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: PCT No. PCT/JP82/00290 Sec. 371 Date Mar. 24, 1983 Sec. 102(e) Date Mar. 24, 1983 PCT Filed Jul. 27, 1982 PCT Pub. No. WO83/00404 PCT Pub. Date Feb. 3, 1983.When a polycrystal or pyroelectric crystal material is manufactured by deposition of pyroelectric crystal particles in a layer, a temperature change or gradient is applied to pyroelectric binding particles which are dispersed between a pair of opposing electrodes (13, 14), before said particles are deposited on one (13) of the electrodes, for forming a layer of pyroelectric binding particles on the electrode (13) with the pyroelectrical axes of the particles oriented in advance of deposition thereof. Such temperature change or gradient may be produced by vaporization of a liquid dispersion (12) of the pyroelectric binding articles near its surface with resultant cooling of the electrode (13) and in the near-by zone in such a manner that the liquid temperature is decreased as the crystal particles approach the electrode (13). As a result, apparent electrical dipoles are produced in the pyroelectric crystal particles, whereby the pyroelectrical axes are oriented in the same direction and polarity before the particles are affixed to the electrode (13).

Abstract: An electric motor comprising a stator assembly, a rotor assembly including rotor magnets, a detecting winding assembly and motor housing receiving and relatively positioning stator assembly, rotor assembly and detecting winding assembly. The stator assembly includes the stator windings, a control circuit substrate fixed relative to the stator windings so as to be positioned within the field of the rotor magnets. The stator assembly further including circuitry on the control circuit substrate for controlling driving current supplied to the stator windings and the control circuit which includes on the substrate a rotational position detector. The rotor assembly includes a shaft rotatably journalled in the stator assembly, a magnet casing secured to the shaft and within which rotor magnets are fixed and a detector magnet secured to the shaft. The detecting winding assembly being arranged in face-to-face relationship with the detector magnet for generating motor speed detecting signals by the rotation of the detector magnet. The circuitry controlling the driving current responds to the motor speed detecting signals and the detected rotational position of the rotor magnets.
