Abstract: PURPOSE:To improve the stability of a base current in a carbon electrode and thereby to improve the precision in analysis and reproducibility, by a method wherein the density and the size of an opening existing in a working electrode are set at specified values. CONSTITUTION:A sample liquid to be quantified is supplied from a high-speed liquid chromatography 1 into an introduction port 2, made to contact with a working electrode 4 covered with a Teflon seal 3, made further to contact with a reference electrode 5 and then discharged from a discharge port 7 to which an auxiliary electrode 6 is fitted. Between the working electrode 4 and the reference electrode 5 a voltage is impressed from a power source 8. A current value of the working electrode 4 is relation to the eluation volume of the sample liquid passing from the introduction port 2 to the discharge port 7 is measured for analysis by a current measuring device 9. Besides, the working electroe 4 has openings whose density is 2X10 /mm bellow and whose maximum diameter is 0.5mum or below, and it is formed of an isotropic carbon material. By using a surface-polished vitreous carbon material as this carbon material, S/N can be improved and thus a stable analysis can be attained.

Abstract: PURPOSE:To provide an optical recording medium light in weight, free of toxicity, having excellent stability and easy to produce, by using a polished carbonaceous material for a recording layer, and utilizing variations in the Raman spectrum caused by irradiation with laser beams for recording information. CONSTITUTION:A recording layer is constituted of a carbonaceous material, and it is preferable that a base and the recording layer are constituted of the same carbonaceous material. The carbonaceous material means a material consisting solely of carbon or comprising carbon as a main constituent, such as an extremely highly crystalline and highly oriented carbon, coke, vitreous carbon confirmed to be amorphous by X-ray analysis and carbon black in which ultra fine particles are aggregated. Particularly preferably, a vitreous carbonaceous material is used. Information is written into and read from a optical recording medium by a laser beam. A laser light source may be, for example, a neon, helium-cadmium, argon, helium-neon, ruby or semiconductor laser device.

Abstract: PURPOSE:To improve the durability of the title part and to reduce frictional resistance with a recording medium by using vitreous carbon as the deposition source and radiating particles having kinetic energy at more than a specified value into a vacuum and depositing the coated film of the vitreous carbon. CONSTITUTION:The coated film of vitreous carbon is formed on the surface of the sliding-contact part of a recording medium which is brought into contact with the recording medium. In this process, vitreous carbon is used as the deposition source and the particles having 1eV kinetic energy are radiated into a vacuum to deposit the particles as the coated film of vitreous carbon. For example, vitreous carbon is deposited on the surface of a magnetic head 1 which is brought into contact with a recording head medium to form a coated film 2. a sputtering method or a cluster-ion beam method is used as the depositing method. A sliding-contact part having excellent durability and without damaging a recording medium can be thus produced.
