摘要： A main body of the cleaning apparatus is of a cylindrical structure and internally provided with a compression spring and a movable seal valve which is matched with the inner wall of a casing of the cleaning apparatus. When cleaning solution flows in the cleaning apparatus through a cleaning solution inlet on a base, the pressure of the cleaning solution overcomes the spring force of the compression spring and drives a transmission guide rod, the movable seal valve and a nozzle to move together, and the transmission guide rod stops when moving to a limit position. When cleaning is finished, the pressure of the cleaning solution disappears, the movable seal valve is closed under the function of the compression spring then the transmission guide rod retracts into the casing and closes.

摘要： A FIFO memory device, FIFO control method and graphics processing system are disclosed which incorporate spread-spectrum EMI compensation. In one embodiment, a FIFO memory device and method includes generating a spread-spectrum adjustment signal for a spread-spectrum FIFO based on an address offset associated with a read and write address associated with a spread-spectrum FIFO. The method includes adjusting the spread-spectrum clock signal in response to the spread-spectrum adjustment signal based on the address offset associated with the read and write address. A spread-spectrum FIFO receives data from a data source, such as a graphics data source, which may include a memory such as a RAMDAC. The data can be provided by a display engine or other suitable information provider. The spread-spectrum FIFO is operatively responsive to both a spread-spectrum clock signal and another clock signal to suitably adjust an output frequency of data read from the spread-spectrum FIFO using fewer than two complete display paths and associated circuitry and operations.
