Patent DE-3023410-A1 (DE)
Title: Miniaturisation method for MOS structures - employs trench etching and deposit of silicon compound
Inventor: BUSSMANN EGON DIPL PHYS DR
IPC: H01L21/762
Filed: 1980-06-23
Abstract: In order to increase miniturization in the fabrication of MOS structures the method makes tolerances less critical by automatic alignment of gate and source-drain regions and increasing the conductivity of source, drain and gate. This is achieved by separating the source-drain diffusion from the field diffusion by means of trench etching and depositing of silicon compound on source-drain regions. Gate-oxide is deposited on a substrate and the subsequent implantation employs conventional photolacquer masking. A further step comprises the structuring of source-drain regions with trench etching and p-implantation. This is followed by filling with silicon oxide whose selective growth results in self- alignment of gate and contact regions.

Title: Joint fitting for lozenge-shaped trelliswork structure
Inventor: SIEBERT ALBRECHT
IPC: E04B7/02
Filed: 1981-07-27
Abstract: The lozenge-shaped trelliswork structures, common a number of decades ago, for hall roofs have weaknesses which have prevented their application on a wider scale. The use, according to the invention, of articulated joint fittings improves such structures with regard to the following points:   1) Trelliswork division and shape of the trelliswork and of the supporting surface can be selected in accordance with design and/or cost criteria. 2) Use is made of commercially available, straight-axis bars comprising round, rectangular, web-type or box-type profiles, or of latticework. 3) Transfer of stress resultants by the joint fittings always takes place in a systematic manner via the end-plate articulation bolts (7), even in the event of unforeseen, considerable deformations by unforeseen loads.   4) Mass production by standardisation of the joint fittings. 5) Full assembly of the individual trelliswork parts by the manufacturer. All that remains to be done on the building site is to position the lightweight structural part appropriately, to insert the suspension bolts (3) into the outer butt-straps (2+5), to tighten the articulation bolt in the joint axis (1), and to connect the spacer rod (12) with a turnbuckle (11) on the threaded end (10). 6) Fireproofing requirements can be easily satisfied in a cost-effective manner by suitable choice of bar material and trelliswork-division width. 7) Production and mounting are possible without extensive, special fitting-out, and widespread application is therefore obtained.   <IMAGE>

Title: Pump unit
Inventor: MASUDA NAOSUKE
IPC: F04C2/344
Filed: 1981-08-14
Abstract: A plurality of pump sections (7, 8) are accommodated in a stack in a body. Each pump section has a cam ring (9, 17) which is arranged around a rotary piston (12, 19) provided with vanes (13, 20), and two end plates which seal the opposite sides of the cam ring. All the pump sections (7, 8) are driven by a common drive shaft (14), which results in a compact pump unit which has a reduced axial length. The outermost end plates are subjected to the delivery pressure from the pump sections in question, so that the various components of the individual pump sections are retained on the body under pressure. Thus the components are retained in a defined, accurate position, the probability of liquid leaks is minimised, and the construction is simplified. <IMAGE>
