To shorten a carrier lifetime in an epitaxial layer.A technical idea of the present disclosure is that a carrier lifetime distribution including, as an element, a carrier lifetime in an epitaxial layer measured at a plurality of measurement points has the following features. (1) In a case in which the average value of the carrier lifetime is defined as τ_m, τ_m ≤ 0.4 µs is satisfied. (2) In a case in which the standard deviation of the carrier lifetime distribution is defined as σ_τ, σ_τ ≤ 0.5 τ_m is satisfied.

A folding transport container (10) comprising a base wall (11), a pair of opposed end walls (12) each pivotally attached to the base wall and a pair of opposed side walls (13) each pivotally attached to the base wall and perpendicular to the pair of end walls, at least one abutment surface (14) on each end wall and at least one second abutment surface (15) on each side wall to abut when assembled and at least one locking connection between each end wall and the pair of side walls, and at least one biasing component (20) provided between the base wall and at least one of the end walls or the side walls to bias the end wall or side wall away from the base wall in the assembled condition and depressible to move the locking surface and second locking surface out of abutment.

A method of laying one or more elongate flexible members through a pipe comprising the steps of attaching a first end of the or each elongate flexible member to a second end of a draw wire, pushing a first length of the or each elongate flexible member into the pipe in a direction from an entry end towards an exit end at a first rate, pulling a second length of the draw wire through the pipe from the entry end towards the exit end at a second rate and coordinating the first length and first rate with the second length and second rate to drive the or each elongate flexible member through the pipe.

An apparatus according to certain embodiments generally includes an elongated tubular member having a proximal end and an opposite distal end, and an inflatable balloon surrounding the distal end. The elongated tubular member comprises an outer tube, a non-collapsible inner tube positioned within the outer tube, and a compressible material positioned between the outer tube and the inner tube.

In an SiC single crystal substrate including a first main surface and a second main surface opposite to the first main surface, the SiC single crystal substrate in which the first main surface is a surface that tilts relative to a {0001} plane at an off-cut angle equal to or larger than 0° and equal to or smaller than 8° is used. In a distribution of phase differences obtained by measuring a phase difference between a first emission light and a second emission light emitted from the second main surface by making an incident light with two mutually perpendicular polarization components and a wavelength of 520 nm into the first main surface, an average value of the phase differences is equal to or smaller than 10 nm, and the maximum value of the phase differences is equal to or smaller than 70 nm.

The ostomy appliance (10) of the present disclosure comprises at least one appliance wall (11) of flexible sheet material forming a cavity (13) for containing a stomal output comprising stomal gas and stomal liquid and/or solids. The at least one appliance wall (11) comprises a stomal inlet (14) for receiving the stomal output and a gas vent (15) for allowing the stomal gas to migrate out of the cavity (13). A shield wall of flexible sheet material extends between the inner and outer walls across the stomal inlet. The shield wall comprises a spacer arrangement for at least partially separating the shield wall from the inner and/or outer wall for forming a fluid path therebetween. The spacer arrangement comprising at least one undulation of the flexible sheet material of the shield wall.

System and method for physical foaming injection suitable for manufacturing low-density member are provided. The method for physical foaming injection includes i) heating an inside of a barrel that is elongated in one direction; ii) providing resin beads in the barrel; iii) manufacturing a melt by rotating and heating the resin beads with a first screw provided in the barrel; iv) directly providing a gas for physical foaming in the barrel along a transferring direction of the resin beads by spacing the resin beads; v) providing a gas for physical foaming in the barrel and forming a supercritical fluid by agitating a second screw placed in front of a first screw, the first screw to be spaced apart the second screw along a transferring direction; vi) providing a mixture in which the supercritical fluid is incorporated into the melt while the melt passes through the supercritical fluid; vii) pressurizing a cavity formed by the combination of a upper mold part and a lower mold part by injecting gas into the cavity; viii) foaming the mixture in the cavity while injecting the mixture into the cavity; ix) reducing pressure of the cavity in multiple stages after the injection of the mixture, and x) separating the upper mold part and the lower mold part from each other to remove the foamed member with a low density of 0.1 g/cc to 0.5 g/cc.

A scintillator structure includes a scintillator and a reflecting material that covers the scintillator. Here, the scintillator includes a resin and a phosphor, and a phosphor particle perimeter indicating a normalized length of an interface between the phosphor and the resin in a cross-sectional image of the scintillator is smaller than 6.25.

A wound dressing (10) is selectively configurable for use in a pressure gradient wound therapy system and for use without a pressure gradient wound therapy system. The wound dressing (10) can include a covering layer (13), an aperture (12) and a microbial barrier (16). The microbial barrier (16) can be arranged to cover the aperture (12).
