Patent CA-2025432-C (CA)
Title: Bearing apparatus and method for preloading bearings for rotary - vibratory drills
Inventor: ROUSSY RAYMOND JOSEPH
IPC: E21B7/24
Filed: 1990-09-19
Granted: 1997-11-25
Abstract: A vibratory apparatus includes an outer member with a central opening. An inner member is within the opening of the outer member.  There are two sets of bearings between the outer member and the inner member for permitting relative rotation therebetween about an axis. The two sets of bearings are spaced apart along the axis, each having an inner race and an outer race.  The inner races are slidably mounted on the inner member.  A portion of the outer member is disposed between the outer races so as to hold the outer races a first distance apart and so the inner races are held a second distance apart when the inner member and outer member are unloaded.  Each of the sets of bearings transfers from the inner member to the outer member those forces acting along the axis which are directed towards the other set of bearings only.  There is a spacer disposed between the inner races.  A nut connected to the inner member biases the inner races towards each other along the axis with a force which has a first component transmitted from the inner member to the portion of the outer member by the sets of bearings and a second component which is borne by the spacer.

Title: Method for recognizing the leading edge of a character in e13b font
Inventor: FRANKLIN GENE R
IPC: G06K7/00
Filed: 1990-10-29
Granted: 1995-12-26
Abstract: A method for locating the start of a MICR character in E13B font so as to facilitate character recognition.  A Calculated Character Start Position (CCSP) is generated by using a predetermined number of voltage samples corresponding to a portion of MICR waveform generated by reading a MICR character on a document.  The CCSP is generated by averaging the predetermined number of voltage samples within the window which tends to minimize the harmful effects of noise.  Noise from magnetic ink spatter is sometimes wrongly interpreted as the start of a character.  A process of "jiggling" is used to assist character recognition techniques by utilizing different character start positions to determine whether or not a template match in character recognition techniques occurs when the new or different character start position is used.  Dynamic thresholding is used to avoid false starts or "ringing" due to an immediately previous character which was read having a high intensity waveform compared to the normal intensity expected.  The method also employs a technique of having a variable starting point for the search for the start of the next character, with the variable starting point being based on the character just recognized.

Granted: 1996-02-20
Abstract: An information recording and reproducing apparatus employs   a   magneto-optical   disk   including   a   main information recording area wherein plural pieces of main information can be recorded and a TOC area wherein control information related to each piece of main information can be  recorded.   When a  reproducing  operation  cannot  be performed from the TOC area, it is checked whether or not any pieces of control information exist, for example, by detecting  an  amplitude  of  a  reproduced  signal.   Or, whether or not a recording or reproducing function of the apparatus works properly may be checked by, for example, a method of test writing and reproduction.  As a  result, whether or not the magneto-optical disk is a blank disk can be accurately determined.  Further, when the disk is determined to be a blank disk,  distinctive information indicating a blank disk is recorded in a predetermined portion of the TOC area.   Thereafter,  upon loading the disk, the disk is promptly determined to be a blank disk.          On the other hand, when the disk is not determined to be a blank disk, at least a recording operation is inhibited, thereby eliminating a possibility of  destroying useful main information already recorded in the main information recording area.
