Cermets are provided in which a substantially stoichiometric metal carbide ceramic phase along with a reprecipitated metal carbide phase, represented by the formula MxCy, is dispersed in a metal binder phase. The flux shield has an aperture. Consequently, the capacities of the drum and the tub are increased as compared with the case that the stator and the rotor are mounted at the rear of the tub, and therefore, washing capacity of the washing machine is greatly increased. The outer edges of the first filter membrane, the second filter membrane, the first support member and the second support member are liquid tight fixed to each other. The second touch block is disposed within the region surrounded by the first touch blocks and has an extending block passing through a gap between the first touch blocks and extending to the edge of the display region. The two-element f-\u03b8 lens corrects the nonlinear relationship between scanned angle and the time into the linear relationship between the image spot distances and the time.
