Title: Sense amplifier
Inventor: PROEBSTING ROBERT J
IPC: H03F3/45
Filed: 1995-10-02
Abstract: An amplifier comprises first and second input transistors 14, 22 and cross coupled third and fourth output transistors 54, 70 wherein the first and second transistors have greater current capacity than the third and fourth transistors. Transistors 54 and 70 are two thirds the width of transistors 14 and 22. A first amplifier stage 14, 22, 54, 70 is biased to minimize current consumption of all stages of the amplifier and to provide outputs of the first stage that are high enough in voltage to allow proper operation of a second stage 100, 104, 108, 112 of the amplifier, yet low enough in voltage to allow a current mirror to be integrated into the second stage of the amplifier. The integration of the current mirror into the second stage amplifier reduces capacitive loading on the outputs of the second stage increasing speed while eliminating the extra power normally associated with a separate current mirror. An alternative differential output circuit (Fig. 2) may be used coupled to outputs 128 and 144. The sense amplifier may be used with a static or dynamic RAM. <IMAGE>

Title: Variable timing i.c. engine valve actuating arrangement eg for internal EGR
Inventor: PIRAULT JEAN-PIERRE
IPC: F01L13/00
Filed: 1997-07-30
Abstract: At least one cam 4 of a camshaft 3 is engaged by a face 5b of a tappet 5 which is mounted slidably and rotatably in a tappet holder 8. The tappet holder 8 is mounted in a bore 22 in the engine structure so as to be rotatable about an axis of rotation which is inclined to a normal to the cam-engaging face 5b of the tappet 5. Tappet holder 8 carries a pinion or gear segment 11 which is engaged eg by a linear rack 12 driven by a hydraulic or solenoid actuator in response to sensed engine speed and throttle position. To enable EGR, the tappet holder 8 is rotated through about 180 degrees from a neutral position A to an operating position B (broken lines in fig.2). The point of contact of the tappet 5 thus moves around the cam 4. For, example, a rotation of 7.5 degrees of the tappet holder 8 can produce a timing retard of 30 degrees of the exhaust valve to induce sufficient internal EGR. With internal EGR, the expansion stroke is increased, and HC and NOx emissions are reduced compared to external EGR.
