Patent EP-0308522-A1 (EP)
Inventor: VLAKANCIC CONNOR G
IPC: G04G21/02
Filed: 1987-09-19
Abstract: An altimeter device employs a solid state pressure sensor having a strain-sensitive element directly in a silicon diaphragm, which is connected at one side to a closed vacuum chamber. The entire device is very compact and may be in the form of a wristwatch. A display indicates altitude or relative altitude above or below a reference point to the user, and electronics associated with the device provide for accumulation of vertical change in one direction, regardless of intervening changes in the opposite direction. In this way, a skier, hiker or biker, for example, may determine total vertical drop or vertical rise encountered in a selected period, without regard to offset from movements in the opposite direction. At the same time, the user may also determine his altitude at any given point, and in a preferred form the altimeter device includes a clock and a time-averaging feature, for calculating and displaying rate of climb or descent, both instantaneous and average over a selected interval. The device may also have a time display, so that it functions as a wristwatch as well as an altimeter, and a synthesized voice output may be included for reporting data to the user's ear when visual observation of the display is not practical.

Abstract: Zur Untersuchung eines Meßmediums (2), insbesondere Blut, dient ein Meßkanal (12), der mit einem Meßsensor (10) und einem Referenzsensor (11) versehen ist und der mit dem inneren Lumen (6) eines Katheters (4) verbunden ist. Das äußere Lumen (5) des Katheters (4) wird mit Infusionslösung (16) versorgt. Beide Lumen (5, 6) haben eine gemeinsame Mündung (8) zum Meßmedium (2). Durch wiederholte Umkehrung der Strömungsrichtungen in den Lumen (5, 6) mittels einer umsteuerbaren Pumpe (15) wird eine Folge von jeweils abwechselnd gleichen Raumteilen des Meßmediums (2) und der Infusionslösung über die Sensoren (10, 11) gezogen. Damit erhält man eine besonders einfache und wirksame Meßanordnung zur Blutuntersuchung, bei der Driftprobleme und Toxizitätsprobleme nicht auftreten können und die keine elektrochemische Bezugselektrode benötigt.

Abstract: A device for reciprocally interlocking two parallel switch axes (1, 2) is published. In a known arrangement, the interlocking of the switch axes must be carried out by manual movement of a slide. In the arrangement which is now being published, the interlocking takes place automatically on each switching operation. A locking member (4, 5) is mounted on each switch axis (1, 2), which locking member (4, 5) engages in a square recess (6, 7) of a slide (3). Two side edges of each recess (6, 7) run parallel to the slide longitudinal axis, which is located in a straight line connecting the two switch axes (1, 2). The perimeter of the locking members (4, 5) is identical to the respective inner perimeters of the recesses (6, 7). The locking members (4, 5) are arranged such that one is always located centrally in the inner perimeter of the associated recess (6, 7), while the other is located on a side edge of the associated recess (6, 7) running at right angles to the slide longitudinal axis. <IMAGE>

Abstract: A high speed low power linear two micron CMOS full differential operational amplifier has a pair of output cascode stages (44, 45) each providing a respective differential output with rejected common mode signals. The amplifier comprises an input differential amplifier stage (72) driving a pair feedback current mirror loads (18, 20) each cross connected to the pair of cascode output stages providing the differential outputs. Current domain operation provided by current mirror arrangements (34,35) enables fast operation of the full differential amplifier. Each output cascode stage comprises four stacked transistors including two signal transistors and two dynamically biased pass transistors. The feedback current mirror loads (18,20) and the cascode output stages (44, 45) provide the amplifier with single gain stage respecting each differential output thereby reducing the need for large compensation capacitors while improving the dynamic range of the two differential outputs. The gain of amplifier is ninety decibels with a frequency bandwidth of fifth megahertz and with low power dissipation at two milliwatts. The amplifier also comprises two feedback differential stages (62, 64) receiving a single combined common mode signal (60) formed the two differential outputs. Each feedback differential stages then drives a respective pair feedback current mirror loads (78,80,82,84) which provide negative feedback signals to the output cascode stages (44, 45) whereby common mode signals are rejected at the differential outputs.

Abstract: This invention describes a pulsed plasma pinch x-ray source. In the device the initial plasma annulus (25, 27) is derived from an electrical gas discharge in a chamber (12) having constricted openings (16, 18) arranged on a circle. This low mass plasma annulus is imploded and pinched (34) by passing high current axially through said annulus. The hot and dense pinched plasma copiously emits x-rays and has the capability of being fired at high repetition rates. The device is simple for commercial applications, such as x-ray lithography.

Abstract: A tape reel structure for a tape cassette provides radially extending ribs (21) between an outer cylindrical section forming tape reel section (11) which is to have wound therearound a tape, and an inner cylindrical section (12) serving as a reel shaft boss. The ribs (21) at least have a portion extending substantially through overall length of the outer cylindrical section (11) so as to prevent radially inward deformation thereof. The ribs (21) join with the inner cylindrical section (12) at the radially inner edges. The upper end of the joining portion between the inner edge of the rib and the inner cylindrical section is at a lower elevation that the upper end of the joining portion between the outer edge of the rib and the outer cylindrical section. This height difference is effective for preventing the outer cylindrical section from forming wave-form uneveness during moulding process. The ribs extending substantially the overall length of the outer cylindrical section successfully prevents the outer cylindrical section from radially inward bending.

Abstract: The universal-joint shaft included in the propulsion system is used for measuring these operating characteristics. Here, the torsional angle of the two ends of the universal-joint shaft relative to one another is a measure of the load moment occurring in each case. This load moment is used for analysing in an analysing unit in comparison with the permissible torsional angle or load moment for triggering various impulses, for example for indicating the overload case, or for triggering switching pulses for reducing the torsional angle. Improved utilisation of the entire propulsion line and the output capacity of the propulsion system of the vehicle is thereby possible.   <IMAGE>

Abstract: The invention relates to a process for manufacturing an integrated semiconductor structure having devices with dimensions in the submicrometre region, in which a three-layer resist system is used for producing a polymer or resist mask. The resulting polymer or resist mask is used to etch a layer, for example a polysilicon layer, on the semiconductor substrate. The process is characterised in that the pattern (6), which has been produced in the upper layer of the three-layer resist in conventional manner and which contains an angle of < 90 DEG , is transferred by RIE with CF4 into the plasma nitride centre layer (5) and by RIE with oxygen into the lower resist or polymer layer (4). According to the invention, the plasma nitride mask (5) is first removed, a facetting step is optionally carried out in oxygen to reinforce the positive angle in the mask structure (4) and only then is a lateral etching of the mask structure (4) carried out in oxygen in order to obtain the desired reduction in the dimensions of the mask.

Abstract: CD players in which such a device can be moved up and down in the manner of an elevator, for example by means of a drive comprising a spindle, a rack and gearwheels, or a slotted link on each side, are known. It is disadvantageous that many expensive small parts are required, such as for example gearwheels, spindles, worm wheels, racks, slotted links etc., which not only take up considerable space but also cause disturbing noises during operation. In order to reduce the expenditure on components, at the same time save space and reduce the disturbing noises, a drive is provided only on one side of the device (6), whereas on the side opposite the drive there is provided a spring (3) for supporting the device (6).
