Abstract: A dense interconnector film is formed over a fuel electrode, while preventing calcium included in material for the interconnector from solid phase reaction with zirconia included in material for the fuel electrode. When forming the interconnector film 5 made of lanthanum chromite-based perovskite type oxide which includes calcium in its composition includes calcium to the fuel electrode 2 of which composition includes zirconia, a intermediate layer 6 is formed on the fuel electrode 2, by using (Sr0.9La0.1)(Ti0.9Nb0.1)O3, and then onto the intermediate layer 6, the interconnector film 5 is formed.

Abstract: When a rotary table rotates, a main control section of a multi-tasking machine detects vibration of the rotary table on which a workpiece is mounted based on fluctuation of a position droop computed by a servo system. The main control section computes the arrangement position (the eccentricity amount and the eccentricity angle) of the workpiece with respect to the rotary table based on, for example, the detected vibration, the weight of the workpiece, and the rotation speed of the rotary table. The main control section computes the attachment position of a balancer with respect to the rotary table based on the computed arrangement position of the workpiece. Therefore, a suitable attachment position of a vibration suppressing balancer with respect to the rotary table is easily obtained.

Abstract: A lever type connector includes a housing having recessed rail members with first and second locking recesses. A lever pivotable between an initial position and a final position is mounted on the housing so that the lever is either pushed over toward a first side or a second side of the housing in the initial position. A wire cover has sliding claws that are received in the recessed rail members to slideably mount the wire cover to the housing. The sliding claws have locking projections that engage either the first projections on the first side of the housing or the second projections on the second side of the housing to lock the wire cover to the housing. A lock preventing member is arranged between the first locking recesses and the second locking recesses and prevents the wire cover from being locked to the housing in an incorrect orientation.

Abstract: An amino acid-N,N-diacetic acid (AADA) or its salt with an equivalent or less of an alkali metal is produced by reducing, through electrodialysis, alkali metal ions from an aqueous solution of the alkali metal salt of an AADA. By this configuration, an AADA salt can be produced in a much higher yield than conventional equivalents without requiring a regeneration operation of a resin as in the use of an ion exchange resin or without requiring crystallization-separation of crystals of the AADA salt as in the addition of an organic solvent. A salt of an amino acid-N,N-diacetic acid is also produced by reacting an AADA with any of metal oxides, metal hydroxides, metal carbonates, metal hydrogencarbonates, ammonium hydroxide, ammonium carbonate, ammonium hydrogencarbonate or organic amine compounds. By this configuration, a metal salt, aromonium salt or organic amine salt of an AADA can be produced with efficiency without the formation of by-products.

Abstract: Detergent compositions comprising aminodicarboxylic acid-N,N-dialkanoic acid or its salt (component A) and a synthetic surface active agent having microbial degradability (component B).In particular, in the case where an alkali salt of polyoxyalkylene alkylether acetic acid or alkyl polyglycoside is used as the surface active agent (component B), the detergent compositions exhibit excellent washing effect without forming metallic soap even in washing water with high hardness, and also show high solubility even under the condition of low water temperature, and have excellent microbial degradability. Thus, the detergent compositions are particularly suitable for washing fabrics. Further, in the case where synthetic anionic and/or nonionic surface active agent is used as the surface active agent (component B), influence of corrosion to light metals is small.
