  • Patent number: 7933638
    Abstract: To provide a portable terminal which can detect the using modes of the portable terminal, can reduce the number of members necessary for detecting the using modes and further can reduce leakage magnetic force badly influencing on other devices. A portable terminal 10 includes a first casing 11 and a second casing 12 having inner side surfaces 11a, 12a capable of opposing to each other, respectively, and a hinge 13 for coupling the first casing 11 and the first casing 11. The first casing 11 is provided with magnetic materials 21, 22a, 22b and the casing 12 is provided with magnetic sensors 24, 25a, 25b for detecting the magnetic materials 21, 22a, 22b, respectively. The magnetic sensors 24, 25a, 25b and the magnetic materials 21, 22a, 22b detect the using modes including a folded state or a bent state of the first casing 11 and the casing 12.

  • Patent number: 7035606
    Abstract: A clock control apparatus (3) receives wireless frequency information of a wireless communication apparatus (6) from an information communication apparatus (5). Also, the clock control apparatus (3) detects an operation clock frequency of a main CPU (4). Then, when the multiplied operation clock frequency coincides with the wireless frequency, the clock control apparatus (3) lowers a voltage of the operation clock of the main CPU (4) to a minimum voltage value at which the operation of the main CPU (4) is guaranteed. Alternatively, the clock control apparatus (3) may shift the clock frequency, or may frequency-modulate the clock frequency.

  • Publication number: 20050270396
    Abstract: In a fold-up type of portable telephone device, the casing to be opened/closed has liquid crystal display devices on its front and back sides, which causes occurrence of noise. In view of this, in the liquid crystal display device of a portable telephone device, a flexible connection substrate is used to integrally form first and second liquid crystal display parts with a driver circuit shared therebetween. The first liquid crystal display part is connected to the flexible connection substrate to which the second liquid crystal display part is connected. The second liquid crystal display device is formed by adding the flexible connection substrate to the first liquid crystal display part, and both are driven by the driver circuit. Not only an alternative display but also simultaneous displays can be selectively performed.
