摘要： PROBLEM TO BE SOLVED: To provide a revolution number sensor stabilizing an output signal by providing an insulation layer between a magnet and an Si substrate. SOLUTION: When an ambient temperature becomes approximately 80 deg.C or higher, an Si substrate 22 is at an intrinsic conductive area and a resistance of the Si substrate is reduced. However, since an insulation layer 27 is provided between a magnet 26 and the Si substrate 22, the insulation layer 21 becomes a barrier even if the ambient temperature becomes approximately 80 deg.C or more and a resistance of a pair of Si substrates 22 is reduced. Thereby, since a current flowing in a pair of magnetic resistant elements 21 does not flow to the magnet 26 through the Si substrates 22, a middle point potential of a pair of magnetic resistant elements 21 is not varied. Thus, a revolution number sensor stabilizing an output signal can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a rotation speed sensor capable of stabilizing an output signal by preventing current flowing through a magnetoresistive element from flowing to a magnet via an Si substrate even when the resistance of the Si substrate drops at high temperatures.
SOLUTION: The rotation speed sensor has an insulating layer 27 formed of tape made of polyimide resin disposed between the magnet 26 and the Si substrate 22 having the magnetoresistive element 21. The insulating layer 27 formed of the tape made of polyimide resin prevents the current flowing through the magnetoresistive element 21 from flowing to the magnet 26 via the inside of the Si substrate 22.

摘要： PROBLEM TO BE SOLVED: To lessen the influence on output characteristics by comprising a shaft, which engages with the bearing of a mounting base, and a rotor with an incline to abut on a cantilever, at its periphery. SOLUTION: When a rotor 23 is rotated, an incline 25 rotates. A cantilever 20 abutted against the incline 25 is displaced, according to the quantity of rotation of a shaft 24, and the resistance value of a distortion detecting element 21 provided at the cantilever 20 changes. A terminal 16 electrically connected to the circuit pattern 22 of a substrate 17 outputs this change of resistance value, with the inclination of the incline 25 of the rotor 23 being the quantity of rotation of the shaft 24 as an output signal. Then, the quantity of rotation of the shaft 24 is regulated by making the rotation regulation part 26 provided at the rotor 23 and the projection 15 provided at the mounting base 11 abut on each other. Hereby, even if it is used for a long time, the influence on output property is lessened without producing abrasion powder by rocking.

摘要： PROBLEM TO BE SOLVED: To attain the use of a load sensor despite the small height of an operation part by preparing two distortion detection elements orthogonal to each other on a substrate and adding the plate type operation part above the axis of the upper surface of the substrate in parallel to the substrate. SOLUTION: A recess part 22b is formed around a projection 22a and approximately at the center of an attachment base 21, and the distortion detection elements 24 and 25 consisting of distortion gauges, etc., are placed orthogonal to each other on the upper surface of a substrate 23. A through-hole 26 is formed at the center of the substrate 23, and a terminal part 27 formed at an end part of the substrate 23 is electrically connected to both elements 24 and 25. Then the base 21 and the substrate 23 are fixed together via the fixing screws 28, and a screw 29 is placed on the projection 22a provided between the stage 21 and the substrate 23 so as to be inserted through the hole 26 and protruded over the substrate 23. A columnar shaft 30 which is inserted by the screw 29 on its lower face and also has an axis recess part 31 on its upper face is placed vertical to the substrate 23. Then a plate type operation part 32 is inserted to the part 31 of the shaft 30 and the upper surface of the part 32 is set in parallel to the substrate 23.

摘要： PROBLEM TO BE SOLVED: To make it possible to output a three-dimensional coordinate signal by providing a mounting base having a cantilever and a first strain detector between-the free end and fixed end of the beam, and a sub-shaft or an operating unit in contact with the free end of the beam. SOLUTION: A first strain detector 23 is formed by printing between the free end 24 and the fixed end 25 of a cantilever beam 22 of a mounting base 21 having the beam 22, a main shaft 26 having a through hole 28 therein formed by printing second strain detectors 29, 30 and third strain detectors 31, 32 on the upper surface is press fitted fixedly into the surface. A sub-shaft 35 is inserted into the hole 28, and assembled fixedly so that the through hole 34 of an operating unit 33 is engaged with the shaft 35. The shaft 35 is projected to the upper surface of the unit 33. The shaft 26 is deformed by the force applied to the unit 33, the resistances of the detectors 29, 30, 31, 32 are changed, and the load is detected as X-axis, Y-axis signals. When the shaft 35 is pressed, the end 24 of the beam 22 is pressed, and the load is detected as the signal of the Z-axis signal due to the resistance change of the detector 23 to input the three-dimensional signal.
