Filed: 1992-04-10
Abstract: A gear pump of variable capacity and transfer rate but fixed rotational speed comprises a drive shaft 1 carrying a drive gear 3 and an axially movable idler shaft 2 carrying an idler gear 4. A housing 6 for drive gear 3 is slidable along the drive shaft 1 and coupled for rotation therewith and a housing 7 for the idler gear 4 is disposed rotatably but axially fixedly in an end cover 8. The drive gear housing 6 is held rotatably between the idler gear 4 and a securing ring 16 on the idler shaft 2, whereby the drive gear housing 6 is constrained to move axially with the idler shaft 2. Starting from a position in which the gears 3, 4 are completely engaged, the idler shaft 2 may be slid towards the idler gear housing 7. The idler gear 4 and the drive gear housing 6 move with the idler shaft 2, such that the gear 4 moves into its housing 7 and the drive gear housing 6 moves over its gear 3. In this way, the available extent of the gear 3, 4 for fluid transfer is decreased. <IMAGE>

Title: Navigation system with route determination process for a road vehicle
Inventor: INOUE NOBUTAKA
IPC: G08G1/0969
Filed: 1993-09-24
Abstract: A navigation system for a road vehicle provides a route determination process by which a route is determined intersection by intersection. When a starting point and intended driving direction are entered into M4, a road is selected by M5, determined by M11 as the route to take, and indicated as the route on a display M1. A further road, of the same category as the road first determined, is determined as a continuation of the route, using M6. Automatic route determination is thus consecutively effected from the starting point toward an intended destination. Should cancellation of the determined route be instructed using M10, the route is cancel led intersection by intersection. When the cancellation is finished or if no road can be selected, the navigation system recognises the end of the determined route as a new starting point. <IMAGE>
