Abstract: PURPOSE: An automatic washing filter for clear water and seawater is provided to easily wash the strainer by just opening a discharge valve. CONSTITUTION: A conical strainer(2) is installed inside a filter body(1). A residual drain pipe(3) is connected to outside of the filter body(1) in the narrow direction of the cone. A residual drain valve(4) is connected at the end of the residual drain pipe(3). The residue inside the strainer(2) can be removed just by opening the valve(4). The residual drain valve(4) can be operated manually or automatically by detecting pressure difference at inlet and outlet of the filter.

Abstract: PURPOSE: A method for designing a profile of a roller is provided to determine an exact profile amount of a roller and to prevent the damage of the roller by reducing a contact pressure in the edge of the roller. CONSTITUTION: A method for designing a profile of a roller includes the steps of obtaining contact pressure distribution of the roller by elastic fluid lubrication analysis(S1), changing the contact pressure distribution of the roller to the corrected pressure distribution having no concentration of the contact pressure in the edge(S2), calculating elastic deformation amount of the roller based on the corrected pressure distribution(S3), and applying a profile amount at 20-230 % of the elastic deformation amount(S4).
