Patent DE-3366970-D1 (DE)
Title: Apparatus for uniformly heating a substrate
Inventor: EDGERTON ROBERT FRANK
IPC: C23C16/50
Filed: 1983-07-08
Granted: 1986-11-20
Abstract: Apparatus for developing a substantially uniform temperature distribution across the entire transverse width of a relatively thin, relatively large area substrate onto which a plurality of amorphous semiconductor layers will be deposited in a glow discharge deposition chamber. The apparatus includes a plurality of spaced heating elements, the filaments of which are suspended above and angled relative to the plane of the substrate so as to direct radiation onto that portion of the substrate which loses heat at the greatest rate with at least the same intensity as, and preferably greater intensity than, radiation is directed onto those portions of the substrate which lose heat at lesser rates. By establishing the greatest intensity of radiation adjacent that portion of the substrate which most readily loses heat, a uniform distribution of temperature across the transverse width of the substrate may be achieved.

Title: Method of producing dynamic random access memory cells (ram) according to the double polysilicon gate technology
Inventor: MULLER WOLFGANG DR
IPC: H01L21/266
Filed: 1983-02-14
Granted: 1986-12-11
Abstract: The invention provides a method of manufacturing dynamic semiconductor memory cells having random access (RAM) in accordance with the double polysilicon gate technology, with which insulation of adjacent, active regions occurs by thick oxide regions, produced according to known LOCOS technology and with which, for increasing cell capacity, a boron and arsenic ion implantation is executed into the memory region with the use of a photoresist mask. In order to increase component density, the oxide thickness in the memory region/thick oxide transistor region is reduced in a multi-stage etching sequence, axially as well as laterally, so that a gain of about 25% in memory surface and a gain of more than 10 volts in blocking bias is achieved. The inventive method is particularly useful in the production of LSI Si2 gate RAM memories.

Title: Gas convection oven
Inventor: BAGGOTT GEORGE T
IPC: A47J39/00
Filed: 1983-09-13
Granted: 1989-07-06
Abstract: A gas-fired convection oven for processing food, for example, having a fan (19) for moving air along a circulatory path over, along and about the food to be processed. A package type gas burner outside the oven is directed into a heat exchanger tube (28, 50-56) of substantial length extending into the oven. High-temperature exhaust gases are discharged from the burner to be directed through the heat exchanger (28, 50-56) into the circulatory path of air flowing through the convection oven. Relatively proximate the burner the heat exchanger (28, 50-56) has a linear portion (50, 65) that is of elliptical cross section, and that portion is oriented with respect to the outlet of the convection blower and walls of the convection blower chamber to draw air over substantially the entire surface area of such portion for maximum cooling/heat exchange function with respect thereto. The outlet (45) from the flow outlet of the heat exchanger (28, 50-56) is aerodynamic and is positioned proximate the intake to the convection blower wheel (19) whereby the latter tends to draw the hot gases/products of combustion through the heat exchanger tube (28, 50-56).

Title: Continuous casting furnace and method of continuously manufacturing cast product
Inventor: MAE YOSHIHARU
IPC: B22D11/00
Filed: 1984-11-09
Granted: 1988-06-01
Abstract: @ A continuous casting furnace for manufacturing an elongate cast product, for example, of copper or its alloy includes a housing (11) defining a chamber (12). A crucible (18) is accommodated within the chamber (12) for holding a casting material (26). A heater (19) is mounted on the crucible (18) for melting the casting material (26). A generally vertically-disposed elongate casting nozzle (23) hermetically extends into the chamber (12). One of the casting nozzle (23) and the crucible (1-8) is movable toward the other for immersing a lower end of the casting nozzle (23) in the molten casting material (26) in the crucible (18). The housing (11) is connected to an inert gas source (14b) for introducing inert gas into the chamber (12) when the casting material in the crucible (18) is melted. When the lower end ofthe casting nozzle (23) is immersed in the molten casting material (26), the molten casting material is moved along the casting nozzle (23) by the pressure of the inert gas in the chamber(12). A cooling device is associated with the casting nozzle for solidifying the molten casting material when it is passed through the casting nozzle, thereby forming the elongate cast product.

Title: Refresh generator system for a dynamic memory
Inventor: DEAN MARK EDWARD
IPC: G11C11/24
Filed: 1984-12-14
Granted: 1989-06-22
Abstract: A refresh generator system (5) for a dynamic memory (3) in a data processing system, including a processor (1) which is responsive to a hold request signal (HRQ) to relinquish control of the local bus and generate a hold acknowledge signal (HLDA), comprises logic means (14,11.10,13) to generate a hold request signal in response to an output from a refresh timer circuit (6). A logic circuit (16) is responsive to a hold request, a corresponding hold acknowledge, and the timer signal to generate a refresh control signal (REFR). This signal generates a refresh signal for the memory control circuits, increments a counter circuit (19) and initiates operation of a sequencer circuit (22). The sequencer then gates the output of the counter circuit to provide a memory row address and thereafter provides a memory read output (-MEMR) to refresh the memory row defined by the address and lastly resets the circuit to terminate the hold request signal.

Inventor: LAGERSTEDT JAN EBBE ROLAND
IPC: B01D45/16
Filed: 1984-08-14
Granted: 1991-02-14
Abstract: For the separation of particles, e.g. liquid drops, from a gas stream a vessel with an internal labyrinth is used in general through which the gas is conducted, whereby the particles are thrown out against the walls of the vessel and flow to the bottom of the vessel where they can be collected. Such known arrangements present great flow resistance and do not produce air which is sufficiently clean to be reused and applied under sterile conditions of the type prevailing in aseptic packing machines. 
<??>An arrangement for the separation of particles from a gas stream in accordance with the invention is provided with a helical guiding element (8) and a collar (9) fitted at the end of the same which is designed so as to have drop-forming elements (12). Consequently, on the one hand a strongly rotating movement is imparted to the air at a relatively low flow resistance, on the other hand it is processed by the drop-forming elements of the collar, which results in high capacity as well as effective separation.
