Title: Transaction approval system
Inventor: BOGGAN ELVIS W
IPC: G07F7/08
Filed: 1990-01-05
Granted: 1994-05-24
Abstract: ABSTRACT OF THE DISCLOSURE         An improved system is disclosed for detecting invalid transaction cards at remote transaction terminals.  The system includes providing each terminal with a master table having data corresponding to invalid cards.  The data in the master table is less than the actual account numbers of the invalid cards.  By using a compressed version of the data, the file can be shortened to facilitate storage and transmission.  The compressed data file is arranged such that when an invalid card is presented, it will be identified and routed on for further processing.  In the preferred embodiment, the probability that a valid card will be identified as potentially invalid is on the order of one to three percent.  During each transaction, the master table is supplemented with information about the account number of the transaction card presented for the purchase.  In this manner, any subsequent use of the card will be routed for additional processing.  A scheme for compensating for data transmission errors is used to reduce the possibility that information about invalid cards is not lost when the master file is distributed.

Title: Highly efficient method for calculating rotational speed
Inventor: BLACKWELL ANDREW K
IPC: B60T8/1761
Filed: 1990-01-15
Granted: 1993-10-12
Abstract: HIGHLY EFFICIENT METHOD FOR CALCULATING ROTATIONAL SPEED         Abstract of the Disclosure A process for maximizing the instruction processing efficiency of a digital computer for the purpose of calculating rotational speed wherein the calculation of speed is based upon speed signals generated by a tachometer.   By (1) counting the quantity of the speed signals received during a fixed sampling period, and (2) recording the occurrence time of these speed signals only as necessary for the calculation of rotational speed, the invention improves over known methods in that it does not record the occurrence time of all speed signals, but rather records the occurrence time of only those speed signals necessary for the calculation.  The invention accomplishes this by a) anticipating when the speed signals necessary for the speed calculation will be generated (and subsequently received by the digital computer) and b) recording the occurrence times only when it is anticipated that these necessary edges will be received by the digital computer.

Abstract: The present invention relates to an agricultural machine comprising at least one group of working members (19) and a structure (14), to which said group (19) is connected by means of a suspension device (22). The latter is structured in such a way that the group of working members (19) can:

  - pivot about the straight line (72) 
 
<??>In contrast, because of the lateral suspension members (60, 66), the group of working members (19) cannot pivot about the straight line (75). In the invention, it is also possible to ensure the pivoting of the group of working members (19) about the straight line (74) is prevented or at least limited.

Inventor: MURAKAMI YOSHITERU
IPC: G11B23/00
Filed: 1991-05-02
Granted: 1997-06-24
Abstract: A magneto-optical disk has a substrate whereon a recording medium is formed, and a depression is formed on the substrate on the inside of the recording medium of the substrate. A center hub is installed on the depression such that the center hub is substantially level with a protective- resin layer covering the recording medium. On the center hub, a flying head performs CSS (Contact-Start-and-Stop). This configuration of the disk eliminates the occurrence of dust due to abrasion and head crash, and achieves stable CSS. A method of manufacturing the magneto-optical disk is also disclosed, wherein the protective-resin layer is formed after installing the center hub on the depression. In this method, since a space is not produced between the center hub and the protective-resin layer, stable flying characteristics are obtained. And a magneto-optical disk is disclosed, whereon small physical bumps and pits are formed on the substrate on the inside of the recording medium, which prevents the flying head from sticking to the disk. A method of manufacturing the magneto-optical disk by using a stamper, which permits the disk to be mass-produced, is also disclosed.
