Abstract
This paper reports the recent progress in the ideal fabrics project that started in 1996. The aim of this project is to initiate the engineered manufacturing of “ideal fabric”. Ideal fabric is the fabric which satisfies the three conditions, good hand, good appearance of suit, and mechanical comfort for wear. The objective evaluation method of these three properties has been developed, and these objective method and fabric mechanics theories are fully applied to this project. Some ideal fabrics have been manufactured as the guideline for manufacturing ideal fabrics in the future. These trial fabrics are now being commercialized to assess the response of consumers.

Abstract
Describes the use of welding robots for making bridge panels. The system uses a total of 14 sets of High Speed Rotating Arc welding robots and newly‐developed arc sensor techniques are used with both joint end and bead end sensors. A teaching‐less direct CADCAM system was developed to control the robots. The welding robot system is now in commercial operation with welding efficiencies that are twice those possible with conventional processes.
