Abstract: In a device for forwarding material for treating machines it is proposed that a secondary carriage is mounted on a main carriage, that said secondary carriage is taken along by a transmission spring system of the main carriage and that the secondary carriage cooperates with carriage stops. In this manner, the aim is to reduce the mass impinging on the carriage stops. According to a further development of the invention it is proposed that the speed of impact of the secondary carriage on the carriage stops is also reduced.

Abstract: The microscope has an observation light path (B), which is deflected by a reflector and extends diagonally upwards in the direction towards the viewer, and a photographic light path (P1) extending horizontally in the housing of the microscope. The photographic light path (P1) is reflected out through an optical element (16; 116), which seen in the direction of the light is arranged behind the reflector (14) deflecting the observation light path in the diagonally extending part of the observation light path (B). The observation light path passes in a straight line through this element. This structure enables the stage height of the microscope to be greatly reduced. <IMAGE>

Abstract: An electronic component (10) having a flexible substrate (32) with conductive traces (34) thereon may have the leads separated into arrays (24) that are shaped to contact and be surface mounted to the bonding lands (16) on a printed circuit board (PCB) (12). The flexible substrate (32) , such as polyimide, adheres to the traces (34) and is formed into lead arrays (24) with them. The lead arrays (24) thus keep portions of the leads and the outer bonding areas (50) corresponding thereto aligned with respect to each other during handling and mounting to the PCB (12). An alignment mechanism (24/28) may be optionally present on the lead arrays (24) that mates with a corresponding mechanism (30) on the PCB (12). The package body (18) itself may be overmolded, assembled from prior parts, etc. Another alternate version includes test points (46) on the perimeter of the substrate(32) beyond the outer bonding areas (50) that may be used to test the device, such as an integrated circuit chip or die, at an intermediate stage in the assembly process. The periphery (44) and test points (46) may be sheared away before the device (10) is mounted to the PCB (12). A variety of outer bonding area pitches may be provided on the same device (10) with test points (46) of a standard pitch. The relatively inexpensive device (10) is thin and easily mounted by conventional techniques.

Abstract: In apparatus for recording/reproducing a component video signal having a luminance signal (S YH ) of a wide frequency band so as to be reproducible to provide a picture of high resolution and a chroma signal (S CL ) in a chroma band included in the frequency band of the luminance signal (S YH ) substantially below the high end of the latter, a recording signal processing circuit (20) separates (21,10) from the luminance signal (S YH ) a slant direction luminance signal (S HY ) in a frequency band that includes and extends substantially above the chroma band, whereupon the luminance signal (S YH ) is suppressed (12) by the slant direction luminance signal (S HY ), and a component of the slant direction luminance signal (S HY ) in the chroma band is frequency-­converted (23,25,26) to a higher band and is frequency interleaved with the suppressed luminance signal (S YK ). The chroma signal (S CL ) is frequency interleaved (9) with the suppressed luminance signal (S YK ) and is then added (13,29) to the latter and to the frequency-converted slant direction luminance signal (S LY ) to form the video signal (S ADD1 ) which is to be recorded. In the reproducing mode, a circuit (40) for processing the reproduced video signal separates (6,7,41-45) therefrom the chroma signal (S CK ), the frequency-converted slant direction luminance signal (S LY ) and the suppressed luminance signal (S YK ), whereupon the separated frequency converted slant direction luminance signal (S LY ) is frequency-reconverted (47,49) back to the chroma band and into frequency interleaved relation with the suppressed luminance signal (S YK ), and the reconverted slant direction luminance signal (S SI ) and the separated suppressed luminance signal (S YK ) are added (51) to provide a luminance signal (S SHO ) which, with the separated chroma signal (S CK ), forms a reproduced component video signal.

Abstract: A system for maintaining the reliability of shared data structures, such as message queues, in a multi-processor data processing system is disclosed. The system includes a plural­ity of virtual memory- type processor units (10) in which the processors share virtual memory and can access each one of a plurality of virtual memory segments by the same virtual memory address. The system assures the reliability of system-­wide shared data structures in the event of a failure of one of the processors by maintaining at least two copies of each data structure and by maintaining two copies of a table used in locating such data structures. The system updates copies of such shared data structures that are stored in at least two different processing units with the results of a specified data processing transaction, which may have affected the information in such data structures, in a manner to insure that either identical updates occur or no update occurs. The system further insures that any changes that might have occurred in the information stored in the data structure prior to the end of an aborted transaction is returned to the initial state to permit the transaction to be retried.

Abstract: An array antenna (20) that avoids the generation of grating lobes or second order beams is formed of a two-dimensional array of radiating elements (40) disposed in parallel rows (22) and parallel columns (24), each of the radiating elements being formed as slotted apertures within a top broad wall (28) of a waveguide (26). The width of the broad wall is many times greater than the height of a sidewall (32, 34) of the waveguide, the waveguide having a rectangular cross section. A wave launcher (46) connected to a first end of the waveguide launches a higher-order mode of electromagnetic wave wherein the order of the mode is equal to the number of columns of the radiating elements. A set of vanes (48, 48A) upstanding from a bottom wall (30) of the waveguide extend partway towards the top wall to provide values of inductance and capacitance which resonate at the resonant frequency to inhibit reflection of the electromagnetic wave from individual ones of the vanes. Each vane extends in a plane perpendicular to the sidewalls, individual planes of the vanes bisecting slots (40) of the radiating elements, the slots being arranged parallel to the sidewalls. In each column, the locations of vanes are staggered from side to side so as to offset a path of propagation of the wave in the vicinity of the radiating element to reverse a sense of coupling of electromagnetic power from the wave to the radiating element. This produces a uniform phase front from radiations from all of the radiating elements.
