摘要:
An electron beam irradiation system is offered which is fitted with a rotary stage and capable of preventing vacuum deterioration when a target is mounted and removed without using a large stage as the rotary stage. The system has a pumping block at an end of a microscope column of electron optics. A method used for this purpose is also offered. The system has the rotary stage, the microscope column for shooting an electron beam at the target on the rotary stage, the pumping block for evacuating air in the gap between the column and the target, a moving mechanism for sliding the rotary stage between a working position and a mounting position, and a cover member. In the working position, the target is opposite to the column. In the mounting position, the target is spaced from the column. The cover member is brought into intimate contact with the rotary stage or target to prevent vacuum deterioration when the rotary stage moves from the working position to the mounting position.

There is provided an optical modeling apparatus (1) that forms a model of a desired shape by sequentially forming hardened layers by irradiating a light-curable resin with light. The apparatus includes a first light source (11) that emits a light beam for plotting on the resin, a scanning device (21,22) that scans the light beam from the first light source over the resin, a second light source (31) that emits light that irradiates one fixed region of the resin at a time, and a spatial light modulator (32) that spatially modulates the light from the second light source (33) to blanket-expose a specified region of the resin. The light beam from the scanning device (21,22) and the light from the spatial light modulator (32) form each hardened layer.
摘要:
An information transmitting method comprising the steps of: transmitting identification information of a recording medium from at least one terminal section for reproducing a duplicate recording medium duplicated from the recording medium having recorded thereon first digital data related to an encrypted work and second digital data including at least identification information proper to the medium, to a host section via a communication channel; authenticating the transmitted identification information by the host section; requesting the terminal section for accounting; and transmitting data related to a key for decrypting the encryption of the first digital data to the terminal section when the accounting is carried out.
摘要:
A data outputting method for reproducing and outputting digital data including at least work data recorded on a data recording medium and identification information for carrying out identification proper to the data recording medium recorded on the data recording medium, the method comprising the step of data-converting the reproduced digital data using the identification information, and outputting the resultant data.
摘要:
An optical recording medium is capable of linear recording in a photon mode. An organic material changed in molecular orientation on light illumination to exhibit birefringence is used as a recording material. For example, a recording layer having, as a recording material, an organic material changed in molecular orientation caused by trans-cis rearrangement, is changed in birefringence with changes in the molecular orientation of the organic material. The recording system which utilizes the changes in the molecular orientation of the organic material has linear characteristics and gives outputs different depending on e.g., the degree or the angle of orientation, thus enabling multi-valued recording.
摘要:
A direct viewing picture image display apparatus wherein a good picture image can be displayed with a small amount of light and low power consumption using a laser beam without producing speckle noises. The display apparatus comprises a light source (1) for emitting a laser beam, an optical modulating system (3) for optically modulating the laser beam from the light source in response to a video signal (2), a scanning system (5) for horizontally and vertically scanning the modulated laser beam from the scanning signal in response to a scanning signal, and a projecting optical system (6) for projecting the scanned laser beam from the scanning system to form an image of the laser beam on the retina of an eye (7) of an observer of the display apparatus. Depth information is provided to the laser beam at a suitable stage after optical modulation by the optical modulating system so that a stereoscopic image is displayed with the display apparatus.
