Title: Magnetic recording substance
Inventor: NOMURA MASAAKI
IPC: G11B5/70
Filed: 1979-10-31
Abstract: PURPOSE: To obtain a recording substance which is capable of sufficient record magnetization although the signal current to the magnetic head is small, by providing a layer of high-permeability material on the back side of the base of a magnetic recording substance.  
     CONSTITUTION: The magnetic materials such as the γ-Fe 2 O 3 , Fe 3 O 4 , Co-γ-Fe 2 O 3  and the like are diffused into the resin and then coated on the surface of the base 6 to form the magnetic recording layer 5. The transistion metals such as Fe, Ni, Co and the like plus the high-permeability material layer 7 of the alloy of above-mentioned transistion metals are adhered on the back of the base 6. The signal current is flowed to the coil of the magnetic head 9, and the signal magnetic field is applied to the layer 5 through the gap part 8. Thus this magnetic field receives the effect of the layer 7 to secure a sufficient record magnetization up to the inside of the layer 5. Then the development is carried out by the magnetic toner to obtain a copied picture having high concentration.

Abstract: PURPOSE:To prevent a short channel effect and leaking currents in the vicinity of a threshold voltage, by using a double heterojunctions, wherein a two-dimensional carrier is formed in a well-type potential. CONSTITUTION:In an FET, which is formed by using a GaAs/AlGaAs heterojunction, the thickness W of a non-doped GaAs film 40 (residual impurity level is 10<14> cm<-3> or less) is set at a specified length. Namely, the thickness W of the non-doped GaAs film 40 is set so as to satisfy the relationship of w approx.<2dpsi, where dpsi is the expanse of a two-dimensional carrier in the vertical direction of an interface. Thus, said two-dimensional carrier can be confined in a one- dimensional well type potential, which is formed by an non-doped AlGaAs buffer layer 42 and a non-doped AlGaAs spacer layer 41. As a result, in the submicron region of a gate length, especially a short channel effect and the effect of leaking currents in the vicinity of a threshold value can be prevented.

Unless there is a variation in the zero-phase current 3i0, an output of the subtracter 15 is '0'. If a sudden variation is generated in the zero-phase current 3i0, a variation portion of an output current of the CCD1 13 appears in the output of the subtracter 15 within a prescribed time.

IPC: B41M5/50
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To obtain a good absorption property of ink, water resistance, and the durability of images by forming on the base material a dye fixture layer consisting mainly of an interlayer compound and binder for fixing and holding water soluble resin by an intercalation reaction, and containing organic anion and a polyvinylalcohol resin binder. SOLUTION: The recording medium has a dye fixture layer 1 consisting mainly of an interlayer compound, an organic anion, and a binder formed on the base material 2. The interlayer compound fixes and holds a water soluble dye in ink on the dye fixture layer 1 through an intercalation reaction. For an anion exchange layer compound having a changeable anion between layers, the mineral of a stratified hydrotalcite group comprising an AlO6 octahedral sheet is suitable. Also, the interlayer compound is desirably contained relative to solid matter in the dye fixture layer 1, or since the binder contains polyvinylalcohol resin, it permits the interlayer compound to disperse sufficiently, and also render the coated film insoluble without causing the deterioration of ink absorption.

Title: Digital signal processor
Inventor: TANAKA YOSHIAKI
IPC: G06F17/10
Filed: 1987-06-04
Abstract: PURPOSE:To inform arrival at an overflow warning level by detecting the propriety for entry of output signal data on an accumulator into an area set previously. CONSTITUTION:An overload detecting circuit OL contains a presetting function for data to be compared with the cumulative value of an accumulator ACC and a comparator which compares preset data with output data given from the ACC. The output signal of the ACC is outputted to a terminal (x) when the cumulative value of the ACC enters a prescribed margin area set to a genuine overflow state of the output signal based on the result of said comparison. The comparator can perform the comparison of data on the insulated value so that positive and negative overflows are detected. The signals applied to the terminal (x) are given to a display part, for example, for visual display. The interim information of the accumulation of the ACC is not supplied to the circuit OL owing to the OFF state of a switch SW. Thus it is possible to surely know the arrival at an overflow warning level.
