    摘要: A water-based thermosetting coating composition comprises a polyester resin having a number of pendant carboxyl groups and a crosslinker for the resin both dispersed in an aqueous medium containing a neutralizing base. The polyester resin contains as polyester-forming polyhydric alcohol reactants from 1 to 40% by weight of the entire polyester-forming reactants of a polyalkadienediol or a hydrogenated products thereof and from 2 to 50% by weight of the entire polyester-forming reactants of a 2,2-bis(hydroxymethyl)alkanoic acid. The coating composition is useful for forming a multilayer coating film on metallic substrates such as automobile bodies by applying the coating composition as an intermediate coating layer between an electrodeposition coating layer and a top coating layer.

    摘要: Provided is a method for reading data from a variable resistance nonvolatile storage element, where the operation for reading data is less susceptible to a fluctuation phenomenon of resistance values in reading the data. The method includes: detecting a current value Iread that flows through the nonvolatile storage element that can be in a low resistance state RL and a high resistance state RH, with application of a fixed voltage; and determining that (i) the nonvolatile storage element is in a high resistance state when the current value Iread detected in the detecting is smaller than a current reference level Iref, and (ii) the nonvolatile storage element is in a low resistance state when the current value Iread detected in the detecting is larger than the reference level Iref, the current reference level Iref being defined by (IRL+IRH)/2
