摘要:
A content encryption device generates encrypted content and an encrypted content copying device copies the encrypted content on an information storage medium. The storage medium is sold at a charge or distributed at no charge. A user gets the storage medium to connect the storage medium to a user terminal device or set the storage medium in a user terminal device, accesses to a content key distribution device to present a part or a whole of medium information of the storage medium to the distribution device. The distribution device grasps the whole of the medium information of the copied medium together with copied content and makes a content key encryption device issue an encrypted content key on the basis of user presentation information and distributes it to the terminal device.

An equalizing mechanism of a welding apparatus connects an apparatus body and a fixed bracket, and includes a fixed member on the fixed bracket, and a pressure shaft on an apparatus body close to a bottom face of the fixed member. A cutout is at a position facing the fixed member A movable member on the apparatus body accommodates the fixed member. A restrictive member located by side faces of the fixed member and the movable member restricts relative movement thereof to a direction parallel to the pressure shaft. A driven lever is supported by a front portion of the fixed member to abut on an inner front face of the movable member at one end and abut on the pressure shaft at an other end. A spring between a back portion of the fixed member and an inner back face of the movable member presses the two members to move away from each other.

According to one embodiment, an information distribution apparatus stores a characteristic information extracted arbitrary time-series data and relevant information in association of an information providing site on a communication line with each other, fetches characteristic information presented with a request for distribution through the line from a terminal, collates the fetched characteristic information with each characteristic information item of the stored associated information, determines the closest characteristic information, fetches relevant information associated with the characteristic information, and distributes the fetched relevant information to the terminal through the line.

A drive unit of a pressure device, such as a welding gun, includes a piezoelectric type load cell adapted to be arranged in an easily attached and removed manner and to have relatively small capacity. The drive unit includes a through-hole 6, formed in a rotary shaft 5 of a drive motor 1, which is a drive source, and a pressure shaft 10, configured to be able to move with a part thereof being in the through-hole 6. The rotary shaft 5 is rotatably supported by the bearing 7, and the piezoelectric type load cell 17 is sandwiched between a preload striker plate 18, through which the pressure shaft 10 passes, and a preload setting striker plate 19, through which the pressure shaft 10 passes with a preload exerted on the load cell 17.

It is assumed that a reception processing unit receives a broadcast program in accordance with tuning based on the user's specification. In this state, a non-viewable state detection processing unit monitors occurrence of a non-viewable state from an acquisition state of reception data. When the non-viewable state occurs due to a certain factor, a non-viewable state accumulation unit accumulates information on the non-viewable state. When the factor of a viewing interruption is solved and a user makes a request for service provision, the processing unit connects to a distribution apparatus to report content of the non-viewable state, and receives distribution of a relevant content, thereby the processing unit becomes able to recontinue interrupted broadcast content.

In a transport stream distribution system, a transmission rate control unit takes in an IP packet output from an IP transmission processing unit, obtains a TTS to be added to an arbitrary TS packet in the IP packet, and compares the TTS with a time stamp generated internally to determine whether both of them coincide with each other or not. And if they coincide with each other, the system takes in a TTS of the next TS packet, and otherwise, the system obtains a difference between a time indicating the TTS and the time indicating the internally generated time stamp to calculate a transmission rate correction value equivalent to the value of the difference, and issues the calculated correction value to the processing unit to correct a transmission rate.
摘要:
A content delivery apparatus, when a content delivery request is outputted from a user terminal device, encrypts the requested content with an encryption key, adds a view period to it to deliver it to a request source and delivers a viewing key in response to a view request from the user terminal device within the view period. A user relief management unit monitors failure information notifying, grasps a delivery disabled period from the failure information, specifies a delivery destination user for a content of which the view period is overlapped with the delivery disabled period and issues a relief right with a relief period specified thereto to the specified user. A contract period processing unit manages the relief right and permits viewing within the relief period set by the relief right when a view right based on the relief right is output from the user terminal device.

摘要:
A content encryption device generates encrypted content and an encrypted content copying device copies the encrypted content on an information storage medium. The storage medium is sold at a charge or distributed at no charge. A user gets the storage medium to connect or set it to or in a user terminal device, accesses to a user management device to receive permission by authentication information distributed together with the storage medium and presents a part or a whole of medium information to a content key distribution device. The distribution device makes a content key encryption device issue an encrypted content key on the basis of the presented information and distributes it to the terminal device.
