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.

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.

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.

An exhaust gas recirculation type gas turbine apparatus includes a compressor for compressing air, a combustion chamber for burning fuel and compression air exhausted from the compressor, a gas turbine driven by exhaust gas from the combustion chamber, a recirculation path for recirculating a part of the exhaust gas to an intake of the compressor, a recirculation amount control unit for adjusting the amount of exhaust gas to be returned to the intake of the compressor corresponding to a change in load of the gas turbine, and a spray unit for introducing liquid droplets into the interior of the compressor in which mixing gas, consisting of gas turbine exhaust gas passing through the recirculation path and air, flows so as to vaporize the introduced liquid droplets appearing to flow in the compressor.

摘要:
A first reaction/adjustment tank has a lower portion containing a calcium carbonate mineral, an upper portion containing a calcium carbonate mineral and a plastic filler, and an air lift pump for circulating waste water from the lower portion to the upper portion. Exhaust gas is introduced into a space. A second reaction/adjustment tank has a lower portion containing a calcium carbonate mineral and charcoal, and an upper portion containing charcoal and a plastic filler. Waste water circulates sequentially through the lower and upper portions of the first reaction/adjustment tank, and the lower and upper portions of the second reaction/adjustment tank. Exhaust gas circulates sequentially through the upper portion of the first reaction/adjustment tank and the upper portion of the second reaction/adjustment tank.
