Title: Current monitoring device for relay contact point
Inventor: NOZU MASAHIRO
IPC: H01H9/54
Filed: 1986-10-31
Abstract: PURPOSE:To securely detect the conduction state of a relay contact point by detecting a current which flows to the relay contact point from the transmission of light projected on a magneto-optical sensor. CONSTITUTION:When auxiliary relay contact point 1 and 2 are broken and an auxiliary relay 3 is excited, currents flow to the contact points 1 and 2. At this time, when the contact resistance of the contact point 1 is larger than that of the contact point 2, the current flowing to the contact point 1 is weak. Mixed light from a measurement processing part 6, on the other hand, a illuminates magnetic sensors 4 and 5 through an optical fiber 14 and becomes single light. The single light is polarized with the magnetic force of a current 6 flowing through a cable run 10 and the polarized light enters the processing part 6 through an optical fiber 15, so that the conduction states of the contact points 1 and 2 are detected. The light passing through the optical fiber 15 is not affected by electromagnetic induction, so even if the light is weak, the processing part 6 securely detect the light. Therefore, even if the current flowing to the contact point 1 is weak, the conduction state of the contact point 1 is securely detected without being affected by noise.

IPC: G11C11/34
Filed: 1985-11-20
Abstract: PURPOSE:To reduce the current density of a word line and to reduce the voltage drop of the work line by decentralizing the 2nd stage transistors (TRs) of a Darlington driver into plural TRs. CONSTITUTION:A cell area of an ECLRAM is divided into plural areas (n), subword lines are provided to respective divided cell areas to connect memory cells in the dividing cell areas, the 2nd stage TRs of the Darlington-connection driver are decentralized into plural TRs Qi1-Qin, the outputs of 2nd stage TRs are respectively connected to the subword lines W<+>, and a discharge current source is formed in each divided cell area connected to each subword line W<+>. Since the discharge current source is formed in each divided cell area even if the capacity of the ECLRAM is increased, current flowing into each word line is not increased.

Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To reduce size by providing magnetic bodies for attracting or repelling a rotor yoke which is coupled directly with an output shaft opposite to a partial angular region of the rotor yoke and imparting a side pressure to the output shaft thereby preventing rattling of the output shaft and lowering the height of an apparatus. SOLUTION: A drive magnet 10 is fixed to the inner circumferential wall of a rotor yoke 11 opposite to the outer circumference of a core 13 and magnetic bodies 17 are placed, at a prescribed interval, in a region of rotary angle 180 deg. of the rotor yoke 11 on a motor base 16 at a position facing one end face of the drive magnet 10. The drive magnet 10 generates a force for attracting or repelling only a part of the magnetic body 17 in the thrust direction and an output shaft 12 is subjected to a side pressure in one direction. Since one side part of the output shaft 12 is pressed constantly against one side face in the clearance of a bearing and does not move in the radial or thrust direction, the output shaft does not rattle and the structure can be simplified.

Title: Toner shortage detector
Inventor: YAMANAKA HIROMICHI
IPC: G03G15/08
Filed: 1989-10-04
Abstract: PURPOSE:To prevent a malfunction even if an AC current is not temporarily outputted and to detect toner shortage by delaying the toner shortage detection timing. CONSTITUTION:When the quantity of toner 4 in a developing unit is more than the quantity in detecting the toner shortage, a voltage outputted from a comparator 8 goes to an HI level, and the voltage of this level is held in a capacitor 14 via a charging resistance 11 and a diode 13 at this time. When the quantity of toner 4 is decreased and VDC becomes smaller than VS, the output of the comparator 8 goes to a LOW level and a detecting voltage charged to the capacitor 14 is discharged via a discharging resistor 12. Then, the voltage of LOW level is inputted to a display circuit 9, which displays the shortage of the toner. At this time, if the value of the discharging resistance 12 is far greater than one of the charging resistance 11, the detecting voltage is held in the capacitor 14. Thereby, even if the AC current is not temporarily outputted, the display circuit 9 does not display the shortage of the toner erroneously.
