Abstract: A rotary electric machine includes a stator. The stator has a coil end provided by a plurality of joint portions. The coil end has a leader wire connected to a power terminal. The stator has a coil end provided by a plurality of turn portions. The coil end has a circumferential pair whose top portions are offset in a circumferential direction. The circumferential pair has a height HG21. The coil end has an axial pair whose top portions are offset in an axial direction. The axial pair has a height HG22. The housing has a facing surface facing the coil end. The coil end provides a height distribution which adapts an unevenness of the opposing surface.

Abstract: A wireless connector for wirelessly transmitting a to-be-transmitted target that is electric power and/or information, has a first unit and a second unit removably attached from the outside of a first object and a second object, respectively. The first unit includes a first transmission/reception part for wirelessly transmitting the to-be-transmitted target; and a first housing to which a first connector part for transmitting the to-be-transmitted target to/from the first object by being attached to the first object is fixed. The second unit includes a second transmission/reception part for wirelessly transmitting the to-be-transmitted target to/from the first transmission/reception part; and a second housing to which a second connector part for transmitting the to-be-transmitted target to/from the second object by being attached to the second object is fixed.

Abstract: A wireless connector is composed of a pair of units. Each unit includes an annular transmission/reception unit which is provided with a coil used to wirelessly transmit electric power, and formed of a plurality of coil parts, and a main connector portion which is detachably attached to an object from the outside of the object to transmit the electric power to the object. Each unit is assembled such that each unit can be divided into a plurality of non-annular pieces so that the coil can be formed by coupling the plurality of coil parts via a plurality of connectors for coil. When one of the transmission/reception units is attached to the object, the one of the transmission/reception units is arranged so as to oppose the other one of the transmission/reception units in a non-contact manner such that electric power can be wirelessly transmitted therebetween.

Abstract: A wireless connector includes: a first unit attached detachably from the outside of a first object; and a second unit attached detachably from the outside of a second object. The first unit includes a first housing to which a first transmission/reception part and a first connector part are secured, the first connector part being attached to the first object and transmitting a to-be-transmitted target between the first connector part and the first object. The second unit includes a second housing to which a second transmission/reception part and a second connector part are secured, the second connector part being attached to the second object and transmitting a to-be-transmitted target between the second connector part and the second object. The first transmission/reception part and the second transmission/reception part are arranged so as to be separated from each other and opposed to each other to wirelessly transmit the to-be-transmitted target.

Abstract: A sensor module of the present invention includes a flexible body and a sensor fixed to the outer surface of the body. The body is attachable to a robot hand having multiple fingers and is removable from the robot hand. The sensor is a proximity sensor or a tactile sensor. A position on the body where the sensor is fixed corresponds to a fingertip of a finger of the robot hand in a state where the sensor module is attached to the robot hand. The body has the shape of a glove, a finger cot, or a sheet.
