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 relates to a process of setting a concrete pile without noise or vibration which is thereby effective to decrease city noises. A concrete pile is sunk into a leading hole substantially concurrently with the progress of the excavation thereof. After the pile has been sunk through a desired distance, another supporting hole is excavated below the pile. A solidifying material, such as cement milk, mortar, or cement concrete including a cement expansion agent of calcium sulfoaluminate system or lime system, is poured into the supporting hole. The solidifying material is expanded within the supporting hole and permeates into the circumferential wall thereof, which is loosened by the excavation, so as to retighten the wall. Therefore, sufficient supporting force can be obtained.

A lithographic apparatus which performs drawing on a substrate with a charged-particle beam, includes an optical system having an aperture plate in which a first number of apertures are formed to pass a first number of charged-particle beams to perform the drawing, a substrate holder, a cleaning unit configured to clean the aperture plate, and a chamber containing the optical system and the substrate holder. The cleaning unit includes a case having an emitting hole plate in which a second number of emitting holes are formed, the second number being smaller than the first number, an active species source configured to generate active species in the case, and a driving mechanism configured to move the case.

A breather structure of an engine having a crank case and a cylinder fastened to an upper side of the crank case can improve the strength of a cylinder and can prevent an increase of weight of the engine. The breather structure is provided with a breather chamber integrally formed with the cylinder in an outer peripheral wall of the cylinder, and the breather chamber separates air including an oil mist within the crank case into an oil component and a gas component, returns the oil component into an oil reservoir of the engine, and discharges the gas component out of the crank case.

A method for manufacturing a semiconductor device is provided, in which the lengths of a wiring trench and a via hole in a depth direction are easily controlled. A component having a first insulating film is prepared on a substrate, and a layer is disposed on the above-described first insulating film. A mold having a pattern is imprinted on the above-described layer so as to form a second insulating film having a wiring trench and a first via, the pattern corresponding to the wiring trench and the first via. Thereafter, the above-described first insulating film is etched by using the above-described second insulating film as a mask so as to form a second via, which is connected to the first via, in the first insulating film.

A method of producing an electrode layer for a fuel cell, with which the electrode layer is produced by heating and drying an electrode paste (41) applied on a sheet-like base material (42). The method includes a process of heating the electrode paste from below the sheet-like base material. Vapor (74) produced above the electrode paste is removed by the heating to produce the electrode layer.
