摘要:
A communication device relates a plurality of identification information to specifying information included in the identification information and manages them, and thereby enhances easiness of identifying and specifying of a device of the other party and usability of a connection with the device of the other party. The communication device has an identification information reception part (a radio transmission/reception part, a baseband part and a control part), a storage part (a data base part) and an information processing part (a control part). The identification information reception part receives the pieces of identification information concerning the device of the other party to be connected, and in the storage part the pieces of identification information which are received are stored. The information processing part stores the pieces of identification information, which are received, in the storage part, and retrieves the identification information from the storage part by receiving input of the specifying information out of the pieces of identification information, and relates a result of that retrieval to the specifying information and outputs them, or makes that output possible. By this, it is possible to use the pieces of identification information related to the specifying information for specifying of the device of the other party and connection with it.
摘要:
A generator which can prevent deterioration of the chilling performance and corrosion, and can provide a high degree of reliability and long service life is disclosed. The high-temperature generator comprises a combustion chamber for flowing a combustion gas therein, a first tube assembly and a second tube assembly provided in the combustion chamber each of which has a plurality of heat transfer tubes for containing liquid therein. The first tube assembly comprises a plurality of bare tubes and is arranged at an upstream of the second tube assembly. The second tube assembly comprises a plurality of finned tubes provided with fins on the outer surface thereof. The heat transfer tubes are arranged in a staggered manner in a direction of the combustion gas flow within each of the first tube assembly and the second tube assembly. The bare tubes and the finned tubes are arranged aligned to each other in a direction of the combustion gas flow at a boundary area between the first tube assembly and the second tube assembly.

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.
摘要:
In a refrigerator of a compression type or an absorption type, including a condenser and an evaporator, an apparatus for cleaning condenser tubes in which a cleaning brush movably mounted in each tube is moved through the tube by reversing a flow of cooling fluid therethrough so that the inner wall of the tube can be cleaned by the moving cleaning brush. Switching means switches from a temperature control means which controls refrigeration capacity depending upon temperature of a cooling and heating medium within the evaporator during the refrigeration operation, to control by pressure restriction means which restricts the pressure within the condenser to not exceed a predetermined value, before the flow of the cooling fluid in the tube is changed for cleaning the tube. When the inner pressure of the condenser is lowered at least by a fixed value from the predetermined value, the flow of cooling fluid may be changed within the condenser without changing from the temperature control to the pressure restriction control. Method for cleaning the condenser tubes of a refrigerator in this fashion is also provided.
