  • Patent number: 10424807
    Abstract: A fuel cell system includes a fuel cell stack including an air electrode and a fuel electrode, a stack housing having a hollow therein to accommodate the fuel cell stack in the hollow, an air compressor configured to pump air to supply the air to the air electrode, a ventilation pipe connecting an entrance of the air compressor and the hollow, and at least one vent hole provided on an outer wall of the stack housing such that the hollow and an outside of the stack housing communicate with each other. An interior of the stack housing is ventilated by lowering of a pressure at the entrance of the air compressor, which is generated as the air compressor is operated, while air outside the stack housing is suctioned into the entrance of the air compressor after passing through the vent hole, the hollow, and the ventilation pipe.

  • Publication number: 20190143743
    Abstract: The present application relates to a pattern forming method for quartz surface and a pattern forming device for quartz surface. According to the pattern forming method for quartz surface of the present application, by comprising a step of forming a pattern and a step of forming a color, it is possible to freely express the color on the pattern simultaneously along with forming the pattern on the quartz surface. And, in addition to these steps, by optionally comprising a step of additionally forming a pattern, it is possible to freely form a desired pattern on the quartz surface, and, by adding long line type patterns on the quartz surface unlike existing conventional quartz surfaces, it is possible to produce the quartz surface showing patterns and textures which are more natural and close to natural stone.

  • Patent number: 6362757
    Abstract: A coding method for converting m-bit input data into n-bit codeword satisfying DC-free and minimum bandwidth characteristics that includes the following: Select the number of input bits m and the number of output bits n for an (m,n) block code. Accumulate a sufficient number of BUDA (binary unit DSV and ASV) cells to form a BUDA stack for derivation of the state diagram. Pick one node as a state, and secure at least 2{circumflex over ( )}m exit paths of an n-hop length, and denote each terminating node of each path as another state. Start with a new state and repeat the previous step. If the stack needs to be expanded to complete the state diagram, add more cells to the stack either horizontally or vertically as appropriate. Reduce the number of states as possible with all transition paths terminating on one of the arranged states. At each state, arrange the mapping table as an input m-bit combination to an output n-bit combination.
