Title: Norihiro Yoshinari: Innovator in Liquid Ejecting Technology
Introduction
Norihiro Yoshinari is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of liquid ejecting technology, holding a total of 15 patents. His work focuses on enhancing the efficiency and stability of liquid ejecting heads, which are crucial components in various printing and dispensing applications.
Latest Patents
Yoshinari's latest patents include innovative designs for liquid ejecting heads, cleaning methods, and liquid ejecting apparatuses. One of his notable inventions is a liquid ejecting head that maintains stable ejecting operations without causing kogation. This invention features a liquid chamber that includes a first electrode covering a heating resistor, a second electrode positioned differently from the first, and a third electrode. When the heating resistor is activated, a voltage is applied between the first and second electrodes to ensure that the first electrode matches the polarity of a predetermined liquid component, while the second electrode has the opposite polarity. Additionally, when the heating resistor is inactive, a voltage is applied between the second and third electrodes to maintain the same polarity for the second electrode as the predetermined component.
Another significant patent involves a control method for a liquid ejecting head that utilizes first and second heat-generating resistors to produce thermal energy for liquid ejection. This method includes a first covering portion that protects the first heat-generating resistor and a second covering portion that is electrically connected to the first and covers the second heat-generating resistor. An insulating layer is placed between the heat-generating resistors and their respective covering portions. The surface potentials of the covering portions are set to be equal to or less than ground potential when no drive voltage is applied, ensuring efficient operation when the drive voltage is activated.
