IPC: G11B15/473
Filed: 1984-09-13
Abstract: The rotor of an electronically commutated DC machine, which can be operated as a motor or as a generator, has at least one permanent magnet having at least four poles which are arranged concentrically with respect to the rotor rotation axis, are polarised essentially at right angles to the rotor rotation axis and are arranged adjacent to an annular magnetic return path part. The stator winding is accommodated in the annular gap between the rotor and the magnetic return path part and has a meandering conductor-track arrangement which is constructed as a printed circuit and whose straight meander sections running to and fro consist of a number of parallel conductor sections. A device which detects the angular position of the rotor with respect to the straight meander sections running to and fro supplies signals to a drive electronics device which, for its part, controls the current flow through the conductor-track arrangement such that, in consequence, said arrangement produces a magnetic field which drives the rotor. The starts and ends of the conductors forming the conductor sections are - depending on the application - connected in parallel or in series, and the geometrical arrangement of the connecting contacts of these conductors and/or of the sensors of the detection device allows direct connection to the drive electronics device. The drive electronics device is accommodated on a - preferably annular - board, around the rotor rotation axis, within the conductor-track arrangement. A DC motor which is constructed in such a manner, is electronically commutated, and has ... Original abstract incomplete.

Title: Circuit arrangement for activating piezoelectric drive elements of an ink jet printer
Inventor: ZWEIGLER WOLFGANG
IPC: B41J2/045
Filed: 1985-03-11
Abstract: The invention relates to a circuit arrangement for activating piezoelectric drive elements of an ink jet printer operating with demand-oriented droplet ejection, the aim of which it is to ensure a voltage supply which is largely independent of the load and is temperature-controlled, with optimisation of the space and power consumption. It is based on the object of developing a circuit arrangement in which the electric pulses, having a defined pulse shape, are adapted to the operating temperature and the type-related piezoelectric force and thus provide for individual calibration of the piezoelectric elements without changing their falling edge. According to the invention, the circuit arrangement for this purpose consists of a temperature correction stage connected to a number of activating stages corresponding to the existing piezoelectric elements, which correction stage is provided with a bridge circuit exhibiting a temperature sensor, which, via a two-terminal constant-voltage network, controls a series transistor linked to the activating stages and corrects the operating voltage of the piezoelectric elements in accordance with the resistance value of the temperature sensor or the temperature characteristic of a network comprising the temperature sensor. The invention finds its most appropriate application in the non-mechanical typing and printing technology, particularly in ink-jet printing technology. <IMAGE>

Patent DE-3522364-A1 (DE)
Title: Speech recognition system
Inventor: SAWAI HIDEFUMI
IPC: G10L15/00
Filed: 1985-06-22
Abstract: In a speech recognition system, a vector quantisation method is used so that each frame of a time-frequency distribution produced by a filter bank from speech frequency analysis is converted into a vector-quantised code with reference to a previously created code book containing a set of phonemes of very specific speech. A distribution pattern for the frequency of each of the codes in the code book is created from these vector-quantised codes. A distribution pattern of this type is stored as reference data in a memory for a desired number of speech types when the system is operated in the registration mode. When the system is operated in a recognition mode, unknown speech is subjected to a frequency analysis and vector quantisation steps in order to create an unknown distribution pattern which is then compared with each of the reference data in order to identify the pattern to which this unknown speech corresponds.

Patent DE-3526806-A1 (DE)
Title: Permanent-magnet motor
Inventor: DELECATE HEIKO
IPC: H02K53/00
Filed: 1985-07-26
Abstract: The permanent-magnet motor is used for producing mechanical energy which can be extracted on one or two shafts. It is constructed structurally such that it consists of a plurality of rotor discs and stator discs which are arranged one behind the other in the axial direction and are therefore necessary in order to make possible "true rotation" of the rotor. The rotor discs and stator discs carry permanent magnets which interact in a magnetically repelling manner, separated by one or more air gaps, characterised precisely in that, for example, the north poles of the rotor magnets rotate past one another with the north poles of the stator magnets. Power control and braking are carried out either by moving screening tubes into the air gaps or even by moving the rotor in the axial direction, or with the aid of braking magnets. Staggering of the rotor magnets and stator magnets in the radial direction is also provided in order to achieve a greater rotor torque. The same effect is also achieved by multiple arrangement of the rotor discs and stator discs in the axial direction. The motor can be designed for clockwise and anti-clockwise running, - without an external energy supply. <IMAGE>

Title: Pressure-cylinder system for admission of pressure medium to the piston on both sides, with a damping device for external, preferably vibration-like disturbance forces of high frequency
Inventor: WANKE WILHELM DIPL ING
IPC: F15B15/14
Filed: 1985-08-29
Abstract: A pressure cylinder system for producing or supporting external forces consists of the main parts: housing 1, piston 2 and piston rod 3. Pressure medium passes through inflow bores 1.3 and 1.4 into the interior of the housing 1, acts on the piston 2 on both sides with differential pressure and thereby produces an external force. In the case of less compressible pressure media or pressure media which cannot be compressed at all, the external force produced is a fixed quantity. But if vibration-like disturbance forces now occur on the outside, their force peaks can cause material wear or other undesirable effects. The pressure cylinder system according to the invention comprises dampers 4 which are arranged in the hydraulic inner area of the pressure cylinder system. By these dampers 4 with compression springs 5.1 and 5.2 as well as brake seals 2.3, the piston 2 with piston rod 3 is spring-mounted damper-like in any working position. External force peaks are thereby dampened to quantities which can be controlled and are no longer damaging. <IMAGE>

Title: Circuit arrangement for short-circuit protection of an invertor
Inventor: NIESEL NORBERT ING GRAD
IPC: H02H7/122
Filed: 1985-11-30
Abstract: In order to protect an invertor (WR) against a short-circuit, using an inductor coil (L), which is arranged between one pole of a DC voltage source (CD) supplying the invertor (WR) and a DC voltage connection of the invertor (WR), limits the rise of a short-circuit DC current and is bridged in the negative direction of the DC current by a diode (DD), it is intended to provide a DC quick-action switch which interrupts the current immediately when an overcurrent occurs which can no longer be commutated by the invertor (WR). For this purpose, a first thyristor (TD), which is likewise bridged by the diode (DD), is connected in series with the inductor coil (L), and a series circuit comprising a second winding, in the same direction, of the inductor coil (L) with a pre-charged capacitor (C) and a second thyristor (T) is connected between the two poles of the DC voltage source (CD). If a dangerous overcurrent occurs, the second thyristor (T) is triggered while the triggering pulses, which are present during operation, for the first thyristor (TD) are blocked. <IMAGE>
