Abstract: PURPOSE:To obtain a recording material having favorable color forming properties, raw preservability and stability of developed color images, by using a fluoran compound having an isopropyl group at 1-position as an electron-donative colorless dye. CONSTITUTION:A fluoran derivative having an isopropyl group at 1-position is used in a recording material utilizing a color forming reaction upon contact of an electron- donative colorless dye with an electron-acceptive compound. The dye rapidly forms a color upon making contact with the electron-acceptive substance. The coloring matter thus developed into color is substantially free of discoloration or fading even when being irradiated with light, heated or moistened for a long time, which is advantageous for long-time preservation of a record. The color former has excellent stability, so that it is free of changes in properties or coloring even after long-time preservation, and retains a sufficient color forming capability. The electron-acceptive compound may be an inorganic or organic Lewis acid or Bronsted acid. When the recording material is used as a thermal recording paper, the colorless dye and the electron- acceptive compound are used in the state of being dispersed through grinding to a particle diameter of not more than 10mum, preferably, not more than 3mum in a dispersant.

Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of error caused by abnormality in the transmission timing of optical signal by inspecting abnormality by comparing a clock signal contained in the received optical signal with a clock signal attached to transmission data. SOLUTION: A clock inspection circuit 20 inputs a reception clock outputted from an optical/electric module 10 and a transmission clock to be sent to a flip-flop 30 in order to get the transmission timing of transmission data. When both the clock signals are compared and abnormality is detected in any one clock signal, an alarm pulse is outputted until abnormality in this clock signal is canceled. The flip-flop 30 receives the transmission data and the transmission clock from a data processing part, etc., and sends them to an electric/optical module 40 at the timing to be measured based on the predetermined transmission clock. Thus, by comparing and inspecting the clock signals, the generation of error caused by abnormality in the transmission timing of optical signal can be prevented.
