Title: Mask imaging on semiconductor wafer - uses mask coordinate support grid whose strip width corresponds to half grid constants
Inventor: SCHUSTER-WOLDAN HANS DR
IPC: H01L21/027
Filed: 1977-06-20
Abstract: The imaging uses an electron-optical technique and a mask with a support grid which carries partial surfaces opaque to the electron beam, forming the surface pattern. The mask image on the wafer is shifted in two coordinate directions at right angles or parallel to the grid structure. The support grid of the mask is formed by coordinate strips whose width is so rated as to correspond to a half of the grid constants. The opaque surfaces of the pattern are provided on the grid in such a manner that their edges abut the corresponding edges of the strips. An aperture of the grid, image on the wafer is subsequently shifted in each of the four corner points of the image aperture, in order to shift the image of the surface centre point. A light exposure follows each of the four image shifts.

Title: Insulation for nuclear reactors - comprising panels of metal sheets enclosing air, with deformable edges preventing convection but allowing thermal expansion
Inventor: FRICKER PETER
IPC: G21C11/08
Filed: 1977-06-30
Abstract: An insulation partic. for a nuclear reactor, between the outer periphery of the reactor pressure vessel and the inner periphery of the concrete biological shield, consists of rectangular metal sheets with separators between them, enclosing air; the edges of the sheets are folded into a V form giving the edges a dimensional elasticity. When the panels are pressed together the edges are deformed over a distance determined by the separators and the sheets form panels which are fluid tight and in which convection cannot take place. The arrangement provides an insulation in which convection is effectively prevented in and between the panels but such that the different panels form in the packed state a standardised element which can be made economically and installed easily. The element has the necessary rigidity and constant dimensions but in spite of its fluid-tightness in its marginal zone, the different sheets can expand freely in length and width without thermal strain. Marginal bands on each panel are not necessary.

Title: Interference components elimination in thermal camera video signal - involves periodically interrupting thermal flow and signal is delayed and further processed
Inventor: HEITMANN JUERGEN DIPL ING
IPC: H04N5/33
Filed: 1978-10-02
Abstract: A thermal flow is alternately blocked and passed to the heat sensitive layer by a rotating diaphragm. This layer is scanned in a raster in order to generate the video signal, with the video signal polarity reversed synchronously with the rotating diaphragm. The video signal is delayed by the duration of the blocked or free period of the thermal flow. The delayed signal is subtracted from the non-delayed signal, and the difference signal (c) is subtracted in a subtraction stage (6) from the non-delayed video signal (b) in order to obtain a signal free from interferences.

Title: Stepping-motor of sync. type reluctance motor - uses U=shaped cross=section capacitors with limbs facing one another to form gap and supplied with pulsed alternating polarity voltage
IPC: H02N1/00
Filed: 1978-12-05
Abstract: For use as a stepping-motor or as a sync. motor, the reluctance motor has a rotor similar to a gearwheel where the ferromagnetic tooth is drawn through the centre of a magnetic field in the air-gap between the limbs of one or more electromagnets. To enable the motor to be used as a synchronous motor at higher powers than hitherto, and to avoid the protracted inertia (delays) at each reversal of the magnetic field direction, or the manifestation of remanance, heat losses etc., two capacitors (7, 8) of U-shaped cross-section are arranged so that their limbs are facing one another to form a gap (15, 16, 17, 18) between them. Teeth (3, 3') made from a material having greater density than that used for the gear wheel(s) (1, 2) protrude into the gap between the capacitors, and the axis of rotation (4) of the gear wheel being parallel to the capacitor(s) limbs. Alternating polarity voltage pulses are fed to the capacitors, with adjacent capacitors having opposed polarity (7 and 8) and (13 and 14).
