Abstract:
A patterned nonreciprocal optical resonator structure is provided that includes a resonator structure that receives an optical signal. A top cladding layer is deposited on a selective portion of the resonator structure. The top cladding layer is patterned so as to expose the core of the resonator structure defined by the selective portion. A magneto-optically active layer includes a magneto-optical medium being deposited on the exposed core of the resonator structure so as to generate optical non-reciprocity.
Abstract:
A dual display folder type terminal having a hinge includes a manipulation unit formed in the hinge, wherein the inventive implementation of the hinge provides various function commands without the need of an additional space in the terminal. As a result, the size of the terminal doesn't suffer when implementing the manipulation unit. Further, the dual display folder type terminal can operate different modes based on the opening angle of a folder relative to the other folder.
Abstract:
A cover for covering a folder type terminal including a first frame, a second frame, and a hinge for rotatably connecting the first frame and the second frame, the folder type terminal cover device includes: a first outer cover for covering the first frame; a second outer cover for covering the second frame; and a hinge cover for covering the hinge and in which a separation distance from the hinge increases when the folder type terminal is unfolded from a folded state. Thereby, an appearance and grip impression of the folder type terminal can be improved, and when the folder type terminal is put on a table in an unfolded state, the folder type terminal can maintain a predetermined angle from a table plane without a separate device.
Abstract:
The present invention relates to an apparatus for preventing cavitation damage to a diesel engine fuel injection pump, wherein a pressure control valve for shutting a barrel port is mounted on a deflector or a barrel of the fuel injection pump to increase the fuel pressure in the barrel port during an early stage of fuel compression. This prevents fountain-type or jet-type cavitation from occurring before and after the opening of the barrel port during a late stage of fuel compression, thereby preventing corrosion damage caused by cavitation occurring mainly in a plunger and the barrel port of the fuel injection pump. The key technical features of the present invention are for an apparatus for preventing cavitation damage to a diesel engine fuel injection pump having a fuel intake valve and the barrel port for the inflow and outflow of fuel, respectively, comprising: a valve member mounted on the barrel port to shut the barrel port during an early stage of fuel compression performed by the upward movement of the plunger to increase the pressure in the barrel port; a valve housing installed in the deflector or the barrel of a pump housing to support the valve member; and a pressure control valve constituted by a spring interposed between the valve member and the valve housing to elastically support the valve member. The barrel port is shut to increase the pressure therein during the early stage of fuel compression, and thus preventing cavitation caused by the pressure difference between the barrel port and a pump chamber before and after the opening of the barrel port during the late stage of fuel compression. When the pressure of fuel in the barrel port exceeds a level higher than an open level, the barrel port opens to discharge fuel.

Abstract:
An architecture of the layout of the MTCMOS standard cell designed for low power consumption is supplemented so that the pick-up cells are included in the power line of the MTCMOS cell. Therefore, when the logic circuit is constructed using the library layout of the MTCMOS cell in which the related pick-up cells are not included, pick-up cells consisting of only the ends of the pick-up cells are not needed every 50 μm during the placement of the MTCMOS standard cell. The flexibility of the cell placement may thereby be improved. In addition, since additional space for the pick-up cells is not required, the size of the MTCMOS may be reduced, saving space on the semiconductor substrate.
