  • Patent number: 7888596
    Abstract: In an upper surface of a bottom wall of a box body having a part accommodation room formed inside, a recess is provided. In the bottom of the recess, a bolt hole to fix an electrical junction box to a vehicle body is penetrated. In the upper surface of the bottom wall of the body hole, a flat sealing surface is formed to surround an opening of the recess. When an electronic unit is accommodated in the part accommodation room, the bottom surface of the electronic unit is brought into close contact with the sealing surface to close the recess, thus providing a seal between the part accommodation room and recess.

  • Publication number: 20100246371
    Abstract: According to a first aspect of the invention, an optical information recording apparatus includes a spatial beam modulator, an optical component, a drive unit, and a control unit. The apparatus performs angle-multiplex recording of the information so that an absolute value of a bisector angle ?x for n-th recording (1?n?rN) is smaller than an absolute value of a bisector angle ?x for m-th recording (m>n and rN<m?N). Here, N is the number of pages to be defined as the total number of recording times performed on a recording spot of an optical information recording medium. The n-th recording is performed on the recording spot with the reference beam and the information beam. r is a rate to be determined by a volumetric shrinkage of the optical information recording medium. The volumetric shrinkage increases with irradiating the optical information recording medium with the reference beam and the information beam.

  • Publication number: 20090080314
    Abstract: An optical recording/reproducing apparatus includes an optical recording medium in which a holograms are recorded depending on an incident angle of a reference beam. The reference beam is irradiated to holograms while changing the incident angle to generate a reproduction light beam, and an image patterns are detected by an image pattern detector. The continuously output reproduction image patterns are temporarily stored in an image recorder, and the maximum value of reproduction light intensity is detected to generate a trigger signal. Depending on the trigger signal, an optimal image pattern is extracted from continuous reproduction image patterns, and thus, two-dimensional data is decoded.
