摘要:
A digital convergence apparatus using two different kinds of data to correct the convergence of odd and even scanning lines, respectively. A first memory stores data for the convergence correction corresponding to plural correction executing points aligned in the horizontal or vertical direction of a screen. A first static convergence data memory stores a first static convergence correction data for correcting the entire screen in the same direction, a second static convergence data memory stores a second static convergence correction data different from the first static convergence correction data only by an amount corresponding to the distance between the scanning lines. Selecting means select the output of the first or the second static convergence data memory according to the odd field period or the even field period. Adding means add the output of the selecting means to the data stored in the first memory. Vertical interpolating means interpolate the output of the adding means in the vertical direction, and a convergence correction coil corrects the convergence based on the output of the adding means.

NTSC convergence adjusting data corresponding to a plurality of portions on a display screen is stored in a data storage section in advance. Convergence adjusting data is stored in a field memory in a NTSC scanning mode. Adjusting data transferred to the memory is supplied to a vertical interpolation circuit, and interpolation adjusting data between the adjusting points is created using the plurality of adjusting data and interpolation coefficients. Data output from the vertical interpolation circuit is A/D-converted, and supplied to a deflection coil through a low pass filter as a convergence correction signal. In a PAL scanning mode, PAL convergence adjusting data is created with use of NTSC convergence adjusting data by a control microcomputer so as to be stored in the frame memory.
摘要:
A field memory stores convergence adjusting data which corresponds to a plurality of points on a display screen. An interpolation calculation circuit creates interpolation convergence adjusting data for correction points located between adjacent adjusting points, using a plurality of adjusting data items and interpolation coefficients. The output of the interpolation calculation circuit is subjected to digital/analog conversion and passed through a low-pass filter, thereby forming a convergence correction signal. This correction signal is supplied to each deflection coil. At the time of creating interpolation adjusting data for a point located between adjusting points, an optimal interpolation coefficient is output from a ROM or a ROM, depending upon whether the point is included in the odd or even field.

An object of the present invention is to provide the exhaust treatment device of a diesel engine which is capable of prohibiting the execution of DPF regenerating processing in a situation in which the DPF regenerating processing is inappropriate. In order to achieve the object, DPF regenerating mode switch manipulation means (7a) switches a DPF regenerating mode to a normal and acceleration coexistence regenerating mode (51) or an acceleration-sole regenerating mode (52), and DPF regenerating selection manipulation means (7b) switches a position to a normal regenerating permission position (53), a normal regenerating cancel position (54), or an acceleration regenerating execution position (55). When the DPF regenerating mode is in the acceleration-sole regenerating mode (52), the DPF regenerating control means prohibits normal regenerating processing by the DPF regenerating means irrespective of a position selected by the DPF regenerating selection manipulation means (7b).

A mobile communication terminal 10A, in a process of acquiring assistance information in advance for using for a GPS position measuring at step S10, makes a judgment of whether or not the assistance information is to be acquired, prior to the GPS position measuring command by a user. When a result of this judgment is affirmative, the terminal 10A transmits an assistance information request to a position measuring assistance server 50. When the assistance information is returned from the position measuring assistance server 50 in response to this the assistance information request, in the cellular phone 10A, the assistance information is received and stored, and then prepared for a command for position measuring by the user, for which possibility of being made is higher in a short period. As a result, it is possible to perform quickly the position measuring of a current location of the mobile communication terminal.

摘要:
An edging mill for section rolling has a pair of horizontal rolls, each horizontal roll including a pair of axially spaced horizontal roll segments supported by driven horizontal roll shafts. Eccentric rings are disposed between the two horizontal roll segments making up each horizontal roll and are rotatably mounted on the horizontal roll shaft. The eccentric rings are eccentric to the horizontal rolls. Web-restraining ring rolls each comprise a pair of web-restraining roll segments rotatably fitted over the periphery of the eccentric rings concentrically thereto. A web-restraining ring roll positioning device rotates the eccentric rings. While the horizontal rolls roll the flange edges of the section, the web-restraining ring rolls hold the web of the section therebetween. The position of the web-restraining ring rolls with respect to the horizontal rolls changes with the rotating angle of the eccentric rings. The position of the web-restraining ring rolls is adjusted according to the flange thickness of the section.
