    摘要: A sheet resist apparatus disposed in a transporting path of a recording sheet transported from a sheet supplying unit to an image forming unit in an image forming apparatus, includes: a pair of first rollers disposed in the transporting path; a pair of second rollers disposed in the transporting path at a downstream of the first rollers; a first driving device for rotating the first rollers to transport the recording sheet toward the second rollers; and a second driving device for rotating the second rollers to transport the recording sheet, which is transported from the first rollers, toward the image forming unit in synchronization with a timing of image-formation of the image forming unit. The sheet resist apparatus further includes: a sensor disposed between the first rollers and the second rollers for detecting a tip of the recording sheet transported from the first rollers; and a control device for controlling the first and second driving devices on a basis of a result of detection of the sensor, such that the first driving device stops driving once before the tip of the recording sheet reaches the second rollers, and such that the first driving device resumes driving earlier than the second driving device starts driving by a predetermined time period.

    摘要: A method for detecting earthquakes comprises the steps of picking up pre-earthquake long waves or earth currents at four or more observation points located underground or at the sea bottom, carrying out a computation based on the interrelation among the so-obtained= signals to obtain the three-dimensional distribution of the sources and intensities of the long waves or earth currents, and predicting the focal region, scale and time of occurrence of earthquakes from the time-course variation in the so-obtained three-dimensional image of the wave source.
