Abstract: A pair of eyeglasses includes angle adjusting members. In Each angle adjusting member, a supporting shaft member projecting on an inside of the external body and a supporting shaft member projecting on an inside of the internal connect body are connected together and inserted in on a supporting hole provided on the connecting body of the frame. An engaging claw projecting on the inside of the internal connect body is to be selectively engage with one of plural engaging notches provided on the outer edge portion of the connecting body. The external connect body is superposed on an outside of the connecting body and the internal connect body is superposed on an inside of the connecting body. In this pair of eyeglasses, angle adjustment between the lens and the temples is easy. The angle adjusting members does not protrude outwardly from the frame. Replacement of lenses is also easy. Also this pair of eyeglasses has no metal part and does not produce a problem in disposal.

Abstract: An abnormality detection support device, suitable for a case where rescue operations are made under situations that visibility is disturbed by smoke due to fire, includes an infrared camera, a display which, at least when the infrared camera is in use, comes to be positioned in front of a user's eyes and reproduces an image taken by the infrared camera thereon and a face protector or a helmet, on which the infrared camera and the display are provided, and the infrared camera and the display are arranged to be within an outline of the user's head in a front view when the device is put on the user. The present invention can, therefore, provide the abnormality detection support device which enables an operator to work with both hands available while directly watching the infrared image even under a circumstance that smoke or the like due to occurrence of fire disturbs the field of vision of the operator, and has excellent usability.

Abstract: A drive shaft rotated by an electric motor is disposed to penetrate through a main body, and a spindle is concentrically mounted at the distal end of the drive shaft so that the rotational force of the drive shaft moving in an axial direction thereof is transmitted to the spindle. A processing drill head is selectively mounted at the distal end of the spindle that is coupled with a piston which is urged to a first position in an axially forward direction of the spindle by the fluid pressure supplied to a cylinder, for executing a processing work and a retreated position at which a hold mode is set. An abutting member is securely fitted to the outer surface of a piston rod, and a ring-shaped magnetic member is further provided to the outer surface of the piston rod in an axially movable manner, this ring-shaped magnetic member always being urged in the retreating direction.
