Title: Temperature detecting circuit for planar heat-sensitive heating element
Inventor: KUROYAMA KATSUHIKO
IPC: G05D23/24
Filed: 1988-12-22
Abstract: PURPOSE:To equalize the temperature detecting sensitivity among parts of a planar heat-sensitive heating element by applying the voltage having a 180 deg.-phase deviation to one of two metallic conductors against the AC voltage applied to the other metallic conductor. CONSTITUTION:The both ends (g) and (h) of a secondary winding of an insulated transformer 9 are connected to both ends (c) and (d) of a sensor conductor Tc of a temperature detecting element SE' respectively. A ZCT 10 of a sensor current detecting circuit 8 interlinks between the end (h) of the secondary wiring of the transformer 9 and the end (d) of the conductor Tc. Therefore the waveforms both ends (a) and (b) of a heater element H of a heat-sensitive heating element SE and the waveforms of both ends (c) and (d) of the conductor Tc are equal to the waveforms of both ends (e) and (f) of a primary winding of the transformer 9 and the waveforms of both ends (g) and (h) of the secondary winding respectively. That is, the waveforms having the same wave height and a 180 deg.-phase deviation are obtained. As a result, the uniform potential differences are always secured at any part between the element H of the element SE and the conductor Tc for the element SE'. Thus the equal sensitivity is secured at any part of the element SE.
