Title: Three axes system magnetic detector
Inventor: TSURUGA KIKUO
IPC: G01R33/02
Filed: 1983-04-26
Abstract: PURPOSE:To constitute a titled detector so that the external magnetic field has a wide and high accuracy linear characteristic, extending from the vicinity of zero to a magnetic field of a bridge balance point of a detecting circuit, by incorpoating a correcting circuit by which an output to the external magnetic field has the linear characteristic, in the poststage side of the detecting circuit. CONSTITUTION:A coil having a high permeability magnetic material as a magnetic core is connected in series to a position relation in which an X axis, a Y axis and a Z axis are orthogonal to each other. In this case, the coils whose inductance and variation of the inductance to the external magnetic field become the same, respectively, are used. Subsequently, when the external magnetic field is applied from some direction to a magnetic sensor having such a constitution, a variation of the total inductance LT in case each coil is connected in series is proportional to a square of the external magnetic field Hex. That which has fetched a variation of this total inductance LT as a detecting output of a Wheatstone bridge circuit is corrected by inputting the detecting output to a correcting circuit 5, so that an output of its correcting circuit becomes linear to the external magnetic field.

Abstract: PURPOSE:To decrease the number of necessary terminals and to shorten manufacturing process and also, to prevent the contact of mutual terminals, by providing resistance to a pair of arms set on the substrate and forming a catalyst layer on one hard resistance and then, activating the catalyst layer by heating with applying voltage. CONSTITUTION:Resistances 2a, 2b are provided on arm parts 1a, 1b of a ceramic substrate 1 having a pair of the parts 1a, 1b and a ceramic coating layer 7 is formed on the resistances 1a, 1b. A dense layer 7a is so made as to form on the lower layer  of the layer 7 and a coarse layer 7b is so made as to form on the upper layer of the layer 7. An oxidation catalyst layer of gaseous CO 4 is then formed only on the layer 7 of the resistance 2a. An application of voltage for the resistance 2a, 2b and derivation of output are performed by terminals 3a, 3b and 3c. Thus, a terminal for heating the catalyst layer 4 is unncessary to provide independently by providing the layer 4 on one face of the part 1b with the resistance 2a. In this way production is rationalized and also, a short-circuit is prevented because a space between each terminal 3a-3c is left sufficiently.
