Title: Cache with at least two different fill sizes
Inventor: STEELY SIMON C JR
IPC: G06F12/08
Filed: 1989-03-31
Granted: 1993-03-02
Abstract: ABSTRACT            A method and apparatus for optimizing the performance of a cache memory system is disclosed.  During the operation of a computer system whose processor is supported by virtual cache memory, the cache must be cleared and refilled to allow the replacement of old data and instructions with more current instructions and data.  The cache is filled with either P or N blocks of data.  Numerous methods for dynamically selecting N or P blocks of data are possible.  Pursuant to one embodiment, immediately after the cache has been flushed, the miss is refilled with N blocks, allowing data and instructions to be moved to the cache at high speed.  Once the cache is mostly full, the miss tends to be refilled with P blocks, which is less than N.  This maintains the currency of the data in the cache, while simultaneously avoiding writing-over of data or instructions already in the cache.  The invention is particularly advantageous in a multi-user/multi-tasking system where the program being run changes frequently, necessitating flushing and clearing the cache frequently.

Granted: 1994-09-20
Abstract: Abstract of The Disclosure A firefighter's garment which includes a layer of protective material in which the layer of protective material is provided with a major portion which has a high degree of thermal protective properties.  The layer of protective material also has sections which have a lesser degree of thermal protective properties.  The portions of the layer of protective material which have a high degree of thermal protective properties are posi-tioned at locations which require maximum thermal pro-tection.  The portions of the layer of protective material which have a lesser degree of thermal protective prop-erties are located at positions which require less thermal protection.  The portions of the layer of protective material which have a lesser degree of thermal protective properties also have greater flexibility and less bulk and less weight.  Thus, the possibility of stress upon the firefighter is not effectively decreased when fire-fighter body posture during firefighting and the role of the protective equipment is considered.

Title: Image sensing apparatus having automatic focusing function of automatically matching focus in response to video signal
Inventor: KIKUCHI KENICHI
IPC: H04N5/232
Filed: 1989-05-10
Granted: 1993-02-09
Abstract: ABSTRACT OF THE DISCLOSURE    In a video camera having an automatic focusing function, a focus evaluating value is calculated as the sum of first and second focus evaluating values extracted using outputs of two filters having different cut-off frequencies, and a relative ratio of the first and second focus evaluating value is also calculated.  This relative ratio is compared with a predetermined reference value.          Considering a case in which the focus evaluating value is below this reference value after an object is brought into focus, even if the focus evaluating value does not change, an auto-focus operation is resumed.  On the other hand, considering a case in which the relative ratio is above the reference value, even if the focus evaluating value changes, the auto-focus operation is not resumed.  In addition, even if the focus evaluating value reaches a maximum in the auto-focus operation, the auto-focus operation is not terminated if the relative ratio does not reach a predetermined reference value.  Furthermore, the amount of slight movement of a lens in an object change confirming operation after bringing the object into focus is switched depending on the relative ratio.          Additionally, it is determined whether or not the lens correctly moves toward an in-focus position by determining the increase or decrease of the relative ratio.

Title: Method and apparatus for making an asphalt-aggregate pavement
Inventor: BROCK J DON
IPC: B60P1/38
Filed: 1989-07-21
Granted: 1994-04-12
Abstract: ABSTRACT OF THE INVENTION        An apparatus and method for delivering asphalt-aggregate material from a plurality of supply trucks to a finishing machine.  In a preferred form of the invention the hopper of the finishing machine is modified to have a capacity substantially equal to the capacity of one of the supply trucks.  The apparatus is a self-propelled storage vehicle including a hopper having a capacity substantially equal to the capacity of one of the supply trucks, a high capacity loading conveyor, and a high capacity unloading conveyor system.  A transversely disposed screw auger is provided for remixing the asphalt-aggregate material in the hopper prior to its discharge to the finishing machine.  In the first method of operation the storage vehicle shuttles between the finishing machine and a remote location of the supply trucks and in the second method of operation the storage vehicle travels in tandem with the finishing machine as the paving operation is performed.  The high capacity loading conveyor can be equipped with an extendable trough which has a pivotally attached trough floor with front and side plates.  The extendable trough provides a large area which facilitates discharge of paving material from frameless trailers and allows for the early departure of the supply trucks from the conveyor.  The final discharged paving material is gradually emptied from the extendable trough into the conveyor by hydraulic cylinders which tilt the trough to slide the material in the trough into the infeed end of the conveyor.

Title: Surface stripping device
Inventor: KULHAWY NICHOLAS
IPC: E04G23/00
Filed: 1989-09-28
Granted: 1992-07-21
Abstract: Abstract A stripper device for use in removing a covering from a flat surface, such as tile from a floor.  The device includes a elongated member or arm for pushing a blade over the surface, the arm having a connecting portion, for example, at an inner end for mounting on a fork-lift truck.  At the outer end of the arm, there is provided a connector for the blade which is in the form of a disk having a sharp peripheral edge.  The disk includes a mating connector, and preferable, the connectors of the blade and arm are in the form of a ball and socket combination so that the blade can rotate about a vertical axis, and the axis of rotation can vary relative to the arm so that the peripheral edge can lie flatly against the floor at all times.  The disk has a convex upper surface which intersects a lower surface at a shallow angle relative to the horizontal plane containing the peripheral edge.  The lower surface may have a central concave portion surrounded by a narrow annular portion which slopes up from the peripheral edge at an angle which is less steep than the shallow angle that the upper surface.  The ball and socket structure forming the connection between the blade and the arm may be of the type which can be actuated to permit the socket to release the ball so that the device can be readily dismantled.  The device is effective in removing a covering such as tile from a floor surface by pushing the arm across the floor so that a portion of the edge of the blade rotates under the edge of the covering. The device is of simpler construction than known floor strippers which have become complex, usually including a wheel carried frame mounting a motor driven rotating cutter or brush or oscillating blade.
