摘要： A gas sensor of constant-current type is used to detect a gas component in exhaust gases from an internal combustion engine so as to perform feedback control of air/fuel ratio of an air-fuel mixture supplied to the engine. In order to detect an air/fuel ratio which is richer than a stoichiometric value, a voltage applied to the gas sensor is set to a high value so that the gas sensor does not exhibit a constant-current characteristic. In the case it is desired to detect an air/fuel ratio which is either richer or leaner than the stoichiometric value, the voltage may be changed between the high value and a lower value at which the gas sensor exhibits a constant-current characteristic. Engine parameters are detected to determine whether the engine requires a rich mixture or a lean mixture, and the voltage may be changed as the result of such determination. An output current of the gas sensor is detected to ascertain air/fuel ratio so that air/fuel ratio is controlled to a desired value suitable for engine operating condition.

摘要： An infrared rays excited - infrared rays emitting fluorescent material which contains predetermined quantities of neodymium and ytterbium as activators is disclosed.The fluorescent material according to this invention is higher in the luminescence intensity than a conventional, infrared rays excited - infrared rays emitting fluorescent material which is activated with neodymium only. Moreover, its maximum luminescence wavelength lies within a wavelength region which a silicon photosensor can detect at high sensitivity. It is therefore very useful in practical use.The fluorescent material is represented by the following formula:MM'.sub.1-x-y Nd.sub.x Yb.sub.y P.sub.4 O.sub.12wherein M denotes at least one element selected from the group consisting of Li, Na, K, Rb and Cs, and M' denotes at least one element selected from the group consisting of Sc, Y, La, Ce, Gd, Lu, Ga and In, and where 0.05 .ltoreq. x .ltoreq. 0.999, 0.001 .ltoreq. y .ltoreq. 0.950, and x + y .ltoreq. 1.0.BACKGROUND OF THE INVENTION1. Field of the InventionThis invention relates to a fluorescent material which is excited by infrared rays and which emits infrared rays (such a fluorescent material shall be termed an "infrared - infrared fluorescent material" in the present specification). More particularly, it relates to an infrared - infrared fluorescent material which is higher in the luminescence intensity than conventional infrared - infrared fluorescent materials and the peak of luminescence wavelength of which is well adapted to the responsivity spectrum of a solid-state photosensor.2. Description of the Prior ArtThe infrared - infrared fluorescent material had scanty applications in the past unlike other fluorescent materials, and only a very small number of substances were developed.Recently, however, the applications of the infrared - infrared fluorescent material have gradually widened for, e.g., the sensors of various analyzers. In consequence, an infrared - infrared fluorescent material exhibiting more excellent characteristics than in the prior art has been desired.It is stated in the following reference that several substances containing Nd, for example, CaWO.sub.4, Y.sub.3 Al.sub.5 O.sub.12, LaF.sub.3, CaNb.sub.2 O.sub.6 etc. can be used for solid-state devices for laser oscillation;(1) "Luminescence of Insulating Solid for Optical Masers," L. G. van Vitert in Luminescence of Inorganic Solids, ed. by Paul Goldberg, p. 465 - 5399, Academic Press 1966.Any of the above-mentioned substances has been used as the solid-state element for laser oscillation under the state of the single crystal, and there has not been any example in which it is employed as a fluorescent material. It is surely possible to use the substances as infrared - infrared fluorescent materials in the form of fine powder. The compounds which contain Nd ions have the properties that radiation in the infrared wavelength region is intensely absorbed by the Nd ions and that the efficiency of infrared emission is high. However, the concentration of cations to substitute is as low as several %, and the Nd ion concentration per unit volume is not high. Therefore, even if the substances are used as the powdery fluorescent materials, the influence of scattering on the powder surfaces will appear conspicuously, and it will be difficult to obtain a high output.Recently, several substances for new miniature elements have been reported in the following references:(2) "Minilasers of Neodymium Compounds," Stephen R. Chinn et al in Laser Focus, May 1976, p. 64 - 69.(3) "Stoichiometric Laser Materials," H. Danielmeyer in Festkorperproblem XV, p. 253, 1975, Viehweg (West Germany).The substance are the single-crystals of LiNdP.sub.4 O.sub.12, NdP.sub.5 O.sub.14, Al.sub.3 NdB.sub.4 O.sub.12 etc. A common feature is that the Nd ion concentration per unit volume is at least one order higher than the concentrations in the compounds mentioned previously. It is accordingly possible to obtain a high luminescence output even in case of the powdery form.However, the principal emission by the Nd ions lies in the vicinity of 1,050 nm, and this wavelength matches ill with the spectral sensitivity of a silicon photodetector which is the most excellent in the near infrared region. Accordingly, a fluorescent material with which a higher detector output is obtained is requested.SUMMARY OF THE INVENTIONAn object of this invention is to solve the problems of the prior arts and to provide a fluorescent material which has a high luminescence intensity and the luminescence of which can be detected at high sensitivity by a solid-state photosensor.In order to accomplish the object, this invention adds predetermined quantities of neodymium ions (Nd.sup.3+) and ytterbium ions (Yb.sup.3+) as activators, thereby to make the luminescence intensity high and to regulate the emission spectrum into a favorable shape.
