A novel PV module carrier and methods of use provide protection for PV modules during transportation, field handling, and assembly with racking systems. The carrier contains elements of a racking system to allow for quicker installation in the field. The PV module carrier reduces manufacturing costs by eliminating the need for frame elements, while reducing field installation time and labor cost for system installation.

An externally threaded fastener is captivated by a component that includes an opening. The externally threaded fastener includes a thread and a non-threaded shaft. The opening includes a major diameter and a minor diameter. The minor diameter includes a first diameter portion, a second diameter portion, and orthogonal portions that connect the first diameter portion and the second diameter portion. To captivate the externally threaded fastener with the component, the externally threaded fastener is positioned within the component opening and the externally threaded fastener is angled relative to an axis of symmetry of the opening in order to engage the threads of the externally threaded fastener with the component opening until the non-threaded shaft is fixed against at least two planes of the component by the first diameter portion of the minor diameter.

A method and apparatus is provided for adjusting a latch. An apparatus comprises a latch body, a first member, and a second member associated with the latch body. A receiving area extends through at least a portion of the latch body. The first member is configured to be at least partially received within the receiving area of the latch body. The first member has a first coupling element. The second member has a second coupling element. Movement of the first member along an axis through the receiving area changes a distance between the first coupling element and the second coupling element.

A robot includes a base, a multi-joint arm provided in the base, and a wrist member configuring a part of the multi-joint arm. The wrist member includes: a motor including a rotor, a rotor shaft, and a stator; and a housing including a motor housing recess, in which the motor is positioned and housed, and forming an external shape of the wrist member. The housing has a motor incorporating recess including a positioning section for the stator, a hole section for fixing the stator incorporated in the motor incorporating recess, and a heat radiation groove section on a sidewall of the motor incorporating recess. A heat radiation member is filled in the heat radiation groove section.

To provide a mounting fixture for a motor driver and a method of mounting the motor driver. A mounting fixture is used for mounting a motor driver on a power magnetics cabinet. The mounting fixture has a rod-like shape of a smaller diameter than multiple mounting holes of the motor driver. For mounting of the motor driver by fixing the mounting holes and multiple screw holes of the power magnetics cabinet with screws, the mounting fixture is inserted in advance into the mounting hole and the screw hole. The mounting fixture is fixed in any screw hole of the power magnetics cabinet. The position of the mounting hole of the motor driver is determined using the mounting fixture. The motor driver is fixed to the power magnetics cabinet with the screws.

A cutting table is provided for supporting flat metal plate to be processed, wherein the support table includes at least one module including: at least two longitudinal end plate members which extend along a longitudinal X axis and are spaced apart a transverse distance Y; and a plurality of spaced apart flat bar members (bar members) which are supported by the end plate members and which span distance Y between the end plate members; wherein the side end plate members and bar members of the module are oriented so that the plane of the end plate members and the bar members all have, in use, a vertical orientation; wherein furthermore in use, the bar members support a sacrificial interlocking grid assembly configured to support the plate to be machined.

A fastener including a chisel point that pre-bores a hole in a work piece to prevent damage to the work piece as the fastener advances. The fastener can include a head, a shaft and a chisel brake point formed at an end of the shaft. The chisel brake point can include first and second opposing inclined surfaces disposed at an angle of about 80° to about 150° relative to one another. A thread can begin adjacent the chisel brake point and form an extension of an inclined surface and/or a chisel edge. The chisel brake point can scrape material from a work piece while pre-boring a hole. The material can be transferred to the thread, and subsequently fed up the thread, out of the pre-bored hole. The chisel brake point can also selectively retard advancement of the fastener into the work piece. Methods of installing the fastener also are provided.

A method and system for permanently attaching a take-up screw for taking-up the axial clearance of the armature shaft of a windscreen wiper motor are disclosed. The take-up screw is screwed axially into a bore in the motor base (SM) until the screw reaches a stop position in relation to the armature shaft locked in the screw. At least one surface discontinuity is provided in the bore and/or the thread of the screw, allowing the screw to be screwed into the bore until it reaches the stop position. The screw is screwed into the bore until the stop position is reached and a screw- and/or motor base-deformation strain is applied at the discontinuity in order to deform the side surface of the screw and/or motor base (SM) and permanently attach the screw and/or motor base by wedging in the discontinuity.

An improved mechanism for retaining screws for a conduit body cover is disclosed. The screws are retained by a layer of PVC lining the inner surface of holes in the cover.

A rotary-drive sub-assembly includes a tool and a tool retainer. The tool includes a fastener-engagement portion, a first threaded portion, and a tool-change-engagement portion between the fastener-engagement portion and the first threaded portion. The tool retainer includes a body and a retaining member. The body includes a symmetry axis, a second threaded portion, configured to be threadably fastened with the first threaded portion of the tool so that the tool is rotationally anchored relative to the body of the tool retainer about the symmetry axis and is translationally anchored relative to the body of the tool retainer along the symmetry axis, and a key, fixed relative to the second threaded portion. The tool retainer further includes a retaining member that is removably coupled to the body at a fixed location.
