Abstract: The object of the present invention provides an evaluation system for evaluating accurately emission amount of environmental influence substance of fuel in a fuel supply facility for supplying stored fuel to a consumer. An evaluation system evaluates the emission amount of environmental influence substance of fuel in which the environmental properties (greenhouse gas emissions) accumulated in the process of drilling a first energy, transporting and storing, producing fuel, and supplying the fuel are taken into account. The evaluation system enables to present the environmental properties of the sold fuel to the fuel consumer and allows the fuel consumer to select, thereby promoting the reduction of emission amount of the greenhouse gas of the fuel supplier and the fuel consumer.

Abstract: A power semiconductor module with its thermal resistance and overall size reduced. Insulating substrates with electrode metal layers disposed thereon are joined to both the surfaces of a power semiconductor chip by using, for example, soldering. Metal layers are disposed also on the reverse surfaces of the insulating substrates and the metal layers are joined to the heat spreaders by using brazing. Heat radiating fins are provided on the heat radiating surface of at least one of the heat spreaders. The heat radiating side of each of the heat spreaders is covered by a casing to form a refrigerant chamber through which refrigerant flows to remove heat transmitted from the semiconductor chip to the heat spreader.

Abstract: In a conventional hybrid scheme used to mount a rechargeable battery in a motor vehicle, store into the battery the electric power that has been obtained via a regenerative brake, and utilize the power during acceleration of the vehicle, when a temperature rise of the battery due to charging or discharging causes a temperature of the battery to stay outside a defined range, it has been absolutely necessary to stop the battery charge or discharge, and fuel efficiency has decreased. This invention predicts a charge level and temperature of a rechargeable battery from the cruising input/output power requirements calculated from route information and historical records of cruising, prevents a stoppage of the battery by calculating chronological engine output and brake control data for the temperature to stay within a defined range, and hence improves fuel efficiency.

Abstract: In a refrigerant cycle apparatus, an energy-saving operation is performed by using a refrigerant which is used in a supercritical state. A refrigeration cycle apparatus is constituted by a main compressor, an expander, a sub compressor independently placed in an upstream side of the main compressor, a use side heat exchanger, a heat source side heat exchanger and the like. A refrigerant such as a carbon dioxide or the like which is used in a supercritical state is employed as the refrigerant. The sub compressor is driven by utilizing a recovered energy by the expanding device. Further, a refrigerant tank is provided, and properly controls an amount of the refrigerant circulating in the refrigerant cycle.

Abstract: The present invention relates to air conditioning systems and more particularly to an air conditioning system which provides air conditioning in each of a plurality of spaces. The air conditioning system according to the present invention divides a space with partitions into a plurality of air conditioning spaces and controls the temperature by cooling and heating mediums supplied from an external heat source using a three-way valve and an expansion valve. The air conditioning system includes an ID card for identifying a person which uses the air conditioning system. If a person is present to use the air conditioning system, the set or measured values of the environmental conditions for that person is stored. When that person again uses the air conditioning system, the system calculates the environmental conditions stored by the person in accordance with his stored set or measured environmental condition values.
