摘要:
An infrared radiation gas analyzer for determining the concentration of an ingredient in a sample gas has a sample gas container for containing a sample gas at a temperature at which the ingredient the concentration of which is to be determined will emit infrared radiation in the range characteristic of the ingredient and a window for allowing the infrared radiation to escape from the container. An optical chopper outside said container interrupts the radiation escaping from the container. A pair of filters is positioned in the path of the radiation escaping from the container and spaced transversely of the path, one of the filters transmitting only radiation in the range and the other of the filters transmitting only radiation in a range near to the first mentioned range. Infrared radiation detectors are positioned for receiving the radiation passed by the respective filters and they emit a signal representative of the difference between the radiation received by the respective detectors and which is representative of the concentration of the ingredient the concentration of which is to be determined in the sample gas.

A destination inconsistency judgment apparatus, a destination inconsistency judgment method, and a medium recorded with a destination inconsistency judgment program are provided, in which a destination-information designating an information-exchange-destination is compared with a transmitter-information included in a transmitted exchangee-information, and it is judged that an inconsistency has occurred in the destination-information when the destination-information and transmitter-information are inconsistent with each other. Further, a destination inconsistency correction apparatus, a destination inconsistency correction method, and a medium recorded with a destination inconsistency correction program are provided, in which the transmitter-information is added, as the destination-information, when it is judged that an inconsistency has occurred in the destination-information.

An information transmission apparatus, an information transmission method, and a medium recorded with an information transmission program in a store-and-forward type of electronic conference system in which operational informations representing operations performed for various objects are stored in a queue and the stored operational informations are batch transmitted, wherein there are deleted the series of informations in the operational informations stored in the queue, which do not cause any resultant changes, so that the quantity of information exchange is reduced. The sequence of informations to be transmitted is also ensured, by skipping the destination for which a transmission error has occurred upon transmission of operational informations thereto.

A method of measuring microbial activity of microbes in real time includes preparing a medium to enable microbial activity and placing the medium in operative contact with an appropriate sensor. The sensor is scanned to provide measurement electrical signals representative of position and amount of microbial activity, the sensor being responsive to a by-product of the microbial activity, such as a change in pH. The measurement signals can then be processed to provide a visual image display, and the display can visually distinguish between levels of pH activity and coordinate positions of the microbial activity.
摘要:
A method of producing a pH-responsive membrane by coating a substrate with an anhydrous coating solution of tantalum alkoxide. In a first preferred embodiment, an anhydrous tantalum alkoxide solution is deposited drop by drop on a surface of an electrode substrate which is rapidly rotating to form a film of tantalum alkoxide. After drying to remove the solvent, the electrode is baked to decompose the tantalum alkoxide, thereby forming a pH-responsive membrane of tantalum pentoxide. The thickness of this membrane can be controlled by altering the speed of substrate rotation and the volume of coating solution deposited thereon. In a second preferred embodiment, an electrode substrate is immersed in an anhydrous coating solution of a tantalum alkoxide followed by pulling the electrode substrate from the solution at a controlled rate to form a tantalum alkoxide film which is then converted to a pH-responsive membrane of tantalum pentoxide by drying and baking.
