Title: Integrated circuit with MOS field effect transistors - reduced dimensions achieved by changing some parameters in permutation
Inventor: SCHLOETTERER HEINRICH DR RER N
IPC: H01L21/86
Filed: 1974-12-09
Abstract: Integrated circuit has MOS field effect transistors with the dimensions reduced by a factor alpha. The integrated circuit is built into an insulated substrate by the ESFI or MOS process. The desired properties of the integrated circuit are achieved by changing some of the parameters of the field effect transistors. The switching speed is increased by reducing only the length of the channel by the factor alpha. The length and the width of the channel and the overall dimensions of the circuit in the Y direction are reduced by the factor alpha in order to reduce the switching speed and the packing density. The overall horizontal dimensions and the operating voltages are reduced by the factor alpha in order to increase the packing density and to reduce the power losses.

Inventor: NOE EWALD
IPC: F24F13/072
Filed: 1975-02-28
Abstract: In order to achieve intensive aeration, i.e. a great air circulation with a high outflow speed, without those occupied in the room being disturbed by a draught, specially shaped profile strip inserts are inserted into the ventilation rail, in order that the air flow is conducted into the room at different angles ( alpha ), if appropriate, and direct blowing against objects to be particularly protected in the room is avoided. The ventilation rail has a ventilation duct (1) which is narrowed on the room side by structures (3, 4). These consist of profile strips (3) which are arranged in a mirror-inverted manner on the longitudinal sides (2) of the ventilation duct (1) and which are covered in changing sequence by a C-shaped profile strip (4). Arranged above the profile strips is a perforated baffle sheet (5). The inflowing air is thus uniformly distributed. <IMAGE>

Title: Object identification system with error minimisation - coordinates interrogation stations saturating and overlapping in operating region
Inventor: FUSBAN ULRICH F A DIPL ING
IPC: G01S13/78
Filed: 1975-08-26
Abstract: An object identification system using interrogation and responding electromagnetic signals transmitted between interrogating stations and the objects to be identified, usually aircraft but also ground objects, employs effective measures to produce a coordinated system of interrogations from different stations in the same region. The measures are designed to minimise errors in identification produced by signal overlapping or saturation of the responding systems. The interrogation stations are coordinated such that each is alloted a defined period of activity in a controlled time period. The length of the allotted periods is chosen to be sufficient to enable identification of all objects in the operating region, yet not too great to enable significant changes to occur between successive interrogations.
