Patent EP-0297634-A2 (EP)
Inventor: KULAKOWSKI JOHN EDWARD
IPC: G11B7/00
Filed: 1988-05-19
Abstract: A data recorder, preferably of the magnetooptic type, employs a rotating record storage disk (30). The record storage disk has a track starting primary data storing sector circumferentially adjacent to the track starting sector or a small plurality of alternate data storing sectors which are not addressable directly by mechanisms outside of the recorder as are the primary recording sectors. Whenever a one of the primary sectors in a given track is found to be defective, then one of the alternate sectors in that same track receives data from a one of the primary storing records of sectors in the same track. A small number of alternate sectors are selected to extend circum­ferentially for creating an elapsed scan time over the element of sectors not less than the elapsed time required for the recorder to switch from scanning one track to scanning an adjacent one of the tracks. In a magnetooptic recorder, the elapsed time selected for scanning the small plurality of alternate sectors is also not less than the time to reverse the magnetic biasing field for erasing and recording on the disk. Alternate sectors provide both for alternate data storage and for the preparatory steps of track jumping or switching and magnetic field bias reversal. Second alternate ones of the tracks are selected in the event all of the alternate sectors in a given track are filled with data from defective ones of the primary sectors in the same track as the alternate sectors.

Abstract: Method for use in a CAD system whereby three-dimensional interferences among space-oriented objects can be rapidly determined by storing a reduced granularity of the design space in the form of a three-dimensional matrix having elements (10) which represent identification numbers of objects which occupy the design space in the subcontinuum represented by the element. The element can be multidimensional or the element can refer to a table if more than one object occupies the associated subcontinuum. As objects are added to the drawing, the new objects are assigned unique index numbers which are stored in all the matrix elements corresponding to all the subcontinuums occupied by the object. Calculations for interference among pairs of objects need only be made between objects having their index number in a same element of the matrix.

Abstract: Disclosed is an improvement of gaslighter structure which has, in the hollow cylinder space at the rear portion of the housing, a push rod having hooks integrally connected to its op­posite sides. The push rod is spring-biased upwards, and is pushed against the support piece of the cap, thereby permitting the cap to click shut and open. This arrangement permits neces­sary parts including a spring to be assembled in a cap pivot-and-­latch simply by thrusting them in the rear space of the housing. This reduces the difficulty which otherwise, workers would en­counter in assembling parts including a resilient element in a relatively small space. Also, the work of pivoting the cap to the housing can be advantageously separated from the work of as­sembling pivot-and-latch parts.

Abstract: A DRAM test system includes a storage location tester and controller tester. The storage location tester utilizes an error correction code which generates redundancy symbols corresponding to inverted data that are the binary inverse or compliment of the redundancy symbols corresponding to the non-­inverted data. Thus each bit-location of an addressable storage location, consisting of both data and ECC redundancy bit locations, can be fully tested for storage and retrieval of both a ONE and a ZERO in only three read/write cycles. The controller tester tests the DRAM controller circuitry by sequencing it through various operations, at least one of which is a refresh operation. When a refresh operation occurs the node signals corresponding to the refresh operation are incorporated into a DRAM controller signature vector. To counter the effects of the refresh operation on the signature vector, a refresh-vector is applied to the signature vector register during the refresh operation and the contents of the register are updated. This results in the contents of the signature vector being "returned" to the pre-refresh contents at the end of a properly executed refresh. At the completion of the testing cycle the signature vector may then be compared with the expected output vector, which does not include any refresh operation information, to determine if the DRAM is functioning properly.

Abstract: A compensation winding for improving the linearity of a displacement transducer. The displacement transducer is the type having an electrically conducting non-­ferromagnetic wall which moves in telescoping relation with the coil and is excited by a signal at a suffi­ciently high frequency that skin effect on the wall permits displacement of the wall to vary the reluc­tance of the coil flux path and thereby vary its in­ductance proportionally to displacement of the wall. The compensation winding is wound in telescoped, co­axial relationship to the coil in a fixed position. The compensation winding has a pitch which is a decrea­sing function of the distance from the end of the coil which is the nearest the wall when the wall and the coil are in their least overlapping relationship.
