BASE FOR INK JET HEAD, INK JET HEAD USING SAID BASE, AND INK JET DEVICE EQUIPPED WITH SAID HEAD

Document Type and Number:

WIPO Patent Application WO/1993/002864

Kind Code:

A1

Abstract:

This invention provides an ink jet head equipped with an electrothermal transducer which is provided with an electrothermal resistor to generate, when electrified, heat energy to be utilized for jetting ink when directly supplied to the ink on a heating surface and disposed along the path of ink, wherein said electrothermal resistor is characterized by being composed of material containig at least Ir and one specific element or Ir and two specific elements at a specific composition ratio, the material being sufficiently durable even when the head is driven at comparatively wide driving pulses.
