Abstract: Coordinates of a first region extraction window, a first sample stage coordinate, a second sample stage coordinate, and a second region extraction window, including images of one sample stage and an observation target tissues of a sample when the one sample stage is respectively positioned on two microscopes are respectively obtained. Based on difference between the first sample stage coordinate and the second sample stage coordinate, the second sample stage coordinate is corrected. Based on the obtained corrected second sample stage coordinate, the second positioning unit is moved from the second non-observation position to the second observation position where the second region extraction window is located at a position corresponding to the coordinate position of the first region extraction window.

Abstract: A photoelectric sensor comprises a control unit which is configured to store in a memory data on the amount of received light input from a light-receiving unit or measurement data obtained by a measuring process, and to perform a sampling process in which the data stored in the memory are read at fixed intervals as sampling data, the sampling process being performed within a limited reading period. Further, the control unit outputs the thus read sampling data so as to correspond to the order in which they are stored in the memory.

Abstract: A photoelectric sensor comprises a control unit which performs a measuring process for data on an amount of light input from a light-receiving unit. The control unit measures the length TPS of period (from point a to point d) from when measurement data starts to change in the direction of a threshold P0 to when the amount of received light returns to the level at which the measurement data started to change, and the length TON of period (from point b to point c) for which the detection signal is ON-level. The control unit then outputs information on a margin for TPS with respect to TON on a display unit provided for the photoelectric sensor or to an external device in order to display them.

Abstract: A method and an apparatus for automatically editing audio signals by determining an editing section on a recording medium having the signals recorded thereon. A first editing point is searched for on the recording medium, and the location of that point is stored in a memory. A second editing point is searched for on the recording medium. The location of the first editing point is compared with that of the second editing point. One of the two locations is set as an in-point and the other location as an out-point in accordance with the result of the comparison. The editing section determined by the in- and out-points is displayed on a screen.
