Patent number: 10410811Abstract: A power tool (1) includes an electric motor (2) as a drive source and a start switch (20; 61) that starts the electric motor (2) and is lockable in an ON position in a lock-ON state. An electromagnetic actuator (30; 40; 50; 60) pushes out or pulls in an actuation pin (30a; 40a; 50a; 60a) with respect to a body of the electromagnetic actuator (30; 40; 50; 60) in response to cutting off of a supply of electrical current to the power tool (1). The pushed-out or pulled-in actuation pin, directly or indirectly, disengages the start switch (20; 61) from the lock-ON state and/or prevents the start switch (20; 61) from being shifted into the lock-ON state.Type: GrantFiled: September 14, 2016Date of Patent: September 10, 2019Assignee: MAKITA CORPORATIONInventors: Takamasa Hanai, Hikaru Sunabe, Satoshi Ninagawa, Shin Nakamura, Masatoshi Nakahama, Kazusa Fukuda, Kenichi Miyata

Patent number: 10363650Abstract: In a rack and pinion mechanism 80, a driving-side pinion gear 83 and a driven-side pinion gear 86 are provided to be coaxially rotatable relative to each other within a predetermined angle range. Because of this construction, in a case where a time when a driver 3 reaches an advancing end position and contacts an advancing end damper 19 deviates from a time when a weight device 5 reaches a retracting end position and contacts a moving end damper 7, an excessive external force is not applied to engaging teeth 81a and 82a by relative rotation of the pinion gears 83 and 86. Thus, due to this construction, durability of the rack and pinion mechanism 80, where end impacts are absorbed through elastic deformation, is improved.Type: GrantFiled: October 14, 2016Date of Patent: July 30, 2019Assignee: MAKITA CORPORATIONInventors: Isao Miyashita, Kenichi Miyata

Patent number: 10006450Abstract: An air compressor includes an internal combustion engine for driving an air compressing part that generates compressed air, which is stored in an air-storage tank. At a point in time when the air pressure inside the air-storage tank has increased to a first set pressure, the supply of fuel to the engine is cut off, thereby stopping the engine and the combustion of fuel. At a point in time when the air pressure inside the air-storage tank has decreased from the first set pressure to a second set pressure, a starter motor is started up to resume the operation of the engine.Type: GrantFiled: September 18, 2015Date of Patent: June 26, 2018Assignee: MAKITA CORPORATIONInventors: Noriyuki Nishido, Kenichi Miyata
