Manufacturing method of cell cryopreservation tube comprises the steps of providing a metal tubule having an inside wall and an outside wall. Smoothing the inside wall of the metal tubule thereby forming a smooth surface on the inside wall, and the roughness of the smooth surface is named the first roughness. Roughening the outside wall of the metal tubule thereby forming a rough surface on the outside wall, and the roughness of the rough surface is called the second roughness. The magnitude of the second roughness is greater than the first roughness.
摘要:
A method and apparatus for removing conductive material from a microelectronic substrate. In one embodiment, a support member supports a microelectronic substrate relative to a material removal medium, which can include first and second electrodes and a polishing pad. One or more electrolytes are disposed between the electrodes and the microelectronic substrate to electrically link the electrodes to the microelectronic substrate. The electrodes are then coupled to a source of varying current that electrically removes the conductive material from the substrate. The microelectronic substrate and/or the electrodes can be moved relative to each other to position the electrodes relative to a selected portion of the microelectronic substrate, and/or to polish the microelectronic substrate. The material removal medium can remove gas formed during the process from the microelectronic substrate and/or the electrodes. The medium can also have different first and second electrical characteristics to provide different levels of electrical coupling to different regions of the microelectronic substrate.

A method for manufacturing a mirror surface tube for a photosensitive drum of a copying machine or the like, by which an external surface of an aluminium or aluminium alloy tube can be mirror-processed with high accuracy without surface defects, and in such a way that good quality required for a photosensitive drum is ensured and dimension accuracy, such as roundness, and production yield is improved involves a first step in which an aluminium or aluminium alloy tube, finished in a predetermined shape and dimension with surface roughness of 10 microns or less, is processed by a centerless grinding process. Then, in a second step, a grinding process is performed using an electrolytic integrated polishing apparatus including a tool electrode mechanism having an elastic grindstone so as to make a mirror surface tube having the surface roughness of 2.0 microns or less. Further, preferably, in a third stage, a roller burnishing process is performed to finish the tube to a surface roughness of 0.5 microns or less.
