A superheterodyne receiver employs as a local oscillator a VCO (125) included in a PLL (115). Upon depression of a station selecting switch (200), a pulse is generated and counted by a trinary counter (311) and two decimal counters (313, 315). The count value in the trinary counter is determined to indicate the channel index. The count value in the two decimal counters is subjected to the first addition (320) of "2" and the sum thereof is indicated as channel number data, while the same is subjected to multiplication (321) by 3 and the product thereof is subjected to the second addition (323) of a numerical value corresponding to the lowest channel frequency, whereupon the sum thereof is added in the third addition (327) to the count value in the trinary counter and the sum thereof is set in the PLL, while the same is indicated as the receiving frequency.

A display device includes a plurality of light emitting elements arranged in a matrix. A scan signal is made to flow into a gate signal line and a data signal is made to flow into a source signal line so that the data signal is applied to a source electrode and the scan signal is supplied to a gate electrode of a control TFT arranged at a portion where the both signal lines intersect when viewed from above. Thus, when the control TFT is turned ON, a drive TFT having a gate electrode connected to the drain electrode is turned ON, so that current is supplied from a power supply line via the source electrode and the drain electrode of the drive TFT to an organic EL element and the organic EL element emits light. A holding capacity is present between the control TFT and the drive TFT. Even when the scan signal becomes LOW level and the control TFT turns OFF, the gate potential of the drive TFT is held for a predetermined period of time by the holding capacity and the organic EL element continues to emit light.

To provide an electronic device whose manufacturing cost and weight can be reduced and whose sound quality can be prevented from deteriorating. Speakers 28 are provided on a rear side of a liquid crystal display part 20, inside a casing 12 so as to partly protrude downward from the liquid crystal display part 20, and sound guide ducts 24 linearly extend from a front face side of the speakers 28, and thus the sound guide ducts 24 are not bent. Therefore, even high-frequency sound generated from the speakers 28 can be outputted to an external part of the casing 12 without any sound quality deterioration. Further, the speakers 28 do not have to be disposed on a front face of the casing 12 which is on an outer side of the liquid crystal display part 20, and therefore, an electronic device 10 can be made compact, which can reduce weight and manufacturing cost of the electronic device 10.

A hinge device having a first installation frame (10) installed on a first housing (2); a second installation frame (20) installed on a second housing (3); a third installation frame (30) for rotatably supporting a base end section of each of the frames, the base end sections being supported such that a head section side of each frame is rotatable in a direction to approach to and separate from each other, the base end sections being supported through a first main shaft (40) and a second main shaft (50) that are arranged parallel to each other and to which rotation of the frames is transmitted; a rotation force transmission mechanism (80) disposed between the main shafts (40, 50) and including gears (81, 82) having a function of transmitting reverse rotation force from one to the other and vice versa; and a rotation angle restriction means (60). The hinge device enables stable closing operation in which displacement between the housings does not occur.

Provided is a wireless IP telephone set that, even when packet loss frequently occurs during a telephone call, keeps deterioration in audio quality to a minimum, permitting the telephone call to be continued without being interrupted. The wireless IP telephone set has a plurality of codecs. In a case where audio packet loss exceeds a predetermined value during a telephone call, switching to a lower bitrate codec is performed in different stages. In a case where there is no lower bitrate codec, a transfer request to a previously set transfer destination is transmitted.
