IPC: H04B10/07
Filed: 1991-07-17
Abstract: A radio communication apparatus (21) is tested by not only a radio test signal but also an optical test signal.  Each test signal carries a test digital data signal.  The apparatus has a radio processing section (24, 25) for processing the radio test signal into the test digital data signal. A data processing section (28, 29) processes an input data signal into a processed data signal.  Responsive to the processed data signal, an announcing section (30, 31) announces generation of the processed data signal.  An optical processing section (32, 27) processes the optical test signal into the digital data signal.  Connected to the radio and the optical processing sections and to the data processing section, a selector (26) selects, as the input data signal, one of the test digital data signals produced by the radio and the optical processing sections.

Title: Method of operating a communications system, a communications system anda secondary station for use in the system
Inventor: OWEN FRANK CHARLES GWYN
IPC: H04M1/72516
Filed: 1991-12-11
Abstract: A communications system, such as DECT, comprises a plurality of geographically separate primary (or fixed) stations (PS) and a plurality of secondary (or portable) stations (SS) which are able to roam relative to the primary stations. Communication between the primary and secondary stations is by way of any one of a plurality of TDD radio channels. A primary station when idle transmits an idle beacon signal onto which an idle primary station can lock by scanning the radio channels. However a secondary station which has roamed out of coverage range of the primary stations can save battery power by progressively increasing to a maximum time value the time interval between successive scans.

Title: Method of preparing a plasmid having both the ability to express a retroviral gene and the ability to process expression products after translation, the resultant plasmid and expression products thereof
Inventor: SAITO ATSUSI
IPC: C12N15/55
Filed: 1990-11-30
Abstract: The  present  invention  provides  a  method  of preparing plasmids having the ability of expressing retroviral   genes   and/or   effecting   the  post-translational processing  of  the  encoded products, and  the  resultant  plasmid  and  the  expression products thereof.  A method of the present invention is to prepare a plasmid by insertion-linking a cDNA fragment containing at least the protease gene from among retroviral genes with a highly expressing gene or an expression vector for the direct expression of its gene products, thereby causing expression of the retroviral genes, and at the same time, to process said expression product itself with the protease in that expression product, thereby mass-producing the retroviral genes.   These retroviral genes comprise three kinds of core protein encoded by gag gene, and three kinds of enzymes encoded by pol gene, in the form of individual single mature or active proteins. Alternatively,  the method of the present invention is to prepare a plasmid in which a cDNA fragment containing HIV nef gene region is inserted into a highly expressing gene and an expression vector for the direct expression of its gene products, thereby mass-producing Nef protein which is the expression product of nef gene.
