Filed: 2002-04-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a mobile communication system capable of improving the system throughput.  <P>SOLUTION: A base station 1 divides one cell into three sectors and uses an adaptive antenna to transmit a common pilot channel to a plurality of mobile stations in each sector by means of beams 101 to 103 the directivity of which is controlled by the adaptive antenna. On the other hand, when a mobile station 2 makes data communication with the base station 1, the base station 1 transmits a data channel and an individual control channel to the mobile station 2 by using a beam 201 the directivity of which is individually controlled. The mobile station 2 switches the common pilot channel and the individual control channel from the base station 1 to estimate the quality of communication paths.  <P>COPYRIGHT: (C)2004,JPO

Title: Method for adjusting supercharging pressure limitation of turbocharger in internal combustion engine in relation to density of ambient air
Inventor: WEINREUTER BERNHARD
IPC: F02B39/16
Filed: 2002-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a method for adjusting supercharging pressure limitation of a turbocharger in an internal combustion engine in relation to density of ambient air in the internal combistion engine. SOLUTION: Values of a primary ambient temperature T∞ , primary ambient pressure P∞ , a suction air flow rate ML, and supercharging pressure PL are calculated at prescribed time intervals in this operation state. Primary pressure PVE and a primary temperature TVE of a compressor inlet are calculated by a corrected performance curve of a function of a predetermined air flow rate from these values. An air flow rate MLkor of the compressor inlet corrected each time by standard condition of a compressor is calculated from the calculated pressure PVE, temperature TVE and suction air flow rate ML of the compressor inlet.  Maximum allowable supercharging pressure PLmaxkor related to a compressor rotational speed is obtained by the air flow rate MLkor and the ambient pressure P∞ of the compressor inlet corrected by the standard condition of the compressor, and compared with supercharging pressure PList calculated in this operation state. The supercharging pressure is adjusted so that a calculation value of the supercharging pressure PList becomes the maximum allowable supercharging pressure PLmaxkor or less of a function of the compressor rotational speed calculated each time by this condition.
