Abstract:
An object of the present invention is to provide a stamper for transferring fine pattern and a method for manufacturing the stamper, the stamper has a fine structure layer to improve a continuous transferring property of the resinous stamper, and to allow accurate and continuous transferring. In order to achieve the above object, the present invention provides a stamper for transferring fine pattern, including: a fine structure layer on a supporting substrate, in which the fine structure layer is a polymer of a resinous compound whose principal component is silsesquioxane derivative having a plurality of polymerizable functional groups.
Abstract:
A production process includes providing an envelope and a mould, introducing the material to be moulded in the mould, placing the mould in the envelope, creating a low pressure in the envelope, and deforming the mould.
Abstract:
The invention relates to a device for moulding mixtures, preferably concrete mixtures for producing blocks. The device comprises a mould for receiving the concrete mixture, a table, to which the mould is coupled by means of brace elements, a vibration generation system, mounted on the table, for generating harmonic vibrations and for transmitting the latter to the table, a load in the form of a ram for exerting a force on the concrete mixture, first spring elements for elastically supporting the table and second spring elements for elastically supporting the load. A device of this type is equipped with at least eight rotating unbalanced shafts with parallel rotational axes in the vibration generation system. The unbalanced shafts are coupled in pairs for their rotational motion, each pair of unbalanced shafts having a common rotational axis and being driven independently of the other pairs.
Abstract:
A cementitious product slab useful in construction is made by: A. PREPARING A FLOWABLE AQUEOUS CEMENTITIOUS SLURRY, B. FORMING A SELECTED QUANTITY OF THE SLURRY INTO SLAB SHAPE, SAID FORMING STEP INCLUDING VIBRATING SAID SLURRY QUANTITY TO AID SLAB SHAPE FORMATION, C. PRESSURIZING THE FORMED SLAB TO SQUEEZE WATER THEREFROM, AND D. CURING THE RESULTANT SLAB.
Abstract:
A JARRING DEVICE FOR PRODUCING MOLDED BODIES WHICH IS PROVIDED WITH A JARRING TABLE ON TOP OF WHICH IS ATTACHED A MOLD BOX INTO WHICH THE MATERIAL TO BE MOLDED IS INTRODUCED. A COVER WEIGHT EXTENDS FROM ABOVE INTO THE MOLD BOX TO REST ON THE MOLDING MATERIAL THEREIN. A GUIDE ROD EXTENDS VERTICALLY UPWARDLY FROM THE CENTER OF THE COVER WEIGHT AND EXTENDS WITH ITS UPPER END SLIDABLY THROUGH A SPHERICAL GUIDE MEMBER WHICH IS PIVOTALLY SUPPORTED IN A SPHERICAL BEARING.
Abstract:
The invention relates to a lid (1) for placement on a container, said lid comprising a top wall (2), a circumferential wall (3) extending downwardly from said top wall, said circumferential wall ending in a flange (4), said flange comprising a circumferential wall part (5) extending outwardly from said circumferential wall for resting on an upper rim of said container and a circumferential locking wall (6) extending downwardly from said wall part for encircling the upper rim of said container, said locking wall comprising at least two solid notches (7) for snappingly attaching said lid around said upper rim of said container, and wherein said lid is made from hot-pressed moulded fibre material.
Abstract:
A method for the manufacture of cored construction products from dry particulate materials including feeding the materials into a vibrating mould so as to bring the same into pre-compacted condition, and subjecting the materials when in such condition to a transverse pressure so as to effect final compaction thereof. After compaction, a free standing surface of the material is impregnated with a setting liquid. The vibration is of such frequency and amplitude as to bring the individual particles into substantially uniform closely spaced disposition, the subsequent application of pressure bringing the material into a compacted state without any substantial re-arrangement or crushing of the particles.
