Patent number: 5236960Abstract: The invention relates to water blown integral skin polyurethane foams made with a particular isocyanate quasi-prepolymer and resin side ingredients to yield a foam having good overall mechanical properties. The isocyanate quasi-prepolymer component of the present invention comprises from 0.5 weight percent to 30.0 weight percent or less uretonimine-carbodiimide-modified diphenylmethane diisocyanate, from 50 weight percent to 80 weight percent 4,4'-diphenylmethane diisocyanate and reacted with from 15 weight percent to 40 weight percent of a polyether polyol containing predominately secondary hydroxyl groups and having an average molecular weight from about 2,000 to 10,000, an average functionality from 1.5 to about 3.2, and a hydroxyl number from about 20 to 60, and optionally with a low molecular weight diol in an amount of from 1.0 weight percent to 10 weight percent, the weight percentages based on the weight of the quasi-prepolymer reactants.Type: GrantFiled: January 19, 1993Date of Patent: August 17, 1993Assignee: BASF CorporationInventors: Richard P. Harrison, Michael Scarpati, Thirumurti Narayan, Blair J. Zagata

Patent number: RE42248Abstract: A cleaning apparatus of organic substances attached to a vapor-deposition mask for low molecular weight organic EL devices comprises a first stage for treating a vapor-deposition mask with a derivative of pyrrolidone, a second stage for rinsing the vapor-deposition mask with water, and a third stage for rinsing the vapor-deposition mask with flowing water. The cleaning apparatus also comprises a fourth stage for treating the vapor-deposition mask with ethanol, a fifth stage for drying the vapor-deposition mask, and a carrying means that carries the vapor-deposition mask to each stage in sequence. It is desirable to adopt N-methyl-2-pyrrolidone as the derivative of pyrrolidone.Type: GrantFiled: March 26, 2009Date of Patent: March 29, 2011Assignee: Seiko Epson CorporationInventors: Toshiko Hosoda, Shinichi Yotsuya
