Patent EP-0256298-A2 (EP)
Inventor: KNOEDLER CHRISTINA MARIE
IPC: H01L29/812
Filed: 1987-07-10
Abstract: A process for the fabrication of a vertically differentiated semiconductor structure is disclosed. In this process the semiconductor structure is covered with a vertical erosion control mask (13, Fig. 3). The control mask covering at least one horizontal surface (7) of the semiconductor structure is removed leaving the vertical surface covering (13) intact (Fig. 5). An isotropic etching of the uncovered horizontal surface (7) next occurs. Finally, the control mask covering (13) of the vertical surface (11) of the semiconductor structure is removed (Fig. 1). This process permits etching treatment of horizontal surface defects without adverse effect on the vertical surface (11) of the semiconductor structure.

Abstract: The control apparatus is provided, in particular, for controlling the output of the drive motor of a vacuum cleaner. It contains a circular disc (1) having a control axle (2) which engages in a potentiometer which is adjustable by means of the rotary movement of the control axle (2). Moulded onto the outside circumference of the disc (1) is a flexible, but relatively rigid guide strip (3), the free end of which is provided with a slide element (4). The slide element (4) can be moved along a straight guide portion, the guide strip (3) being arranged between lateral guides. When the slide element (4) is moved in the direction of the disc (1), the guide strip (3) rotates the disc (1) and is thereby wound onto its circumference whereas, with displacement of the slide element (3) in the opposite direction, it is unwound from the circumference of the disc (1) again. The control apparatus requires little space and operates reliably even over a long duration of use (Figure 1). <IMAGE>

Abstract: Dilatation procedures and catheter instrument for treating patients having acquired aortic stenosis, typically in which there are calcific deposits on the leaflets of the aortic valve. A dilatation balloon introduced into the stenosed aortic valve via the aorta while the blood circulation of the patient is maintained by the heart via the aortic valve, is inflated to grossly deflect the leaflets of the valve in a manner avoiding blocking the outer portions of the commissures of the valve. This inflating step enables substantial flow of blood through the outer portions of the commissures during systole despite the presence in the valve of the large inflated balloon. By prolonging the inflation for at least 30 seconds, over a large multiplicity of heart beats the calcific deposits are disturbed to increase the pliability of the leaflets and the degree of their opening, in an action found not to produce emboli. The catheter instrument incorporates means for measuring the pressure gradient across the valve and has features facilitating introduction, retention of position during inflation, withdrawal and re-crossing of the valve to achieve progressive enlargement of the aortic valve.

Abstract: A method of filling a cassette (34) with a length of magnetic tape (4) starts with the insertion of a cassette (34) into a holder (32). A length of leader tape (111) is withdrawn out of the cassette by an extraction member (67) positioned on a splicing table (68) and cutted into first and second leader tape parts. Said first leader tape part is spliced to a magnetic tape (4). A tape guide (81) is moved from a rest position free of contact with the tape (4) to an operating position for contacting the tape, said operating position being aligned with respect to said cassette (34) such that during the winding step said tape (4) after leaving said tape guide (81) is fed directly to a take-up hub (112) within the cassette, without coming into contact with other parts of the cassette (34). Winding is terminated after said magnetic tape (4) has been wound to a selected point, at which the tape is cutted, followed by splicing the magnetic tape (4) to said second leader tape part, winding said second leader tape part into the cassette (34), and discharging said cassette (34) from said holder (32).

Abstract: A television line output circuit comprises a first sawtooth network with a diode (D), a trace capacitor (Ct), a retrace capacitor (Cr) and a line deflection coil (Ly), and a second sawtooth network with a diode (Dʹ), a trace capacitor (Cʹt), a retrace capacitor (Cʹr) and a coil (Lʹ). The diodes (D, Dʹ) are connected in series and the two sawtooth networks connected across a line output transistor (Tr). A first modulation source (M1) is connected across the trace capacitor (Cʹt) in the second sawtooth network to modulate the line deflection current to overcome East-West pin-cushion distortion. 
     A resistor (R) of low ohmic value is connected between the anode of the diode (Dʹ) in the second sawtooth network and earth and a second modulation source (M2) is connected across this resistor (R). The second modulation source (M2) provides a signal dependent on beam current to correct for display errors at line frequency rate as they occur.

Abstract: In a gamma radiography apparatus a gamma scintillation camera 1 with a rectangular scintillation plate is suspended so as to be counterbalanced and rotatable about a horizontal axis 44 for single photon emission tomography, Figure 1b. To enable a total body emission radiography scan to be carried out by the same apparatus, Figure 2b, the head 1 must be turned through 90 degrees in plan view. 
     This is effected in a compact manner by using an intermediate carrier formed by at least one of the arms 7 and 8, pivoted about a first axis 9 relative to the carrier 12. The head 1 is pivoted in the arms 7, 8, about a second axis 19 at 45 degrees to the first. A rotation of 180 degrees about both axes turns the camera field through 90 degrees.
