An apparatus for holding an insertable part of an endoscope positioned in a combustion chamber of a reciprocating engine or rotary engine having ignition plug holes to observe the interior of the combustion chamber and an inspecting method are provided with a holding apparatus for stationarily holding the insertable part in the combustion chamber through a spark plug hole provided in the engine to insert a spark plug for a spark plug ignition into the combustion chamber.

Endoscope holding apparatus for inspecting the interiors of a

The endoscope system of this invention is formed of an endoscope having an insertable part provided in the tip part with an illuminating window and a receiving window receiving an object image illuminated by an illuminating light emitted from the illuminating window and a plurality of sheaths selectively and removably connected to the endoscope, inserted through the insertable part when connected to the endoscope and having respectively different functions.

Endoscope system

Disclosed is an industrial endoscope system having a rotary treatment member, attached to a hard top part at a distal end of an insertion unit, for effecting a treatment such as grinding by rotating this treatment member itself. The system includes a moving means for making a distal end of the treatment member movable in the axial directions of the insertion unit. This easily leads the treatment member to a target position via a lead-in port of an engine; or the treatment member can be set in a position suitable for the treatment.

Industrial endoscope system having a rotary treatment member

An eddy current flaw detecting endoscope apparatus has an endoscope having an elongate insertable part and an objective optical system provided on the tip side of the insertable part. A flaw detecting device is provided on the tip side of the endoscope. A signal processing device processes a signal for the flaw detecting device. An eddy current flaw detecting apparatus detects a flaw in an object to be inspected and generates a flaw detecting signal. A controlling device generates a control signal controlling a controlled device with a flaw detecting signal of the eddy current flaw detecting apparatus.

Eddy current flaw detecting endoscope apparatus which produces signals

A borescope apparatus comprising a flexible insertion section, a jet port formed at the insertion section, a moving device for supplying a compressed fluid to the jet port, whereby the insertion section is moved by an impellent force of the fluid ejected from the jet port, and a stabilizing device for steadily maintaining the position of the insertion section.

Borescope apparatus

A tip attachment provided with a mount fittable to a mount receptacle in the tip part of an endoscope is made to appear within the visual field of an observing optical system provided in the tip part before the tip attachment comes to separate from a predetermined fitted state so that the tip attachment may be prevented in advance from dropping.

Endoscope apparatus provided with a tip attachment loosening confirming

An endoscope includes a cap screw body rotatably mounted on a distal end member thereof and having a male threading means for mounting a cap, the cap detachably fitted on the distal end member and having a female threading means for threadably engaging with the cap screw body and a pin projectingly provided therein, and a fitting groove including an axial groove and a peripheral groove provided on the outer peripheral surface of the distal end member for fitting the pin, such that the cap is securely mounted by smoothly moving the pin along the fitting groove without binding between the male and female threading means while the pin moves within the peripheral groove.

Means to facilitate detachably mounting cap to distal end of endoscope

In the insertion part of at least one of an endoscope and an endoscope auxiliary inserted through this endoscope, guide wire receivers for curving wires passed through curvably jointed knot rings formed on the tip side of the insertion part are engaged and fixed respectively within incisions formed in the knot rings.

Curvable part device for endoscope devices

An optical adaptor incorporating a projecting optical system, view field-changing optical system and at least one index attached to said projecting optical system is provided to be attached detachably to the tip portion of insert member of an endoscope equipped with an illuminating optical system for illuminating an object and an objective optical system for focusing the object into the elongated tip of the insert member, thereby enabling measuring the length of the object by projecting the index to the plane including the object.

Adaptor for measuring length optically for endoscope

An endoscope includes an indicating index disposed between an objective optical system and an image transmitter so as to be movable in cooperation with the objective optical system through a cam mechanism and a stationary reference index disposed in a path for transmitting an image of an object to be observed, so that measurements of an actual size of the object, a magnification of the objective optical system, an object distance and the like can be made in a reliable manner based on the positional relationship between the indicating index and the stationary reference index, although the objective optical system moves due to a focus adjustment operation. In addition, an endoscope is provided with a plurality of the stationary reference indexes so that the above mentioned measurements can be made in a reliable manner, although the objective optical system moves by operation of an angle of view converting apparatus.
