Patent DE-19933087-A1 (DE)
Title: Controlling motor vehicle drive unit involves limiting magnitude of reduced torque, which is reduced when tendency to spin occurs on drive wheel, to driving situation-dependent minimum
Inventor: HESSMERT ULRICH
IPC: B60T8/1763
Filed: 1999-07-15
Abstract: The method involves limiting the magnitude of the reduced torque, which is reduced when a tendency to spin occurs on at least one drive wheel of the vehicle, to a minimum.

Patent DE-19936290-A1 (DE)
Title: Heavy work motor vehicle has connecting arrangement that automatically switches drive coupling, gear change couplings in response to change operation of first/second gear change unit
Inventor: ASADA AKIHIRO
IPC: F16H61/00
Filed: 1999-08-02
Abstract: The vehicle has an engine (8), a drive coupling, a first gear change unit with a number of gear ratios and a number of gear change couplings switchable in the idle state, a second gear change unit driven by the first and switchable between a transmission position and an idle position and a drive arrangement driven by an output of the second unit. A connecting arrangement automatically switches the drive coupling and gear change couplings in response to a change operation of the first or second unit so that when a unit is switched the coupling is decoupled and the other unit changed to idle, and when a unit is changed to the transmission state the drive coupling is coupled and the other unit is restored to the transmission state. The connecting arrangement can be actuated to restore the other unit to the transmission state and then engage the drive coupling.

Title: Anordnung zur Abgasregelung
Inventor: LOESING KARL-HEINRICH
IPC: F02M26/47
Filed: 1999-11-09
Abstract: Die Erfindung betrifft eine Anordnung zur Abgasregelung. DOLLAR A Bekannte Anordnungen zur Abgasregelung insbesondere bei Dieselmotoren weisen einen Luftmassensensor (2) im Luftansaugkanal einer Brennkraftmaschine auf. Ein dabei ermitteltes Sensorsignal wird zur eigenständigen Steuerung eines Abgasrückführsystems (AGR-System) benutzt. DOLLAR A Nachteilig bei den bekannten Anordnungen ist, daß hierbei eine indirekte Messung stattfindet, wodurch die Regelung der Abgasrückführung über die angesaugte Luft, nicht aber über das Abgas selbst erfolgt. Dadurch kommt es zu ungenauen Regelmeßwerten. DOLLAR A Der Erfindung liegt die Idee zugrunde, einen Luftmassensensor (7) als Abgasmassensensor direkt in die Abgasrückführleitung (6) vor einem Abgasrückführventil (6) einzubinden, um so eine direkte Messung und Regelung des Abgases vornehmen zu können. Dazu wird vor dem Abgasmassensensor (7) eine Abgaskühlung (8) eingebaut, die die Abgasleitung (6) und damit die Abgase abkühlen. Der Abgasmassensensor (7) ist zudem gegen Hitze und Schmutz resistent.

Abstract: A ROM constituting a variable length coding
table of 2 picture element range is provided. A motion
vector within the range of 2 picture elements is given to
the ROM to provide a VLC code corresponding to the motion
vector within the range of 2 picture elements. In a
calculation circuit, assuming that the value of a motion
vector within the range of 4 picture elements is X, a
quotient Y and a remainder Z are obtained by the division
of X by 2. The quotient Y is supplied to the ROM whose
output is added the remainder Z at an additional circuit
to obtain a VLC code corresponding to the motion vector
lying within the range of 4 picture elements. This is
equivalent to the coding at the variable length coding for
four-picture element range. By sending a flag indicating
whether a motion vector range is 2 picture elements or 4
picture elements, the motion vector is correctly
reproduced from the VLC code. By the use of the single
table ROM, a motion vector within the range of 2 picture
elements and 4 picture elements can be coded to reduce the
load imposed on the hardware.

Abstract: A disk apparatus includes a DSP core. If given an instruction to skip music during
reproducing with an MO disk, the DSP core sets to a counter a count value corresponding
to the number of tracks to jump over. Then, tracking servo is turned off and an optical
pickup is moved in a radial direction of the MO disk. The DSP core detects rising and
trailing edges in a TZC signal and counts down the counter. When the count value
becomes 1, a level of the TZC signal is determined to judge whether there is variation in
offset value or not, If there is variation in offset value, edges are considered counted
incorrect. Accordingly, the count value is incremented. Thus, jump can be made to a
desired land or groove, i.e. access can be made positively to a target position.

substrate and having a first trench (28) therein, and a first
metal plug (30) extending upwardly from the substrate into the first
trench. An interconnection line (32) overlies the first trench and
contacts the first metal plug to define anchoring
recesses (34) on opposite lateral sides of the first metal plug. A
second dielectric layer (36) is on the interconnection line
and has a second trench (38) therein. A second metal plug (22)

anchor portions (42) connected to the body portion and
engaging the anchoring recesses to anchor the second
metal plug to the interconnection line. The capacitor stack (44,48,46)
overlies the second trench and contacts the second metal plug.
Because the second metal plug is anchored, a depth of the second
trench can be greater, thereby increasing the surface area of the
capacitor, without the metal plug becoming loose and separating from
the underlying interconnection line.
