    摘要: A gas sensor including a detection element having a front-end portion, a detection portion formed at the front-end portion of the detection element, and a protector that covers the detection portion. The protector includes a first portion having a first sidewall and a second portion having a second sidewall disposed outside the first portion. The first sidewall has an axial front end and a tapering portion. The tapering portion is formed from the axial front end of the first sidewall. The side portion has a front-end surface provided with a first gas outlet, and the second portion has a front-end surface provided with a second gas outlet. Furthermore, at least one gas inlet is formed to the sidewall of the second portion opposite the tapering portion, and plural gas inlets are formed on the sidewall of the first portion.

    摘要: A prismatic ceramic heater for heating a gas sensor element includes a heating resistor embedded in ceramic, and has a substantially rectangular cross section. At least part of a longitudinally extending edge portion of the prismatic ceramic heater is located in the vicinity of the heating resistor. This part of the longitudinally extending edge portion is coated with a porous protective layer. The protective layer has a thickness not less than 20 μm and a curved surface of a curvature radius not less than 10 μm. The protective layer prevents cracking induced by contact with water.

    摘要: Genetic recombinant yeast expressing xylose reductase (XR), (wild-type or mutant) xylitol dehydrogenase (XDH), and xylulokinase (XK) and a method for highly efficiently producing ethanol from xylose using the yeast are provided. Pichia stipitis-derived XR and (wild-type or modified-type) XDH genes and Saccharomyces cerevisiae-derived XK gene were introduced via chromosomal integration. Thus, a genetic recombinant yeast having a high xylose fermentation rate, being capable of producing ethanol from xylose in high yields, and having high xylose fermentability in the presence of glucose, as well as a method using the recombinant yeast for highly efficiently producing ethanol from xylose or a saccharified solution from lignocellulose-based biomass are provided. Furthermore, a method for improving the xylose fermentability of the genetic recombinant yeast of the present invention via acclimatization treatment is also provided herein.
