摘要:
An endoscope has a bendable portion configured to be operated to be bent within one plane which is parallel to an axial direction of an endoscope insertion part 13 on a distal end side of the endoscope insertion part 13. An outer peripheral surface of the bendable portion is covered with an elastic tube 31 having flexibility. A rigidity of the elastic tube 31 in directions L and R orthogonal to bending operation directions U and D is higher than that of the elastic tube in the bending operation directions U and D.

A printed wiring board for mounting a semiconductor, which printed wiring board has a taper-shaped through hole connecting an upper surface circuit and a lower surface circuit, and/or an internal layer circuit, the taper-shaped through hole being obtained by plating an inner wall surface and a small-diameter side end of a taper-shaped penetration hole with a metal to plate the inner wall surface and seal the small-diameter side end, wherein a ball pad or a bump pad is formed at at least a small-diameter side end of the taper-shaped through hole.

An endoscope system has an insertion portion and a control portion connected to a base end portion of the insertion portion. An illumination system includes a light guide having a front end positioned near the front end of the insertion portion and a rear end positioned rearward of the base end of the insertion portion, phosphors disposed in the light guide toward the front end thereof and an illumination light source which is positioned toward the rear end of the light guide and emits stimulating light exciting the phosphors.

The insertion part of the endoscope has a cap fixed to the distal end face of a distal end body. A projecting part of the cap is inserted in a receiving hole formed on the distal end face. The inserted projecting part is fixed to the distal end body with a screw inserted in an attachment hole, which is formed on the periphery of the distal end body and connects with the receiving hole. Bending rubber covers the attachment hole as well as the outer periphery of the distal end body.

In an endoscope tip part in which a lens barrel is arranged and fixed to a mounting hole of a support body of the endoscope tip part and to this lens barrel, and an optical member such as an optical filter or a prism is connected by an optical part holding fixture, a part of an endoscope outer peripheral side of the optical part holding fixture is cut off, and to this notch part, the mounting hole is extended out like an extending part, and a step part on an outside of this support member is made deep (diameter is reduced). If an end part of an outer skin is bound with a string on this step part with a small diameter and fixed by adhesives, a swell of an outer skin fixing part is eliminated, and an insertion of the endoscope also becomes easy.

A catalytic combustion heating device 3 for generating heat by oxidation reaction of fuel gas stored in a fuel tank 24 and air in a combustion unit 29 is installed in a mount 4 provided in a jacket 1. The mount 4 is fastened to the waist of the body wearing the jacket 1 by a holding band 9, and the load applied on the shoulders through the jacket is lessened and comfort is improved. Thus, a warming jacket capable of warming the body comfortably is obtained.

An output voltage of a commercial power source 1 is rectified through a diode 2, and partially dropped at a voltage drop element 19. Electric power supply to a heater 8 is controlled by a heater controller 7, which is activated in response to an output of a heater control actuator 4. A timer 5 counts time. When a predetermined period of time has passed, heater control actuator 4 causes heater controller 7 to open the power supply circuit of heater 8 so as to forcibly stop the power supply to heater 8. An output terminal of voltage drop element 19 is connected in series with at least two of heater control actuator 4, timer 5 and sensor 20.
摘要:
A groove is formed on both side faces of a fixing member to which a wire for bending an angle portion is fixed, a T-shaped attaching hole having a locking portion (T-shaped perpendicular portion) by which the groove for fixing is locked is provided on a side face of an angle ring, and the groove for fixing is fitted in the locking portion of the attaching hole so that the fixing member is detachably attached. On the fixing member, a screw hole may be formed so that the fixing member is screwed to a distal-end portion main body by inserting a screw through the screw hole and the attaching hole. Alternatively, on an edge of the locking portion, a perpendicular projection portion projecting in a perpendicular direction may be provided so as to enhance strength of the locking portion.
