Patent number: 5900663Abstract: A quasi-mesh gate structure for the RF MOS transistor having a conductive plug source-body-backside connection is disclosed. The RF MOS transistor having the quasi-mesh gate structure utilizes significantly shorter feeding gate paths as compared to the long feeding gate paths used in the prior art RF MOS devices. The RF MOS transistor having the quasi-mesh gate structure can utilize the polysilicon gates or silicided gates. This results in simplification of the fabrication process and/or improved performance at high frequencies.Type: GrantFiled: February 7, 1998Date of Patent: May 4, 1999Assignee: XEMOD, Inc.Inventors: Joseph Herbert Johnson, Pablo Eugenio D'Anna

Patent number: 5256923Abstract: A switched reluctance motor (10) provides position and speed detection without a shaft position sensor. At least one of the stator pole faces (54) and/or at least one of the rotor pole faces (60) has an irregularity such as a notch (52 and/or 58) providing a perturbation or blip (70, 82) in the inductance profile (72, 76, 84) of the motor (10) during rotation of the rotor (14) indicative of the position of the rotor (14) relative to the stator (12). The frequency of the perturbations indicates motor speed.Type: GrantFiled: May 11, 1992Date of Patent: October 26, 1993Assignee: A. O. Smith CorporationInventors: Ronald P. Bartos, Timothy H. Houle, J. Herbert Johnson

Patent number: 4479446Abstract: A sewing machine system possesses an interactive communication capability allowing for the assignment of stitch patterns with respect to workpieces to be sewn. The workpieces are arranged within pallets having binary codes impressed thereon. The stitch pattern assignments are made in conjunction with the sensing of the binary codes. The workpieces are automatically processed from a location wherein the binary codes are sensed, to a location wherein the pallets are attached to an automatic positioning system. The workpieces are furthermore processed through to an output position when the respectively assigned stitch pattern has been sewn.Type: GrantFiled: May 22, 1981Date of Patent: October 30, 1984Assignee: USM CorporationInventors: Herbert Johnson, Richard M.

Patent number: 4422393Abstract: A system for processing workpieces prearranged within pallets that are to be sewn by a sewing machine. The system includes apparatus for automatically processing a pallet from an input location to a location wherein the pallet can be automatically attached to a positioning system. The positioning system moves the attached pallet into position underneath the sewing machine head for subsequent sewing of a stitch pattern. The sewn workpiece is returned to a location where the pallet can be detached from the positioning system. An ejector mechanism automatically moves the detached pallet to a location which does not interfere with the automatic processing of another pallet loaded at the input location.Type: GrantFiled: May 22, 1981Date of Patent: December 27, 1983Assignee: USM CorporationInventors: Herbert Johnson, Richard M. Elliott, Donald F. Herdeg, Alan M. Peck

Patent number: 4177098Abstract: An improved machine and method for stiffening a selected portion of a sheet-like member generally flattens that portion, next deposits on a chill plate matrix an adhesive hot melt deposit of mostly uniform thickness except for a margin of added thickness for slower hardening, and then causes the matrix with impact to press all of the adhesive, while the added thickness margin is still softer than the uniform adhesive thickness, against the flattened portion of the member, thus transferring the adhesive to that portion, the added thickness margin being exuded laterally and hence taperingly reduced to provide diminishing stiffness toward an edge merging with the member.The machine and method have particular advantage in stiffening a toe portion of a shoe upper, rendering the instep margin of the vamp or a toe piece free of irregularity, and assuring ultimate comfort for wearing in an assembled shoe.Type: GrantFiled: July 8, 1977Date of Patent: December 4, 1979Assignee: USM CorporationInventors: Robert F.
