Abstract: A planetary gear device is provided between a driving wheel and an energy accumulating device. A sun gear of the planetary gear device is connected to an input shaft of the energy accumulating device. A carrier of the planetary gear device is connected to the driving wheel. A torque adjusting device is connected to a ring gear of the planetary gear device. When a regeneration control is not carried out, the torque adjusting device is controlled by a control unit, so that a braking torque generated at the torque adjusting device and applied to the ring gear is controlled in order to make a difference of a rotational speed at a smaller value between the input shaft and the sun gear.

Abstract: A movable device includes an actuator element that deforms about an actuator axis in response to increase or decrease in energy of the actuator element. A driven body is coupled to the actuator element on the actuator axis and turned by deformation of the actuator element. A guide mechanism guides turning of the driven body about a turning axis coaxial with the actuator axis such that torsional deformation of the actuator element is directly transferred to the turning of the driven body.

Abstract: In an ejector, formed in a body is a swirling space which lets a high-pressure refrigerant flowing from a refrigerant inlet port swirl and introduces the swirling high-pressure refrigerant into a depressurizing space in which the swirled high-pressure refrigerant is depressurized and expanded. A passage formation member that defines a nozzle passage and a diffuser passage is shaped to have a cross-sectional area increasing with distance from the depressurizing space. Further, a temperature sensing unit of a drive device that displaces the passage formation member is housed in the body, and the temperature sensing unit and a diaphragm have annular shapes to surround at least the axial line of the passage formation member.

Abstract: An ejector has a swirling space, a pressure reducing space, a suction passage, a pressure increasing space, a nozzle passage, a diffuser passage, a passage forming member that forms the nozzle passage and the diffuser passage, and a vibration suppressing portion that suppresses a vibration of the passage forming member. The vibration suppressing portion has (i) a first elastic member that applies a load to the passage forming member in a direction in which an area of a cross section perpendicular to the direction of the central axis of the nozzle passage and the diffuser passage decreases and (ii) a second elastic member that applies a load to the passage forming member in a direction opposite from the direction in which the first elastic member applies the load to the passage forming member.

Abstract: An actuator device includes an actuator member, a drive subject, a drive device, and a tension applicator. The actuator member is configured to be deformed in response to application of energy to the actuator member from an outside of the actuator member. The drive subject is coupled to the actuator member. The drive device is configured to apply the energy to the actuator member and thereby displace the drive subject in a deforming direction of the actuator member. The tension applicator is configured to apply the actuator member a tension, which enables correction of a tension change generated by at least one of elongation and contraction of the actuator member that is induced by natural deformation of the actuator member.

Abstract: An ejector includes a shaft coupled to a passage formation member defining a refrigerant passage inside a body, and the shaft is slidably supported by a support member fixed to the body. A drive mechanism moves the shaft in an axial direction to change a passage sectional area of the refrigerant passage. The passage formation member is provided with a vibration suppressive member including a first mobile end that applies a load to enlarge the refrigerant passage and a second mobile end that applies a load to narrow the refrigerant passage. Both the first mobile end and the second mobile end are disposed on a same side of a slide region of the support member in the axial direction.

Abstract: An actuator that comprises a deformable material, an energy input part, and a characteristics change detection unit. The deformable material is configured with a polymer fiber and, by deforming in response to energy input from the outside, outputs motive power. The energy input part inputs energy to the deformable material. The characteristics change detection unit detects when the deformation characteristic of the deformable material has changed. The actuator also comprises a drive control unit that, by controlling the above-described energy, controls the output of the deformable material. When the characteristic change detection unit detects a change in the deformation characteristic, the drive control unit controls the energy in accordance with the change in the deformation characteristic.

Abstract: An occupant detection system may detect a state of an occupant in a vehicle compartment. The occupant detection system may photograph the vehicle compartment and generate an image. The occupant detection system may change an attitude in order to change a position of an imaging region within the vehicle compartment. The occupant detection system may estimate the attitude based on information included in the image and control an operation based on the estimated attitude. The sensor may be provided by an infrared temperature sensor. The image may be provided by a thermal image showing a temperature distribution of the vehicle compartment. The occupant detection system may store a correspondence relationship between a position of a specific temperature boundary included in the thermal image and the attitude. The occupant detection system may estimate the attitude based on the correspondence relationship.
