Abstract: A plastic film having a random embossed matte finish is provided. The random embossed matte film may be wound very easily into rolls and the roll contour achieved has superior uniformity. In addition, the film provides relatively equal tape adhesion and gloss properties on both sides which make it especially suitable for use in articles such as disposable diapers or underpads. Another advantageous property which renders it especially suitable for diaper conversion operations is its very low degree of edge curl. The thin film provides a totally different appearance as compared to conventional diaper films in that the overall appearance is a dull matte finish, but nonetheless having slight sparkles of brilliance throughout the surface, and it further provides a softer feel.

Abstract: This invention relates to a polarization-independent optoelectronic directional coupler. A wafer (11) e.g. of lithium niobate has light waveguides (13) at its upper surface (12). There are main electrodes (17) and secondary electrodes (18) along the interaction length (L1) of the light waveguides. The wafer is oriented in relation to its crystalline structure (X,Y,Z) such that its optical axis (Z) is in a plane at right angles to the upper surface (12) and contains the longitudinal direction of the waveguides (13). The optical axis (Z) deviates here an angle ( beta ) of at most 15 degrees from the upper surface (12), and the X axis may have six symmetrically distributed positions, of which one is in the plane of the upper surface (12). Independent of the polarization state of a light beam, this beam entering at an input (14) can be switched in its entirety to either of the outputs (15) of the coupler. With the aid of the secondary electrodes (18) an electrical field through the waveguides can be directed at right angles to the upper surface (12). With the stated orientation of the wafer, the refractive index of the material can be changed hereby so that the desired switching is obtained. The light propagation in the direction of the optical axis (Z) permits high pulse frequency.

At least specific contacts are doubled, and provided with monitors which, when there is lack of uniformity in the functions of such doubled contacts, maintain the robot in a safe situation. The action of the safety components in putting the robot in a safe position is to switch off energy feed to its drive motor. - The contacts are arranged in several chains, where each chain is connected to a voltage source and comprises one or more series-coupled contacts and a component connected to the voltage source via the contacts. When any of the contacts break, this component puts the robot in a safe situation. Each safety stipulation activates a contact in each chain. A monitor probes the voltages fed to the components which cut out the drive of the robot motor. Certain of the contacts used ae relays.
