Patent number: 9315010Abstract: In a thermal stencil-making machine, a thermosensitive stencil screen made by pasting a thermo sensitive material on a stencil-making side of a mesh screen for screen printing and a thermal perforator that perforates the thermosensitive stencil screen are relatively moved to each other to thermally perforate the thermosensitive material according to image information. The thermal stencil-making machine includes a residue remover that removes a melted residue generated on the stencil-making side of the thermosensitive stencil screen along a circumference of a perforated hole when the thermosensitive material is melted by the thermal perforator. The residue remover removes the melted residue while the thermosensitive stencil screen and the thermal perforator are relatively moved to each other.Type: GrantFiled: August 17, 2015Date of Patent: April 19, 2016Assignee: RISO KAGAKU CORPORATIONInventor: Koki Mitani

Patent number: 8848912Abstract: A terminal identification method is provided which enables two-way communications between terminals and a network while identifying terminal IDs and protecting privacy. Also, authentication method and system are provided which require no complicated calculating process, less steps and smaller amount for wireless communications, and less power consumption. A server and terminal share a hash function and an initial value determined for each terminal, calculate the same temporary ID by hashing the initial value the same number of times with the hash function, and identify the terminal using the calculated temporary ID. The server and the terminal also hold a common hash function and authentication information, acquire an authenticating communication parameter from communication parameters temporarily common during communication, and generate an authentication key using the authentication information, the authenticating communication parameter, and the hash function.Type: GrantFiled: December 19, 2006Date of Patent: September 30, 2014Assignee: Nippon Telegraph and Telephone CorporationInventors: Koichi Takasugi, Koki Mitani, Hiroshi Saito
