Filed: 1990-03-01
Abstract: PURPOSE:To form a simplified bus conversion circuit by deciding the input/ output direction of a data bus by comparing the output level of a host data bus with that of a slave data bus. CONSTITUTION:In the control of the data bus, a directional control circuit 6 immediately checks the bit levels of the host data bus and the slave data bus by an already activated access effective instruction signal and decides an access direction. Data is read out from an I/O slave side in a read operation, and when at least one or more zeros exist, the direction control circuit 6 validates the left direction tristate element of a data bus buffer circuit 5 by activating a left directional instruction signal Lo. Also, in a write operation, since an I/O slave bus keeps a level 1, the right directional driving of the circuit 5 can be validated by activating a right directional instruction signal Ro if at least one or more levels 0 exist in the data out of the data at a host bus side. In such a way, the simplified bus conversion circuit is obtained.

Filed: 1979-04-24
Abstract: PURPOSE:To prevent the failure signal output, by delaying the renewal of memory means for the time for overlapping and eliminating the uncertain output of the memory means accompanied with renewal. CONSTITUTION:The memory circuit 4 is renewed with the output of the delay circuit 11. By comparing the output of the circuit 4 with the input signals 1-1, 1-2, 2-1, 2-3 at the comparison circuit 10, the coincidence signal indicating the end of renewal of the circuit 4 is obtained as the output. This coincidence signal and the inverting delay signal inverting the output of the circuit 11 at the inversion circuit 11 are input to the gate circuit 14 to obtain the gate signal of the gate circuit 6. The output of the circuit 6 is input to the expansion circuit 8 for expansion, allowing to output the old state output 9-1 before the renewal of the circuit 4 and to obtain the new state output 9-4 after that. By tying the outputs of the circuits 7, 8, the old output 9-1 and the new output 9-4 are overlapped while the time corresponding to the delay time of the circuit 11. Before that, 9-1 only is output and after that, 9-4 only is output. Thus, the incorrect expansion signals 9-2, 9-3 accompanied with the renewal are not appeared as output.

Title: Toner detector
Inventor: KOKUBU TATSUO
IPC: G03G15/08
Filed: 1979-04-25
Abstract: PURPOSE:To make it possible to detect whether there is magnetic toner without any influence of toner contamination in a toner container by providing a relatively- movable magnet at the non-magnetic material part of the container containing the magnetic toner. CONSTITUTION:On the container wall of toner container 1 made of a non-magnetic material of an Al plate, etc., permanent magnet 6 is supported by a non-magnetic material such as phosphor bronze and this magnet 6 is movable to the position through electromagnet 3. Then, lead switch 8 is put into operation by magnet 5. When container 1 contains a sufficient volume of toner 2, flowing a current through electromagnet 3 to repulse magnet 5 forces magnet 5 to come close to the wall of container 1 and even if the current supply to electromagnet 3 is cut off in this state, magnet 5 stays sticking to the wall of container 1 by the magnetic suction force of toner 2. At the time when toner 2 lessens, on the other hand, cutting off the current supply to electromagnet 3 allows magnet 5 to return the electromagnet 3 side by its weight because of no suction of toner 2 and at this time, magnet 5 put lead switch 8 into operation to detect the position of magnet 5.

Abstract: PURPOSE:To suppress the fluctuation of a reference potential due to the fluctuation of a power source voltage by outputting the reference potential from a serial junction between a non-linear saturated resistor serially connected between a higher voltage source and a lower voltage source, and a linear resistor. CONSTITUTION:A resistor 2 having a linear voltage/current characteristic is connected between a lower voltage source Vss and an output terminal Ref, and a saturated resistor 3 having a non-linear voltage/current characteristic by which the currents are saturated to a prescribed value according to the increase of the voltage is connected between a higher voltage source VDD and the output terminal Ref. In such constitution when the potential of the lower voltage source Vss is a ground potential, and the potential of the higher voltage source VDD is V1(V1>0), a reference voltage VR1 is expressed by VR1={R2/(R+R 2)}XV1. At this time, the resistance value of the resistor 3 is defined as R1, and the resistance value of the resistor 2 is defined as R2. Then, the fluctuated amounts of the currents running between both the power sources against the fluctuation of the power source potential are reduced by the non-linear saturated resistor, so that the fluctuation of the reference potential can be suppressed.
