Disclosed is an optical disk barcode forming method wherein, as information to be barcoded, position information for piracy prevention, which is a form of ID, is coded as a barcode and is recorded by laser trimming on a reflective film in a PCA area of an optical disk. When playing back the thus manufactured optical disk on a reproduction apparatus, the barcode data can be played back using the same optical pickup.

A scanning microscope includes: a light source; an optical system that irradiates light from the light source onto a sample while two-dimensionally scanning the light, and collects light from the sample; a photo-detector that receives the light from the sample which has been collected by the optical system, and converts the light thus received into a brightness signal; an integrating circuit that integrates the brightness signal from the photo-detector for each pixel; and an image forming circuit that forms an image of the sample based upon the brightness signal of each pixel integrated by the integrating circuit. And the integrating circuit includes a plurality of integrators for integrating the brightness signal from the photo-detector and an adder for adding output signals from the plurality of integrators, and integrates the brightness signal while sequentially switching the plurality of integrators for each of a plurality of periods obtained by dividing a period corresponding to a pixel.
摘要:
A subject for the invention is to obtain trans-1,4-cyclohexanedicarboxylic acid (t-CHDA) in a high concentration by efficiently isomerizing cis-1,4-cyclohexanedicarboxylic acid (c-CHDA) by a simple method. The invention provides: (1) a process for producing t-CHDA which comprises heating crude CHDA to 180° C. or higher in an inert atmosphere and causing the t-CHDA formed by isomerization to precipitate in the molten c-CHDA while holding the crude CHDA at a temperature in the range of not lower than 180° C. and less than the melting point of t-CHDA; (2) a process for producing t-CHDA, wherein crude CHDA which is powdery or granular is heat-treated at a temperature of not lower than the melting point of c-CHDA and lower than the melting point of t-CHDA to thereby isomerize the cis isomer to the trans isomer while maintaining the powdery or granular state; (3) a process for producing t-CHDA, wherein crude CHDA is held at a temperature of not lower than the melting point of c-CHDA and lower than the melting point of t-CHDA in an inert atmosphere while maintaining flowing to thereby obtain powdery or granular t-CHDA; and (4) a process for purifying crude CHDA in which crude CHDA obtained through the step of hydrogenating TPA or the like is heated in an atmosphere of an inert gas to volatilize and remove impurities.

A high-level synthesis method is provided for synthesizing a register transfer level logic circuit based on a behavioral description in which processing behaviors are described. The method includes the steps of extracting information on a bus connection resource from the behavioral description, storing the information on the bus connection resource in a bus connection resource database, referencing the bus connection resource database, referencing a bus protocol library having a preloaded bus protocol, and automatically generating a target interface circuit based on a result of each of the bus connection resource database referencing step and the bus protocol library referencing step.

A device for recording information on an optical disk having first and second recording areas, which device can record information into the first recording area, using a first modulation method; read disk identification information recorded by a second modulation method in the second recording area; detect auxiliary information indicating the presence of disk identification information; encrypt information using both a cipher key and the disk identification information unique to the optical disk; and permit recording of encrypted information after confirming the presence of the disk identification information.
摘要:
The operating and other procedures of a disk or recording medium application system of the type for which a network is used are simplified. Disks or recording media have auxiliary data recording areas, where different IDs for individual disks, and/or cipher keys and/or decoding keys for ciphers are recorded in advance in a factory. By using the IDs to release the soft ciphers, using the cipher keys when sending the ciphers, and using the decoding keys when receiving the ciphers, user authorization procedures are simplified.
摘要:
A barcode is formed on an optical disk. The optical disk is provided with a control data area and an identifier for indicating the presence or absence of the barcode in the control data area. A beam pattern if focused on a reflective film of the optical disk in an information signal region on which the data is recorded. Information is provided for making the barcode. The information is PE-modulated so that a width of a mark of the barcode is half or less than a period of the barcode marks. The optical disk is rotated to form the barcode.
摘要:
In an element intrinsic region 12 of a bipolar transistor, an emitter is formed by two emitter layers 31,32 so as to reduce the potential barrier presented to minority carriers, this resulting in a smooth flow of minority carriers that are injected into the base layer from the emitter, and in the element external region 13, the emitter layer 32 that acts to reduce the potential barrier to injected minority carriers is removed, thereby suppressing the injection of minority carriers from the emitter layer 31 into the base layer.
摘要:
A device for reading encrypted information recorded on an optical disk having first and second recording areas, the device can read disk identification information recorded in the second recording area, select a specific decipher key among multiple decipher keys, and decrypt encrypted information from the optical disk using both the disk identification information unique to that optical disk and the specific decipher key.
