摘要： PURPOSE: To make it possible to easily execute the detection, identification and quantitative determination of the electric field responsive impurities included in a liquid crystal element by detecting the impurities included in the liquid crystal element with high sensibility in accordance with the inclination of the electric field response curves within the time of the respective pulse widths in the state of impressing pulse electric fields varying in polarities from each other on the liquid crystal element. CONSTITUTION: The pulse signals generated by a pulse generator 1 are applied to a liquid crystal cell 10. This liquid crystal cell 10 is irradiated with the IR light from a light source 2 through a polarizer 3. The IR light transmitted through the cell is converted to an electric signal by an IR detecting means 4 and this signal is detected. The electric signal is amplified and is inputted to a digital sampling oscilloscope 7 by which the signal is time analyzed and integrated. The entire part of the evaluating device is controlled by a computer 8. The electric field response curves corresponding to the changes in the intensity of the transmitted light with lapse of time are respectively determined for the cases the pulse electric fields varying in the polarities from each other are impressed. The inclinations of the electric field response curves within the time of the respective pulse widths are analyzed.

摘要： PURPOSE:To improve the high-speed responsiveness with a voltage by forming the liquid crystal oriented films formed on the surfaces of substrates of high polymer films having a bipole moment with a rigid structure coupled via a surface treating agent. CONSTITUTION:A substrate formed by coupling the liquid crystal oriented film 4 consisting of a high polymer (PBLG) having a rigid structure and the bipole moment via a surface treated layer 3 on the surface of the ITO electrode 2 on a glass substrate 1 is used as a first substrate. A substrate constituted by forming a polyimide liquid crystal oriented film 7 not subjected to a rubbing treatment on the surface of a glass substrate 5 with the ITO electrode 6 is used as a second substrate. The substrates are disposed and sealed to face each other via spacers 8 in such a manner that a cell thickness of about 10mum is attained. Liquid crystal molecules are thereafter injected and encapsulated therebetween and are slowly cooled after heating, by which the liquid crystal 9 is oriented. A power source 10 is connected to the ITO electrode 2 and the ITO electrode 6 and a prescribed voltage is applied between both, by which the high-speed responsiveness with the applied voltage is realized.

摘要： PROBLEM TO BE SOLVED: To enable the detection of forgery in the image by an erasable image forming material. SOLUTION: A detecting material which contains a cyano group and is hardly visible when arranged on a base material is arranged on the base material before forgery is done. The detecting material is detected by measurement of the IR light emission or IR absorption of the base material formed with the image. The forgery is detected from the detected detecting material. The forgery of the image is detected by the change or annihilation by the image erasure of the detecting material or the mismatch of the detecting material arranged at the base material so as to match the image and the image. The erasable and forgery detectable image forming material contains a colorable compound, a color developer which is a color developer to cause the color development of the colorable compound by acting thereon and is capable of lessening the effect on the colorable compound by a decoloring agent and the detecting material which has the cyano group or fluorescence and is hardly visible when arranged at the base material.

摘要： PROBLEM TO BE SOLVED: To obtain a sorting apparatus by which a sheet of paper with an image formed of an image formation material, a sheet of paper with an image formed of an erasable material and a sheet of thermal paper can be sorted by a method wherein the reflection density of a sheet of paper to which a load is given is compared with a prescribed reference value. SOLUTION: Sheets of paper which are loaded so as to be mixed in a paper reservoir 1 are sent to an optical measuring system 5 via conveyance rollers 4, and their light transmittance and the mean vaue of their reflection densitities on both faces are measured. Then, the sheets of paper whose light transmittance is higher than a reference value are judged to be OHP sheets, and they are stored in an OHP sheet stockroom 7. Other sheets of paper are sent to heating rollers 8 so as to be heated, and the mean value of their reflection densities on both faces is measured by an optical measuring system 9. Then, the mean value of their reflection densities is compared with a prescribed reference value. Whether the sheets of paper are sheets of ordinary paper which are printed by an ordinary image formation material, or sheets of paper which are printed by an erasable image formation material, are judged. A sorting guide 11 and a sorting guide 13 are driven, and the sheets of paper are stored and stored in a thermal-paper stockroom 12, a recyclable-paper stockroom 14 and a reusable-paper stockroom 16.

摘要： PROBLEM TO BE SOLVED: To dissolve dispersion failure and obtain an excellent erased state even in the case of using an achromatic agent low in compatibility by containing a colored compound, a developer and a precursor of an achromatic agent with a functional group protected by a protective group. SOLUTION: A colored compound, a developer and a precursor of an achromatic agent with a protective group led in are combined to make image forming material erasable after printing. The compounding ratio of the developer is 0.1-10 pts.wt., preferably 1-2 pts.wt., to 1 pts.wt. of the colored compound. The compounding ratio of the precursor of the achromatic agent is set to 1-200 pts.wt., preferably 10-100 pts.wt., to 1 pts.wt. of the colored compound. As the colored compound, there is an electron donative organic substance such as leucoauramines or diarylphthalides. As the developer, there is an acid compound such as phenol, phenol metal salt or carboxylic acid metal salt. The achromatic agent with the protective group displays notable achromatic action when the protective group is dissociated, and a storol compound or the like is used.
