Title: Masakazu Takahashi: Innovator in Ink Jet Technology
Introduction
Masakazu Takahashi is a notable inventor based in Sanda, Japan. He has made significant contributions to the field of ink jet technology, holding 2 patents that showcase his innovative approach to printing solutions.
Latest Patents
Takahashi's latest patents include an "Apparatus and method for ink jet recording." This invention provides an ink jet printer that performs recording by discharging an ink drop onto a recording medium. The nozzle is connected to an ink channel that houses aqueous ink. The printer head can vary the dot size on the recording medium by changing the size of the drop discharged from the nozzle. The aqueous ink has a degree of surface tension change expressed by the relation .DELTA.S=(S.sub.1 -S.sub.3)/ S.sub.2 of 0.3 or less, where S.sub.2 is the surface tension at 25°C, with a value of 20 to 50 dynes/cm. S.sub.1 represents the surface tension at 5°C, and S.sub.3 is the surface tension at 40°C. Another significant patent is related to "Ink for ink-jet recording," which contains carbon black particles with a specific surface active hydrogen content, water, and polyethyleneimine or alkylene oxide adduct of acetylene glycol.
