Patent EP-0286178-A2 (EP)
Inventor: VERMEER ADRIANUS JOHANNES PETR
IPC: B25J15/08
Filed: 1988-04-05
Abstract: A gripping device for an apparatus for placing electronic and/or electrical components, in particular DIL components, on a substrate comprises a pair of grippers (1 and 2) which are movable towar s and away from one another to close and open the jaws (4 and 5) of the grippers. To enable the device to handle components of different widths without the risk of damaging the terminal pins of the components, a stop member in the form of a vertically disposed stepped pin 12 is provided between the grippers for abutment by horizontally extending rib-like projections (8 and 9) on the inner sides of the gripper jaws to limit movement of the grippers in the closing direction. The portions of the pin that are separated by the step (or steps) have different diameters corresponding to the different widths of component that the device is required to handle, and the pin is coaxially adjustable by fluid-pressure operated means in the form of a piston (15) to bring the portions of the pin selectively into an operative position between the projections on the gripper jaws for engagement by these projections to determine a closed position of the jaws for a particular width of component.

Abstract: An ultrasonic probe 10 includes an elongated housing 12 which contains a window 24 surrounding a ultrasonic transducer 32. The ultrasonic transducer 32 is mounted on a first platform 36. The first platform 36 is in turn mounted on a second platform 38. A motor 44 and linkage arrangement 48 is provided for pivoting the transducer 32. A thumb wheel 16 can rotatably position the transducer 32 as it pivots, allowing ultrasonic imaging of bodily tissue through three hundred and sixty degrees. Further, a position sensor 78 allows for accurate sensing of the position of the transducer 32 as the transducer 32 pivots and rotates. 
     An external fluid jacket 64 for a wobbler type ultrasound probe 10 includes a cylindrical body 62 with an opening 64 which allows an ultrasound signal to be sent from and received by an ultrasound transducer 26 through a window 24 provided in the probe 10. The fluid jacket 60 includes a recessed portion72 which provides for the transmittal of fluid from an internal port 22 defined by the probe 10 to an edge 65 of the opening 64 so that the fluid can be provided immediately adjacent the window 24 of the probe 10. This enables the fluid to fill the space between the probe 10 and the sheath 42 and also to evacuate this fluid in order to properly position a probe 10 in a bodily cavity and to remove the probe 10 once imaging has been completed.

Abstract: In a navigation system, a first external storage device (16) which may be a CD stores data representing a standard map of a particular area and that required for guidance, and a second external storage device (17) which may be an IC card stores individual data which cannot be complemented by said data representing the standard map and said guidance data. Since the data is stored in both CD and IC card, the number of data can be reduced. This makes the operation simpler and enables data that meets the demand of a user to be selectively supplied to the user. In consequence, guided navigation is made possible from any starting point to a destination, and data updating can be made relatively easy.

Abstract: A clamping device (20) for a rigid record disk file includes an annular member (22) that acts through a spacer ring (21) to clamp a stack of rigid disks (10) in spaced parallel relationship to a hub (13) having a portion (12) supporting the lower end of the stack. The annular member has a plurality of uniformly spaced radial slots (23) to define a plurality of substantially identical tapered leaf springs (24). Each leaf spring terminates at its wider end in a common solid hoop-shaped rim (25) that overhangs and contacts the spacer ring (21) along a circular line in the same horizontal plane as, and near, the centroid of the cross-sectional area of the rim when the clamp is uncompressed. Upon application of a compressive force in an axial direction concurrently to the small innermost ends of all said leaf springs, the rim pivots at and along the aforementioned circular line to substantially eliminate radial load transmitted via the spacer ring to the top disk when clamping the stack to the hub. A minimal spring constant results from substantially uniform stress distribution across and along each tapered leaf spring.

Abstract: A paste-like composition containing a lead salt of an organic acid and tin powder is applied on a pad array portion of a circuit board. Then, the paste-like composition is heated so as to cause precipitation, thereby forming a solder layer formed of an Sn-Pb alloy substantially only on pads. This precipitation is performed in a state that a liquid pool is formed on the pad array portion when the paste-like composition is liquefied by heating, and the tin powder is settled in the liquid pool. When an electronic part is to be mounted on the pads, first, preparatory solder layers are formed on the pads by the above-mentioned precipitation process. After a paste-like composition is applied on the preparatory solder layers, the electronic part is put on the paste-like composition. Then, the paste-like composition is heated, thereby soldering leads of the electronic part with the pads.

Blocking means are provided for blocking the receiving simulator from advancing its simulated time clock ahead of the next state change time of the transmitting simulator.
