The present invention provides a thermoplastic polyester resin composition, which exhibits stable processability in extrusion molding, blow molding and calender molding, particularly in profile extrusion and extrusion molding of boards and pipes, by efficiently enhancing melt viscosity of thermoplastic polyester resin, and gives a molded article having favorable surface properties and excellent impact strength. By compounding (B) 0.1 to 50 parts by weight of a viscosity modifier for thermoplastic polyester resin comprising (a) 3 to 95% by weight of alkyl(meth)acrylate containing an epoxy group, (b) 5 to 97% by weight of another alkyl(meth)acrylate and (c) 0 to 92% by weight of another vinyl monomer copolymerizable therewith, and having weight average molecular weight of 1,000 to 400,000; and (C) 1 to 50 parts by weight of a core-shell graft polymer, based on (A) 100 parts by weight of thermoplastic polyester resin, stable processability is exhibited in extrusion molding and a molded article having favorable surface properties and excellent impact strength is obtained.
摘要:
There is provided a steam generator for a sustained supply, in a simple and easy way and without displacement, of steam that is as safe as in a steamed towel to the body skin or mucosa. The steam generator has a steam generation portion composed of a steam-generating composition containing a metal powder, a salt, and water, and an adhesive layer on the surface which is to be applied to the skin or mucosa. The steam-generating composition discharges steam as the metal powder is oxidized. In the steam generation portion, the steam-generating composition is held or sandwiched in a support so as to inhibit the movement of the steam-generating composition inside the steam generation portion, and the steam generation portion itself is formed into a sheet.

A fixed type constant velocity joint comprising an outer ring whose inner spherical surface is formed with a plurality of track grooves disposed at circumferentially equispaced intervals to extend axially toward an open end. An inner ring whose outer spherical surface is formed with a plurality of track grooves is paired with the track grooves of the outer ring disposed at circumferentially equispaced intervals to extend axially. A plurality of balls is interposed between the track grooves of the outer and inner rings to transmit torque. A cage is interposed between the inner spherical surface of the outer ring and outer spherical surface of the inner ring to hold the balls. The open-side groove bottom of each track groove of the outer ring is shaped as a taper linearly diameter-expanded toward the open end thereof.
摘要:
A thermoplastic resin composition comprises a thermoplastic resin (A) and graft copolymer particles (B) having a hollow rubber portion and graft chain, in which a volumetric proportion of hollow part in the hollow rubber portion of the graft copolymer particles is 1 to 70% by volume. The thermoplastic resin composition contains the thermoplastic resin and the graft copolymer particles in a weight ratio (A)/(B) of 2/98 to 100/1. The hollow part in the graft copolymer particle functions to further improve impact resistance.

This invention provides a blood typing training kit comprising a red blood cell model and an antiserum model with no use of human blood in experiments for blood agglutination and in learning of blood typing, the red blood cell model being an easily available granule which can be suspended in water such as agarose bead, Sepharose, cellulose, Sephadex, cellulofine, alginate, tamarind polysaccharide, gelatin, xanthan gum, etc. or the saccharide- or protein-bound form thereof and the antiserum model being lectin, boric acid-containing liquid or immunoglobulin G.
摘要:
Provided is an oil or fat composition including the following components (A) and (B): (A) a tetracyclic triterpene alcohol selected from the group consisting of 24-methylene cycloartanol and cyclobranol; and (B) an oil or fat containing diacylglycerol at 5 weight % or more.
摘要:
The change replenishment management system includes a coin roll storage (1), a coin change dispenser (3), and a POS register (5). A control unit (16) of the storage (1) detects the presence and the denomination of a coin roll in a storage section of each drawer (11, 12, 13) in accordance with an output signal generated from a detection system (18), and transmits the result of detection to the coin change dispenser (3). When loose coins obtained by unpacking removed coin rolls, which are removed from the storage (1), are introduced into an inlet (30), a control unit (36 or 50) of the change dispenser (3) or register (5) compares the denomination and the number of the loose coins, which are detected by identification unit (31), with the denomination and the number of the removed coin roll determined on the basis of the detection result transmitted from the storage (1), and judging the correspondence therebetween.
摘要:
A coin-roll storage 1 comprises a storage body 1a and a coin-roll drawer 11 (12, 13) having a plurality of coin-roll storage portions 14 provided therein, each coin-roll storage portion 14 being adapted for storing one coin roll therein. Each coin-roll storage portion 14 of the coin-roll drawer 11 (12, 13) is adapted for storing therein the coin roll of any denomination. A determination unit 16 is adapted for determining the denomination of each coin roll by detecting an outer diameter, an axial length and material of the coin roll.
