摘要： The present invention provides a liquid jet printing head, a method of manufacturing the same, and a liquid jet printing apparatus, which allow stable, high speed, and continuous printing. A liquid jet printing head provides an inflow of liquid from an inlet to a common chamber, then along with the surface of heating elements of a heating element substrate and with a wall of a housing to separate channels. Liquid drops will be ejected by heating the heating elements. Since liquid may flow linearly from the inlet to the separate channels in accordance with the present invention, smooth flow promotes evacuation of bubbles through a nozzle, while cooling the heating element substrate with liquid flowing along with the substrate. The present invention provides thereby stable printing with high speed, continuous ejection (printing) of liquid drops.

摘要： An ink jet recording head and a process for producing the same, and an ink jet recording apparatus are provided that improve the printing performance and also improve the production efficiency. A conjugated body 73 formed by conjugating silicon wafers 50 and 58 is cut, whereby nozzles 22 are opened, and cutting into head chip units is carried out. At this time, deep grooves 84 are formed on the surface of the silicon wafer 58 by anisotropic etching, and they are penetrated by etching on the opposite side. Grooves 90 are formed on the silicon wafer 50 by using the thus penetrated deep grooves 84 as a mask.

摘要： The present invention provides an ink jet recording head that enables stable high-speed continuous printing, its manufacturing method and an ink jet recording device. A bubble generated in a common liquid chamber is moved to the side of an ink tank via a communicating port formed in a sufficient size and a supply passage. That is, a bubble generated inside a common liquid chamber is exhausted satisfactorily from the common liquid chamber by forming the communicating port in a shape which the bubble can pass, resulting in the supply of ink to the common liquid chamber and an individual passage (nozzle) prevented from being blocked by the bubble. As a result, even if high-speed continuous jetting (printing) is performed, stable printing is enabled.

摘要： The present invention provides an ink jet recording head in which the degree of freedom in the design of the arranged position of an electric signal input-output terminal is enhanced, its manufacturing method and an ink jet recording device, the invention is characterized as follows. The ink jet recording head is formed by laminating a heater element substrate in which a heater element and others are arranged and a passage substrate in which nozzles and others are formed. When the nozzles and others are formed by etching in the passage substrate, a cut-out portion for exposing an electric signal input-output terminal of the heater element substrate is also formed. Therefore, the degree of freedom in the design of the shape and the position of the cut-out portion in the head chip is enhanced. It is possible to prevent a hydrophobic agent from adhering to the electric signal input-output terminal to result in electric connection failure if hydrophobic treatment is applied to a nozzle forming plane by forming the head chip so that the electric signal input-output terminal is not exposed at least on the side of the nozzle forming plane owing to the cut-out portion.

摘要： A satisfactory bonding is implemented at low cost. In a step, a resin layer is formed on a bonding surface side of a silicon wafer on which portion are formed electro-thermal transducers. In a later step, the silicon wafer and another silicon wafer are aligned and fixed temporarily, then the atmosphere is set at a pressure of 10−3 mbar or lower and the temperature is set at 300° C. or higher, and voltage is applied across the both wafers while pressure is applied to the wafers. When the value of an electric current flowing across the wafers has reached a level of a certain current value or lower, the application of the voltage is stopped and the atmosphere is opened to the atmospheric pressure while reducing the temperature.
