摘要:
A microwave oven includes a heating chamber, a plurality of cooking utensils detachably disposed in the heating chamber selectively in accordance with the cooking contents, a plurality of heat sources heating food placed on or contained in the cooking utensil and including a magnetron, an oven heater and a grill heater, optical sensors determining the cooking utensil disposed in the heating chamber, and a microcomputer. The cooking utensils include a glass dish, thawing gridiron, pot, upper and lower top plates, one-legged top plate, and gridiron. A microwave cooking mode is selected when the determination of the optical sensors indicates that neither upper nor lower top plate is present in the heating chamber. A heater cooking mode is selected when either upper or top plate is present. When the heater cooking mode is selected on the basis of presence of the upper top plate, either an oven mode or a grill mode is selected depending upon presence or absence of the gridiron. One of the heat sources in accordance with the selected cooking mode is controlled on the basis of a cooking program of the selected cooking mode by the microcomputer.
摘要:
A very effective method is proposed for the shrink-proof treatment of a fabric material of keratinous fibers, e.g., wool, in which the fabric material is first soaked with an aqueous solution of a persulfate compound followed by drying to effect surface oxidation of the fibers and then finished with a curable organopolysiloxane composition. Preferably, the curable organopolysiloxane composition comprises, as a dispersion in an aqueous medium, (A) an organopolysiloxane having hydroxyl or alkoxyl groups, (B) silica or an organopolysilsesquioxane in a finely divided form, (C) an alkoxy silane having an amido group and a carboxyl group in a molecule, (D) an alkoxy silane having an amino group or an epoxy group in a molecule, and (E) a curing catalyst, each in a specified proportion.

摘要:
An organopolysiloxane containing at least one epoxy group is produced by heating a mixture of (a) an epoxy group-containing organosiloxane; (b) an organosiloxane lacking an epoxy group and optionally containing an arkenyl group; (c) an aprotic polar organic solvent; and (d) a basic catalyst, until reaction between (a) and (b) by a disproportionation equilibration reaction occurs.

The invention concerns a novel process for the preparation of poly(N-acylethyleneimine) grafted polysiloxanes comprising sulfo-esterifying all or part of alcoholic hydroxyl groups of a hydroxy containing polysiloxane and conducting, in said sulfo-esterification reaction mixture, ring-opening polymerization of a 2-oxazoline compound. The present process can afford the desired poly(N-acylethyleneimine) grafted polysiloxane in a higher reaction yield.
