Abstract: An improved burn-in board cartridge for use in burn-in and 
testing of IC packages in an automated burn-in and test system is 
disclosed. The cartridge includes printed circuit cards mounted 
on a single or both side faces of the cartridge, thereby permit­
ting IC packages to be mounted on either or both sides of the 
cartridge. The cartridge includes a sturdy frame holding in 
place the printed circuit cards and providing strength to reduce 
damage to the circuit cards. Attached to the frame are rails 
which are used to position the cartridge in various apparatus 
such as burn-in chambers. Cooling tubes and electrical com­
ponents can be placed inside the two-sided cartridge, between the 
printed circuit cards. The burn-in chamber is divided into zones 
with each zone having a number of slots into which a burn-in 
board is placed. The chamber includes rotating air diverters 
positioned at each end of a zone which are capable of channeling 
the heated air within the chamber around any one zone. Each zone 
has an access door to permit loading and unloading of burn-in 
boards from any zone. An automated handler is provided to 
automatically insert and remove the burn-in board and cartridge 
from various units in the system. The handler includes a 
generally T-shaped member inserted into apertures on the burn-in 
board by rotating the handler with a cam lever and a first cam 
follower. A plurality of handlers may be used to grasp and 
insert a number of burn-in boards sequentially, using a second 
cam lever and cam follower.

Abstract: A differential transconductance amplifier includes 
two error amplifiers (20-30) which provide an error correction 
current which linearizes a main differential 
amplifier (12,14). Two reference transistors (10, 16) coupled to the 
main differential amplifier provides two sets of input 
voltages to the two error correction amplifiers. The 
output currents of the main amplifier and the two 
error correction amplifiers are summed to produce a 
linearized output.
Patent EP-0305106-A3 (EP)
Title: Bus error processing system
IPC: G06F11/00
Filed: 1988-08-17
Abstract: A bus error ascribable to a bus master module (2) other than a central processing unit (CPU) (1) is set as a specified factor for an exception process. When the exception process is requested, the CPU (1) executes a corresponding service program for the exception process without executing a process for altering and setting mask bits, which would be executed for a normal interrupt request. Thus, the exception process request specific to the bus error is not undesirably refused by interrupt requests etc., being accepted before the bus error. Furthermore there is a reduction in the time which is expended before the start of the run of a service program corresponding to the bus error, with the result that the reliability of the process for the bus error attributed to the predetermined bus master module (2) other than the CPU (1) is enhanced.

Patent EP-0376004-A3 (EP)
Title: Variable length pipe operations sequencing
IPC: G06F9/38
Filed: 1989-12-05
Abstract: A sequence of instructions made up of stages is 
executed sequentially by the processor in a first mode 
(stack mode) such that, the Nth stage of the Ith 
instruction is processed simultaneously with the N+1 
stage of the I-1 instruction. Similarly the N+1 stage 
of the I-1 instruction is processed at the same time 
as the N+2 stage of the I-2 instruction and so on. 
The processing unit maintains the execution of in­
structions in the same sequence as they were received 
by the processing unit by executing all sections of an 
instruction. Even though a stage may not be required 
for execution of a particular instruction, the pro­
cessor must wait (i.e., execute a null instruction) 
for a time equivalent to a stage before processing the 
next stage. The invention provides a second mode 
(non-stack mode) of execution such that unneeded or 
null instruction stages are bypassed without the 
processing order of the execution sequence being 
disturbed. Sequence logic determines the conditions 
necessary for a sequence of instructions to be 
executed in one or the other modes of execution. The 
processor switches back and forth between stack mode 
and non-stack mode of processing in order to keep the 
instructions executing in the same order as they are 
received by the processor. The non-stack mode of 
execution allows the processor to utilize wasted time 
and improve the performance of the processor while the 
stack mode avoids the need for complex and expensive 
logic to keep track of out of order instruction 
processing.

Title: Tube clamping device for cylindrical workpieces
IPC: B23K9/028
Filed: 1989-07-07
Abstract: The clamping device for holding cylindrical 
workpieces having a nominal radius R which varies from 
a minimum of (R-A) to a maximum of (R+B), where A and 
B are the limits of the tolerance range for the 
nominal radius, includes opposed clamp halves (22,24) 
each having a clamp face (22a) adapted to be moved 
towards and away from one another and each of the 
clamp halves (22,24) carrying a rigid collet element 
(48,50) adapted to engage on opposite sides of 
cylindrical workpieces when the clamp halves (22,24) 
are moved towards one another. Each of the collet 
elements (48,50) has a semi-cylindrical clamping 
surface (56) extending inwardly from the clamp face 
(22a) of the respective clamp half (22,24). Each 
semi-cylindrical clamping surface (56) has a radius 
being offset outwardly of the clamp face of the 
respective clamp half an amount at least equal to 
(A+B). Preferably, the centre of the radius is offset 
an amount at least equal to (A+B+C), where C is the 
tolerance deviation permitted to the radius (R+B).  
     In a modification (Figs. 8 to 10), each clamping 
surface (66) is comprised of individual surface 
portions (68,70) mounted for independent flexing 
movement to allow the collet elements (60) to further 
compensate for variations due to workpiece tolerances.

Filed: 1989-11-01
Abstract: A dyesheet for thermal transfer printing comprises a substrate supporting a transfer coat comprising a plurality of uniform panels containing different coloured thermally transferable dyes, and a further panel in which instead of a coloured dye there is a thermally transferable colourless absorber of ultraviolet radiation. Using such a dyesheet, a layer of UV absorber can be applied very simply as an extension of the printing process, by causing the receiver to pass through the printer once more, in contact with the further panel, essentially as though the UV absorber were merely a further colour to be added to the print.
Patent EP-0378180-A3 (EP)
Title: Method and device for cleaning blanket cylinders in rotary web-printing machines
IPC: B41F35/06
Filed: 1990-01-09
Abstract: When washing the blanket in an offset printing machine, the time the cleaning liquid is allowed to act on the ink residues and the paper dust is important. In order to save time and waste paper, provision is made for a further application of cleaning liquid on the side of the blanket cylinder (3) opposite the washing beam (4). Thus the prespraying surface is larger and the residence time of the cleaning liquid on the blanket is longer until the wet soiled places come to be wiped off. The wiping-off takes place using a cleaning cloth (5) which absorbs the dirt. Further removal of the dirt takes place in the web-fed printing process via the web (1) which runs off in contact with the blanket cylinder (3). The efficiency of the blanket washing is increased. The distribution of the cleaning liquid over several places on the circumference of the blanket cylinder (3) leads to the desired high feed rate of cleaning liquid. The respective quantity per tube is variable. <IMAGE>

Title: A method and apparatus managing tasks
IPC: G06F9/48
Filed: 1990-05-25
Abstract: A method and an apparatus for scheduling tasks, which 
dispatches high and low priority tasks in predetermined 
intervals. High priority tasks are performed before low 
priority tasks while successively executed high priority 
tasks are counted up to a predetermined value. A low 
priority task is automatically dispatched and executed if the 
counted number reaches the predetermined value before all 
high priority tasks are completed. As a result, the method 
and apparatus can prevent low priority tasks from remaining 
without execution for long periods of time even when there 
are many high priority tasks to be executed.

Patent EP-0432626-A3 (EP)
Title: Circuit for monitoring an alternating current supplied light signal by direct voltages
IPC: B61L7/10
Filed: 1990-12-05
Abstract: At least one detector (M1, M2) is allocated in the setting mechanism to each go-signal light (F1, F2) of a light signal, which detector assumes a first switching state (-) when the signal light is illuminated and a second, active switching state (+) when the signal light is not illuminated; the second, active switching state of all detectors characterises the illumination of the stop-signal light (H). The illumination of a signal light (e.g. F1) is detected on the light signal via a light-current-controlled monitoring device (IG1) and transmitted with a pre-defined polarity to the setting mechanism via the feeding lines (LF1) of this signal light and the feeding lines (LH) of at least one de-activated signal light (H). When the stop-signal light (H) is activated, the monitoring voltage derived from the associated monitoring device (IG0) is applied to all detectors (M1, M2) via its own feeding lines and the feeding lines of all go-signal lights, out of phase with the DC voltages which can be injected via the monitoring devices (IG1, IG2) of the go-signal lights (F1, F2). When a go-signal light (e.g. F1) is activated, a voltage-controlled monitoring device (UG1) assigned to this signal light applies a monitoring voltage in phase with the DC voltage of the current-controlled monitoring device (IG0) of the stop-signal light via the feeding lines (LH, F2) to all detectors (M2) with the exception of its own detector (M1); an out-of-phase monitoring voltage derived from the light current is applied to this detector via changeover switches (K1.1, K1.2). A logical evaluation device evaluates the switching states of the detectors. The advantage of the circuit is that uniform switching modules (Mo1, Mo2) are used on the light signal for all go-signal lights without any individual connection with switching means of other signal lights. The circuit is intended for monitoring light signals in the railway network. <IMAGE>

packages from a nuclear power plant. The module 
includes a concrete precast container (12) with sidewalls 
(16) and a bottom (17), a concrete precast lid (14) 
removably disposed on upper edges of the sidewalls (16) to 
close the container (12), and a cylindrical one-piece 
seamless liner (22) abutting and covering the interior 
surface of the container (12). The liner (22) is provided 
with a plurality of ribs (32) formed integral with the 
liner (22) that extend along outside surfaces of the liner 
sidewalls (28) and bottom wall (30), and the ribs (32) are 
embedded within the concrete precast sidewalls (16) on the 
container (12). The plurality of ribs (32) can be T-­
shaped or dovetail shaped in cross-sectional area and may 
extend either longitudinally or circumferentially about 
the liner (22). The module is manufactured by 
first forming a one-piece seamless liner (22) 
including the ribs (32, 34) on its outer surfaces, 
placing the liner (22) in a mold for the module 
and thereafter pouring concrete into the module mold to 
completely fill the space between the liner (22) and 
the mold for embedding the ribs (32, 34) within 
the concrete. The integrally formed liner (22) is 
advantageously devoid of seams or weld joints and provides 
an additional barrier for nuclear wastes.
Patent EP-0391573-A3 (EP)
IPC: F02M65/00
Filed: 1990-03-21
Abstract: In an engine having direct fuel injection 
or injection at individual intake ports, the fuel 
injectors (10) are of the positive displacement type 
and are equipped with plunger (30) displacement 
sensors (42) to yield a displacement signal 
representing the quantity of fuel injected. This 
signal is used as a feedback to a closed loop PID 
control which compares the injected quantity to a 
demand quantity to determine an error and calculates 
a control pulsewidth which reduces the error 
eventually to zero. An open loop injector 
calibration of pulsewidth versus approximate fuel 
quantity is used as a base pulsewidth to which the 
closed loop adds a correction value.

Abstract: A method and an apparatus for encoding an input signal including the steps of
breaking down (601) the input signal into frequency components, separating (602) the
frequency components into a first signal made up of a plurality of tonal components and
a second signal made up of other components, the number of the frequency components
making up the tonal components being variable, encoding the first signal and encoding
the second signal, are disclosed. Also disclosed are a method and an apparatus for
decoding the encoded signals, and a recording medium (609) on which the encoded
signals are recorded. Tonal signals may be encoded efficiently depending on the
manner of distribution of their spectral energy to assure more efficient encoding on the
