Abstract: The object of the present invention is to promote adequate body tissue formation action in a body tissue filling material. The present invention provides a graft material for body tissue regeneration 1 provided with a tubular member 2 composed of a material that allows nutrients B to permeate to the outside from blood A that passes therein, a body tissue filling material 3 arranged around the periphery of the tubular member 2, and a film 4 composed of a biocompatible material that covers them.

Abstract: A resin composition containing 100 parts by weight of a mixture containing 20 to 70% by weight of a polyphenylene ether which is modified with an unsaturated carboxylic acid compound having an ethylenic double bond and a carboxyl group or an acid anhydride group in a molecule and 30 to 80% by weight of a polyamide which contains 100 parts by weight of 6,6-nylon and 10 to 100 parts by weight of 6-nylon, 0.1 to 3 parts by weight of a metal salt of montanic acid, and optionally 5 to 70 parts by weight of polypropylene per 100 parts by weight of the modified polyphenylene ether in the mixture, which composition is suitable for the production of automobile relay boxes.

Abstract: This invention relates to a filling grease composition for automobile wire harness connector which comprises a petroleum oil having an initial boiling point of 400.degree. C. or more and a gelling agent having the general formula: ##STR1## wherein R is a divalent aromatic group represented by a member: ##STR2## as essential components, and the content of said gelling agent ranging from 5 to 50% by weight on the basis of the whole composition.

Abstract: A method and apparatus for discriminating aggregation patterns includes detection of an image of the aggregation pattern and dividing the image into a plurality of image line data using a photoelectric element. The image line data defines an image waveform and includes a maximum image value. High and low image levels are defined based on the maximum image value. These high and low image levels are used to determine first and second areas of the aggregation pattern image, which first and second areas respectively include image values at least as large as the high and low image levels. An area difference between the first and second areas and a level difference between the high and low image levels are then calculated, along with a ratio of the area difference to the level difference. The calculated area difference and ratio are then compared with a predetermined reference value to discriminate whether or not the aggregation pattern is positive.

Abstract: The aggregation pattern of particles is determined by obtaining luminous intensity curves representative of the particle aggregation pattern, obtaining a first threshold face by cutting the curves with a plane positioned at a first given height, obtaining a second threshold face by cutting the curves with a plane positioned at a second given height and determining the particle aggregation pattern by calculating the ratio of the area of the first threshold face to the area of the second threshold face.

Abstract: Thermoplastic polyester compositions comprising at least two groups of polybutylene terephthalate with substantially different intrinsic viscosity values and conventional additives for molding having an improved thermal flow capability under molding conditions expressed in such indices as heat flow (m cal/sec), enthalphy change .DELTA.Hm(Joule/gr) at the solidification of fused polymer, crystalline fraction (Xc), and the time of growth to (sec) of the primary nuclei of embryonic crystalline. The polymer compositions of the present invention result in a larger size of crystalline than the case of independent, single polymer and this enables to carry out injection moulding at about 20 degrees lower cylinder temperature than usual molding practice without sacrificing mechanical and thermal properties of the product.
