Method and device for calculating chassis height of a vehicle that has at least three air-suspended wheel axles. The resulting poly composition is suitable as a biocompatible material, such as a biomedical implant, implant coating material, tissue scaffold material, controlled release drug delivery vehicle, and cellular growth substrate. In the control device, the speed command signal generator changes an acceleration running curve in a deceleration interval in accordance with the moving direction and the load of the car of the elevator to generate the rotational speed command. The extension member is connectable to the base member such that the extension member extends from the base member. 0% or greater, which further improves the organoleptic properties of the milk. A drive nut is supported by the rotational-translational movement converter in an axially secure and rotatable fashion on the armature plate to assist the braking force.
