Patent EP-0141026-A3 (EP)
Title: Self-closing valve
IPC: E03D3/04
Filed: 1984-06-22
Abstract: A self closing valve has a housing with a water inlet and outlet and with a valve piston positioned inside it in such a way that the end of the piston facing away from the valve seat demarcates a discharge chamber in conjunction with the inlet and outlet through flowthrough passages that are activated in opposite directions by supplementary-valve controls in such a way that the duration of operation is determined by a decelerated opening stroke of the valve piston and closure is activated by a rapid closing stroke of the valve piston. The initiating position of the supplementary-valve controls that is provided during the opening activation of the valve piston is designed to maintain itself hydraulically as the result of a pressure difference generated at a choking device as the result of the flow through the valve and discontinuing the automatic maintenance shifts the supplementary-valve controls. Any leakage flows that may occur at the self-maintaining members are diverted to the outlet, without being choked off, through the supplementary valve that is opened by means of the initiating position of the supplementary-valve controls and the supplementary valve closes once self-maintenance and the shift in the supplementary-valve controls that is provided thereby have been discontinued, eliminating any potential bypass flow parallel to the flow through the choking device on the part of the flow through the valve.

lease characteristics between the adhesive and film.
Patent EP-0130768-A3 (EP)
IPC: H01L31/04
Filed: 1984-06-25
Abstract: The invention concerns an external issolation module (42) 
adapted to operatively interconnect at least one pair of a plural­
ity of adjacent vacuum chambers (28, 30) through which a 
substrate (11) travels and into which reaction materials are 
introduced. The external isolation module (42) provides a 
passageway (44) for the substrate (11) between adjacent 
chambers while substantially preventing the diffusion of reac­
tion materials from one of the chambers into the adjacent 
chamber. An accessible, environmentally-sealed, reaction ma­
terial-isolating passageway is thereby formed.

Title: Phase reading fiber optic interferometer
IPC: G01C19/72
Filed: 1985-04-16
Abstract: A system and method for detecting the influence of selected forces on an interferometer over an extended dynamic range. One presently preferred embodiment is disclosed for detecting rotation of an interferometer. In this embodiment, an open-loop (14), all-fiber-optic gyroscope provides an output signal comprising the phase difference of two light waves which are counterpropagating within the gyroscope, and which are phase modulated (38) at a selected frequency. The phase difference of the light waves is influenced by the rotation rate of the interferometer. The output signal is amplitude modulated (156, 300) at the phase modulation frequency to transpose the optical phase shift into a low frequency electronic phase shift, which is measured using a digital time interval counter (166, 168, 174, 178, 304, 308). A linear scale factor is achieved through use of this system and method.

IPC: H05G2/00
Filed: 1986-04-22
Abstract: An X-ray tube has a wide area cold cathode (25) with a 
graphite felt surface (21) which faces and is spaced from a 
wide area anode (50) of high atomic number material. A grid 
(60) is interposed between the two and the anode, grid and 
cathode are enclosed in an envelope (25) which is filled with 
gas at a low pressure. The graphite surface (21) of the 
cathode (25) is connected to a relatively high negative 
potential so that electrons are emitted from the entire surface 
area and impinge upon the anode (50), after triggering by the 
grid (60). The distribution of the energy of photons emitted 
from the anode is relatively constant during the ignition 
period of the tube. An extremely wide area X-ray source is 
then defined having constant bremstrahlung content which 
enables good gray scale measurements when employing the 
X-ray source. A pinhole collimator (51) disposed externally of 
the tube ensures collimation of the output X-ray field. A 
polarized electron beam (120,121) is used as a collimator in 
place of the pinhole collimator, in a preferred embodiment, 
to produce a collimated, wide area X-ray flux. The cathode, 
grid and anode structure can have any desired size or shape. 
The X-ray source can be flat and sized to illuminate a chest 
X-ray film or can be arcuate to at least partly wrap around the 
subject to be exposed to the X-rays. Arcuate X-ray sources 
can be linked end to end and scanned sequentially to define 
an X-ray source for use in Computer Axial Tomography 
(CAT) scan type applications. The same computer alogrithm 
used for conventional CAT scan analysis can be used.

Abstract: A reversible fragrance emitting unit adapted to rest on a 
table or other flat surface in either an upright position in 
which the rate of fragrance emission is low, or in an upside 
down position in which the emission rate is high, the unit 
having the same attractive outward appearance in either 
state. The unit consists of a fenestrated open-ended shell 
having a decorative form whose inlet and outlet ends are 
attached to inlet and outlet boxes of like dimensions, both 
having bottom walls. The inlet box has an open top, whereas 
the outlet box is closed by a top wall to define an internal 
chamber which extends through the shell between the 
bottom wall of the inlet box and the top wall of the outlet 
box. The chamber contains a charge of fragrance-emitting 
pellets in an amount sufficient to almost fill the inlet box 
when the unit is placed in its upright position in which the 
inlet box rests on the table and the pellets are confined 
within the inlet box and therefore emit relatively little 
fragrance, the unit being effectively "off". When, however, 
the unit is reversed to occupy its upside down position in 
which the outlet box rests on the table, the pellets then 
ooccupy the shell and emit fragrance through the openings 
therein at a much greater rate and the unit is "on".

Abstract: To locate the upper surface of an object (18) on a substrate 
(20), a first real image of a Ronchi ruling (parallel bars) (22) is 
projected by an objective lens (16) and moved into coincidence 
with the upper surface by vertical movement of a video camera 
(10) to which the ruling (22) and lens (16) are fixed. The video 
camera sensor (12) performs line scanning perpendicular to the 
bars of a second real image of the ruling (22) formed by the 
lens (16) projecting light reflected up by the upper surface. 
Accurate coincidence of the first real image with the upper 
surface provides a camera output signal containing a strong 
component at a frequency determined by the spatial frequency 
of the image scanned and the line scan frequency. Measure­
ment of the vertical position of the camera (10) and sensing 
of several surface provides signals which can be digitally 
processed to give data on the structure of, for example, a small 
manufactured article.

Title: Integrated circuit comprising bipolar and complementary mos transistors on a common substrate, and production method
IPC: H01L27/06
Filed: 1987-03-26
Abstract: In an integrated circuit comprising bipolar (A) and complimentary MOS transistors (B, C) in which the base and emitter terminals (37, 38) of the bipolar transistor (A) and the gate electrodes (35, 36) of the MOS transistors (B, C) consist of a silicide or of a double layer of polysilicon (32)/silicide (33), the base and emitter terminals (37, 38) and the gate electrodes (35, 36) are arranged in one level of the circuit and their p<+> or n<+> doping takes place as a result of ion implantation in the production of the source/drain regions (40, 41) of the MOS transistors. Because of the alignment-independent spacing of the emitter contact (38) from the base contact (37), the base spreading resistance is kept small and a further reduction in the space requirement is achieved. The use of polycide or silicide as diffusion source and as terminal for the emitter makes smaller emitter widths possible. The size of the bipolar transistor (A) is not limited by the metallisation pattern since contact can be made to the silicide terminals (37, 38) via the field oxide (24). The integrated semiconductor circuit is used in VLSI circuits having high switching speeds.

celeration to deenergize an electrically actuated fuel 
injector (16) to interrupt fuel supply to the engine 
when a throttle valve (14) is in closed idle position

r.p.m. level. When it is detected by the control 
unit (32) that the throttle valve (14) is still in the 
idle position and the engine speed has been lowered 
to a second predetermined r.p.m. level lower than the 
first predetermined level, the control unit operates to 
resume the fuel supply at a rate increased compared with 
engine intake air flow rate and engine speed both detec­
ted at this time, and, simultaneously, retard the 
ignition timing whereby the engine speed smoothly 
and gradually varies after the resumption of fuel supply.
