Map information systems now attract considerable attention as a new information processing system to cope with the diversification and rapid variation of society which store maps, drawings and relevant information in the data base. Fuji Electric has developed a map information operating system FAMOS to meet the requirements.
The FAMOS consists of basic software according to scales, i.e. MAPSTAR, MAPSKY and MAPWORLD, and specialized systems for each field, so that the construction of various system scales is possible. This paper describes an outline of the system organization and features of the FAMOS.

Processing systems for map and drawing information have recently come in wide use mainly in water treatment, electric power and local governments. Fuji Electric formerly commercialized various processing systems with FAMOS/MAPSTAR, MAPWORLD as basic software. Now it has developed FAMOS/MAPSKY, a medium scale software mainly for minicomputer use aiming at applying to more advanced function, high-performance processing systems, which is outlined in this paper.

In the period of maturity, the activities of enterprises and individuals diversify from cities outward and social needs for sophistication in urban environment are growing.
Responding to these needs, Fuji Electric has applied computer mapping systems to the fields of urban administration and systematized a group of systems now in the stage of practical use developed from work analysis.
This paper gives an outline of the urban information system on the points of (1) Concrete cases, (2) Functional organization, (3) Software, and (4) Hardware.

In the field of water treatment where buried pipe lines are dealt with, map information processing can be widely applied and there is a growing need for the system.
This paper introduces an outline of Fuji Electric's map information processing application to pipe line administration systems, its features, and the system configuration of a medium-scale system.

Equipment management in factories, plants, and laboratories has to deal with many kinds of cross-sectional information and requires efficient management and practical use of the drawings and ledgers of facilities and equipment. Various Functions of mapping systems can meet the requirements.
The paper introduces mapping system application to equipment management as one of its applications mainly from a operational point of view.

Distribution automation systems are rapidly put to practical use. It is particularly required that the system data should quickly and precisely grasped and transmitted intelligibly to operators when a failure occurs or maintenance work is done. For this purpose, distribution automation system have been developed going on to display the distribution network and network status superimposed on the street map on a CRT.
This paper introduces an outline of Fuji Electric's distribution automation system under development for Shikoku Electric Power Co., Inc. laying stress on its mapping system.

The pipe line network for city gas is expanding year after year and becoming complex by degrees. Akita City Gas Service Bureau has recorded the data of each gas pipe line location under ground and the date of laying for information management to prevent an accident due to excavation in civil works or corrosion for many years.
Fuji Electric has developed a system for reducing management work by unified processing of gas pipe line information with a personal computer. This system can process both maps and pipe line information, and was supplied to Akita City Gas Service Bureau, which is outlined in this paper.

To maintain and manage park facilities includes many works such as making, renewal, maintenance and reporting of park drawings and lots of relevant data.
Fuji Electric has developed and commercialized a park management system "MAP-PARK" aiming at improvement in the quality and efficiency of maintenance and management of parks and greens and at effective use of sccumulated data using a personal computer.
This paper introduces an outline of a park managemento system supplied to a Local government

There is particularly high need for map information processing systems in the field of water treatment. However, the main current consists in large- and medium-scale systems because of the high cost of introduction. This paper introduces an application of Fuji Electric's service water pipe line information system "MAP-LINE" as an example of a low-cost small-scale system.

An increase in number of nozzles and rotating speed is indispensable to boosting the specific speed of Pelton turbines. However, jet interference and resultant rapid decrease in turbine output blocks application of higher specific speed. Little investigation has been published so far to elucidate the jet interference by flow visualization. Our recent flow visualization test for the buckets and jets in a high-specific-speed 6-nozzle model Pelton turbine has made the jet interference phenomena clear and succeeded in taking their photographs. After studying how to cope with the jet interference, the limit of specific speed can be increased by more than 25%.

One of the problems in medium and small hydraulic generating plants is labor saving in maintenance and inspection. Therefore, generating units that need no water for cooling and others have been hoped for. Fuji Electric planned to enlarge the applicable scope of the cooling method with rotating heat pipes, made rotating models similar to actual units, and carried out verification tests for various improvements and devices. Thus an effective cooling method has been developed which is applicable to the horizontal Francis turbine generators of 5000 kW or less that account for the majority of medium and small ones. This paper describes the features of the construction and the result of the experiments.

This system has been developed to meet the needs for automation of transfer cranes in refuse incineration plants.
The paper introduces an outline of the refuse transfer facilities, working processes, system configuration and functions to meet the requirements of the automation system for refuse transfer cranes, three features (automation of various processes, automatic control system peculiar to refuse transfer cranes, and devices for the man-machine interface), the effects of introduction, and system evaluation.
