摘要:
An information processor disclosed herein prevents adverse impacts on higher priority processing due to extremely frequent receive processing when inbound traffic from a network is over-traffic state (under a DoS attack). The information processor attached to a network collects information about traffic state and, if it is determined that over-traffic state is present, deactivates the communication processing function without passing an interrupt request due to communication to the data processing block. In this state, the information processor continues to collect information about traffic state and, when it is determined that over-traffic state has terminated, starts to transfer an interrupt request to the data processing block and makes the communication processing function recover.

In the present invention, a photosensitive layer of an optical recording medium includes a photo-responsive high-molecular compound comprising a photo-responsive group (e.g., an azobenzene derivative) which is geometrically isomerized by light radiation, and a liquid crystal linear mesogen group (e.g., a biphenyl derivative), wherein the photo-responsive group and the linear mesogen group are respectively bonded as side chains. The invention provides an optical recording medium enabling large scale recording by making the photosensitive layer thick without impairing recording characteristics. The photo-responsive high-molecular compound preferably comprises an aromatic ring on a main chain. Further, the photo-responsive high-molecular compound preferably comprises a structural unit which is capable of forming a liquid-crystalline or crystalline polymer and a structural unit which is capable of forming an amorphous polymer.

An optical recording/reproducing apparatus having excellent resistance against vibration and noise. In recording, coherent light is polarization-modulated with a spatial light modulator to generate signal light and reference light whose polarization directions are crossed at right angles. The signal light permeates a polarizing beam splitter, and is incident to a quarter wavelength plate. The reference light passes through a passing hole, is diffused by a light diffuser and is incident to the quarter wavelength plate. The reference and signal light are converted into circularly polarized light which revolve in directions opposite to each other and condensed by a condenser lens, and then a predetermined area of an optical recording medium is irradiated with the reference and signal light. Thus, the reference and signal light are generated by modulating the incident light from the same light source and are coaxially incident to the polarizing beam splitter.

A holographic recording method and a holographic recording apparatus capable of selectively rewriting or erasing only desired data without degrading data other than the desired data are provided. Holograms are multiple recorded per file, and page data in one file is multiple recorded, while page data in one file and page data in another file are not multiple recorded. Therefore, only the desired file can be selectively rewritten or erased without degrading the other files.

The present invention relates to a method for producing an optical recording medium. In the method, on the surface of a recording layer formed by spin-coating a first coating solution containing a photo-isomerizable component, a second coating solution that contains a photo-isomerizable component that can be isomerized by radiation having the same wavelength as radiation used for isomerizing the photo-isomerizable component contained in the recording layer and incapable of dissolving the recording layer is spin-coated to form an intermediate layer. Since the intermediate layer thus formed cannot be dissolved by the first coating solution, a recording layer is further laminated on this layer. Thus, it becomes possible to make the recording layer thicker and also to provide a high-density recording characteristic.

An interrupt control unit provides controls on an interrupt from an accelerator to a CPU based on a packet transmitted to or received from a controlled object. The interrupt control unit includes: a storage part for storing therein an interrupt control timing table in which a condition of switching a mode of the interrupt control is described; and an interrupt control mode switching part for switching the mode of the interrupt control to the CPU between a permission mode and a mask mode, based on the interrupt control timing table in the storage part.
