Some embodiments are methods which include preparing a slickline cable by providing an inner metallic tube containing at least one conductor (such as an optical fiber), disposing an epoxy/fiber composite strength layer substantially upon the outer periphery of the inner metallic tube, and exposing the combination of the inner metallic tube and composite strength layer to at least one technique for minimizing the variation in diameter and providing a substantially uniform circular cross-sectional shape of the combination. Further, an outer metallic tube is draw around the combination of the composite strength member and the inner metallic tube, to form a wellbore slickline. Cables prepared using such methods are also disclosed.

A processing method of a polishing pad for semiconductor wafer capable of forming a groove, a concave portion, a through hole and the like having a small surface roughness of the inner surface of the groove and the like of 20 mum or less, a high dimensional accuracy and a uniform cross-sectional shape, and a polishing pad for semiconductor wafer. In the processing method, a surface of a polishing pad including a water-insoluble matrix containing a crosslinked polymer and a water-soluble particle dispersed in the water-insoluble matrix is processed by cutting and the like. Additionally, when a groove and the like are formed, it is preferable that a polishing pad is placed on one surface side of a machining table having a sucking hole, the pad is fixed on the one surface side of the machining table by vacuuming sucking it from the other surface of the machining table, and then a groove and the like are formed.

A cord manager for a suspended electric lighting fixture holds the fixture's power cord in close parallel relation to the fixture's suspension cable at electrical feed locations. The cord manager, which is suitably fabricated of extruded plastic, has an elongated first body portion with a lengthwise cable retention channel and an elongated second body portion having a power cord retention channel. In one embodiment of the invention, the retention channel for the suspension cable opens onto the power cord retention channel. In another embodiment, the suspension cable and power cord retention channels open outwardly away from each other. The cord manager provides the clean, finished look to the lighting installation at power feed locations.

The invention is a staple comprising a bridge member having a top surface and an opposing bottom surface defining a thickness between and two lateral edges defining a width therebetween and either the thickness or the width includes a center flared area, such as a “diamond-like” shape meaning that it has a v-shape on opposing lateral edges flanked by opposing fillets to form an inserter mount area and the staple has a pair of legs spaced apart along the axis and each joined at a rounded flared shoulder to the bridge member. In a four-legged version the bridge has a waist.

A connector connection terminal that is less likely to buckle and in which cutting task is facilitated is provided. The present invention provides a connector connection terminal in which substantial height dimension from a rotation recess to an end face at an end on a rear surface side is set larger than a substantial height dimension from the rotation recess to an end face at an end on the front surface side, and an upper surface from the rotation recess to the end face at the end on the rear surface side is a flat surface.

The invention provides an extrusion head for pole piece forming, a forming device comprising the extrusion head, a forming method of the extrusion head and a preparation method of the extrusion head.The extrusion head comprises an extrusion head shell, and a through extrusion channel is formed in the extrusion head shell in the extrusion direction; the extrusion channel is divided into a transition cavity and a forming cavity which are sequentially communicated in a butt joint mode in the extrusion direction, and the diameter of the annular face of the inner wall of the transition cavity is gradually reduced in the extrusion direction. And the mixed pole piece mixture is extruded into a pole piece with a certain thickness by adopting a screw rod, and the pole piece is dried, and then directly passes through a specific cutting die, so the manufacturing of different types of special pole pieces is finished. And compared with other pole piece preparation methods, the preparation efficiency is obviously improved.
