    摘要: A portable telephone apparatus includes a reference frequency generating section capable of suitably changing frequency accuracy of an output signal in accordance with an input control voltage, and a high-accurate reference frequency generating section having accuracy for a temperature change extremely higher than that of the reference frequency generating section and in which output frequency accuracy thereof changes only within a range of prescribed values. A determination device determines whether or not frequency accuracy of an output signal from the reference frequency generating section meets the prescribed value. A selector selects an output signal from the reference frequency generating section in a case that a determination result of the determination device meets the prescribed value, and selects an output signal from the high-accurate reference frequency generating section in a case that a determination result of the determination device does not meet the prescribed value.

    摘要: In the disclosed control system, loops of 1st path and 2nd path are formed connecting an active CPU unit and each of RIO units, the direction of data frame transfer through the loop of 1st path being opposite to that of the data frame transfer through the loop 2nd path. Reflective electro-optical transducer modules are used in the RIO units which are connected with the active CPU unit so that a standby CPU unit can also be connected. Further, the loop of 1st path and the loop of 2nd path are formed connecting the standby CPU module and each of the RIO modules. The data frame transfer directions through the loops connecting the active CPU unit and each of the RIO units are opposite to the data frame transfer directions through the corresponding loops connecting the standby CPU unit and each of the RIO units.

    摘要: An NMOS capacitor 13 and a PMOS capacitor 18 for pumping up are connected in series to an output line 12. In middle point voltage control circuit 20, a power supply line at VCC is connected via a PMOS transistor 21 to the anode of a reverse-flow preventing diode 22 and the node of voltage VM, the cathode of the diode 22 is connected via an NMOS transistor 23 to a ground line, and control signals *BIN and AIN are provided to the gate electrodes of the transistors 21 and 23, respectively, in response to an address transition detection signal AT. An end point voltage control circuit 30 is connected between the gate electrode of the NMOS transistor 23 and one end of the PMOS capacitor 18, and is equipped with inverters 31 and 32 connected in series. In an initial state, VM is at 0V and VE and VOUT is at VCC. Next the node of VM becomes a floating state and VE is lowered to 0V. Finally the node of VM is raised to VCC to boost VOUT from VCC up to VCC(2+.alpha.), where 0
