Title: A driving circuit for permanent magnet type DC motor
Inventor: FUJIOKA YOSHIKI
IPC: H02P3/14
Filed: 1979-11-27
Abstract: isclosed is a DC motor drive circuit adapted to prevent thyristor commutation failure when a thyristor controlled three-phase full-wave reversible bridge undergoes a transi- siton in operating mode from a power invention mode to a power rectification mode. The drive circuit includes a thyristor-controlled threephase full-wave reversible bridge (2, 3) whose firing phase is controlled in accordance with a speed deviation between the actual speed (TSA) of a DC motor and a command speed (VCMD); polarity discrimination means (9f) for discriminating the polarity of the speed deviation; firing phase narrowing means (9i) operable in the power inversion mode to narrow the thyristor firing phase down to a minimum firing phase due to a reversal in the polarity of the speed deviation; detection means (9j) for detecting an intermittence in armature current (I A ); and blocking means for blocking firing of the three-phase thyristor-controlled inverter for a prescribed period of time when the intermittence of the armature current (I A ) has been detected; the operation mode of the inverter being changed over from the power inversion mode to the power rectification mode after the lapse of said prescribed time period.

Title: Drive control for an elevator
Inventor: SCHRODER JORIS DR ING
IPC: B66B1/16
Filed: 1980-09-19
Abstract: A drive control for transportation systems, especially elevators or the like, improves the stopping accuracy of the elevator cabin at a storey or floor of the building. A reference value transmitter operated by a digital computer produces step-like successive travel curves and displacement path-reference values operatively associated with such travel curves and feedable to a regulation circuit. Connected with the reference value transmitter is a stop initiation device, which during initiating the stop or halting of the elevator, forms from a possible target path produced by the reference value transmitter and a target path corresponding to a target storey a target error. This target error is infed to a stop correction device connected with the reference value transmitter and the stop initiation device, which while utilizing the target error modifies by interpolation the travel curve which is to be produced by the reference value transmitter in a manner such that there is available for regulation an optimum travel curve to the target storey. An arrival correction device which further improves the halt or stop accuracy of the elevator, forms from the elevator cabin site determined at a cabin displacement path counter and the storey site of the target storey a difference which, for the purpose of further correction of the displacement path-reference value, is infed to the stop correction device. This drive control, apart from being used with elevator systems, for instance also can be employed for track-bound horizontal systems.

Abstract: In the case of gripping heads secured rigidly on a motion unit for manipulators, damage can occur to the workpiece, the workpiece support or the manipulator in the event of incorrectly positioned workpieces or workpieces exhibiting variations in dimensions. Such damage is eliminated by suspending the base plate (7) carrying the gripper arms (8) flexibly on the fixing flange (1) of the gripping head. Spring means (4, 6) between the base plate (7) and the fixing flange (1) bring the base plate (7) into a defined position (Z) relative to the fixing flange (1) as soon as there are no longer any external forces acting on the gripper arms (8) or the base plate (7).   <IMAGE>

Abstract: A process for preparing adenine by reacting an arylazomalononitrile with formic acid or its derivatives in the presence of ammonia and then subjecting the intermediate pyrimidine derivative to a reaction under catalytic reduction condition. Adenine can be prepared in high purity and high yields without isolating the intermediate pyrimidine derivative, when ammonia is removed before conducting the reaction under catalytic reduction condition. Also, the preparation of adenine in high purity and high yields can be more surely attained, when the arylazomalononitrile prepared under a specific condition is employed as a starting material or when Raney nickel is employed as a reduction catalyst in combination with active carbon. The produced adenine is effectively purified by separation of insoluble materials from an aqueous hot solution of adenine adjusted to pH 7.5 to 9.0 and formation of a mineral acid salt of adenine followed by decoloration by heating in the presence of active carbon.
