Abstract: An information processing apparatus includes in its body at least a power supply unit, a disk type storage and a printed circuit board arranged in a predetermined order and further has a keyboard unit which can be sandwiched between the display unit and a keyboard unit supporting portion extending from the body by pivotally moving the display unit. A detector for detecting the detachment of the keyboard unit from the body may be provided to restrict the range of pivotal movement of the display unit in accordance with a detection signal of the detector. Further, the display unit may be provided with pilot light emitting portions, thereby making it possible to recognize a condition of the information processing apparatus.

Abstract: A display controller of a flat display apparatus which performs multiple color display and variable color display for display data read out of a lookup table. The lookup table comprises a parallel lookup table which has n (n.gtoreq.2) registers for storing color information and m selectors which receive n pieces of color information independently from the n registers, each select one of n pieces of color information, and deliver m pieces of color information simultaneously. The controller further comprises a data selector which selectively delivers the output of other register in the parallel lookup table in place of the register which has been made the read access.

Abstract: For an input value, conformity grades are computed and are displayed for established membership functions. Alternatively, conformity grades and change rates thereof developed when a fuzzy reasoning system is operated are displayed. Alternatively, a change with respect to time of the input value is displayed to be superimposed onto a table representing the established rules. Alternatively, an output value resultant from a fuzzy reasoning conducted with a particular rule removed is compared with a fuzzy reasoning achieved by using all rules, thereby displaying the difference on a rule table. As above, various features in the fuzzy reasoning are extracted and are displayed so as to check adequacy of the established membership functions and rules.

Abstract: A powdery or fine granular ore containing metal oxides is melted and refined by charging the ore and a part of a reducing gas discharged from a vertical type of melting and reducing furnace into a fluidized bed type of preliminary reducing furnace to preliminary reduce the ore therein, charging the preliminary reduced ore heated at a high temperature into the above described melting and reducing furnace and melting and reducing the ore by using a carbonaceous solid reducing agent and air or oxygen rich air heated at a high temperature and discharging the molten metal and the molten slag from the melting and reducing furnace. By using the preliminary reduction step, the pretreatment of the powdery or fine granular ore containing metal oxides, such as formation into pellets, sintered ores, briquets and the like can be omitted.

Abstract: A one-dimensional image sensor comprising a solid image pick-up element takes images in sequence, and generates an image signal. Clock pulses from a frequency variable type clock pulse generator having a frequency which varies in correspondence to a control signal are supplied to a one-dimensional image sensor, thereby image signals are outputted in sequence. The image signal is amplified by an amplifier and inputted to a comparator and compared with a reference signal. A frequency variable range of the frequency variable type clock pulse generator is set higher than the cut-off frequency of the amplifier, and the binary level output by the comparator is substantially the same as the image inputted to the one-dimensional image sensor and control is effected by the variable frequency of the clock pulses.

Abstract: A method of producing amorphous mother alloy is disclosed, which comprises charging raw material, carbonaceous reducing agent and secondary material into a smelting furnace and then smelting to produce Fe-B-Si series molten metal having a B-Si composition range which lies within an area represented by the trapezoidal area abcd shown in FIG. 2 of the accompanying drawings. The amorphous mother alloy is used to produce an amorphous starting material by diluting with molten steel.

Abstract: Fe-B molten metal for producing amorphous alloys are produced in a low cost by using a vertical furnace wherein beds packed with a carbonaceous solid reducing agent are formed and two or three stages of tuyeres are provided in the lower portion of said furnace, feeding a preliminarily reduced powdery iron ore into the furnace through the upper stage of tuyeres together with hot air and feeding boron oxide or boric acid into the furnace through the lower stage of tuyeres together with hot air and, if necessary blowing hot air into the furnace through the lowest stage of tuyeres. In stead of the above described vertical furnace, a usual blast furnace provided with one or two stages of tuyeres at the lower portion of said furnace is used. In this case, sintered iron ore, pellet-formed iron ore or lump iron ore is fed from the top of the furnace and powdery boron oxide or boric acid is fed through the tuyeres.
