Abstract: This invention is to provide an improved device for measuring torque with high accuracy and a simple structure. The device is so constructed that one end of a torsion bar (which is twisted depending on an actual steering operation) is combined with one end of an input shaft, while the other end of the torsion bar is combined with one end of an output shaft. The other end of the input shaft is combined with a steering wheel, while the other end of the output shaft is connected to vehicle wheel. A rotor of a first resolver comprising the rotor having a resolver excitation winding and a stator having a resolver output winding is fixed to the input shaft (one end of which is combined with the steering wheel). A rotor of a second resolver comprising the rotor having a resolver excitation winding and a stator having a resolver output winding is fixed to the output shaft (the other end of which is connected to the vehicle wheels).

Abstract: A hard carbon film (15) is formed directly or through an intermediate layer for enhancing adhesion over an inner surface (11b) of a guide bush (11) for holding a workpiece (51) rotatably and axially slidable on an automatic lathe at a position near a cutting tool, to be in sliding contact with the workpiece (51) or directly or through an intermediate layer for enhancing adhesion on the surface of a superhard lining fixed to the inner surface (11b) The guide bush (11) has remarkably enhanced durability and prevents damaging the workpiece (51) and seizing that makes a machining operation impossible even when the guide bush (11) is used for an extended period of time and when the automatic lathe operates for heavy machining.

Abstract: A first reception power measuring section 206 measures reception power of individual channel signals transmitted with a narrow directivity, and a second reception power measuring section 207 measures reception power of common channel signals transmitted with a wide directivity. A determining section 210 determines the presence or absence of a directional shift based on an average reception power of the individual channel signals and an average reception power of the common channel signals. A transmission power controlling means 211 performs transmission power control based on the determination result. This makes it possible to correctly determine the cause of a reduction in reception power and to control transmission power accurately.

Abstract: In the CDMA Radio Multiplex Transmission, transfer function of line is inferred by using common pilot signal and synchronous detection is performed accordingly. The transmitting end transmits by periodically inserting pilot symbols into one channel only of multiplexed channels. The receiving end infers line condition (transfer function) from the received pilot symbols and, on the basis of the information thus obtained, performs synchronous detection of each channel multiplexed.

Abstract: An electronic apparatus includes a master chip for writing correction data, which is input from an external communication controller via an external bus, to an EEPROM. After a system reset, the master chip reads the correction data written to the EEPROM. If it is determined that the data read from the EEPROM is the correction data, the master chip replaces a portion to be corrected in an existing program with the read correction data and downloads (uploads) a corrected program into a slave chip.

Abstract: A small number of users who provide high interference in the other users, such as a user transmitting a high rate signal, are selected beforehand. First, a signal of the user is demodulated to generate a replica, and a difference between a received signal and the replica is calculated, thereby canceling the interference in signals of the other users, and further improving the system capacity.

Abstract: Symbol 102 that is spread with the only short spreading code and inserted in synchronism with a long spreading code is specified by detecting the correlation with only the short spreading code. Next, another short spreading code indicative of a timing of reverse and forward link switching is specified, where the short spreading code is multiplexed at the same position as that of the detected symbol. The detection of the symbols spread with only these spreading codes enables to acquire synchronization of the long spreading code, synchronization of switching of reverse and forward links, and synchronization of a transmission frame. It is thereby possible to reduce synchronization acquisition time for the long spreading and an easy planning of base station locations without decreasing the frequency utilization efficiency.

Abstract: Spreading sections of the base station spread the respective distributed data using mutually orthogonal spreading codes and are transmitted from antennas. Despreading sections of the mobile station despread the received signals using the same spreading codes as those used at the base station. Demodulation sections demodulate the despread signals. Received signal power measuring sections measure their received signal powers from the demodulation result. A received signal power combination section combines the measured received signal powers and a transmit power control section controls transmission power based on the combined received signal power. When carrying out diversity reception through a plurality of antennas at the base station, transmit power control errors are suppressed to a small level at the mobile station.

Abstract: An adder 201-1 adds a signal selected by means of a switch 101, being a signal in which pilot symbol and demodulated data symbol replica signals have been eliminated from a received signal, and a pilot symbol replica signal output from a replica signal buffer 112. A matched filter 202-1 detects the correlation between the output signal from the adder 201-1 and the spreading code assigned to user 1. A delay profile creator 203-1 creates a delay profile at the point at which a timing signal is input, and makes a threshold value decision for the correlation value, thereby estimating the reception timing of each path. By this means, it is possible to estimate reception timings with high precision and achieve improved reception quality.

Abstract: Spreading sections 104 and 105 of the base station spread the respective distributed data using mutually orthogonal spreading codes and they are transmitted from antennas 106 and 107. Despreading sections 202 and 203 of the mobile station despread the received signals using the same spreading codes as those used at the base station, demodulation sections 204 and 205 demodulate the despread signals, received signal power measuring sections 207 and 208 measure their received signal powers from the demodulation result, received signal power measuring section 209 combines the measured received signal powers and transmit power control section 212 controls transmission power based on the combined received signal power. When carrying out diversity reception through a plurality of antennas at the base station, this suppresses transmit power control errors to a small level at the mobile station.

Abstract: A determination section 301 determines whether or not a DSCH has been assigned to the communication terminal apparatus in question, and outputs a signal indicating the result of that determination to a transmission controller 102, and the transmission controller 102 changes as appropriate the degree of frequency of transmission of a signal containing shared channel information according to the result of determination by the determination section 301. That is to say, the transmission controller 102 outputs a signal containing shared channel information to a modulator 103 with a high degree of frequency when the DSCH has been assigned to that terminal, and outputs a signal containing shared channel information to the modulator 103 with a low degree of frequency when the DSCH has not been assigned to that terminal.

Abstract: Error detection section 109 carries out error detection using demodulated data and outputs an error rate to SIR versus error rate estimation section 110. SIR versus error rate estimation section 110 estimates an SIR versus error rate and outputs the result of decision as to whether the correction of the target SIR value is necessary or not to target SIR correction section 111. Target SIR correction section 111 corrects the target SIR value based on the decision result. The information on the demodulation capability of a BTS is output to G parameter control section 112 and G parameter control section 112 determines an optimal gain factor. A G parameter indicating the determined gain factor is output to multiplexing section 107 of the BTS. The G parameter is output to SIR versus error rate estimation section 110.
