Abstract: An electrostatic chuck includes a ceramic dielectric substrate and a base plate. The ceramic dielectric substrate includes a first major surface, a second major surface, a groove part, and a plurality of cooling gas holes. The groove part includes first and second circumferential grooves, and first and second radial-direction grooves. The plurality of cooling gas holes includes first and second holes. The first hole overlaps the first radial-direction groove. The second hole overlaps the second radial-direction groove. The base plate includes a gas inlet path that supplies the cooling gas to the first and second holes. The first circumferential groove includes first and second end portions. The second circumferential groove includes third and fourth end portions. The third end portion and the fourth end portion do not overlap the first end portion in the radial direction.

Abstract: A sanitary washing device includes a casing, a nozzle, and a nozzle drive unit. The nozzle drive unit advances and retracts the nozzle between a storage position and an advanced position. The nozzle drive unit includes a supporter, a gear, and a cable rack. The supporter includes a rail allowing the nozzle to slide. The gear applies a drive force to advance and retract the nozzle. The cable rack is connected with the nozzle and meshes with the gear. The cable rack includes a nozzle connection part connected with the nozzle. The gear and the cable rack mesh at a meshing part. The meshing part is positioned at a same position in a longitudinal direction as the nozzle connection part or further frontward than the nozzle connection part when the nozzle is at the storage position.

Abstract: Summary Problem: To provide a spout apparatus in which sagging of the mesh structure portion in the flow-conditioning member due to water pressure can be suppressed even if the flow-conditioning member is formed by a fine diameter mesh structure, and the flow-conditioning member can be compactly constituted and flow velocity distribution made uniform.
Solution Means: The embodiment of the invention is a spout apparatus 2, including a spout apparatus main unit 6, a flow-conditioning member 12, and a spray member 16; wherein the flow-conditioning member 12 is formed by a mesh structure in which numerous fine holes are formed, and the mesh structure is layered and formed three dimensionally, such that the mesh structure portion of at least a portion of the mesh structure extends in a direction parallel to the direction of water flowing into the flow-conditioning member.-

Abstract: According to one embodiment, an electrostatic chuck includes a ceramic dielectric substrate, a base plate, and a first porous part. The ceramic dielectric substrate has a first major surface and a second major surface on opposite side from the first major surface. The base plate supports the ceramic dielectric substrate and includes a gas feed channel. The first porous part is provided at a position between the base plate and the first major surface of the ceramic dielectric substrate. The position is opposed to the gas feed channel. The first porous part includes a plurality of sparse portions each including a plurality of pores. The plurality of sparse portions are spaced from each other. Each of the plurality of sparse portions extends in a direction inclined by a prescribed angle with respect to a first direction from the base plate to the ceramic dielectric substrate.

Abstract: A toilet device includes a casing, a lock part, and a release part. The casing is mounted to an upper surface of a toilet. The lock part restricts movement of the casing with respect to the toilet. The release part releases the restriction by the lock part. The release part includes an operation part and a transmission part. The transmission part transmits the operating force applied to the operation part to the lock part. The operation part is located at a position separated upward or downward from a lower end of the casing.
