A collar having a divided structure and surrounding a fitting connection part between a spigot portion and a socket portion in a sealed state is externally mounted over both pipe portions. A first disengagement blocking part that blocks, by contact, a relative disengagement movement beyond a certain level between the socket portion and the collar is provided at a location where the collar and the socket portion side face each other. A second disengagement blocking part provided with a retaining part in which falling-off resistance between the retaining part and an outer peripheral surface of the spigot portion increases according to a disengagement movement of the spigot portion is provided on a pipe support portion side on one end side in a pipe axis direction of the collar.

An extendable and contractible flexible joint having a pair of flexible joint portions, which are bendable and fitted and connected to a connection sleeve, in a direction of a pipe axial line. An extending motion limiting portion includes a fluid chamber into which a portion of a pressure fluid in a flow path diverges and flows, and is configured to apply a fluid pressure applied to pressure receiving surfaces of the fluid chamber. An inner joint body of each of both the flexible joint portions is configured to be attachable and detachable to and from the connection sleeve, and an outer joint body and the inner joint body of each of both the flexible joint portions are configured to be attachable and detachable to and from each other.

Extendable and contractible flexible joint

A video receiving apparatus includes a receiver, a first display, an extractor, an information forming controller, a number-of-viewer detector, a communicator, and a display controller, leading to appropriate display of configuration information and associated information of a video content. The extractor extracts a partial content from the video content. The information forming controller forms the configuration information from the partial content. The number-of-viewer detector detects the number of viewers present within a predetermined area. The communicator receives an identifier transmitted from a mobile terminal having a second display. The display controller can selectively display the configuration information on the second display of the mobile terminal identified by the identifier, and displays the configuration information on at least one of the first and second displays based on the number of the viewers and the number of the identifiers.

A driving device that drives a display device using a subfield driving method eliminates the need to use an expensive 1-frame delay memory. A compensated sustain pulse data generator enables displaying the same frame information on the display panel even when the 1-frame delay memory is eliminated. The drive data is generated so that the data that is delayed one frame and is included in the data output from the subfield processing unit and the data that is delayed one frame and is included in the data output from the compensated sustain pulse data generator are mutually cancelling.

A pipe joint construction comprising an elastic seal member () for hermetically sealing between an inner circumferential surface of a receiving pipe section () and an outer circumferential surface of an inserted pipe section () inserted into and connected to the receiving pipe section in a pipe axis direction (X), and a lock member () provided in the inner circumferential surface of the receiving pipe section () adjacent a receiving opening thereof for preventing separation of the pipe sections by contacting an engaging projection () protruding from the outer circumferential surface of the inserted pipe section () in the pipe axis direction, wherein the construction further comprises an attachment/detachment control device (A) for attaching and detaching the lock member () to/from the receiving pipe section () by rotating the lock member () about the pipe axis direction (X) relative to the receiving pipe section () and by moving, in the pipe axis direction (X), the lock member () placed in a specific position in a passage of rotation.

Pipe joint construction

A sluicing valve device in which a valve element is arranged in case members attachable to a pipe, and the valve element comprises a valve element core metal fitting, an elastic seal member covering the same, and a lifting and lowering shaft formed into a rod shape along an insertion direction in order to move the valve element core metal fitting along the insertion direction inside of the pipe, wherein the valve element core metal fitting supports the elastic seal member inserted into the pipe and presses the same from the insertion direction to deform elastically, and a guide portion preventing the elastic seal member from protruding in an axial center direction of the pipe is formed on a tip end side in the insertion direction.
