Title: Method of producing pockets in circumference of rings - uses superimposed rotary motions of work and single point tool to generate cycloidal tool path
Inventor: LEY HANS
IPC: F16C33/49
Filed: 1990-10-30
Abstract: The pockets are produced with a combination of rotary motions of the work and a single-point tool in a monner similar to polygon turning. The workpiece cutter rotates about the axis (13). The tool (9) rotates about a parallel axis at the end of an arm (10) which itself rotates about a parallel axis (14) in a machine slide (12); the motion of the tool is therefore cycloidal. The slide can be fed along the axis of the work and the distance e between axes (13) and (14) can be varied. The tool is fed into the ring from the inside or, depending on the required geometry, from the outside. The number of pockets machined out is a fraction of the ratio of work speed to tool speed. USE/ADVANTAGE- Bearing case prodn. Rapid machining and good surface finish. Slightly flexible.

Patent DE-4129725-A1 (DE)
Inventor: ROTH ANDREAS
IPC: A01B59/042
Filed: 1991-09-06
Abstract: The invention relates to a device for connecting an agricultural machine (2) to the tractor (1) towing it and driving it via a power take-off shaft (10). It comprises a double gear (8).

Patent DE-4132820-A1 (DE)
Title: Stacked capacitor with increased capacitance and improved lifetime - formed using dielectric composed of oxynitride, nitride and oxide with optimised thicknesses
Inventor: OHI MAKOTO
IPC: H01L27/10
Filed: 1991-10-02
Abstract: The semiconductor device features storage capacitors consisting of 2 electrodes, pref. doped polysilicon layers (111b, 113), between which a dielectric composite layer (112) is enclosed. The first part of the dielectric layer is an oxynitride layer, pref. a Si-oxynitride, the last one an oxide layer, pref. Si-oxide pref. at least 0.5 nm thick and not more than 2 nm, and enclosed between these a nitride layer, pref. a Si-nitride layer. The compsn. of the oxynitride layer is pref. SiOx/2N(4-x)/3 in which x is between 0 and 4. A process flow is also claimed. USE/ADVANTAGE - The dielectric layer has a higher effective dielectric constant, which allows a thicker layer to be used. This increases the resistance to dielectric rupture under the influence of the electrical field during operation. The first layer has a thickness which is defined by the thickness of the native oxide. Because the wafers are brought into a cold reactor which is evacuated before the temp. is raised there is no additional growth of the oxide layer before the nitridation. The last oxide layer can be controlled easily also, by cooling the wafers in an inert ambient before exposing them to air. The thickness of this oxide layer needs to be controlled because of the requirement for a minimum thickness to compensate for weaknesses in the nitride layer and the need for a max. to avoid capacitance reduction. The process is used for the mfr. the storage capacitors of large integration DRAMs.
Patent DE-4136181-A1 (DE)
IPC: H03K17/732
Filed: 1991-11-02
Abstract: In a circuit for the hard control of a GTO, the line inductor (L1) and the internal inductance of the GTO (L2) with a first capacitor (C1) connected in series via a switch (S) form a series oscillator circuit within the gate circuit. Here, the values of the first capacitor (C1) and the first inductor (L1) are selected so that, when the first capacitor is discharged via the two inductors (L1, L2), the gate current arising from the first capacitor (C1) in the first quarter-oscillation of the series oscillator circuit exceeds the 0.5 multiple of an anode current of the GTO to be switched off within less than 5  mu s. In addition, there are first means which, after the first quarter-oscillation of the series oscillator circuit, decouple the first capacitor (C1) from the generation of the gate current and cause the gate current to decay so slowly that it is at all times greater than the GTO tail current. Finally, there are second means in the form of a recharging circuit which is activated during the decay of the gate current and, after the decay of the gate current, is applied to the gate (G) of the GTO with an adequate holding voltage (VH) for blocking purposes.
