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.

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.

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.

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.
