摘要:
A display device or method for an operating procedure which enables an accurate transmission of an operating procedure of a target element to an operator, which enables the operator to understand the operating procedure promptly and rationally and which enables the operator to look at functional elements on the screen from a desired direction by the operation of the operator. Three-dimensional dynamic scene information is exploded based on three-dimensional scene information of mono-elements and three-dimensional procedure information which shows the handling procedure of functional elements. The three-dimensional scene information is structured by coordinates information of a desired reciprocal viewpoint and is displayed as exploded three-dimensional graphics in the display device. The coordinates information of a desired reciprocal viewpoint signifies a locus of time or a sequence of a variable which shows a reciprocal position and direction between an object and a viewpoint, and signifies time-series data of coordinates information which is suitable for showing the operating procedure.

In a plant for which process control is made, a margin of an operation allowable limit for a process variable is variably established according to situations for each apparatus constituting the plant. In addition, allowable upper limits of operation considering a life consumption state and an operation schedule of each apparatus are established for respective apparatus on the basis of a life of the whole plant. The life of each apparatus and the life of the whole plant are controlled with a goal to expire all equipment substantially at the same time by reflecting the allowable operating conditions of the apparatus constituting the plant on the plant control. Therefore, it is possible to realize rational and useful plant operation.

Described is a processing system for knowledge data base in which indices representing the degrees of certainty of causal relations between an event and plural events relevant to the first-mentioned event are stored. The system has an input unit for inputting information on those actually experienced among events inferred based on the knowledge data base, an updating unit for updating the indices so that, among the plural causal relations, the certainty of the causal relation corresponding to the actually experienced event inputted by the input means is made higher relative to the certainties of the other causal relations, and a storing unit for storing back the thus-updated indices again in the knowledge data base. This allows an expert system with the processing system to perform inference with higher certainty.

A consumer load receiving power from a power system is divided into a first load to which power may be interrupted if necessary to reduce demand on the power system, and a second load to which power supply may not be interrupted to reduce demand on the power system. When it is necessary to reduce demand on the power system, the power system sends a load control signal to a controller at the consumer indicating that supply of power to the first load is to be interrupted. In response to the load control signal, the controller interrupts supply of power from the power system to the first load, thereby reducing demand on the power system.

A four-stroke cycle engine unit for a working machine, for example, generally a valve drive mechanism for driving the exhaust and intake valves. The valve drive mechanism comprises a crank cam assembly mounted to a crank shaft of the engine unit so as to be rotated in accordance with rotation of the crank shaft, a cam gear assembly mounted on the cam shaft and meshed with the crank cam assembly, a cam assembly mounted onto the cam gear assembly so as to be rotated in accordance with rotation of the cam gear assembly, a pair of first and second lifters mounted on a lifter axis portion positioned in parallel to the crank shaft, the lifters being rocked in accordance with rotation of the cam assembly, a pair of first and second push rods lifted up and lowered in accordance with rocking motions of the first and second lifters, respectively, and a pair of first and second rocker arms operated in association with the first and second push rods. The lifter axis portion and the cam shaft are positioned in a plane including the crank and a center line of a cylinder of a piston-cylinder assembly of the engine unit. The first rocker arm is connected to the exhaust valve so as to carry out open-close operation thereof and the second rocker arm is connected to the intake valve so as to carry out open-close operation thereof.

A four-stroke cycle engine unit for a working machine has generally a lubricating device for lubricating mechanical parts in a valve chamber and a cam chamber. The lubricating device comprises a body which has the cam chamber and a crank chamber, a cylinder head and a head cover having the valve chamber, and a mechanism for preventing a lubricating oil from escaping from at least one of through holes for push rods provided in a wall of the valve chamber and the cam chamber.
