Abstract: A bending and extending device 1 comprises an elastic hollow guide unit 2 and a movable part 3 to be movably inserted into the guide unit 2. The movable part 3 is constituted, either partially or entirely, of a plurality of belt-like flexible parts 30a and 30b, which extend in the axial direction of the guide unit 2 and the flexible parts 30a and 30b are connected at distal ends.

Abstract: A data analysis system (S) including a data analysis server (11), a data retention system (12) which retains data to be analyzed, and an analysis terminal (14). The data analysis server (11) sends to the data retention system (12), according to an analysis demand from the analysis terminal (14), an analysis request of the data based on a requirement to be satisfied by analysis of the data, and sends to the analysis terminal (14) an analysis result of the data based on the requirement received from the data retention system (12). The data retention system (12) analyzes the data based on the requirement according to the analysis request and sends an analysis result to the analysis terminal (14).

Abstract: An evaluating service system includes a random number generator for generating a random number for use in a simulation for predicting an operating rate of a facility, an operating rate simulation unit for predicting an operating rate, a device utilization effect calculation unit for calculating a device utilization effect from a predicted operating rate, a device utilization effect/income conversion unit for converting the device utilization effect to an income, an introduction/operation expense calculation unit for calculating costs generated by the introduction and operation of the device, a profit calculation unit for calculating a profit generated by the introduced device from the income and expense, a predicted profit storage unit for storing the result of at least two or more profit predictions, and a predicted profit display unit for displaying the result of an evaluation on a screen or printing the result for presentation.
