Abstract: A metal laminate gasket of the invention is used for an internal combustion engine having at least one hole (Hc) to be sealed. The gasket is basically formed of first (A11) and second (A12) metal plates extending substantially throughout an entire area of the engine. The first plate (A11) includes an annular recess (A11a) formed at an upper side around a first hole to form a stepped portion (A11b). The second plate includes a curved portion (A12b) to define a second hole to be located inside the first hole, and a flange (A12c) extending from the curved portion in a direction away from the second hole. The flange (A12c) has a thickness greater than the depth (A11a) of the annular recess. When the gasket is assembled, the flange is located above the annular recess. The flange provides surface pressure around the hole of the engine greater than that outside the recess when the gasket is tightened. The surface pressure around the hole may be precisely adjusted.

Abstract: The invention relates to read circuits for integrated-circuit memories, especially non-volatile memories. In order to improve the compromise between reading speed and reliability of the information read from the memory, a read circuit is proposed which is made up as follows: it includes a differential amplifier (AD), means (T1) for precharging the bit line before a read phase and means for equilibrating the input potentials of the differential amplifier before the read phase. The equilibrating means include a follower amplifier (AS) having an input connected to the output of the differential amplifier (AD) and connected up during the equilibrating phase in such a way that it injects a current for charging the bit line in a direction tending to nullify the output voltage from the differential amplifier (AD). A cascode transistor (T6, T7) can be used to speed up reading. <IMAGE>

Abstract: An olefins process is described which combines cracking of a hydrocarbon feedstock with the coupling of methane using an oxygen-affording gas such that the heat evolved in the exothermic methane coupling reaction is effectively transferred to the endothermic cracking process in a manner which does not allow the non-hydrocarbon products in the effluent of the methane coupling reaction to mix with the effluent of the cracking process. By combining the cryogenic requirements of the two processes, the refrigeration used in air liquifaction to separate oxygen for the methane coupling process can provide refrigerant nitrogen to liquify one or more of methane, ethylene and propylene which can be used in the cryogenic separation of the C2+ hydrocarbon products in the cracking process effluent.

Abstract: Within a handle (10), an inner pipe (42) extends from a connection nipple (14) as far as a shut-off valve (18). Said pipe (42) is enclosed by an elastomeric hose (44) and exhibits spaced-apart openings (46) into the interior of the hose (44). Rapid closure of the shut-off valve (18), which can be opened by hand counter to the force of a spring (30), causes a temporary superatmospheric pressure due to the excessively rapidly decelerated water column of the supplied water. In order to avoid a pressure surge in the supply line (38) and the accompanying disadvantages thereof, use is made of the inner pipe (42) with the hose (44) which is pushed over said inner pipe and temporarily expands, as a compliant wall, into a cavity (48). <IMAGE>

Abstract: A programmable semiconductor memory with filament or point diodes in the intersections of a matrix system can be manufactured with minimum dimensions and thus with a very high density owing to the absence of alignment tolerances. A possible problem is then posed by the strong leakage currents which may arise during programming owing to punch-through between adjoining diodes. Decreasing the leakage current through the use of a higher background concentration of the region in which these diodes are formed is not very well possible because this reduces the breakdown voltage of the pn junctions of the diodes too much. According to the invention, a more strongly doped surface zone is provided in said region between the diodes, which zone is situated at least at a distance from the diode points. In a specific embodiment, said zone extends less deeply into the region than do the diodes. The invention is based on the recognition that the breakdown voltage is determined by the location where the curvature of the diode is strongest. The said zone suppresses the leakage current to a high degree, while the breakdown voltage of the diodes remains sufficiently high.
