Title: Hitoshi Tokuyama: Innovator in Electric Compressor Technology
Introduction
Hitoshi Tokuyama is a notable inventor based in Sanda, Japan. He has made significant contributions to the field of electric compressor technology, holding 2 patents that showcase his innovative approach to engineering.
Latest Patents
One of his latest patents is for a "Dynamoelectric coil portion insulating construction." This invention involves a stator coil installed in a stator core, where an insulating resin is impregnated into the slot portions and hardened. The stator coil is made from enameled wires that have a polyamideimide resin layer applied radially outside a copper wire. The insulating resin primarily consists of a THEIC-modified polyester resin modified by a fatty acid.
Another significant patent is for a "Process for producing a hermetic electric compressor." This process is designed for a refrigerating or air-conditioning apparatus using a hydrofluorocarbon-based refrigerant. It includes a motor unit, a compressing unit driven by the motor unit, and a sealed housing that encloses both units while storing refrigeration oil at the bottom. The process utilizes a solventless varnish made from a thermosetting resin with at least two (meth)acryloyl groups, a low-viscosity vinyl or 1-alkylvinyl monomer, and an organic peroxide as a reaction initiator. This varnish serves as an insulating material for the magnet wires of the motor unit's stator and is cured by heating.
