Abstract: In a semiconductor memory device wherein memory cells (MC11, MC12) formed by a pair of multi-emitter transistors (TC1, TC2) each having a collector and a base which are cross connected to each other are arranged in row and column directions, and wherein read out transistors (T11, T12), each having an emitter which is commonly connected to one of the emitters of the multi-emitter transistors, are arranged in each column, the patterns of the multi-emitter transistors and the patterns of the read-out transistors are such that deviations in the intended patterns of the memory cell and read-out transistors occurring during the manufacturing process tend to balance one another. This result is obtained, for example, by using a similar disposition of emitter and base electrodes, or a similar arrangement of the emitter and isolation region in multi-emitter transistors of the memory cells and in multi-emitter read-out transistors, which have different emitters connected to bit lines of different columns.

Abstract: In an electron beam exposure system, a table (20) on which a target (18) was mounted is accelerated in Y direction and then decelerated. During this movement, the speed of the target is detected. An electron beam which is directed to the target (18) is deflected in X direction at a constant deflection rate by X deflection electrodes (12). The electron beam which passed through the gap between the X deflection electrodes (12) is deflected by Y deflection electrodes (14) at a deflection rate and from a deflection starting point in Y direction during the period of acceleration and deceleration. The electron beam then lands on the target (18). The deflection rate and the deflection starting point are determined by the moving speed of the table so as to draw on the table a straight line extending in the X direction. Thus, the target is exposed at high speed with high accuracy.

Abstract: In such methods use is made of longitudinal canal construction apparatuses whose lining rate exceeds that of transverse placing apparatuses. Since, however, only relatively small slope inclinations can be worked using longitudinal placing apparatuses, the transverse method of placing linings is superior in this regard to the longitudinal placing method. In order also to be able to employ the longitudinal placing method, with its high placing rates, to work relatively large slope inclinations, it is proposed to perform the levelling and/or the distribution, compaction and smoothing of the lining material at at least one of the slope surfaces (9a, 9b), continuously in each case on a slope line (24), which lies in an angular range ( alpha ) of approximately 15 to 45 DEG  to the horizontal (23), the associated angle of slope ( beta ) being perpendicular to the parallel to the longitudinal axis of the canal in the angular range from approximately 20 DEG  to 60 DEG  to the horizontal (23'). The longitudinal canal construction apparatus for carrying out this method is configured for this purpose in such a way that at least two rigs (1, 2) with their equipment items (13, 19a; 14, 19b) are arranged sequentially spaced apart in the longitudinal canal direction (28) on the slope line (24) rising obliquely upwards from below, and extending parallel to one another on the straight line.

Abstract: Branched polyamidoamines bearing a plurality of pendant aminoamide moieties exhibit properties which are superior to linear polyamidoamines from which the branched polymers are derived. The branched polyamidoamine is readily prepared by reacting a linear polyamidoamine with an alkyl acrylate or methacrylate to prepare a polymer with pendant ester moieties. The ester moieties are then reacted with an alkylene diamine or a polyalkyene polyamine to produce the pendant aminoamide groups. Ammonium polyamidoamines are prepared by contacting the branched polyamidoamine with an epihalohydrin to form curable ammonium moieties on the branched polyamidoamines. The branched polyamidoamines are particularly useful as curing agents for epoxides; as a demulsification agent, flocculant or dye retention agent. Ammonium polyamidoamines are particularly useful as agents for imparting superior wet strength properties to paper.

Abstract: Apparatus for producing annular corrugations in the wall of thin metal tubing in the manufacture of corrugated metal hose includes a plurality of annular dies (30'-40'). Each die comprises a helical rib (30"-40") of greater than 360° extent formed on the inner surface of the die with the ribs on successive dies being progressively thinner and having successively closer pitches so as to progressively deepen the corrugations (11a-11f) and make them narrower. The dies (30'-40') are mounted to rotate in synchronization with each other at identical angular speeds, and are arranged in pairs in one or more stages with the dies in each stage engaging opposite sides of the tube (11). A non-rotatable guide (28) projects inside the first die (30') and has an aperture (126) to permit the rib (30") of the first die (30') to contact the tube (11) at one location on the tube circumference while the remainder of the tube is rigidly supported against collapse by the guide (28). Transfer of the corrugations from one die to the next is assisted by providing the intermediate dies with lead-in portions (130-136) having the same pitch as the rib in the preceding die.

Abstract: A four-way diverter valve has a cylindrical housing wall (10) and two pair of in-line ports (16-19) for connection to a heat exchanger condenser (3) or the like. Disposed within the interior of the valve housing is a longitudinal hollow tubular fluid flow diverter element (20) mounted for rotation on a transverse axis (25) coinciding with the center axis of the cylindrical wall. The tubular diverter element is provided with an inner generally diametrical baffle (22) which forms separate but parallel fluid flow passages (23, 24) therein. 
     Diametrically opposed longitudinally extending radial ribs (35, 36) are disposed on the outer wall of the tubular diverter element and directly in line with the edges of the inner baffle. The end closure plates (11, 13) for the valve are provided with a first stop device (37, 40) for engagement by the diverter element ribs for properly positioning the diverter element in a normal position parallel to the in-line ports. A second stop means (43) is provided for rib engagement to properly position the diverter element in rotated position when the fluid flow downstream of the valve isto be reversed. Diagonally opposed ports (18, 17) in the valve housing are surrounded by concave seats (44, 45) which are inclined at an acute angle to the cylindrical housing wall and the axis of rotation of the tubular diverter element. The end edges (51) of the diverter element wall and baffle end (52) are slanted transversely at substantially the same angle to provide an engageable planular interface, in section, between the parts. Each seat (44, 45) extends circumferentially toward the other adjacent port (19,16) and crosses a central longitudinal plane (46) containing the axis of rotation of the tubular diverter element so that the seat terminates on the side of the diverter element baffle remote from the surrounded port when the diverter element is in normal position. An axle (26, 27) mounts the tubular diverter element for rotation about its axis. A device (53-59) is provided to shift the axle axially when desired. Thus, the diverter element and its associated parts can be tightened onto the seats, but also when the diverter element is to be rotated from its normal to its second position, the end edges of the associated parts can be lifted from the circumferential ! tapered seats for free subsequent rotation. Resilientseals (39,  !  42) are provided in association with the longitudinal ribs and stops. The seal is maintained during shifting of the diverter element along its axis.
