  • Patent number: 6149762
    Abstract: A nozzle includes a body, a substantially rectangular foot, air slots and a flow restrictor. The body directs a stream of hot air into the substantially rectangular foot. The foot has a top and bottom surface that includes air slots. The foot also has an outlet across one end for the air flow. A flow restrictor is positioned in the foot, substantially along the outlet to create a back flow of pressure within the foot. The back flow of air causes an even distribution of air across the foot and out the air slots. Thus, increasing radiant heat across the surfaces of the foot.

  • Patent number: 6149415
    Abstract: An improved internal gear pump design is provided whereby the head plate includes a groove located vertically above the crescent for providing improved axial feed to the roots or innermost spaces between the idler teeth. The design of the pump also includes a stepped shaft design whereby the radius of the shaft immediately adjacent to the rotor is greater than an adjacent outboard section of the shaft. As a result, a chamber for housing the seal assembly is defined as the space between the stepped shaft portion, the annular seal plate, the outboard section of the shaft that has a lesser or reduced diameter, and the casing. The casing may also include a recess for providing sufficient space for the seal assembly. The larger section of the shaft is accommodated in a bushing mounted to the inside surface of the casing. The inside diameter of the bushing is large enough to accommodate the larger stepped portion of the shaft as well as the outside diameter of the seal assembly.

  • Patent number: 6150675
    Abstract: A semiconductor component having a control structure for modulating the conductivity of a channel region wherein a small-area gate electrode of the proposed component covers the substrate only over a length L.sub.gd .apprxeq.L.sub.dep (L.sub.dep :=width of the space-charge zone in the substrate). An auxiliary electrode conductively connected to the source metallization and extending up to the edge of the symmetry unit is embedded in the gate oxide and is arranged spaced from the gate electrode. It sees to a comparatively uniform field distribution in the edge region of the gate electrode and thus prevents the electrical field strength in the semiconductor from reaching the critical value of approximately 10.sup.5 V/cm that triggers surge ionization.

  • Patent number: 6147562
    Abstract: A master and slave arrangement of processors includes a clock signal synchronization apparatus. The clock signals of two (processor) assemblies in micro-synchronous operation are only allowed to exhibit an extremely slight phase difference. A system clock signal is generated by a voltage controlled oscillator, which is fed by phase detectors with a filter at the output of each phase detector. Switches are provided between the filter output and the voltage controlled oscillator input. The phase detectors compare the system clock signal and a reference clock signal. A delay is provided at the input of one phase detector.

  • Patent number: 6145626
    Abstract: A system for the delivery and control of an air/oil mixture used to lubricate large bearings in heavy duty applications such as steel mills is provided. The system includes a mixing module for mixing air and oil and delivering the air/oil mixture through a plurality of connecting lines to a plurality of bearing housings. Each of the connecting lines or the outlet leading to the connecting line is, in turn, connected to its own individual solenoid. Each solenoid is connected to a common pressure transducer which is connected to a controller. The controller sequentially opens the solenoids one at a time thereby establishing communication between one of the connecting lines and the common transducer at a time. The transducer receives pressure signals fr6m each connecting line converts the pressure signals to analog signals before transmitting the analog signals to the controller.

  • Patent number: 6147383
    Abstract: An LDD-structured field-effect semiconductor device that can eliminate fluctuations in the threshold voltage caused by variations in the position of higher-density diffusion layers, thereby suppressing variations in the threshold voltage to a lower level. The junction depth of each of the lower-density diffusion layers in contact with a substrate is greater than the depth of a depletion layer at the place corresponding to a portion of the channel region contacting the source region. This prevents a change in the positional relationship between diffusion layers serving as, what are referred to as "pocket layers", and the depletion layer adjacent to the source, even though the position of the higher-density diffusion layers is varied in the longitudinal direction of the channel due to variations in the width of a spacer.

  • Patent number: 6148292
    Abstract: In a method for statistics mode reloading and for the statistical acquisition in the storage of a dataset in an electronic postage meter machine, the statistics mode of the electronic postage meter machine created for the acquisition of pre-compressed data according to statistics classes (postal classes) is interchangeably installed. A formation of freely selectable, new statistics instruction data for a future statistics mode ensues in the data center for the purpose of a transmission in the form of an instruction dataset. The installation of the statistics mode ensues during a communication of the postage meter machine with the data center. A microprocessor of the postage meter machine is programmed to change the statistics mode by modem or with another suitable communication means at least periodically or when the mail carrier is changed, or within the framework of a reloading of the postage meter machine.

  • Patent number: 6145353
    Abstract: A door lock assembly which includes an electronic card reader is provided whereby when the clutch assembly is in the activated position, rotational movement of the outside handle is transmitted by way of a spindle through the mortise and through the clutch assembly to a clutch disk disposed between the mortise and clutch assemblies and the inside housing. The clutch disk is disposed inside the door. Rotational movement of the clutch disk is then imparted back towards the door through a drive disk and hub drive to the mortise latch hub which is disposed in the mortise housing disposed inside the door structure. As a result, the clutch disk and clutch assembly can be disposed between the inside housing and the inside door surface and the electronic components of the card reader and clutch assembly can be conveniently housed in the inside housing assembly.

  • Patent number: 6146165
    Abstract: The eject mechanism is composed of a two-arm lever actuatable with a ram, so that an actuation of the ram acting on the first lever arm creates a release of the plug in contact and an eject motion of the plug in assembly with the assistance of the second lever spatially allocated to the plug-side end of the plug in assembly. In order to achieve different transmission ratios, the first lever arm and the end of the ram facing toward it are fashioned and spatially allocated to one another so that the ram applies to a long lever arm in a first lever phase and applies to a short lever arm in a second lever phase.
