Patent DE-3737451-A1 (DE)
Title: Electrical fuse link
Inventor: HARBAUER PETER
IPC: H01H85/08
Filed: 1987-11-04
Abstract: The fusing conductor is intended to be usable with a high continuous current load capacity and a short response time in the event of overcurrent. Two or more unweakened sections having a predominantly uniform thickness are fitted at a distance apart from one another on a carrier (2) having good thermal conductivity, preferably ceramic. The intended melting point of the fusing conductor consists of a relatively thin fusing conductor which is fitted onto the unweakened sections, for example by soldering or welding, runs at a distance from the support (2) in the region of the link, and can have weakened points (7) in order to increase the current intensity. The fusing conductor can be used especially for fuses having a high continuous current load. <IMAGE>

Title: Ink-ribbon cartridge with reloadable ink-ribbon spools
Inventor: SCHROEDER GUENTHER
IPC: B41J32/00
Filed: 1987-12-14
Abstract: Ink-ribbon cartridges for typewriters or office machines of similar design are subject to different construction requirements, in which case they are to be easily exchangeable above all by means of one-handed operation. Since the transporting elements, for example for the carbon ribbon, of such cartridges are also mounted in the housing, these cartridges are very expensive. In order to avoid this, ink-ribbon cartridges with exchangeable ink-ribbon spools have been disclosed. However, these have the disadvantage that deposits from the ink ribbon occur in the outlet opening (27) and the inlet opening (28) when several newly inserted ink-ribbon spools have run through. These deposits lead, on the one hand, to severe soiling of the machinery and, on the other hand, to interferences in the ink-ribbon drive. According to the invention, this is avoided in that the inlet opening (28) and the outlet opening (27) for the ink ribbon (9) in the cartridge housing have reduced-friction deflection elements with integrated dust chambers (60) and strips. These deflection elements can consist of a PTFE coating (17, 18), deflection rollers or even of special slide pieces with incorporated lubricants. By means of their outer shape, the friction-reduced deflection elements prevent soiling of the machinery and guarantee an interference-free drive of the ink ribbon. <IMAGE>

Title: Process for producing semiconductor components
Inventor: DEPPE JOHANNES
IPC: H01L21/00
Filed: 1987-12-18
Abstract: With a process for producing known semiconductor elements with a defined and passivated edge profile from a semiconductor wafer in mass production, only semiconductor elements with a simple bevelling of the lateral surface, i.e. with a so-called positive angle, for rectifier diodes of high-blocking capability can be achieved. The process according to the invention makes it possible to produce semiconductor elements with a layer sequence comprising at least three zones of alternatingly opposed types of conduction with a defined and passivated edge profile and with double bevelling of the lateral surface in the sense of a double positive angle. The process includes the following steps: Dividing a semiconductor wafer into semiconductor elements, stacking semiconductor elements and etching-resistant intermediate wafers alternately in a device, fixing the stack in a clamping device suitable for machining around its entire circumference, forming a depression on the circumference of the lateral surface of all the semiconductor elements by etching, filling the depressions with a passivating coating and separating the semiconductor elements out of the clamping device. Use of the process for producing controllable semiconductor power components.

Title: Model aircraft with a nose cone
IPC: A63H17/00
Filed: 1987-11-05
Abstract: The invention relates to a model aircraft, in the case of which major aircraft components such as a nose cone 7 are provided on a fuselage 1, in the case of which the fuselage 1 forms a fuselage upper part 2 and a fuselage lower part 4 when it is divided horizontally, and in the case of which the fuselage upper part 2, the fuselage lower part 4 and at least one of the major aircraft components 7 are connected to one another by means of plugging, clamping, latching and snapping in and/or screwing. In this case, it is desired to be able to produce the model aircraft more realistically using simplified means, such that errors (defects) can be corrected at a reduced cost. This is achieved by the fuselage upper part 2, the fuselage lower part 4 and the nose cone 7 consisting of differently coloured plastics, by the fuselage upper part 2 and the fuselage lower part 4 being connected to one another by means of at least two screws 23, and by the nose cone 7 being provided with a stud 42 which is pushed into a cutout in the fuselage lower part 4 and engages by means of a latching tab behind an opposing bearing on the fuselage lower part. The special colouring of the nose cone is achieved by producing a special nose cone part which is inserted during assembly of the fuselage or is snapped into the assembled fuselage. <IMAGE>

Filed: 1988-03-11
Abstract: A computer system and method for operating a computer system capable of running in mutually incompatible real and protected addressing modes, in which programs written for one mode can be run in the other mode without modification. The BIOS assembles two different common data areas for the two modes, each inclusive of device block pointers, function transfer table pointers, data pointers, and function pointers. The common data area for the real mode is assembled first. To assemble the pointers for the protected mode common data area, the offset values from the real mode area are copied directly, and then selector values are inserted whose physical addresses correspond to the segments of the corresponding pointers in the real mode area. The selector values are derived from a segment descriptor table.
Patent DE-3811597-A1 (DE)
Inventor: GERLACH JOHANN VON DIPL ING
IPC: F42B14/06
Filed: 1988-04-07
Abstract: The sabot (3) conventionally composed of three segments and intended for a subcalibre projectile (1) is so designed that the surface (5), on which propellent-charge gases act, is preferably drawn out frustoconically, with the apex rearwards, as far as the end of the subcalibre projectile (1). The force can thereby be transmitted in a uniform distribution virtually over the entire surface of the subcalibre projectile. At the same time, the transmission between the sabot (3) and the subcalibre projectile (1) is increased so that the entire sabot (3) can be produced from fibre-reinforced plastic, that additional positive transitions between the sabot (3) and the subcalibre projectile do not necessarily have to be present, but nevertheless a very high propellent-gas pressure (p) can be used. Preferably, each segment possesses wedge-like cavities (14) which are open in the firing direction and which are filled with cores (16, 17, 18). Plate-like parts (20) between the segments (19) are also advantageous.

Title: Device for measuring the relaxation oscillation frequency of a semiconductor laser
Inventor: IDLER WILFRIED
IPC: H01S5/00
Filed: 1989-03-30
Abstract: Even though it is possible with known measuring devices to determine the relaxation oscillation frequency of a semiconductor laser, with increasing light power the attenuation of the oscillation itself increases as well as the frequency. The resonance peak of the relocation frequency therefore quickly disappears in the signal noise, so that the intrinsic high-frequency limit can no longer be ascertained at high output powers of the laser. The technical problem to be solved consists in producing a device with which the relaxation frequency of a semiconductor laser, which is actually a determining factor for its maximum achievable high-frequency bandwidth, can be measured even in the range of several Gigahertz. This object is achieved by means of a device which is provided with an arrangement (3) which produces an optical feedback of from -50 to -20 dB to the semiconductor laser (1) and therefore reduces the attenuation of the relaxation oscillation. For this purpose, use is made of a variable reflector (3) which terminates the optical transmission path (2). The optical transmission path (2) is connected to an additional optical fibre (6) by a single-mode 3dB fibre coupler (5). A Fabry-Perot interferometer (15) with monochromator (16) connected downstream or alternatively a wideband optical sampling head (10) having a spectrum analyser (11) connected downstream is connected to the reception side of said optical fibre (6). <IMAGE>
