Title: Process and apparatus for edge-hardening work pieces
IPC: C23C8/68
Filed: 1987-09-08
Abstract: Workpieces of metals or metal alloys are edge-hardened by a thermochemical treatment, especially by boronising by means of solid treatment agents in a fluidised bed which is generated in a reaction furnace by distributing a fluidising gas by means of an inflow tray, long tubular or stranded workpieces being moved through the fluidised bed with their surface to be treated being arranged axially in one direction. The figure shows an apparatus for carrying out the process, in which tubular workpieces are thermochemically treated on their inside in discontinuous operation with the use of adaptors. W1 and W2 here designate tubular workpieces with adjoining or interposed adaptors A1 and A2. The stationary tube furnace 5 has a preheating zone 6 and a heating zone 7. An inflow tray 9 is fixed in position in the interior of adaptor A1. At the start of working, the mounted unit of adaptors and workpieces is pushed, with the adaptor A1 at the front, through the preheating zone 6 in the direction of the arrow 15. The fluidising gas is blown in in the direction of the arrow 17 through the inflow tray 9 and the fluidised bed is generated from the granulated treatment material 14. <IMAGE>

IPC: H01L21/768
Filed: 1987-12-23
Abstract: An adaptive method and system are disclosed for 
providing high density interconnections of very large scale 
integrated circuits on a substrate 28. The procedure is 
performed in four basic steps: first an artwork representa­
tion for the interconnections of the integrated circuits is 
generated. This artwork representation is stored in a 
computer data base and assumes the integrated circuits to be 
at predetermined ideal locations and positions on the 
substrate. Second, using imaging (26,38,40), the actual positions of 
each integrated circuit on the substrate are determined. 
The actual positions of the integrated circuits are compared 
with their ideal positions to compute an offset and rotation 
for each integrated circuit on the substrate. Third, the 
computed offsets and rotations are then used to modify the 
artwork representation stored in the data base to account 
for the actual locations and positions of the integrated 
circuits on the substrate. Finally, the modified artwork 
representation is used to drive a direct writing laser 
lithography system (10,12,16,18,20,22,24) that actually forms the high 
density interconnections of the integrated circuits on the sub­
strate. The artwork representations are stored in computer 
data bases in vector form to minimize storage requirements. 
The laser beam produced by the lithography system is raster 
scanned on the substrate. Modulation of the laser beam is 
controlled by the real time conversion of the vector repre­
sentation of the modified artwork to be a bit mapped rep­
resentation. To assure accurate formations of the intercon­
nects, a feedback alignment system (42,44,46,48) is used to accurately 
position the laser beam throughout its raster scan.

Title: Process for waste water purification with batch feed to the activated sludge tank
IPC: C02F3/30
Filed: 1988-03-23
Abstract: In an aerobic process for waste water (effluent) purification with intermittent batch feed of the waste water to the activated sludge tank from which the treated waste water is discharged continuously, the nitrate content of the waste water is simultaneously reduced by the aeration of the activated sludge tank, commencing with the flow of the waste water to the tank, being restricted to values corresponding to </= 0.5 mg/1 of dissolved oxygen, or in particular turned off, until the nitrate content in the tank has fallen below 5 mg/1 or, in particular, below l mg/1. In such treatment of communal waste waters, an approximately 1 hour cycle time is advantageous and the aeration, commencing with the rapid input of the waste water charge, is turned off for about 5 minutes. Suitable feed batches are </= 30% and, in particular, between about 5 and 20% of the tank contents. In this process, the nitrate content is reduced during the phase with oxygen restriction, while in the subsequent phase (over longer periods of time), the ammonium carried in with the waste water feed is converted into nitrate, it being advantageous to provide for an adequate nitric bacteria population in the tank.

IPC: H01L29/267
Filed: 1988-05-18
Abstract: An insulating gate field effect transistor (IGFET) having 
a gate insulating layer comprising a single crystalline 
silicon carbide (SiC) film (2) epitaxially grown on a 
surface of a single crystalline silicon substrate (1) 
by a vapor phase epitaxial growth method. Using a single 
crystalline SiC film (2) as the gate insulating layer, 
the thickness and size of the gate insulating layer can 
be reduced, compared with those having SiO₂ amorphous 
film, because of its high dielectric constant and high 
breakdown voltage. So, compared with the MOS FET having 
an SiO₂ gate insulating layer of the same thickness and 
the same size, the invented IGFET can be made as large 
as twice in transconductance. Or if the same channel 
current is required, the size of the invented IGFET can 
be made as small as one half of that of the MOS FET. 
This enables the invented IGFET to operate at a high 
speed as much as twice of that of the MOS FET having 
SiO₂ gate insulating layer.

Title: Radial die-rolling machine
IPC: B21H1/06
Filed: 1989-09-19
Abstract: The invention relates to a radial die-rolling machine in which the roll groove is formed by a radially acting die ring on the outside, a radially acting, fixed and non-displaceable arbor roll entering the workpiece from below, an axially acting arbor-roll plate which closes off the roll groove from below and an axially acting bevel roll which defines the roll groove from above and swings away radially and axially. The rolling plane is inclined. The loading and unloading is considerably facilitated. Since rolling plane, rolling slide guide, groove mounting and feed cylinder lie in one plane, optimum radial die rigidity results. Since the workpiece ejector and the arbor-roll mounting are arranged on one side, namely below the workpiece, the arbor roll can be constructed to be fixed and therefore need not be moved for loading and unloading. This likewise increases the rigidity in the roll groove and necessitates only one infeed axis. The distance between the fixed arbor roll and the receiving point for the workpiece blank is always the same. This permits unloading of the rolling machine by a simple swivelling mechanism. In addition, high annular parts (bushes) can be produced.

Patent EP-0329292-A3 (EP)
IPC: C01B3/38
Filed: 1989-01-25
Abstract: A single pressure process for the production of 
methanol wherein the make-gas is produced by steam reforming a 
hydrocarbon feedstock, in admixture with recycled purge gas from 
the synthesis loop, at such a pressure that the make-gas can be 
fed, without further compression, to the synthesis loop at a 
pressure no lower than the pressure at the inlet to said 
circulator. The reforming is effected by primary steam reforming 
followed by partial oxidation with oxygen and secondary 
reforming, without any bypass of the feedstock of the primary 
reforming stage, so as to give a make-gas of approximately 
stoichiometric composition for methanol synthesis. The primary 
reforming is effected at above 55 bar abs. over a catalyst 
disposed in tubes heated by passing the secondary reformed gas 
stream past the external surfaces of the reformer tubes in a 
direction counter-current to the flow of reactants undergoing 
primary reforming in said reformer tubes. In this way heat is 
transferred from said secondary reformed gas stream through the 
walls of said tubes to supply the endothermic heat of the steam 
reforming reaction.  
     In preferred forms of the process the steam is 
incorporated into the feed to the reformer by saturation and the 
excess of steam is removed from the reformed gas by direct 
contact with cold water: in this way a high pressure steam system 
recovering power from the reformed gas is not needed.

Title: Two wire coolant level sensor
IPC: G01F23/26
Filed: 1989-08-11
Abstract: A two wire circuit for indicating liquid level in an 
automobile utilizing an incandescent lamp to provide the alarm 
signal with the power required to energize the circuit being 
derived via the lamp whereby the lamp and the circuit are 
serially connected between the battery terminals. The alarm 
circuits are provided with an oscillator which performs the dual 
functions of providing the detection signal through the probe and 
the drive signal for the output transistor controlling the lamp. 
In a first embodiment, signal pulses from an oscillator provide 
signals to an output circuit as well as to the detection probe in 
the forth of pulses, those to the probe controlling a latch 
responsive to the output of Schmitt trigger. The Schmitt 
trigger output is determined by the status of the probe in 
response to the signal thereto from the oscillator. The delay 
and output circuits are simultaneously controlled by the same 
oscillator pulses and the output of the latch to control 
operation of a lamp. Sufficient current always travels through 
the lamp to provide power to the remainder of the circuit. In a 
second embodiment, the output circuit is an SCR which stays on 
once latched until power thereacross is removed. In addition, 
positive and negative feedback are provided from the output to 
the input of the operational amplifier, the positive feedback 
path being shunted to reference potential when the probe 
resistance is low to provide no output from the op amp and 
therefore maintain the SCR off. When the probe resistance 
increases, the positive feedback becomes dominant and causes an 
oscillation to appear from the op amp which turns on the SCR and 
therefore the lamp also turns on.
