  • Patent number: 6042608
    Abstract: A figure adjusting pad capable of permitting mold release to be readily carried out, being significantly improved in air-permeability, preventing a wearer from having an unpleasant feeling toward it when it is worn and eliminating ply separation with use. The figure adjusting pad includes a pad body including a foamed layer increased in air-permeability and arranged on a rear side thereof and a silicone gel layer arranged on a front side thereof which are laminated on each other. The pad also includes a cover sheet for covering an outer surface of the pad body, which includes a facing sheet for covering a front side of the pad body and a backing sheet for covering a rear side of the pad body. The facing sheet includes a knitted web increased in stretchability arranged on a front side thereof and a polyurethane film arranged on a rear side thereof and laminated on the knitted web.
    Type: Grant

  • Patent number: 5733335
    Abstract: A figure adjusting pad is capable of permitting mold release to be readily carried out and is significantly improved in air-permeability, thus preventing a wearer from having an unpleasant feeling toward it when it is worn, and eliminating ply separation with use. The figure adjusting pad includes a pad body including a foamed layer increased in air-permeability and arranged on a wrong side thereof and a silicone gel layer arranged on a right side thereof, which are laminated on each other. The pad also includes a cover sheet for covering an outer surface of the pad body, which includes a facing sheet for covering a front side of the pad body and a backing sheet for covering a rear side of the pad body. The facing sheet includes a knitted web increased in stretchability arranged on a front side thereof and a polyurethane film arranged on a rear side thereof and laminated on the knitted web.

  • Patent number: 4299947
    Abstract: A high-ortho phenolic novolac resin having excellent curability, heat stability and flowability can be produced safely at low cost by a process which comprises reacting a phenol and an aldehyde at a temperature of more than 100.degree. C. with (A) a catalyst effective for the addition reaction selected from the salts of divalent metals in combination with (B) a catalyst effective for the condensation reaction, or comprises reacting a phenol and an aldehyde under reflux in the presence of the catalyst (A), adding an acid to adjust the pH to 1-5, removing water under reduced pressure and then subjecting the product to reaction at a temperature of more than 100.degree. C. This process enables the addition reaction and the condensation reaction to proceed with a good balance, can solve problems arising in the prior process such as gelation, low yield and the like, and can produce a high-ortho type phenolic novolac resin safely at low cost. Accordingly, this process is quite advantageous in industry.

  • Patent number: 4297473
    Abstract: Disclosed herein is a novel high-ortho phenolic novolac resin having excellent quick-curing property and thermal stability for use as phenolic resin molding material and perfectly free of divalent metal salt which is detrimental to the electrical properties of the molding material. This resin can be obtained by condensing a phenol and an aldehyde in an aldehyde/phenol molar ratio ranging from 0.6 to 1.0 and at a reaction temperature of more than 100.degree. C. at which the selectivity for condensation at the para-position is lowered (that is, the probability of the condensation at the ortho-position increases), with a weakly acidic catalyst having a specified dissociation constant (pKa value). The high-ortho phenolic novolac resin (having the specific molecular weight and ortho/para linkage ratio) obtained from said reaction is very useful for industrial applications as a phenolic injection molding material or epoxy/phenolic low-pressure encapsulation molding material with excellent electrical properties.
