Patent EP-0541160-A1 (EP)
Inventor: ZIJLSTRA PIEBE ANNE
IPC: H01L21/3065
Filed: 1992-10-29
Abstract: A method of manufacturing a semiconductor device whereby an insulating layer (3) comprising silicon nitride is deposited on a surface (1) of a slice of semiconductor material (2), in which layer contact windows (8) are then provided in that the layer is locally covered with a layer of photoresist (5) and subsequently uncovered portions thereof are removed in two etching steps which are each carried out in a plasma containing fluorine and generated in a reaction chamber (20,21), so that the insulating layer (3) is etched away isotropically over part of its thickness during the first etching step and then anisotropically over its remaining thickness during the second etching step. The two etching steps are carried out in plasmas generated in gases containing less than 10 vol.% oxygen. It is achieved by this that the contact holes (8) in the layer (3) comprising silicon nitride can be so etched that they are practically identical seen over the surface of the entire slice and also from slice to slice.

Abstract: A solid-state imaging apparatus comprising a solid-state image sensor which is rotatable around an axis is provided. Adjusting the optical axis at right angles to the solid-state image sensor, aligning the optical axis with the rotational axis and centring the optical axis at the centre of the solid-state image sensor are performed employing adjustment members having a convex spherical contact face and a concave spherical support face. Employing such adjustment means is particularly advantageous when used in conjunction with a solid-state image sensor because such adjustment members are particularly effective in making a light-light construction and in discharging heat from the solid-state image sensor.

Abstract: In the heat treatment of food particularly pre-packed food it is important to control the temperature and to provide uniform heat distribution within the article. By using a number of microwave emission slots (13) in a waveguide (6) which are brought to resonance in the presence of pre-packed articles (12) carried over the slots by a conveyor (14) the rate of rise of temperature within the article is controlled without unnecessary energy loss between articles carried seriatim on the conveyor (14). The slots (13) may be set obliquely to the direction of passage of the article (12). Alternatively the slots may be formed by a series of smaller slots staggered obliquely across the waveguide (6) so that the presence of the article (12) tunes each of the slots in turn as it passes over the waveguide. The slots may be covered with low-loss dielectric material to prevent extraneous matter falling into the slots and to space the article from the slots so as to control power dissipated.

Abstract: A birthing bed (10) has a base (11), an intermediate frame (15) mounted on the base (11) with a power-actuated linkage (16) to raise and lower the intermediate frame (15) with respect to the base (11). A main frame (18) is pivotably mounted on the intermediate frame (15) so that it can be shifted from a horizontal position to an inclined Trendelenburg position. The intermediate frame (18) is adapted to be lowered to bring the patient support surface to a very low level. In that level, the bed (10) can be shifted to a Trendelenburg position with limit switches (95) causing the intermediate frame (15) to rise in order to accommodate the shift of the main frame (18) to the inclined Trendelenburg position.

Abstract: The invention relates to a method and an arrangement for reducing the driving power for a hydraulic elevator in which an energy-saving drive is realised by an advantageous combination of various devices. The elevator car (1) is suspended in the shaft (7) with a rope deflection known per se in the ratio of 4:2 and is connected to a hydraulic piston/cylinder unit (10). A counterweight system in the ratio of 2:1 is arranged at the head end (16) of the piston/cylinder unit (10) so that the requisite pressure force at the piston can be reduced. The counterweight (23) is designed in such a way that the weight of the car and the load expected to occur most frequently in the car are balanced. The cylinder (11) of the piston/cylinder unit (10) is acted upon by the pump for both the ascending travel and the descending travel of the elevator car (1), in the course of which a differential circulation of the fluid flows takes place for the ascending travel, as a result of which a smaller fluid volume can be used for the dimensioning of the pump. <IMAGE>

Abstract: A forklift truck which is preferably operated by electrical battery has a drive component (1) and a liftable load component (5) which is connected to the drive component (1) by means of a four-bar linkage and, adjacent to the drive component (1), an end wall (11) which is perpendicular with respect to the longitudinal axis of the vehicle and lies opposite an edge (14) which is parallel thereto and is formed on a wall (13) of the drive component (1) in its upper region. The end wall (11), formed on a battery holding device (8), of the load component (5) is, viewed in section parallel to the longitudinal axis of the vehicle, curved convexly in the region of the edge (14) of the drive component (1) towards the drive component (1) in such a way that when the load component (5) is lifted and lowered an essentially uniform distance remains between the edge (14) of the drive component (1) and the end wall (11) of the load component (1). As a result, the change in distance, produced when lifting the load component (5), between the end wall (11) of the load component (5) and the drive component (5) is compensated in the area of the edge (14) which is dangerous in terms of safety technology by the shape of the end wall. Any risk of injury to the operator which arises in conventional forklift trucks from unintentional trapping of the fingers is eliminated at this point. The convex curvature corresponds to a circular-arc-shaped section (15) whose radius (R) is the same as the radius (R) of the circular-arc-shaped section over which in each case the movable ends (9b, 10b) of the four-bar linkage move. <IMAGE>
