摘要:
Plural nozzle arrays of which each comprises plural nozzle holes (247a) from which ink is ejected are arranged slantingly in a main scanning direction. A distance between a first arbitrary nozzle hole (247a-1) and a second nozzle hole (247a-2), in a nozzle array adjacent to the array to which this first nozzle hole (247a-1) belongs, which is adjacent to the first nozzle hole (247a-1), and a distance between the first nozzle hole (247a-1) and a third nozzle hole (247a-3), in the nozzle array to which the second nozzle hole (247a-2) belongs, which is further adjacent to the first nozzle hole (247a-1) are different from each other.
摘要:
A method of producing a semiconductor device which can reliably perform conductor filling to form a through hole electrode by a simple method is provided. A method of producing a semiconductor device of the present invention includes the steps of thinning a substrate from its back side in a state in which a first supporting body is attached to the front side of the substrate, removing the first supporting body from the substrate and attaching a second supporting body having an opening to the back side of the substrate, forming a through hole communicating with the opening of the second supporting body in the substrate before or after attaching the second supporting body, forming an insulating film within the through hole, and filling a conductor into the through hole of the substrate.

摘要:
An ink jet recording apparatus, which performs printing by ink ejection, includes a pressure chamber in which ink liquid is filled; a nozzle hole (116) which is formed so as to communicate with the pressure chamber; a piezoelectric element (113) which is formed on the pressure chamber, and deforms the pressure chamber by mechanical expansion and contraction, whereby pressure is generated in the pressure chamber and ink is ejected from the nozzle hole (116); and a dew point control unit (123) which maintains a dew point in an atmosphere of the piezoelectric element (113) and the vicinity of the piezoelectric element at a lower value than a dew point in an environment where the ink jet recording apparatus is set. The dew point control unit (123) includes a compressor (123a), and an air drier (123b) which dries compression gas from the compressor (123a) and feeds it to the piezoelectric element.
