  • Patent number: 11054382
    Abstract: A sensor includes a pump cell and a reference cell generating voltage Vs or current. The pump cell includes a pump cell first electrode and a pump cell second electrode. The surface of the pump cell first electrode includes a noble metal region formed of a noble metal, a ceramic region, and a coexistence region in which the noble metal and the ceramic material coexist. The width of the coexistence region in an A region of the surface of the pump cell first electrode is greater than the width of the coexistence region in a B region of the surface. The A region is a region close to the reference cell first electrode, and the B region is a region located further away from the reference cell first electrode as compared with the A region.

  • Publication number: 20200340940
    Abstract: A sensor element (10) including: a measurement chamber (150); a pump cell (110) including a solid electrolyte (111), an inner electrode (113) exposed to the measurement chamber, and an outer electrode (112), the pump cell being configured to adjust an oxygen concentration in the measurement chamber; a diffusion resistance portion (151); and a detection cell (120) configured to measure a concentration of a specific gas in the measurement target gas after the adjustment of the oxygen concentration. The outer electrode is covered by a porous layer (114) and is disposed in a hollow space (10G) surrounded by a gas non-permeable dense layer 115, 118. The hollow space is in communication with an air introduction hole (10h) that is open on a rear side relative to the diffusion resistance portion. The outer electrode is exposed via the porous layer to air introduced through the air introduction hole.

  • Publication number: 20070160729
    Abstract: Drying capsinoid-containing chili peppers for capsinoid extraction, such that hot drying is conducted so that, at a minimum, the weight of the capsinoid-containing chili peppers is reduced to not more than 20 percent, and the moisture content to not more than 10 percent, of that of the raw fruit, is useful for obtaining a stable product.

  • Patent number: 5532015
    Abstract: A process for quickly and reproducibly obtaining .alpha.-L-aspartyl-L-phenylalanine methyl ester with controlled water content is disclosed. Wet crystals of .alpha.-L-aspartyl-L-phenylalanine methyl ester obtained by crystallization are subjected to a drying step to adjust the water content to not more than 5 wt %, and subsequently a gas adjusted to a temperature of 20-80.degree. C. and relative humidity of 20-90 RH % is contacted with the dried crystals to control water content.
