Patent number: 6465935Abstract: An ultrasonic transducer having a pot-like casing has an outer bottom face which is designed in part as a vibrating diaphragm. A stabilizing ring is arranged on the outside of the wall of the pot-like casing, imparting a greater rigidity to the casing and limiting the ultrasonic vibration essentially to the bottom of the pot as a vibrating diaphragm. The propagation and reception beams of the ultrasonic waves can be shaped further by an additional arrangement of a sound directing device in the area of the vibrating diaphragm.Type: GrantFiled: December 29, 1999Date of Patent: October 15, 2002Assignee: Robert Bosch GmbHInventors: Dietmar Wannke, Dieter Karr, Meike Fehse, Martin Noll, Peter Rapps, Waldemar Ernst, Dirk Schmid

Patent number: 6318774Abstract: An arrangement having a module for installation in a bumper of a motor vehicle and having a retaining part for attaching the module to the bumper. The retaining part, in this context, is fixedly attached on the interior side of the bumper blade, so that the module can be inserted from the interior side. Provision is made in the bumper for a corresponding bore, through which the head piece of the module can be plugged in until the surface is roughly flush with the exterior surface of the bumper. As the module, an ultrasonic sensor is preferably proposed, which can be used for measuring distance in a motor vehicle. Since only the head piece of the module is visible from the outside but not its attachment parts, the resulting appearance is particularly advantageous since it is not disruptive from a design point of view.Type: GrantFiled: February 18, 2000Date of Patent: November 20, 2001Assignee: Robert Bosch GmbHInventors: Dieter Karr, Meike Fehse, Martin Noll, Peter Rapps, Waldemar Ernst

Patent number: 6308767Abstract: In a casting furnace employing a liquid metal bath to allow directional solidification of an article from a melt, and a method of operating such a furnace, a system is provided for lowering the mold from within a heating chamber into a liquid metal bath situated immediately beneath the heating chamber. An automated system is provided for automatically maintaining the level of the liquid metal bath at a relatively constant position immediately beneath the heating chamber, wherein simultaneously upon the level of the bath having risen due to immersion of the mold within the bath, the bath is lowered to thereby permit the level of the liquid metal bath to be maintained in a substantially fixed position.Type: GrantFiled: December 21, 1999Date of Patent: October 30, 2001Assignees: General Electric Company, ALD Vacuum TechnologiesInventors: Franz Waldemar Ernst Hugo, Ulrich Betz, Helmut Mayer

Patent number: 6185100Abstract: In a control device the printed circuit board (10) rests on a rim (28) of the housing bottom (26). The power components (14) to be cooled are arranged in the area where the printed circuit board (10) rests on the rim (28). In order to achieve an even contact pressure of the printed circuit board (10) over the entire support surface, a contact pressure on the power component (14) or on the printed circuit board (10) is generated with the help of additional aids. It is possible here to use spring elements (30) or elastomer strips (31) acting on the power component (14). Furthermore, multi-part support elements (40), or respectively plastic elements (45) can also be employed, which respectively act directly on the printed circuit board (10). A good heat dissipation from the power component (14) via the rim (28) of the housing bottom is possible by means of this.Type: GrantFiled: January 25, 1999Date of Patent: February 6, 2001Assignee: Robert Bosch GmbHInventors: Willy Bentz, Peter Jares, Dieter Karr, Paul Hermanutz, Waldemar Ernst

Patent number: 5922991Abstract: In order to improve an arrangement for mounting a wiring harness on a support plate with a laminated-on substrate for electrical and/or electronic components such that the latter has high reliability while being simpler and thus more economical to manufacture, the connecting wires of the wiring harness are connected in electrically conductive fashion directly to electrical connection elements of the substrate. In the vicinity of this connection, the wiring harness is at least partly embedded into a sealing medium enclosing the connection.Type: GrantFiled: March 28, 1997Date of Patent: July 13, 1999Assignee: Robert Bosch GmbHInventors: Willy Bentz, Paul Hermanutz, Waldemar Ernst
