Abstract: A flush toilet includes a toilet main body and a tank device. The tank device includes a water supply unit a storage tank, a pump, and a suction pipe. The water supply unit is configured to supply the flush water the storage tank while the pump is being driven. The storage tank includes a large tank section that includes a lowest bottom surface of the storage tank and that is a large-capacity side, and a small tank section that is a small-capacity side. The storage tank main body includes a water supply port on an upper surface of the storage tank. The water supply unit is configured to supply the flush water to the storage tank through the water supply port. The water supply port of the storage tank and an upstream-end opening of the suction pipe are both provided on a large tank section side.

Abstract: According to the embodiment, a toilet device includes a detector and a controller. The detector is detecting whether or not flush water is at a position lower than a full level and higher than a seal level at a surface of a bowl of a flush toilet. The controller is determining a clog state of the flush toilet based on a detection result of the detector after a flush water supplier is closed. The flush water supplier is located in a flow channel discharging flush water into the bowl. The position of the detection region of the detector at the surface of the bowl is separated from flush water flowing in a vertical direction from a water discharge port of the flow channel toward a bottom portion of the bowl after the flush water supplier is closed.

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 faucet apparatus which is capable of, even when a first spouting mode is adapted to be executed when a detection sensor detects an object, causing function water that has an antibacterial effect or bacteria removing effect to be spouted to a detected object without causing tap water by the first spouting mode to be spouted, so that the antibacterial effect or bacteria removing effect can be caused to effectively work on the object. A controller of the faucet apparatus of the present disclosure comprises the first spouting mode and a second spouting mode, and the controller is further provided with a second spouting mode prioritization function of, even if the detection sensor is into a detection state, performing control not to execute the first spouting mode while the second water mode is executed.

Abstract: A flush toilet of the present invention includes: a bowl including a waste receiving surface, a rim and a shelf surface, the shelf surface of the bowl including linear portions formed on a right side and a left side, a front arc portion connected to front ends of the linear portions, and a rear arc portion connected to rear ends of the linear portions; a rim spout portion spouting flush water to the shelf surface to form a circulating flow; and the like. Flush water is spouted backward from the rim spout port along the linear portions of the shelf surface; and the shelf surface and the waste receiving surface are coupled by an inner coupling portion, and a curvature radius of the inner coupling portion along a vertical direction is set to a smaller value on a rear end of the bowl than on a front end thereof.

Abstract: The present invention is a water spouting apparatus (1) that discharges water with reciprocal motion, and has a water spouting apparatus body (10) and a oscillation generating element (22). The oscillation generating element includes a water supply conduit (24), a collision part (30) that generates a vortex on the downstream side, a vortex street conduit (26) provided downstream of the water supply conduit, and a discharge conduit that discharges water guided by the vortex street conduit. The vortex street conduit is configured by connecting the upstream member (18) on which the upstream side is formed and the downstream member (20) on which the downstream side is formed. At the connection between the upstream and downstream members, the height of the vortex street at the upstream end of the downstream member (H2) is higher than the height (H1) of the vortex street at the downstream end of the upstream member.

Abstract: 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.

Abstract: A flush water tank apparatus enabling accurately setting an amount of flush water to be discharged while opening a discharge valve via a discharge valve hydraulic drive unit and a flush toilet apparatus including the flush water tank are provided. A flush water tank apparatus includes a first float device; a second float device that prevents from descent of the discharge valve according to the water level so as to discharge a second amount of flush water; and an adjustment mechanism configured so that when the second amount of flush water is selected by the flush water amount selection portion the clutch mechanism is disconnected at a pull-up height of the discharge valve such that the discharge valve descended by the disconnection of the clutch mechanism is held by the second float device in a holding state.
