To provide a provisioning system capable of providing a valid device with valid provisioning data and preventing intrusion of an unauthorized device. A device provisioning system that provides a devicewith provisioning data for provisioning the deviceincludes: public key providing means configured to acquire a first public key unique to the devicefrom a blockchainstoring the first public key in association with a first trail in response to a query using the first trail; and provisioning data providing means configured to acquire the first public key through the public key providing means in response to a query using the first trail from the deviceand transmit the provisioning data encrypted with the first public key to the device

Device provisioning system

An electronic certification system that can simplify a process for verification of reliability while improving reliability. The electronic certification system guarantees reliability of data using an audit trail registered in a blockchain, the data being provided to a second terminal such as a client by a first terminal such as a server, the first terminal includes audit trail registration for registering information and the data as the audit trail in the blockchain, the information relating at least one of the first terminal, an administrator of the first terminal, and a program configured to run on the first terminal and exchange the data with the second terminal, and an audit trail provider for transmitting the audit trail to the second terminal. The second terminal determines that the data is reliable if the audit trail provided by the audit trail provider has been registered in the blockchain.

Electronic certification system

A motor capable of holding a vibrator without increasing a dimension thereof in a traveling direction (driving direction) and without having looseness. The motor includes a vibrator and a holding unit that holds the vibrator, and moves the vibrator and a sliding member in frictional contact with the vibrator relative to each other by vibrating the vibrator. A pressurizing unit pressurizes the vibrator against the friction member, and holding springs generate a holding force for causing the holding unit to hold the vibrator. The holding unit is not disposed between the pressurizing unit and the vibrator. A holding direction of the holding force generated by the holding springs and a pressurizing direction of a pressurizing force generated by the pressurizing unit are substantially parallel to each other.

Motor using vibrator, and electronic apparatus

A game system includes multiple game machines which implement a game by alternating turns. Each game machine implements the game on its turn, and transmits game progress information to the other game machines. The game is implemented in accordance with the transmitted game progress information. A host game machine of the game machines transmits turn determination information to the other game machines, and receives turn completion information from each of the other game machines. When the turn confirmation information is not returned from one of the other game machines, the host game machine recognizes that communication has been cut off. When the communication has been cut off, the host game machine functions as a substitute for the cut off game machine.

The interchangeable lens includes a lens holding member holding a lens, a first supporting bar engaging with the lens holding member to guide movement of the lens holding member in an optical axis direction, a second supporting bar engaging with the lens holding member to prevent rotation of the lens holding member, the second supporting bar having a shorter length than that of the first supporting bar. The interchangeable lens further includes a mount contact provided as an electric contact in a mount portion detachably attachable to a camera body. When viewed from the optical axis direction, the first supporting bar is disposed in an area not overlapping the mount contact, and the second supporting bar is disposed in an area overlapping the mount contact, and when viewed from a direction orthogonal to the optical axis direction, part of the first supporting bar overlaps the mount contact.

Interchangeable lens

A lens unit includes an operating member to be operated by a user, an area configured to switch the operating member between an operable state and an inoperable state, and an urging member configured to urge the operation locking member toward the position at which the operating member is brought into the inoperable state.

Lens unit

A print managing server is connected to a plurality of printers through a network and stores print data which can be printed by the printer in combination with user information. The print managing server has control means for controlling execution of a command including the user information which is received from the printer. The control means controls in such a manner that when the command is received, if a printing process corresponding to the user information included in the command is being executed for the other printer, the printing process which is being executed is stopped for the other printer and a process corresponding to the command is executed.

An aluminum alloy thermal exchanger has an aluminum alloy metal surface without any harmful chromium ions and having good corrosion resistance and good hydrophilicity. The thermal exchanger includes an aluminum alloy metal having a surface provided with a first protective layer of chemical conversion coating produced by using a first treatment liquid, the first treatment liquid including a water soluble vanadium compound and a fluoro-zirconium complex compound. The first protective layer has a second protective layer of hydrophilic film thereon. The second protective layer is produced by adding and drying a second treatment liquid, the second treatment liquid including an aqueous polyvinyl alcohol polymer having a vinyl alcohol unit of more than 40% and another polymerization unit of less than 60 mol %, polyoxyethylene glycol having a weight average molecular weight of 6,000 and 1,000,000, a vanadium compound, and a zirconium compound, wherein, in the second treatment liquid, the ratio of the weight % of zirconium and vanadium is 40-350.
