Patent EP-0677983-A2 (EP)
Inventor: ALLISON JOSEPH MICHAEL
IPC: H05B41/392
Filed: 1995-03-20
Abstract: Disclosed is a ballast circuit for a high pressure gas discharge lamp, including a comparator circuit for producing a feedback error signal representing the difference between a feedback signal and a reference signal. The feedback signal is selectively one of a non-light feedback signal and a light feedback signal, as determined by a switching circuit. A power control circuit adjusts the level of power supplied to the lamp in response to the feedback error signal. A first, non-light feedback circuit supplies a non-light feedback signal to the comparator circuit, based on non-light information of the lamp that is fed back to the non-light feedback circuit. A light feedback circuit operative during a lamp warm-up period supplies a light feedback signal to the comparator circuit based on light intensity information that is fed back to the light feedback circuit. The light feedback circuit has an adjustable gain as determined by the difference between measured light intensity and magnitude of the light feedback signal produced. A calibration circuit, operative during steady state lamp operation when the comparator circuit is responsive to the non-light feedback signal, automatically adjusts the gain of the light feedback circuit until a state is reached in which switching to light feedback control would result in substantially no change in light intensity. The calibration circuit includes a calibration memory for storing the gain for use in a subsequent period of lamp warm-up.

Abstract: A transmitter/receiver interface (12) for use with a bi-directional transmission path (18) couples a transmitter (14) and a receiver (16) to the bi-directional transmission path (18). The transmitter/receiver interface (12) separates transmitted signals (20) and received signals (22) and routes them from the transmitter (14) and to the receiver (16) with negligible interference. The transmitter/receiver interface (12) incorporates coupling elements (44 and 50) that couple the transmitter to the transmission path and incorporates networks that couple the receiver to the transmission path. Impedances of the networks are derived based on the coupling elements and the transfer characteristics of the transmission path to provide consistent attenuation of the transmit signal over a large frequency range.

Abstract: A paste-like ink is prepared by dissolving camphor in an alcoholic solvent and dispersing fine carbon particles with a catalyst carried thereon in the solvent (step S100). A sheet-like electrode-forming member is formed on an electrolyte membrane by screen printing the paste-like ink thus obtained (step S102). The electrode-forming member is dried at 80°C for one hour, in order to deposit camphor included in the electrode-forming member as a pore-forming agent (step S104). The electrode-forming member and the electrolyte membrane are joined with each other by hot pressing (step S106). The joint body of the electrode-forming member and the electrolyte membrane is dried under vacuum at 80°C for three hours, in order to sublimate and remove camphor depositing in the electrode-forming member (step S108). This gives an electricity-generating layer that is a joint body of an electrode having a plurality of pores and the electrolyte membrane. The manufacturing process of the invention thus gives a joint body of an electrode having sufficient gas permeability and electrical conductivity and an electrolyte membrane.

The cathode current collectors is connected to each other at ends disposed opposite to the anode current terminal to form ⊐ shape, and the cathode current collector is formed at a connection point as a cathode current terminal. The above mentioned molten carbonate fuel cell makes it no longer necessary to use a separator for mechanically separating anode and cathode gases, resulting in remarkable cost down.

Abstract: In the improved thermal recording method in which image data supplied from an image data supply source are subjected to specified image processing jobs and in which a thermal head is driven in accordance with the processed image data so as to perform thermal recording, image processing jobs are performed in a specified order such that sharpness correction and tone correction are followed by shading correction and correction of resistance values which, in turn are followed by compensation for temperature elevation, provided that calculation treatment of respective values of the image data for the compensation for temperature elevation is performed either prior to or after either one of the corrections that are performed subsequent to the tone correction. It is preferred that black ratio correction and/or load variation correction are also performed after the shading correction and the correction of resistance values, and prior to the compensation for temperature elevation. The improved thermal recording apparatus is used to carry out the thermal recording method described above. According to these apparatus and method, high quality images can be recorded consistently. <IMAGE>

Abstract: Human interferon-beta 2A  and interferon-beta 2B  are produced in purified
form by recombinant DNA techniques. Two separate human genes have
been identified which code for the production of IFN-β 2A  and IFN-β 2B ,
respectively. The sequence of IFN-β 2A  cDNA is established. These
genes and cDNA have been cloned into mammalian cells with an SV40
early promoter sequence and such genomic clones are capable of producing
IFN-β 2A  and IFN-β 2B . The antiviral activity of such
recombinant IFN-β 2A  and IFN-β 2B  is demonstrated as well as other
biological activity identifying them as human interferons. It has been
shown that IFN-β 2  secretion is induced in human cells by growth-stimulatory
cytokines. 
     IFN-β 2A  may be used as a medicament for influencing cell growth and differentiation.
IFN-β 2A  may also be useful during terminal differentiation of cancer cells.
