Title: Base station controller and handover control method
Inventor: IMAMURA YOSHIMASA
IPC: H04W36/18
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent traffic volume between both base stations arranged in mutually adjacent cells from being increased by setting up a condition for handover to be executed by a call and controlling the handover operation of the call on the basis of the set condition. SOLUTION: A handover system switching part 203 switches a system for executing different handover control in each call and a system for executing the same handover control in all calls. The former system executes handover control based on information set up and stored in respective parts in a connection condition setting part 204 and the latter executes handover control independently of the information. A storage part 205 for storing the number of base stations to be simultaneously communicated stores the number of base stations simultaneously communicated with the call at present which is determined to be controlled at its handover by a handover control part 202 and an allowable traffic volume setting part 206 optionally sets the upper limit of traffic volume allowed in each base station. Consequently handover control to a base station having much traffic volume can be inhibited.

In other word, the control valve 7 is closed, an amount of water in a second heat exchanger 4 is increased, a temperature of the flame is substantially decreased and its increase in temperature is restricted and then corrected to its decreased temperature. Then, in case that the temperature of the discharging gas is decreased, the cooling body 2 shows in turn its decreased cooling capability, a temperature of the discharging gas is gradually increased and then returned to its desired range of temperature. In this way, it is made possible to always keep the discharging gas of combustion within the thermal insulated space in a desired range of temperature.

IPC: D07B1/06
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To obtain a compact metal cord for reinforcing a rubber, enabling the light weightiness and the improvement of endurance of a tire, a conveyer belt, a high pressure hose, etc., and having a 2-ply twisted structure excellent in fatigue resistance. SOLUTION: This metal cord is obtained by twisting 2 metal filaments under maintaining pseudo helical wavy kinks having a winding direction of the wave same as the direction and the orientation of the twisting and having a pitch of 0.20-0.50 fold to the pitch of the twisted cord and 0.05-0.25mm height in the direction of the filament diameter besides the kinks caused by the twisting when twisting the 2 metal filaments imparted with the kinks. Since such metal cord absorbs an outside energy by a spring effect of fine kinks provided to each of the metal filaments to moderate the outside force applied to the filaments, a fatigue resistance to repeated simple bends or compression bends is improved.  Also, since the respective filaments contact discontinuously and a rubber can penetrate through spaces amount the contact parts, the rubber covering rate is increased and a corrosion resistance is also improved.
