A solution for soft, hydrogel contact lenses includes a polyether that is controllably released into an eye's tear film when the lens is worn. Polyether components of the subject solution are released from the soft contact lens material matrix over long time periods to produce longer lasting wetting performance, improved lubricity, improved comfort, and / or reduced feeling of dryness from wearing contact lenses. The solution further includes a cationic polyelectrolyte.

A vacuum heat insulation material has a covering material which is a lamination body including a sealant layer, a metal foil layer, a first plastic film layer, and a second plastic film layer which are laminated in this order from inside to outside via adhesive layers. When a foreign body is pierced into the vacuum heat insulation material, the propagation of breakage caused by the piercing is blocked somewhere inside the lamination body, thereby preventing the formation of through-pinholes. This results in the provision of a high-quality vacuum heat insulation material with excellent long-term insulation performance by using a covering material excellent in gas barrier properties and pinhole resistance to the piercing of minute foreign bodies.

An alkaline storage battery in which an actual reaction area is not reduced after increasing a reaction area is provided. A hydrogen storage alloy negative electrode 11 of an alkaline storage battery 10 of the present invention is formed in a strip form including a long axis and a short axis, in which the ratio (A / B) of a length A (cm) of the long axis to a length B (cm) of the short axis is 20 or more and 30 or less (20≦A / B≦30), and the ratio (X / Y) of an electrolyte volume X (g) retained in the hydrogen storage alloy negative electrode 11 to an electrolyte volume Y (g) retained in a separator 13 is 0.8 or more and 1.1 or less (0.8≦X / Y≦1.1). With this arrangement, an alkaline storage battery with high output characteristics and long-term durability performance is obtained.

Deposition of a metal-containing reagent solution or suspension or a carbon nanotube-containing suspension onto a conductive substrate by various pad-printing techniques is described. In the case of a metal-containing solution or suspension, a pseudocapacitive oxide coating, nitride coating, carbon nitride coating, carbide coating, or carbon nanotube coating results. In any event, the active coating has acceptable surface area for incorporation into an electrolytic capacitor, such as one having a tantalum anode.

The invention discloses stereoscopic meshed knitted fabric with unidirectional moisture guide function and a production method thereof. An inner hydrophobic layer is in a polypropylene yarn plain structure. An outer absorbent layer is in a cross-sectional polypropylene stereoscopic drop-needle mesh structure. A middle moisture guide connecting layer is made of polypropylene yarns. The fabric is woven with a double knit machine; rib needle setting is adopted; needles are dropped from lower needle cylinders at intervals of single needles; every six paths form a repeat; the second and the fifth are polypropylene yarns, two needle rows form loops on a needle plate, a single needle row on the needle cylinders is used for weaving rise yarns, and the inner plain structure is woven; the first and the fourth are polypropylene yarns, one of every two needle rows on the needle plate perform tucking, the single needle row on the needle cylinder form loops, and the middle layer is woven; the third and the sixth are cross-sectional polyester yarns, two needle rows on the needle plate are used for weaving rise yarns, the single needle row on the need cylinders form loops, the needles are dropped from the lower need cylinders at intervals of single needles, and the outer stereoscopic drop-needle mesh structure is woven. The fabric is capable of guiding sweat from the inner layer of the fabric to the outer layer thereof fast, the sweat is spread and vaporized from the surface of the fabric, and when the outer layer of the fabric contacts water, the water can be avoided entering the inner layer of the fabric.

There is provided a cleaning device for an image-forming device configured so as to be capable of preventing the image quality from deteriorating by being able to prevent the deterioration of the charging state caused by deposits of foreign matter without increasing costs. There is also provided a cleaning member that can make contact with the cleaning target-members. The cleaning member has a portion composed of melamine resin foam for making contact with at least the cleaning target members, and the melamine resin foam has an Asker F hardness of 5 to 25 points and a hardness variation of 5 points or less, and is used on the cleaning target members in a state obtained by heat compression from the original shape. The pressing member is furthermore disposed in contact with the cleaning member.

The present invention is directed to an ophthalmic solution for soft contact lenses for controlled release of polyethers into an eye's tear film. Polyether components of the subject solution are released from the soft contact lens material matrix over long time periods to produce longer lasting wetting performance, improved lubricity, improved end-of-the-day comfort and reduced feeling of dryness from wearing contact lenses. The present invention also includes the use of cationic polyelectrolytes for controlling the swelling of hydrogel contact lenses typically caused by the absorption of high concentrations of polyethers.

Performance of a fuel cell stack (12) is recovered following long term decay by connecting (51) an auxiliary load (50) to the fuel cell while shutting off one or more of oxidant inlet valve (27a), oxidant pressure regulating valve (28a) or oxidant pump (26), which all may be achieved with a controller (46), to cyclically starve the cathode of oxidant so that it achieves hydrogen potential, e.g., less than 0.1 volts, for on the order of tens of seconds, repetitively, such as at every 10 or 20 seconds, while the auxiliary load remains connected, initially drawing 10 to 100 mASC, for example. Complete rejuvenation is obtained following 1800 or more cycles over a period of five or more hours.

A high surface area catalyst with a mesoporous support structure and a thin conformal coating over the surface of the support structure. The high surface area catalyst support is adapted for carrying out a reaction in a reaction environment where the thin conformal coating protects the support structure within the reaction environment. In various embodiments, the support structure is a mesoporous silica catalytic support and the thin conformal coating comprises a layer of metal oxide resistant to the reaction environment which may be a hydrothermal environment.
