Abstract: In einem Vermittlungssystem, insbesondere Paketvermittlungssystem, kann die Flußsteuerung der Pakete mittels Datagramm oder unter Verwendung des Verfahrens der virtuellen Verbindung erfolgen. Bei der Optimierung der Flußsteuerung ist der gewählte Aufbau des Koppelfeldes von besonderer Bedeutung. Soll das Koppelfeld nach Art eines Raum-Multiplex-Koppelfeldes aufgebaut werden, so ist jedem Koppelpunkt des aus Zubringer- und Abnehmerleitungen aufgebauten Sammelschienensystems ein Komparator zugeordnet, welcher die Adressen der spaltenweise angeordneten Abnehmerleitungen mit der Weglenkungs-Information im Nachrichtenkopf der Pakete vergleicht. Sollen gleichzeitig mehrere der zeilenweise angeordneten Zubringerleitungen zu einer der spaltenweise angeordneten Abnehmerleitungen durchgeschaltet werden, so wird die Reihenfolge mittels einer jeder Abnehmerleitung zugeordneten Entscheiderschaltung festgelegt. Wird die Reihenfolge durch die räumliche Anordnung der Zubringerleitungen bestimmt, so fragt jede Entscheiderschaltung alle ihr zugeordneten Komparatoren zyklisch ab, sodaß erst nach Abarbeitung des gesamten Zyklus eine neue Auswertung der Weglenkungsinformation erfolgt.

Abstract: A dual function disposable absorbent insert (10) having an absorbent element (11) and a removable liquid impervious backsheet (30) is provided. Upon removal of the backsheet (30), the absorbent element (11) retains structural integrity and allows liquids to pass clear through. In a preferred embodiment, the insert (10) comprises (from the body contacting layer down): a liquid permeable topsheet (15), an absorbent core (20), a liquid permeable bottomsheet (25), and a liquid impermeable backsheet (30). The backsheet (30) is removable. In its four-layer form the insert (10) can be placed in a user's underpants to provide both absorption and containment of body exudates. With the backsheet (30) removed and with the insert (10) in its three layer form, the insert (10) is intended to be used as a secondary absorbent structure which is placed inside of a primary absorbent structure such as a diaper or brief. In this form the insert (10) acts as an absorbent booster for the primary absorbent structure by providing quick acquisition of liquid gushes and greater total absorbency.

Abstract: A conceptual design tool uses a sketch sheet approach on a computer display to enter the functional design of a product, thereby encouraging the designer to use a top down approach to the design process. The user keys in part descriptions, and the system automatically draws a hierarchical tree structure on the computer display. The user is then prompted to consider, part by part, all of the parts in the product. A series of pop-up menus guide the user through manufacturing and planning for the part. Based on the data input by the user, the system then generates a qualified parts list and computes an estimated cost figure for the product using manufacturing information gathered by the conceptual design tool during product release planning.

Abstract: A titanium oxide-coated chromatic-color metal flake pigment is prepared by hydrolyzing an oganic titanate ester compound, e.g., tetraisopropoxy titanium, in the presence of the base metal flakes suspended in an organic medium having a pH of 4 to 8. The pigment exhibits iridescent color tones of great aesthetic value delicately varying depending on the thickness of the titanium oxide coating layer. The pigment has high chemical stability, for example, against acids, by virtue of the very uniform and dense coating layer of titanium oxide so that the inventive pigment is useful as a coloring agent in a water-borne composition. Application fields of the inventive pigment include colored coating compositions, ink compositions, cosmetic preparations, molding compounds of plastic resins and so on.

Abstract: In a fingerprint processing system for use in detecting a core position of a fingerprint image quantized into a plurality of picture elements, statistical processing is carried out in relation to parameters which are variable in dependency upon the core position and directions and curvatures of the picture elements preliminarily detected to specify ridges of the fingerprint image. The parameters may be existence probabilities of the core position that are determined for the directions and the curvatures. Such existence probabilities are successively calculated at each picture element and adjacent picture elements to be summed up and to detect a maximum one of the existence probabilities. A position which has the maximum existence probability is judged as the core position. Alternatively, the parameters may be differences between practical curvatures extracted from the fingerprint image and reference curvatures defining a reference curve. A minimum one of the differences is statistically detected with reference to various kinds of the reference curves. In addition, the directions and the curvatures of the picture elements may be determined by deriving the density levels of the picture elements along a plurality of arcuate lines specified by line directions and line curvatures.

Abstract: A fluid controller (17) is disclosed for controlling the flow of fluid to a steering cylinder (19). The controller includes a fluid meter (51) and a valving arrangement (49) including a valve spool (65) and a sleeve (67), which define a main fluid path including a main variable flow control orifice (121), the fluid meter (51), a variable flow control orifice (123), the steering cylinder (19), and a variable flow control orifice (125). In accordance with the invention, the spool and sleeve define an amplification fluid path including a variable amplification orifice (129) in parallel with the main fluid path, and disposed to amplify the flow of fluid through the meter. In one embodiment of the invention, the amplification fluid path communicates with the main fluid path upstream of the main variable flow control orifice, and at a location downstream of the fluid meter, but upstream of the variable flow control orifice (123). In order to facilitate manual steering using the fluid controller of the invention, the amplification orifice (129) reaches its maximum flow area when the spool and sleeve are still several degrees away from their maximum displacement. The amplification orifice then decreases and closes as the spool and sleeve reach maximum displacement. As a result, the amplification fluid path is closed at maximum valve displacement, and therefore does not act as a short-circuit, making it impossible to manually steer.

Abstract: A first input section inputs a first signal (S) serving as a trigger. A second input section inputs second and third signals (C1, C3) having phases opposite to each other to set a time period width. A first data hold section (1) obtains a first hold output in response to the first and second signals (S, C1) respectively output from the first and second input sections. A second data hold section (2) obtains a second hold output in response to the first and third (S, C3) signals respectively output from the first and second input sections. A determination section (3, 8, 9) determines whether the first hold output from the first data hold section (1) or the second hold output from the second data hold section (2) is output first. A selec­tion section (11) selects the second or third signal (C1, C3) from the second input section in accordance with a determination result from the determination section (3, 8, 9). A counter (7) counts the second or third signal (C2) selected by the selection section (11) to set a time period width of a pulse signal (P) to be output, and generates the pulse signal (P) to be output at a predetermined timing in response to the first and second hold outputs respectively output from the first and second data hold sections (1, 2).
