A load-detecting deviceincludes a load detection sensor unit SU and a baseon which the load detection sensor unit SU is mounted, and the load detection sensor unit SU includes an upper surfaceS configured to be pressed by a seat cushion SC, a first electrode, and a second electrode. The upper surfaceS moves with respect to the mount surfaceS such that an angle of the upper surfaceS with respect to the mount surfaceS changes.

A heat insulated tank is disclosed having inner and outer walls between which a supporting material is interposed. The material comprises a molding of alkaline earth metal silicates or a molding of composite material based thereon having a continuous open cell structure and subjected to heat treatment under vacuum. Inside and outside faces of said supporting material are provided with a suitable number of grooves. The entire surface of said supporting material is impregnated with a solution of sodium silicate, potassium silicate or ethyl silicate and subjected to baking. The supporting material has a high insulating capability and a high resistance to compression, thus it is applicable to square shaped tanks in addition to conventional spherical or cylindrical ones. The tank is easy to manufacture with increased storage capacity.
