Disclosed is a new class of TPUs with improved properties, based on poly diol, using 10 to 55% hard segment concentration, and cured with a diisocyanate. The invention further provides processes to prepare said composite, a process to prepare said fibres, and shaped polymer products comprising said composite. The response signal is varied in dependence on a variation of a physical operating value of the assembly in accordance with a characteristic pattern, the wear characteristic is determined from the variation of the response signal and the wear state is evaluated using the wear characteristic. A remaining amount of coarsely pulverized powder in the recovery chamber 40, an oxygen-containing amount of the R-T-B-based sintered magnet is reduced, and magnetic properties are enhanced. The predetermined program is reapplied to the other program when, after the application of the predetermined program, the supply of power to the at least a portion of the information processing apparatus is terminated and then resumed, based on the reapplication necessity information. The guiding accessory includes a helically extending wall that forms a lumen within which the device conductor and guidewire extend.
