Abstract: The present invention makes possible recording motion pictures accurately starting at a point where a start recording event is received. The recording includes those pictures prior to the start recording event using a picture compressing method that compresses pictures both before and after the starting event, typically using the MPEG2 compression system. To make the above recording method possible, the present invention provides a signal processor and a photographic device that can search a motion vector for changing the object searching range properly, set an compression amount allocation for each picture type, and allow optimized parameters to be set when a start recording event is generated. The pictures processed before the start recording event is generated are stored in a memory buffer and on a recording medium so as to be used for recording or reproduction data entered after the recording starting time.

Abstract: The present invention relates to a process for producing a bis(4-hydroxy-3-nitrophenyl) compounds, characterized by nitrating a bis(4-hydroxyphenyl) compound wherein two phenyl groups are bonded to each other directly or through an electron-donating bridging group, sulfoxide group, sulfone group or carbonyl group in an inert solvent using nitric acid under the condition of substantially free from any other acid. According to the process, the target compounds reduced in the content of trinitrates can be produced in high yield and further recrystallizing the compound easily gives in high yield a high-purity products suitable for use as a raw material of producing a heat-resistant polymer and so on because the content of a trinitro-substitued compound in that compound is low.

Abstract: A PET apparatus is provided, which ensures excellent quantitativeness by properly correcting the influence of scattered radiation while improving the resolution of a reconstructed image and keeping good photon pair detection sensitivity. A determining section 52 determines whether a straight line connecting the light-receiving surfaces 15b of a pair of photon detectors 15a which have simultaneously detected a photon pair crosses any one of slice collimators 21n. When it is determined that the straight line crosses none of the slice collimators 21n, the corresponding coincidence counting information is accumulated by a first coincidence counting information storage section 53 to generate a signal sinogram. When it is determined that the straight line crosses one of the slice collimators 21n, the corresponding coincidence counting information is accumulated by a second coincidence counting information storage section 54 to generate a scatter sinogram.

Abstract: The energy E of a signal pulse P inputted to an energy measurement apparatus 1 for measurement, and corresponding to the total integrated intensity, is calculated in an energy calculation unit 10 from the integrated signal intensity Q acquired by a gate integrator 32, and from the pulse interval T measured by a pulse interval measurement unit 23. At this time, pileup correction is performed using at least one of the integrated signal intensity or the energy, and the pulse interval of the signal pulse inputted prior to the signal pulse for measurement. By this means, the correct energy E, with the effect of pileup eliminated, can be determined with good precision. Hence a method and apparatus for energy measurement are realized which enable correct and precise measurement of the energy of individual signal pulses, even when the pulse interval between signal pulses is short.

Abstract: Two .gamma.-rays accompanying position annihilation are incident into .gamma.-ray detectors in detector arrays set with a measured object inbetween. Electric pulse signals output from the .gamma.-ray detectors are supplied to an annihilation presuming unit, which obtains a presumable event of positron annihilation by the coincidence counting conditions and which notifies an image reconstructing unit of annihilation occurrence notification and information of detectors. Electric pulse signals output from the .gamma.-ray detectors are supplied to a time-of-flight difference measuring unit, which measures a difference of detection time between the detectors and notifies the image reconstructing unit of it. The image reconstructing unit obtains a presumable annihilation position based on the received information and stores it. A tomographic image of a specific portion is obtained by an algorithm for substantially compensating measurement errors, for example by the iterative process with the stored information.
