Publication number: 20080148249Abstract: A system and method for setting a software option of a numeric control device, by which a user cannot set the options without permission and a cost regarding option configuration may be recovered by a maker. A maker PC generates option setting data for setting bit information to one or zero, based on a name or a number of a software option to be set, in order to make the function of the software option valid or invalid. This data is encoded or encrypted by using a unique identification number of a control device. The control device reads and decodes the encoded software option setting data, in order to set data of the corresponding memory address and bit number in the control device to one or zero. By using the unique identification number of the control device, only the control device, the software option setting data of which is required, can decode the encoded data.Type: ApplicationFiled: December 11, 2007Publication date: June 19, 2008Applicant: FANUC LTDInventors: Hidetsugu KOMIYA, Yasushi ISHIKAWA, Naoki FUJITA, Akira YAMADA, Hiroshi IMAI

Patent number: 7111121Abstract: A USB storage device having the function of preventing stored software from being deleted by mistake achieved with as simple a structure as possible. In the USB storage device, the storage area is divided into an area in which execution of reading, writing and deleting is allowed and an area in which only execution of reading is allowed. Information to make a USB mass storage class driver recognize these areas as areas corresponding, respectively, to logical unit numbers defined in the SCSI command set of the USB mass storage class driver owned by the host is stored in the USB storage device. The information includes logical unit numbers, formats, writing/deleting allowed/not allowed flag, logical block numbers and physical block numbers. By this, the USB mass storage class driver recognizes the USB storage device as a SCSI device having two logical units.Type: GrantFiled: May 28, 2003Date of Patent: September 19, 2006Assignee: Hagiwara Sys-Com Co., Ltd.Inventors: Yuji Oishi, Kimitoshi Nakamura, Megumi Tokunaga, Kaoru Miyazaki, Kaihei Ito, Naoki Fujita

Patent number: 6820179Abstract: A semiconductor device which has an internal circuit for performing a circuit operation corresponding to a signal inputted or outputted through an input/output interface circuit adapted to a serial bus. The semiconductor device has a non-volatile storage circuit for storing identification data. Internal identification data stored in the non-volatile storage circuit is compared with external identification data included in an input signal supplied through the serial bus by a comparator circuit. A control circuit is responsive to a match detecting signal generated by the comparator circuit to perform a circuit operation corresponding to an input signal subsequently supplied through the serial bus to change the internal identification data stored in the non-volatile storage circuit.Type: GrantFiled: December 4, 2001Date of Patent: November 16, 2004Assignees: Hitachi Hokkai Semiconductor, Ltd., Renesas Technology CorporationInventors: Nobuharu Kobayashi, Masanobu Kawamura, Toru Ishida, Masato Momii, Naoki Fujita
