摘要:
Air trapped in a blind hole during processing of the blind hole with a liquid is eliminated by circulating the liquid along a surface-to-be-processed in substantially a single direction at all times and by setting a velocity gradient of the liquid over the surface to at least 300/second.
摘要:
An air trap in a blind hole is eliminated by circulating a liquid chemical along a surface-to-be-processed in substantially a given direction at all times and by setting a velocity gradient of the liquid chemical over the surface to 300/second or more thereby eliminating the air trap in the blind hole.

摘要:
A sorting method for plastics, including: sorting a predetermined plastic piece from a mixed plastic piece group including plastic pieces of a plurality of types; identifying the plurality of types of the plastic pieces; and calculating mixing rates of the plurality of types in the mixed plastic piece group based on a result obtained in the identifying, the identifying is performed on the mixed plastic piece group prior to the sorting, a sorting condition of the sorting is set based on an identification result obtained in the identifying, the identifying includes identifying the plurality of types of the plastic pieces with a beam.
