摘要： A stage apparatus that includes a stage and moves the stage in at least a first direction. The stage apparatus also includes a plurality of holding units fixed on the stage to extend in the first direction, in which the first direction is a longitudinal direction. Each of the holding units includes a first portion. A second portion is arranged between the first portion and the stage and a third portion is arranged between the second portion and the stage. The first portion includes a holding surface to hold an object. A length of the second portion in the first direction is less than a length of the first portion in the first direction, and the length of the second portion in the first direction is less than a length of the third portion in the first direction. Ends of the second portion are determined by two slits extending from both ends of the holding units in the first direction towards a central portion of the holding units, and the first portion is connected to the third portion at only one point via the second portion.

摘要： A heatsink of the present invention has a column having a heat conducting plate with a heat receiving face contacting a heat producing element. On the side faces of the column are a plurality of first slits and a plurality of second slits disposed transversely to the plurality of first slits. These slits form a plurality of pillar-type protrusions functioning as fins for cooling. The depths of the first and second slits in the column are different, and this difference in levels are used to cause the fluid for cooling to form a turbulent flow. A cross section of the column tapers off gradually or in stages as the vertical distance increases from the heat receiving face. A cooling apparatus for the present invention includes a cooling means mounted on the heatsink of the present invention. The cooling apparatus for the present invention enjoys a high cooling ability and reduced size.
