  • Publication number: 20090280874
    Abstract: It is an object of the present invention to provide an opening/closing hinge device which can be produced simple in construction and inexpensive in production by reducing the number of the parts forming part of the mobile device and to provide a mobile device small in size, reduced in cost and sufficiently reliable in the hinged members. The second member is rotated with respect to the first member toward the opening operation direction through the movable cam (150) by the urging force of the urging means (170) when the operation cam (130) is displaced in the predetermined operation direction by the external operation force. The fixed guide member (110) has inclined guide portions (115) each inclined at an advance angle in a predetermined inclination direction with respect to the surface perpendicular to the guide center axis to have the second rotation cam (140) rotated around the guide center axis in response to the displacement of the second rotation cam (140) along the guide center axis.

  • Patent number: 7327729
    Abstract: The communication system supports reservation of network resources. The base stations relay packets among the terminals, and perform priority control based on the priority set to the packets. In the terminal, the communication-managing table stores communication information of own terminal and a partner thereof. The packet-transmitting unit, setting priority to the packets, transmits the packets. When link condition of own terminal change, the link-managing unit updates, in order to prevent from quality deterioration of the other terminals, the priority of each of the packets whose source terminal is the own terminal.

  • Patent number: 7154768
    Abstract: A device and method of reading a ferroelectric memory, including providing a ferroelectric memory including a ferroelectric memory cell, a charge integrator, and a bit line connecting the ferroelectric memory cell and the charge integrator. Pulses are applied to the ferroelectric memory cell, where each of the pulses are of a value lower than that which will destroy data stored in the memory cell. Output voltage values from the ferroelectric memory cell are accumulated by the charge integrator in response to each pulse. The output of the charge integrator may be read to determine whether the datum value stored in the memory cell is a logic high or low value. In one embodiment, the output of the charge integrator is read at a predetermined time after starting the pulses.
