A plurality of operation units are connected to one another. The operation units include a processor, a buffer memory, and a data transfer control circuit connected between the processor and the buffer memory for controlling the data input-output with the buffer memories in the other of the operation units. The buffer memories and the data transfer control circuit are connected with one another by data buses, respectively.

The reasoning system by knowledge activation of the present invention stores shallow knowledge and deep knowledge in memories. The reasoning by the reasoning mechanism is executed using the shallow knowledge. In case of the shallow knowledge to be used in the reasoning is not stored, the deep knowledge is used in the execution of the reasoning. Based on the information which is obtained by the execution of the reasoning, shallow knowledge is newly acquired. The reasoning system by knowledge activation needs only a short time for reasoning. Even in the case where shallow knowledge which is necessary for fast reasoning is not stored, the execution of the reasoning is possible, and new shallow knowledge is easily obtainable.

A combustion control apparatus comprises a premix combustion burner requiring primary air, an injector disposed in a primary air passage and including a constricted section having a fixed diameter and length, an enlarged section communicating with the constricted section and a fuel injecting port disposed concentrically with the constricted section and in a predetermined region, and a pressure regulator disposed in a fuel feed passage communicating with the fuel injecting port, the arrangement being such that the pressure regulator is controlled so that the pressure difference between the outlet section of the pressure regulator and the inlet section of the injector may be within the fixed range of the pressure difference produced between the inlet and constricted sections of the injector on the basis of the amount of primary air at the time of the lowest input, thereby maintaining the ratio between the amounts of air and fuel at a constant value and securing combustion stability and high combustion efficiency. Particularly, the apparatus is characterized in that it is highly effective even if the fuel pressure and air pressure are low.

An ultrasonic fluid measurement instrument is capable of highly accurate fluid measurement. A measurement part is provided forming a plurality of split channels partitioned by partition boards halfway across a fluid channel, and at least a pair of ultrasonic transmitter-receivers for transmitting ultrasonic waves into the fluid flowing through the split channels and receiving ultrasonic waves that have passed through the fluid. Further, an arithmetic unit calculates the flow velocity and/or flow volume of the fluid according to the propagation time of the ultrasonic waves. The measurement part further includes an approach channel for preliminarily rectifying the fluid flowing to the split channels.

A flow meter includes a flow path through which a fluid flows; a pair of transceivers for sending and receiving an ultrasonic wave propagating across the flow path; and a flow calculation section for calculating a flow rate of the fluid flowing through the flow path based on a result of the ultrasonic wave being sent and received by the pair of transceivers. The flow path has an equal flow speed area in which the fluid flows at a substantially equal flow speed over an entire flow rate area ranging from a high flow rate area to a low flow rate area. The pair of transceivers send and receive the ultrasonic wave so that the ultrasonic wave propagates in the equal flow speed area.

A pointer remotely points a display screen of a large screen display device. The display screen is picked up by a monitor camera. An image processing unit extracts a feature of the pointer used for pointing based on the resulting image signal to identify the position of the pointing point and the pointer based on the feature. A computer generates information on an object to be displayed at a position pointed by the pointer. The generated information is displayed on a display device (CRT display device or large screen display device) assigned to the pointer. Even when a plurality of pointers are used, the information on the object to be displayed pointed by the pointer is properly displayed.

A hot-water and cold-water mixing device is provided wherein a hot-water side valve element and a cold-water side valve element are provided for regulating the respective flow rates of hot and cold water flows. The valve elements are constructed so as to possess a temperature regulating function exercised by varying the hot-water to cold-water mixing ratio depending on a biasing force, and also an automatic pressure regulating function to automatically accommodate any sudden pressure changes. The water mixing device of the foregoing construction is compact in size and is capable of adjusting the final water temperature reliably and speedily.
