摘要:
This method for producing silicon single crystals includes: growing a silicon single crystal by the Czochralski method while cooling at least part of the silicon single crystal under growth with a cooling member which circumferentially surrounds the silicon single crystal and has an inner contour that is coaxial with a pull axis, wherein an ambient gas in which the silicon single crystal is grown includes a hydrogen-atom-containing substance in gaseous form. This silicon single crystal is produced by the above method.

IC card (300) supplies an encryption key which enables content use, to a terminal apparatus (200) belonging to a domain made up of terminal apparatuses (200) which share the IC card (300). The IC card (300) includes: an extra-domain usage rule holding unit (305) which stores a rule for use of the IC card (300) in a terminal apparatus (200) which is outside of the domain; and an extra-domain use permission judgment unit (309) which judges, according to the usage rule, whether or not use of the IC card (300) is permitted, when the IC card (300) is provided to the terminal apparatus (200). The IC card (300), in addition, supplies the encryption key to the terminal apparatus (200) which is outside of the domain, when the extra-domain use permission judgment unit (309) judges that use is permitted.

In an on-Internet multicasting content delivery system, information on each sub license in ECM (Entitlement Control Message) body includes a license ID as sub license identification information, type information indicative of whether a sub license is for preview or actual viewing and a location indicative of a stored position of the sub license in a license part (number of bytes counted from the top of the ECM body). The license part stores sub licenses.

A broadcast station that is a transmission device assigns an ID and a license transformation period to a license to be generated, and transmits to a terminal apparatus 102, in order to provide a digital right management system which can provide a protection for the rights of a provider while preventing an unauthorized obtainment of a license to be transmitted through a digital broadcast. The terminal apparatus 102 records a license import log including the license ID and license transformation period assigned to the license. Further, the terminal apparatus 102 controls a license obtainment in the case where the same license has been obtained by the time of obtaining the license. Furthermore, the license received by the terminal apparatus 102 is kept at least until the license transformation period expires.

An ink jet recording head having improved printing performance and improved manufacturing efficiency, a manufacturing method of the ink jet recording head, and an ink jet recording device. A head chip in which nozzles for jetting ink droplets are formed is fitted in an opening of an ink manifold via rubber sealing members, and the chip is exposed to the interior of ink supply chambers. Thus, the chip is efficiently cooled by the ink, and the temperature of the ink can be controlled so as to be within a predetermined range. Accordingly, no heat sink is necessary, and as a result, the head is easily manufactured and made compact. Since the chip is fitted in the manifold opening via the sealing members, application of an adhesive and curing time are unnecessary. Thus, manufacturing efficiency is improved.

摘要:
A scrambled transmission system for transmitting a digital data containing variable length coding conforming to a MPEG standard includes a scramble key generator for generating a scramble key at a timing of each GOP head. A GOP head detector detects each GOP head and causes the scramble key generator to refresh the scramble key. A seed generator generates a scramble seed based on said scramble key at a timing of each slice head. A slice head detector detects each slice head and causes the seed generator to refresh the scramble seed. A random number generator scrambles the digital data based on the scramble seed. A multiplexer embeds the scramble key in the extension.sub.-- and.sub.-- user.sub.-- data of the scrambled data.
摘要:
A transparent electrode, luminescent layer, back electrode are formed on one side of a first insulative substrate. A second insulative substrate is adhered to the first insulative substrate by an insulative adhesive. The back electrode is divided into two sub-electrodes. A pair of electrode pads are formed on the second insulative substrate so as to be opposed to at least respective parts of the sub-electrodes, and connected to those parts of the sub-electrodes by a conductive connector.
