Abstract: A power consumption-demand/supply adjustment apparatus comprises: a monitor for a consumption amount of supplied power and the quality of supplied power; a contract-adjustment means for supporting establishing of contract for a power demand/supply by adjusting power demand conditions of a customer and power supply conditions of a power supplier; and banking means for requesting a charge of the consumption amount of supplied power and the quality of supplied power, and a charge to be paid from an accumulated deposit based on the contract; wherein the banking means requests the charge of supplied power and the charge to be paid from an accumulated deposit based on monitoring information sent from the monitor.

Abstract: A detecting device for road monitoring which detects traveling states of vehicles on a road (traffic stagnation, stopping of vehicles, etc.) or fallen objects on a road is provided. Luminance change detecting unit prepares background image data by taking a time average of luminance for each picture element, and detects image portions where inputted image data is different in luminance from the prepared background image data. Hue change detecting unit prepares background image data by taking a time average of hue for each picture element, and detects image portions where inputted image data is different in hue from the prepared background image data.

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: A print evaluating apparatus includes an image reader having a plurality of photoreceptors to read a print pattern line by line; a relative movement causing device for imparting relative movement between the print pattern and the image reader in a direction different from a direction in which the photoreceptors are arranged; and a processor for effecting plural operations in parallel for plural evaluation items for image signals corresponding to the print pattern supplied by the image reader during the relative movement, and for effecting evaluation on data provided by the operations.

Abstract: A novel 3(2H)-pyradazinone derivative of the formula (I) ##STR1## wherein, R represents an alkyl group having 1 to 4 carbon atoms substituted by a cycloalkyl group having 3 to 8 carbon atoms, an alkyl group having 1 to 4 carbon atoms substituted by a phenyl group which may be substituted or an alkyl group having 1 to 4 carbon atoms substituted by a heterocyclic group, R' represents a hydrogen atom, a halogen atom, an alkoxy group having 1 to 4 carbon atoms or a hydroxyl group having 1 to 4 carbon atoms, J represents any of various organic radicals. There is also provided a process for preparing said derivatives. These derivatives are useful as active ingredients of insecticidal, acaricidal and/or nematicidal compositions for agricultural and horticultural uses as well as of expellent compositions for pests parasitic on animals.

Abstract: The present invention provides novel strains of Bacillus thuringiensis var. Kurstaki, No.145, No.116 and No.161.These strains produce an insecticidal crystal toxin which is useful as an active component in a insect pest-controlling agent.
