A cutting insert, intended for drills, in particular long hole drills, includes a cutting edge from which a concavely curved, chip removing surface extends up to a ridge where the curved surface transforms into a top side of the cutting insert. A number of long narrow chip-embossing formations (e.g., grooves or beads) extend from the chip removing surface to the top side with the purpose of producing, in the underside of the chip, long narrow embossments in the form of either ridges or flutes in order to stiffen the chip and make it more prone to breakage.

The material formula thereof consists of the following materials: an ethylene-vinyl acetate copolymer, a propylene-ethylene copolymer, an interfacial compatilizer, a flame retardant, an antioxidant silane coupling agent and a lubricant, wherein, the Shore A hardness of the ethylene-vinyl acetate copolymer is less than 75, the weight content of the vinyl acetate in the raw material monomer is 30 percent to 70 percent, the Shore A hardness of the propylene-ethylene copolymeris less than 90, and the Shore A hardness of the interfacial compatilizer is less than 80. The invention can meet the high temperature resistant conditions of an aging test (135 DEG C 168h), and has the advantage of low cost.

The invention relates to a trimmed woven label and a preparation method thereof. The preparation method includes the preparation of overlock yarn, the design of the fabric structure, the weaving of the fabric, and the cutting of the fabric to obtain the trimmed woven label, wherein: the preparation of the overlock yarn: the overlock yarn is made of the inner core yarn and the outer yarn. Core-spun and twisted, the outer yarn is a low-melting point hot-melt filament, and the inner core yarn is a low-elasticity yarn; weaving: weaving the embryonic cloth according to the embryonic cloth structure, wherein the woven fabric is The technological parameters are as follows: the weaving temperature is between 110 and 160° C., and the pick is 300 to 700 times per minute. The edge-cut woven label prepared by the preparation method has better softness, is not easy to scatter edges, and is dimensionally stable.

The invention provides a fast recovery diode, which comprises an N type high-doping silicon substrate, a first N type doping semiconductor layer, a second N type doping semiconductor layer and a diode anode layer, wherein the first N type doping semiconductor layer is positioned between the second N type doping semiconductor layer and the N type high-doping silicon substrate, and the doping concentration of the first N type doping semiconductor layer is lower than the doping concentration of the second N type doping semiconductor layer. The fast recovery diode can provide the sufficient current carrier concentration during the reverse recovery, so the current fall softness can be maintained. The invention also provides a method for manufacturing the fast recovery diode.

The present invention relates to the field of disposable sanitary products, in particular to an ultra-thin diaper core body, which includes a body, and the body includes sequentially stacked wood pulp spunlace cloth, absorbent upper layer, fluffy non-woven fabric, absorbent lower layer, viscose spunlace Cloth, the absorbent upper layer includes two second SAP layers located in the middle, a first SAP layer located on the outside of the two second SAP layers, a first gap is provided between the two second SAP layers, and each first SAP layer There is a second gap between the adjacent second SAP layer, and the lower absorbent layer includes two third SAP layers in the middle, a fourth SAP layer outside the two third SAP layers, and two third SAP layers. A third gap is provided between the layers, and a fourth gap is provided between each third SAP layer and the adjacent fourth SAP layer, which solves the problem that the existing composite absorbent paper is physically compressed and has low softness and poor absorption speed. Not fast, the technical problem that polymer effective utilization rate is not high. It also proposes a method for making the core body of the ultra-thin paper diaper.

The invention relates to the technical fields of underwear and brassieres, and in particular to a bionic brassiere having natural sterilizing, health preserving and breast protecting functions and a making method of the bionic brassiere. The bionic brassiere comprises a cup part, wherein the cup part comprises a core and cups which are symmetrically connected to two sides of the core; each cup comprises a first latex layer, an upright cotton layer and a second latex layer which are sequentially arranged from outside to inside; a glue net layer is arranged between the upright cotton layer and the second latex layer; the glue net layer is arranged at the side close to the core; and a hand-pushed area is protruded on the side, away from the core, of the upright cotton layer. The brassiere provided by the invention, which adopts the natural latex layers, is natural and free from harm and good in antibacterial and anti-mite effect, so that an antibacterial performance of the brassiere is improved, and the brassiere is high in elasticity, high in softness, high in skin-friendly performance and strong in air permeability; with the adoption of the upright cotton layers, the air permeability of the brassiere is enhanced; with the adoption of the glue net layers, a supporting and shaping effect of the brassiere is improved, and the brassiere is deformation-resisting and good in durability; and with the application of the hand-pushed areas, a supporting and gathering effect of the brassiere is improved; therefore, the brassiere is high in practicability.
