Title: Electrical insulation coil and rotating machine therewith
Inventor: AKATSUKA MASAKI
IPC: H02K3/34
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To improve thermal conductivity and breakdown voltage by insulating a conductor with a filler charged layer which involves filler including spherical filler, and thermosetting resin, and an insulating layer on which a mica layer including mica is laminated. SOLUTION: A filler charged layer includes filler at which spherical filler is mixed and thermosetting resin, and a mica layer includes mica and, if necessary, reinforcing material and thermosetting resin. A mica insulating layer 5 is formed by laminating a filler charged layer 2 and a mica layer 3 alternately from a conductor subjected to a strand-to-strand insulating process. In an electrical insulation coil, filler of prescribed sphere is included in the filler. As a result, the viscosity of the filler charged layer degrades, and the breakdown voltage of the electrical insulation coil is restrained from lowering. The filler causes the insulation layer to have high thermal conductivity, thus it is possible to improve the heat dissipation of the electrical insulation coil.

Title: Method for coating paper and plate and coat-coloring agent
Inventor: RUTANEN ANNE
IPC: D21H23/30
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To make it possible to coat a web by using a mixture containing a polymer at a comparatively low temperature and at an appropriately low viscosity by using as a thickener in a coat-coloring agent a polymer whose viscosity increases, when a temperature rises. SOLUTION: In a method for coating a cellulose web on the surface of which a water coat-coloring agent is applied, the water coat-coloring agent containing an aqueous polymer whose viscosity increases, when a temperature rises in an aqueous solution, is used. In addition, a coating temperature is increased after the coat-coloring agent is applied, to gel the polymer. For gelling, a methyl cellulose whose gelling temperature is about 5-10 deg.C higher than the use temperature thereof, or appropriate polymer is preferably used. The temperature of the coat rises after the application of the coat-coloring agent to cause gelling of the polymer. Consequently, the coat-coloring agent is rapidly coagulated and thereby, the amount of the mixture to be recycled is quantitatively decreased.  Further, the formation of mist is reduced in a film press process, and the coat by the conventional blade coating is improved.
