摘要： A stable sensor designed to detect accurately the total NOx concentration under 100 ppm in terms of the NO gas concentration is made up of a first cell and a second cell with a gas diffusion aperture provided between the two cells. The first cell has a partition wall of a substrate of oxygen ion conductor containing zirconia as the main component and permitting a gas to be detected to enter the zirconia substrate; oxygen pumping electrodes are also formed on the first cell substrate which functions to expel oxygen in an atmosphere of the first cell to the outside and to reduce NO.sub.2 of the NOx gas to be detected to NO gas. While NO gas entering through a gas diffusion aperture between the two cells flows into the second cell, a measurement is made of an electromotive force between a NO detection electrode formed in the second cell and a counter electrode also formed therein or a counter electrode formed on the reverse side of the zirconia substrate, since such electromotive force corresponds to the level of the NO gas concentration and thus provides the total NOx concentration.

摘要： An object is to provide a lighting apparatus the cost of which is low, which is excellent in terms of heat dissipation capacity, and which does not make a human get burned even in the case where the human directly touches the lighting apparatus.An LED substrate unit (1) is mounted on a metal heat conduction plate (3) with high heat conductivity. Resin heat radiation plates (4, 5) with high thermal emittance and low heat conductivity are adhered to the entire exposure surface of both surfaces of the heat conduction plate (3) except for a portion on which the LED substrate unit (1) is mounted. Thus, a three layer structure is formed of the heat conduction plate and the heat radiation plates provided on both surfaces of the heat conduction plate. Heat discharged from the LED substrate unit (1) is diffused in the heat conduction plate (3) and transmitted to the resin heat radiation plates (4, 5), and the transmitted heat is discharged from the resin heat radiation plates (4, 5) to outer air.
