Abstract: Compositions having the formula A 1±x M 2±x Cu₃O y , wherein A is Y, or a combination of Y La, Lu, Sc or Yb; M is Ba, or a combination of Ba, Sr or Ca and y is sufficient to satisfy the valence demands, have been found to be bulk electrical superconductors at a temperature above 77K. The compositions are single phase perovskite-like crystalline structures. They are made by a process involving intimately mixing the metal oxides or their precursors in the proper molar ratios, heating the mixture in the presence of oxygen to a temperature between about 800°C and about 1100°C and slowly cooling the mixture to room tempera­ture in the presence of oxygen over a period of at least four hours.

Abstract: In a magnetic head assembly comprising a main magnetic pole (15), a coil (17) magnetically coupled to the main magnetic pole and an auxiliary pole (13) disposed alongside the main magnetic pole for forming a return path for magnetic flux, the permeability of the auxiliary magnetic pole increases progressively with distance from its side (13b) adjacent to the main magnetic pole up to its centre and then decreases progressively with distance from its centre to its side (13c) remote from the main magnetic pole. The auxiliary magnetic pole may consist of a lamination of thin films. 
     The permeability profile of the auxiliary magnetic pole enables its end face to be disposed at the same level as the end face of the main magnetic pole, without giving rise to increased edge pulse noise.

Abstract: Monitoring apparatus is provided to allow out-­of-sequence fetching of operands while preserving the appearance of in-sequence fetching to the processor of a computer. The key elements include a stack (119) of N entries holding the addresses of the last M, where M is less than or equal to N, out-of-sequence fetches. A comparator (103) is provided for comparing addresses in the stack with a test address. This test address is supplied via an OR gate (107) as either store addresses or cross-invalidate addresses, the latter being for a multiprocessor system. The addresses in the stack that compare with the test address are set as invalid. In addition, all addresses in the stack are set as invalid on the occurrence of a cache miss or serializing instruction. Finally, a select and check entry function (113) associates an address in the stack with the instruction it represents and deletes the address from the stack when the instruction is handled in its proper sequence.

Abstract: There is provided a digitally controlled first order hold circuit and waveform synthesizer for digitally controlling the representation of a function over an approximation interval. In accordance with the operation of the invention, the first order hold circuit and wave­form generator receives a digital data input signal which contains initial condition data, up/down data, and slope data for the approximation interval. The initial condition data is loaded into an up/down counter (32) which is incremented using counting data at a rate de­pending on the value of the slope data and in a direction depending on the value of the up/down data. In order to minimize delays arising from data acquisition, two frequency synthesizer circuits (22, 24) are provided such that one frequency synthesizer (22) provides counting data while the other frequency synthesizer (24) receives slope data. During alternating intervals, the other frequency syn­thesizer circuit (24) provides counting data while the other circuit (22) receives slope data. In addition, long length data input signals covering a plurality of approximation intervals are provided to reduce the demands on a main system central processing unit.

Abstract: An electromagnetic relay includes a coil (21) wound around a core both of whose ends (23a,23b) project therefrom. A yoke extends parallel thereto, and each of its ends is formed with two pole pieces (27) which extend towards and lie one of each side of an end of the core with a certain gap being defined therebetween. A connecting member extends parallel to the core and the yoke and is mounted so as to be movable transversely, and means (33-44) are provided for establishing and breaking some electrical connection according to such transverse movement. There are provided two armature pieces (29), one for each end of the core and both fixed to the connecting member. Each armature piece includes a permanent magnet plate (32) and two plates of magnetic material (31) fixed to it so as generally to form a C shape with one of the magnetic material plates being magnetized to be a north pole and the other a south pole. Each of the two plates of magnetic material is inserted on one side of an end of the core between it and the opposing one of the pole pieces of the yoke, into the gap therebetween. The directions of magnetization of the armature pieces are oppositely oriented. Thereby, when the relay switches over, it does so without generating any off center jerking, and thus its mounting to a base is improved. Also the quality of the magnetic circuit, and the manufacturability of the relay, are improved.

Abstract: A method for sealing holes, involves fitting an essentially bushing- and/or tube-shaped plug into a hole and then the wall of the plug is expanded radially along at least one axial segment. In this method, the plug is positively anchored axially in the hole. By this method of producing an axially positive anchoring of the plug in the hole, not only is a tight fit of the plug in the hole achieved, but a mechanical movement of the plug relative to the hole is reliably prevented. A hole arrangement is tightly sealed with an essentially bushing- or tube-shaped plug in the hole having a radially spread axial part fitting tightly in the hole. Between the hole and the plug a locking arrangement with axially positive effect is provided. In a hole arrangement of this kind, not only is tightness ensured, but also piston-like displacement of the plug in the hole is prevented. The hole arrangement can preferably be so designed that the sealing and locking parts are provided axially at different points.
