Abstract: A petri dish that includes a cell trapping portion having a plurality of suction holes. A cell-contained liquid is placed in the petri dish and the cell-contained liquid is sucked from the suction holes, which are smaller that the cells, from below the petri dish to trap the cells in the suction holes. The petri dish includes a liquid retaining portion having a space of a capacity that allows sucked-liquid, which is liquid sucked through the suction holes and that do not contain cells, to be retained therein, and configured so that an interface between the sucked-liquid in the space and gas being positioned at a lower level than a surface level of the cell-contained liquid in the petri dish.

Abstract: A cell trapping plate traps a cell by applying a negative pressure suction through a trapping hole provided therein. A capillary needle is stuck into the trapped cell to inject an injectant. The cell trapping plate includes trapping holes arranged at irregular intervals in directions of two coordinate axes in a two-dimensional orthogonal coordinate system.

Abstract: An optical pickup for an optical storage device includes a stem, a substrate mounted on the stem, and a laser diode mounted on the substrate. The substrate is integrally formed with an optical signal detector and an error signal detector for focusing error detection and tracking error detection. A cap is mounted on the stem so as to accommodate the substrate and the laser diode. A beam splitter unit including a polarization beam splitter and a beam splitting element is mounted on the cap. A hologram for diffracting a reflected beam toward the error signal detector is interposed between the cap and the beam splitter unit. The substrate is biased at a given potential, and has an insulating film opposed to the stem.

Abstract: A method for producing an optical module assembly includes the steps of illuminating an optical surface of an optical device included in an optical module, acquiring an image of the optical surface of the optical module, obtaining a position of an end surface of the optical fiber with respect to the optical surface of the optical device based upon the image of the optical surface, and positioning the end surface of said optical fiber at the position thus obtained. An apparatus for carrying out the method is also disclosed.

Abstract: A robot profile control system permits a force control robot to perform a profiling operation on a surface of a work object having curved surfaces of unknown contours. The robot profile control system resets a profile coordinate system for the profile operation on the basis of force acting between the end of the robot and the work object. The force is detected by a force detecting section of the robot profile control system.
