摘要： PROBLEM TO BE SOLVED: To provide a display device, driving method, and a drive circuit of which power consumption can be reduced.
SOLUTION: There are provided an NMOS transistor 22 which connects a scan line COM to an earth potential part GND (potential VG) at ON, a PMOS transistor 23 which connects the scan line COM to a high potential part 20 (potential VC) for scan line at ON, an NMOS transistor 32 which connects a data line SEG to the earth potential part GND at ON, and a PMOS transistor 33 which connects the data line SEG to a high potential part 30 (potential VS) for data line at ON. When selecting the scan line COM, the NMOS transistor 22 is turned on while the PMOS transistor 23 is turned off, to connect the scan line COM to the earth potential part GND. When not selecting the scan line COM, both NMOS transistor 22 and PMOS transistor 23 are turned off, to make the non-selected scan line come into high-impedance state.

摘要： PROBLEM TO BE SOLVED: To provide a transmission power controller with which the transmission power of transmission signals to a plurality of mobile stations is controlled so as to reduce the interference of the transmission signals. SOLUTION: This transmission power controller is composed of a total transmission power observing part 1 for observing the total transmission power transmitted from a base station to the plurality of mobile stations and outputting an observe signal, a target total transmission power setting part 2 for calculating the suitable total transmission power value of the base station and outputting it as a setting signal, and a reference updating amount operating part composed of an adder 3, multiplier 4, adder 5, delay circuit 6, limiter 7, request SIR setting part 8 and adder 9. Thus, when the total transmission power of the base station exceeds the target total transmission power, corresponding to the difference, the target SIR of the mobile station can be updated. As a result, even when the number of mobile stations is increased and interference power is increased, the communication quality of all the mobile stations can be prevented from being uniformly degraded. Further, since the SIR of the mobile station is provided with an upper limit and transmission power can be prevented from being increased without the limit, the effect of interference power exerted upon the radio service area of the adjacent base station can be suppressed.

摘要： PROBLEM TO BE SOLVED: To arrange phases of demodulated data even in a propagation environment where a time difference among plural delayed waves is a 1 symbol time or over by controlling the phase of each delayed wave based on a demodulation symbol number and a reference symbol number. SOLUTION: A code length L of a spread code is selected to be a multiple of N of a correlation length T and data RS representing a symbol number being a reference when phases of demodulated data DM1, DM2 of delayed waves D1, D2 of demodulation sections 16(1), 16(2) are generated. In the case of demodulating a delayed wave Dn included in received data R, a number of a symbol being demodulated is detected by dividing a tip number of a demodulation use spread code with a correlation length T. Based on the demodulated symbol number and a reference symbol number, phases of the delayed waves D1, D2 are controlled. Thus, even in a propagation environment where a time difference among the delayed waves D1, D2 is a 1 symbol time or over, phases of the demodulated data DM1, DM2 are arranged.

摘要： PROBLEM TO BE SOLVED: To suppress the generation of skew and arranging inferiority in a medium by setting an arranging roller to a clamp state and setting a feed roller to a reset state to perform arranging operation. SOLUTION: When a medium 11 is inserted in an insertion port, the medium 11 is detected by a medium detection sensor 18 and, at the same time, an arranging roller 14 is set to a clamp state. Next, the arranging means of a main control part rotates the upper arranging roller 14 counterclockwise and the medium 11 is moved until detected by both leading end arranging detection sensors 19a, 19b and further moved after detected by both leading end arranging detection sensors 19a, 19b. In this case, it is supposed that the leading end of the medium 11 strikes against an arranging shutter 17 to complete arranging operation. Succeedingly, a feed roller 13 is set to clamp state and the arranging shutter 17 is opened and, after a pressure contact roller is set to a clamp state, the medium 11 is sucked. As mentioned above, the medium 11 is fed by point contact to be allowed to strike against the arranging shutter 17.

摘要： PURPOSE:To estimate a propagation path characteristic in an excellent way even when a propagation environment is fluctuated. CONSTITUTION:A Doppler frequency detection part 30 detects a Doppler frequency sequentially at a prescribed period based on a correlation signal V1(i) from which a data modulation component is eliminated. An SNR arithmetic section 40 calculates a signal versus interference wave power ratio sequentially at a prescribed period based on the correlation signal V1(i) and a reception signal V2. A degree decision section 50 decides a degree to minimize the estimate error by the least square method as the degree of the approximated function based on the output. An estimate value calculation section 60 uses the correlation signal V1(i) by the decided number of approximated data to calculate a parameter of the approximated function whose degree is decided by the least square method and calculates an estimate value V3(i) of the propagation path characteristic from the correlation signal V1(i) based on the approximated function having the parameter.

摘要： PURPOSE:To eliminate interference between multi-paths among other stations by generating a reception signal replica of each mobile station including the multi-path and eliminating the replica from the reception signal. CONSTITUTION:Correlation values S1-S3 are obtained by taking correlation between a reception signal R and spread codes (PN codes) of each station to make spread again thereby obtaining re-spread signals S1A1-S3A3. A replica RP is generated by sang the signals of all stations and a difference between the replica RP and the reception signal R is obtained. The correlation between the error signal E and PN codes A1-A3 of each station is taken to correct values S1-S3 to be Si=Si-epsiloni (i=1-3) corresponding to correlation values epsilon1-epsilon3. The replica RP is generated by using the corrected correlation values. The operation above is repeated to correct the correlation values so that the error is made zero. When data of the 1st station are obtained, the interference with respect to the signal of the 1st station is excluded by subtracting re-spread signals S2A2, S3A3 of the 2nd and 3rd stations from the reception signal. The similar processing is applied to the 2nd and 3rd stations.
