Abstract: A non-marking web conveyance roller has a generally irregular surface with a plurality of rounded up features that promotes superior venting of entrained air. The surface finish of the roller, formed by a thermal spray process, prevents the formation of impression and honing defects on the conveyed web.

Abstract: A tool for reattaching a leader pin assembly to the data tape of a data tape cartridge utilizes a base that snaps onto the cartridge body. The tool opens the door of the cartridge and the loose leader tape inside the cartridge is laid in an alignment channel. A leader pin is inserted into a set of receptacles over the tape, and a clip is inserted into a pocket within an arm on the tool. The tape is then folded and pulled down over the leader pin and held in the alignment channel with a finger of the user. The arm of the tool, which retains the clip, is then pivoted from a disengaged position to an engaged position. The clip snaps over a center section of the leader pin and the folded tape to form a leader pin assembly, thereby securing the tape in the leader pin assembly.

Abstract: A rigid internal gear 2 of the wave gear device is composed by integrating a tooth-forming ring 12 formed with internal teeth, and a main gear ring 11 into a single body. The tooth-forming ring 12 is manufactured from a ferrous or copper material that has superior strength and abrasion resistance, while the main gear ring 11 is manufactured from a lightweight material, such as an aluminum alloy. The outer circumferential surface of the tooth-forming ring 12 is aluminized to form a dispersed aluminum coating 15, before the tooth-forming ring 12 is cast within the main gear ring 11 so as to integrate the main gear ring 11 and the tooth-forming ring 12. Both parts are reliably integrated so that a large amount of torque can be transmitted, whereby realizing a rigid internal gear that is lighter than conventional models.

Abstract: The present application is directed to methods and systems for improving the operation of transmissions for automotive vehicles, and in particular, the “factory installed” automotive transmission installed by an original automobile manufacturer. The methods and systems modify both the structural components and hydraulic circuitry of an original automotive transmission to adjust applied pressure and shifting patterns to improve the efficient operation of the automotive transmission.

Abstract: Coil members are obtained by forming width-reduced portions in a wire material over a predetermined longitudinal range generally centered on cutting positions, then removing an insulation coating from the width-reduced portions, and thereafter cutting the wire material at the width-reduced portions. Coil segments are prepared by bending the coil members into a general U shape. Then the coil segments are inserted into the slots in a stator core, and a stator is obtained by welding together the free end portions of the projecting coil segments.

Abstract: Core sand elements are rapidly and reliably retained in an assembly by driving one or more smooth surface fasteners, such as staples, nails or brads, into the core elements. Such an assembly method comprises positioning at least two core elements in a core assembly, positioning a smooth surface fastener for entry into the at least two core elements, and driving the smooth surface fastener into the two core elements to fasten them in the core assembly. In such a preferred method, the smooth surface fastener comprises a staple with two smooth surface tines connected by a crown and the staple is positioned for entry of one tine into each of two core elements with the crown of the staple spanning the interface between the two core elements.

Abstract: For an improvement of the coating of disintegrator rolls, an accessory wire in the area of a tooth base is coated with a reduced quantity of hard material granulate as compared to the coating on the tooth. With the proposed coating, the advantage is gained that a precoated accessory wire, without damaging the coating, can subsequently be wound on an accessory wire carrier.

Abstract: A method of assembling a roof assembly into a vehicle includes assembling the roof assembly and at least one module subassembly. The roof assembly includes a roof outer panel configured to cover a roof opening in the vehicle. The roof assembly and the module subassemblies are installed by operators working entirely outside the vehicle, resulting in increased efficiency and production cost savings.

Abstract: A cylinder block production method is characterized by having, as a step prior to a cast-enclosing step of cast-enclosing a cast iron-made cylinder liner within a cylinder block body, an erosion-wash step of washing an outer peripheral wall surface of the cylinder liner and eroding a portion of a base structure of the cast iron forming the outer peripheral wall surface of the cylinder liner so as to form many small protrusions on the outer peripheral wall surface by jetting a high-pressure fluid onto the outer peripheral wall surface of the cylinder liner, in order to improve strength of adhesion between the cylinder liner and the cylinder block body. Since the base structure is partially eroded, complicated-shape small protrusions can be formed. Furthermore, sand and a mold release agent adhering to the outer peripheral wall surface of the cylinder liner can be removed. Therefore, the adhesion strength will improve.

Abstract: A pulley is made by fixing an edge of an opening of a plate by using a first upper mandrel ring installed at a lower end of a first supporting pin of a first forming device. A supporting block is disposed around an upper end of a first spindle and is rotated with the first spindle. An inner nub is formed by inwardly pressing an upper surface of the plate against a first pressing roller to reduce the thickness of the plate while drawing the plate around a first upper mandrel ring. The plate is fixed to a second spindle of a second forming device, so the plate rotates with the second spindle. An outer hub is formed by pressing a convex bead toward the inner hub by using a fourth pressing roller and by drawing the outer hub.

The method may also include controllably moving a welding torch into the air duct and along substantially the length of the recuperator core and controllably welding each butterpass to the air duct along substantially the length of the recuperator core without adding metal to the weld.

Abstract: A process for producing a particle filter from metal foil includes pulling the metal foil from an endless storage device. A joining element or strip is applied to the metal foil. The metal foil is shaped into subsequent channels. The metal foil is wound or stacked to form first and second channels in opposite directions. The first channel has an open entry cross section at the first end side extending partway into the first channel. The first channel has a closure opposite the entry cross section toward the second end side. Mutually bearing contact surfaces of the channels are joined, creating a wholly metal foil particle filter.

Abstract: A method of controlling the spring rate of a spring region of an unassembled or partially or fully assembled load beam for a disk drive head suspension by providing the spring region with a number of bridges which may then selectively opened to achieve a target spring rate. Adjusting the spring rate in this manner provides control of resulting performance characteristics of the head suspension. In one aspect, a data set of spring rate reductions corresponding to bridge sets removed is predetermined and used with the corresponding type of load beam to determine the bridges to remove to approximate the target spring rate.

Abstract: The fastener installation apparatus and method of the present invention include a housing and a moveable body at least partially within the housing. The moveable body defines a plurality of openings and is fixably attached to at least one piston, which is in moveable contact with the housing. First and second cavities are defined on opposite sides of the piston and respective openings in the moveable body are in communication with opposite sides of the piston. In addition, a valve directs a fluid through the appropriate openings in the moveable body and into the first cavity or the second cavity, as desired, which, in turn, alternately extends and retracts the moveable body relative to the housing. A jaw extends from the housing in alignment with the moveable body, such that the jaw and the moveable body cooperate to install a fastener upon extension of the moveable body.
