摘要： This invention relates to overload protection for a circuit driving a direct current (DC) load. The invention provides a method of generating an overload condition for an output module driving a load having a load current and a load voltage comprising the steps of: monitoring the load current at sample intervals; comparing the monitored load current to a predetermined load current threshold; starting an overload timer in the event that the timer is not running and the monitored load current is greater than said load current threshold; monitoring the load voltage at said sample intervals; generating a ramped load voltage waveform for reference purposes in dependence upon an initial load voltage and a predetermined step size load voltage in the event that the overload timer is running; generating an overload condition in the event that the monitored load voltage is less than said ramped load voltage reference waveform, the ramped load voltage is less than a predetermined positive ramp limit and the overload timer is running.

摘要： A reproducing machine in which a member has successive latent images recorded thereon. The reproducing machine includes a pair of developer units. One developer unit is located in the operative position in the reproducing machine with the other unit being remote therefrom. Each developer unit contains different colored particles. Color changes are achieved by interchanging developer units to develop one latent image with particles of one color and the other latent image with particles of the other color.

摘要： Improved stripping of a transfer member (having a developed image thereon) from a photoconductive surface of an electrostatic reproduction machine is effected by charging the lead edge of the member with a first charge, and then charging the body of the member having the developed image thereon with a second charge which is different than the first charge. The second charge has a magnitude and polarity which prevents retransfer of the developed image to the photoconductive surface.

摘要： A process for fabricating an electronic module (30) and a packaged electronic device (56) having a thermally conductive substrate includes the step of thermally spraying of a dielectric layer (12) onto a baseplate (10). An electrically conductive layer (18) is then direct bonded to the thermally sprayed dielectric layer. The thermally sprayed dielectric layer can be formed at selected locations on the upper surface of the baseplate (10) by forming a pattern on the upper surface prior to carrying out the thermal spraying process. The electrically conductive layer (18) is patterned to form an interconnect pattern overlying the baseplate. Because the thermal spraying process can form extremely thin dielectric layers, an electronic module (30) fabricated in accordance with the invention exhibits high heat transfer characteristics. A heat producing electronic component (24), such as a power transistor, can be attached to the electrically conductive layer (18), and the heat generated therefrom dissipated through the baseplate (10).
