Abstract: DIVISION METHOD AND APPARATUS INCLUDING USE OF A Z-Z PLOT TO SELECT ACCEPTABLE QUOTIENT BITS                     ABSTRACT OF THE DISCLOSURE           An optimized division circuit and a method of implementing the circuit includes the steps of determining a Z-Z plot relationship which represents a relationship between a first divisor ratio proportional to a range of previously determined remainder values divided by the divisor and a second divisor ratio equal to a range of succeeding remainder values divided by the divisor. A complete look-up table is automatically built from the Z-Z plot relationship which includes, for each different valid combination of divisor and next remainder values, either a corresponding quotient digit or a DON'T CARE indicator. A state value, used in the logical implementation of the circuit, is then assigned to each different quotient digit. The circuit includes a divisor multiple formation circuit, a quotient determining circuit and a quotient assimilation circuit. The divisor multiple formation circuit includes a divisor multiple multiplexer. The quotient determining circuit includes a next partial remainder determining circuit and a next quotient digit selection circuit. The quotient assimilation circuit subtracts negative values of quotient digits from positive values to determine a final quotient value.

Abstract: A method of image conversion takes an original print ready image at a first resolution scaling and orientation, and simulates printing that image by creating a representation of a page at the particular resolution, scaling and orientation. The image is then periodically sampled through the page with an aperture that corresponds to the desired output. Because the resolution, scaling and/or orientation of the "print" and "scan" are distinct, the aperture "sees" areas which may correspond to more than a single pixel on the original image, and thereby may derive a signal that is gray, i.e., the aperture may see an area that is neither completely black or white, and the image data derived will be considered gray. The gray image data, which may be definable at several bits per pixel, is then made print-ready by reducing the number of bits defining each pixel to a valid output state (0, 1 for a typical binary printer, 0, 1, 2, 3 for a quaternary printer, etc.). The reduction step is accomplished through error diffusion methods that maintain the local area gray density level. In color applications, each of the bitmaps representing a color separation, be it 2, 3, 4 or any other number, is treated independently with the same method.

Abstract: A  magnetic  disk  device  having  a  floating-type magnetic head, for use with a disk-shaped recording medium having a sliding area for the floating-type magnetic head formed outside a recording area.  The length in the disk radial   direction   of   a   suspension   supporting  -the floating-type  magnetic  head  is  varied  depending  on individual magnetic disk devices.  In another arrangement, a control means is  provided for  setting two reference values  so that a radial position of the  floating-type magnetic head detected by a detection section is compared with these reference values, and for alternating one of the preset reference values to the other reference value upon receiving a rotation stop signal.  In still another arrangement, control means is provided, whereby a radial position for sliding of the floating-type magnetic head is randomly varied within the sliding area.   According to these arrangements, since the radial position for sliding of the floating-type magnetic head is varied within the sliding area without being located at the same position, abrasion within the sliding area can be dispersed.  As a result, it becomes possible to extend the longevities of the floating-type magnetic head and the recording medium.

Abstract: ABSTRACT The invention pertains to a liner made of elastic, deformable, flexible material. By the special design of the contours in the area of its opening, shoulder, sides, and its bottom, the liner is intended to be so firmly attached to a top, that the assembled components can be handled, stored, and transported as a single unit. The liner, by its quality and form is, by vacuum, completely contracted in the moment of its pneumatic attachment and will be fixed at the top and oriented to its intended resulting shape and direction. Such a liner is used in connection with the manufacturing of a valve liner unit which is intended to be used in a pressurized container. With this valve liner unit, it is possible to easily manufacture a pressurized container by a method according to which the container is first pre-pressurized with compressed air or other compressed gases, while the filling goods make no contact with the inner walls of the container and whereby it is not necessary to create an additional opening to the container instead of the one opening for inserting the valve liner unit. The filling goods can be introduced into the pre-pressurized container according to this method without contact with environmental air.

Abstract: A cellular telephone includes a speed dialing memory and a current location memory. International access codes respectively identified by corresponding country codes are stored in an access code memory. An indication of the current location of the telephone is stored in the current location memory. A destination address number is retrieved from the speed dialing memory in response to entry of a speed dialing code through a keypad when a call is originated. The country code of the retrieved number is compared wlth the stored location indication to detect a match or a mismatch. A first decision is made that the originated call is an international call if a mismatch is detected, or a second decision is made that the call is domestic if a match is detected. In response to the first decision, an international access code is retrieved from the access code memory corresponding to the stored current location indication and appended to the retrieved address number, and in response to the second decision, the country code of the retrieved address number is replaced with a digit "0".

Abstract: PATENT 390100.2619 Abstract of the Disclosure A digital video tape recorder includes a rotary drum that has a leading head and a trailing head mounted thereon for recording video signals in respective slant tracks scanned on the tape while the tape is advanced.  Each of the tracks includes, in sequence in the scanning direction of the respective head, a first auxiliary recording area, a second auxiliary recording area and a video signal recording area.  The heads are displaced with respect to each other on the drum in the scanning direction by a distance that is less than the distance in the scanning direction between an ending edge of the first auxiliary recording area of the track formed by the trailing head and a starting edge of the video recording area of the track formed by the leading head.          Because of the arrangement of the heads, after-recording of audio signals in the first auxiliary recording area by the trailing head is completed before the leading head begins reproduction of video signals.  This prevents cross-talk from the audio recording signal that would disrupt the reproduced video signal.  A satisfactory picture can therefore be reproduced during after-recording of audio signals.     i

Abstract: Important intermediates for preparing cephalosporin antibiotics, 7-amino-cephalosporanic acid (7-ACA) and 7-aminodeacetylcephalosporanic acid (7-ADAC), are prepared by a novel bioprocess in which a transformed Penicillium chrysogenum strain is cultured in the presence of an adipate feedstock to produce adipoyl-6-APA (6-amino penicillanic acid); followed by the in situ expression of the following genes with which the P. chrysogenum has been transformed: 1) an expandase gene, e.g., from Cephalosporium acremonium, whose expression product converts the adipoyl-6-APA by ring expansion to adipoyl-7-ADCA; 2) an hydroxylase gene whose expression product converts the 3-methyl side chain of adipoyl-7-ADCA to 3-hydroxymethyl, to give the first product, 7-aminodeacetylcephalosporanic acid (7-ADAC); and 3) an acetyltransferase gene whose expression product converts the 3-hydroxymethyl side chain to the 3-acetyloxymethyl side chain of 7-ACA.      The final product, 7-ACA, is then prepared by cleavage of the adipoyl side chain using an adipoyl acylase. The entire synthesis, accordingly, is carried out using bioprocesses, and is efficient and economical.
