摘要:
The present invention features a high-capacity anode material for rapidly chargeable and dischargeable lithium secondary batteries, which is composed of Li4Ti5O12 nanoparticles. The Li4Ti5O12 nanoparticles of the present invention exhibit excellent crystallinity and high rate capability compared to those synthesized using a conventional polyol process or solid reaction process by converting Li4Ti5O12, which is a zero-strain insert material spotlighted as an anode active material for lithium secondary batteries, into Li4Ti5O12, having a high crystalline nanostructure using a solvothermal synthesis process without performing additional heat treatment. The present invention also features methods of, and a method of preparing the high-capacity anode materials described herein.

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:
Provided are a cooker and a method for controlling the same. Levels driven by a plurality of heat sources are controlled by input driving levels of all the heat sources received by an input unit. Accordingly, there is an advantage in that foods are more swiftly cooked by the plurality of heat sources.
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.
