  • Patent number: 5735475
    Abstract: A film feeding device for a camera uses first and second electric motors associated with first and second planetary gearing mechanisms, respectively. In one embodiment, the first motor and first planetary gearing mechanism drive a spool shaft of a film cartridge to supply film to a winding spool. The winding spool is driven by the second motor and second planetary gearing mechanism to wind film onto the winding spool, at which time the first motor is stopped and the first planetary gearing mechanism is automatically disconnected from the spool shaft. For rewinding, the second motor is operated in reverse and the second planetary gearing mechanism is automatically disconnected from the winding spool and connected to the spool shaft of the film cartridge.

  • Patent number: 5734478
    Abstract: A projection exposure apparatus employs light in two different wavelength bands for exposure of a photosensitive substrate and for alignment of the substrate with a mask, respectively. The mask has a window through which alignment light is passed to an alignment mark on the substrate and has a shield for preventing illumination of the alignment mark by exposure light. In one embodiment the position of the shield relative to the window is determined by magnification chromatic aberration of a projection optical system with regard to the alignment light. In another embodiment the path of the alignment light through the window is inclined relative to a line perpendicular to the mask and passes through a pupil of the projection optical system at a point deviated from the center of the pupil.

  • Patent number: 5729255
    Abstract: In an image edit apparatus for editing an image and outputting the edited image, an image can be easily edited without lowering the resolution of a printed image when the edited image is printed. A control portion controls the size of an image in correspondence with the resolution of a color printer when the image is pasted in an edit area. When an image stored in an image library is pasted on the edit area, the control portion performs conversion of the size (Lx, Ly) of the image to be pasted based on the numbers of pixels (Px, Py) of the image, the resolution (Ro) of the color printer, and the resolution (Rd) of an indication device.

  • Patent number: 5726518
    Abstract: A miniaturized ultrasonic motor comprises a stator having an elastic body on which a travelling oscillatory wave is generated and which is supported on a fixing unit in a manner that prevents rotation of the elastic body but permits axial movement of the elastic body. The travelling oscillatory wave rotates a rotor that contacts protruding portions of the elastic body, and the rotor rotates a driven body therewith. The driven body engages the rotor in a manner that constrains the driven body to rotate with the rotor but that permits relative axial movement of the driven body and the rotor body.

  • Patent number: 5720689
    Abstract: For a toroidal type continuously variable transmission, the end portion of a radial needle bearing provided for a trunnion is protruded from the inner face of the trunnion. Also, the inner face of the trunnion is made substantially flat. Therefore, the processing of the trunnion is made easy, and the holder of the thrust needle bearing can be easily positioned simultaneously. Also, the structure is arranged to enable the recess formed on the trunnion to engage with the extrusion formed on the holder, thus preventing any plane pressure from being exerted excessively on the rolling surface of the needles of the thrust needle bearing, as well as preventing the needles from falling out of the pockets of the holder.

  • Patent number: 5719987
    Abstract: An image data recording method in a digital still video camera capable of selecting one of the single shot mode for photographing and recording only a single image and the sequential shot mode for sequentially photographing and recording a plurality of images comprises the steps of distinguishing whether a recorded image was photographed in the single shot mode or in the sequential shot mode, giving a file name correspondingly to the photographed image, and recording the photographed image. File names for each single shot image may be stored at a given hierarchy level. A name (e.g., a subdirectory name) representative of a plurality of sequential shot images may be stored at the same level as the single shot file names and file names of the sequential shot images stored under the representative name at a different hierarchy level.

  • Patent number: 5719698
    Abstract: Recent UV-lithography is required to provide a fine and sharp pattern with a line width of 0.5 .mu.m or less. The present invention provides a silica glass member adapted for use as an optical element for UV-lithography, by giving consideration to the RMS value of wave front aberration and the slant element of refractive index, which have not been considered in the art. Also, there is provided a silica glass member excellent in durability to the ultraviolet irradiation, by introduction of hydrogen molecules at the synthesis of the silica glass, instead of using a secondary treatment for hydrogen introduction.
