A power supply apparatus 1 includes: a battery cell assembly 2 including battery cells 3 having a positive terminal 11 at one end and a negative terminal 12 at the other end; a busbar module 5 attached to the assembly 2 and configured to connect the cells 3 in series with each other; and a pair of electric wires 9 connected to electrodes 11, 12 taking out a voltage of the series-connected cells 3. The busbar module 5 includes: bus bars 6 configured to connect the positive terminal 11 and the negative terminal 12 of the mutually adjacent battery cells 3 of the assembly 2; a plate 8 disposed on the assembly 2 with the bus bars 6 attached thereto; and an electric wire holding portion 18 provided on the plate 8 configured to hold one electric wire 9a of the pair of the electric wires 9. The electric wire holding portion 18 extends in the arrangement direction X in which the cells 3 are arranged at a central portion of the plate 8 in the width direction Z orthogonal to the direction X of the battery cells 3.

A busbar includes a battery connecting portion and a wire connecting portion as a circuit body connecting portion. The battery connecting portion connects electrodes of two batteries to each other. The wire connecting portion is continued to the battery connecting portion, and connected directly with an electric wire so as to overlap a core wire of an electric wire thereon. The wire connecting portion includes a welding portion which the core wire of the electric wire is welded to, and a bridge portion connecting the welding portion and the battery connecting portion. A cross-sectional area of the bridge portion along an intersecting direction intersecting a direction of connecting the welding portion and the battery connecting portion is formed to be smaller than a cross-sectional area of the welding portion along the intersecting direction.

When a short-circuit failure of any of switch portions (13) including switch elements (11) and parallel-connected feedback diodes (12) of an inverter circuit (7) is detected during the operation of a motor (1), a switch portion (13) where the short-circuit failure has occurred is checked for whether it is on the positive polarity side or the negative polarity side. The switch elements (11) are so controlled that all the switch portions (13) on the same polarity side as where the short-circuit has occurred are brought into a conducted state and all the others are disconnected. This prevents a large electric current from flowing into each switch portion of the inverter circuit without requiring any switch to block the power distribution between a motor and the inverter circuit when a short-circuit failure of the switch portion of the inverter circuit occurs.

Provided is a digital broadcast receiving device (20) which can display a high resolution image longer without burdening users with a cumbersome operation. The digital broadcast receiving device (20) of the present invention switches, based on vehicle information, between switching thresholds by which switching is made between plural digital broadcast decoders outputting different digital broadcast images from one another in accordance with a reception state of digital broadcast waves. The plural digital broadcast decoders include, for example, a stationary reception decoder (200), which outputs a digital broadcast image for stationary receivers, and a mobile reception decoder (201), which outputs a digital broadcast image for mobile receivers.

A navigation system for guiding a moving object from a current position to a destination includes a setting device that sets the current position and the destination, a sensor that detects movement of the moving object, a computing device that calculates move distance that the moving object has moved from the current position based on data outputted from the detecting sensor, and that determines a position of the moving object by shifting the calculated move distance from the current position on path data between the current position and the destination, which has been obtained by a path planning. The navigation system further includes a display device for displaying path guidance information depending on the determined position of the moving object.

An information-transmission system which uses non-geosynchronous artificial satellites, including a server-system and its client apparatuses, for performing communications or broadcast, the system comprises: a means for controlling changeover of a non-geosynchronous artificial satellite being used, to another satellite to be next used; wherein the server-system determines whether or not a satellite-changeover occurs during sending of an information packet to be sent toward a satellite being used, one of the non-geosynchronous artificial satellites; and if it is determined that a satellite-changeover occurs during sending of the information packet to be sent, the server-system or each client apparatus postpones sending of the information packet to be sent, and starts sending of the information packet to be sent, after the completion of the satellite-changeover; or repeatedly sends the information packet to be sent, until the completion of said satellite-changeover. Moreover, the server-system informs each satellite on at least one of the start time of, the time necessary for, and the end time of the satellite-changeover.
摘要:
While a rotor 4 of a permanent-magnet rotary machine 1 is rotating and an armature current thereof is substantially zero, a motor controller 2 performs a dq vector control process to control the permanent-magnet rotary machine 1 in a dq coordinate system which has a d-axis representing the direction of a magnetic field of the rotor 4 and a q-axis representing a direction perpendicular to the d-axis, and determines a magnetic pole position correcting quantity θofs to correct a magnetic pole position θact detected by a magnetic pole position detector 8 so that a d-axis voltage command value Vdc determined by the dq vector control process will be substantially zero. The motor controller 2 controls the phases of armature voltages Vuc, Vvc, Vwc with magnetic pole positions corrected by the magnetic pole position correcting quantity θofs. Irrespective of whether the rotary machine 1 is a cylindrical machine or a salient-pole machine, the detected values of magnetic pole positions are appropriately corrected according to a simple process without the need for a voltage detector for thereby efficiently controlling operation of the permanent-magnet rotary machine 1.
