Abstract: An expansion valve includes a valve main body having a valve chamber therein, a valve body arranged within the valve chamber, a valve body support member supporting the valve body, an urging member urging the valve body toward a valve seat, an actuating bar pressing the valve body in an opening direction of the valve against urging force generated by the urging member, and a vibration proof spring suppressing vibration of the valve body or the actuating bar. The actuating bar has an outer peripheral surface of which a part constitutes a contact surface slidably contacting with the vibration proof spring, and the contact surface has a shape by which the amount of deformation of the vibration proof spring becomes greater as the valve body goes towards a closing direction of the valve.

Abstract: The invention provides an expansion valve which can suppress production of an abnormal noise from an expansion valve in a case where an opening degree of the expansion valve is very small. The expansion valve is provided with a valve main body which has a valve chamber, a valve body which is arranged within the valve chamber, a valve body support member which supports the valve body, an urging member which urges the valve body toward a valve seat, an actuating bar which presses the valve body in an opening direction of the valve, a vibration proof spring which suppresses a vibration of the valve body or the actuating bar, and a contact surface with which the vibration proof spring slidingly contacts.

Abstract: A thin film screen of disc form which is semi-transparent is rotated at high speed about its axis at right angles to the projection path of a projected movie or slide picture through an aperture within a main housing for 90.degree. projection through a side aperture by way of an inclined mirror and a close up lens directly into a video camera through its lens system. A second close-up lens is located in front of the transparent screen for focussing the projected picture onto the screen at the focal plane of the close-up lens. A micromotor which is battery operated drives the mylar screen disc at a comparatively higher speed than that of the projected movie picture.

Abstract: Binoculars and a camera with a telephoto lens system are connected by inserting the telephoto lens barrel through a large lumen in the axis of connection of the binocular halves. A bush mounted within the lumen has an aligning groove for receiving an aligning lug on the telephoto lens barrel. A first section of the telephoto lens barrel is connected to the camera and a second section of the telephoto lens barrel connects to the first section. The camera body is positioned above the eyepiece barrels of the binoculars.

Abstract: Binocular telescope containing a camera which enables photographing object scenes with the same multiplication as that of a binocular telescope.
