摘要:
The device comprises a recording-reading unit (1) and a mechanism (2) for storing and replacing the information carriers. The information carriers (5) have a cylindrical shape and are mounted with the possibility of rotation around their axes, in the mechanism (2) for storing and replacing the information carriers. The device relates to computer technology and may be used in the external memory of electronic computers.
摘要:
Polypeptides are obtained in a cell-free system containing exogenous RNA-polymerase, protein genes in the form of DNA molecules, nucleic acid and substrates. It contains, as substrates, ATP, GTP, CTP, UTP and aminoacids. The products obtained in the system include the desired polypeptide AMP, GDP, CDP, UDP, pyrophosphate and non-organic phosphate. In the course of translation process, as substrates are consumed and products are obtained, products are removed from the system, containing the desired polypeptide, AMP, GDP, CDP, UDP, pyrophosphate and non-organic phosphate, while ATP, GTP, CTP, UTP and amino acids are simultaneously fed in the system, as substrates, to maintain their initial concentration.
摘要:
An optical information carrier comprises a cylinder (1) with a recording layer (2) inside it, as well as bushings (3, 4) mounted on the butt-ends of the cylinder (1) and isolating the recording layer (2) from the outside space. A method of erasing information recorded on said optical carrier consists in the excitation of a high-frequency electrical charge inside a sealed closed cavity (5) of the cylinder (1). An optical memorization device for implementation of said method has an information erasing unit (11) comprising a high frequency charge excitation circuit with electrodes (12, 13), between which an optical information carrier (10) is placed in order to excitate a high-frequency charge inside its sealed closed cavity (5).
