    • PURPOSE:To raise the spike effect on a frozen road and take off a fear of damaging a pavement, by setting movable spikes which are operated by the frictional force, and making the spikes function only on a slippery road. CONSTITUTION:One end of a movable spike 2 is rotatably supported by a bearing 1 with an attaching means, and the other end of it can sway freely in some degree. The space from a tread 3 to the bottom of a groove is filled with a soft elastic body 4, and the spike 2 and the groove guide walls are made adhere to the elastic body 4. At this time, the spike 2 is set as the top of it reaches the almost same height of the tread, and as a line from the center of the swaying to the top of the spike 2, inclines at an preset angle of A against a normal line which is perpendicularly set up on the road surface, when the top of the spike 2 touches the road. Moreover, when the top of the spike 2 is given the frictional force from the road surface, the spike 2 rotates as resisting the reaction force of the soft elastic body 4, and when the frictional force becomes the maximum, the angle A becomes zero or the minimum.

    • PURPOSE:To prevent the obstruction of a light beam sent out from an object and installed a rotary shaft in a black box by setting the optical axis of a photograph lens and the center line of the rotary shaft pivoting a camera body, in mutually twisted positions. CONSTITUTION:The optical axis of an image pick-up lens 1 and a rotary shaft 3 which axially supports a camera body are in mutually twisted positions, and one end of the rotary shaft 3 is fixed on a fixed board by a fixing screw 10. Further, a cylindrical body 4 is fixed in a concentric form on the rotary shaft 3. When the camera body is turned in the clockwise direction around the rotary shaft 3, a film pulled out from a film case 6 is wound on a cylindrical surface, and since the speed becomes equal to the moving speed of an object on the film at a slit, a photographed body image free from blurring is photosensed on the film. Accordingly, a direct transmission type panorama camera can be formed be setting the whole of the cylindrical body 4 into the dark box of the camera and can do without any intemendiate medium.

    • PURPOSE:To enable characters and graphic which show a constellation to be seen in a visual field by rotating a spherical surface, which is supported by a container rotatably in any direction and recorded the constellation, characters and graphic around a diameter as axis parallel to the earth's axis. CONSTITUTION:Two hollow hemispheres which are recorded the characters and graphic, showing the names and figures of the constellation, on their spherical surfaces 7 are joined mutually to form a rotatable hollow sphere. Consequently, the sphere is floated on transparent liquid for flotation and the fitting positions of an internal wall of a float 1, a ring body 5, a coupling piece 10, and the hollow hemispheres 9 are adjusted so that the rotary axis of the spherical surface 7 becomes parallel to the other axis and the cut surface of the hollow hemisphere 9 become horizontal and stationary; and necessary parts are fixed and the rotary axis of the spherical surface 7 is held penetrating the North pole and South pole of the sky. Consequently, the spherical surface 7 is rotated by a rotary driving device 13 at a speed of one turn per sidereal day and then a light image of the constellation can be seen in the visual field through the guide device.
