  • Publication number: 20070126837
    Abstract: A belt drive controller for controlling each belt stopping position with high accuracy during intermittent movement of a belt. This belt drive controller controls driving of a belt to intermittently move a belt wrapped around a plurality of supporting rollers including a driven roller and a drive roller. This controller detects a rotation angular displacement or a rotation angular velocity of two supporting rollers having mutually different diameters, and controls driving of the drive roller based on the detected rotation data so that the position of the belt in the direction of movement becomes a predetermined target position.

  • Publication number: 20070074076
    Abstract: A network fault diagnostic device is configured in the following manner. A causal relation table stores causal relations between faults and events, and a monitor event selector refers to the causal relation table to extract a minimum event required for identifying a fault, and sets the event as a monitor event. The acquisition-event selector selects events from the causal relation table based on latest fault candidates, and sets priorities of the events selected, in the order of efficiently identifying faults. The event acquiring unit requests events in the order of the priorities set, and the event receiving unit receives each event in response to the respective requests. The fault determining unit narrows down the candidates of the fault based on the events received one by one.

  • Publication number: 20070053081
    Abstract: The present invention provides a lens holder comprising a third group frame that serves as a holding member which holds lenses, a guide shaft that supports the third group frame when the third group frame is moved along the optical axis of the lenses, a rear barrel part perpendicularly to which the guide shaft is locked, a first bearing member that is molded as an integral part of the rear barrel part in order to bear the end of the guide shaft distal to the rear barrel part, and a guide shaft presser that when the first bearing member bears the end of the guide shaft distal to the base, bears the end of the guide shaft proximal to the rear barrel part. Moreover, the present invention provides a lens barrel and an imaging apparatus that employ the lens holder. Consequently, the structure of a bearing that bears a shaft which supports the lens holding member when the lens holding member is moved along the optical axis of the lenses is downsized. Moreover, the bearing bears the shaft highly precisely.

  • Patent number: 7028151
    Abstract: When an input address AD is previously stored in a register 211, if a matching signal EQ1 is active, then an address queue control circuit 19A latches an offset of the input address AD into a register 241, or else, latches the input address AD into a register 212 through a selector 262. When the input address AD is previously stored in the register 241, the address queue control circuit 19A latches the input address AD into the register 212 through the selector 262. After reading the contents of the register 211, the address queue control circuit 19A shifts the offset OFS of the register 241 to the offset field of the register 211 through a selector 261, and resets a valid flag EF of the register 241.
