Abstract: A magnetooptic data storage apparatus is described including a magnetooptic disk (30) with circumferentially-spaced-apart, radially-aligned embossed sector areas (60) which indicate data storage tracks. The sector areas include embossed signals (18) which indicate track-following information, and in a second area (15) which trails the track-following information, track-seeking information (20) is carried by the embossed signals. A magnetooptic coating covers the entire disk including the embossed sector areas. Readback clock synchronization signals are recorded over the track-seeking area to enable synchronizing a readback phase-locked loop such that more of the areas between adjacent sector areas can be used for recording data signals. During track seeking, the track seek controlling embossed signals are read using intensity demodulation, while in track following, during a readback, the clock signals recorded over the embossing are read for synchronizing the readback circuits. During recording, the synchronization signals are recorded over the embossed area dedicated to track seeking.

Abstract: A first image signal representing a radiation image of an object is obtained by exposing a stimulable phosphor sheet, on which the radiation image has been stored, to stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation, the emitted light being detected. A second image signal representing the radiation image is thereafter obtained by again exposing the stimulable phosphor sheet to stimulating rays, the light emitted by the stimulable phosphor sheet being detected. Read-out conditions, under which the second image signal is to be obtained, and/or image processing conditions, under which the second image signal having been obtained is to be image processed, are adjusted on the basis of the first image signal. A storage device stores information representing a standard pattern of radiation images. A signal transforming device transforms the first image signal representing the radiation image into a transformed image signal representing the radiation image, which has been transformed into the standard pattern. A condition adjuster is provided with a neural network, which receives the transformed image signal and feeds out information representing the read-out conditions and/or the image processing conditions.

Abstract: The present invention solves the problem of absorbing even considerable force components in the azimuthal axis, as well as of eliminating moments about the mirror axis at the point at which they are produced. Although such forces are scarcely able to occur statically on earth-bound telescopes, a rapid rotation about more than one axis can produce such moments, in particular if the mirror is operated in a mounting having three orthogonal drive axes. 
<??>The solution according to the invention comprises a hydraulic lateral mounting which acts at a plurality of points on the rear of the mirror. This mounting is adapted from the operating principle of a V mounting. The lateral V mounting can absorb all lateral forces within the V angle.

Abstract: A fiber-optic interferometric chemical sensor for detecting chemical vapors in the air. The chemical sensor 10 includes a light source 12 which outputs an optical signal to a first beam splitter 14. The first beam splitter 14 splits the optical signal into first and second components and transfers the optical signal over sensor and reference optical fibers 20 and 22 respectively. The optical fibers 20 and 22 are bonded to the sensor and reference magnetostrictive substrates 24 and 26, which oscillate in response to an oscillating electromagnetic field generated by a coil 28 circumscribing the substrates 24 and 26. In this way the optical fibers 20 and 22 are operable to change optical path length in response to the oscillating dimensional changes of the substrates 24 and 26. The sensor substrate 24 is further coated with a substance to facilitate collection thereon of molecules associated with the chemical vapor being detected. The optical outputs of the optical fibers bonded to the substrates 24 and 26 are then output to second and third beam splitters 16 and 18 respectively, and first and second beam combiners 32 and 34 respectively. The beam splitters 16 and 18 and beam combiners 32 and 34 operate cooperatively to provide an interferogram which is output to a signal processing circuit 44. The signal processing circuit provides an electrical signal indicative of the collection on sensor substrate 24 of molecules of the chemical vapor being detected, and outputs the signal to a display system 46.

Abstract: A method and apparatus for erasing an array of electrically erasable EPROM cells that avoids overerasure and allows programming or erasure of individual cells are provided. An erase line for each column of the array applies erase potential to the erase node of each cell in the column, provided that the erase node is connected to the erase line by a transistor controlled by a row select line. A sense amplifier determines when each cell begins to conduct and disconnects that cell from its erase line. By selecting a particular row, and then applying erase potential only to selected erase lines, a pattern of erased and programmed cells can be created in each row. The pattern differs from row to row depending on which erase lines have erase potential applied when that row is selected. Bias differences between erase and read modes assure that the erased cells, which have gone slightly into depletion, are not in depletion in normal operation.
