摘要： 1,236,108. Uses of luminescence. WESTERN ELECTRIC CO. Inc. 23 Dec., 1968 [26 Dec., 1967], No. 60966/68. Heading C4S. [Also in Divisions G4 and HI] An optical memory comprises a solid twophoton fluorescent medium having at least two energy states at levels such that a radiative transition from a higher state to a lower state can occur, means producing a pair of energy pulses having a duration of a picosecond or less which coincide and overlap within a region of the medium to create in the region free radicals at an energy level intermediate the two states, and means for producing the radiation transition by increasing the energy of the free radicals to the higher state. A solidified fluorescent medium 12, which can be frozen or polymerized, is used as a two dimensional or three dimensional store. A laser beam pulse of frequency f 1 is deflected by deflector 15 and applied to the medium 12. A laser beam pulse of frequency f/ 2 = +¢f 1 is deflected and applied to block 12. The pulses are arranged to overlap at a particular memory cell 18 and have frequency and intensity such that both beams are required to excite electrons from level S o to level S 1 from where they undergo a non-radiative transition to level T 1 and produce free radicals which do not recombine because the medium is solid. Read out can occur by applying a collimated beam from an infra red source (e.g. CO 2 laser) to the cell to liquefy the cell, if the medium is frozen to cause the radicals to combine, undergo a non-radiative transition from T 1 to S 1 and allow electrons excited to S 1 to fall to one of the levels of S 0 accompanied by fluorescence which is detected. If the medium is polymerized frequencies f 3 , f4 of suitable intensities are used to create read-out in a similar manner. The two frequencies can be used to excite the free radicals to a level higher than level S 1 which is then reached by a non-radiative transition. In a further embodiment, one pulse source is used (e.g. a Nd : glass laser), the beam being applied to a frequency doubler to produce frequencies f 1 2f 1 which are applied to a variable delay delaying frequency 2f 1 more than f 1 . The memory cell block is backed by a mirror reflecting frequency f 1 but not 2f 1 so that the cell selected is that occurring when reflected frequency f 1 overlaps delayed frequency 2f 1 . The fluorescent medium may be anthracene, pyrene, 3,4-benzpyrene and may be polymerized by mixing the solid form with paranitrostyrene and liquid styrene, then heating. Alternatively it may be dissolved in benzene lowered to liquid helium temperatures.

摘要： A substrate for magnetic discs, which are to be used as external storage in data processors, is formed from glass-like carbon materials by themselves or contained in a thermosetting resin matrix. The glass-like carbon materials have excellent thermal resistance, can be finished to a mirror-like surface, and have less surface defects than aluminum substrates. Magnetic materials can be adhered directly onto the surface of such substrates shaped in the form of a disc. The resulting disc has good hardness, is resistant to elevated temperatures, is less likely to deform, and is low in cost.

摘要： Apparatus comprising in combination a first electron generator including focusing and scanning means for deflecting a primary electron beam to produce a bombarded scan pattern on a nonconductive medium, and control means including a second electron generator for generating a second electron beam of low energy electrons directed along an electron axis that is nonintersecting with the medium. The control means also including deflecting means to afford electron flooding of the medium by the low energy electrons and thereby cause secondary emission of electron from the medium, collecting means for collecting the secondary emission electrons to afford control of the accumulated charge on the medium, and light shield and trapping means to prevent illumination of the medium by the second electron generator. In the first embodiment, the medium is photon emissive and the apparatus includes a photomultiplier. In the second embodiment, the medium is sensitive to the bombarding electrons for producing a pattern thereon.
