Abstract: Provided are a wind tunnel balance calibrator capable of improving accuracy of attitude control of a wind tunnel balance, and a wind tunnel balance calibrator which can ensure a wide work space around the wind tunnel balance. A wind tunnel balance calibrator includes a load application mechanism for applying a load to a wind tunnel balance and an attitude restoration mechanism for restoring an attitude of the wind tunnel balance. The attitude restoration mechanism is constituted by a parallel-link mechanism including a support plate for supporting the wind tunnel balance, and actuators capable of displacing the attitude of the support plate with six degrees of freedom.

Abstract: To make to possible for any one to create a color system by mixing materials based on a geometric progression as well as to arrange colors quickly by computer-based expression method. To provide a systematic color arrangement and production method according to a geometric progression and matrix ( computer-based numeric value table). As the color material is mixed, you may indicate the unit of mixture as 1. That is, it is expressed by numeric values by making length 1×width 1×height 1. The feature is that you can create a color system by mixing it in a method of geometric progression ratio=½ and that you can express the colors in computer display by putting systematic determinant values.

Abstract: A novel polyester composition which can give shaped articles being free from warping and having superior mechanical and thermal properties. The polyester composition comprises (A) 100 parts by weight of an aromatic polyester, (B) 5 to 150 parts by weight of flat glass flakes, and based on the total weight of (A) and (B), (C) 0.01 to 10% by weight of an epoxy compound containing two epoxy groups, and optionally (D) 0.01 to 5% by weight of a phosphorus compound and/or (E) 0.5 to 50% by weight of a rubbery elastomer selected from the group consisting of copolymers containing 30 to 90% of an acrylic ester as a constituent monomer and poly(ether.ester) elastomers. Up to half of the flat glass flakes may be replaced by a powdery inorganic solid such as feldspar.

Abstract: A fire-resistant thermoplastic polyester resin composition having excellent anti-dripping properties which comprises(A) an aromatic polyester resin,(B) a graft copolymer of a butadiene polymer-vinyl monomer in an amount of at least 0.5 parts by weight but less than 25 parts by weight per 100 parts by weight of said polyester resin (A),(c) a fire retardant in an amount of from 0.5 to 35 parts by weight per 100 parts by weight of said polyester resin (A).

Abstract: A fire-retardant thermoplastic polyester resin composition free from "dripping" comprising(A) 100 parts by weight of an aromatic polyester resin,(B) from 0.5 to 100 parts by weight of an alkaline earth metal carbonate, and(C) from 0.5 to 50 parts by weight of a fire retardant.
