A rotator includes: a motor; and a brake that brakes the motor. The brake includes: a rotating plate that rotates with rotation of a shaft; a slide plate provided such that the slide plate can be slid in an axial direction of an axis of rotation of the motor in such a way as to approach and move away from the rotating plate; a spring that biases the slide plate toward the rotating plate; and an electromagnet capable of attracting the slide plate in a direction away from the rotating plate. The electromagnet includes: a yoke including an inner cylinder and an outer cylinder; and a brake coil. The yoke is disposed between the slide plate and a rotor in the axial direction. The brake coil is disposed adjacent to the rotor. When the brake coil is energized, the slide plate approaches both the inner cylinder and the outer cylinder.

Connector

A connector device comprises a connector and a mating connector. The connector comprises a housing and a slider having a second regulated portion. The mating connector comprises a mating housing having a second regulation portion. The connector is movable between an open position and a closed position. The slider is held by the housing to be movable between a first position and a second position. When the connector is moved to a predetermined position together with the slider which is located at the second position upon a movement of the connector from the closed position toward the open position, the second regulated portion is brought into abutment with the second regulation portion, and a movement of the connector toward the open position beyond the predetermined position is regulated. When the slider is moved to the first position, the connector is movable to the open position.

Connector device

A rotor includes a rotor core, first magnetic poles that respectively include a plurality of permanent magnets and have a first polarity provided by the permanent magnets, and second magnetic poles that are each formed between the permanent magnets adjacent to one another and are salient poles having a polarity different from the first polarity. &#x3b8;im and &#x3b8;is satisfy the relation &#x3b8;im&#x3e;&#x3b8;is. &#x3b8;om and &#x3b8;os satisfy the relation (&#x3b8;om&#xd7;1.1)&#x2265;&#x3b8;os&#x2265;(&#x3b8;om&#xd7;0.9). The rotor thus obtained can suppress increase in cogging torque while suppressing decrease in torque.

A power-circuit breaking device includes a receptacle and a plug. The receptacle includes a power terminal and a signal terminal. The plug includes a main terminal and a sub-terminal. The plug includes a plug housing, a lever which is attached to the plug housing, a lock slider which is attached to the plug housing, and a sub-connector which is supported by the lock slider. The plug housing holds the main terminal. The sub-connector holds the sub-terminal. When the lock slider slides, the sub-connector moves. When the lever is located at a closed position, the main terminal is connected to the power terminal. When the lock slider is located at a connected position, the sub-terminal is connected to the signal terminal.

The communication system according to the present invention includes: a mobile deviceconnectable to an LTE system and a 3G system; and an RNCconfigured to control mobility of the mobile devicebetween the LTE system and the 3G system. When the mobile device sends the RNCa request for connection to the 3G system instead of the LTE system because the LTE system imposes access restriction to restrict communication performed by the mobile device, the mobile deviceincorporates mobility information in the request for connection, the mobility information indicating that the mobile device hands over from the LTE system. In addition, when acquiring the mobility information from the mobile device, the RNCrestrains the mobile devicefrom handing over to the LTE system.
