Abstract: An integrated circuit with a memory, comprising a matrix of memory cells and sense amplifiers which are coupled thereto, the inputs of the sense amplifiers being connected to one another, the outputs of the sense amplifiers being connected to one another  via  a read bus. During the reading of inforamtion from a memory cell, the sense amplifiers are simultaneously activated. As a result, the access time for reading information from a a memory cell remains substantially constant when the number of memory columns to be connected in parallel is changed. The dimensioning of the sense amplifiers may remain the same when the number of memory columns is changed, so that dimensioning need be performed only once. This results in a saving as regards time and costs.

Abstract: This device comprises a fastening station (1) equipped with magnetic induction coils (7) supplied by a generator (9) and with a support (8) for sliding parts (2); the piston (5) is heated before its head (3) is introduced into the sliding part (2) in a regulated furnace (11), and is then transferred to the fastening station (1) in a tube (9) by means of a jack (13). A discharge of the generator (9) into the coils (7) causes the sliding part (2) to be fastened to the head (3), with an extremely small play and swivelling torque and a virtually zero axial play being produced. This fastening method guarantees that a greatly reduced play and swivelling torque are obtained and therefore a higher efficiency of the pump for a longer period than pumps in which the pistons are equipped with sliding parts fastened mechanically. <IMAGE>

Abstract: A folding package (10) is produced from a single foil web (12) which is folded around an article to be packed and then sealed in such a way that the article is hermetically sealed by it on all sides. Here, the closure is made by adhesively securing the opposite edge regions of the foil web which border the inner region thereof. According to the invention, two opposite edge regions (26, 28) have at least one area (50, 60, 72, 74) which does not adhere permanently, whereby these areas overlap (29) in when the foil is folded to form a package (10), and one of these two edge areas (50, 72) is partially physically separated from the remaining edge region (26) along its peripheral line (54, 70, 52). The adhesive layers (40, 42) lie between these two areas (50, 60 or 72, 74) and the inner region (22, 14, 16, 18, 20) so that the inner region is laterally completely surrounded by the adhesive layers (40, 42).

Abstract: An eddy current type brake system adapted to a vehicle comprises a drum-like rotor (4) mounted on an output shaft (1) of a transmission of the vehicle, a stator (7) provided in the rotor (4) and being able to reciprocate in an axial direction of the rotor (4), a plurality of permanent magnets (10) mounted on the stator (7), a brake device (17) provided between the stator (7) and the rotor (4) for magnetically connecting the permanent magnets (10) of the stator (7) with the rotor (4) to apply brake force to the rotor (4), and device for magentically cutting the permanent magnets (10) of the stator (7) from the rotor (4) to release the brake force from the rotor (4). When the stator (7) is moved to a position to face the brake device (17), the permanent magnets (10) of the stator (7) are connected to the rotor (4) magnetically and the eddy current is produced in the rotor (4) so that the rotating shaft (1) is decelerated. On the other hand, the deceleration force is no longer applied to the rotor (4) as the stator (7) is moved to face the releasing device (18), since the permanent magnets (10) of the stator (7) are magnetically disconnected from the rotor (4). The magnetism of the permanent magnets (10) is shielded by the releasing device (18) so that the magnetism does not leak to the rotor (4). Therefore, it is possible to design a drum (4) which has a larger drum (4) width along the entire path of the reciprocating movement of the stator (7). It is possible to enlarge the surface area of the drum (4) and to improve a heat releasing property of the drum (4).

Abstract: Heating units, via which the yarn is guided at high speed, are brought to a temperature which the stationery yarn would not withstand. Consequently, if the yarn comes to a standstill, for example as the result of a power failure, the heating unit is contaminated by the melting yarn. The heating unit (5) is assigned a drive (15) which actuates a lifting-out yarn guide (14) and which moves to and fro between an operating position and a position of rest. The drive (15) is actuated in such a way that, should there be an electrical power failure, an increase in the distance between the yarn (2) and heating unit (5) occurs. This therefore prevents the possibility that the yarn will be damaged, even in the state of rest. <IMAGE>
