摘要： PROBLEM TO BE SOLVED: To stabilize a resistance value by providing an electrode containing silver where burning temperature is set lower than that of a strain resistance element for the upper surface of both the end parts of the strain resistance element to that of an insulating board, and by providing an insulation layer on the upper surface of the strain resistance element. SOLUTION: An insulation glass layer 13 is provided on the upper surface of a metal base backing 12 for forming an insulating board 11, and a strain resistance element 14 is provided on the upper surface. A pair of electrode 15 where at least silver is contained and burning temperature is set at most to that of the strain resistance element 14 is provided from the upper surface of both the end parts of the strain resistance element 14 to that of the insulating board 11, and the electrodes 15 is connected to the strain resistance element 14. Paste-containing glass is printed onto the upper surface of the strain resistance element 14 for burning at approximately 600 deg.C for approximately 30 minutes, and an insulation layer 17 is formed. In this case, a cutout part is provided at the connection part of both the side edges of the strain resistance element 14, thus preventing the electrode 15 from flowing along the boundary part between both the side edges of the strain resistance element 14 and the insulating substrate 11, and the effective length of the strain resistance element 14, namely, a resistance value, is made uniform.

摘要： PROBLEM TO BE SOLVED: To provide a load sensor having output voltage unchanging even at ambient temperature changing time by setting thermal expansion coefficients of a metallic base material of a sensor substrate and an insulating glass layer in the almost same with each other. SOLUTION: Since a strain resistance element 21 is arranged on the upper surface of a sensor substrate, a resistance value of the strain resistance element 21 changes in proportion to a deformation quantity of the sensor substrate deformed according to the bending moment. This changing value is amplified as an output signal to an external device by an electronic circuit. At this time, when considering a case where an ambient temperature of a load sensor changes, since thermal expansion coefficients of a metallic base material 18 in the sensor substrate and an insulating glass layer 19 are set in the almost same with each other, even if an ambient temperature of the load sensor changes, tensile force and compressive stress are not respectively applied with a contact plane of the metallic base material 18 and the insulating glass layer 19 as a boundary, so that since bending stress is not applied to the strain resistance element 21 by a temperature change in a no-load state to a stick, the load sensor unchanging in output voltage can be provided.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of the useless consumption of the electric power by inputting the output of a disk-in signal outputting device into a mechanical control IC and reducing the driving torque of a stepper motor than at the time of not inserting a disk at the time of inserting the disk. SOLUTION: The output (f) of high level disk-in signal in the case of inserting the disk and the low level disk-in signal in the case of not inserting the disk are respectively inputted into the mechanical control IC 24 from the disk-in signal outputting device 23. And when the output (f) of the disk-in signal is high level, the output (h) and (i) of the mechanical control IC 24 are successively varied at the time of falling or rising of the output (g) of a timer circuit 21. Therefore, the interval between the output (h) and the output (i) of the mechanical control IC 24 becomes small and the rotational torque of the stepper motor 26 also becomes small. Also, when the output (f) of the disk-in signal is low level, since the mechanical control IC 24 is varied only at the time of falling of the output (g) of the timer circuit 21, the interval between the output (h) and the output (i) of the mechanical control IC 24 becomes large and the rotational torque of the stepper motor 26 becomes large.

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 improve linearity and hence output characteristics by providing a distortion detection element consisting of a thick-film resistor and a bias resistor on an elastic plate and connecting them by a circuit pattern and forming a thickness sensor. SOLUTION: A thickness sensor substrate 37 where a distortion resistor (distortion detection element) and a bias resistor 40 are printed on an upper surface in advance is fixed to a fixing member by a fixing part 32. Then, a roll 53 is arranged inside the U-shape of a movable member 43, the movable member 43 is arranged inside a fixed member 50 so that a contacting part 45 of the movable member 43 contacts the lower surface of the substrate 37 and finally a roll 55 is arranged at the lower part of the roll 53. When a printing paper 37 to be measured passes between the rolls 53 and 55, the roll 53 rises due to the paper thickness, the movable member 43 also rises and the substrate 37 is lifted by the contacting part 45 of the movable member 43, and a bending moment is applied to the substrate 37. Then, the resistance of a distortion resistor 39 that is proportional to the amount of deformation of the substrate 37 is outputted to an external device via a circuit pattern 41.
