A ferroelectric thin film is produced on a substrate placed in an oxygen gas atmosphere within a reaction chamber. Evaporated source materials (organic metal compounds) are separately introduced in a predetermined sequence into the reaction chamber to produce a PZT or PLZT layer structure having an estimated stoichiometric composition. This cycle of introduction of the source materials is repeated continuously to produce a PZT or PLZT ferroelectric thin film having a predetermined number of PZT or PLZT layer structures piled on the substrate.

Method for ferroelectric thin film production

A double link type front suspension system for an automotive vehicle of the front engine front drive type or the four wheel drive type is comprised of upper and lower control arms for swingable connecting a knuckle for rotatably supporting a front wheel to a vehicle body. A curved extension bracket is provided to rotatably connect the knuckle upper section with the upper control arm. The extension member is movably connected at its upper end section with the outboard end section of the upper control arm and rotatably connected at its lower end section with the knuckle upper section. The relative rotation between the extension member and the knuckle upper section is made around a straight line (steering) axis) passing through a ball joint for connecting the knuckle lower section and the lower control arm, thereby making it possible to set the steering axis regardless of the upper control arm.
