The present application is directed to use of a thioether compound, obtainable from a first educt that comprises at least two thiol groups and from a second educt that comprises at least one \u03b1,\u03b2-unsaturated amide group as well as at least one tertiary amine group, for the hardening of reactive resins. The interrupt controller is preferably implemented in hardware and its operation is transparent to the processor. The steel strip produced by the method may have a per unit area density of at least about 120 oxide inclusions per square millimeter to a depth of about 2 microns from the strip surface. For example, the memory device can include an ECC control register that stores control information to selectively enable and disable error detection and correction for write accesses. Provided is a packaging box from which a stored article can be easily taken out when a lid plate is opened, and which can endure a compressive stress imposed when a multiple number of the boxes are piled up.
