  • Patent number: 12048956
    Abstract: A method of recovering fly ash, including a firing step in which raw fly ash powder containing unburned carbon is fired to remove the unburned carbon by burning; measuring the content of unburned carbon in the raw fly ash powder; and obtaining a fine fly ash powder which is a component under a sieve and has a decreased content of unburned carbon as a result of sieve-classifying the raw fly ash powder. The perforation size of the sieve used in the sieve-classifying step is set depending upon the content of unburned carbon in the raw fly ash powder. The sieve has a small perforation size when the content of unburned carbon is large, and the sieve has a large perforation size when the content of unburned carbon is small. The fine fly ash powder, which is the component under the sieve, is recovered through the firing step.

  • Patent number: 10367268
    Abstract: To provide a leaky-wave antenna that allows dual-polarization without limiting an emission range to either side. The antenna includes as an element unit (AE) a CRLH transmission line configured by multiply connecting CRLH unit cells (UC) in a periodic fashion between one ends and the other ends of two parallel lines (La, Lb). The respective unit cells (UC) have a left-handed series capacitor (C1, C2) on each of the two parallel lines (La, Lb) and have a left-handed parallel inductor (L1) between the two parallel lines (La, Lb). When power is fed between the two parallel lines (La, Lb), the two parallel lines (La, Lb) and the series capacitor (C1, C2) serve to emit a vertical polarization component, and the parallel inductor (L1) and a conductor between the two parallel lines (La, Lb) serve to emit a horizontal polarization component.
