Filed: 1991-11-28
Abstract: RD-20039 METHOD AND APPARATUS FOR CONVERTING CONE BEAM X-RAY PROJECTION DATA TO PLANAR INTEGRALS AND RECONSTRUCTING A THREE-DIMENSIONAL COMPUTERIZED TOMOGRAPHY (CT) IMAGE OF AN OBJECT Disclosed are procedures for converting x-ray cone beam data (line integrals through an object) to Radon data (planar integrals) for 3D CT image reconstruction by inverse Radon transformation. The radial derivative of each planar integral is determined by integrating to determine weighted line integrals along each of a pair of lines on a normalized detector plane, which lines are defined as intersections with the normalized detector plane of a corresponding pair of integration planes sharing a rotation axis and rotated with respect to each other by a rotation angle .delta..beta., and then dividing the difference between the weighted line integrals by the rotation angle .delta..beta.. The procedure can be employed to convert the cone beam data to values representing planar integrals on any arbitrary set of planes in Radon space, such as a set of coaxial vertical planes.

Title: Information storage apparatus
Inventor: NAKAMURA YOSHIMITSU
IPC: G11B20/18
Filed: 1991-12-13
Abstract: ABSTRACT     An information data storage apparatus stores one or more blocks of information data on a recording disc.  Each block is divided into a plurality of sectors. The disc has a main recording area and a secondary recording area.  After recording one or more blocks by a recording head, the same recorded area is scanned again for verification of the recorded data. If the verification detects defect sectors they are registered in a buffer.  After recording a number of blocks with a number of detected defect sectors registered in the buffer, the recording head moves to the second recording area to record the information data of the defect sectors.

IPC: C01B32/50
Filed: 1992-03-11
Abstract: An improved method and apparatus for regeneration and reuse of He-N2-CO2 mixed gas for carbon dioxide gas laser generator.   The mixed gas after use is contacted with a precious metal catalyst (for example, Pt-Al2O3) at a temperature of 200 - 300 °C to react CO and O2 so as to form CO2.   Poisoning of the catalyst by NO x is suppressed at this relatively high temperature of reaction.          Deterioration of the catalyst can be prevented to some extent by pretreating the catalyst prior to use, and the activity of the catalyst, even if decreased, may be recovered by reactivation.

Filed: 1992-07-07
Abstract: A communication protocol is proposed, to be used by a main station and a plurality of mobile sub-stations, while time slots are used in which data packets are transmitted. A  substation that has a message to be sent to the main station first transmits a request-for-access data packet to the main station.      If the sub-station knows its own position as well as that of the main station, the sub-station applies an advancement of time to the request-for-access data packet, so that this may be longer and contain more information, such as a self-selected recognition code and/or information relating to the length of the message to be sent. The main station measures the instant at which the request-for-access data packet is received relative to the time slot distribution and sends a correction of the advancement of time to the sub-station. After a send permission has been granted, the data packets are transmitted with a length essentially corresponding to that of the time slots, so that more information can be transmitted per data packet.
