  • Publication number: 20130222043
    Abstract: In the device, a pair of transistors includes first and second transistors connected in parallel between a power-supply-line and a power-supply or between a ground-line and a ground-potential. A third transistor is connected between the power-supply-line and the power-supply or between the ground-line and the ground-potential. First to third nodes are gate nodes of the first to third transistors. A first buffer outputs a first control-signal for controlling the first transistor. A second buffer is connected between the first node and the second and third nodes to receive the first control-signal and transmit a second control-signal for controlling the second and third transistors to the second and third nodes in parallel. When power-supplying starts, the second control signal drives the second and third transistors to the conductive-state after the first control-signal controls the first transistor to be driven in an intermediate-state between the conductive-state and a shutoff-state.

  • Patent number: 8434331
    Abstract: Disclosed is a tubular knit glove and method of flatbed knitting. The outward portion of a thumb pouch (7) is knitted while the direction of the wales continues from the end of a four finger body (6) with a reciprocating motion in the direction of the course. Rows of stitches are knit in the center and yarn-overs (8,9) are added on each side as connecting stitches. The inward portion of a thumb pouch (10) forms rows of stitches that link with the yarn-overs (8,9) when knitting back from the end of the outward portion of the thumb pouch (7). After forming a thumb pouch (11), a five finger body (14) is knit as a circularly-knit tube wherein the knitting thread revolves in the course direction completing a glove (1).

  • Publication number: 20120289200
    Abstract: A contact sensor capable of inputting a character by tracing a character with user's finger is arranged in a region of a ten-key unit of a mobile telephone. When registering a password to release a key lock, a user traces a shape of a line, a character, a number, or other symbol on the contact sensor with his/her finger so that the shape is inputted and stored in a memory, thereby completing registration of a password. When releasing the key lock, the user traces the registered shape on the contact sensor with his/her finger so that the key lock is released. The input is easy. Even if the password input operation is observed by a third person, the password will not be easily known to the third person.
