  • Patent number: 5380521
    Abstract: A deodorant containing deodorizing ingredients extracted from Oleaceae family plants obtained through a tissue culture by means of a medium with plant growth regulators as cytokinins and/or copper ions added for a highly efficient promotion of production of the deodorizing ingredients within cells of the Oleaceae family plants.

  • Patent number: 5240699
    Abstract: A deodorant consisting of deodorizing ingredients respectively extracted from plants and capable of performing deodorization with respect to a relatively wide range of odors, and performing as a whole the deodorization over a relatively wide range covering one or both sulfur and nitrogen compound odors. The plants are selected from a group consisting of Osmanthus, Forsythia, Paulownia, Syringa, Fartugium, Petasites, Loropetalum, Houttuynia, and Oxaslis.

  • Patent number: 4465539
    Abstract: A new artificial veneer resembling expensive natural wood veneers can be manufactured by a new method from an inexpensive raw log, wherein a wood-meal containing veneer is first obtained by slicing in quartersawn grain direction a primary artificial flitch of many material veneers of the inexpensive raw log stacked and bonded with a wood-meal layer interposed between them, and many of the wood-meal containing veneers are stacked and bonded, with the material veneers alternately interposed as they stand or as further processed, into a secondary curved artificial flitch, which is sliced in flatsawn grain direction into the new artificial veneers presenting a grain pattern similar to that of the expensive wood with minutely raised and recessed uneven surface at simulated porous zones by the wood-meal containing veneers.

  • Patent number: 4388133
    Abstract: A method of manufacturing artificial wood veneers comprises a step in which an artificial flitch formed of laminated material veneers respectively cut out of a certain kind of inexpensive natural wood is sliced in the direction of obtaining straight grain pattern to obtain a collected veneer in which mutual joining surfaces of the material veneers extend in parallel with each other and in the thickness direction, and a step in which many of the collected veneers thus obtained and material veneers cut out of another kind of natural wood are laminated, pressed and collected to form another artificial flitch which is sliced in a direction of obtaining a flat or flowered grain pattern which is very similar to that of a high grade natural wood.
