Title: Mfg. semiconductor with active region on insulating layer - heating non-monocrystalline layer with laser to form monocrystalline structure of specific temperature distribution, and producing semiconductor layer island via selective etching
Inventor: IPPOSHI TAKASHI
IPC: H01L21/20
Filed: 1992-10-07
Abstract: The semiconductor mfg. process involves the forming of a monocrystalline layer by heating a non-monocrystalline layer or an insulating layer (2) using a laser. The non-monocrystalline layer is melted such that it exhibits a specific temperature dispersion. A semiconductor layer island is produced by selective removal of the monocrystalline layer, at a region of higher temp. during melting. This region is then treated to form an active region (61). The surface of the monocrystalline layer may be polished before active regions are formed to provide an even surface. ADVANTAGE - Heat treatment process does not produce additional crystalline defects, improved current handling characteristics, eliminates leakage current in MOS transistors.

Title: One-sided adhesive tape on rolls in ready-to-use lengths with non adhesive gripping pieces
Inventor: STROBEL FRIEDRICH
IPC: C09J7/20
Filed: 1993-06-03
Abstract: For numerous everyday applications it is advantageous to have available, without further aids, adhesive tapes in ready-to-use lengths. Ready-to-use lengths which need only be pulled off from a convenient roll are very advantageous, especially when working positions are unfavourable. The nonadhesive gripping pieces, and the fact that, in accordance with the invention, the pull-off direction of one ready-to-use length is different to that of the next, on the one hand make it easy to find the beginning of each length and, on the other hand, ensure that only one ready-to-use length is pulled off in each case. Pulling off more than one ready-to-use length would cast doubt on the use or utility, since relatively long adhesive tapes are very difficult to control, especially with one hand, and rapidly become tangled or adhere to places where this is definitely not intended.

Title: Building
Inventor: VAHLBRAUK KARL HEINZ
IPC: E04B1/18
Filed: 1993-10-30
Abstract: In order to simplify the assembly along with simultaneously large-scale industrial prefabrication of structural components, in order to improve the wear behaviour and the possibilities for making subsequent changes and in order to improve the fire safety, the invention proposes a building construction whose essential structural parts, e.g. exterior walls (10), floors, roof (13), are all designed by standardized construction principles and comprise a framework, intended for absorbing static loads, and heat-insulating panels (3, 6) which line and/or cover said framework. While the bars which form the framework are designed as hollow components made of a compact geopolymer material, the panels consist of geopolymer foam materials, with the result that the bonding of the framwork to said panels produces a building with complete material homogeneity. In addition, a roof gutter (20) and a chimney (19) may likewise consist of a geopolymer material and be bonded to the rest of the structural parts of the building with material homogeneity. The result is a building which, due to the material selected, along with a simple assembly technique, has to be regarded as extremely wear-resistant. <IMAGE>

Patent DE-4418701-A1 (DE)
Title: Vehicle disc brake piston
Inventor: DREWS REINHARD DR
IPC: F16D65/14
Filed: 1994-05-28
Abstract: The brake piston (2) is made up of two pistons (3,4), both adjustable by a roll-back seal (11) acting on piston (3) only. Only the second piston moves under lower pressure, followed by the first only at higher pressure load. The second piston rides in the hollow cylindrical piston (3) whose annular face (12) on the end furthest from the shoes has a sealably fitted end diaphragm (13) which closes off the first piston section and when loaded by pressure medium acts on the non-shoe end of the second piston. This is a metallised diaphragm being in circular form and annularly corrugated (15). The first piston passes its braking force to the shoe via a stepped part (19) of the second piston. Entrained shoe pistons at high load overcome the roll-back seal during braking but re-set to a leave wear-preventing gap between pad and disc for longer service, using the diaphragm to react to increasing load and progressive piston movement.
