Abstract: A thin film SAW device comprises a carrier substrate (CA), a TCF compensating layer (CL), a piezoelectric layer (PL), and an IDT electrode (EL) on top of the piezoelectric layer. A functional layer (FL) is arranged between piezoelectric layer and TCF compensating layer to further reduce the TCF. The material properties of the functional layer match those of the piezoelectric layer in view of acoustic velocity, density and stiffness such that they do not deviate from each other by more than 10% without having piezoelectric effect. The functional layer my be of the same crystalline constitution as the useful piezoelectric layer but without piezoelectric properties.

Abstract: The invention relates to a deformable body with a hole which is suitable for receiving an anti-creepage ring and a fastener, wherein the hole has a central axis and the hole is delimited by the deformable material which forms the deformable body, wherein the body comprises a deformable protruding ring which surrounds the hole and protrudes in the direction of the central axis and a projection which surrounds the hole and is arranged at a distance from the protruding the ring in a direction perpendicular to the central axis, and the ring protrudes beyond the projection in the direction of the central axis.

Abstract: A plug-in nut has an outer body and an inner body which is mounted in the outer body such that it can be displaced in a rotationally fixed manner. On the inner body, rear-latching lugs are formed on spring arms, which rear-latching lugs fix an attachment component on a carrier part in a variable position of the inner body in relation to the outer body, which variable position is assumed so as to compensate for tolerances, as soon as a screw has been screwed into a screw receiving space of the inner body. This results in a secure hold with very simple handling.

Abstract: An expanding rivet formed with a rivet body and with a rivet pin includes foot webs formed on the rivet pin, which foot webs project laterally in a pre-fitting position relative to spring arms formed on the rivet body. As a result, the free ends of the spring arms are protected against damage when the expanding rivet is inserted into a locating recess.

Abstract: A fastening device having equalization elements, which are movable in the longitudinal direction of a receiving sleeve for adjustment to different diameters of oblong fastening elements such as coarse thread bolts, which hold the fastening element substantially without play in the receiving sleeve in dependence on the diameter of the respective fastening element.

Abstract: A fastening arrangement includes a locking part having a head plate and a foot shaft configured with catch noses, bearing tenons, and spring webs having catch noses and web wings. The receiving element includes a profiled surface and an edge wall including inwardly convex portions and outwardly concave portions. When the locking part is in a mounted position, the bearing tenons are disposed in first depressions while the spring webs are in a rear engagement position in which the catch noses engage behind an element. When the locking part is in a demounted position, the bearing tenons are disposed in second depressions and the spring webs are in a released position in which they are out of engagement with the element.

Abstract: The invention relates to a fixing device comprising a closing part (8) which comprises a head plate (9) and a base shaft (11) equipped with clips (24). Spring webs are arranged on the base shaft (11) whereon a clip (24) is arranged, webbed wings are formed and journals are embodied. The receiving element (12) also comprises an edge wall (14) which is fitted with projecting sections and recesses, in addition to a profile surface. When the closing part is in the mounted state, the journals are arranged in a first recess and the spring webs are in a rear engaging position, wherein the clips engage behind the component (3). When the closing part (8) is in the demounted state, the journals are arranged in a second recess and the spring webs in a released position, wherein the journals are arranged in an engaging-free manner in relation to the rear engaging position. As a result, the components (1, 2, 3) are clipped together and can be detached from each other in a very simple manner.

Abstract: A device for fastening an accessory to a support has a plug-in part (1) with a plug-in shaft (3) to be inserted into a recess in the support, and a head shaft (7) that has a head plate (8) and a counterplate (10) between which an engagement system (9) is developed. A guide strap (11) that has a guide recess (12) is formed on the counterplate (10), which is located on the side facing the head shaft (7). There is also a slider (2) that is mounted to be movable in the guide recess (12) toward the engagement system (9) and is made with a locking system (16) that is engaged with the engagement system (9) when the slider (2) is advanced into a locking position. This allows an accessory with a section located between the slider (2) and the counterplate (10) to be connected to the support.

Abstract: A device for fastening an attachment (4) to a support part (18) is provided with a bearing part (1) that can be connected to the attachment (4) via connecting means (2); with a rivet pin (8) seated in a rivet aperture (7) of the bearing part (1) displaceably between a preassembly position and a final assembly position and comprising laterally projecting latching projections (15) and a pin receiving shaft (12), said latching projections (15) being operative in the final assembly position to engage behind the support part (18); and with a lock pin (13) seated in the pin receiving shaft (12) displaceably between a released position and a locked position, said lock pin (13) being operative in the locked position to block radial movement of the latching projections (15).

Abstract: The invention relates to a line clip, by means of which adjacent supply lines of varying types or other long components can be fixed together or fixed to a support piece. The above comprises a housing piece (1), with retaining recesses (5) embodied therein to match the cross-sections of the lines concerned, clipping arms (6), moulded on both sides of the retaining recess (5), which are inclined towards each other and a securing clip (2) which way be placed over the housing piece (1) with counter recesses (16) embodied thereon which are complementary to the reraining recess of the housing piece (1) and also match the cross sections of the lines. Locking elements (18) are moulded at both ends of the housing piece (1) and the securing clip (2), which clip into each other on placing the securing clip (2) on the housing piece (1).

Abstract: Sleeve for pre-assembly of a flat gasket on a sealing surface of a machine component having a hole for insertion of the sleeve therein, the flat gasket having a hole for passage of the sleeve therethrough, and the one, first end area of the sleeve being elastically compressible in order to reduce its outer diameter; in order to make pre-assembly of a flat gasket on a machine component as simple as possible, the sleeve has stops on the outer circumference of its first end area, which act in both directions of the sleeve axis to hold the sleeve on the gasket plate in an axial position predetermined by the stops, and the sleeve is also of such configuration at its outer circumference that insertion of the sleeve in the hole of the machine component results in a frictionally engaged and/or positively locked connection between the machine component and the sleeve.
