Title: Voltage supply device with AC-fed full=wave rectifier e.g. for discharge lamp lighting system
Inventor: NARUO MASAHIRO
IPC: H02M7/06
Filed: 1996-02-14
Abstract: A voltage supply device with a full-wave rectifier fed from an AC source has a voltage stabiliser circuit in parallel with the load. There is a switch and an energy store at the terminals of the rectifier with a control for the voltage of the energy store. The control is such that the sum of this voltage and the stabiliser voltage is proportional to the input voltage and the difference voltage between input and output appears at the energy store, so that a required direct voltage is supplied to the load. By this means an envelope curve of input current is proportional to the input voltage.

Abstract: The voltage applying circuit includes two control units for respective memory block selection and wordline selection. The non-volatile memory is provided with several memory blocks, each having row and column array-formed memory cells and each cell being connected to several series connected memory FETs. Also included are an address buffer, a predecoder, and a voltage generator for supplying e.g. load, read, write, erase, and program voltages to detect defects inside a memory block.  The memory block selection control unit selects the block to which a program voltage should be applied, as well as the following block to be chosen. The wordline selection control unit selects the wordline to which the load voltage should be applied. In a defective cell detection mode, the load voltage is applied to a wordline of a chosen memory block and an earth voltage is supplied to a wordline of a non-chosen block, the chosen wordline being connected to a memory transistor in the selected block. This test is repeated for each block.

IPC: B28B15/00
Filed: 1996-05-30
Abstract: The transporting mechanism (8) moves green freshly moulded tiles to a gripping device which loads them e.g. onto a pallet.

Title: Water vapour permeable and water repelling material production
Inventor: WIRZ PETER
IPC: E04D12/00
Filed: 1996-10-12
Abstract: A basic material for the clothing and shoe industries is permeable to water vapour, but resists the passage of water and comprises a layer of a flat knitted textile material (3) and a layer of a thermoplastic melt blown fleece (2) based on microfibres with a  weight of 10-100 g/<2>m, preferably 20-70 g/m<2>. The layers (2,3) are laminated to each other using heat and pressure which plasticises the fleece (2) fibres and compresses them to form a film-like layer (4) with a smooth surface. The size of the pores remaining in the film (2a) allows permeation by water vapour, but prevents passage of water.  In a process for manufacturing the basic material the textile material (3) and the melt blown fleece (2) are fed together into a gap between two continuous conveyer belts which apply a pressure of 5-30 kN/cm<2> at 90-180  deg C for at least 10 seconds. The layers (3,4a) form a laminate (4) as the fleece (2) fibres melt and are compressed to form a porous film (2a).

Title: Method of axle load dependent distribution of brake power in brake system of vehicles
Inventor: STENDER AXEL
IPC: B60T8/26
Filed: 1997-02-24
Abstract: The method involves using sensors (1,2,10,11) for detecting the rotational speed of the vehicle axles. The sensors emit a first rotational speed signal (V1) assigned to the first vehicle axle, and a second rotational speed signal (V2) assigned to the second axle. Brakes (3-6,12-15) are provided for decelerating the vehicle axles, which can be actuated depending on a first and second brake requirement signal (P1,P2). The method further involves using first and second coordination mechanisms (20,21) for generating the first and second brake signals (P1,P2). An auxiliary signal (M2) is provided as the second input signal for the second coordination mechanism (21), which is determined on the base of the first and second rotational speed signals (V1,V2).
