Abstract: Fuel gas or some other kind of fluid is stored in a collapsible metallic bag that is attached to a valve and is stored inside a rigid outer container. Between the rigid outer container and the collapsible bag is a space or volume filled with compression gas during use which puts a collapsing pressure evenly upon the bag. In order to reduce bag failures, the outer surface of the collapsible bag has a series of projected streak portions that project outwardly from the vertical length of the collapsing in several locations that prevent the bag from expanding to fill the entire space between the rigid outer container and the bag. These projected streaks form recessed portions in the bag's surface which facilitates the bag collapsing in those predetermined locations evenly which in turn reduces the collapsible bag's failure rate from breaking during operation.

Abstract: A driving piston 4 is provided slidably up and down in a driving cylinder 3 arranged in a tool body 1. By moving a movable sleeve 10 provided at the upper portion of the driving cylinder 3 up and down, the movable sleeve 10 is brought into contact with and separated from the driving cylinder 3 and a cylinder head 8 provided above the driving cylinder 3, whereby a combustion chamber can be opened and closed. Mixture gas obtained by stirring and mixing combustible gas and air together in the combustion chamber by a fan 16 is ignited by an ignition plug 15 disposed at the cylinder head 8 and explosively combusted. By this high-pressure combustion gas, the driving piston 4 is impulsively driven, and a driver 5 coupled to the lower surface side of the driving piston drives nails.

Abstract: This is a portable toilet device. Broken excrement may be certainly drained. Means (40) for breaking the excrement having crushing blades is installed in the stagnant portion (18) of the body (20) of the toilet device, means (200) for sending the broken excrement by compression, which sends compressed air into the stagnant portion (18), and a lid for open and closure that closes the stagnant portion (18) tightly are provided. When treating the excrement after bowel movement, the lid for open and closure is closed and then, by driving the means for breaking the excrement, the excrement is stirred and broken into fragments with the stagnant portion being tightly closed. After breaking the excrement into fragments, compressed air is jetted into the stagnant portion so that a liquid mixture formed by breaking the excrement into fragments can be sent by compression toward a side of drain hose (14).

Abstract: The invention provides an apparatus for outputting compressed air in a compressor to a plurality of pneumatic tools at a plurality of pressures. The apparatus includes: an air tank storing compressed air compressed by the compressor at a high pressure; a pressure adjusting portion connected to said air tank and adjusting a pressure value of the compressed air in a region from the high pressure to zero; a pressure outputting portion connected to a secondary side of said pressure adjusting portion and outputting the adjusted compressed air to at least one of a first pneumatic tool driven at a first pressure and a second pneumatic tool driven at a second pressure. The first pressure is larger than the second pressure, and the adjusted compressed air is not output to the second pneumatic tool at the first pressure.
