  • Patent number: 7464261
    Abstract: A switching device for controlling a connection between a private computer, a shared computer, and a terminal, including: a connecting unit that connects each terminal to a corresponding private computer in a default status, and switches a connection destination of the terminal to a private computer corresponding to the terminal or the shared computer when a connection switching request transmitted from the terminal has been received; and a security unit that executes for each terminal, identification processing on the data that has been received from any one terminal and output to the at least one private computer or the shared computer.

  • Patent number: 7136049
    Abstract: An input apparatus of the resistive type that is thinner and more durable is provided. The apparatus includes a first substrate having a conductive film on which a plurality of slits are formed in stripes, and a second substrate spaced apart from the first substrate at a fixed distance to face the surface of the first substrate implementing the conductive film. This second substrate has a conductive film formed on the surface facing the conductive film of the first substrate. A driving voltage is applied between two predetermined points on the conductive film formed on the first substrate. An electric potential of the conductive film formed on the second substrate is detected when the two conductive films come into contact.

  • Patent number: 7106308
    Abstract: Relating to input devices and electronic devices generating a signal corresponding to a position depressed on their input domain, an input device and an electronic device are capable of performing an easy correction. The input device generates the signal corresponding to the position depressed on its input domain, and contains a correction domain and a correction unit. The correction domains are set in several positions in a periphery of and different from the input domain. Based on the signal corresponding to the position depressed on the correction domain, the correction unit corrects the signal corresponding to the position depressed on the input domain.

  • Patent number: 6934792
    Abstract: A computer switch, for connecting an input device to a plurality of computers, which comprises a switching-command receiving unit for selecting from a plurality of computers a desired computer other than a computer which is currently actively connected with the input device and for receiving a switching command, which activates the connection between the desired computer and the input device, from the computer, which is currently actively connected with the input device, and a switching unit for activating connection from the input device to the computer corresponding to the switching command after the switching command is received.

  • Patent number: 6894682
    Abstract: Improves the connection between a touch panel and an external harness. A first electrode cable (11) and a third electrode cable (13) are disposed on a first ITO film (20) on a glass substrate (10) of a touch panel, and a second electrode cable (12) and a fourth electrode cable (14) are disposed on a second ITO film (60) on a flexible resin (50). First to fourth guide conductors (31 to 34) are disposed in parallel on a first insulation layer (30) that is provided near a first side (10a) of the glass substrate. The first to fourth electrode cables are connected to the first to fourth guide conductors, via first to fourth connection conductors (21 to 24). A second insulation layer (40) is laminated on them. On a connection section (6) of an external harness (4), first to fourth external conductors (81 to 84) have their coating removed at the touch panel side, and are superimposed with the plurality of guide conductors of the touch panel so that they cross each other.

  • Patent number: 4392421
    Abstract: A rice hulling and sorting machine includes a pair of hulling rolls which drop husked rice grains into a pneumatic sorting compartment which the husks are preliminary sorted from the rice grains; the rice grains thereafter being thrown upwardly into one end of the upper of two horizontally mounted rotating sorting cylinders. The interior surfaces of these cylinders have a multitude of recesses for trapping single rice grains at the bottom of their circumferential paths of movement to carry them upwardly and dropping them into conveying troughs which run the length of the interiors of the cylinders. Rice grains which are not trapped in the upper cylinder are fed back into the hulling rolls while those dropped into the upper trough are fed to the lower interior of the lower cylinder where they are again subject to being trapped in the recesses of the lower cylinder and dropped into the lower conveyor trough.
