Title: Echtzeit-Kapillarrheometer-Anordnung
Inventor: GLEISSLE WOLFGANG DR-ING
IPC: G01N33/44
Filed: 1990-07-03
Abstract: Eine Kapillarrheometer-Anordnung zur kontinuierlichen und dis­kontinuierlichen Messung der Viskosität von unter konstantem oder variierendem Druck stehenden Substanzen (Meßflüssigkeiten), insbes. Polymerschmelzen oder anderen viskoelastischen Flüssig­keiten umfaßt ein Rheometer mit einer den Meßflüssigkeitsvolu­menstrom der Meßkapillare des Rheometers zufördernden Dosier­pumpe und eine Leitungsverbindung zwischen einer Flüssigkeits­probenahmestelle eines Reaktors, eines Extruders, eines Mischers, oder dergl. und der Dosierpumpe. Um eine derartige Anordnung zur Echtzeitmessung verwendbar zu machen, die sich unabhängig von den Gegebenheiten im Bereich der Probenahmestelle des Reaktors oder dergl. einsetzen läßt, und um einen großen Viskositätsbereich, insbes. auch während einer Reaktion, schnell genau abdecken zu können, sieht die Erfindung vor, daß zwei unabhängig voneinander einstellbare Fördereinrichtungen, nämlich eine Dosierfördereinrichtung und eine Zufuhrförderein­richtung für Meßflüssigkeit vorgesehen sind, von denen die Dosierfördereinrichtung der Dosierung des Meßflüssigkeitsstroms zur Meßkapillare dient und die der Meßkapillare vorgeschaltete Dopierpumpe umfaßt, und die Zufuhrfördervorrichtung eine Zufuhrpumpe aufweist, mit der Meßflüssigkeit der Dosierpumpe zugefördert wird. Dem bekannten Meßvolumenstrom wird so ein zweiter Flüssigkeitsstrom (Zufuhrstrom) überlagert, aus dem der Meßvolumenstrom möglichst nahe dem Rheometer abgezweigt wird. Der Zufuhrstrom ist unabhängig von der Größe des Meßvolumen­stroms und sorgt für einen schnellen Austausch der Meßflüssig­keit in den Zulaufkanälen zur Meßkapillare. Es werden mehrere unterschiedliche Anordnungen erläutert.

Abstract: Interferometric measuring systems are known. They contain a light source for generating coherent light, and an interferometer structure consisting of at least one beam splitter and two reflectors as well as lenses for focusing the light beam. According to the invention, such a measuring system serves for examining the frequency, modes, mode stability and mode distribution as well as coherence length and coherence time, etc. of a light bundle (30) transmitted from a laser light source (1). The light bundle (30) is rendered parallel by a lens, and subsequently passes to the reflectors (4, 5) in two component bundles (31, 32) via the beam splitter (3). One of the two component bundles traverses a reference interference pattern (7). The two component bundles (31, 32) interfere with one another and are fed via an optical system for reducing the numerical aperture to a photoreceiver (10). It is particularly advantageous if as many optical components as possible, in particular the lens (2), the beam splitter (3), the reflectors (4, 5) and the reference interference pattern (7), are monolithically integrated on one block (6). <IMAGE>

Abstract: When a control command signal is input to a sub-CPU (central processing unit) (2) from a main CPU (3) in a computer system, it is determined by a sub-CPU (2) that whether or not a control command included in the control command signal is an EEPROM (electridcally erasable programmable read only memory) control command. As a determination result, if the input control command is the EEPROM control command, a control command corre­sponding to the kind of the control command singal is provided to the EEPROM (1), the erase/read/write of data with respect to the EEPROM (1) is performed. If the input control command is not an EEPROM control command, then control of a keyboard (5) is executed.

Abstract: An exposure mask for lithography, a method of manufacturing the same, and an exposure method using the same are disclosed. A light-transmitting opening of the exposure mask has a main light-transmitting region located in the middle of the opening and having a first optical path length, and phase shift regions adjacent to a light-shielding layer and having a second optical path length, different from the first optical path length. Light transmitted through each phase shift region interferes with light transmitted through the main light-transmitting region at the edges of the light-­transmitting opening, thus enabling a sharp photo-­intensity distribution of total transmitted light to be obtained. As a result, the resolution of the exposure mask is improved.

Abstract: A logic analyzer stores the activity around the last in a series of triggering events while also storing the activity around several other triggering events immediately preceding the last trigger. The acquisition memory is first partitioned into a number, N, of memory sections and the trigger condition of interest is defined. Then repeated acquisitions are performed using this same trigger condition. At first, data from each of these acquisitions is stored in each one of the number of memory sections. When all of the memory sections have been filled once, if the trigger condition is still occurring, the acquisition memories are reused in the same order in which they were originally used as many times as necessary until it is ascertained that the trigger condition is no longer occurring or some external condition has changed, at which time the logic analyzer is stopped. One of the memory sections then contains the data that occurred in the vicinity of the last trigger. Another of the memory sections contains data reflecting the activity that immediately preceded the stopping of the logic analyzer. The remaining N-2 memory sections contain data that occurred in the vicinity of the triggers that immediately preceded the last trigger. Timestamping the acquired data allows the timing relationships involved to be reconstructed.

Abstract: The vehicle wheel 5 is driven by engine 3 through a continuously variable transmission 1 having a speed ratio e and consisting of a variable-displacement hydraulic pump 4 and a hydraulic motor 6. In an engine-braking mode the speed ratio e is controlled in dependence on vehicle speed V, sensed by sensor 10, and the angular position α of the accelerator pedal 2 as sensed by sensor 9. The initial range of travel of the accelerator is used for effecting engine braking and in one embodiment this is a range in which the throttle does not begin to open. The offset α from the position where the throttle begins to open is then used to control the ratio e. In another embodiment the ratio e is controlled by the angular position ϑ of the accelerator as long as this is to one side of a reference position and as the speed of the vehicle increases the degree of engine-braking which can be used is increased.

Abstract: The invention concerns a method and a device for tightening threaded joints in two subsequent steps, namely a first step during which a joint is tightened to a predetermined torque snug level and a second step during which the joint is further tightened up to a final predetermined pretension level. During the second tightening step the torque delivered by the power tool (10) comprised in the device is gradually increased at a rate exceeding the highest torque rate expected from the joint to be tightened. The power tool (10) comprises an electric brushless AC-motor which is supplied with power from a variable frequency output inverter (11), and the gradual increase in output torque from the power tool (10) is accomplished by the phase lag in the AC-motor as a result of a gradually increased output frequency from the power supply means (11).

Abstract: The alignment system comprises an optical unit (O.U.) with a dark-field/bright-field microscope and a device for detecting the light intensity. A reference mask pattern is projected onto structural edges (K) of the mask (11) and the wafer (W), said structural edges lying in parallel planes. The light scattered from the edges is detected via the dark-field beam path and the focus of the optical unit is mechanically shifted by means of piezo drives (P x ,P y ,P z ) between the mask plane and the wafer plane (z-direction), and in the x-y-plane for capturing the mask and wafer patterns. The advantages of the invention reside in a simpler and less expensive manufacture of the alignment system, a more accurate alignment and a larger capture area for the mask and the wafer patterns.

Abstract: Pins of an IC under test are classified into pin groups according to the delay time to be set for a test clock for each pin, and a table of pin group data, which has, at a bit position corresponding to each pin, a "1" or "0" which indicates whether the pin belongs to each pin group, is stored in a pin group table memory (24). The bit positions of the logical values "1", indicating that the pins belong to the pin group, in each pin group data read out from the pin group table memory are sequentially encoded by a priority encoder (26) in an ascending (or descending) order and the delay data is provided to a delay data memory (23). The delay time data common to all the pins belonging to the pin group provided from a tester processor (10) is written into sequentially specified addresses, by which the delay time data for all of the pins can be written into the delay data memory from the tester processor in a short time.

Abstract: An external position detector (6) is mounted on a head arm (1) that also carries a transducer (2) for tracking a magnetic disk (5). When the head arm (1) is moved at constant speed, the position detector (6) produces an output signal that is periodic but has a measurable pitch error or pitch uneveness. The periodic output signal is measured to determine the pitch error, and an amount of compensation required to compensate for the measured pitch error is calculated. A value of the periodic output signal corresponding to the amount of compensation and therefore corresponding to an absence of pitch error is calculated, and a servo signal is recorded on the magnetic disk (5) at a location corresponding to the calculated value of the periodic output signal. The pitch error is thereby fully compensated, and the servo signal is recorded with precision.

IPC: B66B1/28

Abstract: Start jerk and acceleration overshoot on elevator starting are reduced by bypassing and delaying application of an elevator closed loop velocity control system. A bypassing starting torque increases the torque of the motor before the onset of motion, at which time the starting torque is leveled off and held constant and the velocity speed reference profile is started. A small creep velocity dictation injected into the closed velocity loop in addition to the starting torque command causes the difference between the speed profile and the sensed speed to be very small during starting. Moreover, by selecting lift brake current in such a way as to promote a smooth brake opening and by selecting an increasing starting torque profile which overcomes the declining brake torque just after the brake begins to open, the torque needed to compensate for the load can be evenly balanced with the release of brake torque. The timing of initiation of the starting torque may be selected according to a time delay which may vary between different installations and be adjustable in order to obtain zero rollback when the elevator car first moves. A step decrease in the starting torque may be dictated upon detecting system movement in order to compensate for the transition from static friction to sliding friction. The rate of increase of starting torque is preferably exponential.
