Abstract: A miniature fuse which has a fusing conductor (7), which melts in the event of an overload, in a gas-filled or evacuated chamber (9), which is sealed in a pressure-proof manner, is characterised by the arrangement of a metal surface (14) in the vicinity of the fusing conductor (7) in the chamber (9). The design of the metal surface (14) and its position with respect to the fusing conductor (7) are selected such that the arc (10) occurring on the fusing conductor when the fuse ruptures can transfer onto the metal surface (14), so that at least one secondary arc (11) is produced in parallel over the metal surface (14). As a result of the melting of the metal surface (14), so much heat is absorbed that the secondary arc (11) is extinguished.

Abstract: A liquid-crystal display device comprises a multi-layered-type liquid-crystal cell that is composed of at least first and second cell layers (C₁, C₂), the cell containing liquid-crystal molecules with a twisted nematic orientation therein. The angle of twist of the liquid-crystal molecules in the first cell layer (C₁) is opposite to that of twist of the liquid-crystal molecules in the second cell layer (C₂). The orientation of the liquid-­crystal molecules in the first cell layer (C₁) in the vicinity of the second cell layer is at an angle of 70° to 150° to that of the liquid-crystal molecules in the second cell layer (C₂) in the vicinity of the first cell layer (G₁). The first cell layer (C₁) has a voltage-applying means that changes the orientation of the liquid-crystal molecules therein and the second cell (C₂) layer is a cell layer that does not change the orientation of the liquid-crystal molecules therein.

Abstract: The invention relates to a microstrip to stripline transition which achieves good electrical performance and permits easy, solderless disconnection. The upper portion (G2,D2) of the stripline (G2,D2,G3,D3) is partially omitted permitting a flying lead (22) which is bonded to the microstrip conductor (C1), and which extends across a gap at the transition, to be held in contact with the stripline conductor (C2) by a removable filler block (25), which replaces the omitted upper portion of the stripline. The air gap, and the width of the stripline and microstrip conductors adjacent the air gap,are dimensioned to form the electrical equivalent of a pi network to achieve a desired response. 
     The filler block is held in place, in one embodiment, by an elongated conductor (28) which bridges the upper and lower ground planes of the stripline and forms a short waveguide section encircling the transition. The waveguide section is dimensioned to favor only a desired TEM mode and suppress undesired modes for increased transition efficiency over a desired band. The side walls of the waveguide section are made wide to reduce radiation from the stripline adjoining the transition.

Abstract: The internal unit with a lye container, laundry drum and drive unit of a drum-type washing machine constitutes a system capable of damped vibration and, when an unbalance occurs in the drum, exhibits resonance phenomena at specific speeds. In washing machines which it is customary to use today, the inert mass of the vibrating unit is increased in order, thereby, to reduce the amplitude of the vibratory unit. The method according to the invention will make it possible, without increasing the inert mass, to accelerate the laundry drum to a spinning speed, even when the device for measuring the unbalance signals the presence of an inadmissibly high unbalance. In the method according to the invention, the amount and position of the unbalance in the drum is sensed and is evaluated by the microcomputer control as a control variable for the motor-current regulating device. The amount and position of the unbalance are decisive factors in controlling the electric motor so as to increase its speed. The method is suitable for washing machines with a microcomputer control.

Abstract: A spray calcination process is provided for decomposing a metal nitrate solution to form fine grain multicomponent metal oxide powders of selected composition of particular utility as superconductor precursor powders. Such precursor powders are produced in bulk quantities as high purity, reproducible, intimately mixed powders for conversion to high temperature superconductors. 
     A metal nitrate solution containing two or more metal constituents in a preselected ratio is sprayed as a finely atomized spray into a spray calcination zone where it is contacted with a hot gas stream for a residence time of less than 15 seconds at a high temperature between 200°C and 1100°C sufficient to vaporize the water of the nitrate solution and convert the metal nitrates to their corresponding oxides. The formed metal oxides are recovered from the gas stream as the desired metal oxides powders of selected composition which, where required, may be further sintered to form the desired superconducting metal oxide ceramics such as the Y-Ba-Cu-O and Tl-Ba-Ca-Cu-O superconductors.

Abstract: A pixel processor converts data indicating origin, direction, length and intensity of each of a set of lines forming a picture into a half tone bit map of the picture. The pixel processor organizes the picture into an array of similar half tone cells, each half tone cell being a rectangular array of pixels, by storing adjustable data indicating the size of a half tone cell and a pixel intensity threshold level for each pixel of a half tone cell. When processing each line, the pixel processor reads pixel data words out of the bit map, each pixel data word including at least one bit corresponding to a pixel along the path of the line. For each such bit, the pixel processor determines the half tone cell position of the corresponding pixel, determines whether the pixel intensity threshold level assigned to that half tone cell position is lower than the intensity level of the line and sets the state of the bit accordingly. After suitably altering relevant bits of each pixel data word, the pixel processor writes the altered pixel data word back into the bit map memory.

Alternately, the total number of documents are calculated by dividing the number of copy paper sheets sent to an inter­mediate tray, by the preset number of copies. Page entry is made in the copy paper sheets taken out from the intermediate tray, based on the total number of documents thus obtained. The total number of documents may be automatically counted. Accordingly, even though the documents are successively fed, starting from the last-page document, page entry may be made.
