Patent number: 9460607Abstract: The present technology provides a system for detecting the tensile force of a guy rope in a pneumatic fender capable of preventing the breakage of the guy rope, and a pneumatic fender. Tensile force data detected by a tensile force sensor detecting the tensile force of a guy rope is transmitted by a wireless transmitter, and is inputted to a computation device through a receiver. An alerting device issues an alert when the tensile data is at least equivalent to reference data previously inputted to the computation device.Type: GrantFiled: December 16, 2013Date of Patent: October 4, 2016Assignee: The Yokohama Rubber Co., LTD.Inventors: Shigeki Sakakibara, Michito Kaneko, Shu Yamada, Minami Izumi, Koji Nakatani

Patent number: 9428875Abstract: Provided is a pneumatic fender that suppresses damage to a flexible hollow body and an energy-absorbing body and exhibits improved ship sway reduction effects. A pneumatic fender is provided with an orifice that allows for communication between an interior space of a flexible hollow body and the interior space of the casing, and a safety valve that opens and allows for communication between the internal space of the flexible hollow body and the internal space of the casing by opening when the internal pressure of the flexible hollow body reaches a predetermined pressure.Type: GrantFiled: October 11, 2013Date of Patent: August 30, 2016Assignee: The Yokohama Rubber Co., LTD.Inventors: Minami Izumi, Shigeki Sakakibara, Michito Kaneko, Shu Yamada, Yoshiaki Hara, Akihiro Iemoto

Patent number: 9422040Abstract: A computer 11 of a ship monitoring device 1 arranges one kind of transmission data between two consecutive start control codes and two consecutive termination control codes. The computer 11 also arranges information indicating a type of the transmission data between the transmission data and the start control codes and between the termination control codes and the transmission data. In this way, the transmission data is transmitted in form of packet data. Therefore, transmission data in information communication between ships and sensed information in information communication of fenders can be easily distinguished from each other. In addition, a type of information transmitted as the transmission data can be easily identified.Type: GrantFiled: July 22, 2013Date of Patent: August 23, 2016Assignee: THE YOKOHAMA RUBBER CO., LTD.Inventors: Kazunori Ono, Masahiko Miyamoto, Koji Nakatani, Shu Yamada, Shigeki Sakakibara, Minami Izumi, Michito Kaneko

Patent number: 9365992Abstract: A pneumatic fender having a body portion is configured by laminating a plurality of reinforcing layers between the inner layer rubber and the outer layer rubber. Cords of reinforcing layers are laminated adjacent to each other. The cords intersect and are arranged at a predetermined cord angle with respect to the body axial direction. An intermediate rubber layer is interposed between each of the reinforcing layers. In an uninflated, neutral state, the thicknesses of the intermediate rubber layers are 1 mm to 5 mm, and the cord angle is set from 15° to 45°, so when the interior of the fender is filled with air to the prescribed internal pressure, the cord angle increases to a static angle while the intermediate rubber layers deform in shear, and the body portion increases in diameter and inflates.Type: GrantFiled: April 24, 2013Date of Patent: June 14, 2016Assignee: The Yokohama Rubber Co., LTD.Inventors: Shu Yamada, Shigeki Sakakibara, Michito Kaneko, Minami Izumi

Patent number: 9334029Abstract: A position of a target ship alongside is displayed in animation on a display unit 17 by the computer 11 based on any one of the positional information on the target ship alongside, which is transmitted from an automatic identification system (AIS) of a target ship alongside and is obtained by an AIS communication unit 13, positional information on the target ship alongside, which is obtained by the GNSS communication unit 14 from a global navigation satellite system, and positional information on the target ship alongside, which is manually inputted via an operation unit 18. Therefore, the latest position of the target ship alongside can be always displayed in animation.Type: GrantFiled: July 22, 2013Date of Patent: May 10, 2016Assignee: THE YOKOHAMA RUBBER CO., LTD.Inventors: Masahiko Miyamoto, Shu Yamada, Shigeki Sakakibara, Kazunori Ono, Koji Nakatani, Michito Kaneko
