Abstract: An auger-suction type metro jet system (MJS) device for aerated and lightweight cement soil includes a multi-pipe device, an outer sleeve, an integrated device, a spiral conveyor, a reamer head, a pressure monitoring system, a mass measuring device, and a control console. The multi-pipe device integrates a backup pipe, a negative-pressure gas pipe, a hydraulic pipe, a negative-pressure water pipe, a pressure sensor wire pipe, a pressure water pipe, a backup gas pipe, a power wire pipe, and at least one grouting tremie unit. The spiral conveyor includes a shaft-type spiral conveying belt and a negative-pressure device. A construction method for foundation reinforcement construction includes: cutting soil by the reamer head; crushing gravel by a gravel crusher; transporting, by the shaft-type spiral conveying belt, a soil-water mixture to a waste liquid tank; monitoring, by the mass measuring device, a mass of the soil-water mixture discharged; and injecting equal-mass cement.

Abstract: Provided is a multilayer film that includes a top layer and a barrier layer. The top layer includes a polyurethane network and having an exposed major surface. The barrier layer includes a fluoropolymer and having opposed first and second major surfaces, where the first major surface is modified by a surface treatment and wherein the top layer is disposed on the first major surface. When bonding to a curable substrate, the barrier layer can prevent migration of low molecular weight species from the curable substrate into the polyurethane network, thereby avoiding discoloration resulting from exposure of these species to ultraviolet light and other weathering factors.

Abstract: In an aspect, a semiconductor includes a substrate. The substrate includes a column comprising a conductive paste that passes through a plurality of metal layers, a resin sheath surrounding the column, a ground shield surrounding the resin sheath, and a plurality of sense lines. The plurality of sense lines include a first sense line that is connected to the column comprising the conductive paste and a second sense line that is connected to the ground shield. The resin comprises a dielectric material.

Abstract: Disclosed is a positioning grouting anchor rod suitable for preventing and controlling an engineering seepage damage and a construction method thereof. The positioning anchor rod comprises an anchor rod, a grouting guide pipe and a grouting pipe. When the seepage failure occurs in the project, a water pump can be connected with a drain pipe interface to realize water drainage, and at the same time, a positioner can be used for positioning grouting in the seepage failure area to improve the accuracy of grouting reinforcement. A drainage channel and a grouting channel involved in the present application are independent of each other and do not interfere with each other, and the drainage and grouting functions are combined on the basis of retaining the original supporting function of the anchor rod.

Abstract: Provided is a drainage grouting pipe and a method of use thereof. The drainage grouting pipe comprises a perforated steel pipe, a plurality of elastic anti-filtration geotextiles, a movable stopper, and a grouting pipe. The perforated steel pipe consists of a front conical tip, a middle grouting section, a rear hole-free section, and a steel pipe seal. The middle grouting section is provided with a plurality of grouting holes. The surface of the middle grouting section of the perforated steel pipe is seamlessly, and circumferentially wrapped by the plurality of elastic anti-filtration geotextiles, and gaps are formed between adjacent elastic anti-filtration geotextiles. Firstly, the geotechnical layer is drained by a pumping system, and then the grouting position in the geotechnical layer is located and controlled by pulling out the grouting pipe to control the plunging depth of the movable stopper, thus achieving the prevention and treatment of groundwater seepage damage.

Abstract: A device that includes an integrated device, a plurality of solder interconnects, and an integrated passive device (IPD). The integrated device includes a die having a front side and back side, and a metallization portion coupled to the front side of the die. The metallization portion includes at least one metallization layer and a plurality of under bump metallization (UBM) interconnects. The plurality of solder interconnects is coupled to the metallization portion. The integrated passive device (IPD) is coupled to the metallization portion of the integrated device such that the IPD is located between at least two solder interconnects from the plurality of solder interconnects.

Abstract: Method for and apparatus were fans and cable placed at the ends at the same end of a computer rack drawer. The cable ends are located between the fans and the computing elements. The bulk length of each cable passes through the region where the fans are located. Air, and optionally EMI, sealing are provided by an elastic material near the fans. In this way cables could exit the same tailstock of the drawer where fans are located. The cable ends can receive good cooling, and the distance between the cable ends and computing elements of the drawer is not lengthened by the fan position.
