Patent EP-0199696-A3 (EP)
IPC: B04B5/04
Filed: 1986-04-21
Abstract: The present invention briefly concerns a centrifugal 
rotor for laboratory centrifuges, comprising a disk (1) and a 
cover (10), whereby a ring-shaped carrier (5) of capillary 
tubes (9) is attached to the bottom of the disk (1). The disk (1) 
has at its outer periphery an axially projecting flange (3) 
which is inclined relative to the axis of rotation of the 
centrifugal rotor, so that any liquid escaping out into the 
centrifugal rotor is urged by the centrifugal force to the 
ring-shaped, circular edge (20) formed between the flange (3) 
and the bottom (2, 17) of the disk (1). Preferably, the cover 
has a peripherally outer portion with a step in the form of an 
axially extended portion (13), which continues in a radially 
ring-shaped edge portion (14), the axially extended portion 
(13) having a height greater than the thickness of the 
folded-back portion (4) of the axially projecting flange of the 
disk (1) and a gasket ring positioned thereon.

Patent EP-0271711-A3 (EP)
IPC: C21B5/04
Filed: 1987-11-10
Abstract: Die Herstellung von Roheisen im Hochofen aus reinem 
Olivin-Pelletmöller, also einem Möller mit einem hohen 
MgO-Gehalt, hat den Nachteil, daß diese Pellets nur be­
grenzt verfügbar sind. Um auch dann noch mit einer ge­
ringen Schlackenmenge von nur etwa 160 bis 180 kg/t RE 
auszukommen, wenn nicht nur Pellets mit diesem hohen 
MgO-Gehalt eingesetzt werden, besteht nur ein Teil des 
Möllers aus Fe-reichen Pellets mit einem hohen MgO-Gehalt, 
diesem Mölleranteil wird ein weiterer Mölleranteil mit 
einem niedrigem MgO-Gehalt hinzugefügt und der dritte 
Möllernateil dann so zusammengesetzt, daß eine Hochofen­
schlacke mit einem MgO-Gehalt von mehr als 10 % anfällt. 
Wegen der geringeren Schlackenmengen kann dann auch die 
Koksmenge wesentlich reduziert werden, und infolge der 
Verringerung des MgO-Gehaltes der Hochofenschlacke ist 
die Verwendungsmöglichkeit dieser Schlacke für die Zement­
herstellung erheblich verbessert.

Title: Method of spin-welding
IPC: B29L23/00
Filed: 1987-02-25
Abstract: An end component (3) is spin-welded into the cut end of an 
extruded tube (1) with the application of axial pressure but without the 
application of radial pressure to the weld area. The radial forces 
required to create a weld are provided by hoop stresses which are 
formed in the tube by shock-cooling the tube as it emerges from the 
extrusion die. When the tube is cut, the hoop stresses cause the cut 
end of the tube to contract radially prior to insertion of the end 
component. To assist in insertion of the end component, a cylindrical 
skirt thereof (4) is provided with a chamfered end (9).

Patent EP-0233823-A3 (EP)
IPC: H01L21/3065
Filed: 1987-02-17
Abstract: With an increase of integration density in an integrated 
circuit, the channel length of MIS FET becomes shorter and 
shorter, which causes a hot carrier effect. To solve this prob­
lem, the doping profile of source/drain regions and doping 
amount must be precisely controlled such that a strong elec­
tric field is not generated in a transition region from channel 
to drain. To obtain this result reflowed sidewalls (14B) of 
doped silicate glass having a gentle slope are formed on both 
sides of a gate electrode (13A), and the gate electrode and the 
sidewalls thus formed are used as a mask for ion implanta­
tion. The depth of ion implantation and the doping amount 
change gradually from the channel region to the drain region 
avoiding the generation of a strong electric field and thus 
alleviates the hot carrier effect. The present invention has 
also an effect of obtaining a passivation layer having a gentle 
slop on the surface and avoiding broken wire troubles in an 
aluminium wiring layer formed thereabove.

Abstract: A block diagram editor system and method is 
implemented in a computer workstation that includes a 
CRT and a mouse, graphics and windowing software, and 
an external communications interface for test 
instruments. The computer is programmed for 
constructing, interconnecting and displaying block 
diagrams of functional elements on the CRT. From 
prestored routines for each functional element, the 
softwave assembles and executes a program that emulates 
the functional operations of each element and transfers 
data from output from each element in turn to an input 
of a succeeding block, as determined by the block 
diagram configuration. The block functions include 
signal generating and analysis functions, and functions 
for control of various types of test instruments, which 
can be interactively controlled through the CRT and 
mouse. The computer converts desired outputs of the 
instruments into control settings and receives, 
analyzes and displays data from the instruments. 
Blocks can also be grouped into macroblocks.
