Patent EP-0091234-A3 (EP)
IPC: G03F9/00
Filed: 1983-03-24
Abstract: An auto-focusing alignment and measurement system 
for use in precisely positioning a semiconductor substrate 
with respect to an integrated circuit mask is herein disclosed. 
This system includes a moveable convergent lens operable 
with another pair of convergent lenses for alternately 
focusing images of the mask and the substrate onto a 
photodiode array. The photodiode array serves as a focus 
detector and, together with associated signal processing 
circuitry, provides a feedback signal for controlling displace­
ment of the moveable lens to equal the separation between 
the mask and the substrate with an accuracy better than the 
depth of field of the optics. An illumination source and 
viewing optics provide a magnified view of images of both 
the mask and the substrate superimposed and in focus, 
thereby facilitating alignment of the substrate with respect to 
the mask prior to photolithographic printing. This apparatus 
may also be employed to measure the degree of surface 
flatness and parallelism between the mask and the substrate.

IPC: B01D59/18
Filed: 1983-01-27
Abstract: A process for the separation of solid and/or liquid particles from gases or solids from liquids, as well as for the separation of gases or liquids with different densities is proposed, in which a Venturi tube is used. The gas and/or liquid mixture is introduced inwards in radially symmetrical manner from the outside through the slot of an annular nozzle at a high flow velocity which, in the case of gases, extends up to the velocity of sound. The gas is subject to the action of a high centrifugal acceleration in the slot, which has a radius of curvature of approximately 1 to 100 mm.

Title: Process for hardening shaped bodies of binder-containing building material, and autoclave for carrying out the process
IPC: B01J3/04
Filed: 1984-07-17
Abstract: The method relates to the hardening of form substances made of building materials and containing binding agents in a pressure chamber of an autoclave to which is conveyed a gaseous heating medium, the temperature of which is increased during a heating-up phase up to a given upper limit value. During a holding phase, the temperature is maintained at least until a given equalization temperature is reached on the inside of the form substances. Subsequently, during a cooling-down phase, the temperature is reduced by reducing the pressure to the expulsion temperature. Porous light building materials in a conventional process would absorb a high amount of water through the condensation of water resulting from steam having been conveyed into the autoclave for the purpose of hardening. However, in order to produce form substances of a low water content economically, according to the present invention, on the one hand, steam is replaced by gas which is maintained below the evaporation temperature of water through sufficient increase in pressure, and, on the other hand, as a replacement or complement, heat is conveyed to the inside of the pressure chamber before the cooling-down phase and an increase in the temperature of the steam beyond the given limit value is prevented by blowing off steam, thereby attaining an integrated drying process.

Filed: 1985-01-24
Abstract: In a system for recording and reproducing digital signals on a magnetic tape (2) by using a rotary head (1A, 1B), in which signals are recorded as a series of oblique tracks (5A. 5B) without guard bands, a pilot signal (P) that controls tracking alignment of a playback head (1 A, 1B) is recorded at a particular position in a specific pilot signal record region, independent from the information signal record region. The pilot signal (P) is arranged at first predetermined positions separated from the ends of the oblique tracks (5A, 5B) in the pilot signal record region on every other one of the oblique tracks (5A. 5B) and at second predetermined positions separated from the ends of the oblique tracks (5A, 5B) in the pilot signal record region on the alternate ones of the oblique tracks (5A, 5B). An erase signal (E) can also be recorded in the pilot signal record region such that a start position of the erase signal (E) corresponds substantiallyto a centre portion of the pilot signal (P) on the adjacent oblique track (5A, 5B). When the recorded oblique tracks (5A. 5B) are reproduced by a rotary playback head (1A. 1B) having a tracking width greater than the track width, the pilot signal (P) from the adjacent oblique tracks (5A. 58) will be detected and compared in level, and the comparison output used to control the tracking alignment of the rotary playback head (1A. 1B).

Abstract: In a process involving the successive formation of a soft 
magnetic film substantially consisting of Fe and Ni and a 
perpendicular magnetic film on a plastic substrate, the soft 
magnetic film is vacuum-deposited while its formation 
position is irradiated with an ion-beam so as to prevent 
cracks and lessen coercive force.  
     Apparatus for carrying out the deposition of the soft 
magnetic film includes a vacuum chamber (8) divided by a 
partition (7) into an upper chamber (9) and a lower chamber 
(10) which can be exhausted through outlets (11) and (12). 
The film substrate strip (6) is fed from a roll (1) round a 
cooled drum (3) to a winder (5). An evaporator (16) contains 
an iron-nickel ingot (15), and ion-beam radiation issues from 
the source (17). A screen (13) has an aperture (14) which 
limits the incident angle of the ion-beam onto the position of 
the substrate (6) passing round the drum (3).

Filed: 1986-07-16
Abstract: The present invention discloses a semiconductor strain 
gauge (7b) which is formed from a thin layer of semiconductor 
substrate (1) by means of an insulating layer (6,7a).  
     The invention also discloses a method of manufacturing 
such a strain gauge utilising silicon as the semiconductor 
material. The method employs laser recrystallisation technol­
ogy to recrystallise a thin layer of polycrystalline silicon (7) 
formed over an insulating layer (6) on a silicon substrate (1), in 
order to produce a thin layer of monocrystalline silicon (7b) 
isolated from the subsrate. This is utilised as a strain gauge.  
     The advantages of the strain gauges in accordance with 
the invention include the fact that they can be operated over a 
wide temperature range, as there is no diode junction formed 
between the gauge and substrate. They can thus be used in 
many situations were semiconductor strain gauges have not 
before been useful.

Filed: 1986-09-10
Abstract: A self-centering steady rest according to the invention 
intended to improve the present technical ability of a steady 
rest to center a round workpiece with greater accuracy. This 
is achieved by virtue of the fact that the steady rest has three 
gripper pivot arms with support rollers, said pivot arms 
having the same bending stiffness regardless of its gripping 
force and that one of the pivot arms has an extended opening 
movement so that the workpieces of approximately the max­
imum gripping diameter can be easily inserted and removed 
from the steady rest with the bridge loader. Moreover, the 
gripping force of the pivot arms can be adapted to the value 
required to make the workpiece center and thus the life of the 
support rollers can be appreciably increased.
