摘要： A portable radio apparatus having a casing thereof keeps a matching state of an antenna (20) thereof in the call waiting state and in the operating state of the apparatus. The casing is foldable and expandable and comprises an upper casing part (10) and a lower casing part (40). The upper casing part accommodates a transmitting and receiving circuit (11) connected via a variable matching circuit (12) to the antenna. The matching circuit is connected to a sensor (13a) disposed in the casing for sensing the folded state thereof. Depending on a result of the sensing operation of the sensor, the matching circuit changes the matching state by means of a switch (13).

摘要： A foldable portable telephone which allows the user to operate a power switch thereof and to see the ON/OFF state of the switch as well as a reception state even when put in the user's breast pocket in a folded position. A first and a second casing accomodating a transmitter and a receiver, respectively, are foldably connected together by a hinge mechanism. Indications or indicator indicative of the ON/OFF state of the power switch, an indicator for alerting the user to a call, and an opening for a sounder which produces an alert toner are positioned on or in close proximity to the ends of the casings which are remote from the hinge mechanism.

摘要： The detector has a first diode (X2) connected between an input terminal (12) for receiving an RF signal and an output terminal (13) for outputting the detection signal of the RF signal, and a second diode (X1) one side of which is connected to the input terminal through a buffer circuit (15). The other side of the second diode is connected to a constant voltage source (14). The two diodes are connected in a manner that the voltage drop across the second diode (VX1) has an opposite polarity to the voltage across the first diode (VX2).

摘要： A telephone having a display section, a key input section, and a dial memory storing a plurality of telephone numbers in association with labels representative of the names of subscribers such as individuals and companies. In a simple call origination mode, a display control reads some of the labels out of the dial memory and displays them together on the display section in a particular format which clearly shows the correspondence between keys provided on the key input section and the labels. When one of the labels appearing on the display section is selected on associated one of the keys, a call origination control originates a call by using a telephone number stored in the dial memory in association with the label having been selected.

摘要： A battery-powered radio communication apparatus is disclosed which comprises a power amplifier, a power detector for detecting the output power of the power amplifier. A supply voltage detector compares a standard voltage with the output voltage of a battery which supplies power to the power amplifier. A gain control circuit controls the gain of the power amplifier in response to the output of the power amplifier and to the output of the supply voltage detector so as to prolong by a certain time the communicable state of the apparatus.
