Abstract: PURPOSE:To increase the reliability of omega receiver, by detecting the specific signal of omega signal from each station received by the omega receivers using time signal. CONSTITUTION:The omega signal incoming from each station is received 1 and it is delivered to the segment synchronisum circuit 2. The circuit 2 distributes the omega signal received in time sharing manner in the same frequency every station signal and it is made at the segment synchronism waves delivered from the segment synchronous wave production circuit 3. In the station synchronous wave delivered from the circuit 3, arbitary synchronous wave is delivered to the coincidence detection circuit 4. On the other hand, the satellite navigation receiver 5 receives the navigation signal which is transmitted from the artificial satellite and to measure the position of the ship inself. After detecting 6 the time signal and delaying 7 for a given time, it is delivered to the circuit 4. Accordingly, while the synchronous wave to the circuit 4 is in agreement with the scheduled station signal, the synchronizing signal and the time signal delayed 7 are in agreement. Further, based on the result of the agreement detection 4, the display unit 8 displays whether the synchronous wave and the time signal are in agreement in timing or not.

Title: Ground-improving work
Inventor: OYA HIROSHI
IPC: E02D3/10
Filed: 1990-04-10
Abstract: PURPOSE:To permit a water-permeating layer of a high dehydrating function to form by a method in which high-pressure water containing sand is jetted from the nozzle of a rod with holes to a given depth and replaced by sand having high water permeability to form a horizontal water-permeable layer artificially. CONSTITUTION:A mixed fluid consisting of high-pressure water and sand is downwardly jetted through a nozzle 3 from the upper part of a double tubular rod 1, during which period the rod 1 is turned to excavate to a given depth. Sand of high water permeability is packed into the pit to form a sand column 17. While turning the nozzle 3 horizontally, the ground is excavated into a disk form, and the water in the pit is displaced by sand of high water permeability while regulating the jet pressure of high-pressure water containing sand to form a horizontal water-permeable layer 18 artificially. The pit 5 is further packed with sand of high water permeability and finally water is pumped up for ground improvement. Sand separated from mud water in the bit 4 by a sand separator 7 is sent out to the rod 1 for reuse. Water-permeable layer can thus be artificially formed over a wide range to greatly improve the dehydrating function.
