Title: Image forming device
Inventor: HONDA KENJI
IPC: G03G15/20
Filed: 1993-10-15
Abstract: PURPOSE:To form an image onto both the ordinary paper and the offset paper without causing the failure by raising the fixing control objective temp., widening the image forming area, and conducting an intermittent operation at the time of consecutive image forming. CONSTITUTION:In the case of the offset mode, after setting the delay time (T1 5sec), the temp. of the heater lamp is lowered to 160 deg.C (standby objective temp. 01) by stopping the power supply to the heater lamp for the prescribed time. Then, the print request for the second paper sheet is set, the attention signal (change from the low level to the high level) is outputted, series of the printing operation is completed and it again becomes the standby state. Consequently, at the time of the offset mode, the complete one-sheet-intermittent mode, in other words, even at the time of consecutive print, the next print is performed while lowering the temp. of the fixing device to the temp. 01, that is, 160 deg.C by the delay time T1. Thus, the fixing quality corresponding to the offset paper is improved since the overshooting can be utilized for every one of the sheet.

Title: Gas cut-off device
Inventor: SAKAGUCHI YUKIO
IPC: F16K17/36
Filed: 1993-10-15
Abstract: PURPOSE:To eliminate the erroneous cut-off for the leak within the specification of a cut-off valve and prevent the exhaustion of a battery by judging the anomaly of the cut-off valve on the basis of the flow-rate measurement signal, time measurement signal, and the valve state memory signal, during the cut-off of the cut-off valve. CONSTITUTION:A flow-rate measuring means 3 measures the gas supply quantity for each unit measurement volume v(l). While. a cut-off valve 4 cuts off the gas supply again when the leak flow rate q (l/h) due to the cut-off disorder in the gas supply exceeds an allowable leak quantity qs (l/h), the gas supply is cut off again. A valve state memory part 7 in a control part 10 memorizes the existence of the cut-off operation of the cut-off valve 4. Further, a timer 9 measures a prescribed time t (h), accompanied with the input of the flow-rate measurement signal. Further, a cut-off anomaly judging part 8a outputs a cut-off signal when the flow rate measurement signal up to the input of the measurement completion signal in a prescribed time t(h) in the cut-off state of the cut-off valve 4 satisfies the following equation: (k-1) v/t=qs<=q, while if q<=qs, a measurement prohibition signal is outputted.
