Abstract: A capillary stop-flow junction located in a housing at an end of a capillary passageway used to transport a liquid and at the beginning of a non-capillary internal chamber in the housing, in which the stop-flow junction contains an improvement which comprises 1) means for selectively trapping a gas in the capillary passageway and non-capillary chamber, wherein when the means for trapping is activated and the liquid enters the capillary passageway, the gas is compressed by the liquid as the liquid flows through the capillary channel and stops flowing at the stop-flow junction ; or 2) a stop-flow nozzle surrounding the capillary passageway and projecting into the chamber ; or 3) the stop-flow junction being formed from a single housing body member ; or 4) a rupture junction in the capillary pathway, wherein the rupture junction is a stop-flow junction providing less maximum available back pressure than the capillary stop-flow junction. Diluters capable of serial dilution that use the stop-flow junctions of the invention are also described.

Abstract: An apparatus and method are described for depositing a coating onto a substrate using vacuum arc evaporation from a substantially cylindrical cathode. An axial magnetic field is disclosed to force the motion of the arc into an open helical trajectory on the cathode surface. Means are also provided for controlling the speed and direction of the arc along the cathode by varying the division of input current between the ends of the cathode. Improved uniformity of cathode erosion and coating thickness are thereby achieved, along with a reduction in the number and size of splattered droplets incorporated into the coating.

Abstract: An improved method is provided for depositing a thin copper aluminum alloy film on a patterned silicon substrate. A copper base layer conforming to the existing pattern is initially formed on the surface of the substrate, followed by contact with vapors of an aminealane compound, which causes aluminum to be selectively deposited on the copper base layer portion of the substrate. Preferably, copper is applied to a diffusion barrier surface such as tungsten using chemical vapor deposition from a complex of copper (I) perfluoroalkyl-β-diketonate and an olefin or silylolefin. The entire process of developing an alloy film can be carried out without exceeding 200°C.

Abstract: A diffracting device consists of a substrate made of LiTaO₃, an optical waveguide extending in a central upper side of the substrate for transmitting 860 nm wavelength coherent light radiated from a semiconductor laser, a plurality of gratings periodically arranged on the optical waveguide at regular intervals, and a covering layer arranged on the gratings and the optical waveguide. The optical waveguide is formed according to a proton-exchange process. The gratings are made of photoresist material having a refractive index N1=1.5 and a high workability, and the gratings are uniformly formed according to an interference-exposure process. Therefore, the photoresist material is patterned without damaging the optical waveguide with reactive ions. The covering layer is made of Ta₂O₅ having a refractive index N2=2.0. Therefore, periodic change in the refractive index is generated in a periodic structure of the gratings and the covering layer, and a part of the coherent light is reflected by the periodic structure to fix the wavelength of the coherent light radiated from the semiconductor laser.

Abstract: In einer Oszillatorschaltung (VCOS) mit zumindest einem die Temperatur konstant haltenden Heizelement (HE) werden die gebildeten Taktsignale (ts) über eine Ausgangsverbindung (AV) an einen Ausgang (TA) der Oszillatorschaltung (VCOS) geführt. In diese Ausgangsverbindung (AV) ist eine Impedanzauswerteeinheit (WAE) eingefügt und derart ausgestaltet, daß eine Veränderung einer am Ausgang (TA) angeschlossenen Impedanz bzw. eines Widerstandes (R4, R5) erkannt und das Heizelement (HE) wirksam bzw. unwirksam gesteuert wird. Die Oszillaterschaltung (VCOS) hat den Vorteil, daß zur Wirksam-bzw. Unwirksamschaltung der Heizelemente auf eine separate Verbindung zwischen einer weiteverarbeitenden Einrichtung und der Oszillatorschaltung verzichtet werden kann und somit der Aufwand hinsichtlich Steckeinrichtungen und Verbindungsleitungen erheblich reduziert wird. <IMAGE>

Abstract: The invention relates to an operating-mode switch (function selector) for electrical appliances, especially electric cookers, which is arranged in a service panel accessible to the user. The purpose is to isolate the components in the appliance which are driven by high current and by low current. There is now only a low-current-driven control part of the operating-mode switch arranged in the service panel, whereas the true switching function, namely switching the energy supply to the loads (consumers), is carried out using a motor-driven component at another location on the appliance. The switching correlation between the control part and the switching part of the operating-mode switch is provided by two encoding switches, the pulses of which are checked in a comparator. As long as no agreement exists between the pulses of the encoding switches, the motor for the switching part is supplied with current and thereby turns cam discs and eccentric discs which switch the loads. <IMAGE>

Abstract: A method, based on resonant ultrasound spectroscopy (RUS), for determining flaws in objects or measuring Poisson's ratio (σ) and shear modulus (µ) is shown and described. First, the frequency for expected degenerate responses is determined for one or more input frequencies and then splitting of degenerate resonant modes are observed to identify the presence of flaws in the object. Poisson's ratio and the shear modulus can be determined by identification of resonances dependent only on the shear modulus, and then using that shear modulus to find Poisson's ratio using other modes dependent on both the shear modulus and Poisson's ratio. 
     In an apparatus for carrying out the method, a signal generator (14) excites a transducer (16) for vibrating object (12) over a predetermined freq. range eg 4-4000 kHz. The response of object (12) is detected by transducer (18) and supplied to output amplifier (22). The outputs from amplifier (22) are input to computer (24) for analysis and computation of the difference between the resonant vibrational modes of object (12) and those of an ideal object.

Title: Phase locking a disk drive spindle to a reference signal
Inventor: EVEN WILLIAM F
IPC: G11B19/28
Filed: 1994-04-25
Abstract: A disk drive in a multi-disk storage system has a spindle synchronizer and a spindle controller that are microprocessor-based. The spindle synchronizer has a counter used to track the phase of a master phase reference signal that is distributed to all the disk drives in the storage system. The counter may also optionally be used to generate the master reference signal. The spindle synchronizer also has programmable registers and a comparator that are used to generate a spindle reference signal having a programmable phase offset relative to the master reference signal, and a register used to sample the phase of the master reference once per revolution of its associated spindle. The spindle controller contains a counter used to measure the actual rotational period of the associated spindle. The spindle phase error is used in a phase correction algorithm that controls a reference voltage supplied to a motor spin controller. The algorithm employs frequency switching to phase-lock the associated spindle with the spindle reference signal generated by the spindle synchronizer.
