摘要:
A liquid droplet ejecting apparatus of the present invention includes a cleaning unit, a regular flushing unit, capping unit, and an ejection-amount measuring unit as droplet ejecting head maintenance units used for function maintenance, function recovery, adjustment, or inspection of a liquid ejecting head. The droplet ejecting head maintenance units are arranged in a group in a movable platen as a maintenance-unit installing section. The movable platen is supported by an accessory stand physically separated from a main body.
摘要:
A liquid droplet ejection apparatus performs a drawing operation on a workpiece set on a set table by driving the ejection of a functional liquid droplet ejection head in a head unit while moving the head unit in a main scanning direction relative to the set table. The liquid droplet ejection apparatus includes an ejection defect test unit for inspecting an ejection defect of the functional liquid droplet ejection head. The ejection defect test unit includes a drawn unit on which a predetermined test pattern is drawn by test ejection from the functional liquid droplet ejection head and ejection-defect determination means for determining the ejection defect by capturing an image of the test pattern drawn on the ejection-defect test unit and recognizing the image. The drawn unit is disposed on a scan moving axis offset from the set table towards the main scanning direction.
摘要:
A convex polycrystalline silicon film is formed on a handle wafer. A semiconductor layer is formed on the polycrystalline silicon film. The semiconductor is thinner on its areas in which the convex polycrystalline silicon film is formed and is thicker on its areas in which the convex polycrystalline silicon film is not formed. An opening is formed in each of those areas of an insulating film which are located under respective thick-film semiconductor areas of the semiconductor layer. The polycrystalline silicon film is formed in the openings to connect electrically the thick-film semiconductor areas and the handle wafer together.

摘要:
Oxygen content in the exhaust gas of a combustion system is controlled such that the actually detected value of the oxygen content is compared with a set value which is varied in accordance with the combustion load of the system. A value theoretically adapted to control an air-fuel mixing ratio is calculated from the combustion load and the result of the comparison, and the flow rates of air and fuel supplied to the combustion system are controlled according to this value.
