Title: Accessing storage apparatus
IPC: G11C19/08
Filed: 1974-12-27
Abstract: 1486250 Magnetic bubble devices INTERNATIONAL BUSINESS MACHINES CORP 27 Dec 1974 [2 Jan 1974] 55912/74 Heading H3B A storage apparatus consisting of a confined lattice L of mutually repulsive elements 10 (particularly magnetic bubbles) movable transverse to the lattice columns is accessed by removing elements of a column intermediate the end columns. The whole lattice is shifted left or right by the generation and annihilation of strip domains 30 in buffer zones which repel adjacent domains until the desired column is located opposite an input/output port at which the whole column may be driven out to a reading station and either retuned or the domains replaced by a generator such as 50A. The column is driven out as detailed in 55911/74 by repeated application of current to conductors 42L, 42R which enlarge domains within the column and push those ahead out of the column to a bubble puller 66A then a bubble pusher 68A. The voids left in the column by ejected bubbles are filled by further bubbles generated at 50A by nucleation or splitting and pushed 52A into the column. The driven out bubbles pass to respective limbs of a Y-junction 80A according to their chirality for annihilation 88A or enlargement, sensing and subsequent annihilation. Alternatively (Fig. 8, not shown) the driven out bubbles feed into two sensing limbs according to chirality and recombine for passage round a loop (106) to be reinserted at the top end of the column.  Details.-The lattice is initialized by generating bubbles at 22 and transferring them laterally by encoded energization of conductors A, B, C and complete lattice transfer to ensure that all sites are occupied; by applying a large inplane field and magnetically annealing, possibly using the drive conductors 42L, 42R of the column input/output ports to ensure full occupation; by heating the bubble supporting medium above its Curie temperature and bringing it into close proximity with an apertured permanent magnet; or by cutting generated stripes with a recording head or conductors (not detailed). The generator 50A includes an M-shaped conductor 58, 60, 64 of which a single one 58 or 60 is energized to nucleate a domain which is then split in two by energization of both conductors 58, 60.  The strip domains 30 in the buffer zones are generated by energization of both conductors 34A, 34B bordering the strip sites and lattice shifting is effected by energization of one such conductor to translate the strip laterally. Similarly, energization of only one of the column drive-out conductors 42L, 42R provides fine adjustment of the addressed lattice relative to the associated port.

Abstract: 1452306 Multistable state and logic circuits NIPPON ELECTRIC CO Ltd 12 Dec 1973 [13 Dec 1972] 57614/73 Heading H3T An asynchronous circuit element for a shift register comprises a three stable state circuit 1, a gate 2 for gating inputs from an external source to set the circuit 1 into either a first or a second state L 0  or L 1  and a control circuit 3 for performing the following functions: (i) bringing the gate 2 into its open state whenever the circuit 1 is in its third stable state L# so that the external signal can be applied to the circuit 1; (ii) closing the gate once such an external signal has been effected to set the circuit 1 to either state L 0  or L 1  ; (iii) generating an output signal indicative of completion of function (ii); (iv) cancelling the output on recept of a control signal. The three states of circuit 1 are: If initially circuit 1 is in the L 0  (or L 1 ) state and inputs 103, 104 are at the "1" level, then circuit 3 is in a state Q in which outputs 24, 25 are both at 1 level and gate 2 is closed. If input 10 now changes to "0" circuit 1 switches to the L# which switches circuit 3 to a state S in which a "0" level on output 24 opens gate 2. If L 1  (or L 0 ) is now written in by applying "0" on line 101 and "1" on line 102 (or via versa for L 0 ) the input to circuit 1 now has two "0" level signals and the circuit switches to a temporary state in which 21, 22, 23 are all "1" level. If input 103 is now switched back to its "1" level, the output of circuit 1 changes to L 1  (or L 0  depending on the inputs 101, 102) which sets circuit 3 to a state C in which a "1" level on line 24 recloses gate 2. A change in level on line 104 to "0" will now reset circuit 2 to its Q state and when line 104 reverts to its "1" state the whole circuit is back in its initial state, storing L 1  (or L 0 ). The circuit comprises NAND gates Fig. 2 (not shown) and forms a stage of a shift register Fig. 3 (not shown).

Abstract: 1411960 Integratee circuit structure SONY CORP 22 Dec 1972 [22 Dec 1971] 59419/72 Heading H1K In a monolithic integrated circuit comprising a plurality of junction isolated pockets of one conductivity type each including one or more resistors of the opposite conductivity type in which the resistors have different voltages applied to them, the pockets are likewise differently biased so as to maintain the junctions between them and the resistors therein reverse biased throughout while reducing to a minimum the extent of the associated depletion regions and hence the required spacing between the resistors and between them and the isolation walls. In Fig. 1 the two linear resistors 21, 22 in one pocket and the U-shaped resistor 24 in the other are surrounded by diffused N+ stop regions 23, 25, 26, to which biasing connections can be made. Conventional epitaxial deposition and diffusion steps may be used to simultaneously form the illustrated components and transistors &c in other pockets. If desired when forming the stop regions donor may be diffused into the resistors to reduce their thickness. In the voltage regulator of Fig. 2 (not shown) several resistors are formed in a pocket which also constitutes the collectors of two NPN transistors, while another resistor operated at a lower voltage is formed in a separate pocket. The full supply voltage is applied to the collectors while a lower voltage taken from an adjustable potentiometer tapping is supplied to the pocket accommodating the other resistor.
