  • Patent number: 12365098
    Abstract: A gripper for a handling assembly grasps an object. The gripper includes: a coupler for mounting to the object; and a base body mountable to the handling assembly. The base body includes: a housing; a clamping bracket at an outside of the housing; and a clamping mechanism in the housing, connected to the clamping bracket. The clamping bracket has latched and unlatched states. In the latched state, the clamping bracket is drawn close to the housing. In the unlatched state, the clamping bracket is pushed away from the housing to receive the coupler between the clamping bracket and the housing. The clamping mechanism is activated by pneumatic/hydraulic driving to force the clamping bracket to change from the latched to the unlatched state, and deactivated such that the clamping bracket returns to the latched state, thereby clamping the coupler to the housing.

  • Patent number: 7071680
    Abstract: A position transducer device is provided for detecting the position of a position transmitter. The position transducer device comprises a housing extending in a longitudinal direction and a measuring sensor arranged in the housing and extending parallel to the longitudinal direction. The position transmitter is coupled to the measuring sensor in a non-contacting manner. The outer surface of the housing is designed such that it can be enclosed at least partially by a fixing receiving means for fixing the housing to an application. The housing can be rotated relative to the position transmitter in the fixing receiving means in order to enable adjustment of the distance between the measuring sensor and the position transducer.

  • Patent number: 6591703
    Abstract: A sensor has a housing, in which there is arranged a thermosetting molding compound which is encapsulated in a linear region in the longitudinal direction of the housing by a thermoplastic molding compound. The two molding compounds meet at a conical contact surface. An electrical terminal element is electrically connected to a printed-circuit board via lines. The printed-circuit board is embedded into the two molding compounds at the level of the center line, the thermosetting molding compound enclosing all the electrically active components and conductor tracks of the printed-circuit board. Annular grooves are arranged on the outer side of the thermosetting molding compound. Due to the encapsulation, the thermoplastic molding compound engages in these annular grooves in a positively and non-positively engaging manner.

  • Patent number: 6153916
    Abstract: An MOS transistor with high output voltage endurance comprises a semiconductor substrate with the surface thereof including a doping area having a surface doping concentration decreasing from the drain connection area to the drain-side edge of the gate oxide layer. This doping area is formed by ion implantation and subsequent outdiffusion of individual partial areas. The first partial area has a size in the drain-gate extension which is considerably larger than the penetration depth of the outdiffusion in the substrate. The second partial area has a size and a distance to the first partial area which are both smaller than the penetration depth of the outdiffusion in the substrate. In the outdiffused condition, the individual diffusions originating from the individual, respectively adjacent first and second partial areas merge into each other on the surface of the substrate to thus obtain a doping concentration gradient for a constant conduction type of the doping area.

  • Patent number: 5550069
    Abstract: A method for producing a PMOS transistor. A p doped substrate and an n doped trough are provided by implantation and subsequent diffusion. The transistor is insulated by means of a field oxide layer. The transistor gates are produced using a photolithographic pattern. The photoresist left from the photolithographic pattern after the gate is etched is used as the mask of the drain region at the gate-side end for at least one p.sup.- implantation. The thickness of the edge of the photoresist layer decreases towards the surface of the drain region at the gate edge. Due to this decreasing thickness, when the implant is introduced the flank (17, 19) of the implantation concentration profile (16, 18) is deflected towards the channel below the gate region.

  • Patent number: 4256356
    Abstract: In equipment in which a number of plug-in subassemblies, such as printed circuit boards, for example, are arranged, the printed circuit boards are usually inserted in resilient strips of plug-in connectors for the purpose of establishing electrical contact for the conduction strips arranged on the printed circuit boards. These resilient strips are fixed to the rear portion of the supporting frame of the equipment. Appreciable force and satisfactory guidance are required for inserting and withdrawing the plug-in subassemblies. For the purpose of inserting or withdrawing the plug-in subassembly a lever is arranged in a rotary bearing on the plug-in subassembly. Toothed wheel segments are provided at the end of the shorter lever arm of this lever and engage in toothed rack sections of a profile strip which is substantially horizontally positioned. When the lever is actuated, the toothed wheel segments roll in the rack sections.
