  • Patent number: 9254661
    Abstract: 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.

  • Patent number: 9150014
    Abstract: A printer and a method of printing by depositing liquid droplets (26) onto a substrate (12), wherein a line is printed in a printing direction (B), wherein the droplets (26) forming the line are continuously printed wet-on-wet, and wherein, at least in a middle part of said line, the droplets (26) are printed according to a regular droplet pattern, and wherein, at least in one end part of the line, at least an outermost droplet (26) of the line is printed deviating from the regular droplet pattern, thereby adapting the continuously wet-on-wet printed line for compensating for ink flow behavior which causes deviation from the image to be printed.
