Sealing ring for pipe coupling

According to one embodiment, an inverter apparatus includes a power conversion unit, a wireless communication unit and a control unit. The power conversion unit converts input power that is one of DC power and AC power into AC output power. The wireless communication unit wirelessly receives a first synchronization signal. The control unit controls a phase of the output power based on the first synchronization signal.

Inverter apparatus and inverter system

According to one embodiment, a wireless communication apparatus includes a management unit and a setting unit. The setting unit sets, upon determination of disconnection of a wireless link with a base station of a main network used for communication, duration for waiting for receiving a first signal related to formation of a new network based on a priority. The management unit, when the duration is set, waits for receiving the first signal until the duration elapses. The setting unit switches an operation mode to a base station mode if the first signal is not received even the duration elapses. The management unit repeatedly performs a process to transmit the first signal after the operation mode is switched to the base station mode.

Wireless communication apparatus

A pipe coupling apparatus for simultaneously connecting and locking together pipe couplings comprising a plurality of sockets and plugs. The pipe coupling apparatus includes a socket-side unit having a plurality of sockets and a plug-side unit having a plurality of plugs. Each socket is provided with locking elements, and each plug is provided with an engagement groove. When the plug is inserted into the socket, the locking elements enter the engagement groove. A sleeve is provided displaceably between a locking completion position where it holds the locking elements from coming out of the engagement groove to lock the socket and the plug to each other and a retracted position separated from the locking completion position. A locking confirmation plate is displaceable from a locking unconfirmed position to a locking confirmed position when all the sleeves are at the locking completion position, thereby allowing confirmation of the completion of locking.

Pipe coupling apparatus

A male coupling member is configured such that, even if a front end surface of a valve member is hit with a hammer, the valve member cannot bite into an opening surface of a coupling body. The male coupling member has a coupling body, a valve member, and a spring member. The valve member has a front end portion fitted into a front end opening of the coupling body, and a valve body. The front end portion has a circular front end surface, a front end annular surface having a smaller diameter than an opening surface of the coupling body, and a reduced-diameter surface having a smaller diameter than the front end annular surface. The reduced-diameter surface is configured such that when the valve member is tilted and, consequently, the reduced-diameter surface engages a rear end edge of the opening surface, the length b from the point of engagement between the reduced-diameter surface and the rear end edge to the outer peripheral edge of the front end surface of the valve member through the axis of the valve member is not larger than the diameter a of the front end surface.

A coupling member is disclosed which includes a valve device that is axially movable between an open position and a closed position where the valve device closes an annular valve opening defined an outer valve seat portion and an inner valve seat portion. The valve device includes an outer annular sealing member and an inner annular sealing member. The inner annular sealing member includes an annular extending portion configured such that, when the valve device approaches the closed position, the annular extending portion sealingly engages the inner valve seat portion and is elastically bent to allow the valve device advance further to the closed position so that the outer annular sealing member positively engages the outer valve seat portion.

Coupling member for pipe coupling

A coupling according to the present invention has a socket () and a plug () that is inserted into and connected to the socket. The socket includes a socket body () having a first through-hole () for a plug-locking element () and an elongated second through-hole () for a sleeve-actuating element (), and a sleeve () set around the socket body. The sleeve is urged by a spring member () toward a position for pressing the plug-locking element () against a locking recess () of the plug to prevent the plug from slipping out of the socket. The sleeve has a locking surface () that presses the plug-locking element in the position described above. When being inserted into the socket, the plug engages with the sleeve-actuating element to move the sleeve rearward, thereby disengaging the locking surface from the plug-locking element.

Coupling, and socket and plug for use in the coupling

A coupling member is provided that comprises a valve movable between a closed position and an opening position. The valve is provided with a seal ring fixed in an annular groove formed in the valve and urged against a valve seat in the closed position. The groove has a forward annular groove portion and a rear annular groove portion shallower than the forward annular groove portion. The seal ring has forward and rear annular seal portions fitted in the forward and rear annular groove portions, respectively. The rear ring portion has substantially the same diameter as the forward seal portion.
