  • Patent number: 5431771
    Abstract: A method for embodying a display cell with a counter-electrode contact pickup. Contact blocks 12 are separated from counter-electrode contacts 20 by passivation film 22. The electrodes linked between the counter-electrode and the contacts 20 are obtained by calcining the glue of the blocks so as to render them conductive by using a laser beam 30. In addition, the passivation film 22 is perforated by using the laser beam 30. This method finds particular application in the embodiment of liquid crystal display screens.

  • Patent number: 5432464
    Abstract: A type of electronic circuit, called an Application Specific Integrated Circuit (ASIC), is used to customize the functions in a semiconductor chip as defined by a user. ASIC includes a microprocessor, functional inputs and outputs, connection circuits, electronic gates, inhibition gates and links to perform "application specific" operations. The user chooses the functions and the arrangement of the various connection circuits from a menu of predetermined functions. Once the ASIC has been defined by the user, it is ready for manufacturing.

  • Patent number: 5297720
    Abstract: A method of assembling a mechanical part on a support includes making a projecting thickening situated substantially over a connection face of an anchor block of the part; depositing a layer of one of the components of a eutectic on at least one fixing zone of the support; using a tool for holding the thickening to move the part so that its connection face co-operates with the fixing zone of the support; raising the temperature of the eutectic point of the eutectic; exerting localized force on the thickening; and simultaneously subjecting the part or the support to mechanical stresses. The invention is particularly applicable to assembling a capacitive sensor. The invention is also directed to a mechanical part for carrying out the assembly method, as well as a tool for grasping the mechanical part.
