Patent number: 11964356Abstract: A hand-held tool, such as a disc grinder, is used to perform work at a high work site, a countermeasure is taken to prevent the hand-held tool from falling by using a suspension tool, such as a tether strap. If a coupling part that couples the suspension tool to the hand-held tool is damaged, this fact is notified to a user. Thereby, an original function of the suspension tool can be reliably performed. If a large impact is applied to a coupling member via a suspension tool, the coupling member is displaced to a second position, due to the deformation of a first position retaining member. A conductive portion disengages from contacts to cause a power circuit to be shut off, thereby prohibiting a main body part from being activated.Type: GrantFiled: March 27, 2019Date of Patent: April 23, 2024Assignee: MAKITA CORPORATIONInventors: Ryosuke Otani, Junya Ishikawa, Takafumi Kotsuji, Satoshi Ninagawa, Ken Goto, Yu Eto

Patent number: 11355784Abstract: In initial charge and discharge, decomposition products or a gas is generated, degrading a battery. At least one of solvents (e.g., ethylene carbonate) used for an electrolytic solution is brought into contact with a positive electrode and a negative electrode and then charge is performed to some degree, and after that, a different solvent or electrolytic solution (e.g., ethyl methyl carbonate or vinylene carbonate) was added to adjust the electrolytic solution and then charge is performed. Through this process, stable coating films are formed in initial charge and discharge, which stably inhibits a side reaction between the electrolytic solution and an active material.Type: GrantFiled: October 24, 2019Date of Patent: June 7, 2022Assignee: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.Inventors: Teppei Oguni, Junya Goto, Ai Nakagawa
