摘要： A robot control system has a portable operating device TP and a robot control device RC. The portable operating device TP is actuated by a rechargeable secondary battery and used to operate a robot R. The robot control device RC is capable of wireless communication with the portable operating device TP and performs automatic operation of the robot R based on teaching data provided by the portable operating device TP. The robot control system causes an emergency stop of the robot R when the wireless communication between the portable operating device TP and the robot control device RC is interrupted. The robot control system further includes a charging device CU, a connection monitoring section 12, and an automatic operation continuing section 11. The charging device CU charges the secondary battery by electrically connecting the portable operating device TP to the robot control device RC.

摘要： The invention provides a retardation-controlling optical member that includes a retardation layer obtained by aligning and fixing crosslinkable liquid crystal molecules and columnar structures disposed on the retardation layer. When a liquid crystal cell is formed by use of the retardation-controlling optical member, the columnar structures are effectively inhibited from subsiding in the retardation layer to locally make the cell gap smaller even when pressure is externally applied in a thickness direction of the liquid crystal cell. A sum total of lower bottom areas of columnar structures disposed on a retardation layer is made larger sufficiently compared to a total area of, in particular, an effective display region of a retardation layer surface where the columnar structures are disposed, whereby pressure applied from a thickness direction is dispersed.

摘要： An optical filter including at least a coloring matter layer that includes a coloring matter having an absorption maximum wavelength in a wavelength region of 800 to 1100 nm and a coloring matter having an absorption maximum in a wavelength region of 570 to 610 nm contained in an identical layer. The coloring matter layer does not substantially contain two or more ionic coloring matter compounds different from each other in cation part. The optical filter can be disposed on the viewing side of a display. By virtue of the above construction, the optical filter and display, even when a plurality of coloring matters are present as a mixture in an identical coloring matter layer, can realize suppression of interaction between coloring matters and do not cause any change in spectral characteristics even under use for a long period of time.
