Abstract: The present invention provides a transparent functional film comprising a transparent plastic substrate film and a hard coat layer provided thereon, wherein functional ultrafine particles are present in a highly localized form, thereby enabling the functional ultrafine particles to effectively exhibit their function and, at the same time, the hard coat layer to have a good adhesion to the functional ultrafine particle layer; and also an antireflection film and processes for producing the transparent functional film and the antireflection film.      A functional ultrafine particle layer 2 is formed on a release film 1. Separately, a resin composition for a hard coat layer is coated on a transparent plastic substrate film 3. The coated release film is laminated by press bonding to the coated transparent plastic substrate film so that the functional ultrafine particle layer 2 faces the resin composition coating, thereby causing part of the functional ultrafine particles 5 to be embedded in the resin composition coating for a hard coat layer. The resultant laminate is cured, and the release film 1 is then peeled off. In the resultant transparent functional film, the functional ultrafine particle layer 2 is partly embedded in and fixed to the hard coat layer 4, and the functional ultrafine particles 5 are localized in the hard coat layer 4 on its surface side.

Title: Control system with collection chamber
Inventor: STRATTAN SCOTT C
IPC: E21B47/09
Filed: 1996-05-07
Abstract: The invention relates to a control system for a subsurface safety valve (SSV). A pressure-balance feature is introduced such that the control system com-ponents are unaffected by the depth of placement of the SSV. Through the use of this feature, the standard hydraulic control system used for surface components can also be used for an SSV regardless of its depth of installation. In another feature of the invention, a shuttle valve is provided so that each time the SSV is stroked, a volume of control fluid is purged into the annulus. One embodiment of the shut-tle valve may or may not be sensitive to annulus pressure and employs annulus pressure as an aid to stroking the shuttle valve upon application of surface control pressure to assist in actuation of the SSV, while at the same time providing for a purge of a controlled volume of fluid.
