Patent number: 5780943Abstract: A stage apparatus has a pair of permanent-magnets fixed to a magnet holder and a coil fixed to a coil holder and positioned between the permanent-magnets. When electric current is supplied to the coil, an attractive force is generated between the coil and the upper permanent-magnet, while a repulsive force is generated between the coil and the lower permanent-magnet, thereby moving the coil holder in the vertical direction relative to the magnet holder. When the attractive force and repulsive force act on the coil simultaneously, the resultant force has high linearity with respect to the electric current because the attractive force and the repulsive force cancel the nonlinear characteristics of each other.Type: GrantFiled: April 2, 1997Date of Patent: July 14, 1998Assignee: Nikon CorporationInventor: Kazuya Ono
