Abstract: In a control device, an instruction acquirer acquires an instruction to suppress in a specified period supplying of generated power generated by power generator installed in a power-consuming area to a commercial electrical power system. Upon the instruction acquirer acquiring the instruction, a water heater controller commands a water heater installed in the power-consuming area to perform a water heat-up operation when a predetermined condition is satisfied in the specified period.

Abstract: A fluid dynamic bearing device includes a housing injection molded with a bearing sleeve as an insert. Accordingly, the molding of the housing and the assembly of the housing and the bearing sleeve can be performed in a single step. In addition to this, by simply increasing the die precisions the housing and the bearing sleeve can be fixed easily with high precision. Since the housing is opened at both ends, it is possible to sandwich the bearing sleeve, and accordingly, the bearing sleeve can be accurately positioned inside the dies with reliability.

Abstract: To provide a fluid dynamic pressure bearing device that achieves high rigidity against moment without degradation in assembly precision and bearing performance, bearing sleeves are arranged in an axial direction and coaxiality of radial bearing surfaces formed on inner peripheral surfaces of the bearing sleeves is set to 3 ?m or less. This secures width precision between the radial bearing gaps to prevent a degradation in bearing performance and a failure such as wear etc. caused by contact between a shaft member and the bearing sleeves. Further, a first radial bearing surface and a second radial bearing surface are provided on at least one sleeve, and this allows a sleeve assembly constructed from the bearing sleeves to be supported at least three positions in the axial direction in a process of assembling the sleeve assembly.

Abstract: [Problems] Provided is a fluid bearing device in which bearing sleeves are positioned and fixed with respect to a housing with high accuracy. [Solving Means] To an inner periphery of a housing (7), a first bearing sleeve (8) and a second bearing sleeve (9) are fixed while being spaced apart in an axial direction. Between the bearing sleeves (8) and (9), a spacer (10) made of a resin is disposed. An axial rigidity of the spacer (10) is smaller than those of the first bearing sleeve (8) and the second bearing sleeve (9). Accordingly, in a state where the first bearing sleeve (8) and the second bearing sleeve (9) are positioned and fixed with respect to the housing (7), the spacer (10) is largely compressed in an axial direction compared to the bearing sleeves (8) and (9).
