  • Publication number: 20090231516
    Abstract: A plurality of panels (40) are cut from a large substrate (mother substrate) including a lower large substrate (41A) and an upper large substrate (42A). For each panel (40), a frame-shaped seal (47) and a connection electrode forming section (C) are formed in the large substrate. Since the left side (47c) of the frame of a panel (40) is close to the right side (47b) of the frame of the left-adjacent panel, these sides of the seals are formed from a sealing material containing a lower density of spacers. Since the upper side (47a) of the frame of a panel (40) is separated from the lower side (47d) of the frame of the upper adjacent panel (40) by an extension (C?) for the connection electrodes, these seal members are formed from a sealing material containing a higher density of spacers.

  • Patent number: 7578162
    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 exerted 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.

  • Patent number: 7533582
    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.

  • Publication number: 20080289417
    Abstract: Static and dynamic acceleration as well as static and dynamic angular velocity are detected with a simple structure. An acceleration detecting section includes a weight body, a pedestal around the weight body, flexible plate-like bridge portions, and piezoresistive elements embedded in the upper surface of the bridge portions. An angular velocity detecting section includes a weight body, a pedestal around the weight body, flexible plate-like bridge portions, and piezoelectric elements fixed to the upper surface of the bridge portions. The pedestals are fixed to a device chassis. When the weight body is displaced by acceleration, the plate-like bridge portions are deflected, so that the acceleration is detected based on the change in the electrical resistances of the piezoresistive elements.

  • Publication number: 20080210008
    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.

  • Patent number: 7219561
    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).
