Abstract: A method of pretreating an overwritable opto-magnetic recording medium disc by modulating merely the intensity of an optical beam without modulating the direction of a recording magnetic field. The opto-magnetic recording medium comprises at least a multilayered vertically magnetized film having a two-layered structure of a recording layer (first layer) and a recording assisting layer (second layer). Data are recorded in the first layer (and also in the second layer, at times) by applying a laser beam to the recording medium in the form of bits having "A direction" magnetization and bits having "direction opposite to A" magnetization. When the intensity of the laser beam is on a high level, "A direction" magnetization of the recording assisting layer (second layer) is reversed to "direction opposite to A" magnetization by the recording magnetic field Hb so as to form the bits having "direction opposite to A" magnetization (or "A direction" magnetization) in the recording layer (first layer) by "direction opoposite to A" magnetization of this second layer. When the beam intensity is on a low level, bits having "A direction magnetization" (or "direction opposite to A" direction) are formed in the first layer by "A direction" magnetization of the second layer.

Abstract: A computer I/O system which includes a dynamic switch (10) having a plurality of ports (P) and a plurality of link-level facilities, with each link-level facility being attached to an individual one of the ports (P). Whenever the state of a port (P) or its attached link-level facility is changed in such a way that the attached link-level facility's ability to communicate with another link-level facility might be affected, this fact is recognized by a dynamic switch control unit (20) which causes a state change notification (SCN) frame to be transmitted to all other link-level facilities which might be affected. The link-level facilities receiving such a state change notification then determine if any of the associations or potential associations with the link-level facility which caused the state change notification are affected.

Abstract: A control system for a wheeled vehicle, comprises a brake actuator for controlling a behavior of the vehicle during braking by producing a braking force difference between a left wheel braking force and a right wheel braking force in response to a control signal, a sensor (11) for sensing an actual vehicle motion variable such as a yaw rate, and a controller (8) for controlling the vehicle motion by producing the control signal. The controller determines an estimated vehicle motion variable from a driver's steering command by using one or more predetermined estimator transfer characteristics, compares the sensed and estimated vehicle motion variables to determine a deviation therebetween, and determines the magnitude of the control signal so as to reduce the deviation by using a predetermined compensator transfer characteristic and a predetermined filter transfer characteristic for filtering the deviation.

Abstract: A tight buffered optical waveguide fiber having improved strippability is provided. The fiber includes a core (12), a cladding (14), a first protective coating (16) in contact with the cladding, an interfacial layer (13) in contact with the first protective coating, and a buffer layer (18) in contact with the interfacial layer. The interfacial layer comprises a solid lubricant (60) such as sub-micron particles of polytetrafluoroethylene (PTFE) in a film-forming binder. The concentration of particles at the external surface of the interfacial layer (13) is preferably greater than the concentration at the internal surface so that the interfacial layer is more adherent to the first protective coating (16) than to the buffer layer (18). This differential adhesion facilitates the manufacturing process while still allowing long lengths (e.g., a foot or more) of either the buffer layer or both the buffer layer and the first protective coating to be removed from the cladding without damage to the fiber's physical and optical properties. A countercurrent technique for applying the interfacial layer to the fiber as a water dispersion is also disclosed.

Abstract: A method of reducing in a digital time multiplex mobile telephony system the risk of poor reception as a result of the occurrence of points of low signal strength, so-called zero points. Transmission from fixed stations is effected with a polarization direction which is changed stepwise between different parts of the transmitted information. This causes the fading patterns around receiving stations to change in time, and also causes any zero points to be moved in the geography, therewith making it improbable that more than a small part of an information frame will be lost. In the case of a GSM-type system, the polarization direction is changed for each new TDMA-frame.

Title: Method for the light-induced immobilization of biomolecules on chemically "inert" surfaces.
Inventor: SIGRIST HANS
IPC: C12N11/00
Filed: 1991-04-11
Abstract: The invention concerns a process for the photochemically induced immobilization of biomolecules (protein molecules, nucleic acids, lipids, carbohydrates). The process makes it possible to immobilize biomolecules by covalent bonding in molecular layers on "inert" substrates. The bonding reaction is activated by light irradiation in the absorption region of photo-activatable reagents or by supplying the appropriate amount of electrical energy and therefore is not aggressive. Substrates (e.g. glass, organic or inorganic plastics, silicon films, mica) are pre-treated by prior art methods in such a way that they can be derived with hetero-bifunctional photo-activatable wetting-agent molecules. Multiple-derived polymers can also be used as linker molecules to simultaneously bond ligand and substrate. Diazirines or aryl azides, for instance, can be used as the photo-activatable function. The chemical properties of the non-photo-active heterofunctions depend on the functional groups with which the substrate or linker molecules were previously derived (e.g. amino, carboxyl, thio groups). Coating the substrate with a hetero-bifunctional wetting-agent molecule gives a substrate with a photo-active surface coating. Owing to the high reactivity of the photo-generated intermediate products (carbenes, nitrenes), biomolecules of different chemical composition are covalently bound by light activation of the substrate, without the need for limiting reaction conditions. Length of irradiation time and intensity and wavelength of the light used (i.e. the energy used), as well as the frequency of occurrence of the photo-activatable groups on the substrate (packing density) determine the bonding efficiency and the size of the area occupied.

Abstract: A disk recording and reproducing apparatus which records and reproduces input signals converted into a digital form by using a disk-like recording medium. By combining the recording/reproducing mode in the tracking mode and the track jump operation together, signals are recorded at a constant linear velocity at all times independent of the input data rate. That is, after the recording of the selector is finished, an instruction (108) of a track jump to one track before is given to a tracking control means (6), and an optical head (5) is driven by a tracking control output (106) so as to make a jump onto a track which is on the inside by one track. Thus the operation of the apparatus is changed to the reproduction mode. Therefore, without vacant area in the disk, the data can be continuously recorded in time series. Moreover, simultaneously monitoring to maintain the reliability of the recorded data, or the re-recording function corresponding on the error conditions are easily realized by effecting similar track jump control.
