An automatic set-up system is provided for setting up on a pallet work to be machined by a flexible manufacturing system automatic machine tool. The pallet has a support plate and a jig plate which overlies the support plate on which the work is placed. The support plate, the jig plate and the work are sequentially conveyed by a convey unit on a setting table. The relative positions of the support plate and the jig plate, and of the jig plate and the work are usually held constant by the engagement of positioning recesses and positioning pins. Even if the position of the jig plate or the work conveyed by the convey unit deviates from a predetermined position, a float base and a support plate (the float base, the support plate, and the jig plate) are floated by means of air bearing pads. The horizontal movement of these components can be readily controlled, so that positioning pins can be easily fitted in the positioning recesses. A clamp is mounted on the jig plate by a setting robot; and the clamp is clamped by a nut runner so that the work is fixed to the pallet. The machined work and the pallet are automatically cleaned by a cleaner; and the clamp is removed from the work resting on the setting table. Finally, the work is removed from the pallet.

The present invention makes it possible to remove an organic solvent in an electrode paste and fix an ion-conductive component while maintaining a desired moisture content. Specifically, a sheet of carbon paper applied with the electrode paste is horizontally held in a tank which comprises a drying apparatus. Water in the tank is brought to the boil by the aid of a first heater. Accordingly, the organic solvent in the electrode paste is removed, and the ion-conductive component is fixed, while forcedly humidifying the carbon paper and the electrode paste with steam.

In a vehicle location detecting system having a self-contained type location detecting section for determining the accumulation type location data, a satellite navigation type location detecting section for determining the satellite type location data from satellite navigation data, a synthesizing section calculates synthetic location data from the accumulation type location data and the satellite navigation type location data. An on-road location determining section determines an on-road location of the vehicle in accordance with the synthetic location data and road map data stored in a road map memory. A display sectin displays the on-road location determined by the on-road location determining section.
