Filed: 1993-09-08
Abstract: PURPOSE:To instataneously ground a terminal just after a fuse-cutting by providing a grounding circuit at the terminal between a fuse for changing over a signal and a resistor for reducing power comsumption in a reduntant circuit used in a semiconductor device. CONSTITUTION:Usually, a terminal (a) is impressed with the voltage of power supply Vcc via a fuse 1 to be a high level and the output terminal (b) of a CMOS inverter circuit 3 is in a grounded state to be a low level. When power supply Vcc becomes a high voltage and the fuse is cut-off, the terminal (a) has to become the low level just after the fuse cutting-off, however, the switching time is needed because a resistor 2 whose one end is grounded is a high resistance and its time-constant with a stray capacity 6 is large. When a large voltage is impressed on an input terminal 5 and the voltage becomes higher than a threshold voltage, a transistor 3 is turned to on by providing a grounding circuit 4 having plural numbers of transistors having a prescribed threshold voltage. Thus, the terminal (a) is turned to be in a grounded state instantaneously to be the low level and the changeover to standby memory cells is performed.

Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To suitably load paper sheets by judging bent direction of paper sheets based on a paper discharge mode and optimizing a chance for controlling interval of a paper passage. SOLUTION: In a case of a paper discharge mode for regulating a distance between the upper surface of a stacker table 1 or the top surface of loaded paper sheets 12 piled on the stacker table 1 and a guide member 10 to a narrow distance, because paper sheets highly tend to be discharged in the state that they are bent downward, a load failure that the tip of the discharged paper sheet, in reaching ground, interferes with the top surface of the loaded paper sheets 12 tends to occur. For preventing these, the top surface of the loaded paper sheets 12 is set as high as possible to stabilize paper discharge operation.  In a case of a paper discharge mode for regulating the distance to a wide distance, because the paper sheets highly tend to be discharged in the state that they are bent upward, the top surface of the loaded paper sheets 12 is set as low as possible to stabilize paper discharge operation. Thus, by judging the bent direction of paper sheets, a chance for controlling interval of the paper passage is optimized.
