    Abstract: An ultraviolet radiation projector of this invention includes a focusing optical member arranged between an exposure surface of an ultraviolet sensitive material and a panel surface of a CRT for emitting an ultraviolet beam to expose the exposure surface which is kept separated from the focusing system, thereby preventing contact between the exposure surface and any element of the focusing system. An optical image forming apparatus of this invention can form a high-precision two-dimensional image for an electronic circuit pattern by exposing the exposure surface with a pattern corresponding to a desired electronic circuit pattern using the ultraviolet radiation projector as a light source. In addition, sheet-like resins cured by the exposure with the ultraviolet beam using the ultraviolet radiation projector as a light source are sequentially stacked to form a desired high-precision three-dimensional image.

    Abstract: The optical recording medium has main data recorded on a recording track that has been formed in advance along the track direction, and the recorded data are read out by optical system. Frame synchronising signals based on the same format as the main data format are recorded in advance for each frame that serves as a data recording unit utilising the displacement in the direction of width of the recording track itself, whereby the frame synchronism is easily obtained and the constitution is simplified as a result of using the synchronising circuit in common. The data to be recorded in advance by displacing the track itself in the direction of width include frame synchronising signal as well as any reproduction-only data, in order to increase the recording capacity of the disk. The circuit constitution is simplified by using in common the reproducing circuit for reproducing frame synchronising signals of main data recorded in the track direction of the recording track and the reproducing circuit for reproducing frame synchronising signals of the same format as the main data in the data recorded being displaced in the direction of track width.

    Abstract: A three-dimensional object is produced by repeatedly exposing successive layers of liquid photosetting resin (3) at the surface of a quantity of the resin (3) stored in a vessel (2) to a light beam (21) so as to change each light beam exposed layer of the liquid photosetting resin (3) into a solidified layer, stepwise incrementally moving each solidified layer downward into the liquid photosetting resin (3) in the vessel (2) so that a new layer of the liquid photosetting resin (3) is coated on the solidified layer, detecting the temperature of the liquid photosetting resin (3), and heating the liquid photosetting resin (3) in accordance with the detected temperature to maintain the fluidity of the liquid photosetting resin (3).

    Abstract: The present invention is concerned with control and detection of a laser beam for an optical disc recording/reproducing apparatus in which the intensity of a return laser beam reflected by an optical recording medium of a recording laser beam used for forming pits (P) and recording data on the recording medium during the recording mode is detected and an error signal including focusing and tracking error signals of the recording laser beam is formed on the basis of a detection output of the intensity of the return laser beam within a predetermined time interval ( tau ) before the pit (P) starts to be formed by the recording laser beam on the recording medium to control the recording laser beam, and in which, when recording data on the optical recording medium having sub-data previously recorded thereon as pre-grooves with wobbling, these sub-data are detected on the basis of the detection output of the return laser beam within said predetermined time interval ( tau ) or within a predetermined time interval other than said predetermined time interval ( tau ).
