Abstract: PURPOSE:To reduce the load of the system to improve the performance, by preventing the read for the instruction of the branch destination address when the condition code, which determines the branch condition, indicates no branch in the advanced control system. CONSTITUTION:In case that the conditional branch instruction which branches to address Y at the time of minus of the operation result and does not branch in other cases is executed in the advanced control system, the condition code due to execution of the instruction of three or more before the conditional branch instruction is stored in condition code register 6 when this conditional branch instruction enters into the instruction register, and the instruction of one or two before is being decoded at this time, and 1 is stored in the second and the third bits of shift register 22 if this instruction is decoded to have no influence upon the conditional branch instruction; and when the condition code of condition code register 6 is 0, AND circuit 27 outputs the output to access the address Y of cash memory 3. Consequently, since the branch address is accessed only when the branch condition is satisfied, the wasteful load is not applied to the system.

Title: Image forming device
Inventor: KUSUMOTO KEIJI
IPC: G03G15/20
Filed: 1987-03-16
Abstract: PURPOSE:To prevent defective image formation by previously prohibiting the image formation when an abnormal drop of a power source voltage arises. CONSTITUTION:A 1-chip microcomputer 55 detects the power source voltage level by A/D conversion of the voltage level inputted to an analog signal input port ANapprox.= and decides whether the image forming device is under copying operation or not when the detected value is below a prescribed level in a process for detecting the power source voltage. The microcomputer prohibits the detection of a low temp. in a fixing part if the device is under the copying operation. The computer also makes the process to stop the copying to complete the copying operation and discharges the copied paper to the outside of the machine. On the other hand, the computer makes the process to put the copying machine into a copying prohibition (standby) state so as to prevent execution of the copying on the surface of fresh copying paper when the machine is not under the copying operation. The defective copying such as defective images, defecting fixing of toners and paper jam is thereby prevented.

Title: Friction material for torque variation absorbing device
Inventor: INAGAKI ASAO
IPC: C09K3/14
Filed: 1986-03-18
Abstract: PURPOSE:To improve the operating characteristic and the durability of a device by employing a friction material mainly composed of polyamino bismaleic imid resin in a torque variation absorbing device thereby stabilizing the variation of the frictional factor to low level. CONSTITUTION:45wt% of polyamine bismaleic imid resin, 45wt% of Teflon having the grain size of 1.0-1.5mum and 10wt% of glass fibers having the diameter of 10mum and the length of 3mm are mixed to compose a frictional material. Since the frictional material employs polyamine bismaleic imid resin having excellent heat resistance as the base resin and contains Teflon and glass fibers, a stable high frictional factor can be achieved when it is employed as a frictional material for a torque variation absorbing device which performs a rolling motion. Since the abrasion resistance against the rolling motion is quite excellent, the abrasion quantity is quite low thereby the operational characteristic and the durability of the device can be improved.

Title: Schmitt input circuit
Inventor: KEIDA HISAYA
IPC: H03K5/13
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To allow a circuit to have provision for different power supply voltages while setting a proper logic threshold voltage and reducing the required circuit scale. SOLUTION: In the case of using the circuit for a high power supply voltage, a point CS goes to logical L, and in the case of using the circuit for a low power supply voltage, the point CS goes to logical H. For a power supply voltage of 5V, a logic threshold level when all of TP3, TP4, TN3, TN4 are nonconductive is used for a rising logic threshold level and a logic threshold level when the TP3, TP4 are conductive is used for a trailing logic threshold level, then the logic threshold level going to be likely to be increased toward power supply voltage increase is suppressed.  In the case of using a low power supply voltage, a logic threshold level when the TN3, TN4 are conductive is used for a rising logic threshold level and a logic threshold level when the TP3, TP4, TN3, TN4 are nonconductive is used for a trailing logic threshold level, then the logic threshold level going to be likely to be decreased toward power supply voltage decrease is suppressed.
