摘要： For controlling a traction motor of a vehicle, a current command value is determined based on a torque command and a load value representative of running load of the vehicle. A voltage command value is calculated in such a manner that a difference between the current command value and the actual current of the motor is converged to zero. An allowable range is determined for the voltage command value based on the load value and physical quantity associated with an operating condition of the motor. The voltage command value is compared with the lower and upper limits of the allowable range. A safeguard is set on the voltage command value when the latter is becoming smaller than the lower limit or greater than the upper limit. Preferably, the current command value is scaled down or scaled up depending on the voltage command value relative to the allowable range.

摘要： A photodetector group includes a plurality of photodetector elements which are arranged one-dimensionally in a direction of movement of a scale. An optical encoder includes a differential signal calculating member which calculates a first differential signal of an output signal from one photodetector element and an output signal from other photodetector element, and a gate signal forming member which generates a gate signal which includes an area of zero crossing by the first differential signal, near a position where light emitted from a light source is incident on the photodetector group upon passing through a reference position pattern formed on a scale. The optical encoder outputs a reference position signal based on a point of zero crossing of the first differential signal and the gate signal.

摘要： A computer network system for implementing a web page providing method is composed of a personnel management system of a user, terminals operated by respective employees belonging to the user, and a server, which are connected to each other via a network. The server stores an employee management table defining the respective roles of the employees' a content management table listing URLs for contents to be provided to the employees, a roll management table defining providable contents and conditions for providing the contents for every role, and a displaying attribute management table defining a work schedule of each of the employees. These tables are updated whenever new data is received from the personnel management system. If a portal screen is requested from a terminal operated by any one of the employees, the web page providing program stored in the server causes a CPU to generate an HTML file for displaying, on the terminal, the portal screen incorporated with only the contents that can be provided in accordance with the conditions recorded in the individual tables and to transmit the HTML file to the terminal.

摘要： To cancel in-phase components acting on vibrators of first and second sensor units in an angular velocity sensing direction Y, a differential amplification circuit obtains a differential waveform between a first angular velocity sensing waveform J1 and a second angular velocity waveform J2. Furthermore, to reduce a residual in-phase component of the obtained differential waveform, input gain adjusting circuits adjust an input gain of the first angular velocity sensing waveform J1 and an input gain of the second angular velocity sensing waveform J2 before these waveforms J1 and J2 are entered into the differential amplification circuit.

摘要： A motor control apparatus calculates a current command value based on a torque command value and a rotational speed of the traction motor, and calculates a voltage command value based on a difference between a detected current of a traction motor and the current command value so as to reduce the difference to 0. In addition, the motor control apparatus calculates a preferable voltage range of the traction motor with reference to the torque command value and a motor speed, and performs a feedback control so that the voltage value supplied to the traction motor is within this preferable voltage range.
