Abstract: The adjustable spacer is used for the attachment of two plate-shaped components (18 and 25) at a variable spacing and consists essentially of a plastic anchoring part with a hollow shaft (14) having an internal thread, which anchoring part can be inserted into a mounting hole in the one component (18), and consists of a spacer screw which can be screwed into the shaft (14) and has a supporting head (3). …<??>In order to be able to screw the component (25) resting on the spacer screw onto the supporting head (3), after precisely adjusting the said spacer screw, without the screw rotating at the same time in the hollow shaft (14), the spacer screw has a multiply slotted, dowel-like expansion part, underneath the threaded shank (4), with a penetrating hole (5) in the threaded shank (4) and a narrowed penetrating hole, connecting thereto, in the expansion part for a woodscrew (13) to be screwed in. In addition provided on the external envelope of the dowel segments (8) formed by the longitudinal slots there are also ribs, running parallel to the axis, while the hollow shaft (14) of the anchoring part is provided underneath the internal thread with grooves running parallel to the axis into which the ribs engage in a positively locking manner when the dowel segments (8) are spread apart by the screw (13) being screwed in. …<IMAGE>…

Patent EP-0443111-A1 (EP)
Inventor: GRAF RUDOLF
IPC: F16B7/04
Filed: 1990-11-26
Abstract: The fastener (1) for attaching a column (3) to a tubular bar (5) has two jaws (7, 9) and a screw (11) with which the jaws (7, 9) are held in one end of the bar (5) diametrically opposite one another in the longitudinal direction of the bar. The jaws (7, 9) are movable with respect to one another. Each jaw (7, 9) has an end face (15a, 17a) which is intended for bearing against the column (3), is adapted to the latter and has a projecting extension (19a, 21a) claw-like or hook-like in cross-section. The cross-section of the extension (19a or 21a) of the one jaw (7 or 9) is designed in mirror image to the cross-section of the extension (21a or 19a) of the other jaw (9 or 7). In each case an extension (19a, 21a) of each jaw (7, 9) engages in one overhanging edge area of one of two grooves (35, 37) formed in the column (3). The fastener (1) according to the invention enables telescoping columns to be used, since the fasteners (1) do not protrude into the inner space of the column (3). Furthermore, in an assembly produced from columns (3) and bars (5) which are connected to one another by the fasteners (1) according to the invention, columns with two different diameters can be used without having to adapt the length of the bars (5). The annular grooves (35, 37) on the outside of the column (3) can be produced inexpensively in a turning operation which is simple to carry out. The bars (5) can be attached to the column (3) at almost any angle, which results in additional design possibilities in the manufacture of assemblies. <IMAGE>

Inventor: TSUNODA TETSUJIRO C O INTELLEC
IPC: H01L21/336
Filed: 1990-11-29
Abstract: A bipolar type semiconductor device includes a first semiconductor region (101) of a first conductivity type, a second semiconductor region (102) of a second conductivity type formed on the main surface of the first semiconductor region, a third semiconductor region (103) of the second conductivity type formed on the main surface of the second semiconductor region, a fourth semiconductor region (104) of the first conductivity type formed in at least part of the main surface area of the third semiconductor region (103), and a fifth semiconductor region (105) of the second conductivity type formed in at least part of the main surface area of the fourth semiconductor region (104). A low carrier-lifetime layer (110) having a peak of the number of recombination centers of carriers is formed in the second semiconductor region (102). The low carrier-lifetime layer (110) is formed by irradiating high-energy particles such as protons, particles, heavy hydrogen, or hydrogen molecule ions from the rear surface side of the first semiconductor region (101). In a case where the second semiconductor region (102) is not formed, the low carrier-lifetime layer (110) is formed in that part of the third semiconductor region (103) which lies near the junction between the first semiconductor region (101) and the first semiconductor region (103).

Abstract: The inventive method provides a silicon carbide membrane for X-ray lithography having high performance in respect of stability against high energy beam irradiation. The method comprises depositing a silicon carbide film by sputtering on a silicon wafer as the substrate under such conditions that the thus deposited film is under a tensile stress in a specified range by keeping the substrate at a temperature higher than 500 °C. The thus deposited silicon carbide film is at least partly crystalline and the crystallinity thereof can be defined by the sharpness of a peak in the X-ray diffraction diagram of the membrane which can be assigned to the (1 1 1) plane of the crystalline silicon carbide.

Abstract: A method and apparatus for unloading boxes, for example of vegetables, root crops and the like, comprises a mechanism (16) for lifting and tipping and lowering a box (14). The box (14) is carried on a power-lifted support (12). During tipping the support clamps the box to a control lid having a discharge funnel. The apparatus further comprises a fixed second support (20) located between the raised and lowered positions of the movable support. The movable support (12) can move past the fixed support (20) and can pick up from it a box (14) loaded thereon or deposit an unloaded box thereon. The fixed support (20) is movable out of the way of a box (14) carried on the movable support (12) if necessary. As a result, full boxes (14) can be received at either of the supports (12, 20) and empty boxes (14) can likewise be removed from either of the supports (12, 20) according to requirements.

Abstract: Disclosed is a method for preliminarily printing a blank for a tapered draw-formed body, which comprises transforming digital rectangular coordinates to annular coordinates so that the height of the rectangular coordinates is made to correspond to the height of a tapered plane on which the printed image is to be manifested and the change of the area of the tapered plane by a minute change of the height of the tapered plane is made equal to the change of the area of the annular plane. In this method, excessive flattening of the image in the lateral direction is prevented when the resulting preliminarily printed blank is draw-formed, and an image having a beautiful appearance and a high commercial value can be reproduced.

Abstract: In assays providing for measurement of the analyte based on the length of a region producing a detectable signal, results may be improved by providing for a region which is relatively small and captures either analyte or a component of a reagent system producing a detectable signal, where the amount of the component is related to the amount of analyte. Particularly, a narrow band is provided of concentrated dye which reacts with hydrogen peroxide in a cholesterol assay, so that the dynamic range which is measured may be expanded providing for higher sensitivity, shorter wicking distances, and shorter times for wicking.

Abstract: The field of the invention is that of digital audio signal compression. The invention applies in particular to the transmission of sound signals on digital channels, and to devices for storing digital sound signals. The invention relates to an apparatus for compressing an audiodigital signal, using an apparatus for allocating bits which are available for transmission or storage of the signal, driving means of adaptive quantisation of the signal, so as to permit a significant reduction in the throughput whilst preserving to the maximum the quality of the starting signal. According to the invention, the apparatus comprises means (16) of allocating a specific number of bits in order to express the coefficients of each frequency band of a transformed audiodigital signal (12) as a function of an auxiliary item of information (19) corresponding to a description of the spectrum of the said signal (12), the said apparatus being informed by means (14) of prior elimination of spectral components of the said transformed signal (12) as a function of a psycho-acoustic criterion. <IMAGE>
