Abstract: In a method of manufacturing a semiconductor device, when contact holes are to be formed in an insulating film (110) formed on a monocrystalline or polycrystalline semiconductor layer (108), the contact holes can be formed using a polycrystalline semiconduc­tor layer formed on the insulating film as a mask. Therefore, the lithographic step of forming the contact holes in the insulating film formed on the monocrystal­line or polycrystalline semiconductor layer can be eliminated.

Abstract: An energy efficient process for hydrolysing lignocellulosic materials which comprises using a primary system by providing a start-up energy input to operating saturated steam conditions and thereafter operating the primary system with substantially constant energy input, the condition of the hydrolysing saturated steam being controlled by water injection and/or steam bleeding from the primary system. The dwell time of the solids stream in the primary sustem is controlled by controlling its passage with flashing off of steam into a secondary system where drying occurs together with some small measure of hydrolysis in a lower pressure superheated steam environment, there being an energy input into the secondary system using steam bled from the primary system. 
     The output solids material stream is preferably capable of being self polymerised into a formed shape  eg  a board.

Abstract: A method and apparatus are disclosed for randomly selecting and automatically testing electronic components such as surface mount passive electronic components. A detachable hopper is utilized to contain a plurality of randomly oriented electronic components which are agitated pneumatically and urged by vibration and gravity into a uniform orientation within a groove in an inclined track plate. A seal plate acts in conjunction with the groove within the track plate to form an elongate throat passage which is periodically cleared to prevent clogging by pulsating pneumatic pressure. A component detection circuit is utilized to detect the presence of an electronic component at a predetermined testing postition and a pair of movable conductive probes are then urged into contact with the component to permit testing. In response to a successful test the component under test is then ejected pneumatically back into the detachable hopper. In the discussed embodiment of the present invention, an unsuccessful test will require the unsatisfactory component to be manually removed from the testing position by the operator of the apparatus.

Abstract: Signal distortion in fiber optic systems is compensated for by forming decisions as to the transmitted information as a joint function of the received signal and of a feedback signal. The latter, in turn, is a function of decisions made for at least one signal transmitted over the fiber. The feedback signal determines the value of a threshold to which the received signal is compared in order to generate the decisions.

Abstract: For controlling the brightness of a matrix-addressed flat panel CRT display (70) of a type having intersecting column and row conductors (72,74) forming, respectively, the cathode and gate electrodes of a field electron emission array (76), the brightness control effected by controlling both the duty cycle and the voltage applied to the drive lines of the intersecting conductors (72,74). A periodic staircase waveform having progressively increasing voltage steps (VROW) is sequentially applied to the row conductors (74). The voltages (VROW) at each of the steps are selected to enable electron beam currents which proved brightness levels which are twice the brightness of the previous step. Binary-coded video brightness data are simultaneously applied to all of the column conductors (72). The combined voltages at the intersections of the selected conductors cause a sequence of electron emissions onto luminescing means which result in a corresponding sequence of illumination intervals. The human optic system integrates this illumination sequence into the selected brightness level. In addition, the overall brightness of the display is controlled by gating (84) the waveforms for the column conductors (74) with a pulse train comprising a sequence of adjustable, uniform-width pulses from an adjusting one shot (88).

Abstract: A decoder (10) for decoding CCITT compressed image data separates all the incoming codes into short codes and long codes, the short codes being sent to a short channel decoder (25), and the long codes being sent to a long channel decoder (28). At each decoding cycle either the long channel decoder or the short channel decoder is active. The short channel decoder has a twin set decoder (36) which decodes two short codes in parallel and guarantees two bits of decompressed data per decoding cycle. If the decoding of a first code generates a decompressed data of only one bit, then the decompressed data of a second code will be combined with the first decompressed data and the combination will be sent out. The long channel decoder decodes the long intermediate codes, which always generate at least four bits of decompressed data.
