Abstract: For measuring a phase difference ( phi ) between an actual pulse (A) and a reference pulse (B), the actual pulse (A) is applied to the input terminal (3) of a delay chain (2) having a multiplicity of delay elements (1). The actual pulse (A) enters the delay chain (2) and is held there as determined by a control signal (S) derived from the reference pulse (B). The actual pulse (A) is subsequently shifted out of the delay chain (2), under clock control, the number of delay elements (2) still to be passed determining the phase difference ( phi ). In a circuit arrangement for measuring such small phase differences, the series circuit of a load path of a first transistor (5) of a first inverter (6), a load path of a second transistor (7) and a second inverter (8) are arranged between an input terminal (3) and an output terminal (4) of each delay element (1), the control connections of the first and second transistors (5, 7) being connected to a control device (9). <IMAGE>

Abstract: A sputtering cathode for the coating of substrates. The cathode has a base, a target of nonmagnetic material, and a magnet system having exposed pole faces for the production of a tunnel of magnetic lines of force overarching the sputtering surface. The target is provided with at least two continuous projections lying one inside the other, which contain at least one sputtering surface between them, and have confronting wall surfaces. The pole faces are located on both sides of the projections and sputtering surface between them such that magnetic lines of force issue perpendicularly from the one wall surface and, after crossing the sputtering surface, re-enter perpendicularly the opposite wall surface. The magnet system has permanent magnets magnetized parallel to the projections, which are yoked together on the sides facing away from the projections by a soft-magnetic base, and are provided on the sides facing the projections with soft-magnetic pole shoes extending over at least a part of the height of the projections.

Abstract: PROBLEM TO BE SOLVED: To improve visibility of a flipper button in the dark. SOLUTION: A key operation part is provided on the surface part of a main body, and a backlight for illuminating the key operation part from the inside is installed. The main body is provided with a flipper which covers the surface part so that it can be opened and closed. The flipper is provided with, for example, a semitransparent flipper button so that an incoming response and end keys can be operated in the key operation part with the flipper closed. The main body is provided with an open/close detection switch which detects the open/close state of the flipper.  When a backlight lighting conditions are realized (S1: Y) and the close state of the flipper is detected by the open/close detection switch (S3: Y), a control circuit performs such control (S5) that the light quantity of part of LEDs constituting the back light and corresponding to the flipper button is made larger than normal (S4). Thus, the backlight light is transmitted to brighten the flipper button.

Abstract: A device and method for separating heavier and lighter fractions of a fluid sample. The device includes a plurality, of constituents comprising a container and a composite element in the container. The composite element is a separator comprising at least two components and more particularly, a bellows with a seal body, a low-density float and a high-density ballast. A fluid sample is delivered to the container and the device is subjected to centrifugation whereby the centrifugal load causes the seal body of the separator to deform so that the separator migrates through the fluid sample and then stabilizes between the heavier and lighter fractions of the fluid sample. The seal body of the separator will resiliently return to its initial configuration upon termination of the centrifugal load such that the seal body sealingly engages the container and the composite element separates the heavier and lighter fractions of the fluid sample. <IMAGE>

Abstract: A unitary disposable absorbent article, particularly a catamenial pad or incontinent pad, having stabilizer members along the longitudinal side edges to enable the pad to assume a configuration conforming closely to the perineal area of the human body thereby more readily intercepting bodily discharges and providing a barrier to side soiling. The absorbent articles of the present invention comprise a central absorbent panel; a pair of side wall panels extending outwardly from and along the side borders of the central absorbent panel; and an axis of flexural bending joining each side wall panel to the central absorbent panel. The absorbent articles are constructed of a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, an absorbent core positioned between the topsheet and the backsheet, side flaps extending outwardly from and along the side edges of the absorbent core, and stabilizer members joined in the side wall panels with the laterally innermost edge of the stabilizer member being disposed at or laterally inward from the side edge of the absorbent core. Thus, the stabilizer members increase the flexural stiffness of the side wall panels so that the flexural stiffness of each side wall panel is greater than the flexural stiffness of the central absorbent panel of the absorbent article. The lateral compression of the side wall panels is also greater than the lateral compression of the central absorbent panel to allow the central absorbent panel to buckle and bend upward to conform to the body. Preferably, the stabilizer members are joined to the wearer's surface of the topsheet to further provide a barrier to the lateral flow of liquids along the top surface of the absorbent article.
