摘要： An inverter apparatus for converting a DC power converted from an input AC power to an output AC power of a variable frequency and a variable electric power to drive an induction motor at a variable speed. The inverter apparatus includes a rectifying unit, a filter capacitor, an inverter unit having an input connected across the filter capacitor, an input current detector and a gate circuitry for driving the inverter unit. An excitation current detection unit detects an excitation current of the induction motor from an output signal of the input current detector, a gate signal for driving the gate circuitry and a reference phase command. A setting unit sets a limitation level of the excitation current, a torque boost voltage command unit produces a torque boost voltage command, and a torque boost voltage compensation unit changes the torque boost voltage command so that the detected excitation current value is smaller than or equal to the limitation level.

摘要： Induction voltage command Em* is obtained from inverter's primary frequency command &ohgr;1* and torque boost voltage commander produces torque boost voltage command &Dgr;Vz* in accordance with &ohgr;1* while integrator produces reference phase command &thgr;d*. uvw/dq converter detects motor excitation current Id (equivalent of no-load current). Next, deviation of excitation current limitation level command Idmax* and detected Id is inputted to limiter processing unit to produce torque boost voltage compensation value &Dgr;Vc for varying &Dgr;Vz* so that Id is smaller than or equal to Idmax*. Inverted &Dgr;Vz* is set up as a lower limiter value of the limiter processing unit. Next, &Dgr;Vc and &Dgr;Vz* are added to produce final compensated torque boost voltage command &Dgr;Vt* and &Dgr;Vt* and Em* are added to produce q-axis voltage command Vq* of the inverter output voltage.

摘要： An astrocyte-specific drug carrier containing a retinoid derivative and/or a vitamin A analog as a constituent; a drug delivery method with the use of the same; a drug containing the same; and a therapeutic method with the use of the drug. By binding a drug carrier to a retinoid derivative such as vitamin A or a vitamin A analog or encapsulating the same in the drug carrier, a drug for therapeutic use can be delivered specifically to astrocytes. As a result, an astrocyte-related disease can be efficiently and effectively inhibited or prevented while minimizing side effects. As the drug inhibiting the activity or growth of astrocytes, for example, a siRNA against HSP47 which is a collagen-specific molecule chaperone may be encapsulated in the drug carrier. Thus, the secretion of type I to type IV collagens can be inhibited at the same time and, in its turn, fibrosis can be effectively inhibited.

摘要： A vehicle includes a first drive device and a second drive device. The first drive device includes a motor, a motor control device, a connection-disconnection device, and a connection-disconnection device controller. When the vehicle is driven in a state where a driving force of the first drive device is substantially zero, or the vehicle is driven only by a driving force of the second drive device, the connection-disconnection device controller couples the connection-disconnection device to establish a connected state of the connection-disconnection device. The motor control device is configured to perform loss reduction control on the motor to reduce at least one of a loss of the motor and a loss in a power transmission path in power transmitted to the first driving wheel, by establishing the connected state of the connection-disconnection device.

摘要： After a selection key bundle is determined by a selection key bundle determining process, the following first authentication key authenticating process is executed. An authentication processing part selects a selection encryption key from selection key bundle following a predetermined association based on a received random-number data. On the other hand, another authentication processing part selects an encryption key from the selection key bundle as a selection encryption key, following the association based on the received random-number data, encrypts the random-number data using the selection encryption key so as to acquire encrypted random-number data and transmits to the former authentication processing part. The former authentication processing part decrypts the encrypted random-number data using the selection encryption key so as to acquire decrypted random-number data and then determines whether that authentication is acceptable based on a comparison between the transmission time original random-number data and decrypted random-number data.
