A divided storage system is formed of a collapsible container and a collapsible divided file assembly. The container includes a planar blank having a centrally-located bottom panel with four side portions, four side panels each foldably attached to a respective one side portion and movable to a position perpendicular to the bottom panel fasteners are carried by each side panel for attaching the side panels together to define an interior space. The file assembly includes files each locatable adjacent to the side panel and removably attachable thereto. The file assembly includes a plurality of file dividers located between the first and second files and are connected via accordion pleats. The first and second files include outwardly extending tabs with passageways therethrough and are attached to the container by being sandwiched between the respective end and side panel at each of the four corners of the assembled container.

This invention includes a reticle used for making a semiconductor device in a photolithography process. The reticle has a device exposure region having sides and a device pattern within an area defined by the sides, an opaque chrome region disposed adjacent to the device region, and a kerf region surrounded by the opaque chrome region, the kerf region being offset from the sides of the device exposure region by the opaque chrome region. The reticle should facilitate a double exposure method of a photolithography process by interleaving adjacent exposures of a wafer during the photolithography process, while allowing the single exposure of the respective kerfs.

A motor stator 400 is integrated with a position sensor 200 through a novel attachment ring 600. Electrical connection to the integrated device is through terminals 202, 210 that pass through the position sensor housing 250. The stator 400 is preferably overmolded, though other suitable forms of encapsulation are contemplated. The attachment ring 600 is preferably ultrasonically bonded to the sensor 200 during manufacture, prior to insertion of the motor armature 430. Other methods of attachment arc contemplated, and various types of motors and sensors are also contemplated.

A wireless power line carrier voice and data communication device is provided. The device permits a user to connect a caller identification unit to a telephone extension whose only connection to a telephone line is over an AC power line. The invention provides for appropriate amplification, joining with other audio paths, and transmission while requiring no hardware modifications of the extension unit or the wireless extension jack.

Self-bondable polyamides are prepared by reacting an aromatic diisocyanate or diamine with a mixture of terephthalic acid and an aliphatic dibasic acid having at least 6 carbon atoms. These self-bondable amides can also be used as topcoats for wires having basecoats of another polymer, e.g. a polyester, polyester-imide, or polyamideimide.

The modular wrench with extendible shank includes at least one stubby wrench head segment having either an open end or a box end wrench head, and a truncated shank extending from the wrench head. A short connector sleeve having sockets defined in both ends that frictionally receive the truncated shank of the wrench head segment is provided so that two wrench heads may be attached to opposite ends of the sleeve to form an open end wrench, a box end wrench, or a combination wrench of standard size. Two elongated extension bars, e.g., a six-inch and a ten-inch bar, are provided, each extension bar having a stub projecting from one end that frictionally fits into the connector sleeve, and a socket defined in the opposite end that frictionally receives either the truncated shank of the wrench head or the stub of the other extension bar.

A system for communicating signals between a transmitter and a receiver using digital modulation techniques is provided. This invention is particularly adapted to meet the requirements of power line communication. In one preferred embodiment of this invention the modulation technique is differential binary phase shift key modulation. This system provides a low cost, simple delay and multiply process for the modulation and demodulation of data. This system lends itself to an ASIC implementation, thereby further reducing the cost of the system while improving the reliability of the system in a noisy environment.
