Patent EP-0332301-B1 (EP)
Inventor: KUBINEC JAMES J
IPC: H03K17/16
Filed: 1989-02-16
Granted: 1993-11-18
Abstract: A circuit is provided which modifies a digital drive signal to produce a time variant drive signal for application to a gate of a bus driver transistor. The circuit's purpose is to reduce the amplitude of ringing on a bus, due to rapid discharging of current from the bus, in order to prevent unintentional triggering of devices connected to the bus. A P-channel MOS transistor (60) and N-channel MOS transistor (50) are connected so that the digital drive signal (VG) is simultaneously applied to the source of the P-channel MOS transistor (60) and to the drain of the N-channel MOS transistor (50). The gate of the driver transistor (10) is connected to the drain of the P-channel MOS transistor (60) and the source of the N-channel transistor (50). The width-to-length ratio of the channels of the P-channel (60) and N-channel MOS (50) transistors, and the gate voltages, are chosen so that application of a drive signal to the circuit causes the N-channel MOS transistor (50) to rapidly apply a limited drive signal to the gate of the driver transistor (10) and causes the P-channel MOS transistor (60) to apply a gradually increasing drive signal voltage to the gate of the driver transistor (10). By choosing the proper width-to-length ratios and gate voltages, the time variant drive signal applied to the gate of the driver transistor (10) will not produce objectionable ringing on the bus when the bus is intended to be at a low level.

Compte tenu des avantages offerts par les opérations relativement rapides d'insertion et de suppression (et, de ce fait, des opérations de tri), des archives peuvent être conservées selon un ordre classé, au moyen d'une touche dans la structure de mémoire. Le maintien, par une touche, des archives dans une liste de classement, permet d'accéder relativement rapidement aux archives correspondant à la touche, en ayant recours à une technique de recherche binaire ou analogue. Selon une forme d'exécution particulière, la mémoire associative (1) peut être mise en ÷uvre en utilisant des structures RAM (mémoire à accès sélectif) couramment disponibles. Dans des variantes d'exécution, la mémoire associative peut être mise en ÷uvre en VLSI (très haut degré d'intégration).

Abstract: In the housing of a spherical piston pump 10, shown in longitudinal section in Figure 3, a sleeve 16 with a working chamber 15 is rotatably mounted about the longitudinal axis 30 of the housing. In this working chamber 15 a swash plate 21 is supported which rests by way of a bearing journal 26 on a pivotally mounted bearing section 19. This swash plate 21 is driven by a drive shaft 25 and a partition wall 22 arranged on this, on both sides of which chambers 53 and 54 are located which interact with chambers 55 and 56 located on the other side of the swash plate 21 and are connected via ducts 51 and 52 to inlet or outlet apertures 49 and 50 located in the housing 9. Due to rotation of the sleeve 16 and the bearing section 19 the angle between the housing longitudinal axis 30 and the longitudinal axis 32 of the bearing journal 26 can be varied in such a way that the volumes of the chambers 53 to 56 and hence the quantity delivered by the spherical piston pump 10 also vary. <IMAGE>

Abstract: The method is used for operating an invertor-controlled bridge circuit for pulse-width modulation, especially for regulating a load connected in the diagonal branch of the bridge circuit via an inductive transformer. Electronic switches (transistors), controlled by the invertor, are provided in the bridge branches. These switches are opened and closed in pairs and in an alternating sequence. Of the two pairs of electronic switches (5, 6; 7, 8), which are in each case activated in pairs, the one pair (6; 8) are operated at a duty cycle of barely 50%. The other electronic switches (5; 7) are used for the pulse-width modulation. The two electronic switches (6; 8) which are operated with a duty cycle of barely 50% are connected to a single inductive transformer (14). This transformer has two secondary windings (15, 16) which are arranged in a balanced manner and are connected in opposite polarity. One of the two electronic switches (6; 8) which is operated with a duty cycle of barely 50% is connected to each of the two secondary windings. <IMAGE>

Abstract: To reduce shift bump and increase smoothness during upshifts, pressure into an on-coming clutch of an automatic transmission is electronically controlled using a turbine speed adaptive strategy. Because of the change in engine speed that accompanies this torque flow path transition, such upshifts include a torque phase and an inertia phase. To make the shift smooth, the torque phase is completed quickly by boosting pressure at the beginning of the upshift. Just before the torque phase is completed, the pressure is lowered so the inertia phase bump is reduced. The end of the torque phase is predicted by monitoring the turbine speed rise since the start of the shift and comparing it with a value which is derived from an adaptive table. During the inertia phase, the pressure is ramped up to complete the shift quickly and smoothly. Ignition spark timing is reduced in the inertia phase to further improve shift feel.   <IMAGE>
