The expanded product of the present invention is an expanded product having a density of from 0.02 to 0.7 g/cm³, which is obtained by expanding ultra-high-molecular-weight polyethylene having a viscosity average molecular weight of from 300,000 to 10,000,000. This expanded product can be prepared by adding carbon dioxide to ultra-high-molecular-weight polyethylene in the molten state in an extruder, and expanding the resin by extrusion such that each of the surface temperature and the central part temperature of the resin immediately after discharge from the die may be a predetermined temperature, while at the same time setting the residence time and pressure of the resin at the die section to specific values. Based on these, the invention provides an expanded product with good external appearance, having a skin layer to which the functions such as light weight, insulating property, sound absorption, low dielectric constant, impact absorption, flexibility and the like can be imparted without significantly deteriorating the excellent features of abrasion resistance, self-lubrication, impact strength, cryogenic properties and chemical resistance that are inherent to ultra-high-molecular-weight polyethylene; and a process for preparation of the expanded product stably.

The present invention relates to a woven fabric structure including at least one array of warp yarns interwoven with at east one array of substantially orthogonally extending weft yarns, wherein each end of a warp yarn is extended beyond the last weft to form either a binder or a seam loop which can be interdigitated with similar seam loops of the opposing fabric end and joined by at least one pintle wire passed through a tunnel formed by the interdigitated seam loops. The inventive woven fabric structure is characterized in that the seam loops and the binders of the warp yarns possess a ratio above 1:1 and below 4:1.

The invention discloses a metal guide plate capable of improving screw-setting precision in a spinal operation and a manufacturing method of the metal guide plate. The manufacturing method mainly comprises steps as follows: target spine model data of a patient are extracted through segmentation editing processing on the basis of CT (computed tomography)/MRI (magnetic resonance imaging) scanned original data about the spine of the patient; CAD (computer-aided design) data are imported into Geomagic, an instruction for removing noisy points in bones is performed, and a three-dimensional solid is obtained; a screw implanting route is simulated on the extracted spine model, a curved surface contacted with the spine is extracted according to the shape and the position of the spine and is sheared with a rectangle, and an operation guide plate matched with a contact part in shape is obtained; positions of guide holes and positioning holes are determined; a three-dimensional CAD data model of a spine implant prosthesis is imported into Magics 17.0 for treatment, a multi-layer slicing two -dimensional CAD data model file of the spine implant prosthesis is obtained and imported into 3D printing equipment, and the operation guide plate is obtained. According to the manufacturing method, the situation that a surgeon depends on traditional experience or expensive equipment such as a navigation system and the like is avoided, the surgeon does not depend on fluoroscopy during an operation and is not affected by posture changes, a learning curve is shortened, and marks are reduced.

The present invention relates to the use of a TLR9 agonist and/or a TLR4 antagonist and/or a NOD2 agonist for treatment or prevention of disorders involving TLR4 activation, such as systemic sepsis and necrotizing enterocolitis.

The invention relates to the technical field of hardware circuit design and manufacture, in particular to a processing technology of a golden finger. The processing technology comprises the following steps: copper selection, initial cleaning, polishing, chemical micro-etching, deep cleaning, drying, pattern plating and plating of the golden finger. In the step of the initial cleaning, the surface dedusting is firstly carried out on copper, and then a detergent is adopted for cleaning. In the polishing step, No.40 sand paper is adopted for polishing the copper, thereby breaking a stubborn dirt layer and an oxide layer on the surface of the copper and forming the matte surface on the surface of the copper. The matte surface is formed on the surface of the golden finger processed through the technology, thereby effectively reducing the production of imprints on the surface of the golden finger during the production test or the use, and greatly reducing the scrappage rate.

A thermoforming apparatus provided with: a casing material having a region for accommodating a substrate that is to be thermoformed, and a casing edge; and a heating plate, which has a heating surface that is square in planar view and a frame part that protrudes toward the casing material from the peripheral edge of the heating surface, and in which the frame part is capable of abutting against the casing edge of the casing material. The heating plate is provided with vacuum holes that open at the corner formed by the heating surface and the frame part at the periphery of the heating plate in planar view. Before adhesion, on the heating surface, of a sheet that is disposed between the casing edge of the casing material and the peripheral edge of the heating plate, there is a gap between at least a portion of the sheet and the heating surface.

The clamping jaw has the advantages of larger clamping force, larger gripping force, smaller impression marksand the wider application range.

An improved rotator/translator mechanism includes multiple thin discs that mate with an idler roll to distribute nip pressure and spin at different rotational velocities to produce the same linear velocity at the nip and thereby reduce marking on certain media.

The invention provides heat-clearing pain-relieving burn and scald ointment with an effect of relieving marks. The ointment is prepared from the following components in parts by weight: 20-25 parts of sea-buckthorn fruit kernels, 12-17 parts of cortex phellodendri, 10-15 parts of spina gleditsiae, 8-14 parts of sophora japonica stems, 8-14 parts of cortex meliae, 7-12 parts of uncaria rhynchophylla, 7-12 parts of caesalpinia sappan, 5-10 parts of camellia, 3-5 parts of fritillaria cirrhosa, 3-5 parts of castor beans, 3-5 parts of eucalyptus oil and 2-3 parts of bornoel. According to the ointment, traditional Chinese herbal medicinal materials are extracted by adopting different alcohol refluxing processes according to different properties of the traditional Chinese herbal medicinal materials instead of a traditional sesame oil extraction method, so that sufficient extraction of effective ingredients is guaranteed, and defects of more impurities and poor medicinal effect of the traditional Chinese medicinal ointment caused by over-high extraction temperature can be avoided. The ointment can be used for effectively clearing heat, removing toxicity, removing necrotic tissues, promoting tissue granulation, promoting wound healing and relieving marks.
