Abstract

A method produces an inner spiral grooved tube using a first drawing die, a second drawing die, and a revolving flyer. The method includes two twisting-drawing steps. The first twisting-drawing step forms an intermediate twisted tube by reducing the diameter of a linear grooved tube, which has plural straight grooves formed along the longitudinal direction on its inner surface, by passing the linear grooved tube through the first drawing die and then by revolving the liner grooved tube wrapped around the revolving flyer with the revolving flyer, in conjunction with imparting twist to the linear grooved tube. The second twisting-drawing step forms the inner spiral grooved tube by reducing the diameter of the intermediate twisted tube by passing the intermediate twisted tube, which revolves with the revolving flyer, through the second drawing die in conjunction with imparting twist to the intermediate twisted tube.

Abstract

In order to enable a satisfactory fluxless brazing without needing flux or vacuum facilities, a brazing object including an aluminum alloy material provided with an Al—Si—Mg brazing filler metal is joined by the Al—Si—Mg brazing filler metal without the use of flux by heating the aluminum alloy material, when raising the temperature in a brazing furnace, at least in a temperature range of 450° C. to before melting of the filler metal under a first inert gas atmosphere having an oxygen concentration of preferably 50 ppm and following by heating at least at or above a temperature at which the filler metal starts to melt under a second inert gas atmosphere having an oxygen concentration of preferably 25 ppm and a nitrogen gas concentration of preferably 10% by volume or less. The oxygen concentration and nitrogen concentration in the atmosphere in the course of brazing are controlled in this way, whereby the reliability of a joint is remarkably improved, compared with conventional fluxless brazing methods, while suppressing cost increases as much as possible.

Abstract

A method of controlling a hydraulic system, the hydraulic system including a ram cylinder unit having a cylinder and a ram, and a hydraulic pump and a reservoir used to supply hydraulic fluid to the cylinder, and hydraulically driving the ram using the hydraulic fluid so as to move against a specific load, the method includes determining what a present state is one of an initial state, a proportional steady state, and a later state, controlling the pumping rate, which is obtained by adding the flow rate corresponding to the volume loss due to the compression of the hydraulic fluid thereto, to control the ram in the initial state, and controlling the pumping rate, which is obtained by subtracting the flow rate corresponding to volume recovery of the hydraulic fluid due to the relief of compression of the hydraulic fluid therefrom, to control the ram in the later state.
