  • Publication number: 20030215474
    Abstract: Spherical composite particles are formed of inorganic fine particles and resin fine particles joined together, and an average particle diameter is in the range from 1.1 to 100 &mgr;m, in which the average particle diameter of the inorganic fine particles is in the range from 5 to 600 nm and the average particle diameter of the resin fine particles is in the range from 10 to 500 nm. The inorganic fine particle and the resin fine particle have almost the same size, and the hardness, softness, and adaptability when spreading on a skin can finely be adjusted as desired in a wide range according to the contact feeling required for the cosmetics in which the particles are blended.

  • Publication number: 20030171475
    Abstract: The resin-coated scale-like inorganic particles have soft feel, adhesivity to human skin and effective in suppressing excessive luster. The scale-like inorganic particles are those with the surface coated with resin, and are characterized in that the 100% modulus of the resin in the tensile test is in a rage from 50 to 3000 N/cm2. The resin is preferably one or more selected from the group consisting of polyurethane, a styrene-butadiene copolymer, an acrylonitrile-butadiene copolymer, a silicone-based elastomer, and a polyolefin-based elastomer. The resin-coated scale-like inorganic particles are blended in the cosmetics according to the present invention.

  • Patent number: 6562323
    Abstract: A composite powder prepared by coating a ramentaceous substrate with at least two color layers. A difference between the maximum value and the minimum value of the ab hue angle hab (hmax−hmin) as defined in the recommendation on uniform color space by CIE is in the range from 10° to 180°. A ratio of the maximum value vs the minimum value of the brightness L* as defined in the recommendation is in the range from 1.0 to 2.0. According to the viewing angle, the color tone of the composite powder changes.

  • Patent number: 6482419
    Abstract: An inorganic composite powder is formed of a scaled substrate, and at least three inorganic oxide layers having different refractive indexes respectively and sequentially laminated in an order of high refractive index to low refractive index from a surface of the scaled substrate to an utmost outer layer. A refractive index of an inorganic oxide used for forming the utmost outer layer is 1.73 or less, and a difference in the refractive indexes between the utmost layer and a layer adjacent thereto is 0.6 or less. Alternatively, the thickness of at least one of a second or higher inorganic oxide layer is within ±20% of a value d given by an equation: d=(&lgr;×X/4)/n, wherein &lgr; indicates a wavelength of visual light, X indicates an odd integer, and n indicates the refractive index of the inorganic oxide.

  • Publication number: 20020037262
    Abstract: White or colored pigments which do not suffer from color tone or hiding performances thereof even when the surface is moistened with water or oil, without spoiling coloring performance or hiding performance of the pigments themselves. These pigments are surface-coated with an inorganic compound having the refractive index of 1.8 or below. The inorganic compound is preferably silicon oxide, and the pigments are preferably inorganic pigments comprising titanium oxide, zinc oxide, or iron oxide. The cosmetics of the invention are blended the pigments therein.

  • Patent number: 6184604
    Abstract: A brake mechanism includes a reduction gear train, a motor structure, and a braking means. The reduction gear train transmits at least a rotation force in a first rotational direction supplied from a drive source. The reduction gear train is imparted with a returning tendency in a second rotational direction opposite to the first rotational direction. The motor structure has an output shaft rotatably connected to the reduction gear train. The braking means has field magnets, an armature coil, a braking circuit, and either one of a fixed resistor, a variable resistor, a rectifying diode, a Zener diode, a varister, a constant-current diode, a light-emitting diode, and a lamp bulb.
