Patent EP-0335691-A1 (EP)
Inventor: CAMERON KEITH HENDERSON
IPC: H01S5/00
Filed: 1989-03-29
Abstract: An external cavity laser assembly in which the laser chip is within a hermetically sealed package and the external cavity is outside the hermetic package. A collimating lens in a screw threaded mounting is disposed outside the hermetic package, the screw thread permitting focussing. The cavity is tuned by rotation and translation of a grating, the position of which is electrically controlled via piezoelectric stacks. Thermal expansion of the stacks is compensated by mounting the grating on a rod of suitable material (e.g. ceramic) which also serves to reduce the cavity length whilst allowing maximum piezoextension. In a second embodiment the assembly is a tunable laser amplifier, with a grating being driven in a similar manner to provide the tuning.

Abstract: The accumulator fuel injection system (10) has a leak passage (16,37) formed in an accumulator (5) in which a fuel supply pressure from a fuel injection pump is temporarily stored, and a control valve (34) adapted to be opened and closed by the energization of a solenoid (35) so as to open and close this leak passage. In order to secure a predetermined fuel injection quantity, the pressure in the accumulator (5) is reduced suddenly by an operation of the control valve (34) to a level not higher than a needle valve closing pressure to shorten the fuel injection time and increase the pressure in the accumulator (5) to a high level, whereby a fuel injection rate is increased. A pressure chamber (40) having a relief valve (41) therein is further provided in the portion of the leak passage (37) which is on the downstream side of the control valve (34). Therefore, even when an ignition delay is shortened in a high-temperature condition of a heat insulating engine, the quantity of the fuel to be injected into a combustion chamber is maintained constantly at a predetermined level, and the performance of the engine is improved. Moreover, the pressure chamber prevents a leak pressure from decreasing to a level not higher than a predetermined level, so that a wasteful operation can be minimized during the increasing of the pressure in the accumulator (5) while a subsequent fuel injecting step is carried out.

Abstract: A switching device emits signals for direction indication, switching over from dipped headlights to full beam, the headlight flasher and the horn of a motor vehicle. For triggering the signals, it has a manually actuatable switching lever (10, 12) which is mounted so as to be rotatable and tiltable in a switching console (14). A tension spring (26), one end of which engages directly or indirectly on the switching lever (10, 12) and the other end of which engages directly or indirectly on the switching console (14), extends in the switching lever axis (28). The tension spring (26) is hooked into a pin (34), which is connected to the switching lever (10, 12) and at the same time fulfils the function of a tilt axis, and of a rotary stop and ensures a minimum spacing between switching lever (10, 12) and switching console (14). The horn function is implemented by means of a push-rod (162) which is mounted in the switching lever (10, 12) and on which a switching piece (178) of a switching element is mounted. The flashing function is carried out by means of two microswitches (20, 24) mounted off-centre on the switching console (14), it being possible to actuate said microswitches by rotating the switching lever (10, 12) and overcoming catch positions. The switching over between dipped headlights and full beam occurs by tilting the switching lever (10, 12) between catch positions (61) of a switching link (18) in which the central microswitch (22) is actuated in all switching positions by means of a component (130) which engages through the switching console (14). The headlight flasher facility is triggered by contact pieces (182, 184) which are mounted at the lower end (148) of the switching lever (10, 12) or on the switching link (18) and can be brought into contact by tilting the switching lever (10, 12) into a key position defined by the switching link (18). <IMAGE>
