Abstract: An apparatus for manufacturing a unit cell including a first and second roller is provided. The first roller is positioned on a first side of the first and second separators. The second roller is positioned on a second side of the first and second separators opposite the first side wherein the second roller is aligned with the first roller along an axis and defines an oval shape having a long axis and a short axis. The second roller is configured to contact the second separator and press the first and second separators against the first roller at portions of the first and second separators which are between adjacent electrodes. One of the lower roller or the upper roller is heated so as to thermally fuse the separators together.

Abstract: An apparatus for manufacturing a unit cell cuts lower and upper separators between sets of adjacent electrodes. In a state of a process of manufacturing the unit cell, the lower and upper separators continuously move in a longitudinal direction; and the electrodes are stacked between the separators and on the upper separator, respectively. The apparatus includes a lower block disposed under the lower separator and an upper block vertically aligned with the lower block above the upper separator. A lower end of a cutter is installed for access to the inside and outside. The upper block descends to press the separators to a surface of the lower block. One or both of the upper and lower blocks is heated to a predetermined temperature to thermally fuse pressed points of the separators. The cutter protrudes from the upper block to perform cutting at points at which the separators are pressed.

Abstract: A computer mouse interface system has a mouse section which includes a tactile feedback section arranged to stimulate a finger of a user through a plurality of pins, so that the user can feel the nature of a virtual object displayed on a computer screen. The system further has a thermal feedback section arranged on a side of the mouse section to provide thermal information of the virtual object to the finger of the user. The thermal feedback section comprises a thermoelement for discharging or absorbing heat in response to a control signal according to a temperature variation when a users finger is contact with the virtual object, a cover brought into contact with a surface of the thermoelement to receive heat from the thermoelement, and a cooler brought into contact with another surface of the thermoelement to absorb heat discharged from the thermoelement.

Abstract: Disclosed are an apparatus for preparing hydrogen and carbon monoxide (hereinafter, referred to as “synthesis gas”) from methane and an oxygen containing compound using an atmospheric pressure barrier discharge reaction and a method for preparing the synthesis gas using the same. According to the invention, when the synthesis gas is prepared from the methane and the oxygen containing compound using the barrier discharge plasma at the low temperature, it is possible to obtain the same performance as the case using a high temperature catalyst reaction more economically at a time. In particular, according to the invention, it is possible to save the energy by about 35%, compared to the case using the prior heating only.

Abstract: A mouse interface system is provided that allows a user to feel a virtual object displayed by a computer on a display device. The system includes (a) a force feedback device for providing the user with kinesthetic feedback related to mechanical properties in a predetermined direction of the virtual object, (b) a tactile feedback device for providing the user with normal stimulation related to texture of the virtual object, and (c) a linear actuator for providing the tactile feedback device with a translational movement so that the distal end portion of each pin moves in a substantially lateral direction with respect to the user's skin.
