摘要： A washing method provides a liquid jet washing by jetting a liquid against a rotating thin-plate-shaped workpiece from a nozzle which shifts while being positioned opposite a front or back surface of the workpiece, thus removing dust adhering to the front or back surface and thereby washing the workpiece. The locus of the shifting nozzle is caused to pass in the vicinity of, but not over, the center of rotation of the workpiece. Electronic circuitry present at the central portion of workpiece is prevented from suffering electrostatic breakage caused by collision with washing liquid. At the same time, an appropriate quantity of washing liquid is made to collide with the entire surface of a workpiece, so that the workpiece can be washed satisfactorily.

摘要： Disclosed is an apparatus for and a method of thixocasting a cast iron, that can effectively prevent the scale from mixing in the die (cavity) thereby to obtain sound iron castings having good mechanical properties. The apparatus includes at least a pair of dies that can freely opened and closed to define a cavity to be filled under a pressure, and an injector that injects the semi-molten iron into the cavity through a hole in a gate at the entry of the cavity so as to throttle the entry. The gate is a separate member disposed at the entry of the cavity every time an injection casting operation is carried out and is taken out together with the casting after the injection casting operation.

摘要： A method of and an apparatus for cleaning workpiece is suitable for cleaning a substrate such as a semiconductor substrate, a glass substrate, or a liquid crystal panel to a high level of cleanliness. The method of cleaning a workpiece comprises the steps of holding a workpiece, scrubbing the workpiece with a cleaning member, and rubbing the cleaning member against a member having a rough surface to carry out a self-cleaning of the cleaning member. The cleaning member which is contaminated by having scrubbed the workpiece is rubbed against the rough surface, and the rough surface scrapes the contaminant off the cleaning member. Therefore, the contaminant can effectively be removed from the cleaning member, and hence the cleaning member has a high self-cleaning effect.
