Patent EP-0241648-A2 (EP)
Inventor: SULCER JAMES R JR
IPC: G04F10/04
Filed: 1987-01-29
Abstract: An electronic non-volatile elapsed time meter useful for generating elapsed time information when connected in parallel with an input supply voltage supplying power to a power driven device. Visual readouts are continuously generated during time of use of the input supply voltage and accumulated intervals of time of use are stored in a non-volatile memory when power is removed from the device. Upon a later resumption of power usage, the stored non-­volatile data is retrieved, displayed and summed with the new generated elapsed time information. This meter is applicable to both AC and DC operations.

Abstract: A retaining flange for the liquid-proof attachment of a radially outwardly projecting collar (2) to a sealing surface (3). The collar (2) is axially surrounded by two inwardly projecting supporting collars (4, 5) of the retaining flange and is sealed with respect to the supporting collars (4, 5) by means of two first O-rings (6). The supporting collar (4), arranged between the collar (2) and the sealing surface (3), consists of an annular disc (8) sunk into a recess (7) in the retaining flange (1). The annular disc (8) is bounded externally and the recess (7) internally in each case by a conical surface (9, 10), whose diameter reduces towards the opening. The two conical surfaces (9, 10) are at a distance from one another and are supported on one another by means of a second O-ring (11). The second O-ring (11) has a larger axial extent than the recess (7) and at the same time provides static sealing of the retaining flange (1) with respect to the sealing surface (3). <IMAGE>

Inventor: WOLZE DAVID A
IPC: H05B41/16
Filed: 1987-06-24
Abstract: An improved high power (40 000 watt) high intensity arc discharge power supply which provides reliable, automatic ignition control and enables precise variation of lamp power in dual AC and DC modes of operation over an extended dynamic range from 400 watts to 40 000 watts. A capacitive boost circuit is provided to supply the high voltage necessary to ignite the lamp. Upon start-up, the voltage on a boost circuit capacitor is monitored by an ignition circuit which automatically enables the ignitor when the voltage is at the required level and switches the ignitor off when the lamp starts. 
     After ignition the boost charging circuit is disabled and the power supply operates in a normal mode. The power supply operates on a three phase alternating voltage input through a three phase bridge, switches it through a drive transistor and then supplies it to an inductor. The signal is then supplied through an H-bridge commutator to the boost circuit, the ignitor and the arc lamp itself. The circuit operates under the control of an analog computer which determines the switching rate, monitors the voltage and current, provides power feedback and generally controls the power supply. 
     A power command input signal determines the power level at which the arc lamp will operate. Below a certain lamp current level, an oscillator circuit controlling the commutator is disabled so the lamp will operate on DC power in a «simmer» or low temperature mode. The lamp is thus operated over a large dynamic range.

Abstract: Multi-layer photoconductive elements comprising one or more layers of hydrogenated amorphous silicon are provided with sensitizing and supersensitizing layers which function to alter the spectral sensitivity of the element and thereby enhance its usefulness in such applications as photovoltaic devices, thin film electronic devices, and electrophotographic photoreceptors. The sensitizing layer contains a phthalocyanine which serves as a spectral sensitizing agent and the supersensitizing layer contains an arylamine which serves as a chemical sensitizing agent. The sensitizing and supersensitizing layers serve by their conjoint action to inject charge into the hydrogenated amorphous silicon layer in response to photogeneration within the sensitizing layer that is activated by radiation to which the hydrogenated amorphous silicon layer exhibits a lower degree of sensitivity.

Title: Method of manufacturing wafers of semiconductor Material
Inventor: MOFFATT ALEX P
IPC: C30B33/00
Filed: 1987-01-06
Abstract: A method of manufacturing wafers of semi­conductor material incorporates the steps of: providing an elongated ingot of semiconductor material having a curved surface along the direction of elongation; mounting a structure for ingot mounting on each of the end surfaces of the ingot; positioning the ingot mounting structures on fixture structures to mount the ingot; and rotating the mounted ingot. The positioned ingot mounting structures are released and the ingot is removed from the fixture structures; however, during the course of the process the mounting structures are again positioned on fixture structures to mount the ingot and the ingot is rotated a second time. The method is adapted for accurate centering of the ingot during processing involving the sawing of the ingot to provide opposed elongated planes therealong (including rotation of the ingot in accomplishing such) and involving further rotation of the ingot during grinding. The ingot mounting structures are centered on the basis of crystallographic node lines that appear on the grown ingot. The mounting structures have spherical surface portions for accuracy in centering the ingot in fixtures having conical surface portions to abut the spherical surfaces in mounting the ingot.

Abstract: A data base manager system operates a relational data are stored in a memory. The system sequentially generates a plurality of prompt screens on a display. Operator responses thereto, input at keyboard, define a query statement which, when executed by a processor retrieves a correlative data subset from the memory. The query is comprised of clauses. A plurality of sequential prompt screen-responses specify at least one of the clauses. Available valid response choices and/or response instructions displayed in a screen automatically appear and are varied as a function of response to the prior screen. In one embodiment, the left side, comparison operator, and right side of a row condition clause are each specified by at least one prompt screen-­response. When the left side or right side is complex including a summary function or expression, a sequential plurality of prompt screen-responses specifies the respective left or right side. The system enables a database user to specify complex query statements without knowledge of the syntax and semantics of the query language.
