An endoscope system includes an endoscope including at least one switch, each of which can be assigned two functions, and a controller. The controller sets a plurality of function pairs, each of which is composed of a combination of any one of a plurality of first functions and any one of a plurality of second functions, and assigns one function pair selected from the plurality of function pairs to the switch, measures a switch pressing time period after the switch is pressed, and executes the first function when the switch pressing is released before a predetermined first time period elapses after the switch is pressed and executes the second function when the switch pressing time period passes the first time period.

An endoscopic device generates an endoscopic image based on an image pickup signal generated by an image pickup device at a distal-end portion of an insertion portion, acquires channel information regarding a channel formed in the insertion portion, acquires angle information regarding a display angle of the endoscopic image, and generates and outputs a display image including a display endoscopic image generated based on modifying the endoscopic image based on the angle information, and a channel guide image generated based on the angle information and the channel information.

This invention provides an oil well pipe which is resistant to fracturing caused by ground subsidence by providing a sliding layer on the outside of the oil well pipe to reduce the frictional force acting on the oil well pipe. Furthermore, by constituting the sliding layer by a material and a thickness so that the residual negative frictional force becomes 2&times;10 N/m or less after 1 year of deformation at the operating temperature of the oil well pipe, or by the sliding layer comprising a material of which the stiffness factor S(t) after 1 year of deformation is in the range from 10 N/m to 10 N/m at the operating temperature of the oil well pipe and providing an adhesive layer between the pipe body and the sliding layer, thereby reducing the sliding phenomenon upon construction which restricts the properties of the sliding layer. Further, by the improvement of the adhesive force of the
