Patent EP-0385079-A2 (EP)
Inventor: DUVENECK UWE DIPL-ING
IPC: G02B27/64
Filed: 1990-01-18
Abstract: A viewing system, such as a telescopic sight or panoramic periscope for combat vehicles, has at least one optical system with a line of sight which passes through a viewing opening and is stabilised in a manner fixed in space. Arranged between the viewing opening and optical system is a swivellable viewing mirror for deflecting the light bundle incident through the viewing opening to the optical system, and a reflecting telescope with a Cassegrainian focus which focuses the light bundle onto the optical system. In order to achieve a small viewing mirror of slight extent and low moment of inertia, the two mirrors (concave and convex mirrors) of the reflecting telescope are arranged in a coaxial, fixed alignment with respect to the line of sight in front of and behind the viewing mirror. The stabilisation device provided to stabilise the line of sight acts on the mutually fixed alignment of the telescope mirrors, while the swivelling movement of the viewing mirror is derived via 2:1 reduction gearing of the vertical adjustment of the telescope mirrors. <IMAGE>

Abstract: A method of etching polyimide material having metal­lization patterned thereon in which an epoxy resin system not only provides the etch mask for etching the polyimide but also provides a resulting passivation structure overlying the metallization on the polyimide substrate. The polyimide having a desired metalliza­tion pattern thereon is coated with the epoxy based photoimageable material which has the properties of resisting concentrated KOH etching when the epoxy material is cured and also the property of adhering to the polyimide substrate and the metallized pattern after exposure to the KOH etch to provide a pas­sivation to the metallization. The process includes exposing the layer of photoimageable material to actinic radiation to selectively pattern the material, developing the patterned material to reveal the underlying polyimide to be etched, curing the re­maining material and etching the revealed polyimide material in concentrated KOH to remove the revealed polyimide. The remaining epoxy material is firmly adherent as a passivation layer for the metallization. Preferably the epoxy material consists essentially of from about 10% to about 80% by weight of a polyol resin which is a condensation product of epichloro­hydrin and bisphenol A having a molecular weight of between about 40,000 to 130,000, and between about 20% and 90% by weight of an epoxidized octafunctional bisphenol A formaldehyde novolak resin, having a molecular weight of between 4,000 to 10,000 and about   0.1 to about 15 parts by weight of resin of a cationic photoinitiator capable of initiating polymerization of the epoxidized resin system upon exposure to actinic radiation. The resin may optionally contain up to about 50% by weight of epoxidized di-glycidal ether of tetrabromo bisphenol A having a molecular weight of between about 600 and 2,500, if flame retardancy is required.

Abstract: A musical tone synthesizing apparatus which synthesizes a musical tone signal in response to the wind instrument, brass instrument and the like provides an excitation circuit (102) and a resonance circuit (103). The excitation circuit simulates the operations of the reed, mouth-piece and the like, while the resonance circuit which operates as the bi-­directional transmission path simulates the resonance tube. The excitation signal generated from the excitation circuit is transmitted through the resonance circuit consisting of delay circuits and junction circuits. Thereafter, the transmitted signal is reflected by the terminal portion, and the reflected signal is transmitted through the resonance circuit and then fed back to the excitation circuit. Thus, the excitation signal is circulated in the loop consisting of the excitation circuit and resonance circuit. Based on the signal picked up from this loop, it is possible to obtain the synthesized musical tone signal which simulates the wind instrument tone and the like.

Abstract: An EEPROM memory device having dual EEPROM transistor blocks for storing a charge and a current mirror for determining the difference in charge between the EEPROM transistor blocks. During a write operation, one EEPROM transistor block is charged while the other block is discharged. During a read operation, the current mirror attempts to supply equal current to each of the EEPROM transistor blocks. However, because each block has a different charge, more current will be forced through one leg of the current mirror. This results in a voltage difference across the legs of the current mirror which can be read by a voltage sensor.

Abstract: Disclosed are the N,N′-(1-oxo-1,2-ethanediyl)-bisaspartates, methods for their preparation (including an unexpected preparation from glyoxal bisulfite and aspartic acid in concentrated aqueous alkaline media) and useful compositions containing the same; illustrative are general-purpose sequestrant compositions, chelating agent compositions for transition metals such as iron,manganese and copper, general-purpose laundry detergent compositions and detergent compositions comprising perborate bleach, a bleach activator and, as a bleach stabilizer/performance enhancer, the novel bisaspartates. These unique nonphosphorus compounds are useful at low levels and differ from traditional -N-C-C-N- chelating agents such as ethylenediaminetetraacetates by the presence of one amino- and one amido- functional group which it is believed will provide additional advantages, such as improved biodegradation.

Abstract: A nuclear reactor complex (100) includes fusible plugs (112) to prevent water from a wetwell (120) from flowing into a drywell (106) including the reaction vessel (102). In case the core overheats and molten corium falls to the drywell floor, the heat from the corium melts the fusible plugs and water floods the drywell. The water inhibits a corium-concrete reaction, minimizing pressure increase within the drywell and thus the chances of radioactive materials being released into the environment.

Abstract: A scanner is operative with an imaging system for inducing a mechanical movement of a subject during an optical scanning of the subject to provide an image of the subject. The subject which is in the shape of a card is advanced along a travel path past an optical viewing site by means of a drum, the scanner including a first roller and a second roller which urge the subject against the drum. Initially, the first roller is located between the viewing site and the entry port for receipt of the subject in a first nip between the first roller and the drum. The second roller is positioned fixed on the opposite side of the viewing site. The first roller is supported by an arm which swings about a rotational axis of the drum to vary the spacing between the two rollers. Upon rotation of the drum in a forward direction for induction of the subject, a brake located between the drum and the arm drags the arm and the first roller towards the second roller to facilitate a transference of a leading edge of the subject from the first nip to a second nip defined by the second roller and the drum. Preparatory to optical scanning of the subject which is accomplished during reverse rotation of the drum, the arm swings the first roller away from the second roller to present the viewing site to the optical scanning beam.

Abstract: The invention provides an apparatus for developing and fixing a silver salt photosensitive material. The apparatus uniformly applies a fixed amount of new or unused processing solution onto the photosensitive material so as to maintain processing quality and reduce a required volume of the processing solution and labor for maintenance. 
     New or unused developer supplied from a developer nozzle 82 and temporarily stored in a basin 143 is uniformly held in pores on the surface of a developer applying roller 93. While the developer applying roller 93 is rotated, the new developer held in the pores of the roller 93 is applied onto the surface of a photosensitive material PM, which is pressed against the circumference of the roller 93 during conveyance, to develop the photosensitive material PM. The apparatus of the invention develops the photosensitive material with new developer applied to the roller 93 and thereby maintains processing quality even when a large number of photosensitive materials PM are processed. Furthermore, the invention does not require troublesome discharge or replacement of processing solution, which is generally carried out after processing of a certain number, thus saving time and labor. The processing method of the invention also reduces a required volume of processing solution.
