Abstract: A data reproduction circuit for converting a read analog signal into digital data corresponding to recording data, has a second order differential circuit (102) for emitting a second order differentiated signal (H) of the read analog signal read from a data recording medium, an inverter (207) for generating a comparative voltage that is switched between a plurality of levels, and a comparator (205) for comparing the second order differentiated signal (H) and the comparative voltage (M) to release digital data (Ca). This permits to cancel a DC component of the read analog signal and to adopt a 2,7NRZI method for recording and reproduction enabling to achieve a high recording density. The circuit further comprises a peak detecting circuit (103) for detecting and converting a peak of the read analog signal into digital data, and that has a first order differential circuit (101) for emitting a first order differentiated signal (G) of the read analog signal (B), a three-state inverter (210/211) generating a second comparative voltage (N₁,N₂) that is switched between a plurality of levels, and a comparator (208) for comparing the first order differentiated signal (G) and the second comparative voltage to release digital data (Cb). The circuit may thus be adopted for both RZ and NRZI methods.

Abstract: A computer software compiler system and method for distributing a machine independent computer program, created on a native computer platform, to heterogeneous target computer platforms. The system comprises installer components which exist on heterogeneous target computer platforms. The installers receive a compiler intermediate representation of the machine independent computer program. The compiler intermediate representation is architecture neutral and represents an architecture neutral distribution format. The installers translate the compiler intermediate representation to object code representations according to a compiler intermediate language. The installers operate in a machine dependent manner such that the object code representations are architecture dependent, or machine dependent, on the target computer platforms.

Abstract: A method (10-13) is disclosed for displaying characters using a computer system (1). A colour table (4) is pre-stored with 16 colours, eight of which are grey scale colours between and including black and white. Thus, if text or any other pre-set type of character is to be displayed the processor (2) works with the eigth grey scaled colours for anti-aliasing. for other characters, the other eight colours may optionally be used. Thus, efficient anti-aliasing is achieved without use of more processing power than conventionally required for processors using using a "VGA" colour table. Indeed, less is required because when dispaying text a three-bit code is sufficient instead of 4-bit.

In this apparatus, the ratio or the difference between at least two predictive error data obtained with a plurality of frequency characteristics is calculated and then is compared with a predetermined reference value. And the frequency characteristic in the corrector means is controlled in conformity with the numerical relation between the calculated value and the reference value. Therefore two or more frequency characteristics in the corrector means are selectively rendered conformable with one frequency characteristic in the predictive error generator means, hence achieving an enhanced effect of further improving the signal-to-noise ratio.

Abstract: The invention relates to a process for the purification of circulated liquids and effluents, in particular cooling and lubricating media from working processes, in which the liquid to be purified enriched with solid particles is passed into a working vessel and is treated there with a flocculating agent which binds the particles and allows them to sink to the bottom, converted to flocks, from where the compressed flocks are withdrawn and filtered off from the circulated liquid outside the working vessel. In order to create a process and device for carrying out the process for the purification of circulated liquids and effluents, which enables the continuous purification to achieve a uniformly low pollutant concentration, it is proposed that the circulated liquid is fed, with simultaneous continuous feed of the flocculating agent, to the working vessel via a mixing section in which flocculation is initiated with thorough mixing of circulated liquid and flocculating agent, which flocculation continues in the working vessel, the flocks containing the bound particles sinking to the bottom at a low rate of flow through the working vessel, and the purified liquid being withdrawn at the top of the working vessel at a side remote from the feed of the liquid to be purified, while the thin sludge composed of the flocks enriched with particles and the circulated liquid is continuously withdrawn to the bottom of the working vessel and is fed to a filter to separate the circulated liquid to be recycled. <IMAGE>

Abstract: In a byte destuffing circuit, a received data signal in a byte interleaved multiple frame structure is stored into a buffer memory, and a clock sequence is recovered. The recovered line clock is applied to a write address generator for storing the data on a per byte basis into a buffer memory. In response to a destuffing control signal, the write address generator suspends the generation of a write address if positive byte stuffing is effected at the transmit end, and destuffing is effected on the recovered clock sequence on a bit-by-bit basis during successive eight frames. The destuffed clock sequence is applied to a phase comparator for comparison with a local clock sequence generated by a VCO which is controlled by the phase comparator in a phase-locked loop. The local clock sequence is used to drive a read address generator for reading data from the buffer memory on a per byte basis.

Abstract: A T-gate structure (28a) is fabricated on a microelectronic device substrate (10) using a trilevel resist system in combination with a two-step reactive ion etching (RIE) technique utilizing an oxygen plasma. The trilevel resist consists of a planarizing resist layer (12), masking layer (14) and imaging resist layer (16), which are formed on the surface (10a) of the substrate (10). A focused ion beam (18) is then used to expose the uppermost imaging layer (16) with an image having a width equal to the desired gate length of the T-gate structure (28a). The imaged area is developed and etched to form an opening (14a,16a) of the same width through the imaging layer (16) and also through the masking layer (14). In the first oxygen RIE step, the planarizing resist layer (12) is etched isotropically through the opening (14a,16a), partially down to the substrate surface (10a) to form a cavity (12a) having a width which is larger than the width of the opening (14a,16a). The second oxygen RIE step is used to etch the planarizing resist layer (12) through the opening (14a,16a) completely down to the substrate surface (10a) to form a notch (12b) underneath the cavity (12a) having a width substantially equal to the width of the opening (14a,16a) and thereby the gate length of the T-gate structure (28a). The imaging layer (16) and masking layer (14) are removed, and metal (28) is evaporated onto the substrate (10) to fill the cavity (12a) and notch (12b) and thereby form the T-gate structure (28a). The first resist layer (12) and overlying metal (28) are lifted off, leaving the T-gate structure (28a) on the surface (10a) of the substrate (10).
