A mobile terminal capable of being connected to a charger according to an exemplary embodiment includes a notification unit that notifies predetermined information by using at least one of an image, lighting, a sound, and a vibration, a charger detection unit that identifies a charger connected to the mobile terminal, and a control unit that controls the notification unit so that the notification unit provides a different notification to a user according to a type of the charger connected to the mobile terminal.

Mobile terminal, control method thereof, and non-transitory computer readable medium storing control program

A mobile terminal according to an exemplary embodiment includes a display unit that displays predetermined information, a display control unit that controls the display unit, an input unit that allows input of predetermined information, and a setting unit that sets the display unit to a first low brightness display state, in which the first low brightness display state displays the display unit with low brightness. When the setting unit sets a display state of the display unit to the first low brightness display state, the display control unit controls the display unit to display only predetermined information that should be displayed while controlling the display unit to display a background screen of the display unit with lowest brightness or brightness near the lowest brightness, which is first low brightness, at the time of displaying the predetermined information on the display unit.

Mobile terminal, display control method thereof, and non-transitory computer readable medium storing display control program

A rotation control device capable of suppressing vibrations of a rotation unit produced due to changes in weight unbalances of the rotation unit. On a disc rotation control device 2, made up of a driving shaft 8 rotated along with an optical disc 90, a turntable 9, a motor rotor 10 and a magnet 15 mounted on the motor rotor 10, balancer members 6, 7 are mounted so that the balancer members 6, 7 are rotatably supported on the driving shaft 8. The disc rotation control device 2 causes rotation of the rotation unit such that a synthesized center of gravity of the rotation unit offset from the center of rotation by the unbalances of the optical disc 90 and the balancer members 6, 7 will coincide with the center of rotation.

Rotation control apparatus

A magnet is provided which holds spherical balancers in the central portion of a rotor when the rotation of the rotor is stopped. When rotations of the rotor is started, a larger torque T.sub.0 is transmitted from the rotor to the balancers. Thus, the balancers quickly start rotating. When the rotor rotates at high speed, the centrifugal force separates the balancers from the magnet and moves the same to the outer wall portion of the rotor. At this time, a torque T.sub.0 which is transmitted from the rotor to the balancer is reduced so that the balancers are moved in the circumferential direction. Thus, the automatic aligning operation is performed. The number (n) of the balancers is made to be a value obtained by the following equation:

In a mobile telephone set, a speech coder is provided for converting an analog speech signal to a digital speech signal. A voice activity sensor determining whether the analog speech signal is present or not. A storage level detector determines the amount of a data signal waiting for transmission from a non-telephonic communications apparatus. A switching control logic determines the rate for the speech coder according to the outputs of the voice activity sensor and the storage level detector. When the analog speech signal is present and the amount of the waiting data signal is zero, the data rate is set at a high rate and a digital speech signal from the speech coder is transmitted along with an indication of the high data rate. When the analog speech signal is present and the amount of the waiting data signal is non-zero, the data rate of the speech coder is set at a rate which is lower than the high data rate and is variable in accordance with the amount of the waiting data signal and the digital speech signal from the speech coder and the data signal from the non-telephonic communications apparatus are transmitted along with an indication of the variable data rate. When the analog speech signal is absent and the amount of the waiting data signal is non-zero, the data signal from the apparatus is exclusively transmitted.

Telephone apparatus for multiplexing digital speech samples and data

In a digital cordless telephone system including master and slave radio stations that are operable in response to first and second frame synchronization signals synchronized with each other to produce first and second TDMA signals in the form of radio signals, respectively, a timing signal whch is produced on the basis of the first frame synchronization signal by the master radio station is transmitted to the slave radio station through a signal line to synchronize the slave radio station with the master radio station and is received by the slave radio station after lapse of a time delay determined by a length of the signal line. The timing signal is delayed in the master radio station by a single period of the first frame synchronization signal to produce the first TDMA signal synchronized with the delayed timing signal while the timing signal received with the time delay by the slave radio station is timed by the second frame synchronization signal to produce an output synchronization signal synchronized with the second frame synchronization signal and to obtain the second TDMA signal timed by the output synchronization signal. As a result, the first and the second TDMA signals are produced at an instant coincident with each other. The timing signal may be a TDMA frame synchronization signal.
