Abstract: Provided is a method for removing a laminated material on a surface of a silicon wafer capable of considerably efficiently removing a laminated material on a surface of a silicon wafer at a low cost with a simple apparatus without a negative effect on environment or a serious damage on the silicon wafer as a substrate. A blasting process was performed by spraying boron carbide (B4C) having a particle size of #220 as an abrasive on a laminate surface of a laminated material of an intermediately discharged silicon wafer using a blasting machine (dry type that sprays a dry abrasive, and a gravity type that sprays the abrasive fallen from a tank of the abrasive due to gravity on a compressed air) under spray conditions of a spray distance=120 mm and a spray pressure=0.2 MPa for five seconds.

Abstract: A refrigeration system and a refrigerating appliance. The refrigeration system includes: a refrigeration assembly including a compressor, and an evaporator, forming a refrigeration circuit; and a defrost bypass pipeline connected to the refrigeration circuit for circulating refrigerant from the compressor to generate heat; the defrost bypass pipeline is thermally connected with the evaporator to heat the evaporator. By adding a defrost bypass pipeline connected to the refrigeration circuit and thermally connecting it with the evaporator, the evaporator can be heated for defrosting when the refrigerant from the compressor flows through the defrost bypass pipeline. Since the refrigerant from the compressor can produce a significant amount of heat when passing through the defrost bypass pipeline, this manner of defrosting can enhance the defrosting rate of the evaporator and enable quick, efficient, and thorough defrosting.
