Abstract: The invention relates to a system for treating a surface of an article with a liquid material by dipping. This system includes (a) a major tank having therein the liquid material for dipping the article thereinto; and (b) a circulatory mechanism for circulating the liquid material through the major tank. The circulatory mechanism is arranged to make a flow of the liquid material through the major tank such that the majority of the flow is in one direction that is substantially along the longitudinal direction of the major tank. Thus, contaminants and/or bubbles are not distributed over the entire major tank, but are effectively promptly removed from the major tank. The flow of the liquid material may include a first flow of the liquid material in the major tank and a second flow that is lower than the first flow in position. The first and second flows run substantially in parallel with each other, before the first and second flows reach a downstream end thereof in the major tank.

Abstract: A method of forming an artificial snow surface and an ice crusher machine used in the method are disclosed. Also disclosed is a method of maintaining a snow surface. The surface forming method has the steps of spraying water onto a floor incorporating a refrigerating unit; freezing the water by the refrigerating unit to form an ice layer on the floor; shaving a surface of the ice layer to generate artificial snow consisting of fine ice particles; and forming an artificial snow layer having an artificial snow surface by leaving the shaved snow on the remain of the ice layer in the course of the shaving step. The ice crushing machine has a self-propeling device for propelling the machine body on the ice layer while shaving the surface of the layer to produce fine ice particles behind the propelling path of the machine. The surface maintaining method has the step of dehumidifying air present adjacent the snow surface to avoid frosting of water content in the air on the surface.

Abstract: A method of forming an artificial snow layer is disclosed. Water content is added to to atmosphere above a floor by a humidifying device, or water mist is added to the atmosphere by a water-mist supplying device.
