IPC: H01L23/522
Filed: 1970-09-09
Abstract: 1312464 Semi-conductor devices MOTOROLA Inc 9 Sept 1970 [25 Sept 1969] 43185/70 Heading H1K Problems associated with the reaction between aluminium contacts or tracks and silica passivation on semi-conductor devices are avoided by preventing such reaction. An alumina layer between the materials is used for this purpose. The structure of Fig. 1d has a silicon substrate with silica passivation 12 over which runs on aluminium track 18 which is isolated from the silica (both underneath and at edge 24) by alumina layers 20, 22. The underlying alumina layer 20 may be formed by direct evaporative deposition or during the initial stage of evaporative deposition of the aluminium 18, the aluminium being deposited at relatively low temperature and in an atmosphere of relatively high pressure so that alumina is formed by reaction between aluminium vapour and residual water vapour in the system. Fig. 4f, shows the contact region of an emitter electrode 86 in the formation of which an overall deposit of alumina 80 has been provided over the apertured silica passivation 76, a contact aperture has been etched in the alumina, and an aluminium film has been deposited overall and etched to the desired portion 86 with similar etching of the alumina which however is left as a complete film to provide a barrier against interaction at this edge of the electrode. Variants of these structures use different combinations of the same features.

Filed: 1974-10-09
Abstract: 1452865 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 9 Oct 1974 [21 Nov 1973] 43665/74 Heading G4A Interactive terminal jobs and batch jobs are swapped between main and auxiliary storage in dependence on measured and estimated rates of usage of system resources by the jobs and in dependence on performance objectives specified for the jobs. When a new user logs on or a new batch job is selected, or, alternatively at regular intervals, a work load manager is invoked to process two queues of user control blocks so as to enable the performance of the system to be optimized. The user control blocks corresponding to jobs which are in main storage form an IN queue, and the first function of the work load manager is to access, 31, Fig. 2, the user control block at the head of the IN queue via a pointer 17, Fig. 1. From the accessed user CB a performance group number which has been assigned to that particular user is used to index an installation performance specification table IPS. The data stored in this table for each performance group includes constants A-C used in calculating the accumulated number of service units for each job and, for each of a number of periods which may be related to the amount of time elapsed or the number of service units accumulated since processing of the job began, a performance objective in the form of a table of service rates and corresponding normalized load levels. The number of service units accumulated by a job may be equal to A times CPU time + B times I/O count + C times a measure of main storage occupancy, the CPU and I/O count being stored in an address space control block corresponding to that user, and the main storage occupancy measure being a function of page count and CPU time. The service rate is calculated as the quotient of the number of service units accumulated divided by a time interval which is equal to the difference between the CPU time in the AS CB and the old CPU time in the user CB. From this calculated service rate the corresponding normalized load level is determined from the table in IPS and the same procedure is carried out for the next user CB in the queue. Finally the user CBs are reordered according to the new calculated normalized load levels. A similar reordering of the user CBs in the OUT queue is performed except that the queue is in reverse order of normalized level and anticipated service data are used since the jobs are not actually in course of execution. Should the normalized level at the head of the OUT queue be greater than the normalized level at the head of the IN queue then a swap between the heads of the two queues takes place. By providing different performance objectives different users can be handled in different ways and the different service rates specified in each performance objective permit the same user to be treated differently depending on the system work load.

Abstract: 1518725 Muting during tuning LICENTIA PATENT VERWALTUNGS GmbH 21 Oct 1976 [21 Oct 1975] 43744/76 Heading H3Q In an arrangement for reducing interference resulting from switching functions of a radio receiver a gradual increase in the damping of the received signal is initiated in response to a switching action initiation prior to the switching action being accomplished and then the damping is gradually reduced after the switching action has been accomplished. A start signal A for the frequency change process causes a clock pulse generator in control 4 to change the integration constant of an integrator 5 so as to control PIN diodes of a damping element in the above manner. The time curve of the response to voltage factor of the damping element 7 is produced which approaches the Gaussian distribution function or causes the smallest interference at IF filter 8. When the maximum damping is reached a pulse is emitted from the control 4 to digitally switch the frequency of a variable frequency oscillator 2 via a buffer store 3.

The edges of the member are formed with rounded protrusions 3 separated by recesses 4 to facilitate keying during the subsequent application of plastic-impregnated bandages. The tape has a lower concave face provided with a layer of adhesive material (5) Fig. 3, (not shown), covered by a protective sheet (6) of paper whilst the top face (7) of the said tape is convex and is provided with a plurality of projections 8, 9. The tape 1 has a rib 10 which extends longitudinally down the middle of the top face and a longitudinal channel 11 extending almost through the said rib and forming a line of weakness. The wire 2 is in the form of a helix and is embedded in the rib 10 such that parts of the wire extend across the channel 11. The ends of the cutting wire extend from the ends of the tape and are each secured to tabs 12. In order to remove the hardened cast, a reel (51) Fig. 15, (not shown), connected to one of the said tabs, is rotated to wind up and tension the cutting wire thus causing the wire to produce a longitudinal cut (52) in the cast (50). The reel (51) includes two end flanges (53) connected by a spindle (54) which has a slot in which a tab can be located. In an alternative embodiment, the tape is formed in two portions (15), (16) Fig. 6, (not shown), completely separated by a longitudinally extending slit (17) and held together by the wire, which may alternatively be a serpentine configuration, Fig. 8, (not shown). In a further embodiment, the strip-like element is formed from a serpentine-arranged cutting wire, Fig. 10, (not shown), with the crests (25) of the wire embedded in generally triangular flat, plastics body portions (26). Alternatively, the strip-like element comprises a preformed corrugated tape (30) Fig. 11, (not shown), the corrugations extending transversely to the said tape, the cutting wire being in the form of a rectangular helix encapsulated in the tape.
