Abstract: Drawer cupboards with draw frames, on which tool or magazine boxes rest in a freely removable manner, are commonly mounted in workshop or service trolleys. When the trolley is tilted and because of jolting during movement, there is the danger that the drawers mounted so as to run easily will roll out by themselves. The drawers therefore have to be locked in their retracted end position. The object on which the invention is based is to provide a locking and unlocking device which is simple to handle and which also prevents the possibility that, during unlocking, in addition to the drawer grasped, the other drawers will move out by themselves. To achieve this object, each drawer frame (3) is equipped with an individual unlocking device. The unlocking knob (10) of this individual unlocking device is arranged in the end wall (11) of the drawer frame (3) within handling range of the hand holding the box (4) by its carrying handle (5). <IMAGE>

Abstract: A method for detecting a prospective contour point of an irradiation field comprises the steps of detecting an image signal representing a radiation image from a recording medium which has been exposed to radiation over a limited irradiation field in order to record the radiation image thereon, and obtaining digital image signal components corresponding to image information stored at respective positions on the recording medium from the image signal. A characteristic value which represents the characteristics of the distribution of the values of the digital image signal components representing image information stored on a single line on the recording medium is calculated. A predetermined threshold value is adjusted on the basis of the characteristic value, and differentiation processing of the digital image signal components is carried out along the line. A point, for which the absolute value of a corresponding differentiated value obtained by differentiation processing exceeds the threshold value, is detected as a prospective contour point of the irradiation field.

Abstract: In a dot-matrix printer including a wire-dot print head (105) having print wires which print dots by impact on a printing medium, and a sensor (51) for sensing the position of the print wires and generating signals indicating the position of the print wires, a parameter determining a printing force with which each of the print wires impacts the printing medium is set. A control and driving circuit (104) drives the print wire responsive to the signals from the sensors (51) and the set parameter. The combination of the feature of setting a parameter for controlling the printing force and the feature of detecting the position of the print wire enables the control over printing force with a high reproducibility. So printing with an optimum printing force is ensured.

Abstract: In a computer system, a plurality of input/output processors (IOP's) are connected via an asynchronous input/output bus, called an "SPD" bus, to one side of an input/output interface controller (IOIC). The other side of the input/output interface controller (IOIC) is connected to a storage controller (SC) via a synchronous bus called an "adapter" bus. The storage controller (SC) is connected to a common system memory and possibly also to an insturction processing unit. The SPD bus, which comprises three sub-buses and a control bus, conducts signals between each input/output processor (IOP) and the input/output interface controller (IOIC) in an asynchronous "handshaking" manner. The adapter bus, which comprises two sub-buses and a control bus, conducts signals between the input/output interface controller (IOIC) and the storage controller (SC) in a synchronous manner. The input/output interface controller (IOIC), interconnected between the SPD bus and adapter bus, functions as a buffer between the faster synchronous bus and the slower asynchronous bus. The input/output interface controller (IOIC) also comprises at least one shared DMA facility for executing DMA storage operations requested by the input/output processors (IOP's) via the SPD bus. Each shared DMA facility includes a buffer for control information and data to be transmitted between the storage controller (SC) and one of the input/output processors (IOP's) and a bus interface coupled to the buffer, to the adpater bus and   to the SPD bus for independently transferring the control information and data between the buffer and the storage controller (SC), on one hand, via the adapter bus, and between the buffer and the one input/output processor (IOP), on the other hand, via the SPD bus. In this manner, the SPD bus can be released for utilization by other input/output processors (IOP's) connected thereto during a period of "storage latency" after a DMA storage operation has been initiated by one input/output processor (IOP).

Abstract: For using such a FEC method in systems of the most varied type, the invention provides that the serial binary data stream to be transmitted is supplied to a device for rate adaptation and serial/parallel conversion, in which, on the one hand, the data rate is increased to the transmission rate, forming free spaces for accommodating redundancy bits, and, on the other hand, from the serial data stream a corresponding number of parallel data streams is generated, one half of which in each case forms the I and Q channel, respectively. The redundancy spaces in this arrangement are located in the least-significant bits of I and Q channel. The higher-significance bits of I and Q channel directly control the associated inputs of a quadrature modulator, while the least-significant bit is supplied to the relevant input in each case via a multiplexer. In addition, the least-significant bit of I amd Q channel is in each case supplied to a coder, each of which looks at a particular number of incoming bits and from these generates one or several redundancy bits in accordance with the coding rule of a particular basic code. These bits are inserted into the places provided for this purpose in the I and Q channel, respectively, with the aid of the two multiplexers.
