Title: Temperature automatic compensation constanttime delay circuit
Inventor: KUUUSU CHIYAN
IPC: H03K5/13
Filed: 1990-10-15
Abstract: PURPOSE: To obtain an integrated time delay circuit, which does not sense temperature variation and consume any DC power by composing of a reference current source, a polysilicone resistor and at least one time delay control circuit. CONSTITUTION: A constant delay circuit 10 is composed of a polysilicone resistance 16 and a time delay control circuit 14. Then a reference current from a reference current source 12 is utilized to accurately charge and discharge a capacitive load formed of a MOS transistor M5 in the control circuit 14, so that a desired constant time delay is obtained. In this case, a current flowing through the polysilicon resistor 16 has a positive temperature coefficient, and the current is compensated with a current flowing through a MOS transistor MN2 having a negative temperature coefficient. Consequently a reference current IREF1 flowing through a P-channel transistor MP2 becomes a stable current which does not sense temperature variation.

Abstract: PURPOSE:To shorten a standby period from the time when a main power source is turned on to the time when an initial copying action starts by providing a temperature detector measuring the temperature of a fixing part in the vicinity thereof and passing paper through the fixing part several times according to the measured temperature. CONSTITUTION:In response to the fixing part measurement temperature Tb from the temperature detector 5 provided in the vicinity of the fixing part 4a, the already toner-transferred paper passes through the fixing part 4a several times. If the temperature is low, for instance, the passage frequency is increased, whereas if the temperature is relatively high, the passage frequency is decreased. Consequently, the time required for the paper to come into contact with a fixing roller can be adjusted in response to a fixing temperature, whereby toner is fixed to the paper at a prescribed fixing ratio. Thus, an original is speedily copied, without waiting until the fixing roller 4 reaches a normal, prescribed temperature, and the time from the turn-on of the main power source to the start of the initial copying action can be shortened.
