A study of crack generation at loading/unloading process in wheel cleaving (Circular/half-penny crack generation mechanisms)
Autor: Kentaro IMAI, Tomoki ASARI, Yuichiro MATSUMOTO, Souta MATSUSAKA, Hirofumi HIDAI, Akira CHIBA, Noboru MORITA
Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 87, Iss 902, Pp 21-00190-21-00190 (2021)
Wheel cleaving is one of the dividing methods of glass substrates, and is widely used in industrial scenes like manufacturing of flat panel displays. However, the crack generation mechanisms are not fully understood and therefore, the processing cond

Selective component nanoparticle precipitation from Invar 42 during metal particle migration by laser irradiation in silica glass
Autor: Hirofumi Hidai, Tatsuki Iwamoto, Souta Matsusaka, Akira Chiba, Tetsuo Kishi, Noboru Morita
Publikováno v: Journal of Experimental Nanoscience, Vol 12, Iss 1, Pp 263-269 (2017)
Laser illumination on a nickel sphere in silica glass has shown to migrate the sphere towards the light source with a nickel nanoparticle precipitated around the sphere. The selective nanoparticle precipitation by Invar 42 sphere migration in silica

Development of the high precision measurement device of static friction characteristics between surfaces at the fixed coupling section
Autor: Fumihiko INAGAKI, Noboru MORITA, Hirofumi HIDAI, Souta MATSUSAKA, Tatsuo OHMORI, Shinji SHIMIZU, Akira CHIBA, Yuichiro MATSUMOTO
Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 85, Iss 878, Pp 19-00275-19-00275 (2019)
Mechanical systems have many joints within. It is well known that the parameters such as contact stiffness, static friction coefficient, kinetic friction coefficient and attenuation coefficient affect static, kinetic, thermal and motion characteristi

Metal sphere migration in glass by surface heating using CO2 laser
Autor: Noboru Morita, Hirofumi Hidai, Souta Matsusaka, Arata Sawafuji, Akira Chiba
Publikováno v: Precision Engineering. 73:326-331
The interfacial tension gradient originating from a temperature gradient causes particle migration. Previously, the authors reported the manipulation of a metal sphere in a glass using a near-infrared (NIR) laser. The NIR laser beam was not absorbed

Morphology of Cleaved Surface and Observation of In Situ Crack Propagation During Cleaving
Autor: Hirofumi Hidai, Noboru Morita, Akira Chiba, Souta Matsusaka, Soshi Iwatsuki
Publikováno v: International Journal of Automation Technology. 15:483-491
In laser cleaving, the thermal stress caused by laser heating and water-jet cooling propagates previously induced cracks in the workpiece material. The laser-cleaving conditions affect the quality of the fracture surface, and therefore, elucidating t
