Patent DE-19631911-A1 (DE)
Title: Charge feedback differential logic circuit, e.g. for VLSI technology and multimedia system
Inventor: KONG BAI SUN
IPC: G06F7/507
Filed: 1996-08-07
Abstract: The differential logic circuit has a charge recycling differential logic (CRDL), a structure which has a logic network (10) with complementary transistors as well as a load circuit and an acceleration buffer (14). The load circuit has a pair of cross coupled PMOS transistors (MP1,MP2), output nodes and an NMOS transistor (MN1) coupled to the gates of the transistors. The control variables are coupled to an NMOS pass transistor logic network (16). The circuit receives pulse signals of two voltage levels at two nodes (/OUT,OUT). The PMOS transistors of the load circuit increase the voltage at the first node to a first value Vdd, when the pulsed signal changes from a first to a second level. The network drops then the voltage at the second node to a second value. If the pulsed signal changes from a second level to a first, the NMOS transistor applies to both nodes an intermediate voltage.

Title: Internal combustion engine
Inventor: CLARK CHRISTOPHER
IPC: F02B41/00
Filed: 1996-12-18
Abstract: The engine has at least one cylinder chamber (2) with a combustion chamber (13) and a piston (3) which reciprocates between a bottom dead center and a top dead center to vary the cylinder volume.

Patent DE-19729960-A1 (DE)
Title: Method of detecting impacts
Inventor: SPIES HANS
IPC: B60R21/01
Filed: 1997-07-12
Abstract: The method involves measuring the acceleration acting on a vehicle using an acceleration sensor (2.1,2.2). The acceleration signal, or preferably its integral is compared with a variable triggering threshold. At least one pre-crash sensor (1.1,1.2) records the variation of the relative speed or distance of objects within a defined proximity of the vehicle. If the relative speed is detected to be above a given threshold or the distance is detected to be below a given threshold, this is identified as a safety critical condition and the triggering threshold is reduced.

Title: Pressure injection molding of objects bulging selectively on extraction
Inventor: GOSDIN MICHAEL DR
IPC: B29C44/10
Filed: 1997-11-19
Abstract: Foaming agent (5) and plastic (4) are plasticized (3) to a homogenous melt (2). When injected, it completely fills the mold (7) cavity (6).

Patent DE-19805263-A1 (DE)
Inventor: KAMKALOW FRITZ S
IPC: G01M3/18
Filed: 1998-02-10
Abstract: The invention relates to a method for detecting and locating leakages by using sensor lines (5) which are insulated or arranged in an insulated manner. According to said method, the position of irregularities is determined for different parameters from the delay time and magnitude of reflected or partly reflected impulses. The delay-time images for the relevant parameters are stored or represented until a delay-time archive of as many parameters as possible is obtained. When the reflected impulse exceeds a predefined threshold in relation to previously recorded delay-time curves the corresponding area is defined as an error. New delay-time images are recorded subsequently for various parameters which as a curve are compared with the previous delay-time image of the corresponding parameter.
