Patent DE-3170264-D1 (DE)
Title: Light source unit for an optical apparatus
Inventor: HATTORI SHINICHIRO
IPC: G02B23/16
Filed: 1981-06-29
Granted: 1985-06-05
Abstract: A light source unit for an endoscope is provided with a light-emitting element and a light receiving element which are provided in an eyepiece section of an endoscope. The light-emitting element is supplied with current modified by a specific frequency from an oscillating circuit and produces a light-intensity modulated light. An output signal from the light receiving element is supplied to a filter circuit and a signal of the specific frequency component is taken out from the filter circuit to be compared with a reference voltage in a Schmidt circuit. When an operator approaches to the light receiving element and enters a range within a predetermined distance from the light receiving element, a light intensity of the light which is emitted from the light emitting element toward the operator, reflected from the operator, and is incident on the light receiving element, becomes large. As a result, a signal level supplied to the Schmidt circuit exceeds a predetermined value. At this time, a signal for turning on a light source is produced from the Schmidt circuit to energize a relay and to close a contact of the relay. Then, electric power is supplied from a power source to the light source to turn on the light source. As a result, an illuminating light is supplied from the light source to a light guide of the endoscope, whereby an area of an objective portion can be observed through an image guide of the endoscope.

Title: Use of naphtha in carbo-metallic oil conversion
Inventor: MYERS GEORGE D
IPC: C10G11/00
Filed: 1982-03-17
Granted: 1987-11-05
Abstract: A process is disclosed for the production of high octane gasoline and/or other valuable lower molecular weight products from carbo-metallic oils. Examples include crude oil, topped crude, reduced crude, residua, the extract from solvent deasphalting and other heavy hydrocarbon fractions. These carbo-metallic oils contain quantities of coke precursors and heavy metal catalyst poisons substantially in excess of what is normally considered acceptable for Fluid Catalytic Cracking (FCC) and substantial amounts of sulfur, nitrogen and other troublesome components may also be present. Such carbo-metallic oils are converted to the desired products in a catalytic conversion process where the oil feed is mixed with naphtha and brought together with a high-metal content cracking catalyst. Named "RCC" (Reduced Crude Conversion) after a particularly common or useful carbometallic feed, the present process is by no means restricted to reduced crude or to oils of petroleum origin, having utility in the processing of oils from coal, shale and other sources.

Title: One-transistor memory cell for high-density integrated dynamic semiconductor memories, and method for manufacturing the same
Inventor: MULLER WOLFGANG DR
IPC: H01L27/108
Filed: 1984-12-07
Granted: 1989-04-13
Abstract: A one-transistor memory cell comprises a semiconductor body which has a thin insulating layer on a boundary surface and a conductive layer on the thin insulating layer, the conductive layer representing that electrode of a storage capacitor that is connected to a selection field effect transistor. The selection field effect transistor is realized in a layer applied as a polycrystalline semiconductor layer and is then recrystallized.

Abstract: Photoactive pyrite layers, whose preparation and use represent a commercially highly interesting alternative to materials hitherto in common use. The semiconductor material chiefly used until now, e.g. for solar cells, is silicon. However, its costs of manufacture are too high to allow solar cells to be made at favorable cost. The significance of the disclosure and development of pyrite as a semiconductor material, especially for solar cells, lies in the fact that it is plentifully occurring and cheap, as well as environmentally compatible. Pyrite (iron pyrites, FeS2) can be used as a photoactive material in solar cells and in optoelectronic components. It is possible to use both naturally occurring pyrite, after a material treatment to improve the photosensitivity, as well as synthetically produced, single-crystal and polycrystalline pyrite.
