  • Publication number: 20060169980
    Abstract: An electrochromic display is disclosed which comprises an array-side substrate (10) wherein a TFT (14) and a pixel electrode (15) connected with the TFT (14) are formed, a color filter-side substrate (50) wherein a counter electrode (53) is formed, and an electrolyte layer (80) injected between the array-side substrate (10) and the color filter-side substrate (50). In this electrochromic display, the TFT (14) is formed to have an area not less than 30% of the area of the pixel, thereby supplying a larger current. Consequently, oxidation-reduction reaction in the electrochromic phenomenon proceeds at a higher rate, thereby enabling a high-speed response.

  • Publication number: 20050284229
    Abstract: A pressure sensor comprising a plurality of sensor parts arranged in matrix. A first electrode being connected with first wiring and a second electrode being connected with second wiring are disposed oppositely through a cavity part in the sensor part. The second electrode bends to the first electrode side in response to a pressure from a specimen and touches the first electrode upon application of a pressure of a specified level or above. When the specimen is pressed against a pressure detecting region, both electrodes touch each other at a sensor part corresponding to a protrusion of the specimen and are separated at a sensor part corresponding to a recess. When a scanning signal is fed from a scanning circuit to one wiring and presence of a signal flowing through the second wiring is detected by a sensing circuit, a pressure being applied to each sensor part can be detected.

  • Patent number: 6543770
    Abstract: The present invention aims to reverse and transport a card in an automated card game machine, and relates to a card reversing device that reverses and transports each card, with no one touching the card. The present invention also relates to such a card game machine and a card reversing method. Each card placed on a card placement unit of a table is pulled by the magnetic force of a magnetic circuit having three electromagnet units. Accordingly, when a slider that supports the magnetic circuit is moved by a card transportation mechanism, the card slides on the upper surface of the card placement unit as if to follow the movement of the magnetic circuit. With one end portion of the card being attracted to the center electromagnet unit, the card is reversed by 180 degrees by the repulsive force generated between the other end portion of the card and the left-side electromagnet unit.

  • Patent number: 5686836
    Abstract: An apparatus for measuring a weak magnetic field in a background D.C. magnetic field such as the earth's magnetic field or the like includes a magnetic pickup portion that is supported by a support mechanism which does not impede minute movement in the x- and y-axis direction. A pair of A.C. linear gradient magnetic fields whose directions of gradients are parallel to the x-axis and y-axis, respectively, are used for obtaining reference signals for sensing the position of the pickup portion. The frequencies of the A.C. linear gradient magnetic fields are set to be sufficiently higher than the frequency of the weak magnetic field that is to be measured. The A.C. linear gradient magnetic fields are provided by A.C. current flowing in two pairs of linear conductors which are perpendicular to each other.
