摘要:
A position measurement system for measuring displacement of an observation station viewed from a reference station by receiving radio waves from satellites by these stations, and performing relative position measurement between the stations, having: a short period displacement measurement section for measuring a short period displacement component in each of the stations through independent position measurement; a relative position computing section for performing relative position measurement between said stations; a long period position computing section for inputting a short period displacement component measured by the short period displacement measurement section, a relative position determined by the relative position computing section and an absolute position from the reference station, and determining the absolute position including a long period displacement component by removing the short period displacement component measured by each of the stations; and a radio communication device installed on each of the stations, for transmitting/receiving data to/from another station.
摘要:
A measuring system wherein radio waves from a GPS satellite (4) are received by a reference station (1) and a plurality of mobile stations (3) to perform relative measuring among particular stations, thereby measuring the shift amounts of the mobile stations (3). At least one of the mobile stations (3) is disposed such that a baseline limit length allowing relative measuring relative to the reference station (1) is exceeded, and the intervals between particular mobile stations (3) are shorter than the baseline limit length allowing relative measuring. Each of the stations (1, 3) is equipped with a GPS receiver (11, 21) that receives the radio waves from the GPS satellite (4), and further equipped with a wireless communication apparatus (12, 22) that transmits/receives data to/from a particular station. There are provided a relative shift amount calculation part (32) for calculating the relative shift amount between the particular stations; and a reference relative-shift-amount calculation part (33) for determining, based on a reference relative-shift-amount of one station that performs a relative measuring, a reference relative-shift-amount of the other station.

The present invention provides a ceramic honeycomb structural body, and method for preparing the same, which can satisfactorily support a catalyst and can demonstrate superior mechanical strength, even if far thinner walls are used. Said structural body comprises lattice walls formed by a large number of cells 10 which are channels for fluid and a peripheral wall 12 which covers at least the circumference of said lattice walls 11. The outer peripheral portion 112 of said lattice walls 11 located in the vicinity of said peripheral wall 12 (area B) contain a densified portion of smaller porosity than that of an inner peripheral portion 111, of said lattice walls 11, which is located inside said outer peripheral portion 112 (area A).
