Abstract: The present invention relates to a method of forming a diffused region with a shallow junction having a refractory metal silicide layer thereon. At first, the refractory metal silicide layer is selectively formed on a silicon substrate of one conductivity type. An insulating film is then formed at least on the refractory metal silicide layer, and a contact hole is opened on a part of the silicide layer. After necessary high temperature treatments have been conducted, a dopant impurity of the opposite conductivity type is introduced from the contact hole to the silicide layer. The impurity is laterally dispersed in the silicide layer and diffused into the whole portion of the silicon substrate in contact with the silicide layer, whereby the diffused region with a shallow junction can be formed.

Abstract: A process for making a CMOS dual-well semiconductor structure with field isolation doping, wherein only a single lithographic masking step is required for providing self-alignment both of the wells to each other and also of the field isolation doping regions to the wells. The lithographic masking step forms a well mask and defines an oxidation barrier which acts as: an implant mask (absorber) during the ion-implantation of a field dopant of one type; an oxidation barrier over one well during the oxidation of the opposite-type well to form over the one well a sacrificial oxide layer which forms the alignment marks for subsequent formation of the field-doping regions; and a dopant-transmitter during the ion-implantation of an opposite-type field dopant which is simultaneously absorbed by the sacrificial oxide. As a result, there are formed field-doped oxide layers self-aligned to the wells so that, with a subsequent masking step, oxide field isolations are defined over the doped oxide layers.

Abstract: A method and apparatus for drying stored grain based upon phenomena related to wet bulb temperature, depression, relative moisture, and relative humidity. The invention contemplates a conventional grain storage bin in which a suitable storage volume is defined beneath a lower, preferably perforated floor. A lower air plenum defined beneath the floor receives air which is circulated through the bin to dry the stored grain. When activated a relatively low capacity gas heater heats the circulating air which is forced by a conventional fan through an interconnecting vent interiorly of the bin plenum. Fuel for combustion preferably is limited by a modulating valve controlled by a temperature-sensing probe disposed within the plenum. Operation is initiated by a humidistat disposed exteriorly of the plenum, which initiates heating in response to ascertainment of a control reference humidity. For drying purposes the temperature of ambient air is raised by no more than the control depression.

Abstract: A pneumatic rotary grinding tool in which the motor unit (15) is displaceable between a rear, operative position and a forward, dislocated position. A safety guard (18) mounted on the tool housing (10) forms an axial support for the motor unit (15) to keep the latter in a rear, operative position, thereby maintaining a seal (23-25) in active position to prevent supplied pressure air from passing directly from the supply passage (12) to the exhaust passage (35) without energizing the motor unit (15). When the safety guard 18 is removed the motor unit (15) is dislocated by the air pressure to a forward position in which the seal (23-25) is rendered inactive and allows supplied pressure air to pass directly from the air supply passage (12) to the exhaust passage (35).

Abstract: A knife sharpener includes an elongated sharpening element held within a tray that selectively telescopes within one end of a handle to store the element. The handle has a forward surface that lies in an inclined plane and approaches the sharpening surface of the extended sharpening element at the correct angle for sharpening the cutting edge of a knife blade so as to provide a sharpening guide. The tray and handle provide a thumb-operated, bolt-action device for extending and retracting the tray and its sharpening element, for locking the tray in its extended and retracted positions, and for selectively releasing the tray from its locked positions. The sharpening element may be a block of ceramic abrasive material surfaced on one face with a diamond-studded cloth to provide a coarse abrasive sharpening surface and longitudinally grooved on an opposite face to provide a fine abrasive honing surface.

Abstract: A machine for sharpening the blade of an ice skate has a vertically mounted, thin grinding wheel with a convex transverse cross-section corresponding to the concave transverse cross-section desired for the blade edge. Clamping plates on a cradle hold the blade above the wheel with their central planes coplanar and with the wheel biassed against the blade. The cradle is pivotable about a horizontal axis above the skate so that the skate can be swung in an arc. Hence the movement of the blade over the wheel takes place in an arc that is curved in the same direction as the convex profile of the blade edge. This action reduces the problem of unevenness of depth of cut along the length of the blade, that has been experienced with prior machines employing straight line relative travel between the skate and the wheel.

The sanding disc can be strongly secured to the backup pad but can be pulled away from it, leaving the feathering adhesive on the backup pad.

Abstract: A non-displaceable, self-righting shim for use in any application where critical alignment is required of adjacent vertical elements. The shim presents an elongated central opening including a large upper portion and a small lower portion, and a slot having an exit end communicating with the central opening and an entrance end at the perimeter edge of the shim. The weight distribution of the shim relative to the large upper portion is such that the shim will hang in a normal upright position with the small lower portion and the slot below the large upper portion. The arrangement assures positive placement of the shim once installed; avoids loosening and fall-off of the shim which may be caused by thermal expansion and contraction of the shimmed element and/or by vibrations associated with the adjacent vertical elements; and eliminates the need for holding the shim in position while securing the fastener.

Abstract: The exposed edge of a planar surface of an article of furniture, such as a desk or tabletop, is trimmed with an elastomeric edge molding. Two projections or flanges extend longitudinally along the inner surface of the molding. One projection, a centrally located mounting flange, is inserted into a longitudinal groove cut into the furniture top edge. The molding is securely attached to the furniture top by inserting the mounting flange into the longitudinal groove. The other projection, a locator rib, is located near the edge of the molding which must be flush with the furniture top surface, between that edge and the mounting flange. The locator rib is inserted into a longitudinal groove cut into the furniture top edge. Positioning the locator rib near the molding edge reduces the dimensional tolerances which are inherent in extruded elastomeric moldings.

Abstract: A rotary application head for applying a screw-threaded closure to a container includes a collet 26 for gripping the closure, the collet being secured to a drive member 31 having an external flange 36 disposed between a thrust bearing 37 supported by the main body 10 and a friction clutch plate 38 backed by a pressure plate 40 which is driven by the body through pins 42. A piston 17 disposed in a pneumatic cylinder 16 in the body acts through push rods 19 to apply a predetermined axial loading between the pressure plate 40, friction clutch plate 30 and the flange 36. When the closure reaches a predetermined tightness, the reaction torque causes the collet and drive member to slip relative to the pressure plate and body, preventing over-tightening of the closure. External axial forces applied to the collet cause the piston 17 to be displaced axially to compensate for these forces without altering the torque at which slipping occurs.
