Abstract: PURPOSE:To linearly execute the rise and the fall, and to change a clamp voltage to change the rise/fall speed (inclination) by clamping an inversion input terminal of an operational amplifier of a voltage output amplifier to a small voltage, at the time of rising and falling an output voltage. CONSTITUTION:In a rise inclination setting circuit 24, a rise inclination set value set to a register 26 is converted to a positive analog voltage of a rise inclination setting D/A converter 27, and its positive voltage is applied to a rise clamping circuit 28. To an output voltage of the rise clamping circuit 28, a voltage of an inversion input terminal 34 is clamped. Accordingly, when an absolute value of this clamp voltage is set to a small value in advance, a voltage of an output terminal 13 rises at a speed corresponding to this clamp voltage, and it is continued until the output voltage of the output terminal 13 becomes a value corresponding to an output voltage of a voltage setting D/A converter 11. When the output voltage of the rise inclination setting D/A converter 27 is made high, the rise of the output terminal 13 comes to quick, and when the output voltage is made low, the rise comes to slow.

Filed: 1992-11-27
Abstract: PURPOSE:To improve the bus availability when a reading request is received from a bus master. CONSTITUTION:When a bus master 11-1 acquires the using right of a bus 12 and gives a reading request to a reading device 13, a reading part 131 of the device 13 starts to read an equipment 14 and also returns a re-execution/bus open request to the master 11-1.

When the data of first two times are received from the equipment 14, an estimating part 132 calculates a reading end time Tre based on the transmitting time interval of data and the transmitting frequency of the remaining data. Meanwhile an estimating part 133 estimates the time Tn when a rereading request is given from the master 11-1 if the re-execution is requested when the rereading request is received from the master 11-1. Then a deciding part 134 compares Tre with Trn and suppresses the re-execution request given from the part 131 when Tre<Trn is satisfied.
