  • Publication number: 20020133923
    Abstract: A fiber structure for needling is driven so as to impart a speed of advance thereto past a needling head carrying a plurality of needles that are driven with reciprocating motion during which they penetrate into the fiber structure and are extracted therefrom. The instantaneous speed of advance of the fiber structure decreases in response to the resistance to advance caused by the needles penetrating and subsequently increases on the needles being withdrawn. The force exerted on the needles by the advance of the structure is thus limited, without completely interrupting advance throughout the time that needles are present within the structure. The fiber structure can be caused to advance by means of a transmission presenting mechanical slack suitable for absorbing the decrease in the speed of advance caused directly by the resistance to advance that is exerted by the needles.

    Abstract: A method of producing plural device chips from a thin plate of a pyroelectric material comprises the following steps. First, plural device-forming regions each having an electrode and a circuit pattern for electrically connecting the electrodes are formed on each of front and rear surfaces of the thin plate to obtain a device substrate. By making an electrical connection between the circuit patterns, and grounding it, all of the device-forming regions on the device substrate are at the same potential. Next, a blast treatment is performed to the device substrate to remove a required region of the pyroelectric material, while leaving a bridge portion extending between adjacent device-forming regions and having the circuit patterns thereon, so that a device-chip aggregate is formed, in which adjacent device chips are coupled through the bridge portion. Subsequently, by removing the bridge portion, the device chip is separated from the device-chip aggregate.

  • Publication number: 20020133934
    Abstract: The present invention is a method for determining a characteristic of a magnetic head during its fabrication process on the surface of a wafer substrate. The method involves the fabrication of a test magnetic pole artifact in a field area of the substrate surface adjacent to the actual magnetic pole that is being fabricated. A test pole structure is fabricated simultaneously with the actual pole utilizing the same fabrication conditions and parameters, such that the test pole is nearly identical to the actual pole. During a field etch step undertaken in the fabrication of the actual pole, portions of the test pole structure are removed, leaving a test pole artifact on the wafer surface. The test pole artifact can be easily measured as an accurate indication of characteristics of the actual magnetic pole that are difficult to measure directly, thereby saving time and expense in the magnetic head fabrication process.

    Abstract: Apparatus and method precisely preload bearings onto shafts. A swivel plate swivels up to 360° and locks a rotary shaft axially with a motor shaft. A shim and bearing adjacent the shim preload onto shaft shoulder by lock nut secured to the threaded shaft. The lock nut forces the bearing inner race to expand outwardly, preloading the bearing. A force sensor measures torque on the bearing outer race. Measured torque is monitored within a predetermined range to establish the precisely loaded bearing. The method slides a shim onto support shaft shoulder. A bearing is slid onto tapered surface, and lock nut tightened onto the threaded shaft. The lock nut expands the bearing inner race, reducing the distance between the inner and outer races and preloading the bearing. The outer race at a predetermined, constant speed has torque monitored to a predetermined range to provide a precisely preloaded bearing.

  • Publication number: 20020133952
    Abstract: The invention provides a blade guard comprising an elongated member of resilient material that has a longitudinal axis. The member has a portion of an outer surface extending parallel to the longitudinal axis and spaced from the axis. An elongated slit defined in the member includes slit walls defined by the resilient material. The slit extends in a plane extending from the portion of the outer surface inwardly of the member and parallel to the longitudinal axis. The member is adapted to engage the blade of a knife within the slit of the member and the resilience of the material of the slit walls is sufficient for the member to be held on the blade so as to cover a portion of a cutting edge of the blade.

  • Publication number: 20020133956
    Abstract: A method and apparatus for a blade clamping mechanism in a woodworking plane that allows a plane iron as wide as the plane body itself to be clamped in a wedge shaped slot in the plane body. The slot begins at a point tangent to a waste ejection hole proximate a front area of the plane running diagonally towards the spine of the plane body before looping back short of the spine to return diagonally through the sole forming the mouth together with the waste hole. The loop forms the widest point of the slot, while the tangent forms the narrowest point of the slot. The rear surface of the slot serves as the ramp for the plane iron. The plane iron is clamped by a floating pin mounted in a hole drilled longitudinally through the spine, perpendicular to the ramp, and terminating at an inspection hole. The floating pin is retained between the under side of the plane iron and a conical shaped point of a screw threaded from a back of the plane body diagonally to the floating pin.
