摘要:
The present invention relates to a process for printing characters or image with high durability on a fibrous sheet by a dry method, fabrics prepared by said printing process, and an apparatus for preparing said fabrics. The present invention relates to a process for preparing an information-bearing fibrous sheet, comprising the steps of temporarily forming an image such as characters or identification mark on a fibrous sheet by a dye; heating it to let the dye migrate into the fibrous sheet; and pressing another sheet material to the fibrous sheet with the image temporarily formed, with heat treatment for removing the excessive dye. The process of the present invention does not include the step of washing by water and allows dyeing with a sense of OA apparatuses. Therefore, it can be widely applied for clothing, and industrial and fashion fabric goods, etc. and expected to tempt the development of quite new applications.

Zn alloy particles for high corrosion resistance rust prevention paint containing, by mass %, Mg: 0.01 to 30% and having a balance of Zn and unavoidable impurities, having physical fracture facets and/or cracks of a length of 0.01 μm or more or cracks of a depth of 0.01 μm or more, having an average particle size of 0.05 to 200 μm, and having an aspect ratio of maximum size and minimum size (maximum size/minimum size) of an average value of 1 to 1.5. Also, a high corrosion resistance rust prevention paint containing these Zn alloy particles and a high corrosion resistance steel material and steel structure coated with that paint.

摘要:
The shape of each electrical supply die for contact-supplying electricity to a wire electrode is changed to a cylindrical shape, and grooves are provided in its outer surface in parallel to the traveling direction of the wire, wherein upper electric supply is effected by contact-supplying of electricity at a projecting surface formed between adjacent ones of the grooves, while lower electric supply is effected by pressure contact-supplying of electricity by causing a concave surface to contact the groove.

A wire electric discharge machining apparatus comprises a tank having an opening at its one side surface, which is movable in a two-dimensional plane, a shielding body having a through hole, which is in slide-contact with the side surface having the opening of the tank so as to close the opening, an arm which has first and second ends, at least one of which is fixed to a machine body and the other is extended into the tank through the through hole and the opening, and which supports in the tank a wire guide for guiding a wire electrode to a workpiece placed in the tank, an enclosure member capable of expansion and contraction in response to a relative movement of the tank to the arm, the enclosure member having both ends sealingly connected to the circumferential portion of the through hole of the shielding body and the machine body respectively, and a working liquid supplying device for supplying a working liquid to the tank through a space formed between the arm and the enclosure member.
摘要:
A sealing structure for use in a wire cut electric discharge machining apparatus for machining a workpiece in a machining solution, the machining apparatus having a machining reservoir for storing the machining solution which has a through window in a horizontal direction at side wall thereof to allow an arm for guiding a wire electrode to move in horizontal direction, the sealing structure prevents the machining solution from leaking. The sealing structure allows the arm to move smoothly in X and Y direction relative to the machining reservoir. The sealing structure comprises a covering plate for covering the through window of the reservoir, sealing member disposed between the covering plate and the reservoir, holding portion for holding the covering plate movably relative to the reservoir. The holding member includes plural bearings and an extendable bellows for surrounding the arm to prevent the machining solution from leaking.
摘要:
Artificial leather and a dyeing method therefor; the leather includes ultrafine polyamide fibers and is particularly a grained artificial leather having bright, deep color, good color fastness to dry cleaning with charged soap, a delicate touch free from any undesirable rubber-like feeling, as well as high durability.A super-entangled fiber base is provided comprising ultrafine polyamide fibers and/or bundles thereof; polyurethane including polyoxyethylene of molecular weight of 500-5,000 is applied. The polyamide ultrafine fibers are dyed with a metal-dye complex and a fixing agent.
