Patent DE-3149256-A1 (DE)
Title: Ultrasonic range finder
Inventor: NOVAK PAVEL DR ING
IPC: G01S11/14
Filed: 1981-12-11
Abstract: The invention relates to an ultrasonic range finder comprising a transmitter (1) for emitting ultrasonic pulse bursts (I), a receiver (3) and a measuring and evaluating circuit (5) for measuring the transit time of the pulse bursts between transmitter and receiver. The received signal (U1) is compared with a variable threshold signal (U4), internally derived from the shape of the pulse burst, in a comparator. This threshold signal is additively composed of two signals (U2, U3), one of which (U2) approximately corresponds to the maximum positive amplitude of the received signals (U1) and the other one of which approximately corresponds to the envelope signal of at least the first negative halfwaves of the received signal. This signal can be advantageously formed by two peak value detectors (15 and 17, respectively) having different time constants. A threshold signal (U4) generated in this manner ensures that the received signal (U1) always intersects the threshold signal with the same positive halfwave. This edge-triggered point of intersection is used for determining the transit time. <IMAGE>

Patent DE-3229576-A1 (DE)
Title: Compact underground silo vessel installation (of the underground silo type) for storing liquefied petroleum gas (LPG) in such a manner as to protect the environment
Inventor: LOHR KARL W R DIPL ING
IPC: F17C1/00
Filed: 1982-08-07
Abstract: The invention relates to a compact underground silo vessel installation for the highly secure storage of liquefied petroleum gas, in which installation a cylindrical steel storage tank, designed as a pressure vessel, is mounted in a frictionally locking manner in a reinforced-concrete vertically arranged annular shaft constituting a "composite arrangement". Mounting is effected in such a way as to protect the environment, to prevent floating, to provide resistance to earth pressure, corrosion and fire and, if necessary, to allow removal. This object is achieved in that the vertically incorporated pressure vessel is located, within the annular shaft, in a frictionally locking manner on the reinforced-concrete baseplate, and a frictional connection is produced, between the baseplate and the top-section casing part, by means of a plurality of clamping anchors cast in place in the baseplate. This has the effect that, in the event of floating due to groundwater or flooding, all the components forming the annular shaft, held together in a frictionally locking manner, give a composite arrangement which means the pressure vessel can be easily fitted and removed, protects it from floating, protects it against earth pressure, and makes it entirely suitable for driving over. In addition, the composite arrangement requires a minimal amount of space, makes the pressure vessel easy and safe to drive into, and includes fully automatic scanning of the wall thickness by ultrasound. The invention is mainly used in order to fulfil, in a cost-saving and economic manner, the requirements of the Federal Air Pollution Control Act and the legal regulations on fire-hazard protection.

Title: Self-adjusted power MOSFET with integral source-base short circuit and method for the manufacture thereof
Inventor: LOVE ROBERT PAUL
IPC: H01L21/336
Filed: 1982-10-29
Abstract: The source, the base and the drain zones (88,76,64) of a double-diffused power MOSFET correspond to the emitter of the base and the collector of a parasitic bipolar transistor. Double-diffused power MOSFETs operate better when they have an ohmic short circuit (104) between the source and base zones (88,76). The source connection consists of a metal electrode (102), preferably aluminium, and the short circuit (104) consists of at least one micro-alloying tip which extends from the source connection metal electrode through the source zone (88) and, in part, into the base zone (76). In another development (Fig. 11), a V-groove (106) is developed by preferred etching such that it extends through the source zone (88) and only partly into the base zone (76). A metal source electrode (102) introduced into the V-groove (106) is in ohmic contact with the source and base zones and forms both the source connection and the ohmic short circuit. Both developments of the short circuit simplify the construction and the method of manufacture of the MOSFET with a minimum number of masking steps, self-adjustment, and a larger active device surface.
Patent DE-3246022-A1 (DE)
Title: Projection stepping machine with system for lighting reticle
Inventor: HERSHEL RONALD S
IPC: G03F9/00
Filed: 1982-05-17
Abstract: The system maintains the projected image of the wafer patterns on the reticle in focus on the semiconductor die. Three pneumatic probe lines extend through a block which extends down from the housing for the projection system. Downwards movement of the chuck of the wafer positioning system varies the pressure of air in the probe lines. This causes each of three piston-cylinder assemblies spaced around the periphery of the chuck to be energised to regulate the position of the chuck. As a result the spacing of the block from a wafer on the chuck is controlled to keep the die on the wafer in focus with the projected image of the reticle pattern.
