Latest Patents
One of Sarai's latest patents is a method of producing a metal mold. This method involves using a heat-resistant sheet that is brought into close contact with a product configuration surface of a matrix, such as a wooden pattern or resin model, utilizing negative pressure. The matrix is then brought into contact with a melt of a low melting-point alloy while maintaining this close contact, allowing the melt to cool and cast one part of the mold. The matrix is subsequently removed, and the cast part is used as a new matrix to create a counterpart of the mold. Another significant patent is a washing liquid injection device for the rear window glass of a vehicle. This device features a pair of washing liquid injection nozzles arranged on a window molding that covers the lower periphery of the rear window glass. A washing liquid conduit is positioned under the window molding, with a portion of the washing liquid feed passage formed in a molding retainer that secures the window molding to the rear window glass.
