    • PROBLEM TO BE SOLVED: To preferentially perform reception processing to a serving cell in a connection environment to a plurality of cells. SOLUTION: A mobile terminal communicates with the plurality of cells including the serving cell, and performs at least one control of (a) a first control for detecting a path for the serving cell more preferentially than other cells, (b) a second control for assigning a path detected in the serving cell preferentially over paths detected in other cells to fingers, and (c) a third control for adjusting reference frequency of the mobile terminal so that the reference frequency is approximated to reference frequency of a base station controlling the serving cell compared with a case in which reference frequency is approximated to reference frequencies of base stations controlling the plurality of cells including the serving cell.

    • PURPOSE:To enable an incoming subscriber to re-call for a prescribed period of time even after the hand set is hooked on in a re-calling system where a call is received again from an outgoing subscriber after the end of talking. CONSTITUTION:A telephone set 1 is provided with a telephone function control part 7 which contains a dial function for connecting an exchange, a speech transmission/reception network function, a call signal function, etc., a control part 8 which controls various telephone functions, and an external speaker 3 which transmits a control signal to the part 8 with the hook-on 4 of a handset and broadcasts the received voices to an outside in the control of the part 8. An off-hook timer 6 is added to start a counting action as soon as an incoming speaker is set in an on-hook state after the talking and keeps an off-hook state for a prescribed time together with a hooking button 5 which hears the busy tone sent from the speaker 3 during the working of the timer 6 and gives the manual control to the timer 6. Then an originating speaker calls again the incoming speaker who is kept in an on-hook state.

    • PURPOSE:To provide a casing shielding structure in a novel electromagnetic shielding structure in an electronic apparatus of a communication apparatus, etc., in which an electromagnetic shielding effect is not reduced even in a case where a transparent resin plate, etc., are employed for protection of a front surface of the casing. CONSTITUTION:In an electronic apparatus such as a communication device constructed by accomodating a purality of slide-in-units parallely in a metal casing through a front opening in the metal casing, the front opening in the casing is substantially closed and covered with a transparent resin cover including a conductive mesh 6 serving as an intermediate layer. A screw hole 10 is formed at a predetermined location on the cover 2 through the conductive mesh 6, and the tip end of a conductive tapping screw 14 threaded into the screw hole 10 is exposed to the surface of the cover, and further through the exposed tip end of the tapping screw the conductive mesh 6 is made electrically conductive with the casing.
