    Abstract: In one embodiment, a semiconductor die includes a polycrystalline semiconductor resistor structure (poly resistor structure). The poly resistor structure includes a resistive path between a first terminal and a second terminal. The poly resistor structure includes a first region having a net first conductivity type dopant concentration located in the resistance path and a second region having a net second conductivity type dopant concentration located in the resistance path. A silicide structure is located on both a first portion of the first region and a first portion of the second region to electrically connect the first portion of the first region and the first portion of the second region. In some embodiments, poly resistor structures with different conductivity type regions can be connected together.

  • Patent number: 10475783
    Abstract: Various embodiments are directed to electrostatic discharge (ESD) protection apparatus comprising a bipolar junction transistor (BJT) having terminals, a field-effect transistor (FET) having terminals, and a common base region connected to a recombination region. The BJT and the FET are integrated with one another and include a common region that is shared by the BJT and the FET. The BJT and FET collectively bias the common base region and prevent triggering of the BJT by causing a potential of the common base region to follow a potential of one of the terminals of the BJT in response to an excessive but tolerable non-ESD voltage change at one or more of the terminals.

  • Patent number: 5799224
    Abstract: A photographic sheet material processing apparatus has a plurality of treatment cells (12', 12", 12'") mounted one above another in a vertical stack to define a substantially vertical sheet material path (20) through the apparatus. The apparatus is cleaned by feeding a cleaning liquid to a first cell (12'), allowing at least a portion of said cleaning liquid to pass by gravity from said first cell (12') to at least one further cell (12"), and discharging said cleaning liquid from the apparatus. This process provides a convenient and efficient method of cleaning a vertical photographic sheet material processing apparatus.

  • Patent number: 5745816
    Abstract: A roller, for use in a photographic sheet material processing apparatus, comprises a core (32) provided with a covering of relatively soft material (34). The roller has a length (L) of from 0.4 to 2.0 m. The core has a maximum diameter (D) of less than 0.04*L m. The roller is characterised by having a deflection as measured by a specific test and a weight (W) below levels defined by a specified boundary condition formulae (1) & (2). Rollers satisfying this condition are characterised in that the core is formed of a composite material comprising fibers and a resin matrix. Such rollers have a relatively small diameter, are light and yet still have sufficient stiffness to avoid substantial wrinkling of the sheet material in the apparatus and to satisfy the requirements of high processing quality.

  • Patent number: 5663898
    Abstract: A method is disclosed for diagnosing the cause of bad performance of a printing plate obtained using the silver salt diffusion transfer process. According to the method a problem table is used to relate a problem to one or more possible causes. A test table is used to identify tests to verify a possible cause of the problem and a toolkit is provided including equipment needed for carrying out tests. Using the method a technician can identify possible causes for a problem, identify the tests capable of verifying one or more causes and perform the tests to confirm the cause of the problem. In the event a cause is not confirmed the technician can investigate other possible causes.

  • Patent number: 5606720
    Abstract: Apparatus for processing a photographic sheet material in at least one processing stage which includes a feed roller array for transporting the material to or from the stage. The feed roller array has a pair of rollers supported on shafts for rotation and mounted with one superposed generally above the other. The upper roller is driven in a transport direction by a drive mechanism acting on an end of its shaft. The opposite ends of the shafts of the two rollers are journaled in frame members with the lower roller being supported for limited independent movement toward and away from the upper roller. The lower roller is normally biased into contact with the upper roller and is adapted to be displaced vertically away from the upper roller by a cam arrangement acting on the ends of its shaft. The upper roller is adapted to be shifted axially to disengage an end of its shaft from its journal to permit the upper roller to be removed manually from the apparatus.
