Latest Patents
One of Yoshida's latest patents is the micro array chip, which is formed by high-speed injection molding. This chip features a body thickness of 1 mm, with each well having a capacity of 1.2 µL and a bottom wall thickness of 250 µm. Each well's opening is surrounded by an annular protrusion that rises 200 µm from the chip's surface. The openings can be sealed with a sheet of aluminum or resin, and the overall shape of the micro array chip is rectangular, allowing compatibility with flat plate heat blocks regardless of well specifications.
Another notable patent is the cylindrical multiple-pole mass filter with CVD-deposited electrode layers. This invention consists of a quadrupole mass filter made from an insulating material with a star-shaped cross-section. The inward bulges of this design are curved in a substantially hyperbolic manner. It features four electrode layers made from high melting point metal, which are deposited using a chemical vapor deposition (CVD) process. The quadrupole mass filter is designed with pre-rod electrodes, enhancing its functionality.
