Abstract: 1. An apparatus for the transfer of digital signals, comprising a character transmitter and a character receiver, having a first, continuous parity counting operation performed on n bits at a time of the character stream to be transmitted and with insertion of a parity bit, dependent on the particular results of this first parity counting operation, into the character stream to be transmitted on the transmitting side, as well as a second, continuous parity counting operation performed on the same n bits of the character stream to be received and comparison of the result of this second parity counting operation with the received parity bit for the purpose of error recognition on the receiving side, characterized in that on both the transmitting side and the receiving side, the input of the parity counter (P ; Fig. 2) is in each case preceded by a scrambler (S), in such a manner that the character stream to be transmitter and the character stream to be transferred via the transfer channel (Ü) are statistically decoupled from the input data of the parity counter (P).

Abstract: The present invention is concerned with a method of molding metallic powders, in which a binder fluid having a specific freezing point, typically water, is added to the metallic powder to be molded to form a mixture, after which a die having the desired cavity is filled with said mixture. The mixture is then pressure molded and rapidly cooled, freezing the binder fluid to produce a frozen molded shape, which is then dried to remove the binder fluid and sintered. The amount of the binder fluid of specific freezing point to be added to the said metallic powder is the minimum amount that will satisfy the dual demands of flowability during molding and shape retention after the removal of the binder fluid, with from 25 to 50 vol% generally being appropriate. Molding is achieved by injection molding, compression molding or other technique in which pressure is applied to the material in the mold. The present invention makes possible the easy and economical mass production of sintered products of complex shape, high dimensional accuracy, and high density using metallic material.

Abstract: On a semiconductor substrate (11), pref. Si, an oxide layer (12), pref. more than 100nm SiO2, is formed followed by a nitride layer (13), pref. more than 100nm thick Si-nitride. Then a photoresist layer is deposited and defined and the nitride layer etched. The oxide layer is then etched by a wet process. The feature is that in the next step the nitride overhang, caused by oxide-overetch, is removed and the nitride layer undercut until its boundary is a certain distance removed from the window formed by the oxide. Then the photoresist layer is removed. The passivation edge then shows 2 steps.

Abstract: By a method for connecting a plastic pipe end (4 and 4', respectively) to a plastic welding sleeve (1) a heater (3) of annealed expanded metal is initially mounted on the pipe end (4 and 4', respectively), whereafter the welding sleeve (1) is pushed over said pipe end. Subsequently the plastic welding sleeve (1) is pressed downwards to abut the heater (3) in question by means of a known clamping device and heat supplied from the outside. The heater (3) is then connected to a welding generator and a microprocessor measuring and controlling the current through the heater and the voltage across the heater (3) during the entire heating phase. During the first phase of the heating process the heater (3) is supplied with a constant current, and when the microprocessor registers that the increase in voltage per time unit has dropped below a predetermined level corresponding to a specific temperature, said microprocessor computes the ohmic resistance of the heater corresponding to a desired predetermined final welding temperature. This final welding temperature is kept constant for a period thereafter. In this manner a method is provided for connecting a plastic pipe end to a plastic welding sleeve by means of an extensible heater. During the fully automatized welding operation this heater is situated in the welding area, whereby a uniform distri bution of heat is ensured and results in a welding of high strength and quality.

Abstract: Connectors for fuel pumps in motor vehicles have fuel flowing around them. Apart from the connections for the electrical supply lines, such connectors make contact with further electrical components. Corrosive components in fuels attack the connecting points of the connector to the electrical components, so that this can lead to failure of the fuel pump. The new connector is intended to have connecting points which are no longer attacked by the fuel. By extrusion coating parts of the connector with plastic, the connecting points are effectively protected against attack by fuel. Recesses in the plastic extrusion coating allow fuel to still flow around parts of the connector for cooling, while the regions of the connector which are at risk are separated from the fuel.
