Patent DE-3102424-A1 (DE)
Title: Plastic sleeve for the provisional centring and fastening of the anchor plate of bar tensioning members in the thread region of the tensioning bar
Inventor: ANDRAE HANS-PETER DIPL ING
IPC: E04C5/12
Filed: 1981-01-26
Abstract: The invention relates to a plastic sleeve for fastening and centring the anchor plate of bar tensioning members and for connecting the sheathing to the anchor plate in a sealed manner. For this purpose, the plastic sleeve is provided with an internal thread which engages into the bar thread. During fixing by a lock nut, the anchor plate is fixed between the sleeve and a lock nut and is thus connected to the sheathing in a sealed manner. Known moulded plastic parts with internal threads are expensive and unfavourable from a technical point of view since, during the tensioning procedure, the plastic thread teeth shear off and block up the grooves which have been provided for the subsequent mortar throughflow. In order to render production less expensive and to avoid chip removal from the thread turnings during tensioning, the plastic sleeve according to the invention comprises a thin-walled, inflated tube (Figure 1.1), the casing of which is corrugated at one end, with the aid of a mould which can be drawn off from outside, as female thread for the bar thread and which exhibits, in this thread region, outwardly arched beads running in a longitudinal direction. The said beads act, during the tensioning procedure, as springs which permit the plastic thread to expand without having a chip-removing effect. <IMAGE>

Title: Sensor for measuring physical data, process for its production and its use
Inventor: SCHAUMBURG HANNO PROF DR
IPC: G01K13/00
Filed: 1981-03-16
Abstract: The sensor for measuring physical data comprises a poorly conductive, flat substrate, on which there are predetermined doped areas of polycrystalline silicon. From these areas representing measurement figures, conductor tracks lead to the outer edge of the sensor. A passivation layer of quartz, silicon nitride or protective coating is applied to the sensor. The geometrical definition of the measurement figures and conductor tracks is effected by lithographic and etching processes. The processing of the polycrystalline silicon comprises doping, subsequent heat treatment or subsequent irradiation by a laser or an electron beam for adjusting to preset layer resistances. The field of application for the sensor is, in addition to the measurement of the most diverse physical data, for example the measurement of the body temperature for medical examinations, with an extremely short reaction time, high measuring accuracy and long-term constancy.

Patent DE-3117719-A1 (DE)
Title: Non-volatile EPROM and EEPROM of increased efficiency
Inventor: HARARI ELIYAHOU DR
IPC: G11C16/04
Filed: 1981-05-05
Abstract: The floating gate in an N-channel EPROM cell extends over the drain diffusion region and over a part of the channel to form a "drain" capacitance between the drain and the floating gate and a "channel" capacitance between the channel and the floating gate. A control gate overlaps the floating gate and extends over the remainder of the channel close to the source diffusion region to form a "control" capacitance between the channel and the control gate. These three capacitances form the coupling for driving each cell. The inversion region in the channel directly underneath the control gate is reached directly by a "write or read access" voltage, which is applied to the control gate. The inversion region in the channel directly underneath the floating gate is reached directly through the drain and control capacitances and the channel capacitance by the control gate voltage and by another write access voltage, which is applied to the drain. The drain voltage is namely coupled to the section of the channel next to the drain through the series drive circuit which is formed by the drain capacitance and the channel capacitance. During writing, hot electrons from the write channel current are directed and injected into the floating gate through the transverse electric field between the floating gate and the channel lying thereunder. Stored injection charging on the floating gate increases the conductive state threshold of the programmed cell, the cell remaining non-conducting during reading, when customary or low access voltages are applied to the control gate. An unprogrammed cell conducts in a way dependent on the low read voltages which are applied to its control gate and to the drain drive circuit. The cell is erased either by ultraviolet illumination or by electrons from the floating gate which tunnel through a region of dilute oxide. The asymmetric arrangement of control gate and floating gate with respect to source and drain makes it possible for the arrangement to be very compact.
