A method of joining includes applying braze to a braze reservoir in a first component. A second component is engaged to the first component, wherein a joint location is defined between the first and second components. A wicking structure provides flow communication from the braze reservoir to the joint location. The method also includes joining the first and second components together at the joint location by applying heat to the braze to flow the braze from the reservoir through the wicking structure to the joint location to form a braze joint at the joint location.

In the case of a method according to the invention for connecting at least two components of an endoscope, at least one brazing preform, which contains a high-temperature brazing solder, is introduced into at least one brazing solder reservoir of at least one of the components, the at least two components are held in relation to one another in such a way that at least one brazing gap that is in capillary connection with the at least one brazing solder reservoir is formed between joining regions of the at least two components that are assigned to one another, and the arrangement comprising the at least two components and the at least one brazing preform is heated to a brazing temperature of the high-temperature brazing solder. The invention also relates to a component of an endoscope and to an endoscope.

A refrigerant pipe of a refrigeration apparatus includes: a first pipe, made of stainless steel, through which a refrigerant flows; a joint pipe, made of a material different from stainless steel, disposed on an outer peripheral surface of the first pipe; and a second pipe, having a diameter smaller than a diameter of the first pipe, connected to the outer peripheral surface of the first pipe via the joint pipe. A surface of the second pipe at which the second pipe is connected to the joint pipe is made of a material identical to the material of the joint pipe.

To obtain a fuel rail that maintains low hardness and good formability before being formed into a tube stock, can be made to easily form a thin absorbing wall surface, and has a high hardness and pressure resistance so as to be usable not only at a fuel pressure of 400 kPa or less, but also at a relatively high fuel pressure of 400 kPa or more. A fuel rail for port injection that is provided with a fuel pressure absorbing wall surface 1 and is used at a fuel pressure of 200 kPa to 1400 kPa. The fuel rail comprises an iron alloy that includes chemical components of C, Si, Mn, P, S, Nb, and Mo. The fuel rail has an internal volume of at least 60 cc and an amount of change in internal volume, when pressure is applied, of at least 0.5 cc/MPa. A bainitic structure can be precipitated by brazing the fuel rail in a furnace during manufacturing.
