Title: Colour graphics data processing apparatus
Inventor: HOSHINO MASAAKI
IPC: H04N1/62
Filed: 1985-11-27
Abstract: Apparatus for processing colour graphics data converts an analog video information signal to a digital signal and stores one frame of the digital video signal corresponding to a desired still picture for display on a video monitor/receiver (4) upon being read out from the store (32). The still picture read out from the store (32) is also fed to a microcomputer (1) in which a colour picture corresponding to the displayed still picture is stored in a memory (13) so that it may be displayed on the monitor (4) and visually compared with the original picture. The data processing apparatus specifies a movable portion of the displayed picture, and the appearance frequencies of respective colours in a plurality of picture elements contained within that specified portion are counted. These appearance frequencies are used to generate a limited number of colours in a colour palette (17). When defining the colours of the colour palette (17) the data in the microcomputer memory (13) are converted to a computer graphics bit length and read out through the colour palette (17) for display on the monitor (4).

Title: Carrier signal level monitoring
IPC: H04B7/15
Filed: 1979-08-08
Abstract: In a satellite communications transmission system employing multi-carrier operation, the individual carrier powers are measured by coupling out a portion of the sum carrier signal in the vicinity of the antenna feed and feeding this portion to a mixer (M) whose converter oscillator (SYN) consists of a synthesiser controlled by a control signal generator (STG), and is consecutively switched over to the middle frequencies of the individual carrier signals, the modulation products converted down to zero frequency being passed to a display device (AZ) via a selective network (N) which is switched over in synchronism therewith to present selected low-pass characteristics, one for each channel. The display device possesses a display instrument for each carrier signal, which are connected via separate stores selectively fed via a switching matrix in accordance with the timing of the control signal generator. <IMAGE>

Transverse rails 30 are engaged by retractable rollers on the machine and enable it to transfer from one mould to the other. After supplying liquid bitumen to the moulds, which include longitudinally adjustable transverse walls 4, the machine is driven stepby-step a distance equal to the length of a desired slab in the direction of the arrow F, Fig. 4, whereupon an inclined blade 13 mounted on rollers 15 lifts a strip of desired length from a mould bottom enabling it to be received on a support 43. A carriage 17 supported on the machine by rollers on transverse rails 35 carries a cutter blade 19 and is driven transversely to cut the strip from the block; the carriage is then returned to its initial position whereupon a pusher member 20 is moved downwardly to engage one end of the severed strip. The carriage is now fed transversely step-by-step a distance equal to the desired width of the slab to push the end of the strip on to a tray 24 suspended on an endless conveyer 25, and a cutter 22 removes a slab of desired width from the strip. The slab is then raised by the conveyer and pushed towards a packaging machine from which the packaged slab is fed to a stacker.
