Patent CA-2009765-A1 (CA)
Inventor: BAKER ERNEST D
IPC: G06F11/20
Filed: 1990-02-07
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 directly and through the S/88 bus. Each S/370 processor is allocated from 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 access the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O 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 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.

Title: Quasi-achromatic optical isolators and circulators
Inventor: BUHRER CARL F
IPC: G02F1/09
Filed: 1990-03-09
Abstract: QUASI-ACHROMATIC OPTICAL ISOLATORS AND CIRCULATORS          ABSTRACT    A quasi-achromatic configuration of two Faraday elements and five birefringent plates which when suitably oriented between two linearly polarizing elements would constitute an optical isolator or circulator.  The nominal Faraday rotations of the two elements are 45° and 90° at a center design wavelength about which the devices are to operate.  Changes in these rotations due to either wavelength or temperature variations compensate one another because of their coupling by the birefringent plates.  In this way a higher degree of isolation is obtained over a wider optical bandwidth than would be possible in a device using a single 45° Faraday element. A group of three plates is used between the two Faraday elements and two more follow them to give the required polarization transformations which must themselves be quasi-achromatic over the desired wavelength range.

Abstract: ABSTRACT OF THE DISCLOSURE          An error correction control apparatus includes a transfer control part for transferring information on a plurality of tracks in a parallel form, and a plurality of error track pointer circuits provided for each of the plurality of tracks.  Each of the plurality of error track pointer circuits indicates one of the plurality of tracks having an error to be corrected. Error detectors, which are provided for each of the plurality of tracks, detect different types of errors included in the information on a corresponding one of the plurality of tracks and set the plurality of error track pointer circuits to an initial state.  An error correction circuit corrects the errors indicated by the plurality of error track pointer circuits on the basis of error correction information included in the information on the plurality of tracks.  A reset part selectively resets the plurality of error track pointer circuits on the basis of reset information included in the information on the plurality of tracks.

IPC: H04Q11/04
Filed: 1990-10-03
Abstract: Integrated Services Digital Network (ISDN) terminal equipments (TEs) are remotely powered from a central source via line interface circuits.  One function of the line  interface circuit is that of conducting energizing direct current for the associated telecommunications terminal equipment while providing effective over current protection in spite of widely variable load current requirements which occasionally may mimic a faulty over current condition.  The line interface circuit includes first and second power terminals for connection to a source of power, first and second line terminals for supplying said energizing direct current, and a current control means, being connected between a one of the first and second power terminals and a respective one of the first and second line terminals, for temporarily switching OFF an inrush current in excess of a dynamic limit, and permanently switching OFF a load current in excess of a static limit until a virtual open circuit condition occurs across the first and second line terminals.

Title: Positive acting photoresist
Inventor: WINKLE MARK R
IPC: G03F7/004
Filed: 1990-10-15
Abstract: ABSTRACT OF THE DISCLOSURE A positive-acting photoresist composition which produces crosslinked images and processes for using the photoresist composition are disclosed. The photoresist composition is prepared from a mixture containing a film forming, polymer-containing, acid hardening resin system, an acid or acid generating material (preferably in the form of a thermal acid generator) for crosslinking the acid hardening resin system, and a photobase generating compound. The photoresist composition is applied as a film onto a substrate surface and selectively imagewise exposed through a photomask to actinic radiation. The actinic radiation causes the photobase generator to produce a base in the imagewise exposed portions of the photoresist film. The photochemically generated base neutralizes the add in the imagewise exposed areas of the photoresist film. The non-imagewise exposed portions of the photoresist film, not containing the photochemically generated base, are crosslinked by the catalytic action of the acid upon heating the film, and the imagewise exposed portions of the photoresist film are removed from the substrate by the action of a developer solution leaving a crosslinked positive image on the substrate. In an alternate embodiment the photoresist composition may be applied to conductive substrate surfaces by electrodeposition.

Abstract: This invention relates to a composition arid method for improving the storage stability of acid treated polymer modified asphalts. More specifically, the storage stability of an asphalt which contains greater than 1.0 wt.% polymer can be improved by adding a branched, rather than a non branched, polymer to an asphalt which has previously been reacted with an inorganic acid. The storage stable acid treated branched polymer modified asphalt thus produced is particularly well suited for use as a binder in paving materials and as a coating or saturant for roofing shingles.
