摘要： An apparatus for ejecting droplets is provided with a ejecting head for discharging droplets, an electric circuit board having an electric circuit formed on a surface of the electric circuit board, the electric circuit being connected to the ejecting head, a holder for supporting the ejecting head and the electric circuit board, and a cover that overlaps the surface of the electric circuit board when the cover is fixed to the holder. The apparatus for ejecting droplets is further provided with a seal member that fills a gap formed between a peripheral region of the surface of the electric circuit board and an inner surface of the cover. The seal member effectively prevents droplets mist from penetrating to the electric circuit.

The mass matrix T′ is derived using finite-difference approximations at the discrete grid points so that the result of the matrix δTnum operating on a state vector corresponding to rotations or translations is 0, where T is a positive definite diagonal mass matrix and δTnum=T′−T.
