摘要： A method of analyzing a nucleic acid fragment sample to judge whether the nucleic acid fragment sample is uncomplementary, partly complementary or complementary to a DNA fragment in its specific base sequence is conducted by the steps of: bringing an aqueous solution of the nucleic acid fragment sample into contact with a DNA chip having an electroconductive substrate and the DNA fragment fixed onto the substrate in the presence of an electrochemical thread intercalator; measuring an electric current flowing from or to the electroconductive substrate along the DNA fragment under application of a potential to the substrate; and comparing the electric current measured above with a referential electric current which is prepared employing a DNA chip equivalent to the above DNA chip, the intercalator, and an aqueous solution of a nucleic acid fragment which is complementary to the DNA fragment of the DNA chip.

摘要： An apparatus for monitoring the immediate surroundings of a vehicle displays on a display within the vehicle cabin a captured image of the vehicle immediate surroundings captured by a camera mounted on a back door which can open and close. The apparatus determines whether the back door is open based on a signal output from a back door courtesy switch. If it is determined that the back door is open, a written notification that the back door is open is superimposed on the display showing the captured image from the camera. If it is determined that the back door is not open, the written notification is not shown.

摘要： A front camera for filming an area stretching forwards is disposed in a front portion of a vehicle. A side camera for filming an area stretching laterally and diagonally forwards is disposed in a lateral-left portion of the vehicle. An indicator display that can be visually recognized by a driver is disposed in a compartment of the vehicle. An amount of change in the direction of the vehicle, that is, a deflection angle of the vehicle is detected on the basis of a vehicle speed and a steering angle of a steering wheel, which have been detected by means of various sensors. After the indicator display has started displaying a lateral photo image filmed by the side camera, the photo image displayed by the indicator display is shifted from the lateral photo image filmed by the side camera to a front photo image filmed by the front camera if the deflection angle has reached a predetermined angle.
