Patent number: 10632526Abstract: The primary object of the present invention is to provide a mold for continuous casting including a temperature detection unit which can detect the temperature of a copper plate of the mold with high precision, and can be easily inserted into and pulled out of the copper plate. The present invention includes: a main body; and a temperature detection unit which is inserted in an insertion hole in the main body, and detects temperature inside the mold. The temperature detection unit includes: an FBG sensor inserted in a protection tube which can be deformed in a radial direction; and a support member which supports the FBG sensor along the longitudinal direction. At a temperature detection point, the protection tube in which the FBG sensor is inserted is held between a stretched member in the support member and an inner surface of the insertion hole.Type: GrantFiled: April 8, 2016Date of Patent: April 28, 2020Assignee: NIPPON STEEL CORPORATIONInventors: Tatsuro Honda, Nozomu Yoshihiro, Shinichi Fukunaga, Takeshi Okawa

Patent number: 8090960Abstract: At a seller, an encryption device encrypts content data stored in a content server using an encryption key generated by an encryption key generation device, and records the encrypted content data and a communication program on a recording medium. A paper indicating an identification code unique to each recording medium is attached to the recording medium. A decryption key corresponding to the encryption key and the identification code are registered in a managing database. A user terminal sends the identification code to a decryption key managing server apparatus via Internet in accordance with the communication program, in a case where the user terminal is to copy or install or reproduce the content data stored on the recording medium. The decryption key managing server apparatus sends a decryption key corresponding to this identification code to the user terminal. The user terminal decrypts the content data using the decryption key sent thereto.Type: GrantFiled: July 27, 2006Date of Patent: January 3, 2012Assignee: Ricoh Company, Ltd.Inventor: Takeshi Okawa

Publication number: 20070233548Abstract: Visitor support database stores information on visitors and staff members in charge of visitors. Visitor support server receives information on visitor from reception device and specifies staff member in charge of him/her. Server extracts information describing the visitor from the information on the visitor, generates correspondence message, and sends it to a staff member terminal. Booth terminal specifies visitors in a booth based on reception information and information on visitors stored in database, and determines whether the visitors have an inclination. When the visitors have an inclination, booth terminal performs a demo to be performed at the booth according to this inclination. Database stores information on handouts distributed at booths, and booth entry information.Type: ApplicationFiled: March 15, 2007Publication date: October 4, 2007Inventor: Takeshi Okawa
