摘要： Provided is a faucet fixture to which antifouling functionality is imparted without causing localized corrosion. The present invention is a faucet fixture comprising a metal base material and a plating layer partially formed on the surface of the metal base material. The metal base material contains at least one metal element species selected from the group consisting of copper, zinc, and tin. The plating layer contains at least one metal element species selected from the group consisting of chromium and nickel. An organic layer is further provided on the plating layer, with a passive layer present on the surface of the plating layer being interposed therebetween. The organic layer is bonded to the passive layer via the bonding of a metal element (M), which constitutes the passive layer, and a phosphorus atom (P) in at least one type of group (X) selected from the group consisting of phosphonate groups, phosphate groups, and phosphinate groups, with an oxygen atom (O) interposed therebetween (M-O—P bond). Group X is bonded to a group R (wherein R is a hydrocarbon group, or a group comprising an atom other than carbon at one or two locations within a hydrocarbon group). The phosphorus atom concentration in the portion of the surface of the metal base material on which the plating layer is not formed is lower than the phosphorus atom concentration in the organic layer provided on the plating layer.

摘要： An electrostatic chuck includes: an electrically-conductive base plate including a first part, a second part at an outer circumference of the first part, and a gas inlet path for introducing a cooling gas; a first electrostatic chuck part configured to clamp a wafer on the first part, including a ceramic dielectric substrate that includes an embedded first clamping electrode and at least one through-hole communicating with the gas inlet path; and a second electrostatic chuck part configured to clamp a focus ring on the second part, including a ceramic layer that includes at least one through-hole for introducing a cooling gas and that includes at least a first layer contacting the focus ring when the second electrostatic chuck part clamps the focus ring, in which the first layer is less dense than the ceramic dielectric substrate. Thereby, the electrostatic chuck can increase the device yield.

摘要： According to the embodiment, a sanitary washing device includes a nozzle, a casing, an illuminator, and a controller. The nozzle discharges water toward a private part of a user in a state of the nozzle is advanced into a toilet. The casing includes a nozzle storage part configured to store an entirety of the nozzle in a state of the nozzle is retracted. The illuminator irradiates sterilizing light into the nozzle storage part. The sterilizing light has a sterilizing action. The controller controls the illuminator. The controller includes a first irradiation mode of causing sterilizing light irradiated from the illuminator to be irradiated toward an outer circumferential surface of the nozzle. The controller includes a second irradiation mode of causing sterilizing light irradiated from the same illuminator as the first irradiation mode to be irradiated toward an inner wall of the nozzle storage part.
