An extinguisher management system includes a fire extinguisher, a management server and a maintenance server. The fire extinguisher transmits a notification signal when a measured pressure thereof is beyond a predetermined pressure range. The management server includes a wireless receiver for receiving the notification signal from the fire extinguisher, and a database storing an apparatus data set corresponding to the fire extinguisher. The management server outputs an apparatus information in the apparatus data set in response to receipt of the notification signal. The maintenance server is configured to update a to-be-maintained list according to the apparatus information received from the management server.

A structure for fastening sword blade to scabbard includes two magnets having different polarities and imbedded in a blade and a scabbard of a sword, respectively. The magnet imbedded in the blade is flush with an outer surface of the blade near a cross guard of the sword, and the magnet imbedded in the scabbard is flush with an inner surface of the scabbard corresponding to the magnet on the blade. With these arrangements, the sword blade may be easily inserted into and magnetically held to the scabbard without the risk of unexpectedly moving out of the scabbard, and may be smoothly drawn out from the scabbard without the risk of being stuck to the scabbard.

An anti-leakage device includes an insertion rod and a plug unit. The insertion rod has an insertion segment and an exposed segment opposite to the insertion segment. The plug unit includes frustoconical first and second plug members that are mounted on the insertion segment of the insertion rod and made of an elastic material, and that are respectively distal from and proximate to the exposed segment of the insertion rod. Each of the first and second plug members has a small end surface and a large end surface that are opposite to each other. One of the first and second plug members is adapted to be plugged into a hole of a liquid container with the exposed segment of the insertion rod being adapted to be exposed from the liquid container.

A control apparatus having a microprocessor controller for energy conservation and fuel economy includes a liquid container containing a combustion supporting agent; a metering pump having a liquid inlet and a liquid outlet. The liquid inlet communicates with the liquid container; a vaporizer communicating with the liquid outlet of the metering pump; and a microprocessor controller electrically connected to the metering pump. The microprocessor controller controls the flow rate at which the combustion supporting agent is pumped out of the liquid container by the metering pump and the flow rate at which the combustion supporting agent is discharged into the vaporizer by the metering pump. The vaporizer atomizes the combustion supporting agent. The flow rate of the combustion supporting agent is controlled for combustion efficiency.

A system for automatically containing leakage of liquid from a reservoir includes a surrounding wall, a driving unit, a sensor and a controller unit. The driving unit is configured to drive the surrounding wall to move between containing and non-containing positions. The sensor is capable of generating a detection signal. The controller unit receives the detection signal, and determines whether leakage of liquid from the reservoir has occurred. When it is determined that the leakage of liquid from the reservoir has occurred, the driving unit is actuated by the controller unit to drive the surrounding wall to move from the non-containing position to the containing position for containing the leakage of liquid.

A nunchaku includes a joint pin for connecting a baton of the nunchaku to a chain. The joint pin includes a front section for extending through a bearing mounted inside the baton to project from an inner end of the baton to connect to the chain, and a circular flange provided at a rear end of the joint pin to abut against an inner side of the bearing. The flange of the joint pin has an outer diameter larger than an inner bore of the bearing and therefore effectively prevents the whole joint pin and accordingly the chain from separating from the baton even when the steel balls of the bearing are badly worn off and fail to engage with the joint pin.
摘要:
A floor pad module is formed along its four edges with specially designed first and second dovetails and corresponding dovetail grooves, so that the floor pad module could be reversed without affecting its free connection to another floor pad module via engagement of the dovetails with the dovetail grooves. This enables the floor pad module to be manufactured with two different colors shown at a front and a reverse side thereof, and a consumer may connect a plurality of the floor pad modules to form a large area of floor pad showing differently colored patterns simply by reversing some of the floor pad modules in the same one pack without the need of purchasing two or more packs of monochromatic floor pad modules.
