Abstract: A low-loss optical 1 x 2 branching element comprises a symmetrical coupler (Cs) with a symmetrical power distribution (1/2 /1/2 ) and an asymmetric coupler (Ca)with an asymmetric power distribution (ä(1/2 - x)/(1/2  + x)ü). Outputs (c,d) of the symmetrical coupler are coupled to inputs (e,f) of the asymmetric coupler, so that an MZ interferometer with two branches (t1,t2) is formed between the two couplers. The branches incorporate, preferably identical, optical non-linear elements (NL1,NL2), while moreover the branches exhibit an additional difference in linear optical path length ( DELTA L) that depends on the type of couplers selected. In one signal direction (arrow D) the branching element acts as a 3 dB splitter. The elements (NL1,NL2) and the coupler (Ca) have been dimensioned so as to result in a loss << 3 dB for a given signal power in the other signal direction (arrow U). <IMAGE>

Abstract: A feed wheel (72) advances a release liner supporting the labels. A brake (96) prevents movement of the label stock (35) during application of a label. A ratchet (94) and pawl (92) arrangement incrementally advances the feed wheel each time a hand lever (54) is returned to its rest position.

The feed and brake release ratchets are preferably integrally connected to opposite sides of the feed wheel. Mechanisms are also provided for ensuring removal of the brake prior to incremental label stock advancement and for manually iatching the brake in its released position during loading of label stock in the apparatus.

Abstract: A method of and a system for controlling an inverse kinematics generated animation of an articulated chain is described. A resolution plane in a default orientation is computed by determining a root-effector vector extending from a root of an articulated chain to an end effector of the articulated chain and letting the resolution plane extend through the root-effector vector. A control icon representative of a position relative to the root is visually displayed. The resolution plane of an articulated chain is manipulated by manipulating the icon and re-determining the resolution plane using the root-effector vector and a root-control vector extending from the root to the icon. The animation of the articulated chain is constrained relative to the resolution plane and a solution of positions and orientations of all limbs of the articulated chain in achieving a goal is computed and displayed.

According to the electronic device of the present invention, a rectangular-shaped heat sink that absorbs heat of the CPU and is placed in a cooling air intake channel (71) upstream of the power source unit. By blowing low-temperature cooling air that does not contain heat radiating from the power source unit onto the rectangular heat sink, the rectangular heat sink is cooled, and CPU heat dissipation is promoted. In this way, the CPU can be efficiently cooled so that the electronic device can be made smaller than conventional devices of the foregoing type.

Abstract: PURPOSE:To obtain an electric double layer capacitor having a small size and a large capacity by using powdered active charcoal containing 20wt.% to less than 35wt.% of oxygen. CONSTITUTION:In an electric double layer capacitor having mixture of powdered active charcoal and electrolyte solution as polarizable electrodes, powdered charcoal containing 20wt.% to less than 35wt.% of oxygen content is used as powdered active charcoal 1 in a base element 8. That is, the oxygen in the charcoal is not contained in a carbon skeleton, but exists in a surface functional group state, and the functional group containing the oxygen contributes to an increase in an electric double layer capacity. Thus, an electric double layer capacitor having a small size and a large capacity is obtained.

Abstract: A secure data storage system for a computer has a data storage system with a data interface to the computer mounted on a heat sink structure within a fireproof enclosure. A heat transfer system connected to the heat sink structure and to a wall of the fireproof enclosure transfers heat from the heat sink structure to outside the fireproof enclosure. A thermostat controller mounted outside the fireproof enclosure, upon detecting a temperature indicating of a fire, causes the heat transfer system to cease transferring heat from inside the fireproof enclosure to outside the fireproof enclosure and blocks passage of heat from outside the fireproof enclosure to inside the fireproof enclosure via the heat transfer system. Both passive and active heat transfer systems are disclosed. In another aspect of the invention, security for entered passwords is provided by diverting password keystrokes from a keyboard to a special controller, bypassing the keyboard controller. In one embodiment the special controller is also a read/write controller simulating an interface to a local hard disk, but in reality transferring data to be stored via a data link to the data storage unit in the fireproof enclosure.

The characterizing feature of the process is that (a) carbonate ions and/or hydrogen carbonate ions (CO32- or resp. HCOe- ) are supplied to the aqueous medium, and (b) the pH in the aqueous medium is adjusted to an alkaline value so that calcium carbonate precipitates and forms part of the suspension. There are overall major advantages provided by the process in the context of applying gypsum coatings on paper, inasmuch as broke can be reused in the process without any troublesome gypsum precipitation. Moreover a new grade of coated paper is described, the characterizing feature of this paper being that the filler of the base paper consists entirely or partly of precipitated calcium carbonate (PCC) and that the pigment of the coating layer consists entirely or partly of calcium sulfate.

Abstract: Improved performance is obtained in computers of the type having vector registers which communicate with one or more functional units and common memory. As elements of a vector are read from a vector register for transmission to common memory or as operands to a functional unit, the vector register immediately becomes available to receive and store elements of a vector from common memory or a functional unit. The element-by-element storing takes place simultaneously with the element-by-element reading, and trails the reading by at least one element so as to not overwrite elements yet to be read. Through the use of this technique a vector register can be loaded with a vector for a subsequent operation without having to wait for the completion of the previous operation which uses the same vector register.

Abstract: Motor vehicle wheels are often damaged because the driver contacts the kerb with the outer side of the wheel during parking. On contacting the kerb, the tyre, which generally protects the vehicle owing to its greater width, is often so greatly distorted that the outside of the wheel rim is crushed against the kerb and is thereby damaged. A motor vehicle wheel (11) is produced with an annular device (13) which at least partly covered the visible side of the wheel rim (18). As the joint between the annular device (13) and the wheel is releasable, the annular device (13) can be easily changed after suffering damage and the wheel (11) once more looks as good as a new.

Date Mar. 28, 1996The invention provides a process and apparatus for the detection of obstacles by means of ultrasound waves having an enhanced ability to distinguish between echoes caused by obstacles and those caused by interference signals. Ultrasound pulses are emitted by an ultrasound transmitter unit, and are received by an associated ultrasound receiver unit. (A plurality of such transmitters and receives may also be used.) Ultrasound echoes detected by the receiver units are used to form echograms in which detected echoes are projected. The echogram thus measured is used to generate an analysis echogram, based on information contained in the measured echograms. In particular, the most recent analysis echogram is modified depending on the size and location of echoes contained in the measured echogram. Signals contained in the analysis echogram are then compared with predetermined threshold values to distinguish between echoes reflected from obstacles and echoes due to interference.
