Abstract: An electric compressor includes: a compression part; an electric motor; an inverter; a housing including a plurality of housing forming members made of metal; a seal member that has an insulation property and is provided between the housing forming members adjacent to each other; and a potential equalization member that is made of metal and is in contact with both the adjacent housing forming members to equalize potentials of the adjacent housing forming members. The adjacent housing forming members include mating surfaces, respectively. An insertion hole is formed in one of the mating surfaces of the adjacent housing forming members, at a position in which the seal member is not provided. The potential equalization member includes an insertion portion inserted into the insertion hole, and a contact portion that is a plate portion extending in a gap between the mating surfaces and is in contact with both the mating surfaces.

Abstract: A terminal device includes a processor and a memory storing a program that, when executed by the processor, causes the terminal device to receive the broadcast information of a radio base station currently in communication with the terminal device, store location information included in the received broadcast information in a first storage part, and transmit the location information stored in the first storage part to a management apparatus connected to the radio base station through a network. The terminal device is caused to transmit the location information stored in the first storage part when the radio base station currently in communication with the terminal device is switched from a first radio base station to a second radio base station and location information is absent in the broadcast information of the second radio base station received by the terminal device.

Abstract: A management apparatus includes: a determination unit configured to determine whether or not terminal device identification information that is included in received terminal information is correct based on whether or not communication that uses communication module identification information of a terminal device including storage device identification information, included in the terminal management information, that is identical to storage device identification information included in the received terminal information and that corresponds to a terminal device other than a terminal device specified by terminal device identification information included in the received terminal information is established; and an update unit configured to update the terminal management information according to the received terminal information when the determination unit determines that the terminal device identification information included in the received terminal information is correct.

Abstract: An account management server, when a device executing a service receives a card ID read from an ID card, sends back log-on data as a response, which is recorded in an account management DB in a way that associates the log-on data with the card ID. A user terminal, when reading the card ID from the ID card, transmits the card ID together with an account name of a user to an account management server. The account management server overwrites, with the received card ID, the card ID registered in the account management DB in a way that associates the card ID with the received account name or password.
