Filed: 1990-11-07
Abstract: PURPOSE:To prevent the danger of other paper in an image forming apparatus entering into a fixing device and being fired by determining whether or not there is any paper in the fixing device when the temperature of the fixing device rises abnormality, and stopping feed of other paper after discharging paper in the fixing device. CONSTITUTION:When an abnormal temperature rise of a fixing heater 15 is detected a printer inhibits paper feed action and detects the signal of a sensor 19 for paper before fixing and, if the signal detected is active, performs forcible paper discharge action since then paper remains in a fixing device 18. When the detected signal of the sensor 19 becomes inactive, the signal of a sensor 20 for paper after fixing is detected and paper discharge action is continued until the signal becomes active, and paper remaining in the device 18 is forcibly discharged. If the detected signal of the sensor 19 is inactive as the abnormal temperature rise of the device 18 is detected, the detected signal of the sensor 20 is verified and, if the signal is inactive, a device determines that there remains no paper in the paper 18 and then forcible paper discharge action is not carried out and at the same time paper feed is stopped and feeding of paper into the device 18 is inhibited.

Filed: 1987-11-30
Abstract: PURPOSE:To flatten glass layer by heat treatment and to reduce adverse influence to as semiconductor element or wiring by coating the semiconductor element or wiring by a glass layer where chemical compound including boron and fluorine were ion-implanted. CONSTITUTION:A semiconductor element or a wiring 7 is formed on a substrate 1. The semiconductor element or the wiring 7 is coated by a glass layer 8a where a chemical compound including boron and fluorine was ion-implanted. The glass layer 8a is flattened by heat treatment. Then, with the glass layer 8a, temperature for heat treatment for flattening can be reduced as compared with the conventional approach which does not include boron and fluorine.

Title: Pull-down circuit
Inventor: WATANABE KATSUMI
IPC: G06F15/78
Filed: 1991-11-18
Abstract: PURPOSE:To minimize power consumption at signal input by turning off a P-channel MOS-FET at the signal input so as to interrupt the connection between a source electrode of an n-channel MOS-FET and ground. CONSTITUTION:A FET 23 is in the floating state at power-on and the on/off state is not fixed, then a leakage current from a drain electrode of the FET 23 to a source electrode flows. Thus, a point A between a source electrode of the FET 22 and a drain electrode of the FET 23 reaches an L level being a ground level and a potential at a point B at the equal potential of an input terminal 21 is fixed to an L level. Moreover, when an H level signal of a voltage VDD is inputted to the terminal 21, the FET 23 is turned off, the connection between the point A and ground is interrupted, the FET 22 is always turned on and the potential at the point A reaches an H level. In this case, the FET 23 is completely turned off and no through-current flows at all. Thus, useless power consumption is avoided.
