摘要： In some embodiments, an electrical device can include a body having a shape that extends along a longitudinal direction, and a set of electrodes implemented on the body at different locations along the longitudinal direction and configured to allow the electrical device to be positioned and mounted to a surface. The set of electrodes can include first and second electrodes configured to provide first and second engagements with the surface, respectively, and to allow a settling motion when the electrical device is positioned on the surface. The set of electrodes can further include a selected electrode having a side configured to allow the settling motion and an engagement portion configured to stop the settling motion and thereby provide a third engagement with the surface.

摘要： Disclosed is droplet ejecting apparatus that ejects droplets of a functional liquid onto a workpiece to draw a pattern. The droplet ejecting apparatus includes: a workpiece table; a droplet ejecting head configured to eject the droplets onto the workpiece placed on the workpiece table; a movement mechanism configured to relatively move the workpiece table and the droplet ejecting head in a main scanning direction and a sub-scanning direction; and a control unit configured to: detect a position of the workpiece or a position of the workpiece table while relatively moving the workpiece table and the droplet ejecting head along a plurality of scanning lines extending in the main scanning direction and set side by side in the sub-scanning direction; and create, based on a detection result, a correction table that indicates a correlation between a position of the movement mechanism and a positional correction amount of the workpiece table.
