Patent EP-0381848-A2 (EP)
Inventor: SCHMIDT ROBERT
IPC: G01N27/90
Filed: 1989-12-21
Abstract: In eddy-current nondestructive testing of the surfaces of work pieces, the test apparatus comprises an eddy-current device (2) which delivers the necessary excitation signals for a probe pad (4) resting on the surface of the test piece and simultaneously processes the response signals returning from the test piece to produce an interpretable display, for example on a display screen. The eddy-current pad comprises a matrix-like arrangement of individual elements (4c) which are connected electrically via a multiplexer circuit (3) in such a way that they can be individually scanned in accordance with a timing diagram preset by a computer (1). From the timing sequence, the positional coordinate of the respective test point can be determined by the computer and processed together with the test signal to produce a surface image display (1b', 1b"). In order to prevent the probe elements influencing one another, decoupling measures are necessary. These can be implemented by means of line and column separation of the transmitting and receiving coils using diode circuitry if transmitting and receiving function are performed by the same coils or by a combination of the two. Other types of decoupling are based on the use of Hall probes or magnetic diodes in combination with transmitting coils. <IMAGE>

Abstract: MOVPE growth and photoetching are integrated into a unified sequence which is carried out without removing a workpiece from a MOVPE reactor. Growth may be carried out before, after or before and after the etching. 
     To prevent pattern broadening by diffussion of the active species the substrate is preferably protected by a fugitive coating which is removed by the illumination. Native oxide coatings are particularly suitable for InGaAsP substrates. These are conveniently applied by exposing to substrate to 20% 0₂ + 80%N₂ for about 3 minutes at 450°C.

Abstract: In driving a stepping motor (1) which, for example, is used to effect tracking movements of a head (5) in an electronic still camera or other magnetic disc recording and/or reproducing apparatus, and which has a rotor (1C) and a plurality of phases (1A, 1B) to which input pulses are applied in predetermined sequences for establishing excitation states by which the rotor (1C) is stepped to respective positions, the input pulses are controlled for alternating between first and second excitation states corresponding to adjacent stepped positions between which it is desired to bring the rotor (1C) to rest. Such alternation is initially effected at a relatively low frequency so that the rotor (1C) oscillates between the stepped positions corresponding to the first and second excitation states, respectively, and then the frequency of alternation between the first and second excitation states is gradually increased to a value at which the rotor comes to rest at a position between the stepped positions. A duty ratio is selected for the first and second excitation states which inversely corresponds to the ratio of the distances from the desired position of rest of the rotor (1C) to the stepped positions thereof corresponding to the first and second excitation states, respectively, and such duty ratio is applied to the alternation between the first and second excitation states at least during the increasing of the frequency of alternation to the value at which the rotor (1C) no longer oscillates.

Abstract: Compounds are disclosed for treating AIDS, herpes, and other viral infections by means of lipid derivatives of antiviral agents. The compounds consist of nucleoside analogues having antiviral activity which are linked, commonly through a phosphate group at the 5′ position of the pentose residue, to one of a selected group of lipids. The lipophilic nature of these compounds provide advantages over the use of the nucleoside analogue alone. It also makes it possible to incorporate them into the lamellar structure of liposomes, either alone or combined with similar molecules. In the form of liposomes, these antiviral agents are preferentially taken up by macrophages and monocytes, cells which have been found to harbor the target HIV virus. Additional site specificity may be incorporated into the liposomes with the addition of ligands, such as monoclonal antibodies or other peptides or proteins which bind to viral proteins. Effective nucleoside analogues are dideoxynucleosides, azidothymine (AZT), and acyclovir; lipid groups may be glycolipids, sphingolipids, phospholipids or fatty acids. The compounds persist, after intracellular hydrolysis, as phosphorylated or non-phosphorylated antiviral nucleosides. The compounds are effective in improving the efficacy of antiviral nucleoside analogues by prolonging the antiviral activity after the administration of the drug has ended, and in preventing retroviral replication in HIV infections which have become resistant to therapy with conventional forms of the antiretroviral agents.
