    摘要： A test handler is provided, which comprises a test tray, at least one opening unit, and a position changing apparatus. The test tray aligns a plurality of inserts on its side. Each insert loads at least one semiconductor device thereon. The opening unit opens inserts at one part of the one side of the test tray. The position changing apparatus moves at least one opening unit in such a way that the at least one opening units can be located at another part of the one side of the test tray, such that the at least one opening units can open inserts at said another part of the one side of the test tray. The present invention can reduce the number of replaced parts according to change in the semiconductor device size, production cost, and part replacement time.

    摘要： An opener and a buffer table for a test handler are disclosed. The opener includes an opening plate, a plurality of pin blocks forming pairs, and at least one or more interval retaining apparatus for retaining an interval between the pin blocks forming a pair. Each of the pin blocks is movably coupled to the opening plate, and includes opening pins for releasing a holding state of a holding apparatus that holds semiconductor devices in a carrier board. Although semiconductor devices to be tested are altered in size and a carrier board loading with the semiconductor devices is thus replaced, the opener does not need to be replaced, thereby reducing the replacement cost and the waste of resources.

    摘要： A reciprocating compressor comprises: a cylinder having an oil pocket on an inner circumferential surface of a piston insertion hole for inserting a piston with a predetermined width and depth; and a piston having a bearing portion protruding so as to slidably contact an inner circumferential surface of the piston insertion hole, and inserted into the piston insertion hole of the cylinder, wherein the bearing portion is formed to have a length shorter than that of the oil pocket of the cylinder. Accordingly, a frictional loss between the cylinder and the piston is reduced.
