Abstract: A fluid pressure hitting device comprises a piston inserted in a cylinder, a chisel, and a first, second, and third chambers. The chisel is fitted in the cylinder such that a part of the chisel projects from one axial end of the cylinder and is configured to further project from that axial end due to being hit by the piston as the piston slides toward the one axial end. The first through third chambers are partitioned by an inner peripheral surface of the cylinder and an outer peripheral surface of the piston. The first through third chambers are arranged in the axial direction in order fluid the one axial end to another axial end of the cylinder. A flow path is configured to supply fluid from a fluid supply portion when the piston hits the chisel, to the first chamber.

Abstract: A power reception apparatus is installable in a vehicle and configured to receive electric power from a power transmission coil embedded in the ground. The power reception apparatus includes: a relay coil that is arranged on a tired wheel, which includes a tire and a wheel, and includes a first coil and a second coil; a power reception coil; and a power reception circuit. The first coil and the second coil are connected with each other by an electrical conductor. The first coil is arranged inside the tire. The second coil is located so that a distance from a central axis of the tired wheel to the second coil is shorter than a distance from the central axis to the first coil. The power reception coil is located so that when the first coil faces the power transmission coil, the power reception coil faces the second coil.

Abstract: A control system includes circuitry configured to: generate, based on a command profile representing a temporal change of a command for driving a controlled object and a response profile representing a temporal change of a state of the controlled object responding to the command profile, a first model representing at least a part of a relation between the command and the state of the controlled object; generate, based on the command profile, the response profile, and the first model, a second model representing another part of the relation that is not represented by the first model; generate, based on the first model and the second model, one or more control parameters representing a relation between a control reference and the command for causing the controlled object to follow the control reference; and control the controlled object to cause the state of the controlled object to follow the control reference based at least in part on the control reference and the one or more control parameters.

Abstract: A control system includes a storage that stores a computational model of a reference response profile representing a frequency characteristic of a reference state of a control target corresponding to a first command, and circuitry configured to calculate a first actual response profile representing a frequency characteristic of an actual state of the control target having responded to the first command. The circuity is further configured to acquire an error between the reference response profile and the first actual response profile, and cause a controller to output, to the control target, a second command that is based on a frequency at which the error is greater than a threshold. Additionally, the circuity is configured to calculate a second actual response profile representing a frequency characteristic of an actual state of the control target having responded to the second command, and update the computational model based on the second actual response profile and the reference response profile.

Abstract: The dialogue system includes a ranking determination unit configured to determine a priority ranking of the resulting sentence candidates on the basis of a degree of coincidence between the input key group and the storage key group, and a presentation unit configured to present a response for prompting a user to make an additional input on the basis of a resulting sentence candidate of a highest priority ranking. In a case where there is the stored keyword which is in a predetermined correspondence relation with the character string, the keyword acquisition unit acquires the input keyword obtained by adding additional information to the stored keyword. In a case where the additional information is added to the input keyword, the ranking determination unit reduces an influence of the input keyword to which the additional information is added on the degree of coincidence.

Abstract: A question inference device comprises: an input unit inputting an inquiry from a user; a storage unit storing a plurality of questions prepared in advance and one or more keywords for identifying each question in association with each other; a choice unit referring to the storage unit and choosing a question associated with a keyword contained in the inquiry inputted by the input unit from among the plurality of questions; a computation unit computing the likelihood of each of the plurality of questions for the inquiry inputted by the input unit; an inference unit inferring, based on a choice result of the choice unit and a computation result of the computation unit, such a question that the user intends the substance of the question from among the plurality of questions; and an output unit outputting information based on an inference result of the inference unit.
