A complex machine tool has a single frame having a chip, collecting space at a center portion thereof, first and second spindle stocks on the frame, relatively free to move and drive in a Z axis direction and holding the chip collecting space therebetween, workpiece spindles on the spindle stocks free to rotate and drive and facing each other, and tool rests. The tool rests have turrets and can assume various kinds of movement. Complicated and varied types of machining can be performed combining the rotation control of the workpiece spindles and the spindle stocks.

A method for producing a battery resulting from the joining with a plurality of weld nuggets therebetween of a foil layered part, at which foil exposed portions exposing an aluminum foil overlap, and a positive terminal member made of aluminum, includes: a formation step for forming at the foil layered part a foil welded part at which are formed, by welding aluminum foils together by means of ultrasonic welding, a first high-position part at at least a section of a surface to be joined, and a plurality of first low-position parts distributed at scattered points within the first high-position part; and a resistance-welding step for contacting the first high-position part to the positive terminal member, generating weld nuggets at the first low-position part by flowing an electric current, and resistance-welding the foil welded part and the positive terminal member with the weld nuggets therebetween.

A method of treating silicon powder-containing drainage water, comprising the steps of: including an inorganic flocculant composed of a silica sol-water-soluble metal salt having a molar ratio of silicon to metal of 0.05 to 3.0 into drainage water containing silicon powders to ensure that the metal concentration becomes 15 to 300 mg/L; and adding an organic polymer flocculant. In this method, the coagulation treatment of drainage water containing fine silicon powders can be carried out.

In a machine tool having plural coordinate systems and having controlled objects controlled on the basis of those coordinate systems, a coordinate system data memory storing dimensional information corresponding to each coordinate system as a coordinate system data is provided. A coordinate relation memory storing the coordinate position relation information by which the position relation among plural coordinate system is specified is also provided. If the controlled object corresponding to each coordinate system is driven, the coordinate system data is read from the coordinate system data memory when the coordinate system data belonging to the coordinate system except the coordinate system in which the controlled object is driven is needed. The read coordinate system data is converted from the coordinate system to which the corresponding coordinate system data belongs into the other coordinate system to which the controlled object belongs on the basis of the coordinate position relation information in the coordinate relation memory, and the controlled object is controlled on the basis of the converted coordinate system data.

A communication system includes a station-side terminal apparatus and multiple subscriber-side terminal apparatuses connected to the station-side terminal apparatus. The station-side terminal apparatus is configured to, in response to receipt of a packet from a subscriber-side terminal apparatus, a packet indicating whether data distribution is required, identify the subscriber-side terminal apparatus that has transmitted the packet, and transmit a packet indicating an address for which whether the transfer of distribution data is required is designated to the subscriber-side terminal apparatus based on whether data distribution is required. Each subscriber-side terminal apparatus is configured to, in response to receipt of a distribution packet, if the distribution packet has the address for which whether the transfer of distribution data is required is designated, transfer the distribution packet to host apparatuses accommodated thereto or prohibit the distribution packet from being transferred to the host apparatuses accommodated thereto.

In a process for treatment of powdery fumed silica, fumed silica to be discarded is collected by dispersing the fumed silica in water. Disclosed is a method for treatment of a fumed silica-containing wastewater collected in the process. The method comprises the steps of: adding an inorganic coagulant containing a metal to a fumed silica-containing wastewater in an amount of 15 to 300 mg/l. in terms of the metal, wherein the wastewater is either a wastewater containing fumed silica at a concentration of 0.05 to 3.0% by mass or a wastewater whose fumed silica content is adjusted to 0.05 to 3.0% by mass; and adding an organic polymeric coagulant to the mixture.

An apparatus for automatically changing a tool tip member for a robot includes a tip member changing jig disposed in an operational area of the robot. The tip member changing jig includes a base member, a rotating member supported by the base member so as to be rotatable about a rotation axis, and tip member holding means disposed at positions that are offset from the rotation axis of the rotating member. The tip member holding means holds the tool tip member so that a central axis of relative rotation, for threadedly mounting or demounting the tool tip member on or from the tool body, extends substantially parallel to the rotation axis of the rotating member and so that rotation of the tool tip member, with respect to the rotating member, is locked.
