    摘要: A flexible substrate (110) having flexibility and a fixed substrate (120) disposed so as to oppose it are supported at their peripheral portions by a sensor casing (140). An oscillator (130) is fixed on the lower surface of the flexible substrate. Five lower electrode layers (F1 to F5: F1 and F2 are disposed at front and back of F5) are formed on the upper surface of the flexible substrate. Five upper electrode layers (E1 to E5) are formed on the lower surface of the fixed substrate so as to oppose the lower electrodes. In the case of detecting an angular velocity .omega.x about the X-axis, an a.c. voltage is applied across a predetermined pair of opposite electrode layers (E5, F5) to allow the oscillator to undergo oscillation Uz in the Z-axis direction. By change of the capacitance value, it is possible to detect the magnitude of the Coriolis force Fy, and to determine angular velocity .omega.x. Similarly, it is possible to detect an angular velocity .omega.y about the Y-axis and an angular velocity .omega.z about the Z-axis.

    摘要: The periphery of a disk having flexibility is fixed to a sensor casing, and a force applied to the central portion is detected. A doughnut disk-shaped piezoelectric element is positioned on the upper surface of the disk, and upper electrode layers indicated by patterns of D1 to D6 are formed on the upper surface of the piezoelectric element. Further, lower electrode layers similarly having pattern of D1 to D6 are formed on the lower surface of the piezoelectric element, and the lower surface of the lower electrode layer is fixed on the upper surface of the disk. Six detection elements D1 to D6 are formed each of which is constituted by a pair of upper and lower electrode layers and a portion of piezoelectric element put therebetween. Thus, force components exerted at an origin defined in the central portion of the disk in respective axes directions of X, Y, Z can be detected based on charges produced in detection elements D1, D2, detection elements D3, D4, and detection elements D5, D6, respectively.

    摘要: A sensor comprises a semiconductor pellet (10) including a working portion (11) adapted to undergo action of a force, a fixed portion (13) fixed on the sensor body, and a flexible portion (13) having flexibility formed therebetween, a working body (20) for transmitting an exterted force to the working portion, and detector means (60-63) for transforming a mechanical deformation produced in the semiconductor pellet to an electric signal to thereby detect a force exerted on the working body as an electric signal. A signal processing circuit is applied to the sensor. This circuit uses analog multipliers (101-109) and analog adders/subtracters (111-113), and has a function to cancel interference produced in different directions. Within the sensor, two portions (E3, E4-E8) located at positions opposite to each other and producing a displacement therebetween by action of a force are determined. By exerting a coulomb force between both the portions, the test of the sensor is carried out. Further, a pedestal (21, 22) is provided around the working body (20). The working body and the pedestal are located with a predetermined gap or spacing therebetween. A displacement of the working body is caused to limitatively fall within a predetermined range corresponding to the spacing. The working body and the pedestal are provided by cutting a same common substrate (350, 350').

    摘要: An electrode layer is formed on the upper surface of a first substrate, and a processing for partially removing the substrate is carried out in order to allow the substrate to have flexibility. To the lower surface of the first substrate, a second substrate is connected. Then, by cutting the second substrate, a working body and a pedestal are formed. On the other hand, a groove is formed on a third substrate. An electrode layer is formed on the bottom surface of the groove. The third substrate is connected to the first substrate so that both the electrodes face to each other with a predetermined spacing therebetween. Finally, the first, second and third substrates are cut off every respective unit regions to form independent sensors, respectively. When an acceleration is exerted on the working body, the first substrate bends. As a result, the distance between both the electrodes changes. Thus, an acceleration exerted is detected by changes in an electrostatic capacitance between both the electrodes.

    摘要: A fixed substrate (10) having rigidity and a flexible substrate (20) having flexibility are arranged in such a manner that they are opposite to each other. Both the substrates are fixed at their peripheral portions by a detector casing (40). A working body (30) is connected onto the lower surface of the flexible substrate. Test electrodes (11t, 13t, 15t) are formed on the lower surface of the fixed substrate, and fixed electrodes (11, 13, 15) are further formed through an insulating layer (16). Displacement electrodes (21, 23, 25) are formed on the upper surface of the flexible substrate. When an acceleration is exerted on the working body, the flexible substrate is bent, so the distance between the fixed electrode and the displacement electrode is varied. By detecting the change of distance as a change of the electrostatic capacitance between both the electrodes, it is possible to detect an acceleration exerted. In order to carry out the operation test of this detector, a voltage is applied across the test electrode and the displacement electrode, thus allowing coulomb force to be exerted between both the electrodes. Thus, the flexible substrate is bent by coulomb force, resulting in the same state as the state where an acceleration is exerted. By examining a change of the electrostatic capacitance between the fixed electrode and the displacement electrode, the operation test can be conducted.

    摘要: A force detector is comprised of resistance elements having a piezo resistance effect such that electric resistance varies due to mechanical deformation, and formed on a single crystal substrate (10), and a strain generative body (20) having a supporting portion (21) and a working portion (23), thus allowing the resistance elements to produce a mechanical deformation on the basis of a displacement with respect to the supporting portion of the working portion. This force detector can detect a force applied to the working portion as changes in resistance values of the resistance elements. The plane on which resistance elements are to be formed on the single crystal substrate is selected so that piezo resistance coefficients in two directions perpendicular to each other exhibit peak. When a weight body (30) is connected to the working portion, it is possible to detect an acceleration acting on the weight body. Moreover, when a magnetic body (330) is connected to the working portion, it is possible to detect a nagnetic force acting on the magnetic body. By using the detector system for acceleration in common to the detector system for magnetic force to perform a compensation computation, detection of a magnetic force which is not influences by acceleration can be made. By devising an arerangement of resistance elements in either detector, it is possible to independently determine magnitudes of objects to be measured with respect to directions of the three-dimensional coordinate system, respectively.

    摘要: Force and moment exerted on the working point (P) on a semiconductor substrate (110, 210), on one surface of which resistance elements (r, R) having an electric resistance varying due to mechanical deformation are formed, are detected. A portion spaced from the working point of the semiconductor substrate is fixed. Since openings (113) or bridge portions (212 to 215) are formed in the semiconductor substrate, when a force or an angular moment in a fixed direction is applied to the working point, uneven stresses are produced on the semiconductor substrate. Such uneven stesses are detected as changes in electric resistances of the resistance elements. A measure is taken for an arrangement of resistance elements on the semiconductor substrate, thereby to constitute predetermined bridges. Thus, forces in three directions and angular moments in three directions in the three-dimensional space can be independently read as bridge voltages, respectively.
