Abstract: Provided is a granular activated carbon which has a filtered flow rate of a predetermined value or higher, and a high water purification performance; and a method for manufacturing the same. A granular activated carbon comprises a plurality of activated carbon granules and a binder for binding the plurality of activated carbon granules, wherein the binder is composed of net-like fibers. Also, a method for manufacturing the granular activated carbon includes a step for spraying and drying slurry which is obtained by dispersing the activated carbon granules and the fibers in water.

Abstract: Provided is a toilet remote controller for remotely operating a toilet device. The toilet remote controller includes a remote controller main body. The remote controller main body includes a first operation unit, a case, and a cover panel. The case forms a storage space for storing an electrical component. The cover panel is provided at a position corresponding to the first operation unit and covers the case with light permeability.

Abstract: Provided is a toilet device which includes a toilet body including a toilet bowl part, and an analysis device that includes an optical member in contact with urine introduced into the toilet bowl part and that is capable of analyzing a constituent of the urine by detecting analysis light propagated within the optical member and totally reflecting off a urine contact surface of the optical member. An optical path for the analysis light is set such that the analysis light totally reflects off the urine contact surface of the optical member multiple times through multiple reflection. This can increase the number of times the analysis light reflects off the urine contact surface against urine.

Abstract: A hot water supply system includes a water supply pipe for supplying cold water, a hot water supply pipe for supplying hot water heated by a hot water supply device, a drain pipe for draining waste water, a heat exchange device for heating cold water supplied from the water supply pipe using the waste water, and a flow rate control mechanism for controlling, when supplying warm water obtained by mixing cold water heated by the heat exchange device and hot water heated by the hot water supply device, the flow rate of the cold water and the flow rate of the hot water so as to maintain the temperature of the warm water.

Abstract: An operating device includes a device main body, and an operating body operated by a user. The operating body is movable between a first position and a second position and enables activation of a water-related appliance by moving from the first position to the second position. The device main body includes a marker part that is different in outer surface color from a neighboring area of the device main body. When the operating body is placed at the first position, the operating body hides the marker part from the outside, and, when the operating body is placed at the second position, the operating body exposes at least part of the marker part to the outside.

Abstract: Provided are valve devices that can be formed compactly. A valve device includes a primary-side valve element including a planar part and a secondary-side valve element connected to the primary-side valve element to be slidable to the planar part of the primary-side valve element, in which a water discharge state can be switched by sliding the primary-side valve element or the secondary-side valve element. The secondary-side valve element includes a packing member that contacts the planar part of the primary-side valve element. The primary-side valve element can include a disk member including the planar part, and the disk member is made from metal.

Abstract: A toilet system having a toilet device with a toilet seat and electricity-using equipment such as an electronic component unit; a power supplying device that is disposed behind a wall and that has a power supply coil by which power is supplied; and a power receiving device that has a power receiving coil built into the toilet seat, that has a resonance frequency with respect to the power supplying device set, and that supplies power received from the power supplying device by way of magnetic resonance to the electricity-using equipment such as the electronic component unit.

Abstract: A faucet device includes a hot water/water mixing valve, a water purification cartridge, a primary side flow path that supplies water to the hot water/water mixing valve and the water purification cartridge, and a secondary side flow path that discharges mixed water flowing out from the hot water/water mixing valve and purified water flowing out from the water purification cartridge to a water discharge port. The primary side flow path and the secondary side flow path are disposed between the hot water/water mixing valve and the water purification cartridge.

Abstract: Provided is a gasket capable of reducing the risk of water leakage from a sealing member for use to join a ceramic member. The gasket is made of elastic material and usable for joining two members which form a flow passage for liquid, and at least one of which is a ceramic member. The gasket includes: a base having a loop shape; a protrusion standing on the base, extending along the loop shape, and protruding toward one of the members; and a retainer formed on an inner periphery of the base and protruding from the inner periphery in an inward direction with respect to the loop shape.
