Title: Magnetic head and a digital recording magnetic head
Inventor: OGATA SEIICHI
IPC: G11B5/265
Filed: 1992-03-27
Granted: 2001-05-29
Abstract: A magnetic head comprises a head base (56), and a pair of magnetic head chips (57, 58) of different azimuth angles (.theta.1, .theta.2) disposed on the head base (56). The pair of magnetic head chips (57, 58) are disposed in a stepped arrangement with respect to the direction of arrangement of tracks on a magnetic recording medium with a step (DA) substantially equal to the pitch (P) of tracks on the magnetic recording medium. The gap distance (GL) between the magnetic gaps of the magnetic head chips (57, 58) is shorter than the sum of the length (L) of interblock gap regions between video signal regions and audio signal regions arranged along the direction of movement of the magnetic head, and the step (D) between the adjacent tracks on the magnetic recording medium. The magnetic head enables satisfactory after-recording and the long-time recording reproducing of digital video signals tin the magnetic recording medium even if the magnetic recording medium is a narrow magnetic tape of 8 mm or below in width.

Abstract: An information recording and reproducing apparatus having a motion controller for an optical head capable of moving the optical head to a target position in a short time  while  eliminating  an  error  to  be  caused  by mechanical elements and without reading a present address during the motion of the optical head from a far jump to a  near  jump.    In  the  information  recording  and reproducing  apparatus  for  an  optical  information recording  medium  for  recording  and  reproducing information to and from the medium by scanning a light beam from the optical head to a track, the motion of the optical head is controlled by a combination of a far jump driving  the  optical head and a  near  jump driving  an objective lens assembled with the optical head.   During the far jump, the optical head is controlled to move by half the motion distance in an acceleration mode, and by the remaining half in a deceleration mode.

Title: Production method for corn with enhanced quality grain traits
Inventor: BERGQUIST RICHARD R
IPC: A01H1/02
Filed: 1991-10-11
Granted: 1999-01-05
Abstract: A novel method of producing corn grain with enhanced quality traits including high oil content has been developed. Through pollination of male-sterile hybrid corn plants by nonisogenic corn plants possessing genes which control the expression of enhanced quality grain traits, grain is obtained possessing such traits much higher than would be expected for self- or cross-pollination. This method can be practiced by farmers using currently accepted farming practices to directly obtain high yields of high-oil corn grain, high-protein corn grain, and other valuable grain for animal feed and other products.

Title: A beverage package
Inventor: FORAGE ALAN JAMES
IPC: B65D79/00
Filed: 1993-10-29
Granted: 2003-09-23
Abstract: A beverage package has a sealed can 1 having a chamber containing beer 20 having gas in solution and forming a headspace 21 containing gas at pressure greater than atmospheric. A hollow insert 6 in the chamber 5 forms a secondary chamber 10 containing gas at pressure greater than atmospheric. The insert 6 is responsive to a pressure differential developed 'when the top 4 of the can 1 is opened to inject gas under pressure into the beer 20 through an aperture 11 at the top of an extension 9 of the insert. Said injection of gas liberates gas from solution in the beer 20 and the aperture 11 is located near to the surface of the beer 20 so that, preferably, less than 300 of the volume of the beer 20 is subjected to said gas liberation and adequate gas is maintained in solution in the beer 20 to provide "sparkle" from natural liberation of gas when the beer is poured into a drinking vessel.

Title: Optical fiber splice
Inventor: LARSON DONALD K
IPC: G02B6/24
Filed: 1992-07-27
Granted: 2004-05-25
Abstract: An optical fiber splice comprising a hinged splice element having two legs, at least one of the legs having a groove therein for holding the fibers to be spliced, a base for receiving the splice element, and a cap fitting over the base which has camming bars extending into the base and around the splice element, the caming bars urging the legs into a closed, clamping state. The camming bees are shorter than the splice element, applying the clamping force only to the center thereof, which allows the legs to flex open of their ends and apply a gradual clamping to the fibers.  Alternatively, the camming bars may be thicker at their center and have inwardly facing surfaces which are convex, providing gradual clamping of the fibers which minimizes insertion losses due to microbending. The cap is provided with tabs which hold the cap in open and closed positions, the open position allowing insertion of the fibers into he splice elment, and the closed position causing the convex surfaces of the camming bars to forcibly contact the legs of the element and thereby clamp the fibers.

Title: Networked system for display of multimedia presentations
Inventor: KATSEFF HOWARD PAUL
IPC: H04N21/658
Filed: 1995-01-23
Granted: 1999-09-21
Abstract: Disclosed is a networked multimedia information system which may be utilized to record, store and distribute multimedia presentations together with any supplemental materials that may be referenced during the presentation. The recorded presentation, together with the associated supplemental materials, may be simultaneously presented on a display containing two separate viewing windows. The effects of network congestion are minimized by prefetching audio and video data for storage in audio and video buffers. An adaptive control algorithm compensates for network congestion by dynamically varying the rate at which video frames are retrieved over the network, in response to network traffic conditions. The audio playback speed is reduced if the audio data does not arrive fast enough over the network to maintain the desired size of the audio buffer after the amount of video data transmitted across the network has been reduced to a minimum value.

Abstract: A method and a packaging arrangement for packaging products, such as contact lenses, in packages such as blister pack. The arrangement has a movable support base having on its upper surface a plurality of substantially identical support pallets, spaced equally apart along the movable support base. Each of the pallets is particularly designed to support and align an array of individual package bases. The support base is sequentially moved through substantially equal incremental movements, with stops between each sequential movement, such that each support pallet with an array of individual package bases thereon is sequentially stopped at spaced stations in the packaging arrangement. At a first station, a loader loads an array of package bases in the support pallet then at the first station. At a subsequent foil placement station, a placer unit places a sheet of laminated covers over the array of package bases. At a still subsequent heat sealing station, a heated seal head heat seals the laminated covers to the package bases. At a subsequent unloading station, an unloader unloads the sealed packages from the packaging arrangement for subsequent processing.
