Abstract: This optical disk device includes a read means which reads data from an optical disk upon which data is recorded at a variable bit rate for each sector. Moreover, this optical disk device includes a buffer memory which sequentially stores data which has been read by the read means, and a replay means which sequentially reads out and decodes data stored in the buffer memory, and replays that data. Furthermore, this optical disk device includes a control means which, when a command for special replay is issued, calculates the address of the sector currently being decoded by the replay means based upon the address of the sector currently being read by the read means, and upon the amount of data stored in the buffer memory. And the control means commands the read means to read out, from the optical disk, a sector to be jumped to.

Abstract: A method of preparing a gassed water-in-oil emulsion explosives composition from a gasser solution of an inorganic nitrate, an ammonium species and an optional accelerator which is added to an emulsion explosive composition, reacts and forms gas bubbles is disclosed. The emulsion explosive composition is composed of a discontinuous aqueous phase, a continuous water immiscible organic phase, and an emulsifier. The reaction between the gasser solution and the emulsion explosive composition is such that the emulsifier does not undergo chemical attack.

Abstract: One embodiment of the present invention is a method for automatically controlling the conversion of a tiltrotor aircraft. An airspeed command for the tiltrotor aircraft is received. The airspeed command is converted to a pylon position. A difference between the airspeed command and a measured airspeed is calculated. The difference between the airspeed command and a measured airspeed is converted to a dynamic pylon position. A total pylon position is calculated from the pylon position and the dynamic pylon position. A pylon of the tiltrotor aircraft is moved to the total pylon position. Another embodiment of the present invention is a system for calculating a position of a pylon of a tiltrotor aircraft based on an airspeed command. The system includes an airspeed command module, a pylon trim position module, a dynamic pylon position module, and a pylon position module.

Abstract: An object lens driving device comprises a movable unit which supports an object lens and is movably supported by a fixed unit, a first mechanism which has a first magnet affixed to a fixed unit and a first coil affixed to a movable unit, and drives the movable unit in a predetermined direction by supplying electricity to the first coil, and a second mechanism which has a second coil affixed to a fixed unit and a second magnet affixed to a movable unit, and drives the movable unit in a direction different from that of the first mechanism by supplying electricity to the second coil, wherein the first and second magnets are arranged so that their polarities have the same orientation.
