Title: Signal interpolation circuit
Inventor: ISHIDA SADANOBU
IPC: H04B1/10
Filed: 1977-11-29
Abstract: PURPOSE:To enhance reliability and versatility with simple circuit constitution by converting digital signals to PAM signals and constituting a mean value interpolation circuit with analog circuits. CONSTITUTION:The digital signal corresponding to the PAM signal formed from analog signal is inputted to a D/A converter. When the signal e2 therein is repro- cuced by error, the sample error detection signal which has detected the error is inputted to a delay circuit 7 which in turn delays the sample holding signal so that the error point and the state before the wrong signal e2 is inputted to an analog switch 3b, i.e., the time when it is sample held in the analog switch 3a, coincide. The output thereof is then sent to a changeover switch 5, which sends the signal of 1/2(e1+e2) in place fo the wrong signal e2 to a buffer amplifier 2e. This signal is then held in the analog switch 3c by the next sample pulse and is outputted through a buffer amplifier 2f. Thereby, the reliability and versatility may be enhanced with the simple circuit constitution.

IPC: G11C8/16
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a multi-port storage cell in which a column interleave selection circuit element enabling writing in a storage cell through plural different writing ports, is incorporated into a SRAM. SOLUTION: A column selection switch is incorporated in each storage cell by adding additional separated switches between storage cells 410a-410c of a storage node 402a-402c and bit lines of specific writing ports in order to prevent other storage cells connected to the same word lines of the same interleaved array from being affected by writing in a cell.

Title: Stainless steel pickling tretment free of environmental pollution
Inventor: FUJII KINJIROU
IPC: C02F1/64
Filed: 1977-12-01
Abstract: PURPOSE:Hydrogen fluoride is added to wasted pickling solution in an amount of specific ratio to dissolved Fe and Cr in waste liquid, thereby to effect simple and easy separation of such metals as oxides without consuming acid ingredient. CONSTITUTION:To a wasted pickling solution for stainless steel, hydrofluoric acid is added at a room-or elevated-temperature, in a molar ratio HF/M of 3 or higher, preferably 4-5, wherein M represents metallic ion in wasted liquid, such that M=(Fe<3+> + Cr<3+>). The HF addition, by synergetic action with nitric acid existed in wasted liquid, easily precipitates Fe and Cr ions as FeF3 3H2O and CrF3 3H2O. The precipitate is separated and washed, then thermally hydrolyzed into hydrofluoric acid and metal oxides. The mother liquor containing excess hydrofluoric acid and nitric acid is circulated for use as pickling solution.

Abstract: PURPOSE:To cancel a brightness difference between a central part and a peripheral part in the picture display face of a cathode ray tube and to prevent the fatigue of eyes by applying a voltage obtained by superimposing a video signal on a parabolic voltage synchronous with the first cycle of a scanning to the cathode of a cathode ray tube. CONSTITUTION:The video signal of an input terminal 1 and the parabolic voltage from a resistance variable terminal 4c are inputted to a preamplifier 2 to amplify the video signal, superimpose the video signal to the parabolic voltage, the output is inputted to an output circuit 3 and the amplified voltage is applied to the cathode 7 of the cathode ray tube 6 in the output circuit 3. Accordingly, a cathode voltage is changed so as to gradually enlarge an amplitude to the central part at the time of horizontally scanning the peripheral part of the picture displayface of the cathode ray tube 6. Namely, the cathode voltage is controlled so as to lower the brightness in the central part of the picture display face and raise the brightness in the peripheral part. Thereby, the brightness of the picture is made constant to eliminate the problem for the fatigue of the eyes.

Abstract: PURPOSE:To improve corrosion resistance by coating respective bonding section partially while also mixing an Al corrosion inhibitor being at issue on insulating performance, such as CaCO3, SiO2, etc. on wire bonding. CONSTITUTION:A thermocompression bonding method is a system in which the tip of an Au wire 4 is heated at a high temperature, and formed to a ball shape, and the ball section 5 is pushed against an Al pad 3 and joined by a capillary 9, but pipes 10 for ejecting flexible adhesives are fixed to the side surface of the capillary 9, and the flexible adhesives 8 are ejected to the periphery of a joining section during a time when the Au wire ball section 5 is pushed. Consequently, only the Al pad being at issue on corrosion and the wire joining section can be coated with the flexible adhesives, thus acquiring the effects of temperature resistance and corrosion resistance without generating the trouble of resin cracks and wire disconnections. An Al corrosion inhibitor, such as CaCO3, SiO2, etc. can also be mixed, thus further improving corrosion resistance.

Title: Magnetic tape writing control system
Inventor: MARUYAMA TADASHI
IPC: G06F3/06
Filed: 1986-06-23
Abstract: PURPOSE:To prevent a write error from being generated by controlling the circuitry so as not to output a write data transfer enable signal to a magnetic tape controller until BOT marker trace on a start tape is passed thereby evading data write to an inhibited data write position. CONSTITUTION:The tape deformation of stick of an adhesive substance 14 on a magnetic tape 9 by a BOT marker 13 is generated by winding a tape magnetic face onto the BOT marker. Since the diameter of a winding reel 10 is nearly constant around the BOT, the BOT marker trace transferred onto the magnetic tape 9 or the adhered position of the adhesive substance exists at a location apart from the BOT marker by a length 15 equivalent to one turn of the winding reel. Then so long as the data is written from the BOT, the data transfer enable signal of the 1st data block is outputted to the magnetic tape controller after measuring the length 15. Thus, the data write position is surely evaded from a position having deformation due to BOT marker trace or the like.
