20100087966 | Physical quantity measuring apparatus - The physical quantity measuring apparatus includes a first function of generating voltage used for position-controlling a movable body, a second function of detecting a position of the movable body during a position detecting period, a third function of calculating a control amount necessary to keep the movable body at a predetermined position on the basis of a detection result by the second function, and causing the first function to generate a control voltage corresponding to the calculated control amount to keep the movable body at the predetermined position during a position controlling period, and a fourth function of setting the position detecting period and the position controlling period in a time-sharing manner so that the position detecting period and the position controlling period do not overlap with each other. | 04-08-2010 |
20100237923 | Method of placing delay units of pulse delay circuit on programmable logic device - A method of placing delay units of a pulse delay circuit on a programmable logic device having logic cells in each of cell strings has a step of arranging each delay unit in one logic cell of the device such that the delay units are placed in respective specific cell strings aligned in a row direction and a step of serially connecting the delay units with one another as a straight delay line such that the delay units placed in the specific cell strings in the connecting order are aligned in the row direction. In the device, an inter-string transmission delay time on a line between two logic cells of different cell strings differs from an intra-string transmission delay time on a line between two logic cells of one cell string. | 09-23-2010 |
