Abstract: Communication paths in a digital key telephone system are operated by sequentially transferring bit states from origin channels (11) associated with communication ports (19) to exclusively dedicated time slots in a parallel transmission medium (10). Time slot bit states are selective stored at designated memory locations (701) corresponding to destination channels associated with the communication ports. The memory locations are read in synchronizm with the channel occurrences and bit states from the designated memory locations are asserted in the corresponding channels (11), any remaining channels having predetermined bit states asserted therein.

Abstract: A method and means for extending the collation func­tions of a sorting program (SORT) enable the program to permute, combine, or filter input records having collating characteristics that are not recognized by the SORT pro­gram. The extension includes provision of an extended function support program (EFS) that can be invoked by and concurrently executed with the sorting program. The EFS program is provided with a modality for modifying control statements received by the SORT program but executable only against records having the non-recognized collating charac­teristics. The EFS program modifies such control statements to a form executable by the SORT program. The EFS program also is provided with the capability of modifying the collating characteristic fields of records which are to be processed by the SORT program, the modification resulting in the provision for the records of counterpart collating characteristics recognized by the SORT program. The SORT program is thereby enabled to SORT/MERGE input strings of records with non-recognized collating characteristics into output strings including such records. The EFS program is also invoked by the sorting program to perform conditional filtration of input records having non-recognized collating characteristics, which enables the SORT program to assemble an output list of filtered records with non-recognized characteristics. This permits the SORT program to perform INCLUDE/OMIT functions on records with non-recognized collating characteristics.

Abstract: A pattern data generating system including a processor (12) for writing in a bit map memory (13), on the basis of input data, point of all lines to be filled or painted along a scan direction which is one direction on the bit map memory (13). This writing is performed such that a point (S6 in Fig. 1) on each line is written as one of two end points thereof while a point (S14 in Fig. 1), offset by one point in the scan direction, is written as the other of the two end points. The pattern data generating system also includes a pattern data generating circuit (30) for, if w (w is a positive integer) points b0, b1, ..., b(w-2), and b(w-1) are present on one scan line, writing EXOR of data of points b0, b1, ..., b(j-1) at positions corresponding to points b(j) (j is not less than 0 and less than w). Similar EXOR data writing is performed by the pattern data generating circuit (30) for all the scan lines. Then, pattern data, in which the area surrounded by the closed curve is filled or painted, is obtained.

Abstract: A switched-mode power supply for a light source whose brightness is controlled, having a rectifier which produces a half-wave rectified voltage at first terminals, having a smoothing circuit which produces a smoothed DC voltage at second terminals, having two push-pull semiconductor switches, associated with a high-frequency generator, whose control inputs are each coupled to a transformer winding, and having a first switching element, which is coupled to the DC voltage input and is voltage-dependent, for triggering a semiconductor switch. The technical problem is producing a switched-mode power supply which permits brightness control by controlling the high-frequency generator without the high switching loads of phase chopping. A control input is fed via a first switching stage (81). A capacitor (44) with an adjustable load resistor (46) is connected to the second terminals (54, 55) of the DC voltage. The charging voltage of the capacitor (44) is applied to the input of a second switching stage (43) whose output switches off the first switching stage (81) and the voltage-dependent first switching element (15). A zero-voltage identifying circuit (56) is connected to the first terminals (5, 6) of the half-wave rectified voltage. The output of the zero-voltage identifying circuit (56) controls a discharge stage (57) for the charging capacitor (44). <IMAGE>

Abstract: In a video camera having an automatic focusing function, a focus evaluating value is calculated as the sum of first and second focus evaluating values extracted using outputs of two filters having different cut-off frequencies, and a relative ratio of the first and second focus evaluating value is also calculated. This relative ratio is compared with a predetermined reference value. Considering a case in which the focus evaluating value is below this reference value after an object is brought into focus, even if the focus evaluating value does not change, an auto-focus operation is resumed. On the other hand, considering a case in which the relative ratio is above the reference value, even if the focus evaluating value changes, the auto-focus operation is not resumed. In addition, even if the focus evaluating value reaches a maximum in the auto-focus operation, the auto-focus operation is not terminated if the relative ratio does not reach a predetermined reference value. Furthermore, the amount of slight movement of a lens in an object change confirming operation after bringing the object into focus is switched depending on the relative ratio. Additionally, it is determined whether or not the lens correctly moves toward an in-focus position by determining the increase or decrease of the relative ratio.

Abstract: A method and a device are described for printing all round a metallic hollow body, in particular a can body, by means of thermal transfer printing, wherein ink particles arranged on an auxiliary support are introduced by diffusion, for example, into a dye-receptive layer on the can body using heat and pressure. The method and device are designed in such a way that the can body is heated up briefly with the auxiliary support applied and the transfer process thus initiated is subsequently completed at a preferably dropping temperature. Thus by suppressing the lateral migration of the dye molecules during the transfer process, visually sharp images on the can body and a satisfactory closed print of the overlapping region of the auxiliary support are achieved.

Abstract: A dimming switch terminal unit for monitoring a dimming-up switch and dimming-down switch and a dimming control terminal unit for performing dimming control of an associated light load are connected to a central control unit through a two-wire signal line. The central control unit accesses each of the terminal units to perform time-divisional multiplex transmission of monitor data and control data therebetween. When the dimming-up switch or dimming-down switch is depressed, the central control unit detects monitor data indicating the switch depression and sends to the dimming control terminal unit control data instructing it to start dimming-up or dimming-down control. The dimming control terminal unit continues to dim up or dim down the associated light load until the dimming-up switch or dimming-down switch is released and the dimming control terminal unit receives control data instructing it to stop dimming up or dimming down the light load.
