Latest Patents

Uehara's latest patents include a piston and a method of producing the piston, as well as a pump that incorporates this piston. The piston is designed to be movably supported in a cylinder of a pump, allowing for reciprocal motion. It is constructed from a fluororesin material, which ensures that it remains unaffected by corrosive liquids. The cylindrical outer peripheral portion of the piston is flexible and has a thickness of 1 mm or less. This design features a flange portion at the open end, which is attached to the cylinder. When the pump operates, the piston rolls smoothly without causing deflections or bends, maintaining close contact with both the piston support member and the cylinder's inner face.

Another significant patent is the applicator device, which consists of a reservoir tank for trapping embrocation, a stage for holding a substrate, and a ferrule with a slit-shaped opening above the stage. The device includes a fluid transfer pump that guides the embrocation from the reservoir tank to the ferrule. It also features two opening and closing valves that manage the suction and discharge operations of the fluid transfer pump. The driving means allows for relative movement between the ferrule and the substrate when they are adjacent.
