Abstract: An optical section (3) and a lens holder (4) are fixed to each other in a state where the lens holder (4) is at an intermediate position within a movable range so that the optical section (3) does not come into contact with an image pickup section (10) in a case where the lens holder (4) is driven within the movable range. This makes it possible to provide (i) a camera module in which it is possible to reduce the influence of a tilt that occurs in the vicinity of an infinite-distance side mechanical end and also reduce the influence of a tilt that occurs at an intermediate position away from the infinite-distance side mechanical end and a macro side and in which image pickup lenses are attachable with high positional accuracy and (ii) a method for producing a camera module.

Abstract: A pipe processing tool that is configured to deform the end of a pipe so that the circumferential shape of the end of the pipe generally matches the circumferential shape of an adjacent pipe end. Matching the circumferential shapes of the pipe ends is advantageous during a pipe attachment process. The pipe processing tool can include a deformation ring with a plurality of pipe deformation members. Each pipe deformation member faces radially inward and is actuatable in a radial direction toward and away from the center of the deformation ring in order to permit engagement with the pipe. Each pipe deformation member is individually and separately actuatable from the other pipe deformation members so that the circumferential shapes of the pipes can be altered by controlling suitable ones of the pipe deformation members.

Abstract: A quick connect liner latch system assembly (QCLL). The QCLL latches each joint of a slick line deployed liner together quickly and easily. This system can set an anchor in an existing well bore at a shallow depth and run a new liner in the well with a slick line unit using the QCLL system. It is a safer operation for the workers and environment and cost savings to the operator. The QCLL has two main sections that are locked together to form the full QCLL. The upper and lowers sections are locked together using a body lock ring. The units are not threaded together, which eliminates the need for a conventional rig for installation. The QCLL is unique because the inside diameter (ID) of the latch can remain large enough to accommodate a standard liner wiper plug for the weight of the liner being run into the well.
