A reversible thermosensitive coloring composition is composed of (i) an electron-donor coloring compound and (ii) an electron-acceptor compound selected from the group consisting of an organic phosphoric acid compound, an aliphatic carboxylic acid, and a phenolic compound, each having a straight chain or branched chain alkyl group or alkenyl group having 12 or more carbon atoms, the electron-donor coloring compound and the electron-acceptor compound being capable of reacting to induce color formation in the reversible thermosensitive coloring composition at the eutectic temperature thereof. The electron-donor coloring compound and the electron-acceptor compound, when fused and colored in a mixed state, with application of heat thereto, followed by rapidly cooling the fused mixture, exhibit an exothermic peak in a temperature elevation process in a differential scanning calorific anlaysis or in a differential thermal analysis. A recording medium and display medium using the above reversible thermosensitive coloring composition, a recording method of using the recording medium, a display method of using the display medium, a display method of using the display medium, and a display apparatus using the display medium are disclosed.

A configuration measuring apparatus includes a contacting member for contacting and tracing a surface of an object to be measured, a supporting member for supporting the contacting member and having a reflecting surface, an optical probe, a driving device, and an X-coordinate or XY-coordinate measuring device. The optical probe supports the contacting member through the supporting member and has an automatic focusing device for moving an objective lens in the Z-direction, which is an optical direction of the lens, so that a focusing point of the objective lens is positioned at the reflecting surface in spite of a possible dislocation of the reflecting surface, which is to be at a focusing position of the objective lens for condensing a laser beam and a device for measuring a Z-coordinate of the reflecting surface by allowing interference of the laser beam which has been reflected by the reflecting surface with a reference light. The driving device moves the optical probe in the X-direction or the XY-direction. The X-coordinate or XY-coordinate measuring device measures a position of the optical probe in the X-direction or the XY-direction. Then, the configuration of the surface of the object in XZ-coordinate or XYZ-coordinate is measured by the optical probe in cooperation with the contact member which traces the surface of the object.

摘要:
A velocity signal is obtained by calculating both the selected signal of the differentiated signal of the position signal from a position detector and the selected signal of the sinusoidal wave signal according to position displacement, so that a velocity detection produces a smaller velocity detection error at a low velocity and generates no ripple component even when a high velocity is detected.
