Recently, owing to the savings of resource and energy, the use of microchannel chips in micro total analysis systems has attracted attention in the medical field. Generally, microchannel chips are composed of plastic or glass. Glass is stronger than plastic in terms of heat and chemical erosion resistance. However, currently, dies for manufacturing glass microchannel chips are not viable because they...
Recently, the use of microchannel chips in micro total analysis systems, which can provide savings of natural resources and energy, has attracted attention in the medical field. Generally, the photolithography technology employed in semiconductor manufacturing is used to manufacture microchannel chip dies. However, it involves several processes such as mask fabrication and the application of a photoresist...
Titanium alloys and Inconel 718 are used in airplane bodies. Pure titanium alloys are used in medical equipment. Wet cutting, which generates a significant amount of cutting fluid, is adopted for the cutting of these difficult-to-cut materials. When near-dry cutting, which is environmentally friendly, is used instead, it easily damages tools, and the stock removal rate and machining accuracy worsen...
In response to global environmental issues, higher efficiency and improved operational reliability are increasingly being requested for steam turbines, essential equipment for thermal power generation. Its material is stainless steel, which is difficult to cut because of high work-hardening trend and high resistance to heat. As its complex shape and high accuracy requirement, conventional methods...
In recent years, optical scanning parts are in demand for use in high-performance information systems for reducing optical aberration, scatter, and diffraction rays. Laser printers use many scanning optical system parts, such as polygon mirrors and photoconductor drums. Polygon mirrors are created by polishing a plating or glassy material to a mirror finish. In this study, we shorten the manufacturing...
