A padlock includes a lock body, a shackle, and a sleeve. The lock body includes opposed front and rear longitudinally extending side walls terminating at first and second end portions. The shackle extends from the first end portion of the lock body. The sleeve covers at least a portion of each of the longitudinally extending side walls, and an internal surface of the sleeve includes at least one longitudinally extending rib contacting at least one of the front and rear longitudinally extending side walls to define a gap between the sleeve and the lock body.

A SAW element of the present invention includes a plurality of inter-digital transducer (IDT) electrodes on a piezoelectric substrate, grating reflector electrodes disposed on the sides of the IDT electrodes, and a plurality of pad electrodes led from the IDT electrodes and the grating reflector electrodes. A plurality of the pad electrodes includes isolated pad electrodes not directly opposed to the outer periphery of the SAW element, and adjacent pad electrodes directly opposed to the outer periphery thereof. A connecting electrode between the isolated pad electrode and the adjacent pad electrode is removed by etching at least before dicing in order to prevent discharge from occurring due to pyroelectricity, and to prevent the electrodes from being damaged.

A sensor utilizing a non-leachable or diffusible redox mediator is described. The sensor includes a sample chamber to hold a sample in electrolytic contact with a working electrode, and in at least some instances, the sensor also contains a non-leachable or a diffusible second electron transfer agent. The sensor and/or the methods used produce a sensor signal in response to the analyte that can be distinguished from a background signal caused by the mediator. The invention can be used to determine the concentration of a biomolecule, such as glucose or lactate, in a biological fluid, such as blood or serum, using techniques such as coulometry, amperometry, and potentiometry. An enzyme capable of catalyzing the electrooxidation or electroreduction of the biomolecule is typically provided as a second electron transfer agent.

Um eine Vorrichtung zum Herstellen von Dichtungslagen (144) für ein- oder mehrlagige Dichtungen (142) aus jeweils einem Dichtungslagenabschnitt (124') eines mehrere zusammenhängende Dichtungslagenabschnitte umfassenden Ausgangsmaterials, umfassend ein Folgeverbundwerkzeug (114) mit mehreren längs einer Vorschubrichtung (108) aufeinanderfolgenden Bearbeitungsstationen (122), in welchen die Dichtungslagenabschnitte während Arbeitstakten bearbeitet werden, wobei mindestens eine der Bearbeitungsstationen als eine Außenkonturlinien-Schneidstation ausgebildet ist, in welcher mittels eines Außenkonturlinien-Schneidwerkzeugs einander zugewandte Außenkonturlinien (147) zweier einander benachbarter Dichtungslagen geschnitten werden, und eine Vorschubvorrichtung (106), durch welche die Dichtungslagenabschnitte zwischen zwei Arbeitstakten um eine Vorschubstrecke v längs der Vorschubrichtung weiterbewegt werden, zu schaffen, bei welcher die Außenkonturlinien der Dichtungslagen mit geringerem Aufwand geschnitten werden und das Ausgangsmaterial besser verwertet werden kann, wird vorgeschlagen, daß das Außenkonturlinien-Schneidwerkzeug so ausgebildet ist, daß die Außenkonturlinien der beiden einander benachbarten Dichtungslagen mit derselben Schneidkante geschnitten werden, und daß die Vorschubstrecke v im wesentlichen gleich groß ist wie die Ausdehnung b der Außenkontur einer fertigen Dichtungslage oder einer Gruppe (158) von fertigen Dichtungslagen längs der Vorschubrichtung.
摘要:
The present invention relates to a method for producing a plurality of piezoelectric actuators (1), wherein said method comprises the steps of: producing films (10) made of a piezoelectric ceramic material; covering one surface at least of the films (10) with electrodes (3); piling up and compressing the films (10) into a stack; sintering the stacked films (10); and separating the stack into individual actuators (1). When the films are stacked, the cavities (11) of said films (10) are accurately aligned on each other.
