  • Hot air generator burner with interchangeable lighter
    Patent number: 9482430
    Abstract: A heat-shrink gun in which an ignition voltage of the gaseous mixture is generated by a piezoelectric lighter (12), under the action of a trigger (8) when it is moved from a waiting position (8A) to a lighting position, characterized in that the trigger can also assume a loading position (8B), in which it free access (DC) to a working housing for the lighter.

  • Method of fabricating a thin-film transistor
    Patent number: 5061648
    Abstract: A thin-film transistor comprises a source electrode and a drain electrode formed in a spaced-apart relation to each other on a substrate, a semiconductor layer formed over the source and drain electrodes, a gate insulating film formed on the semiconductor layer and a gate electrode on the gate insulating film. First and second ohmic contact layers are formed in the entirety of the surface regions of the semiconductor layer which are in contact with the source and drain electrodes.
