A foliar spray agent containing an alkali metal silicate as an active ingredient protects agricultural and horticultural plants from disease injury by spraying on the leaves of plants. Treatment of agricultural and horticultural plants with the agent provides an increase in crop yields with high quality.

An aqueous solution, preferably an aqueous disinfectant solution, containing chlorine dioxide and which is capable of forming a foam, and methods for the preparation and use thereof. An aqueous disinfectant solution capable of forming a foam is prepared by adding a foaming agent, i.e., a suitable surfactant, to water. Chlorine dioxide may then be added to the solution or it may be generated in sit...

A zoom lens comprises a varifocal lens section having a variator lens unit for varying the focal length of the entire system and a compensator lens unit for compensating for the image shift with zooming movement of the variator lens unit, a relay lens section using a light beam from the varifocal lens section for forming an object image on a predetermined plane, a lens unit constituting at least p...

An image position detecting device for detecting relative positions of images of an object on a pair of image sensors. A pair of image data groups are derived from the pair of image sensors. The image position detecting device includes window-size designating means, correlative value calculating means, and highest-correlation detecting means. The window-size designating means determines the number...

PURPOSE:To eliminate the dependency of the liquid crystal display device on visual angles by inserting films which have an optical axis or ray axis substantially in the normal direction of a film and have light transmittability and uniaxially stretched films of a high polymer which has a negative intrinsic double refractive value and has light transmittability between a liquid crystal cell and a p...

PURPOSE:To obtain a good black display by forming a liquid crystal panel into multiple layers. CONSTITUTION:The liquid crystal panel is made into multiple layers.
