Abstract: PROBLEM TO BE SOLVED: To enable route search at a high speed without degrading precision, by searching a route between a present place and a destination, on the basis of main road route data and each data of respective rectangular divided areas containing the present place and the destination. SOLUTION: If data of a present place P is inputted for example, data of a rectangular divided area (K 32515 for example) containing the place P is read, and link costs from the present position P to search start nodes N 32515-2 to 4 of K 32515 are computed. When this data is inputted when a destination is point Q for example near to a national road B3, data of a rectangular divided area containing position Q is read, and a link cost from point Q in this area to search start node is computed. In the case of route search for a national road, data containing routes near intersections of the national route is read out from a main adjacent node list in respective rectangular divided areas containing the present place P and the destination Q. A minimum cost between each intersection and the next is found and summed up, and a route of the smallest link cost is set for a guide route.

Inventor: KAWAHARA MASAKI
IPC: E21B25/00
Filed: 1993-10-07
Abstract: PURPOSE:To let a core hardly collapse, and pick up a core in an excellent condition. CONSTITUTION:An inner tube 22 and a spring adapter 31 are threadedly and coaxially engaged with the lower section of an inner head 21 via a spring mounting gap 31a. A preload working body 32 which is brought into contact with the head section of a picked-up core (rock core) so as to be moved, is slidably fitted in the axial direction within the lower section of the inner tube 22. A preload spring 33 is mounted in the inside of the inner tube 22 while being extended from the spring adapter 31 over to the preload working body 32. 4 cylindrical core is picked up in the inner tube 22 relatively in response to the amount of excavation by cutting the stratum with a knife edge with an outer tube 12 rotated. While a core is being picked up, the resiliency of the compressed preload spring 33 acts on the head section of a core from the preload working body 32, and natural preload is thereby applied to the core, so that the core is prevented from collapsing.

IPC: G01S7/527
Filed: 1989-09-29
Abstract: PURPOSE:To suppress reverberation suitably for the conditions of use of all active sonar apparatuses by a method wherein a reverberation spectrum generated by transmission is determined on each transmission and a band-rejection filter being suitable for this reverberation spectrum is employed. CONSTITUTION:A frequency analysis circuit 9 latches a transmission timing signal 14 sent from a transmission circuit 1 and a reception signal 15 obtained immediately after transmission and sends out reverberation frequency analysis data 16 to a band- rejection filter control circuit 10. The circuit 10 calculates from the data 16 an adaptable-type filter characteristic a rejection band width and a rejection central frequency for suppressing reverberation and sends out a filter control signal 17 to a variable band-rejection filter 11. In the filter 11, the central frequency is made to be f0' so that it is adapted to the frequency f0' of the center in a reverberation spectrum and, in addition, the filter characteristic is changed to be an adaptable-type filter characteristic having a rejection band width corresponding to the range of the reverberation spectrum. Thereafter, the filter 11 subjects the signal 15 to an appropriate processing for suppression of the reverberation for each frequency and sends out a processed signal 18 to a detection circuit 12. After detection, a reflection sound in the spectrum 25 exceeding a threshold value is detected by a gate circuit 13 and a target is displayed in a display for the like.

Abstract: PURPOSE:To make it possible to surely distinguish an icy road surface from a decayed paved road surface, by providing a plurality of receiver means having different directive angles so the intensities of reflected waves are compared to determine the condition of a road surface. CONSTITUTION:A control device 3 energizes an ultrasonic wave transmitting device 4 to emit ultrasonic waves from a transmitter microphone 5 onto a road surface W from which reflected waves are received by receiver microphones 7, 8. The thus received reflected waves are amplified by receiver devices 9, 10 and are then delivered to the control device 3. The control device 3 compares the intensities of the reflected waves to determine the condition of the road surface. In this case, it is possible to determine whether the road surface has a high friction coefficient or a low friction coefficient in accordance with whether the comparison difference between the intensities of the reflected waves exceeds a predetermined value or not. Thereby, it is possible to surely distinguish an icy road surface from a decayed paved road surface.
