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.

摘要： In a magnetic head suspension, a piezoelectric element is disposed within a supporting part's open section so that at least a part of its distal-side end surface faces a distal-side wall surface of the supporting part's distal end section forming a distal-side gap between the distal-side end surface and the distal-side wall surface and at least a part of its proximal-side end surface faces a proximal-side wall surface of the supporting part's proximal end section forming a proximal-side gap between the proximal-side end surface and the proximal-side wall surface in a state where the piezoelectric element's upper and lower electrode layers do not face the supporting part and any rigid members that are fixed to the supporting part. The piezoelectric element is fixed to the supporting part by a distal-side insulative adhesive agent and a proximal-side insulative adhesive agent.

摘要： A load bending part includes a pair of first elastic plate parts and a second elastic plate part. The pair of first elastic plate parts are elastically deformed in a bended manner so as to generate a first pressing load. The second elastic plate part is positioned between the pair of first elastic plate parts in the suspension widthwise direction in a state of having both ends in its longitudinal direction connected to a pair of support pieces of a supporting part, and are elastically deformed in a twisted manner around a twist axis line along the suspension widthwise direction so as to generate a second pressing load. The total of the first and second pressing loads functions as a load for pressing the magnetic head slider toward the disk surface against air pressure due to rotation of a disk surface.

摘要： A magnetic head suspension of the present invention includes a flexure having a magnetic head mounting region, a load beam connected to the flexure and having a dimple at a portion corresponding to the magnetic head mounting region a load-bent portion generating a load for pressing a magnetic head to a magnetic disk via the load beam, and a base portion connected to a rear region of the load-bent portion. The load beam has a reinforcing structure that is symmetrical as viewed from the above based on a center longitudinal axis line, only in a center region in a longitudinal direction from a rearmost portion at the rear region to the dimple.
