Title: Innovations by Atsushi Hirano
Introduction
Atsushi Hirano is a notable inventor based in Ohmihachiman, Japan. He has made significant contributions to the field of ceramics, particularly in the development of advanced ceramic materials and devices. With a total of 3 patents to his name, Hirano's work has had a considerable impact on the industry.
Latest Patents
Hirano's latest patents include a ceramic slurry composition, a positive characteristic thermistor device, and ceramic molding techniques. The ceramic slurry composition he developed reduces the content of organic binders, allowing for quicker heating and removal while minimizing shrinkage during baking. This composition consists of a ceramic powder and an organic vehicle that includes an aqueous solvent and a polyurethane resin with an average particle diameter of about 300 nm or less. The organic vehicle is in an emulsion state, where fine particles of the polyurethane resin are dispersed in the aqueous solvent.
His positive characteristic thermistor device features a main body made of semiconductor ceramic material that delaminates cleanly when excessive voltage is applied. This device has outer layers with lower porosity on both sides of an inner layer with higher porosity, which is created by burning a ceramic material mixed with resin beads. When an overvoltage is applied, the inner layer delaminates, resulting in an open circuit.
