Patent EP-0278290-A3 (EP)
Title: Submicron dimension compound senmiconductor fabrication
IPC: H01L21/306
Filed: 1988-01-22
Abstract: Submicron structure fabrication is accomplished by 
providing vapor chemical erosion of a compound crystal 
by suppressing the more volatile elements so that the 
less volatile element is provided with an anti-­
agglomeration and erosion rate limiting capability 
which can be followed by subsequent regrowth in the 
same environment. The erosion is sensitive to crystallo­
graphic orientation.

im Magnetfeld ausgerichteten Teilchen in ihrer Lage fixiert 
werden.

Abstract: Bei üblichen Mikrowellengeräten dieser Art sind 
durch manuell zu betätigende Haltevorrichtungen für 
den Beutel die Bedienung umständlich und eine innige 
Durchmischung des Beutelinhalts gefährdet, weil der 
Zirkulation des Beutelinhalts Strömungshindernisse 
entgegenstehen. Das neue Mikrowellengerät (1) soll 
unabhängig von der Beutelgröße bedienungsfreundlich 
sein und eine innige Mischung des Beutelinhalts 
gewährleisten.  
     Aus diesem Grund weist die Aufnahmevorrichtung (7) 
eine oben offene, flache Schale (8) mit einem 
umlaufenden Stützrand (10) auf, in der der Beutel 
(2) mit freibleibender Oberseite (6) allein durch 
den Stützrand (10) lagesicherbar ist. Mit der 
offenen Schale (8) ist eine einfache Bedienung 
gegeben. Durch die freibleibende Oberseite (6) 
stellt sich eine permanente wirkungsvolle 
Volumensverlagerung ein, die zu einer innigen 
Mischung des Beutelinhalts (5) führt.  
     Das Mikrowellengerät (1) eignet sich aufgrund des 
hohen Bedienungskomforts und der guten Qualität des 
erwärmten Beutelinhalts sowohl für wissenschaftliche 
als auch für ambulante Anwendungsfälle.

Title: Process for optimizing head position to overcome disk misclamping and imperfections
IPC: G11B21/10
Filed: 1988-12-21
Abstract: A process allows a disk drive system to 
optimize head position in order to minimize the 
effects of track variations due to disk misclamping 
and imperfections. The process utilizes a transducer 
head having a width less than a track width. The 
small size of the transducer head allows it to be 
positioned within a stationary band which remains 
within the boundaries of the track for the complete 
revolution of the disk. Once the head is positioned 
within this band for one track of the disk, this track 
can be used as a reference for positioning the head 
within the bands of the other tracks.

Title: Profiling machine
IPC: B21D5/08
Filed: 1989-10-17
Abstract: A rolling mill wherein the frame or frames for pairs of superimposed rolling tools can be lifted off the base by a crane. Each rolling tool carries a first clutch element receiving torque from a separable discrete second clutch element on a support which is adjacent a properly installed frame. The support is mounted on a reciprocable carriage, together with or independently of a drive for the second clutch elements, and can be moved in the axial direction of the tools toward and away from the adjacent frame. The upper second clutch element of the pair of second clutch elements on the support is movable up and down by a fluid-operated motor toward and away from a position of alignment with the corresponding first clutch element. The second clutch elements have pins which enter registering sockets in the adjacent first clutch elements, or vice versa, and the second clutch elements are axially movably mounted in their bearings on the support and are biased toward the respective first clutch elements. The second clutch elements are disengaged from the respective first clutch elements by moving the support away from the adjacent frame. A sensor cooperates with a stop to ensure that each movable second clutch element moves to a position of accurate alignment with the respective first clutch element, and the carriage can be moved toward the frame only when the alignment of the movable second clutch element with the respective first element is completed.

Title: High-definition television channel with time and frequency multiplexing
IPC: H04N9/797
Filed: 1989-08-29
Abstract: In a high definition television system, line 
differential panel signals LDR and LDL, panel signals PL and PA 
and luminance signals Yh are time expanded. The time 
expanded line differential panel signals are quadrature 
modulated to each other, as are the panel signals, the 
quadrature modulations all lying in a common frequency 
band. The luminance signals are converted to the same 
frequency band and the resulting signals are time 
multiplexed with the above-mentioned quadrature modulated 
signals. The time multiplexed signal is then frequency 
multiplexed with DSS signals which have been frequency 
converted to a frequency band contiguous with the common 
frequency band. The center portions LDC of the line 
differential signals are quadrature modulated onto the 
same carrier FC as the standard television signal.

therefrom, enabling removal of bags in one-handed 
operation. The tack securing of each following bag is 
provided by the application of an adhesive (36) to the 
inner face panel of each bag adjacent the mouth end 
thereof as the roll is being formed.

Title: Attraction type magnetic levitating apparatus
IPC: B65G54/02
Filed: 1989-03-30
Abstract: A plurality of stators (16) of a linear induction 
motor are arranged at predetermined intervals, and guide 
rails (12a, 12b) are mounted on an upper portion of a 
track frame (11) having a U-shaped section. A levitated 
object (15) is magnetically levitated below the track 
frame (11) so as to freely travel along the guide rails 
(12a, 12b). Magnetic support units (31a, 31b, 31c, 
31d) having electromagnets (55) for obtaining a levi­
tating force, optical gap sensors (34a, 34b, 34c, 34d) 
for detecting gap lengths between the support units 
(31a ∼ 31d) and the guide rails (12a, 12b), i.e., 
deviations in a levitating direction, and optical gap 
sensors (46a, 46b, 46c, 46d) for detecting deviations in 
a guiding direction perpendicular to a traveling direc­
tion of the levitated (15) object are respectively 
arranged on the four corners of the upper surface of the 
levitated object (15). The length of each magnetic sup­
port unit (31a ∼ 31d) is larger than the width of each 
guide rail (12a, 12b). Each magnetic support unit (15) 
is disposed such that the inner ends of the unit (15) 
and the guide rail (12a, 12b) are aligned, and the outer 
end of the unit (15) extends outward from that of the 
guide rail (12a, 12b). A deviation between an output 
from each optical gap sensor (34a ∼ 34d, 46a ∼ 46d) and 
a corresponding reference value is fed back to a corre­
sponding magnetic support unit (15), thereby controlling 
each electromagnet (55).

Title: Page printer
IPC: G06F13/34
Filed: 1989-04-27
Abstract: A page printer with an internal CPU (15), 
interrupt controller (9), and direct memory access 
controller (DMAC) (18) has a direct memory access (DMA) 
stopping circuit (18a) in the DMAC, the function of 
which is to stop DMA transfer in response to a DMA stop 
signal and restart it in response to a DMA restart 
signal. The DMA stop signal is generated by the 
interrupt controller (9) when it selects certain 
interrupt requests, such as communication interrupt 
requests, enabling the CPU (15) to service these 
requests promptly. The DMA restart signal is 
generated at the end of the interrupt service routine. 
This arrangement permits DMA transfers to be performed 
in burst mode, stopping only when urgent interrupt 
service is required. Burst-mode DMA improves the 
speed of operation of the printer.

Abstract: Beschrieben wird ein Verfahren und eine Vorrichtung zur 
Erzeugung von Ionenstrahlen mit großflächigem Strahlquer­
schnitt. Ein Ionenstrahl, der zur Trockenätzung bei der 
Herstellung mikroelektronischer Bauelemente verwendet wird, 
muß eine hohe Strahlqualität aufweisen (kleine Divergenz, 
wenig Verunreinigungen, hohe Stromdichte).  
     Bei bekannten großflächigen Ionenstrahlquellen werden die 
Ionen mit Hilfe von Gittern aus dem Plasma extrahiert. Die 
Verwendung des Gitters wirkt sich wegen des Feldverlaufes 
an den Gitterpunkten störend auf die Strahlqualität aus.  
     Das erfindungsgemäße Verfahren kommt völlig ohne Gitter 
aus, die Ionen werden mit Hilfe von Metallzylindern (5) be­
schleunigt. Dabei gewährleistet eine gepulste Erzeugung der 
Ionen und eine gepulste Beschleunigung, daß die Ionen nur 
dann durch Felder beschleunigt werden, wenn sie sich in 
Bereichen bewegen, in denen ein nahezu homogenes Feld 
herrscht. Durch die damit erreichte hohe Strahlqualität 
eignet sich der Ionenstrahl zur Herstellung kleinster 
Strukturen im Sub-µ-Bereich.
