Gas generation of a non-aqueous electrolyte battery having a negative active material that intercalates/deintercalates lithium ions at a potential not lower than 1.2 V relative to the potential of lithium as negative electrode is suppressed.A non-aqueous electrolyte battery comprising a non-aqueous electrolyte containing an electrolyte salt and a non-aqueous solvent, a positive electrode and a negative electrode is characterized in that the main active material of said negative electrode is an active material that intercalates/deintercalates lithium ions at a potential not lower than 1.2 V relative to the potential of lithium and the auxiliary active material of said negative electrode is an active material that at least intercalates lithium ions at a potential lower than 1.2 V relative to the potential of lithium and that there exists lithium showing a spin-lattice relaxation time (T1) of not less than 1 second as determined by a solid-state Li—NMR measurement in the main active material of said negative electrode. A method of manufacturing a non-aqueous electrolyte battery containing a non-aqueous electrolyte, a positive electrode and a negative electrode (a main active material and an auxiliary active material of the negative electrode) is characterized in that the negative electrode potential is lowered to not higher than 0.8 V relative to the potential of lithium at least once in the initial cycle.

A non-aqueous electrolyte battery suppresses gas generation in a non-aqueous electrolyte battery having a negative active material that intercalates and deintercalates lithium ions at a potential not lower than 1.2 V relative to the potential of lithium for the negative electrode thereof. The non-aqueous electrolyte battery comprises a non-aqueous electrolyte containing an electrolytic salt and a non-aqueous solvent, a positive electrode and a negative electrode having a negative active material that intercalates/deintercalates lithium ions at a potential not lower than 1.2 V relative to the potential of lithium and is characterized in that a film coat having a carbonate structure and a thickness of not less than 10 nm exists on the surface of said negative electrode and that the non-aqueous electrolyte battery is operated in a region of potential of the negative electrode higher than 0.8 V relative to the potential of lithium. A method of manufacturing a non-aqueous electrolyte battery having a non-aqueous electrolyte, a positive electrode and a negative electrode having a negative active material that intercalates/deintercalates lithium ions at a potential not lower than 1.2 V relative to the potential of lithium is characterized in that a film coat having a carbonate structure is brought into existence on the surface of said negative electrode by lowering the potential of the negative electrode to lower than 0.8 V relative to the potential of lithium at least once in an initial cycle.

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.

The present invention provides a generator cooling system of an engine which can supply sufficient cooling oil to a generator even during low speed operation, without complicating an oil passage formed within a wall of a crankcase. In the generator cooling system of the engine having a generator accommodated in a generator room which is formed at an end portion of the crankcase in a longitudinal direction of a crankshaft of the engine, the generator cooling system is provided with an oil passage formed to the crankcase in a position lower than an axis of the crankshaft, and an oil nozzle provided in the oil passage for injecting oil of the oil passage toward a lower portion within the generator room.

An electrode base material is held by electrostatic attraction when a voltage from a DC power source is applied to electrodes for electrostatic attraction. A paste is applied to the electrode base material, and then the paste is dried to form the water-repellent layer. Subsequently, another paste is applied to the water-repellent layer, and then the paste is dried. Accordingly, the substantially flat electrode catalyst layer including an extremely small number of depressions is formed. The electrode of the fuel cell produced as described above can be used as an anode or a cathode.

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.
