Abstract: Provided is a novel structural electric device having improved safety. More particularly, provided is a novel structural electric device devised to resolve several issues regarding heat generation, ignition, and explosion, which may be caused by a sharp needle-shaped object penetrating an electric device.

Abstract: Provided are an electrode lead of a secondary battery where a protection layer for anti-corrosion is selectively formed at an electrode lead portion at the cell outside and a secondary battery including the same. Since a protection layer for anti-corrosion is selectively formed only on an electrode lead portion at the cell outside, the corrosion of the electrode lead may be prevented from an external environment and the resistance of a cell may be reduced simultaneously.

Abstract: The soldering connector according to the present invention, which electrically connects a plurality of unit cells to each other, comprises a lead-free alloy including tin (Sn) and copper (Cu). According to the present invention, when a secondary battery overheats due to the malfunction thereof, electrical connection between unit cells comprised in a battery module rapidly disconnects under a relatively low temperature and current range, thereby ensuring the safety of the secondary battery.

Abstract: Provided are a pouch-type secondary battery having improved safety, and a battery pack including the pouch-type secondary battery. When inner pressure of a pouch is increased by an overdischarge, the pouch is deformed to separate electrode leads from electrode tabs. When the secondary battery is manufactured, an additional material or device is unnecessary. In addition, since the pouch-type secondary battery fundamentally cuts off electric current when gas is generated therein, the service life and safety of the secondary battery can be significantly improved, and the manufacturing costs and the weight thereof can be reduced. Furthermore, the shape of the secondary battery can be easily modified.

Abstract: A module of a host computer of a semiconductor fabrication management system receives from an operator a plurality of IDs assigned by the operator to each of the wafers, respectively, received in the slots of a wafer cassette. The module searches a database of the host computer to correlate each received wafer ID with a process step ID, and the process step ID with a process program ID (PPID). Process condition data is formulated from the correlated process step IDs and PPIDs. At this point, the semiconductor fabrication management system is used to determine whether the operator has inputted a track-in signal to the system. If the track-in signal has been inputted, the processing condition data is downloaded to a server of the semiconductor processing equipment. The downloaded process condition data is used to change, if necessary, an equipment control message stored in the server.
