A direct internal reforming system of ethanol for a molten carbonate fuel cell (MCFC) is provided. An MCFC anode for a direct internal reforming of ethanol, a manufacturing process thereof, and a direct internal reforming method in MCFC where an ethanol solution is injected into the anode are provided. by the simple process of coating the surface of the anode with small quantity of catalyst, the drawback in that the performance of MCFC is degraded when the ethanol is directly used as a fuel is overcome. Further, an additional apparatus such as an external reforming apparatus and additional cost for pelletizing the catalyst powders are not required, which is economical. Furthermore, the performance improvement enables long-term operation, which contributes to commercialization of MCFC.

A handler for testing semiconductor devices is disclosed which is capable of simplifying the process carried out in an exchanging station, namely, the process of loading/unloading semiconductor devices in/from test trays, and greatly increasing the number of simultaneously testable semiconductor devices. The handler includes a loading station, an unloading station, test trays, an exchanging station comprising a horizontal moving unit for horizontally moving a selected one of the test trays by a predetermined pitch at a working place, a test station in which at least one test board having a plurality of test sockets to be electrically connected with semiconductor devices is mounted, the test station performing a test while connecting the semiconductor devices in one of the test trays, which is fed from the exchanging station to the test station, to the test sockets, device transfer units for transfer the semiconductor devices between the loading station and the exchanging station and between the exchanging station and the unloading station, respectively, and a tray transfer unit for transfer the test trays between the exchanging station and the test station.
摘要:
The present invention relates to a socket assembly for testing semiconductor device comprising a socket board electrically connected to an outside testing device wherein a plurality of connection pins connected to leads of a semiconductor is provided; a socket guide mounted to cover the socket board, with an open part formed so that the semiconductor may in/out, thereby connecting the semiconductor to the connection pins of the socket board; and a spacer interposed between the socket board and the socket guide for maintaining a predetermined distance between the semiconductor and the socket board by touching an surface of the semiconductor having moved into an inside of the socket guide before a surface of each carrier touches the socket guide. According to the present invention, the balls or the leads of each semiconductor may be pressed to the connection pins of the socket in a predetermined depth without replacing the carriers though the semiconductors have the different thicknesses.
