Title: Stereoscopic projector
Inventor: OONO YOSHIO
IPC: G02B30/25
Filed: 1983-03-26
Abstract: PURPOSE:To project a stereoscopic image by one projection film by providing a transparent body which changes in angle of polarization by 90 deg. between the film and lenses, and changing the angle of polarization of the transparent body every time the projection film is fed by one frame. CONSTITUTION:The projection film 10 on which right-eye images R and left-eye images L are printed alternately is run to project the images R and L on a polygon rotary prism 18 alternately. Respective prism surfaces 18b of the polygon rotary prism synchronize with frames of the projection film 10, so the images R and L are incident to the transparent body, and the voltage applied to TN liquid crystal is turned on or off every time a short-size slit is detected by a surface detector 21b to project right-eye images R and left-eye images L having a 90 deg. difference in angle of polarization on a screen 5. Therefore, a motion picture is seen stereoscopically through observation spectacles 7 having a right-eye and a left-eye polarizing plate 6a and 6b.

Abstract: PURPOSE:To perfectly prevent double feed of business sheets by allowing the part positioned over the upper edge of the front guide in a rear-surface stop guide for guiding in free elevation an elevator tray on which business sheets are loaded, to be gradually pushed-out in the direction of paper feed. CONSTITUTION:Business sheets 4 are loaded onto an elevator tray 13 which is arranged between a front surface guide 11 and a rearsurface stop guide 12 and can be raised and lowered. An air nozzle 15 for preventing double feed of business sheets 4 and a vaccum belt 16 for paper feed are arranged at the front in the upper part of the business sheets 4. The upper edge 12A over the upper edge 11A of the front-surface guide 11 of the rear-surface stop guide 12 is tilted so as to be gradually pushed-out in the direction of paper feed. Therefore, when the business sheets 4 are raised by the elevator tray 13, the upper part of the business sheets 4 are pushed-out gradually by the inclination of the upper edge 12A of the rear-surface stop guide 12. Thus, the business sheets 4 can be perfectly separated, and only the uppermost business sheet 4 can certainly be sent out.

Abstract: PURPOSE:To simplify the structure of a device by forming a specific slitlike pattern from a light beam of a light source consisting of four LEDs placed in a square, and giving it to one image sensor through a lens to be inspected. CONSTITUTION:A light beam from a light source consisting of four LEDs3 passes through a light feeding lens 4, passes through an M-shaped slitlike pattern 6, made incident on a lens to be inspected 7, and thereafter, reaches an image sensor 1 through an objective lens 9. Also, as for each arrangement, a position of the light source and a reverse side position of the lens to be inspected 7 are installed in an optically conjugate state. In this case, a pattern 5 is held in a roughly conjugate relation against the position of the sensor 10. That is, by moving the pattern 5 in the optical axis direction by a pulse motor 5a, the conjugate relation of the pattern 5 and the sensor 10 is held. A controller 30 derives an optical characteristic of the lens to be inspected 7, based on an output of the sensor 10.

IPC: B29C70/16
Filed: 1985-03-18
Abstract: PURPOSE:To manufacture a product of laminated structure without having crossover or entangling between fibers by a method wherein the rotating direction of a mandrel is converted in every movement of one stroke of a traverse device and whereby a thread is wound by a plurality of strokes with a predetermined winding angle to form the oriented layer of fibers of off-axis. CONSTITUTION:At first, the mandrel 1 is rotated normally, the traverse device 2 moves to the direction, shown by the arrow sign 10R, and, as a result, the thread 81 is wound on the mandrel 1 with the winding angle of +45 deg.. When the traverse device 2 arrives at the end of winding, the thread 81 is fixed to the mandrel 1 in the condition of Dwell. Subsequently, the mandrel 1 is rotated reversely and the thread is wound by the traverse device 2, moving from the neighboring part of the thread 81 into a reversed direction 10L with the winding angle of +45 deg., thus, the thread 82 is wound. The cycle of this shuttling winding is continued until the whole of the surface of the mandrel 1 is covered by the thread and one layer of off-axis fiber oriented layer is formed. Subsequently, the off-axis fiber oriented layer of winding angle -45 deg. is formed.

Abstract: PURPOSE:To supply oil sufficiently to the sliding surface of a rocker arm by installing an oil jet to a cylinder head cover together with providing this rocker arm with a through hole which supplies jetted oil to the sliding surface of the rocker arm. CONSTITUTION:Usually, a hydraulic lifter 30 reiterates expanding/contracting motion in a small scale in order to conduct well-know actions. However, when an engine load is small, a micro-computer operates a solenoid valve 50 by means of engine input signals in order to push a ball check valve 36 so as to connect a pressure chamber 34 to a reservoir 33. At this time, a rocker arm 15, which usually rocks taking the middle point of a shaft 20 as a fulcrum in order to open/close a valve 12, rocks taking the valve top end 12a as a fulcrum in order to suspend valve lift mechanism. As a result, the valve no longer opens or closes. Oil in an oil passage 23 is jetted from an oil jet 24 and directly supplied via a through hole 26 to an inner sliding surface 27, thereby sufficiently lubricating this sliding surface.
