Title: Mobile object communication system
Inventor: NAKAYAMA SATORU
IPC: H04W16/08
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of facilities by eliminating necessity to provide excessive facilities by varying the transmission output of each base station corresponding to the change of traffic quantity. SOLUTION: A center station 3 cyclically collects the traffic amounts of respective base stations from CPU 18 of respective base stations. When the center station 3 finds out any base station such as CS 2, for example, whose traffic exceeds a threshold, from the collected traffic amounts of respective base stations, a transmission output increasing instruction is outputted to a base station CS 1, for example, for which the traffic amount is least among the base stations around this base station CS 2.  The CPU 18 of base station CS 1, that receives this instruction, decreases the attenuation level of attenuator 16, expands its service area by increasing the output level of transmission signal and widens the area overlapped with the service area of base station CS 2 and the base station CS 1 takes charges of one part of communication of mobile object terminal in the service area of base station CS 2. Thus, the traffic of base station CS 2 is reduced less than the threshold and the communication of mobile object terminal is smoothly performed at all times.

Title: Screw conveyer-equipped water jet drill
Inventor: NAGASAKI SAKUJI
IPC: E21B7/18
Filed: 1992-10-27
Abstract: PURPOSE:To make it possible to drill a hole with high accuracy without generating noise even at high speed by installing a high pressure water injection part, a power motor, a screw conveyer, a drilling excavation part and a spray nozzle. CONSTITUTION:A high pressure water is injected into a high pressure water injection part 110 from a high pressure water generation device. As a result, the injected high pressure wafer forces a dynamic blade 122 of a drive member 120 which is a water motor to produce a rotary force to a rotary shaft 101, thereby providing rotary energy to the water motor. Since then, the projected high pressure water is forced to pass through holes 103 and 204 and ejected out at high speed and high pressure so that an excavation medium may be excavated. Passing through a screw of a screw conveyer 130 with the excavation medium contained, the water returns to the high pressure water injection part 110. The rotary force generated in the rotary shaft 101 makes firm and strong the excavation of a drilling medium driven by the drilling excavation part 140. This construction makes it possible to remove the excavation medium, highly accurate in dimensions and dig a hole without generating noise at high speed.
