Abstract: An optical disk apparatus has a rotation section which rotates an optical disk having a photoimageable layer, a pickup section having a laser radiation section which irradiates the laser light onto the photoimageable layer, a driving section for the pickup section, an irradiation driving section which supplies a driving current to the laser radiation section, a generating section which receives image information, adds identification information for the image information thereto, and generates drive information for the pickup section and the irradiation driving section, based on the image information, and a control section which, in accordance with the drive information, controls the position of the laser light by controlling the driving section, and controls gradation of a visualized image, to render a visualized image on the optical disk in accordance with the image information and the identification information.

Abstract: An integrated network installation system which comprises an execution section having function specification means for specifying a network function of an information processor connected to a network, and preparation means for preparing installation data corresponding to the network function of the information processor specified by the specification means and a display section for connecting the information processor to the network based on the installation data from the execution section, and displaying it.

Abstract: Parameters representing types of machines to be connected to a network, connection types thereof to the network, and operation modes thereof in the network system are set from an information processing apparatus. The obtained parameters are written as parameter files on a recording medium. In each network machine, a network system is automatically constructed by referencing the files. Consequently, the parameter setting operations for the installation of the machine are simplified and there is achieved automation of operations in each network machine.

Abstract: A scraping blade for use in a thin film dryer adapted for processing radioactive substances comprises a main body, a hing member rigidly attached to one side of the body and pivotably connected to a rotor in the dryer, a blade chip attached to the other side of the body for engaging the radioactive substance, and a screw member engaged with the body to secure the blade chip to the body. The blade chip is made of a material more than 1.2 times harder than the radioactive substance. The blade may further comprise an engaging member for screw engagement with the screw having edge portions to be engaged with recesses formed on the blade chip and the main body.
