Abstract: Provided is a flush toilet device in which flushing can be effectively performed with small amount of flush water by accurately setting opening times for individual drain valves. A flush toilet device (1) of the present invention includes a flush toilet main body (2), a flush water tank (4), a first drain valve (10) configured to control flush water from a rim spout port (2d) by opening and closing a first drain port (4b) provided in the flush water tank, a second drain valve (12) configured to control flush water from a jet spout port (2e) by opening and closing a second drain port (4c) provided in the flush water tank, and a hydraulic drive mechanism (16) configured to open the first or second drain valve by using water supply pressure of flush water supplied from a tap water supply line to the flush water tank.

Abstract: The present invention provides a flush water tank device including an outer tank, an inner tank disposed inside the outer tank, a water supply valve, a first water discharge/stop switching mechanism disposed inside the outer tank and outside the inner tank to switch supply and stop of flush water stored in the outer tank to the flush toilet main body, and a second water discharge/stop switching mechanism disposed inside the inner tank to switch supply and stop of flush water stored in the inner tank to the flush toilet main body, the water supply valve is configured to supply flush water into the inner tank, and the flush water supplied into the inner tank overflows from two or more sides of the inner tank to flow into the outer tank.

Abstract: The present invention provides a flush water tank device, including a flush water tank main body including a first tank part and a second tank part for storing flush water, a rim spouting switch mechanism that switches discharge and stop of flush water in the first tank part, and a jet spouting discharge valve that switches discharge and stop of flush water in the second tank part, the first tank part and the second tank part are configured to have different cross-sectional areas depending on a height, and a ratio of the cross-sectional area of the first tank part to that of the second tank part at a first height is different from a ratio of the cross-sectional area at a second height that is lower than the first height.

Abstract: 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.

Abstract: A water supply mechanism includes a switching part that executes switching between water supply and water shut-off, a manual operation valve on the switching part that is capable of a manual operation thereof, and a pushing member that pushes the manual operation valve to provide a valve-closed state. The manual operation valve is pulled in a direction opposite to a pushing direction of the pushing member to provide a valve-opened state. The manual operation valve includes a plunger, an external cylinder member that encloses the plunger, a first engaging point in the external cylinder member, and a fixation part in the external cylinder member that fixes the plunger in the valve-closed state or the valve-opened state. The plunger moves beyond the first engaging point as the manual operation valve is pulled, and is fixed in the valve-opened state as a pull of the manual operation valve is released.

Abstract: In a communication system pursuant to the frame relay (FR) architecture, to prevent disability of a data transmission due to the discarding of LMI data. When receiving FR frames from an FR terminal 16, a multiplexer 14-2 separates LMI frames stored with LMI data from user frames stored with user frames, based on values of DLCI address fields, and queues them separately. The multiplexer 14-2 sends all of the queued LMI frames via the data transmission path 18 in a preferential manner and, then, it sends a portion of the queued user frames that is transmissible by a remaining portion of the transmission capacity to the data transmission path 18, thereby causing the user frames alone to be subjected to shaping processing.
