Patent number: 11697177Abstract: A laser processing method for laser processing of a workpiece made of a base material and a fiber reinforced composite material containing fibers having a thermal conductivity and a processing threshold higher than physical properties of glass fibers. The laser processing method includes a step of processing the workpiece by forming a plurality of through-holes extending through the workpiece by irradiating the workpiece with pulsed laser light from a processing head while relatively moving the workpiece and the processing head in a predetermined cutting direction. The pulsed laser light has a pulse width smaller than 1 ms and an energy density capable of forming each of the through-holes by a single pulse.Type: GrantFiled: September 21, 2021Date of Patent: July 11, 2023Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Koji Funaoka, Masayuki Saiki, Takashi Inoue

Patent number: 11389907Abstract: A laser machining apparatus that separates a workpiece into a machined product and a remnant material by cutting using irradiation with a laser beam includes: a nozzle that squirts gas at a machining point; a rotation mechanism that causes the nozzle or the workpiece to rotate about an optical axis; and a controller that performs control of the rotation mechanism. This control causes the nozzle, which squirts the gas at the machining point, to be at the machined product side during the cutting.Type: GrantFiled: December 3, 2018Date of Patent: July 19, 2022Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Koji Funaoka, Masayuki Saiki, Takayuki Hirano, Hiroaki Ashizawa

Patent number: 6397804Abstract: A valve drive mechanism includes a generally cylindrically shaped tappet assembly (24) comprising a center tappet (41 ) and a side tappet (42). The center tappet (41 ) has a circular-arcuate side walls (41c) formed with vertical side shrouds (41d) at opposite sides of each side wall (41c) which overlap and slide contact with opposite end guide walls (42h) of the side tappet (42), respectively. When the tappet assembly (24) is in an unlocked state so as to transmit rotation of the side cams (25, 27), the vertical side shroud (41d) of the center tappet (41 ) slide on the vertical side walls (42h) of the side tappet 42 so as thereby to guide slide movement of the center tappet (41) relative to the side tappet (42).Type: GrantFiled: August 10, 2001Date of Patent: June 4, 2002Assignee: Mazda Motor CorporationInventors: Setsuo Harada, Hiroyuki Oda, Hirokazu Matsuura, Kouji Asanomi, Masayuki Saiki
