摘要:
A target value processing unit, includes: an input section to which a target value signal showing a target value of a control process is inputted; a target value shaping unit shaping the target value signal inputted to the input section, into a signal form which is proper for a control treatment of a regulator implementing the control process; and an output section outputting to the regulator a shaped target value signal which is shaped by the target value shaping unit. The target value processing unit realizes the high-level control process without improving the regulator.

In a method of controlling the temperature of a target object by measuring to obtain detected temperatures at a plurality of measurement positions and controlling a processing device such as a heater such that each detected temperature will match the corresponding one of target temperatures set for the processing device, a preliminary step is taken to determine the degrees of interference at the measurement positions by varying the target temperatures and the degrees of interference thus determined are used to correct the set target temperatures or the detected temperatures.

A power switch and connector that are conventionally included in a body are formed in spaces created at the outer ends of the shafts of hinges other than the body and a display, whereby the body is thinned. Electronic device comprises a body, a display, and a hinge that joins the body and display so that they can be freely opened or closed. A power switch is formed at an end of the shaft of the hinge. Furthermore, the electronic device comprises the body, the display, and another hinge that joins the body and display so that they can be freely opened or closed. A port of a connector opens at an end of the shaft of the hinge.

An analog signal, for example, a video signal is divided into a high frequency signal and a low frequency signal by a high-pass filter and a low-pass filter. A high speed analog-to-digital converter (ADC) converts the high frequency signal to a first digital code while a low speed but high precision ADC converts the low frequency signal to a second digital code. A synthesizer combines the first and second digital codes and outputs a digital code as the result of the conversion. Therefore, analog-to-digital conversion with a high speed, high precision, and high resolution can be realized.

A device to prevent reverse current flow includes a diode connected between a power supply and a load. A switching device, connected in parallel with the diode, has a power loss that is smaller than that of the diode. A low-loss current detector, arranged to turn the switching device on and off, includes a DC current detector and a comparator. The comparator compares the detected DC current value with a threshold value for an operating current and generates an output signal that determines when the switching device should be turned on or off.

A phase comparator includes a first signal input terminal supplied with a reference signal, a second signal input terminal supplied with an input signal to be compared with the reference signal, a first gate circuit having a pair of input terminals and an output terminal, one of the pair of input terminals of which is connected to the first signal input terminal, a second gate circuit having a pair of input terminals and an output terminal, one of the pair of input terminals of which is connected to the second signal input terminal, a first bi-stable circuit having set, reset and output terminals, the set terminal of which is connected to the output terminal of the first gate circuit, a second bi-stable circuit having set, reset and output terminals, the set terminal of which is connected to the output terminal of the second gate circuit, and first and second gate control circuits connected between the other input terminals of the first and second gate circuits and the output terminals of the first and second bi-stable circuits operative to open one of the first and second gate circuit alternately. The output signal proportional to the phase difference between the input signal and the reference signal is produced at one of the output terminals of the first and second bi-stable circuit in accordance with whether the input signal phase-advances more than the reference signal or not.
