Abstract: A self-checking circuit and a method of its configuration are useful for achieving highly reliable system configuration.      A logic circuit having an error detection function has function blocks for feeding out a plurality of signals at least duplexed. The system compares the output signals of the function blocks and detects an error on the basis of the results of the comparison. A synthesizing system superimposes inherent waveforms assigned in advance to the respective output signals of the function blocks onto the output signals of one of the function blocks. The inherent waveforms are orthogonal waveforms generated by an orthogonal waveform generator circuit. The logic circuit also compares the signal output of the synthesizing system with the signal output of the other function block to detect the error. The whole circuit including the function blocks are judged normal only if waveforms inherent to both the output signals exist.

Abstract: A transceiver module for optical communication includes a light-emitting element, a light-receiving element and a rod lens. Light from the light-emitting element is condensed onto the top end of the rod lens. A ferrule of an optical fiber is brought into physical contact with the top end surface of the rod lens so as to couple the light-emitting element and the light-receiving element with the optical fiber. The rod lens is held by a support supported by a spring member on a housing, and the outer diameter of the rod lens is formed so as to be substantially equal to the outer diameter of the ferrule. An opening portion is provided in the housing so that the top end of the ferrule of the optical fiber is slidably fitted into one end of a sleeve, the other end of which is slidably fitted onto the outer circumference of the rod lens. Also, a transceiver module includes a light-emitting element for emitting transmission signal light, a coupling lens for connecting the transmission signal light emitted from the light-emitting element to a light transmission path, and a light-receiving element for receiving detection signal light from the light transmission path, in which the transmission signal light emitted from the light-emitting element is reflected on a surface of the light-receiving element and connected to the light transmission path through the coupling lens; and the detection signal light from the light transmission path is received by the light-receiving element.

Abstract: L'invention concerne un procédé et un appareil pour la déposition simultanée en phase gazeuse par procédé chimique et assistée au plasma d'un film mince sur une bande allongée d'un substrat sur plusieurs zones individuelles de déposition séparées dans l'espace (12). Afin d'effectuer ladite déposition simultanée, la bande de matière du substrat (10) est positionnée afin d'assumer un trajet en serpentin à travers une enceinte (1) à pression réduite. En utilisant un applicateur linéaire allongé (4) comme source d'énergie à micro-ondes, il est possible d'obtenir simultanément un taux élevé de déposition uniforme de matière du film mince sur une pluralité de grandes zones du matériau du substrat en bande sans devoir chauffer ladite bande à une température supérieure à son point de fusion. Dans un mode préférentiel de réalisation, la bande de matière de substrat est constituée d'une résine plastique synthétique de transmission des micro-ondes de basse température, et le film mince déposé sur la bande de substrat forme un revêtement-barrière qui empêche la diffusion d'oxygène.

Title: Filter media treatment of a fluid flow to remove colloidal matter
Inventor: COMSTOCK DANIEL L
IPC: B01D37/03
Filed: 1994-03-18
Granted: 2005-01-25
Abstract: Colloidal matter is removed from a fluid flow (122) by first adsorbing a coagulant (162) onto the surface of a finely divided filter media (126), and thereafter passing a colloid-containing fluid (122) through the filter media (126). The adsorbing of coagulant (162) is accomplished with the filter media (126) off line, and it is returned on-line for filtering of the fluid. After the coagulant (162) is adsorbed onto the filter media (126), it is not necessary to continue feeding coagulant during on-line operation, as the adsorbed coagulant captures the colloidal matter in the fluid (122) and retains it on the surface of the filter media (126). The captured colloidal matter is removed during back washing of the filter media (126).

Title: Fluorescent labeling complexes with large stokes' shifts formed by coupling together cyanine and other fluorochromes capable of resonance energy transfer
Inventor: WAGGONER ALAN S
IPC: C09B23/00
Filed: 1996-06-05
Granted: 2007-04-10
Abstract: The present invention provides low molecular weight fluorescent labelling complexes with large wavelength shifts between absorption of one dye in the complex and emission from another dye in the complex. These complexes can be used, for example, for multiparameter fluorescence cell analysis using a single excitation wavelength. The low molecular weight of the complex permits materials labelled with the complex to penetrate cell structures for use as probes. The labelling complexes are synthesised by covalently attaching through linkers to form donor-acceptor complexes. Resonance energy transfer from an excited donor to fluorescent acceptor provides wavelength shifts up to 300nm. The fluorescent labelling complexes preferably contain reactive groups for the labelling of functional groups on target compounds, such as derivatised oxy and deoxy polynucleic acids, antibodies, enzymes, lipids, carbohydrates, proteins and other materials. The complexes may contain functional groups permitting covalent reaction with materials containing reactive groups.
