Abstract: There is provided a bathtub apparatus capable of satisfactorily detecting an electrocardiographic signal even in a state where water is being discharged into a bathtub by a water discharge device. The present invention is a bathtub apparatus (1) including a bathtub main body (2), a water discharge device (8) that discharges water toward inside of the bathtub main body and is provided above a first inner wall surface (2a) forming a short side of the bathtub main body, and electrodes (4a, 4b, 4c) attached to the bathtub main body to detect an electrocardiographic signal of a bathing person, where the electrodes are arranged on an inner wall surface of the bathtub main body, and are arranged closer to the first inner wall surface than a position (P) where water discharged from the water discharge device hits a water surface of the water stored in the bathtub main body.

Abstract: There is provided a bathtub apparatus in which a bather can confirm objective information in association with subjective information by history information based on a plurality of bathing histories. A bathing information system of the present invention includes a bather specifying unit, an information acquisition unit that acquires objective information, and program that controls a controller to store subjective information input by the bather in the controller, the program causing a controller to store a bathing history obtained by associating objective information A acquired by the information acquisition unit regarding specific bathing of a specified bather with subjective information B input by the bather specified for the specific bathing and causing the controller to implement an output function of outputting, to an output device, history information based on a plurality of bathing histories for the specified bather.

Abstract: The bathtub device of the present invention includes a water discharge part (8) provided on a bathtub main body, a circulation channel (4), a circulation pump (6) provided on the circulation channel, a temperature modification part (7), a sensing unit (22) for detecting a temperature of hot water in the bathtub main body, and a controller (16) for controlling the temperature of hot water, where the controller performs a water discharge temperature adjustment mode in which the temperature of hot water discharged from the water discharge part is reduced to within the predetermined temperature range, when the temperature is higher than an upper limit temperature of a predetermined temperature range, or a water discharge temperature adjustment mode in which the temperature of hot water is increased to within the predetermined temperature range, when the temperature is lower than a lower limit temperature of the predetermined temperature range.

Abstract: A manufacture support method for generating second design drawing data based on first design drawing data representing a configuration of a wire harness, includes the steps of: generating pieces of unique address information for nodes indicating dimension measuring points in the wire harness, respectively, and assigning the pieces of address information to respective nodes of a wire harness on the second design drawing data; and in determining numbers of the pieces of unique address information, assigning numbers to the respective nodes along a routing path of the wire harness.

Abstract: In a vehicle circuitry including an assembly of a plurality of wires and at least one joint point interconnecting the plurality of wires, a joint position determination assisting method assists an optimization of a position of the joint point. The method includes displaying visible information representing a wiring route and a configuration of the vehicle circuitry on a display screen based on basic design data representing the configuration of the vehicle circuitry, and in response to a designation of the joint point and an instruction for the optimization, calculating a length of each wire and a total wire length with the joint point being disposed at a plurality of mutually different positions, and outputting information representing an optimal position of the joint point, reflecting a result of comparison of the calculated total wire length at the respective positions.
