An ink head includes: a common ink chamber; a first nozzle including a first nozzle hole, a first flow channel and the common ink chamber, and a first actuator; and a second nozzle including a second nozzle hole, a second flow channel and the common ink chamber, and a second actuator, the second nozzle being adjacent to the first nozzle in a first direction. The first flow channel is linked to the common ink chamber via a first opening. The second flow channel is linked to the common ink chamber via a second opening. A center position of the first opening is shifted from a center position of the second opening in at least a third direction, the third direction crossing the first direction when viewed along a second direction, the second direction being from the common ink chamber toward the first flow channel.

According to one embodiment, a semiconductor device includes an insulating film. The insulating film includes a first insulating particle, and a second insulating particle. A particle size of at least one of the first insulating particle or the second insulating particle exceeds 0 nm and being not more than 30 nm. An average size of a void between the first insulating particle and the second insulating particle exceeds 0 nm and being not more than 10 nm.

Semiconductor device and method for manufacturing same

A method of applying an ink-repellent film includes flowing an inert gas to the interior of each of the nozzles in a nozzle plate from the rear surface to the front surface of the nozzle plate; applying a film of an ink-repellent material on the surface of the nozzle plate so as to form a film; and drying the film of the ink-repellent material.

Method of applying ink-repellent film and nozzle plate provided with ink-repellent film

A transparent drying agent includes a mixture of an alkoxide of the Group II, Group III or Group IV metal and a transparent organic polymer which is inert to and soluble with this metal alkoxide.

Transparent drying agent and organic electroluminescent device

An organic electroluminescent display device includes an array substrate, an organic EL element formed on the array substrate and having a transparent anode, a hole transporting layer, a light emitting layer, and a cathode, an epoxy resin layer so formed as to cover the organic EL element and containing 1 wt % or less of water, and a moisture-resistant layer formed on the epoxy resin layer.
