Abstract: Une installation de couture de bandes de tissu, dans laquelle la bande de tissu est soutenue sur toute sa largeur sur une plaque de base agencée entre deux poulies de renvoi, comprend des dispositifs tendeurs agencés des deux côtés de la bande de tissu qui étirent en continu la bande de tissu transversalement à sa longeur et qui accrochent ses zones dépourvues de poils. Des plieurs des bords de la bande de tissu sont montés sur la plaque de base, des deux côtés de la bande de tissu, et comprennent chacun une machine à coudre les bords repliés. Une paire de rouleaux entraînés par moteur accrochent les bords longitudinaux ourlés de la bande de tissu.

Abstract: A fast write-thru scheme is proposed for use in a multi-port static random access memory. This is achieved by operating the read and write ports of the SRAM circuitry in two separate but interleaved stages. In a first stage, a write path is set up comprising a write address decoder (244), an AND gate (245) connected to a clock signal (CE) and the write port (260) and latch (290) of a memory cell (200). In the second stage, a read path is set up comprising a read address decoder (254), a latch (290), read port (270-274) and a data out buffer (225). To minimise the write-thru access time, the asynchronous read path controlled by the read address is interleaved with the write path triggered by a write clock (CE), so that the read address is delayed with respect to the clock and the write addresses. Thus the write-thru access time becomes independent from the write time needed for overwriting the multi-port SRAM cell and equal to the read address access time (Taa) achieved in a fully static or asynchronous read operation. 
     The proposed timing scheme is particularly suited for structured and expandable multi-port SRAMs embedded on CMOS VLSI logic chips.

Abstract: An oil passage (120) is provided in an axially central portion of a spool (7) which is received within a valve housing (1) and rotatively driven by a pulse motor (6), and oil passages (12₁-12₅) passed diametrically through the spool (7) and connected to said oil passage (120), so that a hydraulic pressure from an input port (13) connected to a hydraulic pressure source (S) is selectively supplied to the oil passages (12₁-12₅) for selectively engaging and disengaging frictionally engaging elements of an automatic transmission. An axially acting load provided by the hydraulic pressure is received by a thrust bearing (10) mounted at an end of the spool (7). The supply of oil from the axial portion of the spool enables no side force to be applied, thereby reducing the frictional force and to enhance the sealability between the valve housing (1) and the spool (7).

Abstract: In known magnetic resonance devices shimming is applied on the basis of maps of field inhomogeneities obtained from two images of a slice of an object by formation of a ratio image thereof. This ratio image is processed in order to obtain shimming information. These known methods are time-consuming and cumbersome. The invention proposes a fast and simple shimming method which utilizes only one measuring sequence or a few measuring sequences. The shimming gradient (-dG) is determined from a time shift between an anticipated (t1) and a measured maximum (t1') of an echo resonance signal (ec) obtained by means of the measuring sequence.
