A system and method for providing dynamically variable maps in a video game is disclosed. A map is provided that defines a playable space available to one or more game players in a video game. Gameplay is monitored in real-time for the detection of a trigger event. Upon detection of a trigger event, a map management engine dynamically modifies a configuration of the map to improve the gameplay experience based on the type of trigger event. Dynamic modification of a map may comprise altering one or more of the map boundary, and / or the location, position, size, number, state, etc. of one or more static map objects or dynamic map objects. As a result of the dynamic modification of the map, the map may transform from its initial (or first or beginning) configuration to a modified (or new or second) configuration.

The drive mechanism has a differential spindle (13) which converts a rotation of a graduated disk (26) into a displacement of the tool carrier (10) for the fine setting of the boring diameter. The differential spindle (13) is mounted in a bore (51) of the tool carrier (10) and extends at right angles to the rotation axis (A).

In a shock-secure door or hatch arrangement on marine ships, a doorway frame, on two opposite longitudinal edges thereof, has continuous latching bars that are receivable in corresponding grooves in opposite edges of a door in order to latch the door in a closed position. The latching bar on the hinged edge of the doorway frame is stationary and engages into the associated door edge groove during a closing motion of the door. The latching bar on the opposite edge of the doorway frame is movable by actuating elements so as to engage into the respective associated door edge groove for latching the door in its closed position. A locking mechanism locks and unlocks the movable latching bar in its latched position.

PCT No. PCT / DE98 / 00217 Sec. 371 Date Dec. 4, 1998 Sec. 102(e) Date Dec. 4, 1998 PCT Filed Jan. 24, 1998 PCT Pub. No. WO98 / 45592 PCT Pub. Date Oct. 15, 1998A fuel injection pump for internal combustion engines, is proposed, with a distributor pump piston (6), which is supported in a housing bore (5) and on its jacket face, has a distributor groove (12), a filling groove (18), which is connected to a pressure relief chamber, and a pressure compensation surface (36). This filling groove constitutes a first leakage route (39) in the direction of the distributor groove (12) and constitutes a second leakage route (42) in the direction of an annular groove (20) in such a way that the pressure compensation surface, which is otherwise always closed by the inner wall of the bore (5), produces a high-pressure fuel supply by way of the first leakage route (39) in the direction of the pressure compensation surface (36) and this pressure compensation surface (36) is in turn relieved by way of the second leakage route (42) in the direction of the annular groove (20). The disposition of the pressure compensation surface (36) diametrically opposite the distributor groove (12) results in a very favorable compensation of the forces acting on the distributor pump piston during the high-pressure delivery phase, wherein by way of the pressure supply by means of the leakage routes mentioned, these compensating forces can be brought into line with the respective pressure level and the loading of the distributor pump piston (FIG. 4).

To realize an air guide of a radio-frequency heating apparatus that enables fixing of a lamp without use of a vis though it is made of a metal plate material. An air guide 9 made of a metal plate material is formed with two inverted-L-shaped nails 15. A holding portion 13 of a lamp 12 is hooked on the nails 15 and a waveguide holding plate 19 is brought into contact with an opposed surface of the holding portion 13 of the lamp 12. As a result, the lamp 12 can be fixed without using a vis and hence a step of fixing the lamp 12 with a vis can be eliminated. An inexpensive configuration can be realized that is free of fear that a disconnection may occur in a filament due to vibration.
