  • Patent number: 5425937
    Abstract: Hair treatment compositions, hair damage protective agents and hair care products, each contain an active ingredient comprising an antibody which binds to human hair keratins which constitute intermediate-diameter filaments. This antibody can be produced efficiently and in a large quantities from the milk of a bovid animal immunized with said keratins. As this antibody binds to the hair specifically, it is effective in preventing the elution of proteins from the hair, imparting smoothness and flexibility to the hair, and improving the adaptability to combing and luster of the hair.

  • Patent number: 5345515
    Abstract: A method of inspecting cleanliness of top sliber. The method classifies detected defects into pillwise defects and vegetal defects by introducing roundness, slenderness, gradation, dispersion, area, shape, gradation ratio, and length discernment against image signals of inspected top slibers picked up by an image sensor. An apparatus for inspecting cleanliness of top sliders is utilized. The apparatus initially picks up an image of uniformly spread top slibers conveyed to the apparatus and then processes the image signal with an image processing unit provided therefor. The method involves classifying defects on the top sliber into pillwise defects and vegetal defects in the top sliber based on the generated image signal.

  • Patent number: 5342634
    Abstract: Described herein are method and apparatus for producing instantly cookable pasta including various kinds of pasta and Chinese and Japanese noodles, and an encased instantly cookable pasta produced by such method and apparatus. According to the invention, part of raw dough of a starting mixture, which contains wheat flour as a major component, is subjected to preliminary steam-cooking, and then mixed with the remaining uncooked part of the starting mixture. The resulting mixture is then processed through shaping, steam-cooking and drying stages to obtain instantly cookable pasta, enshrouding the instantly cookable pasta product in a water-permeable casing before shipment. Due to suppression of thermal degeneration of gluten, the instantly cookable pasta possesses favorable resiliency and is free of the smell inherent to raw wheat flour and cohesion of individual pasta cords.

  • Patent number: 5308697
    Abstract: A potentially elastic composite filament, preferably a core-sheath composite filament composed of a polyurethane as the core and a polyester as the sheath, wherein the ratio of a polyurethane component having allophanate cross-linkages to a linear polyester component readily soluble in water or an aqueous alkali solution ranges from 1/1 to 90/1 and the polyester component is exposed on the surface of the filament in its cross-section. Although the core component has a high tensile strength and a large elongation at break, these properties are controlled by the sheath component. Therefore, this filament can be formed into a textile structure with good workability similar to that of ordinary synthetic fibers, and the obtained structure develops characteristics as an elastic polyurethane filament when treated with water or alkali.

  • Patent number: 5281379
    Abstract: A process for manufacturing a thermoplastic resin composition by melt-kneading a thermoplastic resin and fine particles or an additive, includes: introducing gaseous and/or liquid fluid containing fine particles of at most 10 .mu.m particle diameter or an additive to an unmelted granular or molten thermoplastic resin moving bed; adhering or depositing the fine particles or additive onto said moving bed, while the fluid in the gaseous state is being discharged; and then successively melt-kneading a mixture of the granular resin with the fine particles or additive. This process can be combined with a subsequent shaping step continuously that follows. The process of the invention saves energy, raw materials and labor consumptions and yields shaped articles of high quality and uniformity.
