摘要： A liquid ejection head includes a plurality of ejection ports, a plurality of pressure chambers each communicating with each of the ejection ports, a piezoelectric actuator constituting part of walls of the pressure chambers, and a common liquid chamber containing liquid to be supplied to the pressure chambers. The pressure chambers and the common liquid chamber are opposed with an opposing wall interposed therebetween. The opposing wall faces the wall of the pressure chambers constituted by the piezoelectric actuator A reinforcing portion that supports the opposing wall is provided in the common liquid chamber.

摘要： Precise positioning of a film used to seal an electrical connection on a liquid ejecting head is made possible. Specifically, positioning is conducted in a state in which part of the film is held to a finger by suction. Next, the finger is moved downward while in the positioned state, and part of the film is pressed against a wiring board. With part of the film fixed to the wiring board in this way, a sealing resin flows while being covered by the film. Consequently, shifting of the position of the film as the sealing resin flows may be prevented. As a result, it becomes possible to conduct covering with the film in a precisely positioned state.

摘要： In order to efficiently produce a liquid containing ultrafine bubbles of a desired gas, an ultrafine bubble-containing liquid producing apparatus includes a gas dissolving unit that dissolves a predetermined gas into a liquid, and a UFB generating unit that generates ultrafine bubbles in the liquid in which the predetermined gas is dissolved. A CPU performs control under a first condition in a case of causing the gas dissolving unit to operate in a circulation route passing through the dissolving unit. The CPU performs control under a second condition different from the first condition in a case of causing the UFB generating unit to operate in a circulation route passing through the UFB generating unit.

摘要： An element substrate is bonded to a support substrate with high positional accuracy. A manufacturing method of the liquid ejecting head includes curing a first adhesive, which is in contact with an element substrate and a support substrate, at a first temperature to perform first temporary fixing, heating a second adhesive, which is in contact with the element substrate and the support substrate, to a second temperature higher than the first temperature so as to cure the second adhesive and perform second temporary fixing and heating a third adhesive, which is in contact with the element substrate and the support substrate, to a third temperature higher than the second temperature so as to cure the third adhesive and bond the element substrate to the support substrate. An elastic modulus of the second adhesive is larger than an elastic modulus of the first adhesive at the second temperature.

摘要： A manufacturing apparatus for a solidified matter of an ultra-fine bubble (UFB)-containing liquid includes: a UFB generating unit that generates the UFB-containing liquid; and a cooling unit that generates the solidified matter of the UFB-containing liquid by cooling the UFB-containing liquid. The cooling unit cools the ultra-fine bubble-containing liquid such that a first solidified portion and a second solidified portion at a lower ultra-fine bubble concentration than that of the first solidified portion are formed in the solidified matter.
