Abstract: An interrupt process distributing system, provided in a CPU board in a loose-coupled type multiprocessor system formed of a plurality of CPU boards and one I/O board which are interconnected through common mediation and interrupt busses. A CPU executes interrupt requests; a queue counter, connected to the CPU through an internal bus, counts the interrupt requests which are sent from the common bus to and queued in the CPU. An interrupt transfer control unit, connected to the CPU and the queue counter through the internal bus, counts the interrupt requests as received from the interrupt bus, compares the number of queued interrupts with the number of received interrupt requests, and transfers the received interrupt requests to the CPU when the number of the received interrupt requests exceeds the number of queued interrupt requests.

Abstract: In a watchdog timer circuit for a system having a central processing unit and a storage unit, a watchdog timer is provided, which counts up to a predetermined counter value and generates an alarm signal for the central processing unit when the predetermined counter value has been reached. A reset unit is connected to the watchdog timer to periodically reset the watchdog timer in response to a first reset signal generated by the central processing unit, so that the watchdog timer is reset to an initial state. A data comparing unit is coupled to the storage unit to detect whether or not the storage unit is accessible and output a second reset signal to the watchdog timer each time it is detected that the storage unit is accessible.

Abstract: An oxidizable substance and/or a reducible substance is removed from a liquid, such as a liquid industrial waste, by treating the liquid with a composite comprising a fluorine-containing organic cation exchanger and a metal oxide or hydroxide, supported on the cation exchanger. The metal of the metal oxide or hydroxide is selected from manganese and elements of group 1B and group 8 of the periodic table. This treatment is carried out, if required, in the presence of an oxidizing agent, or by using the composite which has previously been treated with an oxidizing agent.

Abstract: In a method and an apparatus for reading a color image wherein the color image is illuminated and scanned by light from a plurality of light sources having different spectral properties to read the color image on the basis of the reflected light therefrom, at least one light source of the light sources is kept turned on during the scanning operation of the color image, thereby eliminating any problems resulting from its after-glow; and at least one light source of the light sources other than that kept turned on is repeatedly turned on and off with a period corresponding to the period of the scanning operation so as to project the light from the single and plural light sources selected from the light sources, at least once respectively, upon the scanned portions of the color image. The color image is read by detecting colors on the scanned portions of the color image on the basis of levels of the light reflected from the color image.

Abstract: A method and apparatus for processing image signals in which image sensors produce an image signal of a specific color and an image signal of the complementary color from a color image of an original by means of filters. A white balancing correction is applied to these image signals by selectively adjusting at least one of the image signals so that the image signals are equal to one another for each picture element along the scanning direction, while a white area of the original or a reference area is being scanned. In a preferred embodiment, a digital signal representative of a specific color is obtained by attenuating the white balanced image signal of the specific color and comparing it to the white balanced image signal of the complementary color, whereby faithful color separation of the specific color is achieved.

Abstract: A shading correction device has a variable attenuator which is provided in the transmission line of the picture signal after photoelectric conversion by the original reader. For example, at the time of reading all white surface of the original at the beginning of the original scan the information level of each bit of the picture signal, i.e., the level of each picture element, is sequentially attenuated by the variable attenuator. In order to make the level of each picture element uniform, a data on how much attenuation is required, is generated for each picture element and loaded in a memory. The variable attenuator is adapted to be driven and controlled based on the data loaded in the memory at the time of reading the original in the subsequent scan.
