Abstract: ABSTRACT OF THE DISCLOSURE         AN IMPROVED SEMICONDUCTOR DIE-ATTACH TECHNIQUE AND COMPOSITION THEREFOR          A method of attaching semiconductor die to a package substrate and a composition for such die attach is disclosed, which method and composition comprise the combination of a low and a high-melting powder with a vehicle consisting of a solvent and a binder so as to form a thick-film ink.  The ink is deposited onto the package substrate and the semiconductor die with a metallized back surface is located in contact with the deposited ink.  The package containing the ink and the die is heated to a temperature of approximately 160°C so as to remove the solvent from the powders and the residual binder. Next, the package is fired at a temperature within the range of approximately 200°C to 430°C so as to melt the low-melting powder which bonds the chip to the package substrate.  Then, a lid is sealed over the die-receiving cavity of the package by heating the package and the bonded die to a temperature within a range of approximately 400°C to 450°C wherein the low-melting powder remelts and the high-melting powder partially dissolves into the liquid of the remelted low-melting powder.

Abstract: MANUAL SEAT RECLINER WITH POSITIVE LOCKING MECHANISM            Abstract of the Disclosure An adjustable recliner mechanism  for manually adjusting  the  forward  and  rearward  position of an automobile  seat back  relative the  seat base  while  a passenger  is  seated  therein.    The  recliner mechanism includes an adjustment arm having an upper end connected to the seat back, a middle portion and a lower end having an arcuate cogged surface.   The middle portion of the adjustment arm is pivotally mounted to a support frame, the  support frame being  secured to the seat base.   A drive gear with a knob to allow manual rotation of the drive gear is mounted to the support frame.   A transfer gear is positioned between the drive gear and the arcuate cogged surface to reduce the torque required to rotate the drive gear to pivot said adjustment arm a sufficient amount so that manual forward and rearward adjustment of the seat back can be accomplished even when a passenger is seated in the automobile seat and exerting a rearward pressure against the seat back.   A clutch assembly is provided for positively locking the seat back in place when the adjustment knob is not being turned.

Abstract: ABSTRACT OF THE DISCLOSURE     A method for adhering a coating material to at least one surface of a densified random-fiber composite sheet is provided.  The method comprises applying heat to a surface of the composite sheet to form an activated surface whereby the fiber component of the sheet is projected outwardly from a plane defined by that surface, and contacting the activated surface with the coating material.  The coating material is generally of a viscous or liquid nature such that it can physically interact with the projecting fibers to adhere thereto.  A method for adhering asphalt to a metal substrate employing a densified random-fiber composite sheet is also provided wherein the metal is coated with an adhesive and then adhered to an activated surface of a composite sheet. Asphalt is then coated onto the exposed surface of the composite sheet which has been activated or is activated by coating with hot asphalt.

Abstract: ABSTRACT     Process for treatment of brown coal which comprises subjecting the said coal to shearing forces to produce a plastic mass which is capable of conversion by subsequent compaction and drying into a fuel  of increased density and enhanced calorific value, is characterised in that the water content of the coal is more than 54% and the shearing forces are applied for less than one hour, shorter times being preferred, for example less than 30 seconds.  A preferred embodiment provides a continuous process in which the coal is treated in a machine that subjects it to sequential steps of shearing and extrusion in a continuous manner.          The extruded product after drying provides the fuel of increased density and enhanced calorific value.  The desired effect may also be obtained by treating part of a quantity of brown coal and blending the treated portion with the untreated remainder of the said quantity.

Abstract: ABSTRACT OF THE DISCLOSURE          In the representative embodiments of the present invention described herein, a new and improved directional drilling tool carrying a rotable drilling bit is dependently coupled to a rotatable drill string for excavating a borehole along one or more selected courses of excavation.  Passage means on the directional drilling tool are communicated with the several fluid-discharge passages in the drill bit.  A rotating flow obstructing member is arranged in the directional drilling tool for selectively communicating the drilling fluid with the bit passages as the drill bit is rotated.  A selectively operable driver is arranged for rotating the flow-obstructing member at one rotational speed when it is desired to sequentially discharge drilling fluid into most, if not all, adjacent sectors of the borehole as the drill bit rotates so as to advance the drill bit along a generally linear course of excavation.  Alternatively, by rotating the flow-obstructing member at a different rotational speed, drilling fluid is sequentially discharged from the bit passages into only a single peripheral sector of the borehole to divert the drill bit to another course of excavation.  Various controls are disclosed for utilizing typical directional measurements to control the direction of excavation.

Abstract: AUTOMATED POSITIONING SYSTEM     Abstract of the Disclosure Automated positioning apparatus for positioning multi-contact components on a circuit board utilizes automated members having a high degree of repetitive movement but not in themselves accurate, such member being relatively inexpensive.  A positioning member picks up a component and moves it over a first viewing head.          The component is viewed and its orientation determined.  A viewing head on the positioning member is then positioned over a target on a circuit board and its position and orientation determined.  The results enable the positioning member to position the component on the circuit board in the correct position and orientation.  The viewing heads are calibrated for aspect ratio and pixel dimension.  Also, the fields of view of the viewing heads are calibrated for orientation relative to the positioning member.  The position and orientation of the viewing head on the positioning member relative to a pick-up member on the positioning member is also obtained.
