Patent number: 7609605Abstract: An optical read/write apparatus causes a read/write light beam from illuminating means to strike only one side of an optical storage medium including stacked data storage layers each of which is readable/writeable separately from the other layers. In this case, the optical read/write apparatus operates so that data is read/written from/into a second data storage layer after fully recording a recordable area of a first data storage layer. Thus, light can be shone with uniform intensity across the substantially entire recordable area of the second data storage layer without using a complex read/write system even under such conditions that the transmittance to light of the first data storage layer in the recordable area may vary depending on whether any data is recorded in the recordable area.Type: GrantFiled: February 2, 2007Date of Patent: October 27, 2009Assignee: Sharp Kabushiki KaishaInventors: Junji Hirokane, Noboru Iwata

Patent number: 7609984Abstract: The fixing device includes a pair of rotating bodies which conveys a recording medium between a nip; a heating unit which heats at least one of the rotating bodies; and a temperature detection unit which detects a temperature of at least one of the rotating bodies. The temperature detection unit detects a temperature change until an image forming apparatus is normally operated since the heating unit starts the heating, and the temperature change is stored. It is judged that the image forming apparatus is in an abnormal state when the temperature detection unit detects a temperature change different from the temperature change in the normal operation. A temperature control unit stops passage of current through the heating unit when it is judged that the image forming apparatus is in the abnormal state.Type: GrantFiled: January 19, 2007Date of Patent: October 27, 2009Assignee: Sharp Kabushiki KaishaInventors: Kohji Aoki, Toyoaki Nanba, Yoshinobu Tateishi, Yasuhiro Takai

Patent number: 7610411Abstract: There is provided a mediation section (34) for switching between an active status in which data transmitted to a specific address is registered and processed and a non-active status other than the active status. When the mediation section (34) judges that unprocessed data stored in a data storage section (31) cannot be processed in a predetermined time, the mediation section (34) instructs one or more other MFPs to change into the active status and causes the MFP including the mediation section (34) to change into the non-active status, so as to cause a data processing section (32) to process the unprocessed data. As a result, it is possible to perform mediation concerning a job (data) without using a server.Type: GrantFiled: June 22, 2004Date of Patent: October 27, 2009Assignee: Sharp Kabushiki KaishaInventors: Atsushi Umekage, Suehiro Ueda, Hiroshi Takatani

Patent number: 7609837Abstract: A system and method for use with local area networks (LANs) automatically configures a new device on a LAN by secure encrypted transmission of setup parameters. A remote control (RC) with an infrared (IR) transmitter contains a stored setup command and a security number that is used only once (a “nonce”). Setup of a new device is initiated by pressing a “setup” button on the RC which generates the security number and transmits it and the setup command to the new device via IR. The new device receives the setup command and security number and queries the network for the setup parameters. The RC also transmits the security number via IR to a network member device that contains the setup parameters. The network member uses the security number as an encryption key to encrypt the setup parameters and transmit them over the network. The new device uses the security number as the decryption key to decrypt the transmitted setup parameters.Type: GrantFiled: September 1, 2005Date of Patent: October 27, 2009Assignee: Sharp Laboratories of America, Inc.Inventor: Richard T.
