Publication number: 20060025489Abstract: A flexible polyurethane foam is produced by blending a polyurethane raw material containing a polyol, a polyisocyanate, a blowing agent, and a catalyst with an inorganic compound hydrate having a specific gravity of 1.5 to 4.0 and reacting the above polyurethane raw material to effect foaming and curing. The inorganic compound hydrate is preferably an iron sulfate hydrate, a calcium sulfate hydrate, or a magnesium sulfate hydrate. The above inorganic compound hydrate preferably has decomposition temperature of from 100 to 170° C. Then, an increase in exothermic temperature owing to the above foaming and curing is diminished by evaporation of water formed through decomposition of the above inorganic compound hydrate.Type: ApplicationFiled: July 28, 2005Publication date: February 2, 2006Inventor: Tadashi Yano

Patent number: 6981943Abstract: Disclosed is a respiration leading system which can leads a living body to respire so that relaxation is effectively induced without any physiological load even if a respiration exercise feedback is not employed. This system comprises a control unit and a sense-stimulating unit. The control unit makes the sense-stimulating unit change the output energy for stimulating a sense of the living body so that the living body is induced to inhale and exhale as a physiological reaction. The energy change is done within the range of a respiration period x(sec) and a parameter y defined as 2 sec<x<12 sec and 0.85<y<1.45 (a region x?4 sec and y?1.3 is excluded). The parameter y is a ratio of exhaling time to inhaling time. The energy output in the first half period corresponding to either inhaling or exhaling and the energy output in the latter half corresponding to the other, induce the living body to respire.Type: GrantFiled: November 6, 2002Date of Patent: January 3, 2006Assignees: Matsushita Electric Works, Ltd., Matsushita Electric Industrial Co., Ltd.Inventors: Hiroki Noguchi, Manabu Inoue, Wataru Iwai, Hiromitsu Kobayashi, Katsushige Amano, Tadashi Yano, Yoshinori Tanabe
