  • Patent number: 5990186
    Abstract: A polyurethane foam for a sealant is disclosed which is produced from a composition prepared by compounding reaction mixture comprising a polyisocyanate ingredient and a polyol ingredient with a given amount by weight of an ozone inhibitor ingredient. A sealant of a predetermined shape is obtained from the foam. The polyol ingredient may be one ordinarily used for producing soft polyurethane foams, but especially preferably comprises a polyester-polyether polyol having both an ester segment and an ether segment in the molecular chain. The foam has excellent resistance to ozone deterioration and hence retains a sufficient air permeability required of a sealant for practical use. Further, the foam suffers little decrease in tensile strength from the initial value because it also has excellent resistance to deterioration by moisture and heat, i.e., high hydrolytic stability.

  • Patent number: 5968418
    Abstract: The purpose of the present invention is to provide a conductive contact material, the contents of which do not generate soil on a charged body not only during initial use but also after repeated use. A conductive contact material consists of thermoset urethane material containing an antioxidant within a range from 0.1 to 0.3% by weight, and an inorganic ion electrically conducting agent with in a range form 0.01 to 2.00% by weight. After ozone exposure or the like, molecule chain scission of the base material and antioxidant leads generation of active monomers and origomers. However, the conductive contact material containing the above specified proportion of an antioxidant and an inorganic ion electrically conducting agent prevents generation of active monomers and origomers which are soiling source for a charged body. The conductive contact material also prevents antioxidant itself from being a soiling source.

  • Patent number: 5945200
    Abstract: A molded plastic product has a pad and a core. The pad is made of plastic foam and a skin that covers the surface and side face of the plastic foam. The core has a pad housing for accommodating the pad. A groove is formed partly or entirely along the side face of the skin. The plastic foam bonds the pad and core together. The groove prevents the plastic foam from leaking onto the surface of the skin and provides a function of firmly holding the skin.

  • Patent number: 5896823
    Abstract: In order to manufacture a head rest skin as a final product, a main portion (G) of the skin, which lacks a lower surface portion (K) of the skin, necessary to complete the head rest skin as the final product, is prepared first. Then, a lower surface opening peripheral edge (g) of the main portion (G) of the skin is turned up to expose a back surface of the skin, and a decorated surface (I) of the main portion (G) of the skin is folded into the turned up lower surface opening peripheral edge. A peripheral edge (k) of a lower surface portion (K) of the skin and the lower surface opening peripheral edge (g) of the main portion (G) of the skin are overlapped one upon another in such a manner that the decorated surfaces of these edges (g), (k) confront each other with the back surface (R) of the lower surface portion (K) of the skin facing outward, and the overlapped peripheral edge portions are thereafter joined.

  • Patent number: 5895613
    Abstract: A method of manufacturing a molded plastic product prepares a core and a skin. The core has a pad supporting face, a sidewall surrounding the supporting face, and a pad housing defined by the supporting face and sidewall. The skin has a side face to be fitted to the sidewall of the core. The method sets the core on an upper mold so that the pad supporting face is oriented toward a lower mold, and places the skin on the lower mold so that the back face of the skin is oriented toward the pad supporting face. The method closes the upper and lower molds and injects foam ingredients between the core and the skin. The foam ingredients is reacted and adheres to the skin to form the pad as well as to the pad housing, to thereby integrate them into one body. The method is characterized by arranging an elastic seal on the side face of the skin so that the side face of the skin is attached to the sidewall of the pad housing through the elastic seal by the pressure of the reacted foam ingredients.
