Title: Defect skipping mechanism for disk drives
Inventor: DUJARI VINEET
IPC: G11B20/18
Filed: 1988-07-05
Abstract: A novel technique for skipping defects on a magnetic or writable optical disk is described. The technique includes a sector format comprising a header (24) and data area (28), wherein the data area can include one or more "bad areas" (108, 116) which will be skipped when data is being written to or read from the sector. The bad areas are variable in size and may be located anywhere in the data area, including in an EDAC. The header includes a defect descriptor (48) comprising a defect pointer (70, 72) for each of the bad areas supported. Each defect pointer contains a value (74, 78) indicating the number of bytes in the good data area (106, 114) preceding the bad area pointed to by the defect pointer, and a value (76, 80) indicating the number of bytes in the bad area. The value indicating the number of bytes in a good area is set to a value indicating a number of bytes as least as large as the sector size if there is no subsequent bad area in the data area. A method for reading or writing data to a sector formatted as above is also described. A method for formatting a disk as above is described as well.

Title: Verfahren und Vorrichtung zur Herstellung eines stranggepressten, verstreckten, nahtlosen Schlauches
Inventor: STRUTZEL HANS
IPC: B29C48/90
Filed: 1988-08-24
Abstract: Ein aus einer Strangpresse über eine Ringdüse (5) extrudierter, nahtloser Vorschlauch (3) durchläuft einen Kalibrator (7) und umgibt koaxial ein Sondenrohr (12), das durch die Ringdüse (5) hindurch bis über den Kalibrator (7) hinweggeführt ist. Auf dem Sondenrohr (12) sitzt ein Dichtungselement (20) auf. Vor dem Dichtungselement herrscht im Rohrinneren ein Druck gleich dem Atmosphärendruck und hinter dem Dichtungselement ein höherer Druck als der Atmosphärendruck. Die Druckbeaufschlagung wird dadurch erreicht, daß ein zweiter Bandabzug (26) das Rohr (24) zusammenfaltet, so daß die durch das Sondenrohr (12) eingespeiste Druckluft den höheren Rohrinnendruck bewirkt, da das Dichtungselement (20) dichtend gegen die Innenseite des Rohres (24) anliegt. Dadurch wird eine weitgehende Drucktrennung an der Stelle des Dichtungselements (20) bewirkt. In einer ersten Heizkammer (25) wird das Rohr (24) auf die Strecktemperatur erwärmt und durch einen zweiten Bandabzug (26) mit erhöhter Streckgeschwindigkeit gegenüber der Abzugsgeschwindigkeit des ersten Bandabzugs zu einer zweiten Heizkammer (27) transportiert, in der eine Wärmefixierung des Rohres erfolgt. Aus der Heizkammer (27) wird der Rohrschlauch mit gleicher, größerer oder kleinerer Geschwindigkeit als der Streckgeschwindigkeit durch einen dritten Bandabzug (28) weitertransportiert und über eine Umlenkrolle (29) auf eine Aufwickelrolle (30) aufgewickelt.

Abstract: A field effect transistor has its drain and source regions connected between one of the two supply pads of an operative integrated circuit, the gate of the field effect transistor being connected to the other pad such that the gate is negatively biased during reverse battery to prevent current flow through the circuit in this condition and, hence, to prevent destruction of the circuit. The FET is sized to have minimal voltage drop during normal, forward battery operation of the circuit. The FET can be implemented as either an N-­channel or a P-channel device.

Abstract: A paging system allows an on-board radio unit (14) of a vehicle telephone for business use to serve as a repeater as needed. An on-board repeater (16) is mounted on the same vehicle as the on-­board radio unit (14) while a portable unit (18) is removably mounted on the repeater. When the portable unit is removed from the on-­board repeater, the on-board radio unit functions as a repeater. Even when a person who uses the vehicle on which the telephone is mounted is away from the vehicle with the portable unit, a desired voice message can be transferred to the person immediately.

Abstract: An improved boiling water reactor emergency coolant injection system network uses condensate pumps (18) in the feedwater train to function in alternate duty as short-term low-pressure coolant injection pumps. These low-pressure pumps use a reliable power supply consist­ing of the addition of one or more auxiliary generators (34), of small size and generating capacity relative to the size of the power station's main generator, which are direct-coupled mechanically to the shaft (32) of the main turbine-generator (30) and which use the spindown energy of the main turbine-generator to power the low-pressure coolant injection pumps.

Abstract: In an image forming apparatus according to an embodiment of the present invention, a fixing unit (16) demountably installed on a first frame (39) is provided with a heat roller (101), a pressure roller (102), and a lever (102a) which is pushed by a second frame ( 41) when the second frame is engaged with the first frame. The arrangement is such that the other side of the lever then pushes the pressure roller (102) at both ends of its shaft (102f) transversely towards the heat roller (101) for compression and heating of a sheet having a toner image thereon. When the second frame (41) is disengaged from the first frame (39) the pressure onto the lever (102a) is released and, consequently, the pressure roller (102) moves away from the heat roller (101) so that the pressure on the sheet is released for easy removal of the sheet therefrom.

Abstract: A print medium sheet feeding system for an ink jet prin­ter having a print head with a planar array of jets is provided by clamping the leading edge of a paper sheet after it is passed through a printing zone to a rotating assembly of parallel disks. The sheet is pulled through the printing zone by rotating a plurality of disks (14) with a clamp (50) being carried with the rotating drum (14c) formed by said disks (14). A platen (92) is pro­vided which has a flat surface in the printing zone (56) forming a tangent to the outer surface of the rotating disks (14). The sheet is initially clamped against the drum (14c) by the combination of a lever arm (80) which is selectively engageable with the drum for rotation therewith and an attached actuating arm (72) having a plate (52) which secures a sheet to the drum surface. The resulting clamp (50) rotates with the drum (14c) until the sheet passes below idler rollers which are biased against the drum surface. These rollers then hold the sheet against the drum for motion of the sheet with the drum surface. The actuating arm is released from the drum after a sheer passes below the rollers, thereby allowing any sized sheet to be fed through the system.

Abstract: A method is disclosed of forming a helical spring composed of a plurality of parallel, coiled strands of spring wire (31) with such strands being unconnected along a major part of their length but being joined together at least at one end of the spring (32). In a preferred embodiment, such strands or wires are welded together at opposite ends of the spring. Such a spring is formed by incrementally advancing a plurality of wires (W1, W2, ---) in contiguous, parallel realtion towards a wire-coiling station (11,12,13) and then, at the termination of a coiling step, interrupting such advancement to sever the wires through, or immediately adjacent to, a welded zone (44) while at the same time welding such wires together in a further zone (48) spaced a precise distance from the point of the severing operation. The invention extends to helical torsion springs (30,30′) produced by the above method.
