Patent number: 10006433Abstract: In a laser ignition device which is mounted in an internal combustion engine and at least includes a laser spark plug equipped with an optical window which protects an optical device from high temperature and high pressure generated in a combustion chamber and a prechamber cap equipped with a cylindrical prechamber, a prechamber throat portion that is a bottomed cylinder with a sectional area smaller than that of the prechamber, and a plurality of prechamber spray holes which communicate with a combustion chamber on a side of a closed end of the prechamber throat portion, the prechamber cap is arranged between the optical window and the combustion chamber. A converging point FP is located inside the prechamber to ignite an air-fuel mixture delivered into the prechamber, thereby jetting combustion flames from the prechamber into the combustion chamber to fire the internal combustion engine.Type: GrantFiled: July 27, 2015Date of Patent: June 26, 2018Assignees: DENSO CORPORATION, MITSUBISHI HEAVY INDUSTRIES ENGINE & TURBOCHARGER, LTD.Inventors: Kenji Kanehara, Naoki Kido, Akimitsu Sugiura, Nobuyuki Taguchi, Ryu Suzuki, Akihiro Yuuki, Minoru Ichihara, Tomohiro Noguchi

Patent number: 9862055Abstract: A processing apparatus and a processing method which perform processing more accurately with a simple structure are provided. The processing apparatus includes an irradiation head 16 and a control device. The irradiation head 16 includes a laser turning unit 35 and a condensing optical system 37. The laser turning unit 35 includes a first prism 51, a second prism 52, a first rotating mechanism 53, and a second rotating mechanism 54. The control device adjusts the differences between rotation speeds and phase angles of the first prism 51 and the second prism 52 based on a relation between at least a heat affected layer of a workpiece and a turning speed of laser.Type: GrantFiled: November 22, 2013Date of Patent: January 9, 2018Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Saneyuki Goya, Masato Kinouchi, Minoru Danno, Toshiya Watanabe, Takashi Ishide, Tsugumaru Yamashita, Yoshihito Fujita, Makoto Yamasaki, Ryu Suzuki, Kohei Kanaoka

Patent number: 9757816Abstract: Provided are a machining device and a machining method in which machining of higher precision can be performed with a simple configuration. The machining device has an irradiation head (16) and a controller; and the irradiation head (16) can be divided into a collimate optical system, a laser revolving unit (35), and a light collection optical system (37). The laser revolving unit (35) has a first prism (51), a second prism (52), a first rotation mechanism (53), and a second rotation mechanism (54). The controller controls the rotational speeds and the difference in phase angles of the first prism (51) and the second prism (52), on the basis of at least the relationship between a heat affected layer of a member to be machined and the revolving speed of the laser.Type: GrantFiled: November 22, 2013Date of Patent: September 12, 2017Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Yoshihito Fujita, Tsugumaru Yamashita, Saneyuki Goya, Makoto Yamasaki, Ryu Suzuki, Kohei Kanaoka, Takashi Ishide, Toshiya Watanabe
