Latest Patents

Yamashita's recent inventions reflect significant advancements in their respective domains. His first patent introduces a novel polyester resin composition that exhibits excellent flame retardancy and melt thermal stability, along with remarkable laser markability. This polyester resin composition combines 3 to 60 parts by mass of a brominated polyacrylate flame retardant with 100 parts by mass of a thermoplastic polyester resin. Notably, the brominated polyacrylate flame retardant contains a sodium element concentration of 5 to 4000 ppm, as determined by X-Ray fluorescence analysis. The associated method for producing the resin involves washing the flame retardant with hot water at temperatures between 40°C and 100°C, followed by drying and mixing with the thermoplastic resin.

In addition, Yamashita developed an RF coil positioning device for MRI systems. This innovative device enhances the functionality of MRI technology by allowing a pallet of a bed unit to be accurately positioned at the center of a magnetostatic field. Key components include a coil detector that identifies the RF coil's passage through a designated reference point, an encoder that tracks the pallet's travel distance, and a control circuit that optimizes the drive of the motor to ensure precise alignment with the magnetostatic field.
