摘要:
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.

When a work is set on a hot plate and a heat treatment is started and the like, an addition waveform of a target temperature is formed based on a previously formed data of an adjustment value, and a temperature is controlled by adding the addition waveform to the target temperature SP, and with the data of the adjustment value, the variation in temperature of the work is prevented using an interference matrix showing a relation between the target temperature SP and the temperature of the work.

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.

The invention is configured such that a distance estimation device estimates a distance between a hot plate as an object to be treated and a work, with respect to which the work is placed to be thermally treated, based upon information on temperature of the hot plate such as an absolute value of inclination of the temperature of the hot plate, and a determination device compares the estimated distance with a threshold to determine the presence or absence of abnormality.

A customer submits a service application by accessing the home page of a service provider through a personal computer 3, and transmits the data including the operation amount and the control amount of a temperature controller 4 to a server 2 of the service provider. The server 2 accumulates the received data, and in accordance with the contents of the received service application, processes the accumulated data and provides the services of calculating the control parameter for the temperature controller 4, producing a model of the object of control and making a diagnosis by checking for a temperature control fault.

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 communication system includes: a transmitter adapted to transmit a synchronizing clock and serial data synchronous with the synchronizing clock over a line at low amplitude; and a receiver adapted to receive the serial data and synchronizing clock from the transmitter. The receiver includes an amplifier adapted to amplify the received synchronizing clock of low amplitude to restore the clock to its original amplitude, a latched comparator adapted to latch the received serial data in synchronism with a reproduction clock, and a phase-locked circuit.
