The present invention relates to a foundation structure vertically installed on the ground, and comprising: an upper support layer 10 formed on the ground in the vertical direction; and a lower support layer 20 formed so as to extend downward from the upper support layer 10 and such that the width thereof is less than that of the upper support layer 10. The disclosed upper support layer 10 and the lower support layer 20 are structures formed from soil solidified by means of feeding and mixing an earth and soil-solidifying agent therein, and therefore are efficient and prevent overload due to boring equipment.

A light-emitting device (100) is provided with a metal part (2) atop a planar LED substrate (1), and an LED element (3) is disposed atop the metal part (2). A glass substrate (5) is provided to an upper surface of the LED element (3), and a wavelength conversion part (6) is formed on an upper surface of the glass substrate (5). The wavelength conversion part (6) comprises a light-transmissive ceramic layer formed by heating a mixture containing a phosphor, an organometallic compound, a layered silicate mineral, an inorganic particulate, an organic solvent, and water.

The invention discloses a shield tunneling machine shield tail synchronous embedded-type double-liquid grouting device comprising a first valve block, a second valve block and a shield body connecting block which are embedded in a shield tail. A liquid A passage, a liquid B passage, a piston passage and a water passage are arranged in each of the first valve block and the second valve block correspondingly, a piston rod is arranged in each piston passage, a piston is arranged in a piston cylinder, each piston rod is driven by a propelling cylinder, the liquid A passage and the liquid B passage positioned in the first valve block are communicated with the piston cylinder through a first communication passage, and the water passage positioned in the first valve block is communicated with the piston cylinder through a second communication passage. Position of the pistons is controlled by utilizing the propelling cylinders, so that overbreak clearance between a pipe piece and a tunnel stratum can be quickly made up after the shield tail is separated from the pipe piece in the process of shield tunneling, water seepage of joint and tail gap of the pipe piece is effectively prevented, and ground surface settlement is inhibited; the shield tunneling machine shield tail synchronous embedded-type double-liquid grouting device is suitable for various geographic conditions, simple to operate, less prone to being blocked and capable of improving construction efficiency.

A zirconium nitride powder which has a specific surface area of 20 to 90 m2 / g as measured by a BET method, has a peak corresponding to zirconium nitride but does not have a peak corresponding to zirconium dioxide, a peak for lower zirconium oxide or a peak corresponding to lower zirconium oxynitride in an X-ray diffraction profile, and the light transmittance X at 370 nm is at least 18%, the lighttransmittance Y at 550 nm is 12% or less and the ratio (X / Y) of the light transmittance X at 370 nm to the light transmittance Y at 550 nm is 2.5 or more in the transmission spectra of a dispersion that contains the powder at a concentration of 50 ppm.
