Abstract: The present invention is a tape drive system (1) comprising means to support and drive first and a second tape reels (4, 5), tape guides (7, 8), a transducing head (6) for reading or writing data, said system having a tape feed path from the first tape reel (4) to the second tape reel (5) around the tape guides (7, 8), the feed path including a wrap section wherein a portion of the tape is wrapped over an exposed part of the tape wound upon one of the tape reels (4), the wrapped portion of the tape forming a squeeze bearing realised in the presence of a thin film of air between the two surfaces of the tape constituting the bearing.Said squeeze bearing damps tape tension variation, inhibits the transmission of vibrations from one reel to the other, and eliminates the entrapment of entrained air without any additional rollers or other components. The tape path is suitable for use in a peripheral storage device, such as a magnetic tape drive, and is compatible with a variety of tape cartridge configurations.

IPC: H04B10/2513
Filed: 1993-01-23
Abstract: In the transmission of digital signals via optical fibres (3) which have a considerable chromatic dispersion at the wavelength used, the length of the transmission link is very limited if the digital signal to be transmitted is converted into an optical signal by means of intensity modulation. If a frequency modulation (also called FSK = frequency shift keying) is used instead of the intensity modulation, the length of the link which can be bridged can be greatly increased but a suitable optical receiver is needed at the receiving end. According to the invention, a simple optical receiver (4) is used which is not sensitive to frequency modulation but to intensity modulation. This is possible because, due to the chromatic dispersion of the optical fibre (3) and resultant differences in transit time of signal components of different wavelengths ( lambda 0,  lambda 1), the initial frequency modulation becomes an intensity variation in the course of the transmission via the optical fibre (3), the course of which variation contains the digital signal to be transmitted. <IMAGE>

Abstract: To locate and eliminate faults in electronic control units (K) which are connected to a central station (Z), a fault program (FP) is provided in the central station (Z), which, in collaboration with a central file (ZD) outputs instructions for eliminating the faults to the control units (K). The control units (K) are interrogated for fault messages (F) in interactive mode, which are evaluated in the central station (Z) using auxiliary programs (HP). If the central station (Z) is not capable of locating a fault, a corresponding information item is forwarded to a decentralised station (D). The auxiliary programs (HP) operate in conjunction with auxiliary files (HD) and output instructions for fault tracing and/or module exchange to the control units (K). Control units (K) provided are preferably communications systems for telephone and/or data communication. <IMAGE>

Abstract: A punching apparatus punches a sheet of paper into products and a scrap by a flat pattern being implanted with blades of a shape of a product. No prior punching apparatus cannot separate products from a scrap at the time when products have been punched. This invention uses a flat pattern(K) upside down. The flat pattern have closed-loop blades on the bottom surface. The blades shape products. A lower roller (2b) presses a sheet of paper to the blade-implanted bottom surface of the flat pattern. Products are punched out from the sheet by the blades one by one, while the flat pattern progresses and the lower roller rotates. The products are withdrawn from one side of the punching section. The scraps are taken out from the front part of the punching section.

Abstract: The invention relates to a magnetic field sensor having a magnetoresistance element, comprising a substrate on which two ferromagnetic layers are provided which exhibit a uniaxial in-plane anisotropy and which are separated by a non-magnetic intermediate layer. In accordance with the invention, the anisotropy direction of one ferromagnetic layer extends transversely with respect to the anisotropy direction of the other ferromagnetic layer. By virtue thereof, it is attained that the change of the direction of magnetization in the sensor caused by external magnetic fields is much more uniform and that the corresponding magnetization curve exhibits a smaller hysteresis. When the sensor is used in a magnetic head, an improved signal/noise ratio is obtained.

Abstract: A chemical analysis film cartridge (20) has a box-like casing body (21) which has first and second end walls (20d,20a) opposed to each other and in which a plurality of dry frameless chemical analysis film chips (1) are stored in a stack extending between the end walls. A first opening (20c) is formed in a side wall (20b) of the casing body at a portion near to the first end wall (20d) of the casing body so that only the film chip nearest to the first end wall in the film chips in the stack can be taken out of the casing body through the first opening by moving the film chip in the direction perpendicular to the direction of the stack. A second opening (20e) which permits a suction pad to hold the film chip nearest to the first end wall and take it out of the casing body through the first opening is formed in the first end wall of the casing body. The width of the first opening is larger than the thickness of one film chip and smaller than double the thickness of one film chip at least a part of the first opening. The suction pad is retracted with the film chip held on the suction means so that the film chip held on the suction pad abuts against the edge of the second opening on opposite sides of the suction pad and then further retracted to pull the central portion of the film chip in this state into the second opening, thereby reshaping the film chip into a predetermined warped-shape conforming to the shape of the first opening.

Abstract: A method and system for automatic formatting of user selected text in a word processing system. A number of format options are displayed to the user and a text format selection is then obtained from the user for a selected format option. An identifier identifying the selected text format is stored in a text format data structure. One or more portions of existing text are thereafter selected by the user. For each selected portion of existing text, the selected portion is formatted with the text format identified by the identifier stored in the data structure. These steps are repeated until canceled by the user or until the user enters new text. In a preferred embodiment, the word processing system provides a conventional mode for performing conventional text formatting in which a text format is specified only after a single portion of existing text is selected by the user to which to apply the specified text format. The word processing system also provides an automatic formatting mode for automatically formatting any number of selected portions of text with a selected text format, as described above. By selecting a text format without first selecting a portion of existing text to which to apply the selected text format, the user places the word processing system in automatic formatting mode. Canceling the selected text format or entering new text converts the word processing system back to the conventional mode.
