A flush toilet of the present invention includes: a bowl including a waste receiving surface, a rim and a shelf surface formed between the waste receiving surface and the rim, the shelf surface of the bowl including linear portions provided 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 from a rim spout port 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 located on an upstream side of the rim spout port has a sloped surface ascending toward the rim spout port.

A flush toilet apparatus includes a toilet body that includes a rim water spout port, a tank that stores washing water, a rim side water supply channel that supplies washing water to the rim water spout port, a tank side water supply channel that supplies washing water to the tank, a flow channel switching part that adjusts an amount of washing water that is supplied to one or both of the rim side water supply channel and the tank side water supply channel, and an electrical power failure detection part that detects electrical power failure, wherein, in a case where electrical power failure is caused when washing water is supplied to the tank side water supply channel, the flow channel switching part decreases washing water that is supplied to the tank side water supply channel and increases washing water that is supplied to the rim side water supply channel.

A toilet assembly includes a toilet, a non-vitreous fluid delivery component, and a connector assembly. The non-vitreous fluid delivery component is coupled to, and in fluid communication with, the toilet. The connector assembly couples the non-vitreous fluid delivery component to the toilet in a substantially watertight manner. The connector assembly includes a connector body, a nut adjustably coupled to the connector body, and a sealing member disposed on the connector body. The nut is configured to be adjusted relative to the connector body to cause the connector body to compress the sealing member against a portion of the toilet, such that the sealing member creates a substantially watertight seal between the toilet and the connector body.

A flush toilet according to an embodiment includes a bowl part, a rim part, and a water spout port. The bowl part receives waste. The rim part is formed on a top of the bowl part. The water spout port spouts a washing water along the rim part. A height of a bottom surface wall that forms a passing water channel where the washing water flows along the rim part increases from an end part on a side of the water spout port toward a front end of the bowl part.

A shower head includes a water input pipe, a fluidic oscillator, and at least one water outlet. The water input pipe is configured to supply a flow of water. The fluidic oscillator includes at least one predetermined geometry to control the flow of water ejected from the fluidic oscillator to include a repeating fan of water at a predetermined angle range. The at least one water outlet is configured to provide the flow water including the repeating pattern of water.

A flush toilet includes a bowl part that receives waste, a drainage water trap that is connected to a bottom of the bowl part, a jet water spout port that spouts washing water toward the drainage water trap, and a discharge port that is connected to the drainage water trap and discharges waste, wherein the drainage water trap includes a rising pipe line that is connected to the bowl part, a curved pipe line that includes a rising curved part that is connected to the rising pipe line and rises backward and a falling curved part that falls backward, a falling pipe line that is connected to the curved pipe line, and a swelled part that forms a space that is swelled toward a back side thereof and is continuous with the discharge port, on a downstream side of a curved top part of the curved pipe line.

In a power converter, each of a positive busbar and a negative busbar includes a first current path that has a first thermal resistance and is a current flow path between a power-source connection terminal and at least one terminal connection portion, and a second current path that has a second thermal resistance and is a current flow path between the power-source connection terminal and an element connection portion. The first thermal resistance of the first current path of at least one of the positive busbar and the negative busbar is lower than the second thermal resistance of the second current path of the at least one of the positive busbar and the negative busbar.
