Title: Polymeric toner
Inventor: TAGAWA REIKO
IPC: G03G9/087
Filed: 1987-11-24
Abstract: PURPOSE:To obtain a toner having retarded coagulating property and high fluidity by reducing surface energy of the toner by incorporating trifluoroethyl acrylate as a polymerizable monomer component into the toner. CONSTITUTION:In a polymeric toner obtd. by suspending a polymerizable monomer system in aq. phase, 2-15wt.% (basing on the total amt. of monomers) trifluoroethyl acrylate is incorporated as a polymerizable monomer component into the polymerizable monomer system. If the content of trifluoroethyl acrylate exceeds 15wt.%, thermal characteristics such as blocking property of obtd. toner is insufficient due to lowering of glass transition point. On the other hand, if the content is <2wt.%, inferior toner having high coagulating property and insufficient fluidity is obtd. due to insufficient effect of trifluoroethyl acrylate. By this constitution, the surface energy of the toner is reduced by the effect of F in the component, and a toner having low coagulating property and high fluidity is obtd.

Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a surface treated steel tube for hydraulic bulge working capable of drastically shortening the process by eliminating the degreasing and cleaning and the coating and drying process of a tube stock by forming an organic resin film for liubrovation having the thickness of 1-100μm on the external surface of the steel tube. SOLUTION: The organic resin film for lubrication of 1-100μm is formed on at least the external surface of a steel tube. The organic resin such as acrylic resin or polyester is used. When the film is too thin, flaws and seizure are liable to cause during the bulge working, and the minimum film thickness of 1μm is necessary. When the film thickness exceeds 100μm, the film is liable to be peeled due to the internal stress in the film, and the peeled film is deposited and accumulated on a die surface to cause press-fit flows. The film thickness is preferably 10-50μm. The seizure between the die and the material during the hydraulic bulge working can be prevented, and defective phenomena such as buckling and breakage can be suppressed.

IPC: F16K3/12
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To improve water cutoff capability of a gate valve and reduce its size and weight to reduce cost. SOLUTION: A valve body 2 is bent at a bent part k by a pressing force given downward by a valve stem 3, and acts so that it continuously presses a pressing seal surface 2b against a valve seat 1b at a proper force.

Also a wedge seal surface 2a is formed only one surface of the valve body 2, and the installation part 2d of the valve body 2 is provided on the other surface of it at the seal surface 2a part. As a result, the valve body 2 can be reduced in size and thus the gate valve can be reduced in size and weight.  In addition, because the installation part 2d is located inside a fluid path 1c when the valve body 2 is closed and open to the other side, hands and tools are accessible to the fluid path 1c so as to fix the valve body 2 to the valve stem 3 with a fixture 4 or the fixture 4 can be removed so as to separate the valve body 3 from the valve stem 4. Thus the assembly and disassembly of the gate valve can be performed easily.
