Abstract: Provided is a construction machine including an electrical component and efficiently cooling it. The construction machine includes an upper slewing body having an air intake chamber capable of taking in air, an engine, the electrical component, an air intake duct guiding the air inside the air intake chamber toward the engine, a blow fan directing the air inside the air intake chamber toward the engine through the air intake duct, and electrical-component cover covering the electrical component. The electrical-component cover defines an air flow path for flowing air along the electrical component, between the electrical-component cover and the electrical component thereinside. The electrical-component cover includes an air inlet communicating an upstream portion of the air flow path with the air intake chamber and an air outlet communicating a downstream portion of the air intake chamber with the air intake duct.

Abstract: A chart recorder apparatus wherein information is indicated by using light emitting devices which are disposed to access the rear surface of a chart on which measured signals of a chart recorder are recorded on a front surface thereof. Various types of information are projected and indicated without otherwise compromising features of a chart recorder and thereby enhancing functionality of a compact chart recorder having a small display area.

Abstract: A transaction intermediary apparatus, system and method with a negotiation capability promote trade of goods or services between buyers and sellers for achieving buyer driven transactions including transactions resulted from negotiation requests initiated by buyers. The apparatus receives first and second offer data of goods or services provided by sellers where the second offer data has conditions more beneficial to buyers in price or quality than that of the first offer data. The apparatus receives purchase conditions requested by a buyer and offers, in response, the first offer data to the buyer, receives a negotiation request from the buyer, and offers the second offer data in response to the negotiation request.

Abstract: A vacuum furnace for brazing aluminum with brazing metal containing magnesium in which evaporated magnesium in the furnace is oxidized before aluminum members having been brazed are taken out, and/or the temperatures of a movable wall serving to control the communication between a vacuum pump and a heating chamber during heating and of an inner surface of the heating chamber are maintained at above a specified temperature at which evaporated magnesium does not adhere, and/or a heating member which is to be excited electrically and electrodes used for electrically exciting the heating member, which are the constituents of a heater for heating the aluminum members and the brazing metal, are hermetically sealed and insulated from the inside of the heating chamber.
