Abstract: The invention relates to packaging inserts made of folded cardboard strips, in which in each case one strip is cut out conically from the bottom and connected detachably to a further strip which is incised so as to widen from the top to the bottom. As can be seen in Figure 1, the base edges (6', 6") of the incisions next to the connection points (7', 7") with the side edges (5', 5") have a reduced spacing from the fold (4) if they are constructed on a first strip (1) and a reduced spacing from the base side (8) if they are constructed on a second strip (2). Additionally, the inserts are characterised in that the cardboard strips are provided on one or both sides with a lacquer which is impermeable to grease and/or water.

Abstract: To supply a frequency control signal to a laser diode module for generating a laser beam susceptible to a variation in frequency or wavelength, a frequency stabilizing device comprises a birefringent body (21) for converting the variation to a variation in a polarization state of the laser beam to produce a polarization varied beam, which a polarization separating element (22) separates into first and second beam components having orthogonally polarized directions and first and second beam intensities. Optical detectors (26,27) detect the beam intensities to produce first and second detection signals. A subtracter (28) calculates a difference between the beam intensities. A control signal producing arrangement (29) produces the frequency control signal in compliance with the difference. Preferably, the difference is normalized by a sum of the beam intensities. The birefringent body may be a uniaxial or a biaxial body. The uniaxial body should have an optic axis which forms an angle of 45° with a predetermined plane of polarization of the laser beam. In this event, the orthogonally polarized directions should be parallel and perpendicular to predetermined direction of polarization. It is possible to use the sum in stabilizing an output power of the laser diode module.

Abstract: L ightly  D epleted  P MOS (LDP) substrate-plate trench-capacitor (SPT) cell  A rray architecture is disclosed including three types of devices: An enhancement NMOS transistor (ENMOS) which has a n+ poly gate with a positive threshold voltage range, an enhancement PMOS transistor (EPMOS) having a p+ poly gate with a negative threshold voltage range, and a lightly depleted PMOS transistor (LDPMOS) (42, 44) having a p+ poly gate. The LDPMOS is used as the access transistor in the SPT cell with body biased at the power supply voltage VDD, and can also be used in the write drivers. A sense amplifier is included which is a CMOS cross-coupled latch (20, 22, 32, 34). An n-well is biased at a lower voltage than VDD, such as (VDD-Vg) where Vg is the silicon bandgap, and the lower thresholds enhance faster sensing. The CMOS cross-coupled latch is activated by turning on latching devices (50, 52). The bitlines are prevented from charging to greater than VDD-Vg, which could cause the array devices of unselected cells to conduct current and alter the stored low-voltage state of such cells.

Abstract: An optical fiber laser arrangement (10) includes an optical fiber section (11) that has a solid waveguiding portion capable of guiding light along a longitudinal axis between longitudinally spaced ends thereof. The waveguiding portion is at least in part of a material that emits light in response to stimulation by light. A pumping laser (12) is used to launch stimulating light into the waveguiding portion for longitudinal propagation therein. The waveguiding portion has at least one Bragg grating (13, 14) permanently embedded therein. The Bragg grating redirects light initially propagating in one direction into a different direction, and consists of a multitude of longitudinally consecutive grating elements constituted by periodic refractive index perturbations with a given periodicity that cumulatively cause light of a predetermined wavelength depending on the periodicity to change its direction of propagation from one of the directions to the other and to constructively interfere when propagating in the other direction.

Abstract: Magnetic start up inrush current to a ferro-transformer (305) of an off-line rectifier circuit is limited by controlling the phase angle of the input voltage (90 degrees for a single phase input and a standard three phase input) at which the input is connected to the ac source (300). 
     The input voltage to the off-line rectifier circuit is monitored for zero crossing points (312). In one arrangement the input voltage is directly monitored and a switch triggering pulse is time delayed for a time interval equal to 90 degrees of the input voltage waveform at which point the switch is enabled to connect the input AC voltage to the rectifier. In another arrangement the input voltage is integrated (311) and the zero crossing (312) of the waveform as integrated is used to define a trigger pulse to activate a switch (306) connecting the input voltage to the rectifier.

Abstract: An activation mechanism for an optical switch is disclosed. The mechanism is particularly suited for use with switches requiring the movement of a reflecting element into and out of an optical signal path to provide switching. The mechanism consists of a reflecting element (e.g., mirror (14)) and a means (18, 20) (e.g., magnetic, electrostatic, vacuum) for moving the reflecting element into and out of the optical signal path. In the absence of any applied signal, the reflecting element is positioned to intercept an optical signal and redirect it into the chosen output signal path. Upon the application of an external signal, the moving means will create a force of a strength sufficient to move the mirror and allow the optical signal to pass through the switch unobstructed by the reflecting element.

Abstract: The present invention relates to a method for characterizing a reservoir on the basis of rock and fluid flow properties, such as permeability and water saturation, from microscopic core measurements of formation samples. Information derived from core measurements of each hydraulic unit can be used to provide a transformation from wireline log porosity to permeability. The relationship between porosity and permeability is established by defining a hydraulic unit characterization factor, H c , the logarithm of which varies directly with the logarithm of porosity and the logarithm of permeability, although at a different magnitude with respect to each. The hydraulic unit characterization factor, H c , is the product of the square of the surface area of pore volume or grain volume and an effective zoning factor, K T , which accounts for variations in formation textural parameters that affect fluid flow.
