Abstract: A method for manufacturing rotary ball display devices wherein a plurality of such balls are provided with a coating of a color different from the remainder of the ball, the ball members are coated with a thin coating insoluble in the settling medium into which they are introduced, so that upon settling into a low viscosity liquid, they form a uniform layer. A high molecular weight hardenable coating material which is soluble in the low viscosity liquid is then poured onto the coated ball members to cover the layer. Then, the low viscosity liquid is removed and the hardenable coating material is caused to harden. The thin coating is then dissolved away from portions of the ball members to leave cavity portions thereabout into which a high resistivity liquid is introduced. The resulting ball members have a refractive index on the colored layer which is substantially the same as the refractive index of the high resistivity liquid contained in the cavities.

Abstract: A dew-sensing hygroscopic element includes a pair of electrodes and a dew-sensing hygroscopic material arranged between the electrodes which detects dew by the change of impedance between the electrodes. The dew-sensing hygroscopic material comprises polyvinyl alcohol having a saponification equivalent of 20 to 65 as a base material and contains an organic electrolyte.
