Patent EP-0601419-A1 (EP)
Inventor: SCHULZ HARTMUT
IPC: H02P21/06
Filed: 1993-11-26
Abstract: A circuit arrangement is provided for driving a brushless DC motor (10), which has a radially magnetised rotor (20), with the aid of a microprocessor. This circuit arrangement has a first regulator (36) and a second regulator (38) to whose inputs the differences between in each case one required current value (idd, iqd) and one actual current value (idm, iqm) of the virtual currents flowing in the direction of the magnetisation and transversely with respect to the direction of magnetisation are connected, and which form associated regulator output signals (Ud, Uq). A rotation-angle sensor (44) supplies angle-position information on the angular position of the rotor (20) of the DC motor (10). First transformation means (46) are used to carry out an "inverse PARK transformation" in order to convert the regulator output signals (Ud, Uq) into three-phase voltage values (UR<*>, US<*>, UT<*>) (R, S, T are equivalent to R, Y, B in the British system) for producing a rotating field in the stator (12) of the DC motor (10), the angle-position information obtained from the rotation-angle sensor (44) being connected to the transformation means (46) in addition to the regulator output signals. A converter (48) converts the three-phase voltage values into three-phase currents which are connected to three windings (14, 16, 18) of the stator (12) of the DC motor (10). At least two currents (iSm, iRm) are measured in the windings (14, 16). Second transformation means (54) are used to carry out a "PARK transformation" in order to convert the said two currents in the windings (14, 16) into the said required current values (idm, iqm) for the virtual currents. In order to reduce the technical complexity in the case of such a circuit, the first and second transformation means (46, 54) have a function-term memory (64) in which two blocks of function terms for the transformations are stored, for each transformed variable, at addresses which are in each case formed by the angle-position information as the first address element and one of the variables to be transformed as the second address element. A first of the variables to be transformed can be connected via a multiplexer (116) to the function-term memory (64) on the one hand as the second address element for a function term of the first block and subsequently as the second address element for a function term of the second block. A register (132) is used for buffer storage of the function term allocated to the angle-position information and to the first variable to be transformed. In addition, an adder (134) is provided to which the buffer-stored function term from the register (132) can be connected as well as that function term which is allocated to the angle-position information and the second variable to be transformed. A further simplification is achieved by the transformations being carried out partially digitally and partially in an analog manner. <IMAGE>

Abstract: An image developing apparatus using a laser beam source used when producing an original plate for producing a master disk of an optical type recording disk such as video disk and the like. 
     A disk base plate 3 formed thereon with an exposed optical sensitive film 2 is rotated while developing solution 6 is supplied on the optical sensitive film 2 to remove the exposed parts of the film. To monitor the development, a laser beam 8 from a laser beam source 7 is irradiated on an exposed portion of the optical sensitive film 2 which is being dissolved and zero and first order diffraction light 9 and 10 are detected by first and second detectors 11 and 12. Light amount control means 13 are provided to maintain constant the detected level of zero order light by controlling the laser, and the first order light is used to detect a stop time for the development. Stabilization of the zero order light eliminates fluctuations from external sources such as dust, mist etc. The incident light may be controlled by the control means 13 either directly if a semiconductor laser is used or by using a modulator in the light path if a gas laser is used. The semiconductor laser may have a short coherence length which reduces fluctuations caused by multiple interference effects within the glass disk base plate 3 whose thickness can vary.

Abstract: Hollow synthetic monofilament yarns (18) are used in the construction of a base fabric (21) for a papermakers wet felt (20). The synthetic hollow monofilament yarns (18) have selected interior void, compressibility and resiliency characteristics and are interwoven with other yarns (1-16) to form a woven base fabric with the hollow monofilament yarns predominating, on at least the paper carrying side of the base fabric. The weaving and finishing of the base fabric (21) results in the hollow monofilament yarns (18) retaining a substantially unflattened cross-section. Accordingly, substantially unflattened portions of the hollow monofilament yarns (18) predominate the paper carrying side of the base fabric thereby providing a cushioning surface which is compressibly resilient to assist in the dewatering of the aqueous paper web as it is transported through a press nip during the manufacture of the paper. Hollow nylon monofilament yarns having approximately 18% internal core void have been found to exhibit the desired compressibility and resiliency characteristics. Preferably a fibrous batt is needled to the base fabric to finish the wet press felt.

Abstract: A heat exchanger tube (10) for use in an application, such as a shell and tube type air conditioning system condenser, in which a fluid flowing through the heat exchanger external to the tubes condenses by transfer of heat to a cooling fluid flowing through the tubes. The tube (10) has at least one fin convolution (22) extending helically around its external surface (13). Multiple axial notches (23) are impressed into the fin at intervals along its extent. Because the notches (23) are impressed and not cut into the fin, material displaced from a fin to form a notch forms lateral projections (24) from the walls of the fin. The notched fins provide increased external heat transfer surface area on the tube, destabilize the film of condensate on the tube external surface, thus causing the film to be generally thinner, and promote condensate drainage from the fins and off the tube and thus increase the heat transfer performance of the tube (10).

Abstract: In a first starting phase, the weaving machine is run up according to a control program independent of the weaving program, until it has reached the dynamic operating state corresponding to normal weaving operation. In the subsequent second starting phase (II), the selvedge (15) is shifted into a set-aside position (15a), of which the distance x1 from the beating-up edge is selectable. With this set-aside position (15a) being maintained, a number of weft insertions are executed under normal operating conditions and the selvedge (15) is guided into the beating-up position, so that, with the weft thread last inserted, all the weft threads inserted in this phase (II) are beaten up. The formation of run-on points in the fabric is thus avoided. <IMAGE>
