Filed: 1991-10-04
Abstract: The preparation of soluble polyvinyl acetals which have a low degree of crosslinking and improved melt-viscosity behaviour by acetalisation of soluble polyvinyl alcohols with a low degree of crosslinking which have been prepared by hydrolysis or alcoholysis of soluble copolymers of vinyl esters and polyethylenically unsaturated monomers, such as, for example, glyoxal bisacrylamide, which copolymers have a low degree of crosslinking. In comparison with comparable uncrosslinked, soluble polyvinyl acetals, polyvinylacetals with a low degree of crosslinking according to the invention have greater structural viscosities and exhibit surprisingly advantageous properties during thermoplastic shaping, in particular during extrusion in plasticised form. The polyvinyl acetals with a low degree of crosslinking furthermore have improved mechanical properties compared with uncrosslinked polyvinyl acetals and are particularly advantageously suitable in plasticised film form for the production of laminated glasses.

Title: Displacement method of excavating tunnel - mixes displaced soil with liq. and then subjects it to pressure to form tunnel wall.
Inventor: FOPPE WERNER
IPC: E21D9/10
Filed: 1992-03-25
Abstract: A tunnel is dug by a machine which compresses some of the displaced earth between an inner and an outer wall. The earth is mixed with a liq. or paste-like substance which is then subjected to pressure which causes the mixt. to harden and form a self-supporting wall (a) for the tunnel. This self-supporting wall also provides a means to support the reaction to the thrust force exerted on the excavating machine as it is moved forwards. In this process the region at the rear end of the machine is at atmospheric pressure. In an alternative method of excavating a tunnel an air-lock is fitted in the tunnel and the region at the rear of the machine is subjected to gas pressure which also serves to harden the mixt which forms the tunnel wall. USE/ADVANTAGE - Excavating long tunnels. The excavated soil is used to form the tunnel wall.

Inventor: JEONG KI-HO
IPC: H03K19/0944
Filed: 1992-05-13
Abstract: A BiCMOS driving circuit includes a logic unit 31 for converting an input signal to a logic level, a high current driving unit 33 for driving the logic level with high current and formed of bipolar devices, and a speed improving logic unit 32 interposed between the logic unit 31 and high current driving unit 33 and formed of devices having a high input-impedance characteristic, for reducing the discharge time of the high current driving unit. By the use of CMOS inverter in the speed improving logic unit 32 instead of a conventional resistor which occupies greater chip area, the circuit is favourable for achieving high density of a semiconductor device. Since the discharge path of a transistor is formed by a MOS device having a high input impedance, the discharge time constant is decreased, thereby quickening the discharge speed which in turn greatly improves the operational speed of the circuit. In a modification (Fig 4B) instead of connecting the input of the logic unit 32 to the input of the logic unit 31 the input of the logic unit 32 is connected to the input of the logic unit 31. <IMAGE>
