  • Patent number: 9434007
    Abstract: A machine tool includes a table, a spindle head, a spindle, and an internal turning attachment. The internal turning attachment includes an attachment base, a body, and a tool holder. The tool holder has a tool mount surface to which a turning tool is detachably mounted. The tool mount surface provides a changeable tool mount angle with respect to a plane perpendicular to a spindle rotational axis in a state where the internal turning attachment is mounted to the spindle head. An angle between the spindle rotational axis and a vertical axis is to be larger than zero degree according to the changeable tool mount angle and is fixed while the turning tool contacts a workpiece in a case where the workpiece has a hole with a depth exceeding a length from a body upper portion to a tip end of the turning tool along the spindle rotational axis.

  • Patent number: 7201546
    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.

  • Patent number: 7198496
    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.

  • Patent number: 6527931
    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.
