The present invention provides a method that enables the use of an aqueous solution of a copolymer of vinyl alcohol and an alkali metal neutralized product of ethylenically unsaturated carboxylic acid or carboxymethyl cellulose or a salt thereof, as a binder for secondary batteries, without causing a significant viscosity increase even if stored in the state of an aqueous solution. More specifically, the present invention provides a composition in the form of an aqueous solution containing a copolymer of vinyl alcohol and an alkali metal neutralized product of ethylenically unsaturated carboxylic acid and/or carboxymethyl cellulose or a salt thereof, wherein when the viscosity of the composition after being diluted with water (25° C. or less) to a viscosity of 200±100 mPa·s at room temperature (25° C.) and being adjusted to a temperature of 25° C. is defined as X(Pa·s), and the viscosity of the composition after being placed in an airtight container and being allowed to stand at 95° C. for 8 hours is defined as X(Pa·s), the change rate obtained by the following formula:Change rate (%)=()/×100is 0 to 10%.

Polymer composition

A recording device includes a tuner, a memory, and a controller. The tuner receives broadcast programs. The memory records the broadcast programs via a plurality of recording paths between the tuner and the memory. The controller uses at least two of the recording paths to record a plurality of consecutive broadcast programs on a predetermined channel in the memory. An output of the tuner is inputted to the at least two of the recording paths.

Recording device and recording method

The present invention has its object to provide a direct hemoperfusion adsorber packed with an adsorbent made by using a water-insoluble carrier having a relatively readily available particle size distribution, with water-insoluble microparticles having been removed therefrom, without needing any special granulation apparatus or coating apparatus, and method of obtaining a direct hemoperfusion adsorbent having water-insoluble microparticles removed therefrom. Now, a direct hemoperfusion adsorber has been obtained that is packed with an adsorbent having a number average particle diameter of not smaller than 300 &#x3bc;m but not larger than 600 &#x3bc;m, with the coefficient of variance in particle diameter distribution being not lower than 10% but not higher than 20%, and having water-insoluble microparticles removed therefrom to a safe level, without the loss of the adsorbent, by using a water-insoluble microparticle-removing-mesh such that the ratio of the mesh opening size for removing water-insoluble microparticles to the mesh opening size of the adsorber is not lower than 1.3 but not higher than 1.5.
