  • Patent number: 8199351
    Abstract: A client apparatus is coupled to a server apparatus via a network in an information processing system. In the server apparatus, installing of a plug-in file in a first storage apparatus is detected, binary image data of the detected plug-in file are written to a first storage area, and the binary image data of the plug-in file is copied to the client apparatus. In the client apparatus, copying of the binary image data of the plug-in file in a second storage area is detected, the binary image data of the plug-in file stored in the second storage area is written in an executable state within a second storage apparatus, and the plug-in file in the second storage apparatus is read as a program.

  • Patent number: 5694385
    Abstract: Small-sized and light-weighted optical pickup apparatus capable of eliminating the effect due to the flaring light rays and performing the signal detection of high reliability is provided. In the apparatus, the quarter-wave (.lambda./4) plate and the reflection-type birefringent prism provided with the deflecting function of deflecting the reflection light rays reflected on the optical information recording medium and the light rays flux separating function of separating the reflected light rays from the outgoing light rays are disposed in the optical path between the semiconductor laser constructing the optical pickup portion and the objective lens, and the light-receiving element for receiving the reflection light rays from the optical information recording medium which are defleced and separated by the reflection-type birefringent prism is disposed on a single (same) substrate together with the semiconductor laser.

  • Patent number: 5077235
    Abstract: A method of manufacturing a semiconductor integrated circuit device having a SOI structure includes the following steps. The first step is to form a semiconductor layer on a dielectric substrate. The second step is to form an oxide layer on the formed semiconductor layer. The third step is to form a nitride layer on the formed oxide layer. The fourth step is to remove a part of a plurality of layers composed of the semiconductor layer, the oxide layer, and a nitride layer so as to form a separated region in the layers. The fifth step is to coat a cooling agent on a surface of the nitride layer. The sixth step is to irradiate an energy beam from an outer surface of the cooling agent so as to monocrystallize the semiconductor layer. The seventh step is to remove the cooling agent from the surface of the nitride layer. And the final step is to oxidize a portion of the semiconductor layer located in the separated region by using the nitride layer.
