A water diverting device is used for fitting inside a porous surrounding wall of a vertical drainage pipe which is deeply inserted into the soil for collecting water from the ground level. The water diverting device includes a tubular wall having at least one slit, and a base wall having at least one drainage port. The drainage port is located at a higher level than a lower slit edge of the slit so as to have a lower level of water accumulated for passing through the slit and an upper open end segment of the porous surrounding wall, thereby soaking the soil near the ground level.

A hand tool that is capable of efficiently, inexpensively, and quickly attaching to a pipe and allows for boring an access hole to be used for accessing the inside of the pipe and unclogging the pipe.

An access port member includes: a body 8 to be connected to a predetermined portion of a blood circuit for causing a patient's blood to extracorporeally circulate, the body 8 internally including a flow path 8b for circulating the blood and having an opening 8c communicating with the flow path 8b; a valve 9 that is made of an elastic member covering the opening 8c and attached to an attachment part 8d of the body 8, the valve including a slit that makes a transition from a closed state to an open state when pressed by a tip 11a of a syringe 11 capable of collecting blood or injecting a drug; a cap part 10 fixed to the body 8 with the valve portion 9 interposed therebetween and the slit 9a facing outward; and a rib 9b formed integrally along the periphery of the slit 9a in the valve 9.

A threaded connection body is welded to the wall of a pipe, seachest or other flooded cavity within the hull of a ship or floating offshore installation. A sealed cutting apparatus is mounted via a valve unit n the connection body and a cutter extended through the open valve to form an opening in the wall. After retracting the cutter and closing the valve, the cutting apparatus is replaced by an inspection unit having a camera which is extended through the valve and the opening to inspect the cavity. After retracting the camera and closing the valve, the inspection unit is replaced by a plug deployment unit which advances a plug through the valve and screws it into the connection body. The valve unit can then be removed and replaced with a cap so that the plug and the cap provide a double seal to the connection body.

To provide a depressurizer with a function of depressurizing a filling hose separated from a filling device when a safety device (safety joint) operates (separates). A depressurizers (10, 11) according to the present invention are mounted to a filling hose (21) for filling hydrogen from a hydrogen filling apparatus (100) to a vehicle. In the present invention, it is preferable that on a main body portion (1) of the depressurizers (10, 11) is formed a depressurizing communication hole (1B) communicating with a hydrogen gas passage (1A); a plug (2) that can be inserted into the depressurizing communication hole (1B) is mounted; and on the depressurizing communication hole (1B) and the plug (2) are formed tapered portions (a pin tapered portion 2B of the plug 2 and a tapered portion 1BB of the depressurizing communication hole 1B) with complementary shapes.
