Abstract: The present invention provides a low reflection glass plate which has an effect of reducing reflectance against light even at an incident angle of 60° sufficiently, in high yield. A process for producing a low reflection glass plate, characterized by the use of a treating fluid (1) comprising a resin B1, fine gold particles, an organic metal compound of at least one metal (M1) selected from the group consisting of iron, titanium and zirconium, and an organic solvent, and a treating fluid (2) comprising a film-forming compound, a resin B2 having the same thermal decomposition temperature as the resin B1 or a higher thermal decomposition temperature than the resin B1, wherein said process comprises applying the treating fluid (1) on the surface of a transparent glass substrate, followed by drying at a temperature of from 50 to 250° C. to remove the organic solvent, further applying the treating fluid (2), followed by drying at from 50 to 250° C.

Abstract: A rotor structure is to be provided which can diminish stress concentration in teeth-wedge fitting portions located near magnetic poles of a rotor in a rotary electric machine. Teeth 6 have slant faces for abutment against slant faces of wedges 8 to retain the wedges in a fitted state between adjacent teeth, the wedges 8 having slant faces each formed at a predetermined angle relative to the radial direction of a rotor 1, and a circular arc is formed at each slant face rising position in the teeth 6. In this case, the radius of the circular arc formed at each slant face rising position 12 in a preset number of teeth 6 located near magnetic pole portions 7 of the rotor 1 is set larger that of the circular arc formed in the remaining teeth.

Abstract: When molding reinforced fiber layers of a creepage block which is in contact with a field winding in a rotor of a rotary electric machine, a layer containing organic fibers made from polybenzoimidazole, polyparaphenylenebenzobisoxazole, aromatic polyamide, polyarylate, and aromatic polyester is integrally molded on that side of the creepage block which is for contact with a field winding. The rotor thus formed stabilizes a slippage between the field winding and the creepage block caused by thermal expansion of the field winding in the rotor during the operation and thereby minimizes the amount of bending of a rotor shaft.
