LIQUID DISCHARGE HEAD SUBSTRATE, LIQUID DISCHARGE HEAD, AND LIQUID DISCHARGE APPARATUS - A simplified explanation of the abstract

• This abstract for appeared for patent application number 18190406 Titled 'LIQUID DISCHARGE HEAD SUBSTRATE, LIQUID DISCHARGE HEAD, AND LIQUID DISCHARGE APPARATUS'

Simplified Explanation

The abstract describes a liquid discharge head substrate, which is a component used in devices that discharge liquid. The substrate includes several liquid discharge elements that are arranged in one direction on the surface of the substrate to discharge the liquid. There is also a liquid supply port on the substrate, which is located away from the liquid discharge elements in a different direction. This port supplies the liquid to the discharge elements. The substrate also has temperature detection elements that are used to measure the temperature. These elements are placed on the substrate and are connected to a driving wiring pattern. This wiring pattern extends in the same direction as the liquid supply port and reaches the edge of the substrate. It is used to drive the temperature detection elements and is connected to an external connection terminal. The wiring pattern is shared between the temperature detection elements.

Original Abstract Submitted

A liquid discharge head substrate includes a substrate, a plurality of liquid discharge elements, a liquid supply port, temperature detection elements, and a driving wiring pattern. The plurality of liquid discharge elements are arranged in a first direction on a major surface of the substrate to discharge a liquid. The liquid supply port is provided in the substrate and is spaced apart from the plurality of liquid discharge elements in a second direction crossing the first direction to supply the liquid to the plurality of liquid discharge elements. The temperature detection elements are arranged on the substrate to detect a temperature. The driving wiring pattern extends in the second direction to an end portion of the substrate to drive the temperature detection elements, is connected to an external connection terminal, and is shared between the temperature detection elements.
