Abstract: A producing sequence is constituted by a plurality of tasks. To manage production, a task difficulty level of a task within the producing sequence is evaluated. INPUT, PROCESS and OUTPUT skill categories are determined by categorizing a skill required for human resource in charge of the task according to cognitive science. The INPUT skill category is related to cognition of outer field information or acquisition of cognitive information. The PROCESS skill category is related to thinking or decision. The OUTPUT skill category is related to behavior or action. The task is evaluated with the INPUT, PROCESS and OUTPUT skill categories, to obtain respectively difficulty ranks. The task difficulty level is determined by processing the difficulty ranks in combination according to overall processing. Also, a risk diagnosis is provided, in which an error influence level of a predictable error of a task within a producing sequence is assessed.

Abstract: A drive current Ip used to control the light output from a laser diode LD is controlled by using an output Vsft from a level shift circuit 3. By inserting the level shift circuit 3 between a drive source (V+) and a switch buffer 5, the lower limit (V+)−(V−) of the drive voltage in the circuit is lowered to enable the laser diode drive circuit to be driven at a lower voltage and to achieve a reduction in power consumption.

Abstract: The inverter functioning as a comparator, dummy inverter having the same electric characteristics as the inverter, and control circuit are provided. Vth detecting input voltage output from the control circuit is input into the dummy inverter, Vth detecting output voltage output from the dummy inverter is input into the control circuit, and the threshold voltage of the dummy inverter is detected. The threshold voltage of the inverter is controlled by controlling the back gate voltages of the MOS transistors of the dummy inverter and the inverter in such a manner that the threshold voltage of the dummy inverter coincide with an external reference voltage.

Abstract: In a method for deciding the level of an input signal, positive and negative signals are provided in response to the input signal. A peak of the positive signal is detected to provide a positive-peak value. A peak of the negative signal is detected to provide a negative-peak value. The positive signal and the negative-peak value are combined to provide a first combination signal. The negative signal and the positive-peak value are combined to provide a second combination signal. The first and second combination signals are compared to provide an output signal of zero or one.
