A decoding type select logic generating method includes the steps of listing on a group basis input signal names and output destination signal names contained in register transfer descriptions and control codes for commanding execution of the register transfers for each of the same input signal names and same output destination signal names, simplifying logics by replacing the control code having the hamming distance of one by a bit meaning "don't care" on the group basis, generating AND gates for the control codes and the input signal names in each of the groups having the same input signal name and combining the outputs of the AND gates, generating AND gates for the control codes in each group having the same output destination signal name and combining the outputs of the AND gates for each of the output destination signal names, and combining the outputs of the groups each having the same input signal name and the groups each having the same output destination signal name.

A road traffic control method is provided which can continue to maximize the number of vehicles allowed to run on a road and shorten time required for a vehicle to reach a destination, by preventing and relieving congestion. The method controls traffic of vehicles running on each of a plurality of parallel running roads. Each road is made connected at an interval of a predetermined distance, and at least one of the plurality of roads has a plurality of lanes. The method includes the steps of: detecting traffic of vehicles running in two counter directions on each road, at a position before at least one connected point of each of the plurality of roads; and changing ratio between the numbers of lanes of at least one of the plurality of roads, in accordance with the detected traffic of vehicles running in the two counter directions.

A symmetric type loop communication system having no master station, in which a plurality of control stations connected to a loop communication path each have a timer with its set time different from each other control station. The timer of a station is reset when a transmission right signal (GA signal) from another control station is received. On the other hand, a GA signal is sent out to another control station together with a message frame when the timer thereof has counted to a predetermined state.

A method of storing articles in a warehouse having a plurality of storage blocks arranged adjacent each other with each of the storage blocks having a plurality of spaced racks for storing articles and linearly extending aisles between the racks. The warehouse also includes article transfer apparatus arranged for movement in respective aisles to transfer articles relative to a given location within a respective storage block and a control arrangement for operating the article transfer apparatus in accordance with a predetermined mode to transfer articles relative to said storage blocks. The method of storing includes the steps of storing a plurality of different articles in the storage blocks with at least two different articles in each storage block, storing in a first storage block at least one and another different articles, storing in a second storage block at least one article common to the one different article in the first storage block and at least one additional different article, storing in a third and any succeeding storage block at least one article common to the at least one additional different article of the immediately preceding storage block and at least one further different article, and storing in the last storage block as the at least one further different article an article common to the another different article of the first storage block to form an imaginary loop of articles in the warehouse.

This invention relates to a method an apparatus for measuring traffic flows or in other words, the flows of vehicles, inside and near a crossing, and is directed to provide method and apparatus capable of extracting vehicles with a high level of accuracy.Overlap of vehicles can be avoided by setting the field of a camera not to a range from the inflow portion to the vicinity of center of the crossing, but to a range from the center to the vicinity of the outflow portion (151) of the crossing. Accordingly, accuracy of traffic flow measurement can be improved.

A graphic processor comprises an input device for inputting a command from an operator, a display device for displaying graphic data and a computer for preparing and correcting graphic data by a command input from the operator and for making display control of the display device. When the operator wants to know the content of the command that is executed, he instructs the command to the computer. A command name, a processing content and a figure as an object of processing are calculated from history data instructed from the computer. The figure as the object of processing, the command processing content and the relation of correspondence are symbolized and displayed on the display device. Furthermore, a parametric figure is also displayed visually on the display device.
