Abstract: A technology for reducing the so-called “phosphor burn-in” phenomenon where the variation of luminance arises by reducing display luminance of a certain pixel caused by deterioration in a display apparatus constituted by an organic electro luminescence element is provided. In the display apparatus, when displaying an image acquired by an image acquiring unit, luminance substantially same as average luminance of the acquired image is set to a non-display area where the image is not displayed.

Abstract: A portable terminal device comprises an antenna for receiving radio waves from a base station, an incoming call alarm for notifying the user of the reception of radio waves, a control circuit provided between the antenna and the alarm for activating the alarm and a memory. The memory is capable of storing therein a predetermined incoming call rejecting condition or incoming call notifying condition via the control circuit. The control circuit includes comparison means for detecting whether one of information as to the current time and date, information as to the self-location of the device and information as to the caller or the combination of these items of information is in match with the incoming call rejecting condition or incoming call notifying condition stored in the memory. The control circuit has the function of changing over to predetermined incoming call rejecting means or incoming call notifying means when a match is obtained.

Abstract: In a radio reception apparatus compatible with adaptive modulation, based on a received IQ signal processed by a reception processing unit, a determining unit calculates EVM that corresponds to a magnitude of shift-off between a true symbol point and the received symbol point. The calculated EVM is averaged and thereafter applied to a control unit. The control unit compares the applied EVM with a prescribed threshold value, and determines with high accuracy, switching among a plurality of modulation methods having different multi-value numbers.

Abstract: A mobile communication terminal stores a plurality of response messages generated according to respectively different audio compression methods. If the mobile communication terminal is not answered when an incoming call is received, the mobile communication terminal transmits the one of the response messages that has been generated according to the audio compression method designated by a base station.

Abstract: A portable electronic device wherein a first case has a first sound radiating hole formed in the front wall thereof and positioned as opposed to a speaker and a second sound radiating hole formed in the rear wall thereof and positioned as opposed to the speaker. The two cases are rotatably joined by a hinge mechanism. The second case has a second knuckle constituting the hinge mechanism and is provided with a strip member for opening or closing the second sound radiating hole with the closing or opening movement of the second case. The strip member has a free end portion to be wound up by the second knuckle to open the second sound radiating hole when the two cases are in a closed state or to be paid out to close the second sound radiating hole when the two cases are in an opened state.

Abstract: An RF circuit (131–138) satisfies Pnoise+NF+G?Plim+sW (0?s?4) at an edge of a guard band with respect to a required transmission level PAll, an upper tolerance level of out-of-band noise Plim, a guard bandwidth W, and a noise level Pnoise, where NF is a noise figure and G is a gain. An IF circuit (121–123) satisfies PAll?Pin+G, where PIF is an output level of a BPF (123). Out-of-band noise levels are reduced to Pnoise by the steep BPF (123). The RF circuit (131–138) is structured so that noise from a local oscillator circuit (134) does not surpass noise from the IF circuit (121–123). Reductions in power consumption are thus realized in addition to guard bandwidth reductions, because of being able to eliminate out-of-band noise from an amplifier (138) using a low-loss filter (140) having an attenuation slope s.

Abstract: The invention provides a key input device comprising a plurality of key tops 7 arranged on a surface of a main body case, each of the key tops 7 having a body 73 of transparent resin, the key body 73 being provided with a light blocking film 71 formed over a front surface thereof, the light blocking film 71 being partly cut out to form a light transmitting pattern 72 representing a character. LEDs 8 are arranged below the key tops 7. Each of the key tops 7 has a semitransparent screen 9 formed on a rear surface thereof in an area to be illuminated with LEDs 8 and extending only over a region opposed to the light transmitting pattern 72.

Abstract: A communication apparatus of the present invention notifies a user that one of a plurality of events has occurred, and includes a first reception unit, a second reception unit, a detection unit, and a light emitting unit. The first reception unit receives from the user, for each time slot that composes a light emission pattern, designation of a light emission color or non-emission, as a light emission attribute of the time slot. The second reception unit receives a designation of an event to be corresponded with the light emission pattern. The detection unit detects that one of the plurality of events has occurred. The light emitting unit, when the detection unit detects that the event has occurred, emits light based on the light emission pattern designated in correspondence with the event.

Abstract: In a radio reception apparatus, a quadrature detector provides its digital output signal to a band-limiting filter after lowering a sampling frequency by a sampling frequency converter. Based on a correlation value obtained from an output of the band-limiting filter by a symbol timing detecting circuit, a symbol timing deviation detecting circuit detects a magnitude and a direction of a deviation of the timing of sampling in the sampling frequency converter, and controls timing of the sampling in the sampling frequency converter. Thereby, a symbol point of the correct timing is extracted.

Abstract: In a cellular phone, a first cabinet and a second cabinet are foldably connected by a hinge, and the two cabinets are electrically connected by a connection member arranged inside the hinge portion. The hinge portion is constituted by putting together a first fitting portion provided at a first inner case, and a second fitting portion provided at a second inner case. A cut-out for inserting the connection member is provided between the two fitting portions. The cut-out is covered by a first tongue piece that is attached to the first fitting portion, and a second tongue piece that is attached to a second outer cover.

Abstract: In a radio reception apparatus, a variable gain of a reception amplifier is adjusted by an AGC control unit for each frame of a received signal for execution of an AGC operation. The AGC control unit determines and indicates to a digital signal processing unit an AGC operation end point of time. The digital signal processing unit executes prescribed signal processing on a digital signal obtained after the end of the AGC operation, in a known signal segment. Therefore, reception errors caused by erroneous amplitude values of digital signals resulting from the AGC operation can be prevented.
