Abstract: A test substance detection method includes: a step A in which a sample containing a test substance and water, a compound having a structure in which a response site and a recognition site are connected via a spacer, and a surfactant are added; and a step B in which the recognition site and the test substance interact and a response at the response site arising from the interaction is detected. Further, also provided are: a purified water production method and an injection water production method both using the foregoing; a detection agent composition containing a compound represented by Formula (1) and a surfactant; and a detection apparatus, a purified water production facility, and an injection water production facility, all using the foregoing.

Abstract: An operation for selecting a desired one of images can be simplified. Still image data sets are sequentially read from a recording medium according to order of file names and displayed on a TV. Upon display, the still image data sets are in a non-selection state. If an instruction is not input from a remote controller within a predetermined time since the display of one of the still image data sets, the still image data set being displayed is set to a selection state and the following still image data set having the file name that comes next is displayed. If an instruction is input from the remote controller for display of the following still image data set within the predetermined time, the still image data set being displayed is left in the non-selection state, and the following still image data set is displayed.

Abstract: In a one-chip microcomputer that incorporates a nonvolatile memory in which data can be electrically erased and data can be written and read, as a program memory, a reference nonvolatile memory group 40 which is lower in characteristic than a nonvolatile memory 7 in a memory cell array is disposed, and, on the basis of a result of reference of the reference nonvolatile memory group 40, the erase voltage of an erasing operation which is previously stored in a specific address region of the nonvolatile memory 7 is changed by a control circuit 44. On the basis of a result of reference of the reference nonvolatile memory group 40, the reference level of a reading operation of a sense amplifier which is previously stored in a specific address region of the nonvolatile memory 7 is changed by the control circuit 44.
