Patent EP-0171880-A3 (EP)
Title: Energy economizer controlled-current start and protection for induction motors
IPC: H02P1/28
Filed: 1985-05-28
Abstract: A standard, unmodified induction motor (11) starts with reduced input current, energy consumption and mechanical stress and is further protected from AC power source "phase loss", excessively low or high voltage or a locked-rotor condition during start-up or any subsequent moment while running when its stator winding (13,14,15) is energized from a sine wave source (300) thrkough a signal-responsive wave modifier EET-IC operative to control the portion of each cycle of the sine wave which is coupled from said source to the stator winding. A stator current sampling arrangement (6, 7, 8), and a motor current demodulator responsive to the first few hundred microseconds of stator winding initial inrush current each time said current increases from zero cooperate under certain conditions to produce signals for controlling associated wave modifier means, thereby to achieve a preferred magnitude of motor starting current under rated load conditions and achieve near-optimum motor operating efficiency during start-up and subsequent running with reduced loads and associated motor protection means (4) which inhibits said wave modifier means thereby to de- energise said stator winding under locked-rotor conditions that occur when motor start-up is attempted or later when the motor is running, or an AC power source anomaly occurs which would otherwise cause start-up stalling, excessive motor running current or motor stalling under rated loads.

Title: Automatic tracking apparatus.
Inventor: SAKAMOTO HITOSHI
IPC: G11B5/592
Filed: 1985-09-25
Abstract: An automatic tracking apparatus for use in a video tape recorder including a magnetic head mounted on a piezo-electric element. The automatic tracking apparatus includes a driving pulse generator which generates a driving pulse signal causing the piezo-electric element to drive the magnetic head. The driving pulse signal has a waveform including a lumping portion causing the magnetic head to jump from one recording track to another recording track, which generates ringing vibrations in the piezo-electric element in a change-speed reproduction mode. An inflection point is imposed on the jumping portion of the driving pulse signal waveform. The position of the inflection point is determined in accordance with the amplitude level of the ringing vibrations so as to minimize the amplitude level of the ringing vibrations.

24 powering the spiked sheet.
Patent EP-0217570-A3 (EP)
IPC: H04L27/22
Filed: 1986-09-10
Abstract: Error multiplication in a V.22 bis modem is avoided by 
using forward error correction and single symbol coding in­
stead of differential coding. In the receiver section (25b) the 
error syndrome bit of the error corrector (32) is used in es­
tablishing phase and timing synchronization by causing the 
symbol detector (26) of the receiver (25b) to try all possible 
combinations of phase and timing, and to lock onto the com­
bination which produces a minimum of error syndrome bits. 
The descrambler (30) receives the error-free corrected bit 
stream.

Patent EP-0229017-A3 (EP)
IPC: A61M5/178
Filed: 1987-01-06
Abstract: In an injection syringe for use once only the piston rod 
(4) is connected to the piston (3) by claws (9) which 
upon pressing of the piston rod (4) against the piston 
(3) during injection break or become deformed to such an 
extent that it is no longer possible to retract the 
piston (3) for the purpose of refilling the syringe. The 
deformation is effected by means of a conical portion 
(l3) on the piston, said portion by wedge effect pressing 
the claws (9) radially outwardly when the piston rod (4) 
is pressed against the piston (3). The rigidity and 
strength of the claws (9) is adapted to the resistance 
experienced during injection of a liquid so that the 
claws will certainly be broken or otherwise brought out 
of engagement with the piston (ll). On the other hand 
the force tequired to push the piston forward in an empty 
syringe does not have to be sufficient to break the claws 
(9).

Title: Integrated semiconductor circuit with at least two planes made of aluminium or aluminium compound and method of manufacturing the same
IPC: H01L23/532
Filed: 1987-11-25
Abstract: To improve the planarisation and the reliability of low-resistance conductor tracks, tungsten is used as via filler (6, 16) and metal silicides as interlayers (5, 9, 19) in the multilayer interconnection of integrated semiconductor circuits having at least two metallisation levels (8, 18) consisting of aluminium or an aluminium compound. The metallisation system according to the invention contains a nucleation layer (7, 17) preferably consisting of titanium/titanium nitride as lower layer for each metallisation level (8, 18), the resistance of the aluminium layers (8, 18) to electromigration thereby being increased, and a layer (9, 19) preferably consisting of molybdenum silicide as top layer for each metallisation level (8, 18), the low resistance of the metallisation (8, 18) thereby being improved. In addition, the sandwich-type metallisation structure improves the planarity and the thermal stability of the circuit. Since the number of metallisation layers (8, 18, 28) is optional, the invention can be used for VLSI circuits.

(10). The trench (26) is filled with a conductive 
material which is in electrical contact with the substrate 
(10). A top surface contact electrode (74) is formed over 
the trench, in contact therewith, thereby also contacting 
the underlying substrate (10). For very narrow trenches, 
semiconductor areas (68, 70) are formed adjacent the top 
of the trench to thereby provide additional contact 
surface for the electrode (74).
Patent EP-0273281-A3 (EP)
Title: Work roll for a rolling mill made by compound casting
IPC: C22C37/08
Filed: 1987-12-12
Abstract: The core of the work roll consists of an iron alloy, and the shell of the roll consists of an iron alloy having the following constituents in % by weight: C = 2 - 3.5, Cr = 10 - 25, Mo less than 5, Ni less than 2, Mn less than 2 and Si less than 1. These known work rolls have the disadvantage that they cannot be used universally in spite of a comparatively high wear resistance, for example not in the first stands of a finishing step for special sheet grades and of hot-rolled strip lines. To eliminate these disadvantages, the Ni content of the iron alloy of the shell is increased to 4 - 6 % by weight. In other respects, the usual composition of high-chromium rolls is maintained. As a result of this effect on the metal structure matrix, the disadvantageous properties of the known work rolls are eliminated, with unchanged carbide structure. Surface hardnesses between 60 and 100 ShC can be achieved.
