Inventor: UHDE DIETMAR
IPC: G11B5/31
Filed: 1991-04-15
Abstract: There is no known feasible way of producing a true thin-film magnetic tape head with azimuth. A gap inclination (azimuth) can be made only by mechanically machining the substrate. The aim of the invention is to produce a thin-film magnetic tape head without putting two half-blocks together. According to the invention, a thin-film magnetic tape head (1, 6, 7, 8, 9) is produced in fifteen process stages in which the 'hour-glass effect' is of prime importance. The process of the invention for producing a thin-film magnetic tape head combines the advantages of planar thin-film technology and gap production with the magnetic and mechanical advantages of conventionally manufactured heads. Magnetic tape devices, especially video recorders.

Abstract: A paper holder assembly has an axle coaxially positionable to extend axially outwardly from axially opposite bases of a platen drum providing a circumferential outer surface disposed between the opposite bases, the axle has circumferential grooves terminated by corresponding flanges. A pair of brackets each having three arms joined together in a unitary monolithic structure with first and second arms defining a centrally disposed recess having spaced-apart curved sides are positioned to ride along corresponding ones of the circumferential grooves. A pivot pivotally connects the second arms to the opposite bases of the platen drum, and a paper holder extending from the distal portion of the third arm holds edges of sheets of paper against the circumferential outer surface projecting axially inwardly from distal ends of the third arms across the circumferential outer surface. Springs bias the bracket toward a first orientation relative to the pivot. Rotating the brackets and paper holder against the bias springs releases the leading edge of the paper from the platen drum; by discharging a paper under frictional force just after completion of printing of the last color, a substantial length of a ribbon is saved by advancing the ribbon only for printing. Thus, when printing a third color after printing the first and second colors, the rotation of the paper holder enables the partially printed paper to be lifted away from the platen by its intrinsic resilient force. As a result, printing of the last color is performed simultaneously with discharging of the completely printed paper.

Abstract: The control system (1) exhibits a microprocessor (2) and a watchdog circuit (2); it is preferably used for controlling vehicle locking systems. The microprocessor (2) regularly carries out evaluations and is switched to stop mode for saving power in between times. As a result, accurate time measurements extending over a number of evaluating cycles can no longer be carried out by the microprocessor (2). The charging time of the watchdog (3) is measured and compared with its nominal charging time. Using the difference of the two, a trigger time with defined offset is specified to which the watchdog time is calibrated by the microprocessor (2). The calibration is repeated at regular time intervals. <IMAGE>

Abstract: The liquid coolant circulation control system for an immersion cooling system comprises a casing accommodating electronic circuits to be immersed in and cooled by a liquid coolant, a collecting pump for collecting the liquid coolant from the casing, first measuring means for measuring a flow rate of the liquid coolant flowing into the casing, and second measuring means interposed between the casing and the collecting pump for measuring a flow rate of the liquid coolant flowing out of the casing. Furthermore, determining means calculate the difference between the flow rates measured by the first and second measuring means, and control means control the operation of the collecting pump such that the difference determined by the determining means remains at a predetermined value. This liquid coolant circulation control system maintains the pressure acting on a liquid coolant and liquid passages constant and low to thereby promote nuclear boiling cooling. Thus, it enhances efficient cooling while implementing members defining the passages with low resistivity to pressure.

Abstract: A semiconductor optical device includes a semiconductor laser having an effective refractive index n c , a first film having a refractive index n₁ and a thickness d₁, a second film having a refractive index n₂ and a thickness d₂, and a third film having a refractive index n₃ and a thickness d₃. The first to third films are disposed on a facet of the semiconductor laser. In this structure, the refractive indices and thicknesses of the first to third films are determined to satisfy that a characteristic matrix Xa of the whole three films is equal to a characteristic matrix Y of a single film whose refractive index n f  is a square root of the effective refractive index n c  of the semiconductor laser and whose thickness is obtained by dividing an oscillation wavelength λ of the semiconductor laser by 4n f . Therefore, a non-reflection film having no reflectivity at the oscillation wavelength of the semiconductor laser is attained, and the production of the non-reflection film is simplified.

A maximum limit temperature Ts defines the maximum ironing temperature of fragile fabrics. In the case of maladjustment of the thermostat, the operation of the iron is cancelled. It is possible to make the functioning of the detector DNA dependent on a moisture detector (60) which measures resistivity of the fabric. The functioning of these detectors (35) (85) (60) may also be dependent on a detector of the use of the iron. <IMAGE>
