Publication number: 20240172359Abstract: Provided is a roughened copper foil capable of achieving both excellent transmission characteristics and high peel strength when used for a copper-clad laminate or a printed wiring board. This roughened copper foil includes a roughened surface on at least one side. The roughened surface has a roughness slope tan ? of 0.58 or less as calculated based on a mean height Rc (?m) and a mean width RSm (?m) of profile elements by formula Rc/(0.5×RSm), and a small projected area Rc×RSm of 0.45 ?m2 or more and 2.00 ?m2 or less that is a product of the mean height Rc (?m) and the mean width RSm (?m) of the profile elements. Rc and RSm are values measured in accordance with JIS B0601-2013 under a condition of not performing a cutoff by a cutoff value ?s and a cutoff value ?c.Type: ApplicationFiled: March 17, 2022Publication date: May 23, 2024Applicant: MITSUI MINING & SMELTING CO., LTD.Inventors: Ayumu TATEOKA, Ryosuke KANEYAMA, Yasuji HARA, Yasuo SATO, Shinichi OBATA, Chun Chieh LI

Publication number: 20230264798Abstract: A propulsion device for a marine vessel includes an engine and a forward/reverse shifting mechanism. The direction of a propulsive force generated by the propulsion device is changed according to a shift position of the forward/reverse shifting mechanism. The shift position is changeable between a forward position and a reverse position via a neutral position. In response to a command signal based on an operation of a joystick or an operator, the shift position of the forward/reverse shifting mechanism and the engine are controlled. When the shift position of the forward/reverse shifting mechanism is changed from the neutral position to a position corresponding to a direction opposite to a travelling direction of the marine vessel, which is determined based on the speed of the marine vessel, a correction control is performed to increase an output of the engine based on the speed of the marine vessel.Type: ApplicationFiled: January 10, 2023Publication date: August 24, 2023Inventors: Ryosuke HARA, Hiroki SATO
