Abstract: During tunnel driving with driving shields, reaction forces develop which as a rule are diverted to the end face of the tunnel lining. In the case of cast-in-situ tunnel lining, the shield circumferential friction and the pressure of the newly placed concrete on the end formwork (4) are not adequate to absorb the reaction forces occurring, which are therefore passed via the inner formwork (7) into the already hardened concrete in the rear area of the formwork. In order to shift the formwork rings (8) in an unimpeded manner by means of the erector (18) above the travelling carrier (19) after completion of a formwork section, the space inside the inner formwork (7) must remain free. Therefore, while a formwork ring (10) is being shifted from the end to the start of the area cased by the inner formwork (7), the reaction forces of the shield (1) are passed into the formwork by means of longitudinally adjustable supports (16) in the shield tail (15) via the brackets (17) arranged close to the end face (11) on the outer surface of the frontmost formwork ring (9). <IMAGE>

Abstract: The disclosure relates to a method for endpoint detection in a semiconductor wafer etching ysstem characterised in the steps of: 1) scanning a semiconductor wafer (10) with a narrowly focussed laser beam (24); 2) analyzing a reflected portion of the beam to determine a preferred parking spot (P) on a preferred flat area (#8) of the wafer; 3) parking the beams at the preferred spot; and 4) analyzing the reflected portion of the beam to determine when the preferred flat area has been etched through. The beam spot (18) of the laser beam (24) is amller than the width of the preferred flat area to eliminate noise generated at the transition boundaries of the flat area. Preferably, the wafer is scanned several times along the same beam path to permit the comparison of several scans to determine the preferred parking spot. The apparatus includes a beam forming assembled (62, 64, 66); a scanning assembly which causes the laser beam to scan across the wafer; a detection assembly (76) responsive to a portiom of the laser beam which is reflected off the wafer; and a controller (78) which operates the laser and the scanning assembly and which is responsive to an output of the detection assembly. When output of the detection assembly indicates a cessation of the characteristic etching curve, the controller develops an endpoint detection signal which can automatically shut down the etching system.

Abstract: A circuit device 2 (e.g. mounted on a printed circuit board) is connected to data network, to which network are also connected a plurality of other circuit devices 2 under power. On removal of such a circuit device 2, the output driver 21 connecting the circuit components 28,29 of the output device 2 to the communications bus 5 of the bus network is first disconnected from power, and only when its disconnection is stable is the circuit device 2 withdrawn. A control device device 20 of the circuit device 2 is connected to the control bus 4 of the data network, and before power is disconnected from the output driver 21, the control device 20 signals to the network so as to prevent other circuit devices 2 connected to the network from signalling on the network. Effectively, the circuit device 2 to be removed "occupies" the bus. This occupation is maintained until the disconnection of the ouput driver 21 is stable, and then the circuit device 2 can be removed from the network. Similarly, on insertion, the network is first occupied before power is connected to the output driver 21. In this way, it   becomes possible to prevent faults due to mis-signalling between the other circuit devices connected to the network when one circuit device is inserted or removed.

Abstract: The block of fins, consisting of fins (1) and register pipes (2) is connected to collectors which are constructed from plastic modules (3). Mounted tightly on the ends of the register pipes (2) are plastic bushes (7), which are welded to one wall of the collector module (3). This results in a tight, corrosion-resistant connection between the register pipes (2) and collectors. The production of the heat exchanger is particularly economical, because the connection of the register pipes (2) to the collectors can be done by welding plastic parts, which not only allows a rapid, tight connection but also a certain compensation of tolerance. The construction of the collectors from individual, prefabricated modules (3) allows a rapid, rational production of heat exchangers of arbitrary dimensions. <IMAGE>

Abstract: The transfer device makes possible different motional sequences of the holding means (40) for the sheet-metal parts to be moved through the metal-forming machine tool. The holding means are secured on travelling carriages (24, 25). The travelling carriages (24, 25) are cam-guided, travelling carriage (25) performing a transfer motion (82) out of a processing stage (86) into an idle stage (88), taking a sheet-metal part along with it. The return motion (84) is interrupted in an intermediate position (89) during the forming process performed on the sheet-metal parts. Travelling carriage (24) executes a transfer motion (83) out of the idle stage (88) into a processing stage (87) and a return motion (85) interrupted temporarily in an intermediate stage (89). The perpendicularly guided motion components of the cams (82, 83, 84, 85) serve for the take-up and deposition of sheet-metal parts in processing stages, the extended lowering motion (94) serving for the deposition of the holding means onto sliding tables which can be moved into the press. The low-mass construction using travelling carriages (24, 25) makes possible high accelerations in the motions. The use of intermediate deposition points (17) in the idle stages (88) considerably shortens the transfer motions.
