Abstract: In order to write a servo pattern on each of a plurality of record disks (18, 62) in a data storage device, first and second base patterns (51, 52) are first written on one (18) of the disks. The first base pattern (51) comprises a series of portions spaced along one radius of the disk, an individual one of the portions being situated at each track centre. The second base pattern (52) comprises a set of pattern portions, an individual one of the portions lying substantially continuously over each radius of a plurality of radii defining the positions of servo sectors. A sector servo pattern is then written on each of the record surfaces of the disks (18, 62) under control provided by detection of the base patterns (51, 52) on the one disk (18). The latter operation of writing the sector servo patterns on the disks need not be performed in a clean room.

Abstract: In a phase perturbation compensation system for use in a data modem receiver, the signal from an equalizer (114) is fed to a phase and amplitude correction circuit (150) which is connected to a decision circuit (122) providing a data output signal (124) and a phase error output signal (120d) which is applied to a phase jitter compensation deter­mination circuit (156). The phase jitter compensation determination circuit (156) includes a tapped delay line (269) the output taps of which are applied to multipliers (272-1 to 272-16) fed with adaptive weighting coeffi­cients to provide values which are summed to provide a phase error prediction signal. The weighting coeffi­cients are generated in integrator circuits (274-1 to 274-16) which include respective delays (288-1 to 288-­16). The values generated in the delays (288-1 to 288-­16) during an initial training sequence and stored in a storage device (130) are retrieved for use in subsequent training segments, whereby fast phase jitter adaptation is achieved and hence short training sequences can be utilized.

Abstract: Addresses corresponding to magnetic disk sectors are encoded using an error correction code (ECC), such that addresses which are in a neighborhood, that is, addresses which are mathematically or numerically close, are mapped to addresses which differ in at least D-1 bits where the ECC is a distance D code. An original n-bit sector address is separated into two segments. One segment is a "k"-bit neighborhood address segment containing the k lower order address bits identifying the location of the selected sector within a neighborhood. The second segment is an "n-k" bit higher order address segment identifying the neighborhood containing the selected sector. The k-bit neighborhood address segment is then encoded with an (n,k) distance D linear code to form an n-bit preliminary code word containing n-k redundancy (ECC) bits appended, as the most significant bits, to the k neighborhood address bits. The (n-k)-bit higher order address segment is encoded by representing the segment in Gray code. The (n-k)-bit Gray coded segment is added modulo 2 to the n-k redundancy (ECC) bits of the preliminary code word. The resulting n-bit address code word is recorded on the disk as the sector address. When a particular sector is to be accessed, the address is first encoded in the manner set forth above, and the read/write head is moved to the logical neighborhood containing the sector. The encoded address is then compared to the addresses written in the various sectors in the neighborhood. When a match within (D-2)/2 bits is found, the sector is identified as the correct sector.

Abstract: A computer assisted language translating machine which comprises a morpheme analyzer for separating a source language sentence into morphemes with the use of diction­aries; a syntax analyzer for analyzing the syntax of a string of the morphemes with the use of a dictionary and grammatical rules; a converter for converting a syntactic structure of the input sentence into a syntactic structure of the target language; and a sentence generator for gene­rating a translated sentence according to the syntactic structure of the target language converted by the converter. A code input unit is provided for inputting a dictionary specifying code to one of words which requires the use of a particular one of the dictionaries, utilized by the morpheme analyzer for dictionary referencing, when being translated into a target language counterpart. A discriminator deter­mines whether or not the dictionary specifying code has been affixed by the code input means to such one of the words. A dictionary referencing unit is operable, when the discrimi­nator determines that the dictionary specifying code has been affixed to such one of the words, to make reference to such particular one of the dictionaries and also operable, when the discriminator determines that the dictionary specifying code has not been affixed to such one of the words, to make reference to all of the dictionaries according to a predetermined system dictionary referencing sequence.

Abstract: A method of forming in a semiconductor material a region having a different chemical composition or a different concentration than a chemical composition or concentration of material surrounding the region. The method includes an initial step of providing a substantially single crystalline body of material, such as an epitaxial layer 10 of HgCdTe. Another step forms a cap layer 12 over a surface of the body, the layer having a thickness T. The cap layer 12 is comprised of a layer of polycrystalline material, such as CdTe, or is comprised of a layer of an organic material, an amorphous dielectric or a single-crystalline layer. A further step implants a selected chemical species through an upper surface of the cap, the species being implanted to a depth such that substantially no implant damage is sustained by the underlying body. In p-n junction formation the species is selected to form a region having an opposite type of electrical conductivity than the conductivity of the layer 10. A further step diffuses during a thermal anneal the implanted species from the cap layer down into the underlying layer to form a region therein having a different chemical composition or concentration than the chemical composition or concentration of the material surrounding the region. The method is also shown to be suitable for bipolar and JFET transistor fabrication in Group II-VI and Group III-V materials.
