Abstract: 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.

Abstract: Forces and moments are detected in a distinguishing manner by a simple structure. A supporting member (20) is positioned below a force receiving member (10), which receives forces to be detected, and between these components, four columnar force transmitting members (11 to 14) are connected. Connecting members, having flexibility, are interposed at the upper and lower ends of each of the columnar force transmitting members (11 to 14) so that the columnar force transmitting members (11 to 14) can become inclined when the force receiving member (10) becomes displaced upon receiving a force. Sensors (21 to 24), each equipped with capacitance elements, are positioned at the connections parts of the respective columnar force transmitting members (11 to 14) and the supporting member (20) to detect forces that are transmitted from the respective columnar force transmitting members (11 to 14) to the supporting member (20). Based on the detection values of the sensors (21 to 24), a detection circuit (30) detects, in a distinguishing manner, forces and moments acting on the force receiving member (10). All of forces Fx, Fy, and Fz and moments Mx, My, and Mz can be detected.

Abstract: An efficient rotational-operation-quantity input device suitable to be built into a small electrical appliance is provided. An operational force applied by an operator is input in time series as a coordinate value (x, y) in an XY two-dimensional rectangular coordinate system by a two-dimensional force sensor 100, and is converted into a coordinate value (r, θ) by a polar-coordinate converting section 200. When a value r of the coordinate value (r, θ) obtained in time series is larger than a predetermined threshold rt, an operation-quantity recognizing section 300 recognizes the coordinate value (r, θ) as a significant coordinate value, and, when the value θ generates a variation Δθ exceeding a predetermined threshold θt with respect to a value “θ before” immediately therebefore during a period during which a significant coordinate value (r, θ) is obtained continuously, it recognizes a value corresponding to the variation Δθ as an operation quantity indicating a rotation.

Abstract: 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′).
