Inventor: LOVGREN G
IPC: H02K15/12
Filed: 1981-03-04
Abstract: A coil having a slot portion intended to be arranged in slots in a stator or a rotor of an electrical machine is manufactured by forming a coil part including a bundle of electrically insulated conductors and insulation surrounding the bundle, arranging a portion of the coil part in a mould including at least two mould parts, surrounding the mould with a heat-shrinkable material which is penetrable by an impregnating resin, subjecting the thus composed product to pressing and heating in a tool which together with the mould gives the slot portion its final shape, the mould parts being spaced from each other to provide longitudinal gaps between their confronting longitudinal edges, and the heating of the product causing the heat-shrinkable material to shrink and retain the slot portion in its final shape after removal of the composite product from the tool, thereafter impregnating the insulation with an impregnating resin and transforming the insulation into a solid state.

Abstract: A process for depositing films of uniform thickness on silicon wafers at a uniform deposition rate among all wafers processed at the same time. The wafers are vertically oriented and arranged in a spaced-apart mutually parallel fashion and are supported within a horizontally-oriented long quartz tube which is evacuated at one end by a vacuum pump. A heating element surrounding the tube heats the wafers supported within it. At least one type of reactant gas is introduced into the enclosure in a generally confined region below the wafers and between the wafer arrangement and a wall of the enclosure. The gas, which is directed upwards between adjacent wafers and dispersed across the entire surface of the wafers, chemically reacts to deposit a uniform film on the wafers. Unreacted and exhaust gases are evacuated from the enclosure by the vacuum pump in a horizontal direction of flow above the wafer arrangement.

Abstract: Electronic device for the energization of an electromagnetic element, particularly a troke-coil or a coil of an electromagnetic switching apparatus having a magnetic circuit with a coil, a yoke and an armature. A comparator (5) receives a predetermined current order value U(I<usoll2>u) and an actual measured current value U (I<uist>u). Then the actual value goes down below the order value, the comparator (5) actuates, through a monostable flip flop element (6), a switching transistor (1) supplied by a supply voltage U<uv>u, arranged in the main current circuit of the electromagnetic element (2). After the constant conduction duration kin has elapsed, it blocks the transistor (1). With a variable conduction duration kin of the switching transistor (1), there results a variation of the current order value, function of the set conduction duration. In order to obtain a reliable operating mode of an electromagnetic switching apparatus comprising a coil, there is established a high actuation current order value and, after operation of the switching apparatus, a reduced maintaining current order value. For the operation of different switching states of the switching apparatus, the coil inductivity is taken into account.

Abstract: A screw-threaded fastener 10 for attaching articles 28 of predetermined thicknesses to sheet metal 30, the fastener 10 including a head 12 at one end, a generally cylindrical elongate shank, a tip 22 at the other end, a plurality of discrete threaded sections 26a and 26b on the shank and at least one annular unthreaded shank portions 24 between each pair of the thread sections 26a and 26b. The annular unthreaded shank portion 24 is spaced from the head at a predetermined distance or at predetermined distances which correspond to the predetermined thickness of articles to be fastened. Thus, when the head 12 of the fastener 10 is seated, the fastener is free to rotate without continued advancement with the sheet metal 30 being located at the unthreaded portion 24. Naturally when a plurality of unthreaded portions 24 are included the fastener 10 can accommodate articles of different thickness. The annular portions 24 can be given a greater axial extent to allow the screw to move relative to the panel when the panel is compressed in the vicinity, thereby preventing the screw head from penetrating an overlying membrane. <IMAGE>

Abstract: A component (1,2,4,5) is provided for parallel movement of a laser lobe in a measurement plane in accordance with a specific movement pattern, pref. with constant speed, in repetitive sweeps between two outer positions (Xa,Xb). The detector, dependent upon the laser light sensed, transmits a first signal to a computer (7), where such signal relates to a primary sweep of the laser lobe. During a second laser lobe sweep, the detector transmits a second signal to the computer. From the two received signals, the computer calculates the length (X2 - X1) of an investigate object. It is also preferable to obtain third and fourth signals from the detector, the third being the equivalent of the second signal from which the first signal value, multiplied by a factor less than 1, has been deducted. A fourth signal can be used by comparison of the third with a reference level, and comprises higher and lower signal levels from which a measurement value can be calculated with precision. This value is compared with the laser source calibration value to provided the true dimension of the investigation object. (Provisional basic advised week 87/01)
