Abstract: A single-phase to n-phase converter and a power conversion system are capable of easily connecting n (n represents an integer of 3 or greater) single-phase electric generators to an n-phase electric power system. The single-phase to n-phase converter includes n (n represents an integer of 3 or greater) single-phase electric generators, and a single-phase to n-phase transformer for converting n single-phase electric power outputs from the n single-phase electric generators into an n-phase system output, and then supplying the n-phase system output to a primary side of the single-phase to n-phase transformer. The n single-phase electric generators are connected to a secondary side of the single-phase to n-phase transformer.

Abstract: A system for commonly utilizing a vehicle in which illegal use of the vehicle can be surely prevented. In the system for lending a shared vehicle, which is parked in a parking area and of which the use information concerning lending and returning is managed, to a user after confirming permission to utilize the vehicle based on previously registered personal identification information, the shared vehicle is provided in the control section thereof with a popup key which can control whether a mechanical switch unit for starting the driving of the vehicle can be operated or not, and with an ignition mechanism control mean which permits starting operation of an ignition mechanism when personal cipher information inputted by the user matches personal cipher information imparted to the user in association with the personal identification information and the user sets a destination, and permits returning operation of the ignition mechanism when arrival at the set destination is detected.

Abstract: In a motor vehicle sharing system for managing motor vehicles parked in a parking area and renting the motor vehicles to users, the motor vehicle is provided with a detector for detecting the start and end of motor vehicle rental, and a usage data measuring section for starting and completing measurements for motor vehicle usage data. The detector contains a position detector for detecting the parking area. The motor vehicle is further provided with a membership list in which user information is recorded, a charge list, a rentability judging section for judging whether the motor vehicle is rentable, and a charging data generating section for making charging data by referring to the motor vehicle usage data measured by the usage data measuring section and the charge list Thus, it is possible to perform the rental and return operation without relying on a control center.

Abstract: A vehicle common use system for managing rental and return of a vehicle, the system. The system includes a usage charge computing device for receiving a remaining amount of fuel at a start of rental of the vehicle and a remaining amount of fuel at the return of the vehicle, from an in-vehicle terminal which is mounted on the vehicle and is connected via a communication network, and for giving a credit for fueling of the vehicle by a user when an increase in the remaining amount of fuel from the start of rental to the return, which is obtained by comparing both remaining amounts of fuel, is equal to or greater than a predetermined value. It is possible to encourage refueling of returned vehicles by the users and to reduce the burden on the maintenance staff.

Abstract: When a staff member reports a start of daily work from a portable terminal to a control center, a staff member controlling section which is included in the controlling section starts to handle the staff member. Also, a motor vehicle controlling section which is included in the controlling section acknowledges a maintenance condition of a shared motor vehicle which is recorded in a motor vehicle master and a port master and a partiality condition of the motor vehicles in each port so as to detect a staff member's job which is supposed to be done by the staff member and a port position in which the job is necessary to be done by the staff member. The staff member controlling section selects a staff member who can arrive at the port first in which a new job occurs according to the estimated job completion time at which the staff member completes the present job. A job notifying section which is included in the controlling section notifies the job to the portable terminal of the staff member.

Abstract: A vehicle managing device is provided with a control station of a vehicle use shared system in which a user ID number is compared with an ID number registered on an ID terminal owned by the user. The vehicle managing device includes a reservation information storage unit which stores vehicle reservation information of the user so as to relate to the user ID number; a vehicle reservation confirmation unit which confirms a presence of a reservation made by the user on a vehicle the user wishes to use by retrieving the reservation information storage unit using the user ID number transmitted from the vehicle; and a vehicle rental control unit which, if it is determined that the user has made a reservation on another vehicle, cancels the reservation made by the user and instructs rental permission to the vehicle the user wishes to use.

Abstract: After confirmation that a user is an authorized user by bringing a user certification into proximity to a user discriminating device, following the guidance of a touch panel display device, a battery is selected, and the battery, for which a lock thereof is unlocked, is taken out from a battery supply device. Thereafter, the battery is installed in a two electric wheeled vehicle in a parking apparatus, and the two wheeled electric vehicle is unlocked and used.
