摘要:
An agitation apparatus (100) has a substantially cylindrically shaped agitation vessel (102); a rotation shaft (150) provided along the central axis of the agitation vessel (102); a substantially cylindrically shaped agitation member (104) having an outer diameter smaller than the inner diameter of the agitation vessel (102) and being fitted to the rotation shaft (150) so as to rotate concentrically with an inner circumferential surface of the agitation vessel (102); and a plurality of through holes (162, 164) formed through the agitation member (104) in radial directions of the agitation member. In the agitation apparatus (100), a gap between the inner circumferential surface of the agitation vessel (102) and the outer circumferential surface of the agitation member (104) is partially varied along a vertical direction of the agitation member (104). For example, the gap between the inner circumferential surface of the agitation vessel (102) and the outer circumferential surface of the agitation member (104) is wider at a lower portion (S2) of the agitation member (104) than at an upper portion (S1) of the agitation member (104).
摘要:
In the brazing of aluminum a flux composed of a mixture of alkali metal fluoaluminates, with or without admixed AlF.sub.3, is employed. The flux has a composition of AlF.sub.3 about 53-62%, KF about 35-44%, and LiF about 2-7%, in terms of simple compounds. The flux has a liquidus temperature in the range of 490.degree.-560.degree. C. depending on its actual composition. The flux is of particular utility when brazing aluminum containing 0.4-2% magnesium and/or having a low solidus temperature and is preferably employed in an atmosphere of a dry, inert gas.

摘要:
A two-step process for coating a surface of an aluminum article with zinc, wherein the surface is initially exposed to a zincate bath under relatively weak zinc-depositing conditions, and then further exposed to a zincate bath under stronger zinc-depositing conditions (lower ZnO concentration and/or higher temperature), to establish thereon an adherent coating of metallic zinc. The coated article may be heated to effect diffusion of the zinc into the aluminum for producing a zinc-enriched region adjacent the surface to protect the surface against corrosion.

The present invention relates to an electrode paste manufacturing system that includes, a twin screw extrusion mixer, a mohno pump that is connected at an inlet thereof to an outlet of the twin screw extrusion mixer, a deaerating tank that is connected to an outlet of the mohno pump, and a vacuum pump that is connected at an inlet thereof to the deaerating tank. The vacuum pump is configured such that a conduit system on the deaerating tank side of an airtight line formed at a contact portion between a rotor and a stator of the mohno pump is a closed system with the airtight line being a boundary.
摘要:
A method for producing a non-aqueous electrolyte secondary battery includes: subjecting a mixture of a negative-electrode active material on which oil has been adsorbed, CMC and water to hard kneading to prepare a primary kneaded mixture; diluting the primary kneaded mixture with water to prepare a slurry; and adding a binder to the slurry. The method further includes defining an amount of the oil to a value equal to or more than 50 ml/100 g and equal to or less than 62 ml/100 g, wherein the amount of the oil is an amount at the time when the viscosity characteristics of the negative-electrode active material exhibits 70% of the maximum torque that is generated when the oil is titrated onto the negative-electrode active material. The 1% aqueous solution viscosity of the CMC is defined to a value equal to or more than 6000 mPa·s and equal to or less than 8000 mPa·s.
