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, at least two columnar force transmitting members (11, 12) are connected. Connecting members having flexibility are interposed at the upper and lower ends of each of columnar force transmitting members (11, 12) so that columnar force transmitting members (11, 12) can become inclined when force receiving member (10) becomes displaced upon receiving a force. Sensors (21, 22) are positioned at the respective connection parts of columnar force transmitting members (11, 12) and supporting member (20) to detect forces that are transmitted from the respective columnar force transmitting members (11, 12) to supporting member (20).

Abstract: The invention provides a force detector in which power consumption is suppressed. Four electrodes E11 through E14 are formed on a substrate, and an elastic deformable body formed of a rubber film is disposed thereon. A conductive coating is applied on the lower surface of the elastic deformable body to provide a displacing conductive layer 26. Four capacitance elements C11 through C14 are comprised by the electrodes E11 through E14 and the displacing conductive layer 26 opposed to the electrodes. The capacitance values thereof are converted into voltage values V11 through V14 by C/V converter circuit 50, and based on operation by signal processing circuit 60, an external force applied to the elastic deformable body is detected.

Abstract: 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 ?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. Thus, a Coriolis force Fy proportional to the angular velocity ?x is applied to the oscillator in the Y-axis. By this Coriolis force Fy, the oscillator is caused to undergo displacement in the Y-axis direction.

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, ?) by a polar-coordinate converting section 200. When a value r of the coordinate value (r, ?) obtained in time series is larger than a predetermined threshold rt, an operation-quantity recognizing section 300 recognizes the coordinate value (r, ?) as a significant coordinate value, and, when the value ? generates a variation ?? exceeding a predetermined threshold ?t with respect to a value “? before” immediately therebefore during a period during which a significant coordinate value (r, ?) is obtained continuously, it recognizes a value corresponding to the variation ?? as an operation quantity indicating a rotation.

Abstract: In a liquid crystal display device including a liquid crystal display panel (10) including a liquid crystal layer (3) sandwiched between a first substrate (1) and a second substrate (2) having transparent electrodes (5, 6) on inner surfaces opposing to each other, the film thickness of at least one of the transparent electrodes (5, 6) formed on the first and second substrates (1, 2) is set so that light passing through the transparent electrode and exhibiting a maximum transmittance has a color within either a region defined by an x value of 0.22 to 0.28 and a y value of 0.21 to 0.31 or a region defined by an x value of 0.28 to 0.34 and a y value of 0.22 to 0.35 in a chromaticity diagram of a CIE 1931 color system using a white light source. This reduces coloring irregularities due to a film thickness error caused during manufacturing of the transparent electrodes to enable performance of uniform display.

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.

Abstract: An acceleration sensor in a connecting portion connects a displacing section to a fixed section and a weight is connected to the displacing section from below. A pedestal is disposed adjacent to the weight and is connected to the fixed section by a pedestal joint layer so a displacement of the displacing section can be detected. The weight has a peripheral portion of its upper surface opposite a control surface on a lower surface of the fixed section to come into contact therewith upon a given magnitude of acceleration of the weight. A weight joint layer made of the same material as that of the pedestal joint layer joins the weight and the displacing section.
