The present disclosure relates to a solenoid valve. The solenoid valve includes an armature provided inside the sleeve, a plunger configured to ascend and descend by the operation of the armature, an elastic member configured to press the plunger toward the armature, a magnet core having a through hole in which the plunger and the elastic member are provided and forming an inner space in a longitudinal direction, a valve seat provided in the inner space and on which an orifice penetrating in an axial direction is formed to be opened and closed by the plunger, and a plurality of flow resistance members each including a ring body interposed between the valve seat and the magnet core to generate a flow resistance of a braking fluid, and a slot formed at one side of the ring body to penetrate through the ring body so that the braking fluid passes therethrough.

A dewatering unit in the form of a railcar having bogies thereon to move the unit on rail tracks. The dewatering unit has first and second ends, first and second sides, and a bottom that bound and define an interior chamber. A conveyor is provided in the interior chamber and screens are located in the bottom and first and second sides. A grizzly is located below an opening in the unit's top and above the conveyor. Stabilizing assemblies are deployed to contact the ground and lift some weight off of the bogies prior to loading. A solid material/liquid mixture is dropped through the opening and onto the grizzly which partially fractures the solid material. Further fracturing is undertaken by conveyor drag bars and crushers located adjacent the conveyor. Liquid drains from the unit through the screens. The dewatered solid material is lifted out of the unit by the conveyor.

A method for processing a blood sample is provided that can improve the recovery rate of deformable rare cells that would easily pass through a filter and small rare cells while reducing the filtration area of the filter, and that can recover the rare cells alive.

In one aspect, the present disclosure relates to a method for separating or detecting rare cells in a blood sample using a filter including holes with a hole density of at least 200 holes/mm.sup.2 to 40000 holes/mm.sup.2, wherein the holes are in the form of an ellipse with a minor axis diameter of 3.0 μm to 15 μm and a major axis diameter of 1.1 times to 3 times as long as the minor axis diameter, or the holes have a shape that contains the ellipse and is in contact with the ellipse on at least two points including both ends of the major axis of the ellipse. The method includes separating or detecting rare cells by filtering the blood sample in a volume of 6 μl/hole or less with respect to a hole of the filter.

Provided is a multi-layered filter for separating blood components and a disease diagnosis kit using the same. The multi-layered filter for separating blood components may include a first filter unit configured to separate blood cells from a whole blood sample, a second filter unit configured to separate cell fragments having blood platelet or exosome, and a third filter unit configured to separate protein, wherein the whole blood sample is separated into blood components by passing through the filter units provided to have different pore sizes, thereby effectively separating individual components of the blood without a separate machine. In addition, after filtering, the multi-layered filter may be disassembled to diagnose each component remaining in the filter so as to be utilized for diagnosis.
