Abstract: The invention describes a method for determining the spectral or spatial distribution of nuclear magnetisation in a limited volume range. In this arrangement, four high-frequency pulses act on the area of investigation in the presence of a homogeneous stationary magnetic field, the last two of which pulses and one of the first two being layer-selective and the second high-frequency pulse being a 180 DEG pulse. This makes it possible to use nuclear magnetisation in the area of intersection of the layers excited by the three high-frequency pulses for generating an FID signal or a spin echo signal. <IMAGE>

Abstract: A mechanical pencil (10) for a plotter, and lead advance methods for use with a mechanical pencil employed in such plotters. A mechanical pencil (10) is modified and adapted for use in an existing plotter. The modified pencil (10) applies 100% of the available down force provided by the plotter on the pencil lead (14). A pencil body (11) adapted for use with the plotter is provided, along with a knocking disk (17) and tube (16) arrangement located at the top end of the pencil (10) for advancing of the lead (14). A different embodiment of the pencil (10) permits the use of small diameter lead (14). This is accomplished by the use of an improved floating collar (40) comprising a small diameter tube (42) within the collar (40) that supports the small diameter lead (14) during writing operations. This arrangement prevents side loading of the collar (10), and hence minimizes lead breakage. A spring-loaded collet arrangement (25-39) is disposed in the lower portion of the pencil body (11) and is employed to advance the lead (14) in response to operation of the knocking disk (17) and tube (16) arrangement. In the preferred lead advance method, a vertical axis encoder sensor is used to measure the length of lead in the pencil (10). If the lead (14) length falls below a predetermined threshold, the plotting operation currently in progress is suspended and the lead (14) in the pencil is advanced. After the lead-advancing operation has been satisfactorily concluded, the plotting operation is resumed at the point at which it was interrupted. In a second method, a different lead advance algorithm employing a variety of lead advance routines monitors and controls the lead dispensing process. The algorithm employs six routines which allow the algorithm to accurately predict and control future lead usage.

Fluoroscopic indicating stripes (39, 41) may be provided at the distal end (23) of the sphincterotome (21). A method of use and method of fabrication of the present invention is also disclosed.

Abstract: A method for operating a digital signal processor (34) in a focus servo system of an optical disk drive (10) to obtain focus capture. During a calibration subroutine (90), the servo system is operated in an open-­loop mode and the processor (34) generates focus drive signals causing an objective lens (20) to be driven about a focus axis (54) at a calibration velocity. Focus error signals produced while the objective lens (20) is driven at the calibration velocity are peak detected to determine a peak focus error signal. A calibration threshold value generated as a function of the peak focus error signal is stored in memory. After the calibration routine, the processor (34) executes a focus capture subroutine (94) to bring the objective lens (20) within focus capture distance of the optical disk (12). The processor (34) generates focus drive signals causing the objective lens (20) to be driven about the focus axis (54) at a focus capture velocity which is less than the calibration velocity. Focus error signals produced while the lens (20) is being driven at the focus capture velocity are compared to the calibration threshold value. When the focus error signals reach the calibration threshold value, the digital signal processor (34) generates focus drive signals causing the objective lens (20) to accelerate for a predetermined time period. The servo loop is then closed and the focus servo system operated in the closed-loop mode.
