Abstract: A carrier for microcircuit LSI chips (180) includes stacks (11) of parallel ceramic sheets (14) carrying thin conductive capacitor plates (20) laminated in a ceramic structure, in which the capacitor plates serve as power distribution conductors. Groups of plates provide electrical connection (19,21) beteeen power supply strips (16) and conductor straps (95, 98) which are connected to solder bonds (181) for the chips. This provides capacitance to smooth the power supply to high switching speed VSL1 chips. Stacks (11) of laminated ceramic capacitors serving as power planes are inserted into slots in laminated ceramic sheets. Signal vias (42) are provided about the periphery of the power planes. A highly parallel distribution of current is provided by means of horizontal power conducting straps which reduce voltage fluctuations, electrical resistance, and current per via.

Abstract: 1362105 Character recognition systems; magnetic heads INTERNATIONAL BUSINESS MACHINES CORP 1 Dec 1972 [27 Dec 1971] 55661/72 Headings G4R and G5R Data, such as legible characters, in the form of patterns of magnetic material on a non-magnetic support, is sensed by a magneto-resistive member 14. The support, such as cheque 2, is moved under the poles of a magnet 8 which provides a field My in the region of the characters under the magnet. The magnetic ink is subjected to the horizontal field component Bp. The vertical component Bh biases the magnetoresistive member 14 to operate at the most sensitive part of its characteristic. The easy axis of magnetization of member 14 is parallel to the plane of the cheque 2 so the resistance of member 14 changes according to the flux from the characters as they pass beneath it. The resistance changes are used to provide a signal to recognition circuitry.

Abstract: A method and means is described for writing data on a recording medium, such as a disk or tape, containing servo samples in such manner that the number of servo samples is increased with a minimal increase in overhead (non-data) regions. The tracks on the medium are divided into a plurality of maxi sections, each of which contains all fields with servo and associated overhead information and also a data field. At least one micro servo section containing only a portion of said information is located within each data field. As each micro servo section passes by an associated recording head, writing and reading of data is temporarily interrupted, but resumed when the micro servo section moves beyond the head, in such manner as to require minimal resynchronisation of said data during reading. Using a phase continuous clock, data is written in both portions of a data field to either side of each micro servo section in one pass of the disk or tape relative to the head. The micro servo sections contain no timing reference address mark and require no data encoder/decoder flush or synchronisation byte to resume reading in the portion of the data field following each micro servo section.
