Title: Paper feeder
Inventor: AZUMA YUICHIRO
IPC: G03G15/00
Filed: 1988-03-16
Abstract: PURPOSE:To make paper feeding inexpensive by forming a notch face on the circumference of a pickup roller extending over the full length of the axial direction, feeding the topmost paper to space between a feed roller and a reverse roller each time the said pickup roller rotates, and forming a clearance between the notch face and the topmost paper at time of the stopping. CONSTITUTION:When a pickup roller 10 rotates in an F direction and a corner part 10c of an arcing surface 10b comes into contact with the topmost sheet of paper P, the topmost paper enters its conveyance in an A direction. When it is reached to a nip part between a feed roller 4 and a reverse roller 5, a feed clutch is turned off, and the pickup roller 10 has a notch face 10a opposite to the topmost paper, forming a clearance S between them, and it comes to a stop. In this case, if more than two sheets of the paper A are doubly fed, torque being transmitted to the roller 5 from the roller 4 is transmitted via small frictional force by paper-to-paper contact, so that the transfer torque becomes less than the specified torque of a torque limiter, therefore the paper at the downside is put back in a cassette by way of the clearance S.

Title: Latch-up detection circuit
Inventor: ISHII HIROYUKI
IPC: H03K19/003
Filed: 1993-03-19
Abstract: PURPOSE:To detect a latch-up in any IC accurately by connecting the cathode of a diode to the power supply terminal of each IC, connecting an anode to one resistor, and then connecting the detection terminal of the resistor to the power supply with the connection point as the detection terminal. CONSTITUTION:When all ICs 1 operate normally, the power supply terminal of the ICs 1 is nearly equal to a power supply voltage +Vcc and the voltage of a detection terminal 6 is also equal to the power supply voltage. When the ICs 1 receive a high energy radiation and at least one ICs 1 result in latch-up, the ICs are short-circuited and the power supply terminal of the ICs 1 are connected to the ground potential. Therefore, a forward voltage is applied to a diode 5, thus allowing current to flow and the potential of the detection terminal 6 to be also connected to the ground potential. Therefore, the voltage of the detection terminal 6 changes from the high level of the power supply voltage to the low level of the ground potential and then is output as a latch-up detection signal. Also, even if the voltage of the detection terminal 6 is reduced to a low level, the power supply terminal voltage of other ICs 1 where no latch-up is generated, us not reduced and continues normal operation since an inverse voltage is applied to the diode connected to the ICs.
