  • Patent number: 7560975
    Abstract: The well voltage of a CMOS circuit having low-threshold-voltage MOSFETs is controlled when the power supply is turned on, during normal operation, and when the supply voltage is cut off. The CMOS circuit can thus operate stably with lower power consumption, because latching-up is reduced when the supply voltage is applied to the CMOS circuit or when the supply voltage is cut off, and subthreshold current is decreased during normal operation.

  • Patent number: 7558323
    Abstract: In a picture transmission network including networks of different transmission speeds, when a picture is sent at a bit rate which is adjusted to the transmission speed of a low-speed network, only a low-quality picture of a low bit rate is obtained in a video reception unit connected to a network of a high transmission speed. When a picture is sent at a transmission rate of a network having high transmission speed, the picture cannot be reproduced at all in a video reception unit connected to a network of a low transmission speed. To solve the problem, a video transmission unit generates at least an I picture data and a plurality of P picture data. In accordance with a request from the network, the I picture data and a predetermined number of P picture data is transmitted to the network.

  • Patent number: 7526747
    Abstract: Secondary electrons and back scattered electrons generated by irradiating a wafer to be inspected such as a semiconductor wafer with a charged particle beam are detected by a detector. A signal proportional to the number of detected electrons is generated, and an inspection image is formed on the basis of the signal. On the other hand, in consideration of a current value and irradiation energy of a charged particle beam, an electric field on the surface of the inspection wafer, emission efficiency of the secondary electrons and back scattered electrons, and the like, an electric resistance and an electric capacitance are determined so as to coincide with those in the inspection image. In a state where a difference between a resistance value in a normal portion and a resistance value in a defective portion is sufficiently increased by using the charging generated by the irradiation of electron beams, an inspection is conducted to thereby detect a defect.

  • Patent number: 7526668
    Abstract: By incorporating a referral mechanism, a failover method and system for remotely mirrored clustered file servers enables a client computer to transparently access a remotely mirrored file system during a failover of a first NAS (network attached storage) storing the file system. The first NAS is clustered with a second NAS that takes over the IP address of the first NAS on failover. A mirroring relationship is established between the first NAS and a third NAS whereby a copy of the file system is replicated to the third NAS. A referral is created on the second NAS, such that an access attempt from the client computer for accessing the first file system that is directed to the second NAS following IP address takeover from the first NAS after failover is referred to the third NAS by the referral to enable the client computer to access the copy of the file system.
