Technical Examples
- In a disk stand device and a disk storage device for use in compact disks, mini disks and floppy disks, an array of grooves (2) are provided on an upper surface of a pedestal (1) at predetermined intervals (L). When one end of a disk (3) is inserted into the groove (2) upon accommodating the disks (3), a plurality of disks (3) are positioned to overlap with the predetermined intervals (L) therebetween. A title labelled on the disk (3) can be visually recognized through the intervals (L) of the neighboring disks (3). Upon reusing the disk (3), the disk (3) can be taken out of the groove (2) quicky to improve an efficiency at offices in which electronic computers are employed.
- A holographic printer is disclosed which produces an intermediate hologram H3 and uses the intermediate hologram H3 to produce a white light viewable hologram H2.
- A simplified method is provided for recording identification information, such as a serial number or the like, in a hologram-recorded film simultaneously with hologram duplication. The method includes the steps of coupling a hologram recording film with a master hologram plate having a master hologram, the master hologram plate having a reflective area adjacent the master hologram; and directing laser beams towards the master hologram plate to induce interference between incident laser light and diffraction laser light from the master hologram in the recording film, at least some of the laser beams radiating the reflective area through a transmission type controllable display device to record a pattern in the hologram recording film corresponding to a pattern displayed at the transmission type controllable display device.
- A hologram imaging device for obtaining hologram images and associated document markings which are commonly being used for document verification is disclosed. The imaging device comprises a housing defining an imaging chamber, camera, hologram light source, document light source and imaging platform. The hologram light source consists of a series of illumination devices (e.g., LEDs) adjustably mounted in an arc or semicircular arrangement. An LED controller regulates the state of the LEDs by controlling whether each LED is on or off and adjusting the intensity of each LED in an on position. During use, a document is secured within the housing by the imaging platform such that a hologram or other document marking is positioned beneath a camera lens. Then, the LEDs of the hologram light source are regulated by the LED controller such that different images and/or colors of the hologram may be captured by the camera. Consequently, a series of images and/or colors of the hologram are captured without the requirement of moving the hologram, camera or LED array during the process.
- Various apparatus and methods are provided for handling and transporting pairs of gap merge disks. A transfer member is provided in one embodiment which engages the outer perimeter of a pair of disks at three locations. The transfer member is configured to induce an angled tilt to the respective disks such that the bottom perimeter edges of the disks are spaced apart and the top perimeter edges of the disks are in contact. A mandrel is also provided which is configured to engage a pair of disks oriented in this fashion at the center aperture for purposes of transferring the pair of disks from the transport device to a second location for processing or transfer to another processing device.
