IPC: A61B5/022
Filed: 2003-05-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide an inflation bulb having a lip structure formed in one-piece with the inflation bulb instead of a conventional gas valve.  <P>SOLUTION: The inflation bulb 200 suitable for a hemodynamometer has a gas inlet end 210 and a gas outlet end 220. An almost flat lip part 212 projects inwardly from the inside of the gas inlet end. The lip part defines a gas inlet opening and the external air enters the inflation bulb from the opening. The gas outlet end has a gas outlet opening which is connected to a gas intake tube. When the inflation bulb is pressurized, the lip part closes the gas inlet opening and the air inside is extruded from the gas outlet opening. When the inflation bulb is relieved from pressure, the inflation bulb returns to its original state and the lip part opens the gas inlet opening. A pressurization belt of the hemodynamometer is inflated by repeating pressurization and relief of the inflation bulb.  <P>COPYRIGHT: (C)2004,JPO

Title: Brewing bag formed from non-woven fabric
Inventor: KISHIGAMI MORIHIRO
IPC: D04H3/005
Filed: 2003-05-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a brewing bag, such as a tea bag, which prevents a substance that degrades the flavor as of tea from entering when the tea is brewed.  <P>SOLUTION: The brewing bag is formed from non-woven fabric. The non-woven fabric is produced by a spun-bond method. The fibers of the non-woven fabric are made of core sheath type composite long fibers that have polyester as a core constituent and polypropylene as a sheath constituent. The core sheath type composite long fibers are bonded by softened or melted polypropylene that is the sheath constituent. Since the non-woven fabric is produced by the spun-bond method, the fabric is free from sticking of fiber oil. In addition, since polypropylene and polyester that have fusing points far higher than the temperature of hot water are used, the constituents are prevented from dissolving in the hot water even when they are immersed in it. Using the brewing bag, serving as a tea bag, which is made of the non-woven fabric, reduces the degree to which fiber oil or polypropylene may be mixed into extract. Accordingly, the flavor of tea or the like is not degraded.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
