Latest Patents

Yoshioka's latest patents include a method for producing organic microdisk structures. This method involves a cladding layer formation step where a cladding layer is created by printing a first ink containing a fluorine-containing hyperbranched polymer on a substrate using an inkjet method. The core layer formation step follows, where a core layer is formed by printing a second ink that contains a laser dye and a triazine-based hyperbranched polymer without fluorine on the cladding layer, also via an inkjet method. Finally, an etching step is performed, wherein the cladding layer is etched using a solvent that dissolves only the fluorine-containing hyperbranched polymer. This unconventional method provides a novel approach to producing organic microdisk structures using inkjet technology.

Another notable patent is for a light-induced fluorescent measuring device. This device incorporates a laser light source for emitting excitation light, a sample case, a photomultiplier tube, and a fluorescence collecting optical system, all embedded in a resin material that is transparent to both the excitation light and the emitted fluorescence. The resin material forms a housing that holds the essential components, ensuring efficient light path guidance for the fluorescence collecting optical system.
