Abstract: A speed enhancement technique for CMOS circuits is disclosed. In the series of logic stages, nodes in the signal path of a pulse are set by preceding logic stages, then reset by feedback from a subsequent logic stage. This eliminates the capacitive burden of resetting any given node from the input signal to allow substantially all of the input signal to be employed in setting the nodes to an active state rather than wasting half the signal in turning off the reset path. The technique is illustrated as applied to RAM circuits.

Further, a superconductor structure is formed which includes a plurality of superconductor layers and has a superconducting transition temperature or super­conducting critical current higher than that of each superconductor layer, and a superconducting device including this superconducting structure can operate at a relatively high temperature. Furthermore, a superconducting circuit device is formed which can emit a coherent electromagnetic wave having a wavelength of the order of 10 µm on the basis of the difference in energy gap between adjacent superconductor layers (22, 23).

Abstract: An improved chromatographic device and method for quantitating the activity of an enzyme utilizes a bibulous test strip as the stationary phase, an aqueous solution as the mobile phase, and a chromophore as the indicator. The enzyme activity is quantitated by transforming a substantially depletable amount of a chromogenic substrate from soluble chromogen to insoluble chromophore as the mobile phase advances, whereupon the insoluble chromophore becomes immobilized on the test strip to produce a column of color. The length and/or the intensity of the column of color are related to the activity of the enzyme. The present invention is useful for the direct determination of enzyme-analytes and for the indirect determination of analytes which can be coupled to an enzyme.

Abstract: A line thermal printer for making a print on a paper having a bar code indicating such as a paper size. As a predetermined position of a line thermal head is heated, with the paper sandwiched between the thermal head and a platen, a desired printing action is progressively performed. For reading the bar code of the paper before printing, a bar code reader mechanism is provided which includes a sensor carrier unit for reading the bar code by scanning, and a guide member for supporting the paper on the opposite side. A thermal line printer mechanism is movable between a printing position in which the head and platen are close to each other and a non-printing position in which these two parts are remote from each other. Also the bar code reader mechanism is movable between a reading position in which the sensor carrier unit and the guide member are close to each other with the paper sandwiched therebetween and a non-reading position in which these two parts are remote from each other. Accordingly, feeding of the paper, reading of the bar code defining printing conditions and printing can be performed continuously and automatically.

Abstract: An ECL to TTL translator (10) converts a signal from ECL logic levels to TTL compatible logic levels without introducing current spikes in the output signal during logic transitions. The ECL input signal (12, 14) is transformed into first and second differentially related currents which develop first and second voltages at two nodes (28, 36) for biasing first (30, 44, 46) and second (34, 48, 50) switching circuits which in turn generate first and second complementary control signals. The sum total of the differentially related currents are limited to a predetermined magnitude blocking simultaneously assertion of the control signals. An output stage (56, 58, 60, 62, 64, 66) includes upper (56, 58) and lower (60) transistors each responsive to the first and second control signal respectively for developing a TTL high and TTL low output signal. The first and second switching circuits inhibit simultaneous conduction of the upper and lower transistors of the output stage preventing undesirable current spikes in the output signal thereof.

Abstract: The functions of two virtual operating systems (e.g. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors dirertly and through the S/88 bus. Each S/370 processor is allocated form 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors across the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/0 data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs to execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.

Abstract: A photosensitive member suitable for multi-­color image formation is obtained by forming a plurality of photosensitive layers laminated on a substrate. Each photosensitive layer comprises a matrix phase and particles dispersed therein. The matrix phase contains a photosensitive silver salt, an organic silver salt and a reducing agent which react with each other on exposure and heating to form a light-absorbing organic compound. The particles contain a heat-diffusive colorant, a polymerizable polymer precursor and a photopolymerization initiator. The light-absorbing organic compound in a photosensitive layer being capable of absorbing a wavelength of light to which the photopolymerization initiator in the photosensitive layer is sensitive. Because the heat-diffusive colorant, the polymerizer and the initiator are contained in the particles, the diffusion of the heat-diffusive colorant can be effectively controlled to prevent color fog.

Abstract: A magneto-optical (M-O) storage system includes optical means for detecting edge transitions between magneto-optical domains. The beam returning from the storage medium is analyzed both spatially and in polarization. When a transition is centered under the read laser beam, the spatial reversal in the sign of the amplitude of the signal polarization due to the spatially nonuniform Kerr rotation is compensated by a reversal due to spatially nonuniform (split) detectors or a matched optical filter. The optical powers on the two sides of each split detectors or on two independent detectors sensitive to orthogonal polarizations become unequal thereby producing an electrical signal signal which comprises spaced peaks in opposite directions at the leading and trailing edges of the M-O domain or mark.
