Title: Detecting circuit for runaway
Inventor: MATSUBARA AKIRA
IPC: G06F11/30
Filed: 1985-04-17
Abstract: PURPOSE:To detect completely the abnormal output of a specific port by integrating the output of the specific port of a microprocessor MPU with no saturation and applying this output to a hysteresis comparator. CONSTITUTION:The output A of an I/O port of a MPU is integrated with no saturation by an integration circuit R'C' having a large time constant. Then this output signal B of integration is supplied to a hysteresis comparator CMP1'. The CMP1' sets upper and lower levels of reference voltage ref1/ref2 within the amplitude of the output B when the signal A has a normal output. The amplitude of the integration output B or the average level is different from those normal values in case the output signal A of the I/O port produces the output having different frequency or duty from those of a normal state. Therefore, the CMP1' stops the output variation when the signal B gets out of the range ref1/ref2 set by the CMP1'. A program runaway is decided if said stop state of the output variation lasts for a fixed period of time. Thus the MPU is reset by a CMP2.

Title: Ink jet recorder
Inventor: NOJIMA TAKASHI
IPC: B41J2/01
Filed: 1989-03-31
Abstract: PURPOSE:To accelerate fixation of an ink and restrain power from being wasted by controlling the quantity of power applied to a heating means for a recording medium, based on the atmospheric conditions for a recording head detected by a detecting means. CONSTITUTION:A recording head 10 is moved relative to a recording medium in a recording direction indicated by an arrow, while an ink is selectively ejected from ejecting ports 3 toward the recording medium, whereby recording is performed. A recorded part of the recording medium immediately after the ejection of the ink is heated by fixing heater 1, so that fixation of the ink can be accelerated. When the atmospheric temperature in the vicinity of the head detected by a temperature sensor 7 is low, the separation of heating pulses is shortened to increase the quantity of power supplied to the heater 1. When the detected temperature is high, the pulse separation is prolonged to reduce the quantity of power applied to the heater 1. Thus, wasting of power at the fixing heater can be reduced.
