Patent DE-4337871-A1 (DE)
Title: Thin-film transistor mfr. leaving no impurities in channel regions - performing source and drain ion bombardment and ohmic contact formation prior to gate isolation and photoetching
Inventor: KIM JEONG
IPC: H01L29/45
Filed: 1993-11-05
Abstract: On a well-dried transparent glass substrate (11), source and drain electrodes (12,13) are deposited by vacuum evaporation and photoetching, and covered with about 100 nm of silicide film (14). A bridging layer (15) of semiconductor is added by plasma CVD and ion-implanted to form ohmic layers (16) on both silicides. After further photoetching the SiO2 or Si3N4 gate isolation (17) is superimposed and the gate electrode (18) is formed of 200 to 400 nm of metal (e.g. Al). The method gives a threshold voltage of 4 to 5 V, carrier mobility of 0.3 to 0.4 sq.cm/volt-sec and on/off current ratio of up to 10 million. USE/ADVANTAGE - For an active matrix liq. crystal display, the degradation of transistor properties by impurity particles is reduced together with mfg. costs and rejection rates.

Title: Floating fluid density measuring device
Inventor: SCHNIPPERING AXEL DIPL ING
IPC: G01N9/10
Filed: 1993-11-21
Abstract: The device provides continuous analogue measurement of the density of a fluid within a defined density range, using a homogeneous cylindrical float body, with a density which is half the density at the centre of the density range. The float body rotates about an offcentre axis and is coupled to a homogenous flat prismatic float with a density less than that of the min. measured density, via its rotation axis, so that the variations in the fluid density cause rotation of the float body. Pref. the density is indicated from the rotary position of the float body relative to the prismatic float, using a number of density indication lines marked along the cylinder mantle of the float body.

Title: The adaptation insole consists of a foot-shaped bag (1) which is filled with shot-like small balls, granulate (2) or light, easily movable washable materials
Inventor: JAEHNKE KLAUS-PETER
IPC: A43B7/28
Filed: 1994-01-18
Abstract: The adaptation insole (1) is a sole which is suitable in particular for summer and home footwear such as e.g. flat high-heeled sandals and sandals with e.g prefabricated flexible moulded sole, winter boots or soft, flexible and laceable canvas shoes which have adequate space in the front cap region and in the instep and may have a slightly reinforced or extended heel cap. In soft winter boots, the adaptation insoles have a relaxing effect as the foot feels a so-called sand-walking as a result of the circulating insert and the constant massage. The adaptation insole stabilises the circulation and prevents fatigue phenomena, perspiring feet, sweating, states of weakness and cold feet, helps in physical posture in association with flexible and airy, light high-laced shoes to prevent knock-knees as the movement by means of the adaptation insole always takes place via the tips of the toes in order then to act rewardingly beneficially. As a result of the small balls (2) which are situated in the insole (1) and are easily movable, the mass (2) is moved during walking movements from the toes to the heel and presses beneficially under the longitudinal/transverse arch. As a result of the constant movements, the foot bed changes constantly. During standing, the foot presses into the foot bed which is ideal for it and thus supports foot bone and spinal column. The adaptation insole is washable and very ... Original abstract incomplete. <IMAGE>

Title: Detecting leaking exhaust valve of vehicle
Inventor: MEZGER MANFRED DIPL ING
IPC: F02D41/22
Filed: 1994-06-10
Abstract: A measure of the rough running of an engine is formed using a suitable device and air is fed into the region after the exhaust vale in the flow direction of the engine's exhaust gases. A first measure (LU1) of the running roughness of the engine is obtained without air fed into the above region and a second measure (LU2) obtained with air fed in.

Title: Interference measurement system for digital telephone network using intermittent carrier signal
Inventor: WANIERKE OTMAR DIPL PHYS
IPC: H04B17/20
Filed: 1994-08-26
Abstract: The interference measurement involves random interference signals (I) which arrive at the mobile receiver of a digital telephone network in addition to the carrier signal (C) from system transmitters or other sources, and examines signal data from successive time-slots (Z1-Z4). The composite signals formed by the sum power (S) of carrier and randomly occurring interference signals are synchronised to the system timing and the content of each time-slot is digitised, stored, and averaged. A known system of pulse compression is applied to the time-slot signals (Sk,K) and a further average power obtained, whereby a process of comparison identifies slots where no carrier signal is present if power is less than a threshold, and the registered power is thus solely due to the interference signal (I).

Abstract: In a first connector housing A', a short-circuit contact piece 19 with an elastic strip 19c is provided positioned on the underside of a deflection space for a resilient lock arm 14. A short-circuit contact portion 19c3 of the elastic contact strip 19c is opposed to and spaced from a bottom wall of the deflection space. A portion 19d of the elastic contact strip 19c is opposed to the resilient lock arm 14, so that the elastic it can be deflected by the resilient lock arm 14. On a supporting frame 17 in a second connector housing B', a pair of terminal pins D" for detecting engagement are provided so as to be opposed to the short-circuit contact piece. As the first connector housing A and the second connector housing B are brought together, the resilient lock arm 14 is deflected to deform the contact strip 19C so that it does not make contact with the terminal pins D". When the housings are fully engaged, the lock arm 14 mates with an opening 16a and so releases the contact strip 19c into engagement with the pins D", the resulting short circuit signalling engagement of the connector. <IMAGE>

IPC: A61C13/12
Filed: 1992-03-11
Abstract: The invention relates to a process and device for the production of especially dental saw-cut models in which for at least one saw blade (2), the direction of cut to produce a dental saw stump is established via a separation light provided in the blade plane and displaceable vertically, a laser beam (19) or the like.
