Introduction service is supported, in order to activate and facilitate community activities. A community management centersearches for offered-service information that matches at least partly with an application designated by a coordinator terminal, and selects participants specified by detected offered-service information, as introduction candidates. Then, an introduction candidate list that describes private information, desired terms, and possessed value of ticket for each of the selected introduction candidates is displayed on a coordinator terminal. When the coordinator terminalselects a participant to be introduced to the applicant, out of the introduction candidates described in the introduction candidate list, then, the private information and the desired terms of selected participant is displayed on a participant terminalof the applicant.

Introduction support method and system, and introduction method and system

In a multiple computer system, a computer sends a program annexed with a code representative of the characteristic (e.g., the content and length of the program, the cooperation with other programs, the content of input and output data) of the program to the transmission line. Another computer checks the program based on the code representative of the program characteristic, and receives the program if necessary or executable based on the check result. Each computer can set, as occasion arises or if necessary, codes representative of the characteristics of several programs executable by the computer, so that specific receiving stations are not needed to be identified beforehand. The received program is checked based on the characteristic code annexed thereto, and if proper, the program is stored or executed if necessary.

An image correcting apparatus for correcting distortion appearing in an image produced by electron beam scanning in a SEM under the influence of electric, magnetic and mechanical vibrations through arithmetic operations for eliminating the distortion. Installation of electric shield, magnetic shield and vibration-damping structure is thus rendered unnecessary.

An autonomous resource management method for improving performance of a system in which plurality of process units compete for resources. Previously determined allocation policies are stored in memory along with system status data, control data and an evalution of the effectiveness of the allocation policy. During the operation of the system, the status is detected and an allocation policy is retrieved from memory based on the detected status. The allocation policy is then modified and sent to the scheduler. The effect of modifying the allocation policy is detected and an evaluation of the modified allocation policy is stored in memory. Inferior allocation policies are deleted from memory.

In order to make an accurate display possible even in case image data having been subjected to a Fourier transformation have negative values, the sampling timing deviations of measured signals having phase errors based on various factors are detected from the gradient of the linear components of the image data having been subjected to the Fourier transformation, and the density values of the image having the detected timing deviations corrected are displayed.

Nuclear magnetic resonance imaging method

A method of resource allocating to respective unit processes is disclosed which comprises, in order to allow the resource allocation based on experimental know-how of operation without assistance of a system operator, the steps of storing information of each unit processor including its priority, and names and functions of the resources required by that unit processor; storing information of each resource including an operation status and a process content of that resource; storing experimental know-how obtained in the operation of the system; and carrying out resource allocation to the unit processes in accordance with the stored experimental know-how when the operation status of the system corresponds to the stored experimental know-how and in the order of priorities of the unit processes as stored by taking reference to the stored information of each resource when the operation status of the system does not correspond to the stored experimental know-how, thereby improving the utilization efficiency of the resources.

Resource allocation method in a computer system

The structure of a circuit which is given basic net data is stored as a pattern, the compliance of the basic net data with the pattern is checked by the separately prepared search function, and upon fulfillment of compliance the pattern is determined to exist within the circuit. The subcircuit to be recognized by elements is not directly defined, but is defined using an intermediate expression defined recursively so as to implement a search through pattern matching. In another form, one input terminal is specified, which is followed by a search for blocks having the terminal as an input node and the search for blocks having one of the output node strings as an input node recursively and cyclically until the output terminal is reached, so as to extract a string of nodes on which the signal is propagated. The system is provided with functions for recognizing and comprehending subsidiary structures of the circuit which are not defined by the entered net data. By the combinational use of the recognition result and the layout shape generating function prepared separately, the layout shape of the subsidiary structures are determined. Shapes of objects determined through the above process are laid out automatically, while avoiding obstacles, within a predetermined space. According to still another form, layout patterns of variable structure memorizing the object layout and wiring affair are prepared in advance, and a layout plan for a circuit having a hierarchical structure is created through the operation of embedding the circuit to be laid out into a pattern.

In order to execute a series of operation sequence including synchronization and exclusion for an automatic machine such as a robot by combining pretaught or preprogrammed unit operations, there are provided first memory for storing a start sequence of the unit operations to be synchronized or excluded, second memory for storing operation status of the unit operations and third memory for storing operation command to start the unit operations. The unit operations to be started are determined by referring the start sequence and the operation status of the unit operations read from the memories, and the corresponding operation commands are read out of the third memory to squentially start the unit operations.

Method and apparatus for controlling an operation sequence of machinery

A control system employs a controller for controlling the operation of a plurality of facilities and a memory which stores information employed by the controller for controlling the operation of the facilities. The memory includes a first portion for storing facility status signals and command signals, a second portion which stores a series of rules which are triggered in response to status information from the respective facilities, a portion which converts the rules into internal codes, and a portion which stores the results of the application of the internal codes to control commands. The controller monitors facility status signals and controls the generation of facility status signals. It also controls which rule set number is to be used in accordance with information stored in memory and contains an internal code generator for generating the internal codes corresponding to generated facility status signals. The controller reads out rules from memory based upon the rule sets being employed and generates control command signals in accordance with data stored in memory. From these signals, command signals are generated for controlling the operation of the facilities.

Facilities control method

A multi-facility control system includes a controller and attendant memory. Stored in the memory are a plurality of rules, each of which includes a conditional portion representative of a condition to be examined and a conclusive portion describing action to be taken when the condition is satisfied. Also stored in memory is the current status of each facility, information representative of the tasks to be performed by the facilities and updated status information resulting from the satisfaction of the conditional parts of the rules. The controller monitors the status of the facilities and compares monitored status information with the conditional parts of the rules stored in memory. When rule conditions are satisfied, control instructions are generated which are employed to produce command signals that are coupled to the respective facilities for controlling the operations thereof.
