Abstract: A navigation server rapidly generating guide support information in view of a traffic state after occurrence of an accidental situation in a road section, and make a navigation device recognize the same. After occurrence of the accidental situation in a target road section, a changing pattern g2(t) of a cumulative traffic volume CQ of a second position x2 during a first period is estimated, on the basis of a value of a traffic volume Q1 of the target road section at the first time t1. Further, a primary guide support information during the first period is generated on the basis of a standard changing pattern g1(t) of the cumulative traffic volume CQ of the first position x1 and a changing pattern g2(t) of the cumulative traffic volume CQ of the second position x2 as the estimation result.

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.

Abstract: A method for protection of a plant from damage caused by an insect pest of the order Lepidoptera and Diptera is disclosed. An insect controlling agent having an active component of an insecticidal crystal toxin produced by Bacillus thuringiensis var. kurstaki No. 145 FERM BP-3905, No. 161 FERM BP-3906, and No. 116 FERM BP-3907 is used in the method for protection of a plant. The insecticidal crystal toxin has a set of molecular weights as determined by 10% SDS-polyacrylamide gel electrophoresis of 125,000 daltons and 60,000 daltons when produced by No. 145, 130,000 daltons and 60,000 daltons when produced by No. 161, and 130,000 daltons and 60,000 daltons when produced by No. 116.

Abstract: The present invention relates to the compound A of the formula (A), the related compound B, carboxylic acid derived from acid anhydride group of these compounds and esters and salts thereof, microorganisms for producing the compounds, methods for producing the compounds A and/or B by using the microorganisms, and a treated or untreated fermentation broth obtained by culturing strains belonging to genus Zopfiella or Zopfiella curvata No. 37-3 strain. ##STR1## The present invention provides the compounds A and B, derivatives thereof, and treated or untreated fermentation broth obtained by culturing the strains belonging to genus Zopfiella or Zopfiella curvata No. 37-3 strain, which show an excellent activities as antifungal agent and anti-thrombotic agent.
