摘要:
A strand guiding apparatus includes a plurality of pairs of rollers arranged along a moving direction of a strand, a plurality of drive motors for generating driving forces to drive the pairs of rollers, a plurality of worm reducers for transmitting the driving forces of the drive motors to the pairs of rollers while reducing the rotational speed of the drive motors, each worm reducer having a worm extending in a direction orthogonal to an axis of the corresponding roller, and operable to transmit a load occurring at the roller to the corresponding drive motor, and a control unit for controlling the respective rotational speeds of the rollers and/or the respective driving forces of the drive motors based on the load to the drive motors. The reliable control for drive rollers can be attained to have a proper rotational speed without causing a reduction in surface quality and chatter in a strand guiding apparatus for continuous casting equipment using worm reducers.

An engine control unit has a data memory for storing freeze frame data that is data indicating the operating status of vehicle equipment at the time when an abnormality of the vehicle equipment is detected. The engine control unit saves the freeze frame data stored in the data memory in a storage unit of a management station outside the vehicle through radio communication. The engine control unit determines the properness of the communication and performs a memory operation for erasing the relevant freeze frame data from the data memory based on a determination that the communication has been properly performed.

A system and method are provided for prior-constrained mean shift analysis of a data array, the system including a processor, an input adapter in signal communication with the processor for receiving at least one data array, and a prior constraints unit in signal communication with the processor for performing a prior-constrained mean shift analysis on the at least one data array; and the method including receiving initialization data, selecting an initial point relative to the initialization data, Gaussian fitting with a prior-constrained mean shift responsive to the initial point to parse a structure, and setting the parsed structure as a prior constraint.

A method for estimating a diameter of an object of interest, includes extracting a sub-volume of voxels around a marker identifying a location of the object of interest, and determining a segmentation result identifying an edge of the object of interest by a reactive-diffusion method. The method further includes performing a boundary check on the segmentation result to determine whether the object of interest is solitary, estimating a diameter of the object of interest from the segmentation result upon determining the object of interest to be solitary, and extracting the object of interest by performing ellipsoid fit on the sub-volume and estimating a diameter of the object of interest upon determining the object of interest to be non-solitary.
摘要:
A network system is formed with a parent station and programmable controllers and a programmable display devices serving as child stations connected to a single general-purpose serial communication circuit. Whichever child station received the token from the parent station outputs a command. Data are exchanged between the programmable display device and any of the programmable controllers by command-response communication. Data are exchanged among the programmable controllers by data link operations.
摘要:
A programmable controller has a multi-purpose processor such as an MPU and an application specific control device such as an ASIC (application specific integrated circuit). When the MPU requests the ASIC to execute a user program and the ASIC is activated, the MPU executes an event process while the ASIC executes the requested user program. When the MPU requests the ASIC to execute a DMA transfer process in an input/output refresh process and the ASIC is activated, the MPU executes an event process while the ASIC executes the requested DMA transfer process.

A metal structure according to the present invention is unlikely to become brittle and has excellent hardness and creep resistance, characterized in that annealing has been applied at a temperature not more than the temperature at which crystals of the metal material start to become larger. This metal structure includes at least two kinds of metal material, and annealing can be applied at a temperature not more than the temperature at which crystals of the metal material start to become larger. For example, the present invention is advantageous in the manner of a microstructure for a contact probe. A fabricating method according to the present invention is a method of fabricating a metal structure unlikely to become brittle and having excellent hardness and creep resistance, characterized in that the step of applying annealing at at a temperature not more than the temperature at which crystals of the metal material start to become larger is included.
