Patent EP-0298237-A2 (EP)
Inventor: SPIES HANS
IPC: G08B13/18
Filed: 1988-05-25
Abstract: The invention relates to a laser diode (1), consisting of a semiconductor material, which has reflecting surfaces (3, 4) on both sides of a resonant cavity (2), to produce laser resonance, the one surface being designed as a partially light-permeable outlet window. In order to increase the light yield of such a laser diode and to be able to use it for widespread applications, according to the invention it is proposed that the two surfaces (3, 4) are of approximately equal light permeability, preferably having a transmission level of in each case 50%. In comparison with a conventional laser diode, with a total reflecting surface and a partially permeable mirror, the light yield is increased by 40 to 60%. <IMAGE>

Abstract: In a wavelength multiplexed optical transmission system, digital signals of separate channels are respectively converted into optical signals of different wavelengths which are assigned to plural optical channels and multiplexed into a single optical signal for coupling to an optical transmission medium. Each of the optical channels includes a semiconductor laser for emitting a laser beam and an optical phase or frequency modulator for modulating the laser beam with one of the digital input signals. A light intensity limiter is located in the path of the light from the modulator to maintain the modulated laser beam at a constant intensity to prevent interchannel crosstalk which would otherwise occur as a result of variations in the output of the laser and/or modulator. Alternatively, a laser diode saturable light amplifier is located in the output path of the modulator to maintain the modulated light intensity constant.

Abstract: An ion beam (109) is fired in the direction of a magnetic field (B) into an ion trap to introduce ions into the ion trap (110) of an ion cyclotron resonance spectrometer, which trap is arranged in the constant, homogeneous magnetic field (B). In this case, the speed of the ions entering the ion trap through a hole (115), which is located in a wall (111) of the ion trap, is reduced, as a result of which they remain for a longer period  in the ion trap. The invention is intended to improve the accumulation of ions which is possible in this way in the ion trap, particularly in the case of weak ion flows. 
<??>According to the invention, the reduction in the speed of the ions in the axial direction of the ion trap is carried out by a movement component aligned at right angles to the magnetic field (B) being imparted to the ions which have penetrated into the ion trap (110). For this purpose, an electrical field can be generated in the vicinity of the hole with the aid of electrodes (121, 122) arranged on both sides of the hole (115) through which the ions enter into the ion trap (110), as a result of which electrical field a transverse movement component is imparted to the ions which pass between the electrodes. In this way, the ions are deflected onto a path which greatly increases the time during which the ions remain in the ion trap.

Abstract: A driver for an electro-optical transducer, such as a light-emitting diode (LED) (35) is disclosed which shapes current pulses so as to contain "spikes" during turn-on and turn-off in order to quickly charge and discharge the junction and stray capacitances of the LED. Degeneration resistors (39,41; 47,53) interconnect the emitters of switching transistors (38,40; 46,52) used in a differential amplifier (32) supplying the current to the LED and in a differential amplifier (34) supplying a "peaking" current to the switching amplifier. A capacitor (44) couples the amplifiers to conduct the additional current to the LED when it is initially turned on and charges the cathode of the LED. The emitter degeneration resistors couple the amplifiers (32,34) to current sources and allow the amplifiers to be driven by emitter-coupled logic (ECL) gates without ringing. The resistors also linearize the transfer functions of the amplifiers so that the voltage swing of the ECL driver does not overly turn-off the transistors within the amplifiers, thereby improving response time.

Abstract: A computer system is presented. The computer system has a host computer (20), one or more personal computers (10) and a data transport system (30,31) which transports data between the host computer (20) and the personal computers (10). 
     On each personal computer (10) resides a number of applications (11). Each application (11) may utilize the resources on the host computer (20) by use of a requester program (13,15) existing on the personal computer (10) and a host server (24) residing on the host computer (20). When the application (11) desires a command to be processed by the host server (24), the application (11) transfers the command to the requester program (13,15). The requester program (13,15) receives the command and any parameters or other data associated therewith. The requester program (13,15) translates or reformats the command and associated information in preparation for sending the command et al. to the host computer (20). 
     The requester program (13,15) hands the translated command to data transport software (17,18). The data transport software (17,18) serves to interface the requester program (13, 15) with the data transport system (30,31) and serves to interface the host server (24) with the transport system (30,31). The translated command is thereby transferred from the requester program (13,15) to the host server (24).   
     The host server (24) oversees the execution of the command. The host server (24) may call data base intrinsics (22), operating system intrinsics (21) or remote procedure intrinsics (23) to execute the command. 
     When the host server (24) is started in response to a request originated by an application (11), host server (24) allocates a certain amount of memory on the host computer (20) for use by the application (11) as a scratch pad. Through the use of remote procedures (23) the application (11) may store information to the scratch pad, modify data in the scratch pad and retrieve data from the scratch pad.
