摘要： A process for producing a stator of dynamo-electric machine, wherein a coil end can be impregnated with a varnish in a simple manner at a high filling factor by regulating the viscosity of varnish at stator preheating temperature so as to fall within a given range. In particular, the process comprises a varnish treating procedure comprising a preheating step wherein a stator is preheated; a varnish application step wherein while rotating the preheated stator round the shaft center thereof, a varnish whose viscosity at stator temperature at the time of varnish application has been regulated so as to fall within the range of 16 to 105 mPa.s is dropped to a coil end in the direction of stator diameter from outside; and a varnish heat hardening step wherein the stator having the varnish applied thereto is heated to thereby harden the varnish. Thus, the stator having its coil ends impregnated with the varnish at a high filling factor so as to enhance the insulation and electrolytic corrosion resistance of coil ends and having the rigidity of stator whole body increased can be obtained.

摘要： PROBLEM TO BE SOLVED: To make it possible to eliminate coloration in the case of observation from a specified direction and to obtain good display quality by providing opposite electrodes with projecting parts, locally diminishing the distance between the electrodes and forming these portions as strong electric field regions. SOLUTION: When the projecting parts 3a, 3b are formed at the opposite electrodes 1a, 1b and voltage is impressed thereto, the electric field intensity of the regions of the electric fields 6a, 6b short in the inter-electrode distance is higher than that of the region of the electric fields 6c, 6d long in the inter-electrode distance. The liquid crystal molecules 2a existing in the strong electric field region rotate to change the alignment to the electric field 6a and the liquid crystal molecules 2b to change the alignment to the electric field 6b, respectively. The surrounding liquid crystal molecules are also dragged by these movements, by which the liquid crystal molecules 2c are rotated in the same direction as the direction of the liquid crystal molecules 2a and the liquid crystal molecules 2d are rotated in the same direction as the direction of the liquid crystal molecules 2b, respectively. Consequently, the rotating direction of the respective liquid crystal molecules may be changed in the region where the electric fields 6b, 6d are impressed and the regions where the electric fields 6a, 6c are impressed. As a result, the double refractivity of the liquid crystal molecules in both regions is eventually cancel with each other, by which the coloration at the time of observation from the specified direction is eliminated.

摘要： PROBLEM TO BE SOLVED: To adjust an angle of visibility in accordance with the purpose and the environment of use in the same liquid crystal display element by structuring it so that the angle of visibility is controlled by means of an electrode formed between the third electrode and at least either the first or the second electrode. SOLUTION: With a voltage applied between the first and the second comb- type electrode 1a, 1b and to the third comb type electrode 2, an electrical field is generated as shown by an equipotential line 5. The oriented direction of a liquid crystal molecule 3 becomes parallel to the electrical field, with the liquid crystal molecule 3 responding in a direction oblique against the surface of an electrode substrate. When the liquid crystal molecule 3 so responds, its optical contribution differs greatly against a change in the angle of visibility; therefore, the angle is narrowed down. In addition, when the voltage applied to the third comb type electrode 2 is made lower than the one applied to the first 1a, the inclination in the oriented direction becomes lower for the liquid crystal molecule at the time of responding, thereby enabling the wider angle of visibility.
