Patent number: 7466300Abstract: The invention provides a display apparatus having a temperature sensor and a step-up circuit generating a drive voltage of the display apparatus by stepping up a power source voltage. The temperature sensor provides temperature data indicative of the temperature of the display panel with a reduced measurement error without limiting the operation of the step-up circuit. To do so, in view of the fact that the step-up circuit has alternating active state in which the circuit is stepping up a source voltage to output a required step-up voltage and inactive state in which no stepping operation is made, the temperature sensor is adapted to obtain temperature data while the step-up circuit is inactive. The temperature data obtained is supplied to a temperature compensation means for changing the drive condition setting value that define the drive condition of the display panel to compensate for the temperature change.Type: GrantFiled: February 17, 2006Date of Patent: December 16, 2008Assignee: Rohm Co., Ltd.Inventors: Takashi Naiki, Haruo Taguchi

Patent number: 6747546Abstract: An IC card 3 has an ID number ID0, for permitting itself to be identified, stored in memory provided therein. The IC card also has additional ID numbers ID1 to IDn stored in memory areas 17-1 to 17-n that are secured therein so as to be allocated to the individual providers that manage the reader/writers with which the IC card communicates. These additional ID numbers ID1 to IDn are used to prevent unauthorized use of the IC card, and are issued so as to be unique to the IC card by the individual providers that use the memory areas 17-1 to 17-n. Thus, the additional ID numbers ID1 to IDn differ from one IC card to another.Type: GrantFiled: February 25, 2000Date of Patent: June 8, 2004Assignee: Rohm Co., Ltd.Inventors: Junichi Hikita, Haruo Taguchi, Yoshihiro Ikefuji
