Publication number: 20240131832Abstract: Provided is a method for manufacturing a laminate that is excellent in adhesion between the copper foil and the resin film while using a polyvinyl acetal resin having low reactivity with the copper foil. This method includes the steps of providing a copper foil having on at least one side a treated surface on which an amount of metal components is 30 atomic % or more and 40 atomic % or less, and attaching or forming a polyvinyl acetal resin film on the treated surface of the copper foil to form a laminate. The amount of metal components is a proportion of Cr, Ni, Cu, Zn, Mo, Co, W, and Fe in a total amount of N, O, Si, P, S, Cl, Cr, Ni, Cu, Zn, Mo, Co, W, and Fe when the treated surface is subjected to elemental analysis by X-ray photoelectron spectroscopy (XPS).Type: ApplicationFiled: February 8, 2022Publication date: April 25, 2024Applicant: MITSUI MINING & SMELTING CO., LTD.Inventors: Hiroto IIDA, Makoto HOSOKAWA, Misato MIZOGUCHI, Shinya HIRAOKA, Toshiyuki SHIMIZU

Patent number: 9689660Abstract: An object of this invention is to sense a transient displacement of the blade position to thereby detect abnormalities early. The invention includes: one or more first sensors mounted so as to be removable from an outer surface of a casing opposed to blade tips; a second sensor for acquiring a signal from a fixed point on a rotor shaft of the blades; a section configured to extract data groups from an output signal of the first sensor on the basis of information acquired by the second sensor; a section configured to average the data groups; a section configured to determine thresholds from averaged data obtained under a healthy condition; and an assessing section configured to compare magnitude of the thresholds and sensor signals obtained during blade status monitoring. Since a transient displacement of blade position can be sensed, abnormalities can be detected early in this invention. This early detection, in turn, enables a rotation to be stopped during an initial phase of blade damage.Type: GrantFiled: June 26, 2014Date of Patent: June 27, 2017Assignee: Mitsubishi Hitachi Power Systems, Ltd.Inventors: Akira Nishimizu, Toshiyuki Hiraoka, Masahiro Tooma, Soushi Narishige, Tetsuya Matsui
