To improve the reliability of a silicon carbide epitaxial substrate. A silicon carbide epitaxial substrate including a silicon carbide substrate and an epitaxial layer formed on an upper surface of the silicon carbide substrate is used. Here, a plurality of surface defects is provided on an upper surface of the epitaxial layer. The plurality of surface defects includes minute surface defects that are defects satisfying L < d/tanθ where a length of the surface defect in plan view is denoted as L, a thickness of the epitaxial layer is denoted as d, and an off-angle of the silicon carbide substrate is denoted as θ. In this case, a density of the minute surface defects is 100 counts/cm² or less.

A razor cartridge having a housing with one or more primary blades mounted in a primary blade plane on a front surface and a channel within a rear surface, the channel extending inwardly from the rear surface toward the front surface, and a trimmer blade assembly comprising a trimmer blade attached to a trimmer blade support, the trimmer blade support comprising a trimmer blade guard, where the trimmer blade assembly is mounted on a first interior wall of the channel and a portion of the housing adjacent a second interior channel wall opposite the first interior channel wall comprises a trimmer blade cap. Also, a method of manufacturing the razor cartridge with the trimmer assembly attached to an interior channel wall.

An apparatus for separating particulate embedded into a planar substrate, the apparatus comprising a support mechanism for supporting the planar substrate, at least one application nozzle for directing a pressurised fluid or mixture at the planar substrate with embedded particulate, wherein the pressurised fluid is applied at a combination of pressure and distance relative to the planar substrate with embedded particulate to dislodge the embedded particulate without loss of material from the planar substrate.

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.
