Abstract: A robot system includes a robot, and an information processing portion. The information processing portion is configured to obtain a learned model by learning first force information about a force applied by a worker to a workpiece, first position information about a position of a first portion of the worker, and first workpiece information about a state of the workpiece, and control the robot on a basis of output data of the learned model.

Abstract: A titanium dioxide photocatalyst carrier is prepared by coating a surface of a substrate with a titanium dioxide precursor solution prepared from a hydrolyzable titanium compound and an aromatic compound solvent, and then heat-treating the coated substrate thereby preparing a carrier coated with a thin layer of titanium oxide.

Abstract: It is intended to provide a titanium dioxide photocatalyst carrier which exhibits a high photocatalytic activity and which has, as a surface layer, titanium dioxide excellent in abrasion resistance, and a process for its production.

Abstract: An anode for generating available chlorine from seawater by electrolysis which comprises a substrate made of titanium or an alloy thereof, and a coating on said substrate which is made up of an active anode material layer containing 15-85 wt % of platinum, 5-35 wt % of iridium dioxide, and 10-15 wt % of ruthenium dioxide. The anode has greatly improved anode performance such as current efficiency, cell voltage, and durability. Therefor, its use for a long period of time becomes possible in any condition of seawater.

Abstract: An anode coated with .beta.-lead dioxide which comprises a titanium substrate, titanium expanded metal welded on at least one side of the titanium substrate, titanium reinforcing bars welded on the peripheries of said expanded metal to both said expanded metal and said substrate, at least one intermediate layer being applied on said substrate and said expanded metal, said intermediate layer consisting either of an alloy or an oxide of platinum group metals; and a .beta.-lead dioxide coating layer on said intermediate layer.The anode of this invention has particularly good dimensional stability and provides excellent adhesion of the .beta.-lead dioxide coating layer to the substrate, and hence is highly suitable for the electrolytic production of chlorates, perchlorates, and periodates, and furthermore it is also useful as an insoluble anode in electroplating and in electrolytic treatment of waste water.

Abstract: An insoluble anode for generating oxygen which comprises a substrate made of titanium or an alloy thereof, a first coating on said substrate which is made of metallic bismuth or bismuth oxides, and a second coating on said first coating which is made of metallic iridium and iridium dioxide, has greatly improved durability and permits use for a long period of time.
