摘要： A magnetic head suspension includes a flexure portion, a load bend portion, a load beam portion, and a base portion. The load beam portion includes: a base end area continuously connected with the load bend portion; an intermediate area extending from the base end area toward a tip end side, and a tip end area extending from the intermediate area toward the tip end side to reach the magnetic head mount area. The base end area has first side edges tilted so as to gradually approach a central longitudinal axis line of the magnetic head suspension as the first side edges go toward the tip end side. The intermediate area has second side edges continuously connected with the first side edges and configured to be substantially parallel with the central longitudinal axis line or to be tilted to gradually approach the central longitudinal axis line as the second side edges go toward the tip end side.

摘要： A method for preparing a novel compound, i.e. a resinous material, characterized in that an epoxy compound is allowed to react with ammonium salt or a metal salt (for example, lithium salt, sodium salt, potassium salt, magnesium salt, etc.) of polyglutamic acid. The resulting reaction product is useful in a method for treating shaped materials especially polyester textiles. In this method the shaped materials are treated with the novel resinous material to improve the appearance and handling characteristics thereof. A process for providing a wooly finish on polyester textiles is characterized by treating textiles (including polyester knittings and mixed spun fabrics or knittings or mixed woven fabrics or knittings) in a bath of an emulsified mixed solution of an epoxy compound and a metal salt of polyglutamic acid containing a catalyst, and carrying out a heat-treatment of the resulted textiles after pre-drying.
