Abstract:
The present invention pertains to a tunnel excavation device, which includes an excavation head, a main body on which the excavation head is rotatably mounted, a motor provided in the main body and rotates the excavation head, and a controller for controlling the motor, wherein the excavation head includes a perforating means formed by maintaining a predetermined interval from the center of a body part, which has a front surface formed in the shape of a circular plate, to the outer surface of the body part, an injection means for injecting water and liquid nitrogen into the hole formed by the perforating means, and a plurality of cutters provided on the surface of the main body for crushing the bedrock. According to the present invention, the perforating means such as a laser drill or the like forms a hole and water and liquid nitrogen are injected into the hole so as to crush the bedrock when the excavation work is carried out. Therefore, vibrations, noise and the dust may be reduced around the work site, and the progress speed of processes may be increased. In particular, the one day excavation distance becomes longer than the conventional TBM (tunnel boring machine) such that the entire tunnel construction period is reduced. Furthermore, the lifespan is elongated due to prevention of the abrasion of a cutter such that the cutter replacement time becomes longer, and the maintenance costs can be reduced.
Abstract:
A nozzle for holding a substrate may include a nozzle head and a nozzle body. The nozzle head may provide the substrate with compressed air. The nozzle body may be connected to the nozzle head. The nozzle body may be arranged facing the semiconductor substrate. The nozzle body may have a substantially flat supporting surface which provides a uniform gap between the substrate and the nozzle body. The nozzle body may have a first passageway which allows the compressed air to pass through toward the substrate to form a vacuum between the substantially flat supporting surface and the substrate.

A multi-vision system and a method of controlling a display device usable in a multi-vision environment are disclosed. The multi-vision system includes a video source providing a video signal, a user input unit receiving multi-vision arrangement information from a user, a display device coupled to the video source for receiving the video signal. The display device, which is further coupled to the user input unit for receiving the arrangement information, initially determines an image portion of the video signal on the basis of the received arrangement information, adjusts a size of the determined image portion, and displays the size-adjusted image portion. The arrangement information indicates a user-preferred multi-vision arrangement and a position of the display device in the multi-vision arrangement.

Abstract:
The present invention relates to an active pressurization system making use of a platform track area upper slab of an underground train station. A track area, where a fast train and a slow train pass through an underground train station, is divided into a fast-train running space and a slow-train running space by means of a partition wall. Formed in an upper slab of the train station, there are a first and a second air-stream out- and in-flow space respectively linking to the fast-train running space and the slow-train running space. The front end of the second air-stream out- and in-flow space is provided with a first port and a first damper, while the rear end is provided with a second port and a second damper. The second air-stream out- and in-flow space is provided with a third port for venting of the slow-train running space. The first air-stream out- and in-flow space is provided with a fourth port for venting of the fast-train running space. When a fast train is running, a control panel that receives a sensing signal input from a pressure sensor for sensing pressure ensures that, on the slow-train running space where there is no slow train waiting, the first and second ports are closed and the first and second dampers are open and the third port is open and on the fast-train running space the fourth port is open, while on the slow-train running space where there is a slow train waiting, the first and second ports are open and the first and second dampers are closed and an air supplying and venting fan is driven in such a way as to supply air to the slow-train running space where there is a slow train waiting. The present invention makes it possible to solve the problem of ringing in the ears of waiting passengers by providing the fast-train running space where fast trains pass through and the slow-train running space where slow trains either stop or pass through, and by actively adjusting the supply and venting of air.
Abstract:
Provided is an anticancer agent which comprises an anti-PD-1 antibody or an anti-PD-L1 antibody as an active ingredient, functioning to reverse the unresponsiveness of iNKT cells in which anergy has been induced by administration with an iNKT cell ligand. The anti-PD-1 or anti-PD-L1 antibody blocks the PD-1/PD-L1-mediated signaling pathway not only to prevent the iNKT cell ligand-induced iNKT cell anergy, but also to reverse the unresponsiveness of already anergic iNKT cells to produce cytokines. In addition, the anti-PD1 or anti-PD-L1 antibody ensures the potent anti-tumor activity of iNKT cells as demonstrated by a significant reduction in the number of metastatic nodules in B16F10 melanoma metastasis models in vivo. Collectively, the anticancer agent can be very useful in the treatment of cancer, particularly metastatic cancer.
