Abstract: A method and apparatus for processing a magnetic transducer which uses gallium ion beam milling to precisely define pole tip widths of the magnetic transducer. The gallium ion beam may be defocused to improve definition of the region which is damaged by gallium ion implantation. The precision pole tip widths provide a transducer that may record correspondingly precise track widths on a magnetic storage medium, such as a rotating disk. Subsequent to the ion milling process, the invention restores the magnetically conductive properties of the pole tip region, which may be degraded as a result of the ion milling process, by means of a lapping process.

Abstract: A method and apparatus for applying travelers to a ring of a fiber processing machine. A traveler applicator includes a traveler rail on which travelers are urged by a pusher towards a reciprocating traveler tooth. Actuation of a trigger causes the traveler tooth to engage a traveler from the traveler rail and to advance it outwardly for attachment to a ring. Release of the trigger causes the tooth to retract and allows clearance between the tooth and the next traveler positioned on the traveler rail for dispensing. Upon full retraction of the tooth, the tooth advances inwardly to engage the next traveler on the traveler rail. A spring-biased engagement member contacts the traveler to secure it on the tooth. A cartridge having a plurality of traveler-holding rails about its periphery feeds travelers to the traveler rail. Once a cartridge rail is depleted of travelers, the cartridge is rotated such that the next rail having travelers is presented to the traveler rail for dispensing.

Abstract: New application of biomechanical principles of elastic stretch and braking force are combined in an athletic shoe. The new design implements the concepts by placing the heel of the shoe inner sole significantly lower than the ball of the foot and toes. Tests show that an inner sole reverse slope of about 31/2.degree. provides an optimum significant improvement in jumping in particular. The reverse slope is substantially flat from the center of pressure beneath the heel to the five centers of pressure beneath the ball of the foot. The flat slope provides more assurance that the weight of the user will be applied to the shoe through the centers of pressure in preference to locations under the arch. The invention is applicable to "explosive" movement sports such as basketball, track and field, volleyball, tennis and soccer. Preferably the shoes are constructed with formed or curved heels to retain the feet properly positioned in the shoes by preventing the feet from sliding too far back within the shoes.

Abstract: An area where a front device 1A is movable is set in advance. A target speed vector of the front device is modified such that its component in the direction toward a boundary of the set area is reduced, by using signals obtained by reducing operation signals input from control lever units 4a-4c when a mode switch 20 is turned on and the front device is within and near the boundary of the set area, and by using the operation signals as they are when the mode switch 20 is turned off. When the front device is outside the set area, the target speed vector is modified so that the front device is returned to the set area. Thus, excavation within a limited area can be performed efficiently and smoothly, and an operator can select one of an accuracy precedence work mode and a speed precedence work mode at his own discretion.

The swing movement control mechanism comprises a swing movement control plate shiftable along the crank arm so that the connecting arm which is also pivoted on the swing movement control plate can be connected to a gate having a desired swing or so-called "throw".

Abstract: A reinforcing channel-shaped carrier for a sealing, trimming or guiding strip is made of metal and provided with slots of several different types. Slots of a first type extend across the base of the carrier and for short distances into the side walls and facilitate bending about an axis parallel to the base and perpendicular to the length of the channel. Slots of a second type are positioned in the side walls and facilitate bending about an axis perpendicular to the plane of the base. The latter slots are of two different forms. Slots of one form are shorter than those of the other form. This increases the stiffness of the carrier. The carrier is produced by slitting a flat metal blank and then rolling it along stretch paths to cause it to be thinned-down and expanded lengthwise to convert the slits into slots. The carrier is advantageously used in a sealing, trimming or guiding strip in closed loop form ready for fitting to a vehicle door opening.
