The present invention provides a drum type washing machine capable of adequately distributing the laundry articles along the inner circumferential wall of the drum at the start-up of the dehydrating operation with high probability, thereby reducing the start-up time of the dehydration. In an embodiment of the present invention, the drum is controlled to rotate at a constant speed 50 r.p.m. to agitate the laundry articles (Step S12), and the drum speed is almost continuously monitored. If the change in the speed does not exceed 1.5 r.p.m. for 0.5 second (Steps S13 through S16), the laundry articles are loosened and easy to distribute. Therefore, the drum speed is raised to 80 r.p.m. (Steps S17 and S18). If the eccentric load detected at this speed does not exceed a predetermined value (Steps S19 and S20), the laundry articles are adequately distributed along and pressed onto the inner circumferential wall of the drum. If a sudden change in the speed has been detected within a short period of time that is less than 36 milliseconds (Step S22), the laundry articles are tangled in a mass form. Therefore, the rotating direction of the drum is reversed, and the agitating direction is restarted in the opposite direction (Step S21).

The invention discloses a method for determining a cutter head thickness of a full face tunnel boring machine (TBM), belonging to the technical field of design of parts of a tunnel boring machine. According to the method for determining the cutter head thickness of the tunnel boring machine, the cutter head thickness is determined according to a theory of elastic mechanics by calculating deflection w(r, theta) of the TBM cutter head under the action of a transverse load q.
