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.

Abstract: A method for producing a conjugated diolefin that can suppress reaction byproducts with high boiling point from remaining in steps following a quenching step by a quenching tower, and producing a conjugated diolefin (e.g., 1,3-butadiene) that can be used as a raw material for synthetic rubber, resin and the like, even when using an industrial grade mixed hydrocarbon that may not necessarily have a high purity as a raw material to produce the conjugated diolefin (e.g., butadiene). The method includes a step of producing a product gas by reaction containing a conjugated diolefin by feeding a hydrocarbon containing a monoolefin having 4 or more carbon atoms and oxygen to a reactor accommodated with a catalyst containing a metal oxide and a carrier, and a step of sending the product gas by reaction to a quenching tower and washing with a quenching agent (e.g., an organic amine aqueous solution).
