, Sung-Hwan Lim, Munehiro Maeda, Yuji Oshima

Patent number: 11933400Abstract: To provide a chain guide assembly frame capable of efficiently collecting the oil that adhered to various parts of the chain guide assembly, and guiding the collected oil to predetermined locations, to allow efficient use of oil, with a simple structure. The chain guide assembly frame includes driven sprocket holding portions, a fixed chain guide, and a pivoting chain guide holding portion on a main body. A drive sprocket holding portion is provided at a position lower than the driven sprocket holding portions. The main body includes a concave and/or convex oil passage that extends from an upper part toward a lower part to guide the oil toward above the drive sprocket holding portion.Type: GrantFiled: December 13, 2022Date of Patent: March 19, 2024Assignee: TSUBAKIMOTO CHAIN CO.Inventors: Volkmar Nyga, Seigo Ohsawa, Sung-Hwan Lim, Munehiro Maeda, Yuji Oshima

Publication number: 20230304565Abstract: To provide a chain guide, chain drive device, and transmission system, with which an amount of lubricating oil supplied to guide surfaces is increased. The chain guide includes an upper additional extension formed to extend from an upper end of a sliding guide part in the guide longitudinal direction and having an oil-recovery guide surface positioned opposite and spaced from the chain.Type: ApplicationFiled: March 21, 2023Publication date: September 28, 2023Applicant: TSUBAKIMOTO CHAIN CO.Inventors: Sung-Hwan LIM, Munehiro MAEDA, Seigo OHSAWA, Yuji OSHIMA

Patent number: 11732785Abstract: An object of the present invention is to provide a chain guide mechanism that can readily integrate all the components in a simple structure and enhance work efficiency during assembly or maintenance. The chain guide mechanism of the present invention is configured to be able to integrally support, on a frame, components including a plurality of sprockets, a chain, a fixed chain guide, and a pivoting chain guide. The frame includes a pivoting chain guide holding part that holds a mounting boss of the pivoting chain guide in a state of a loose fit. The pivoting chain guide holding part is configured to allow the mounting boss to be fitted therethrough from one side.Type: GrantFiled: November 5, 2021Date of Patent: August 22, 2023Assignee: TSUBAKIMOTO CHAIN CO.Inventors: Volkmar Nyga, Seigo Ohsawa, Munehiro Maeda, Yuji Oshima

Patent number: 11010216Abstract: An RPC conversion processing system (10) that performs relaying between a first application (70) and second application (80) of different protocols. The RPC conversion processing system includes a first interface provider (20) connected to the first application and configured to provide a first interface for the first application, an RPC conversion relay function section (40), and a second interface provider (30) connected to the second application and configured to provide a second interface for the second application. The first interface provider receives a request for processing an RPC from the first application. The RPC conversion relay function section converts the RPC into an RPC of the second application and outputs the RPC of the second application to the second interface provider, thereby relaying an RPC between the first application and the second application.Type: GrantFiled: December 13, 2017Date of Patent: May 18, 2021Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Tomoyuki Fujino, Yuji Oshima, Keiichiro Kashiwagi, Hisaharu Ishii, Yui Yoshida

Patent number: 10459073Abstract: If the boundary value of a velocity scale set in a case where the information indicating the velocity of the moving body is displayed on a liquid crystal panel is less than a threshold value, the frequency of pulses used in pulse-width control is set to 20 kHz in such a manner that noise ascribable to the pulses for pulse-width control will not be displayed on the liquid crystal panel. If the boundary value of the velocity scale is equal to or greater than the threshold value, then the frequency of pulses used in pulse-width control is set to 200 Hz in such a manner that noise ascribable to the pulses for pulse-width control will reside at a position remote from the information indicative of velocity.Type: GrantFiled: February 8, 2016Date of Patent: October 29, 2019Assignee: FUJIFILM CorporationInventors: Yuji Oshima, Yukiya Miyachi
