Abstract: In an on-board display apparatus, a transmission type display device is provided in front, displays a touch switch display when necessary, and operates as a touch panel. The transmission type display device can be turned to be transparent, and an image display device is provided rearward of the transparent portion. Since the display screen of the image display device toward the back, the visual range is long, and visibility can be improved. Since the display screen of the image display device and the display screen of the transmission type display device are not on the same plane, even if the touch switch display is touched by a finger, an image can be seen, and a pointer can be displayed on the display screen of the image display device in a position corresponding to the touched position.

Abstract: Provided are a DNA carrier where DNA is firmly held in a substrate, which can reduce the elution of DNA into water and can take full advantage of the capability of DNA to selectively and specifically collect a substance; and a method of producing the DNA carrier. Also provided is a collection system using DNA, which can be used in the high-accuracy detection of a particular substance and in an environmental cleanup capable of efficiently removing a substance, in which the DNA carrier is used to collect the substance contained in air or water by taking full advantage of the capability of DNA to selectively and specifically collect the substance. The DNA carrier is one where DNA is held in a porous matrix containing polyorganosiloxane with a basic functional group and particles. Preferably, the polyorganosiloxane with a basic functional group contains a hydrolysis condensate of one or more of particular silane compounds with an amino group.

Abstract: A solution temperature control device in a biological cell observing chamber (30) used for the detection of chemotaxis and chemotactic cell separator, comprising a first temperature controller (62) and a second temperature controller (63). The first temperature controller (62) measures the temperature of a solution filled in a pair of wells and a flow passage in the chamber and controls the temperature to a specified temperature, and the second temperature controller (63) measures the temperature of a heating part (64) which heats the chamber (30) from the outside to indirectly heat the solution filled in the pair of wells and the flow passage and controls the temperature to a specified preheat temperature. Since the state and quantity of cells moving from one well to the other through the flow passage while holding the temperature of the solution at a specified temperature can be accurately observed and measured, accuracy for controlling the temperature of the solution can be remarkably increased.
