  • Publication number: 20130113494
    Abstract: The present invention relates to a chuck mechanism of a charge-discharge test device for a thin secondary battery, and aims to provide a chuck mechanism having excellent action controllability. The chuck mechanism includes: a chuck drive part which is movable in a direction toward a battery container housing a thin secondary battery; and a chuck activation part which is located away from the chuck drive part in the direction toward the battery container and whose movement in the same direction is restricted. In the chuck mechanism, when the chuck unit is moved in the direction toward the battery container, the chuck drive part activates a chuck member of the chuck activation part whose movement in the same direction is restricted.

  • Patent number: 8390048
    Abstract: For enhancing the high performance of a non-volatile semiconductor memory device having an MONOS type transistor, a non-volatile semiconductor memory device is provided with MONOS type transistors having improved performance in which the memory cell of an MONOS non-volatile memory comprises a control transistor and a memory transistor. A control gate of the control transistor comprises an n-type polycrystal silicon film and is formed over a gate insulative film comprising a silicon oxide film. A memory gate of the memory transistor comprises an n-type polycrystal silicon film and is disposed on one of the side walls of the control gate. The memory gate comprises a doped polycrystal silicon film with a sheet resistance lower than that of the control gate comprising a polycrystal silicon film formed by ion implantation of impurities to the undoped silicon film.

  • Publication number: 20110309837
    Abstract: The present invention relates to a chuck mechanism of a charge/discharge testing device for flat-rechargeable batteries and has a proposition to provide a chuck mechanism that makes it possible to lighten conventionally needed troublesome works, that is, for example, works of storing and fixing a large number of flat-rechargeable batteries in a container, and that is capable of surely chucking the flat-rechargeable batteries (electrodes). The chuck mechanism includes a first guide couplable with a battery storage retaining a plurality of flat-rechargeable batteries arranged in parallel, and a plurality of chuck units continuously joined with the first guide and resiliently arranged in parallel, wherein the chuck units each have a second guide resiliently positioning each of the chuck units with a predetermined number of corresponding flat-rechargeable batteries in the battery storage.
