A data display system () and a patent map forming system () give evaluation values obtained by a predetermined evaluation axis or an arbitrarily set evaluation value in cooperation with each other, and forms a map sheet (MS) on the basis of the evaluation values. The data display system () acquires a first-class identification code such as a publication number from a basic data sheet (DS) obtained by listing bibliographical information or the like of a patent input by a spreadsheet software () from an input file, and an identification code conversion unit converts () the first-class identification code into a second-class identification code. A patent data server (SV) is directly accessed by the second-class identification code to read an abstract, a representative drawing, all documents, drawings, and the like, serving as detailed data, thereby displaying these data on a display (DP).

Data map forming system and method of forming a data map based on evaluation values

The cooling circuit of an internal combustion engine cooling system wherein the coolant is allowed to boil and the vapor used as a vehicle for removing heat from said engine is equipped with an external reservoir and arranged so that the amount of liquid coolant in the cooling circuit of the system can be varied in a manner which both assists in controlling the boiling point of the coolant and prevents the development of negative pressures which invite the invasion of non-condensible matter such as atmospheric air.

Cooling system for automotive engine or the like

In order to improve engine warm-up characteristics under cold climatic conditions and to safegard against possible unintentional overfilling of the of the cooling circuit of an evaporative type automotive cooling system wherein the coolant is permitted to boil and the vapor used as a vehicle for removing heat from the engine, the ambient temperature or a parameter which varies with the same is sensed and the control of the cooling system modified accordingly. One main feature comes in the control which is effected to reduce the surface area of the radiator of the system in which the coolant vapor is condensed is modified to avoid overfilling and possible damage due to overpressurization.

Cooling system for automotive engine or the like including quick cold

In order to minimize the number of valves and conduits and the amount of coolant must be carried in an auxiliary reservoir of an evaporative type automotive cooling system, the valve and conduit arrangement which communicates the normally closed circuit cooling system with the reservoir consists of only two conduits and two valves. When the engine is stopped the cooling circuit is allowed to fill completely with the coolant from the reservoir. When the engine is started a low temperature non-condensible matter purge operation is avoided and if the temperature rises above a target value, either coolant is pumped out of the system (if excess coolant is available therein) or high temperature vapor is vented from the bottom of the radiator in bursts to purge out the non-condensible matter.
