Title: Operation control method for cellular system using cost based on neighborhood relation
Inventor: BORST SIMON C
IPC: H04M3/00
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To attain effective allocation of dynamic channels by using a combination of hybrid of a measurement based DCA algorithm such as cost function based dynamic channel allocation DCA and of a reuse-distance standard algorithm. SOLUTION: A hybrid flexible channel allocation includes a measurement based dynamic channel allocation MBDCA part mounted at each cell site 102 and a cost function based dynamic channel allocation CFBDCA part of a reuse- distance standard mounted in a center data base of a mobile switching center MCB 104. At the MBDCA part, candidate channels defined to the flexible allocation are sequentially sent to the CFBDCA part operating via the center data base according to the usable up-link and down-link interference measurement value. Then a relevant channel selects one of allocation candidate channels based on its use degree set by a neighboring or nearby cell. Furthermore, a channel candidate list is collected at the site 102 based on the use information on the selected channel.

Abstract: PURPOSE:To obtain group III-V compound semiconductor single crystal of high quality by performing shape control using an angle of a shoulder part of a crystal in the direction of the crystal axis as a referential signal to form the shape of the crystal to a desired value in the course of crystal growth. CONSTITUTION:The weight and the pulling speed of a seed crystal are measured with a weight sensor 8 and a position sensor 9 as soon as the pulling of seed crystal is commenced. Both measured values are inputted continuously into an operation circuit 10, and the angle of the shoulder part of the crystal to be formed in accordance with the rate of increase of the crystal dia. is operated. The value of the angle is compared with the previously set shoulder angle, and a temp. compensation value signal corresponding to the difference of both shoulder angle values is inputted to a heat temp. adjustment circuit 11 and the temp. of the heater is adjusted so as to bring the angle of the crystal in the course of crystal growth to near the set value. By this method, a shoulder part having a smooth shape is formed and a semiconductor single crystal with a small dislocation distribution and superior characteristic is obtd.

Abstract: PURPOSE:To suppress disturbance noise and to prevent a plane position indicator (PPI) from the display of an image of the interference noise by making a receiving side insensible status temporally during the generation of interference noise due to a transmitted pulse wave from another radar device. CONSTITUTION:When a pulse is sent from a monostable multivibrator 18 in the 2nd radar device 10-2 to a video amplifier 16 and an interference signal due to the 1st radar device 10-1 reaches the video amplifier 16 in the 2nd radar device 10-2, the video amplifier 16 is controlled so as to be cut off by the pulse inputted from the monostable multivibrator 18.
