Appl. No.:

10/373936

Inventors:

Clifton Quan - Arcadia CA
Jar J. Lee - Irvine CA
Brian M. Pierce - Moreno Valley CA
Robert C. Allison - Rancho Palos Verdes CA

Assignee:

Raytheon Company - Waltham MA

International Classification:

H01Q 300

US Classification:

343754, 342376

Abstract:

A microelectromechanical system (MEMS) steerable electronically scanned lens array (ESA) antenna and method of frequency scanning are disclosed. The MEMS ESA antenna includes a wide band feedthrough lens and a continuous transverse stub (CTS) feed array. The wide band feedthrough lens includes first and second arrays of wide band radiating elements and an array of MEMS phase shifter modules disposed between the first and second arrays of radiating elements. The continuous transverse stub (CTS) feed array is disposed adjacent the first array of radiating elements for providing a planar wave front in the near field. The MEMS phase shifter modules steer a beam radiated from the CTS feed array in two dimensions.

International Classification:

G03C 500
H01L 2100
G01R 3126

US Classification:

430 30

Abstract:

A method of and apparatus for processing semiconductor wafers which include observing optical characteristics of exposed undeveloped photoresist, without removing the wafers from the stepper is disclosed. The present invention includes the steps of loading a wafer having a layer of photoresist into a photolithography system, exposing the photoresist in accordance with an initial set of control parameters including exposure time, position of the wafer within the photolithography system, and/or focus change. Prior to developing the photoresist, optical characteristics of the exposed photoresist are observed using a phase contrast microscope which detects latent images. Then, according to the observations of the latent image, the initial set of control parameters are adjusted to generate a second set of control parameters.

Assignee:

Smith International, Inc. - Irvine CA

International Classification:

E21B 908

US Classification:

175364

Abstract:

This earth boring drill apparatus has a cutter mounting leg extending from one side of a drive stem and a removable cutter assembly, including a fixed shaft and cutter journaled for rotation on the shaft supported between the drive stem and the mounting leg. The stem has a bore for slidably receiving the inner end of the shaft. The cutter mounting leg terminates in an end surface extending parallel to the axis of rotation of the bore and shaft. A shaft supporting lug projecting from the outer end of the shaft has a surface which is parallel to the end surface on the leg. The opposed surfaces respectively have a V-shaped projection and mating groove which provide lateral alignment and prevent shaft rotation while permitting the shaft to be movable in an axial direction by an amount sufficient to permit the shaft to be withdrawn from the bore. Bolts extending between the mounting leg and the shaft at an angle clamp the mating surfaces of the groove and projection together and also clamp a pair of flat spacers between the mounting leg and the outer end of the shaft to lock the shaft in the bore.

Assignee:

Smith International, Inc. - Irvine CA

International Classification:

E21B 908

US Classification:

175340

Abstract:

A raise type of earth boring drill in which the cutter assembly is detachably secured to the drive stem to permit replacement of the stem. The stem slidably engages a central opening in the cutter assembly, the cutter assembly engaging a shoulder on the stem which carries axial loads in the drill. The cutter assembly is detachably anchored by a plurality of bolts to a torque plate attached to the end of the stem for transmitting torque load to the cutter assembly, the bolts clamping the cutter assembly against the shoulder.
