Title: Multiple electron beam and electron mirror memory apparatus  and method
IPC: G11C13/04
Filed: 1973-12-28
Abstract: 1438408 Cathode ray storage tubes MINNESOTA MINING & MFG CO 28 Dec 1973 [2 Jan 1973] 60053/73 Heading H1D Electron beam storage and retrieval apparatus includes electron source 4, magnetic prism 10, first electron storage mirror 6 which is electrically biased during the write mode to allow electron impingement at one of a plurality of storage areas determined by deflectors 19, 20 and is electrically biased during the read mode to modify the density of presented electrons in accordance with stored charges, and read-out means 12 for receiving electrons subsequent to the storage mirror during reading, source 4 being capable of producing a plurality of beams and control means ensuring all beams are presented during reading and selected ones during writing. More than one storage mirror may be included (e.g. mirror 8) allowing redundant storage for example. Fig. 1 also includes three element focusing lenses 13, 14, 15, 16, which also modify the cross-sectional size of the beam array, and objective lenses 18, 21 (e.g. three element and multi-apertured). Various sequences of operation are discussed for the double storage mirror system. Read-out array 12 may be a diode matrix with diodes connected individually, and in a row or in a column. The beam source of Fig. 2 (not shown) includes cathode (28), which may be a cold cathode and may have a radio-active or photoemissive surface, or may be a semi-conductor array (e.g. forward biased Si P-N junctions), and may have apertured masks (30), (60) and (90), and finger electrode control members (32), (33). The finger electrodes are on each side of an insulator base and joined by a conductive layer about the apertures. The writing beams may be controlled row by row or singly. Control of beams from photo-emissive elements may be by using an input light image corresponding to the information, formed by a neon light or LED array. In Fig. 3 (not shown) light sources (49) are focused on to photo-emissive elements (48). The source may alternatively be an array of field emitters (Figs. 4, 5, not shown) including emitting sites (50) in rows on separate emitting surfaces (51) on insulator substrate (52), insulating spacer (53) and parallel spaced accelerating surfaces (54) of thin foils or films of metal in crossed array permitting selective operation. The storage surface of mirrors 6, 8 may be a dielectric thin film (e.g. bismuth titanate, aluminium oxide or silicon dioxide) on a conducting substrate (e.g. a Si wafer). Prism 10 may be Helmholtz coils. Biasing of the outer three plates of lenses 18, 21 control cross-sectional area and the lens plates are positioned at one end of a tubular non-conducting sleeve (e.g. glass) (not shown). The innermost (fourth) plate removes stray electrons and is not biased. The patterns in the four plates are hexagonal. The above glass sleeve may also support the deflector units which may each be eight graphite coatings. Voltages and structural dimensions of the system are given. Operation may be at 10-8 torr.
Patent GB-1358190-A (GB)
Title: Semiconductor memory apparatus
IPC: G11C11/39
Filed: 1971-12-30
Abstract: 1358190 Transistor data stores WESTERN ELECTRIC CO Inc 30 Dec 1971 [31 Dec 1970 (3)] 60662/71 Heading H3T [Also in Division G4] Each of a plurality of memory cells 10, Fig. 1 consists of a transistor whose base is left opencircuit and one of whose junctions is biased to avalanche breakdown for long enough to cause holes or electrons to become trapped in the base region whereby to store a "1". Application of a positive pulse from one pulse circuit 20 (1-N, Fig. 2, not shown) and closure of a row switch to hold the emitter of the selected transistor at a fixed level such as earth, causes collector-to-base avalanche breakdown, and transistor conduction due to raising of the base potential. When the positive pulse ends, conduction stops, holes are trapped in the base region, and the negativegoing excursion of the base voltage resulting from the trailing edge of the pulse is partly negated by these holes to leave a voltage representing "1". To read, a voltage pulse smaller than the avalanche voltage is applied to the collector, and the collector-base and baseemitter capacitances C BC C BE  raise the base voltage sufficiently for normal transistor conduction to occur if a 1 is stored but not otherwise. A detector circuit 18 senses this conduction. In alternative embodiments, each cell is a PNP transistor and opposite polarities are used (Fig. 3, not shown); and in both these arrangements, the collector voltage may be opposite to that already described, to produce avalanche breakdown of the emitter-base junction instead of the collector-base junction. In another embodiment, using either PNP or NPN transistors (Figs. 4-6, not shown), a double emitter transistor is used for each cell, the extra emitter receiving the write pulse to be biased to avalanche breakdown and thereby to cause transistor conduction through the other emitter, which receives an opposite polarity pulse, the collector, and a collector resistor. In this case the transistor saturates, to enhance the carrier storage effect. The read pulse is also applied to the extra emitter, and a detector senses current from the first emitter if "1" is stored.

Title: Compressed-gas-operated Reciprocatng-piston Devices
IPC: F01N13/00
Filed: 1980-02-26
Abstract: A compressed-gas-operated reciprocating-piston device, e.g. a concrete breaker, rock drill or chipping hammer, has a cylinder comprising a rigid inner metal tube (40) in which the piston (12) reciprocates and a moulded outer sleeve (41) of rubber or plastics material, e.g. polyurethane, which surrounds the tube over the majority of its length and is bonded thereto.
