Abstract: The present invention relates to acrylonitrile compounds of formula (1): [wherein, R is a C1-C6 alkyl, a C3-C7 cycloalkyl optionally substituted by a C1-C4 alkyl, a naphthyl, etc., R1 is H, a halogen, a C1-C6 alkyl, etc., A is specific 5-membered aromatic heterocyclic ring containing two hetero atoms selected from N, O and S, etc., B is H, a C1-C4 alkyl, a C2-C4 alkoxyalkyl, etc.] Said compounds are useful as agricultural chemicals, in particular insecticides and acaricides.

Abstract: This invention is to provide a travel time information arithmetic operation method and apparatus for calculating travel time information using data obtained by a toll collection system. The travel time information arithmetic operation apparatus includes a travel time arithmetic operation section for calculating a travel time (time required by a vehicle to travel from a given point to another given point) of a vehicle on the basis of data obtained by the toll collection system installed on a tollroad and representing the entry point, entry time, exit point, exit time, and model of the vehicle, and date, a tollgate data storage section for storing the data obtained by the toll collection system and travel time data obtained by the travel time arithmetic operation section, and a travel time information arithmetic operation section for calculating an average travel time value using the travel time n-minutes accumulated data stored in the tollgate data storage section and generating travel time information.
