The digital signal within the circuit 11 is converted into the analog output voltage 15 by a D/A converter 12 and supplied to a voltage control oscillator 5 to control the oscillation frequency of a reference signal 7. This controlled signal 7 is fed back to the circuit 1 and compared with the sink byte signal in terms of phase. A sampling signal 14 is supplied to the circuit 11 for a sink byte period by a synchronism control signal 8 and a gate circuit 13. Therefore the circuit 11 replaces its holding contents in response to the input fed from the converter 10 for a sink byte period.

Title: Method and device for detecting abnormality of temperature control system
Inventor: HAJIMA KAZUYUKI
IPC: G05D23/19
Filed: 1989-07-31
Abstract: PURPOSE:To detect the abnormality with high accuracy by setting plural reference temperatures for detection of the abnormality in accordance with each control target temperature and shifting those reference temperatures with each other via a time series temperature changing curve. CONSTITUTION:The temperature control reference voltage VW set at the anode side of a voltage dividing resistance R4 is switched to the reference voltage Vt corresponding to the fixing control target temperature St. Then the shift control is carried out to the temperature St based on the signal received from a comparator 1. At the cathode side, the weight reference voltage V2 is shifted to the fixing abnormality detecting reference voltage V1 by the voltage discharge of a time constant circuit 5 via a time series voltage changing curve V3 (temperature curve T3) with gradual reduction of voltage carried out in response to an RC constant after the change of the reference voltage owing to the circuit 5 set between the cathode and a comparator 2. Thus it is possible to shift to a fixing action while performing a prescribed abnormality detecting action even in a shift mode.
