Title: Steelmaking material
Inventor: NIIOKA KOUJI
IPC: C22B1/00
Filed: 1988-05-30
Abstract: PURPOSE:To produce the title efficient steelmaking material by recovering coarse scales generated in converter blowing, adjusting the water content, adding a caking agent or further a carbonaceous material, powdery limestone, and collected dust, and molding the material. CONSTITUTION:The dust generated in the steelmaking refining by a converter is recovered by a wet dust collector, and classified into coarse scales and fine scales to recover. Since the coarse scale consists essentially of metallic iron, a caking agent such as corn starch or lignosulfonic acid is added, the mixture is molded and then dried, or the mixture is dried to the extent that the mixture can be molded and solidified, then added with the caking agent, and molded. In this case, 50-20% powdery carbonaceous material, 3-50% powdery limestone, or further 3-10% collected dust are simultaneously added, and the obtained mixture is molded. When the molded product is charged in molten steel as a steelmaking material, the oxidation loss of molten iron is eliminated by the presence of the carbonaceous material, the melting time to obtain molten steel is reduced by the decomposition and disintegration of limestone, the compressive strength of the molded product is improved by the addition of dust, and the handling property is ameliorated.

Title: Switching circuit
Inventor: NORO YASUHIRO
IPC: H01H9/54
Filed: 1992-04-27
Abstract: PURPOSE:To compensate the voltage lowering of a switch by constituting a system in such a way that a main switching circuit is serially connected with a compensating circuit and the feed-back point of the compensating circuit is changed-over by means of first and second change-over switching circuits. CONSTITUTION:When a closure command is given to the switching circuit from an open/close control terminal C, photocouplers 52 and 53 become an on-state so that the voltages of power sources 58 and 59 are impressed on between the gate sources of MOSFET 11, 12, 41 and 42 and the main switching circuit 1 and the change-over switching circuit 4 become a closure state. In the meantime, the photocoupler 51 becomes an off-state by an inverting circuit 60. Therefore, the voltage of the power source 57 is not impressed on the gate sources of MOSFET 31 and 32 and the change- over switching circuit 3 becomes an open state. Since the feed-back terminal E of the compensating circuit 2, that is, the inversion input terminal of an operation amplifier 20, is connected to a terminal B with the change-over switching circuit 4, the operation amplifier 20 equally keeps potential between the terminals A and B together with MOSFET 21, 22, the power sources 27, 28 and diodes 26, 29. As a result, voltage lowering does not occur between the terminals A and B even if a current is permitted to flow between the terminals.

IPC: G11B20/06
Filed: 1988-05-31
Abstract: PURPOSE:To stabilize an oscillation action and to evade the mixing of the frequency modulating signal of an input signal by flying back the output of a voltage comparing circuit with a high gain to the input edge. CONSTITUTION:Based on an input signal Sv, first and second triangular wave signals SVA and SVB to rise alternately are formed and the first and second triangular wave signals SVA and SVB are respectively supplied to first and second input edges (a) and (b). Flyback signals SF1 and SF2 are obtained from first and second output signals SOUT1 and SOUT2 outputted from a voltage comparing circuit 3. The flyback signals SF1 and SF2 fly back to second and first input edges of the phase reverse to the output signals SOUT1 and SOUT2 respectively, and the triangular wave signals SVB and SVA are respectively raised by the level of the flyback signals SF1 and SF2. Thus, the oscillation action of the voltage comparing circuit 3 is stabilized and a frequency modulating action can be stably performed.

Title: Automatic document carrying equipment
Inventor: TSUNODA ARIHIRO
IPC: G03B27/62
Filed: 1988-05-31
Abstract: PURPOSE:To prevent a document once discharged from being carried again below a document carrying roller so as to prevent jamming, etc., by providing a discharge roller which is driven only in a direction to discharge the document and a floating roller which rotates in contact with the discharge roller. CONSTITUTION:By separately driving a document carrying roller 30 and a discharge roller 45 in rotation, documents are discharged by both rollers. At this juncture, the discharge roller 45 is supported by its shaft via a one-way- clutch 461, and at the same time, installed in a state in which it is in contact with a floating roller 35. For this reason, driving force is not transmitted by the one-way-clutch 461, to the discharge roller 45 while the document carrying roller 30 is rotating in the normal direction where the document is carried toward a plate on which the document is placed and the discharge roller 45 and the floating roller 35 are kept in a halt states. Thus, reverse carrying of the discharged document can be prevented from being taken in by the discharged roller 45.

Filed: 1982-08-03
Abstract: PURPOSE:To make an operator unnecessary, also to shorten a recovery time, and to improve the rate of operation, by initializing automatically a central processing unit, at the time of a fault, and executing its recovery processing in case of a temporary fault having no reproducibility. CONSTITUTION:When a central processing unit (CPU) 1 becomes faulty and stop its processing operation, a fault signal is sent to a microprocessor 21 through a line 11. As a result, the processor 21 reads out an initializing instruction stored in a control storage 22, sends it to a decoder 24, and supplies a signal of logical ''1'' to an FF 25. The FF 25 sends an initializing signal of logical ''1'' of fixed length to the CPU 1 through a line 13. By this signal, the CPU 1 sets automatically contents of each register, the FF, etc. to an initial value determined in advance. Subsequently, the CPU 1 shifts to an operation of software, the fault recovery processing is executed, and the CPU can be reset to a state before the fault.
