Abstract: In order to make it easy to change the size of a cam device in the course of press mold design, there is provided a cam device including: a cam holder; a cam slider; and a cam driver, wherein the cam devices are grouped depending on the basis of width dimensions in combination of hardness of a sliding contact surface of the cam holder and a sliding contact surface on the cam slider end, and hardness of a cam surface of the cam driver and a cam surface of the cam slider, and the design structures of the respective groups are determined in such a manner that the maximum process ability in a certain group among the groups is larger than the minimum process ability of an adjacent group having a larger width dimension, and smaller than the maximum process ability in an adjacent group having a smaller width dimension.

Abstract: Disclosed herein are a method and a system of specification processing whereby are input the design specifications of a system under development, the expert knowledge of the system addressing these specifications, and the expert knowledge of a particular field to which the system belongs. The design specifications are transformed into information in list image having feasibility and containing state transitions and transition conditions. The information in list image is then edited as model specifications formed by the basic commands for outputting graphical image information. Document information is output in accordance with the model specifications (instruction words) and the expert knowledge. When output, the document information has high levels of both formality and understandability. The transformed information in list image can be verified in text image or graphical image in accordance with the transition conditions.
