摘要:
A zipper tape is provided which can freely be used regardless of whether the zipper tape is made from a polypropylene-based resin or a polyethylene-based resin and also on which letters can be printed or any color can be given thereto. A method of producing the zipper tape with high productivity by means of extruding male strips and female strips in rows in a batch is provided. The zipper tape with the mating section formed thereon has a three-layered structure. The male strips and female strip for forming a mating section together are extruded from a miscellaneous extrusion molding machine onto a surface of the thermally fused film for forming a mating section in rows in the state where adjoining male and female strips form pairs respectively and are thermally fused and bonded to the base tape.

A zipper tape is provided which can freely be used regardless of whether the zipper tape is made from a polypropylene-based resin or a polyethylene-based resin and also on which letters can be printed or any color can be given thereto. A method of producing the zipper tape with high productivity by means of extruding male strips and female strips in rows in a batch is provided. The zipper tape (2) with the mating section (3) (the male strip (3a) and the female strip (3b)) formed thereon has a three-layered structure comprising the heat-insulating film (6) as an intermediate layer, the thermally fused film (7) thermally fused and bonded to one side of the heat-insulating film (6) of the bag (5), and the thermally fused film (8) for formation of a mating section bonded to another side of the bag (5). The male strips (3a) and female strip (3b) for forming a mating section together are extruded from the miscellaneous extrusion molding machine (101) onto a surface of the thermally fused film (8) for forming a mating section in rows in the state where adjoining male and female strips form pairs respectively and are thermally fused and bonded to the base tape. Then the base tape is cut along each strip with the adjoining male strip (3a) and female strip (3b) mated with each other to form the mating section (3), and is wound up to provide a product. Letters, marks, or colors are printed on or given to the mating sections (102) and (104) on the base tapes (101) and (103) respectively.

Described herein is a method of encapsulating a material to be processed by warm or hot isostatic pressing, and an apparatus suitable for practicing the method, which basically includes the steps of (a) enveloping a processing material in the form of loose or compacted powder with a metal foil of 30 .mu.m in thickness, and (b) welding overlying and underlying metal foil portions to encapsulate said material in said metal foil in sealed state.
摘要:
Synthetic zeolite is stabilized to water by soaking it in a buffered acid solution for a prolonged time. The stabilized synthetic zeolite does not exhibit alkalinity when it is dispersed in water at room temperature for 24 hours or more, and exhibits improved flowability and almost constant ratios among Na, Al and O along the depth direction from the surface of the zeolite particles.
摘要:
This invention relates to ion-exchanged fine cellulose particles, porous fine cellulose particles which can be advantageously used as an affinity carrier, and methods of production thereof. These fine particles of the invention have the advantage that they possess excellent pressure-resistant strength and can treat treatment liquors under pressure at a high flowing velocity. Thus, they can be advantageously used industrially in various separation and purification processes.

A pharmaceutical preparation for ameliorating nonulcer dyspepsia (NUD) or epigastric dysfunction complaints is provided. The present invention uses an aminobenzamide compound represented by the following formula (1) or a salt thereof: ##STR1## wherein each of R.sup.1 and R.sup.2 is independently a lower alkoxyl group; R.sup.3 is a hydrogen atom, a lower acyl group, a lower alkyl group, a lower alkoxycarbonyl group or a group represented by a formula --X--SO.sub.3 M where X is a lower alkylene group and M is an alkali metal or an alkaline earth metal; R.sup.4 is a hydrogen atom, a halogen atom or a lower alkoxyl group; R.sup.5 is an amino group, a morpholino group or a lower alkylamino group, where the alkyl moiety of the lower alkylamino group may have a hydroxyl group; and n is an integer of 1 to 6.
摘要:
A process for preparation of capsule for use in isostatic pressing treatment, the process comprising a first step of enclosing a material to be treated, such as ceramic, metal, resin, etc. with metallic foil having a thickness of from 30 to 300 .mu.m, and a second step of welding the metallic foil so as to seal the material to be treated in the metallic foil thus welded, thereby preparing a capsule, wherein the welding is carried out by means of TIG welding. Alternatively, the welding may be carried out by means of seam resistance welding. It is posible, by the process, to seal the material to be treated in a capsule easily and economically. The capsule thus obtained is in a good sealed condition, permits effective isostatic pressing treatment, and enables the treated material to be taken out easily. A ceramic or metal layer covers the material to be treated to prevent adhesion between the material and the metallic foil.
