Inventor: SIVERLING MICHAEL MCHUGH
IPC: G11B5/596
Filed: 1982-05-12
Abstract: The servo system includes the use of servo signals of four types such that each group of four adjoining servo tracks identifies the center line of a data track of interest and presents unique signals from the respective four servo tracks. The analog value of the signals are stored and sensed to provide a substantially linear position error signal over a three-track wide region. By using variable gain with respect to the analog signals, compensation for the variance between data head width and track pitch, and a quadrature servo portion, linearity can be achieved. In addition, since the substantially linear region is three tracks wide and the position error signal does not become ambiguous over , a width of four tracks, a one-track seek can be accomplished using an error signal rather than a seek.

During this rotation, approximately half of all the vessels (105) cross the light path of said photometer (103) for the absorbance of fluid in each vessel (105) to be measured. 
     A reagent is added to said specified reaction vessel (105) at the next stop position after sampling in order to start reaction. Said turntable (140) is again rotated and stopped so as to advance said reaction vessel (105) by half a revolution plus one cell. During this rotation, said reaction vessel (105) crosses said light path of said photometer (103) for the absorbance of said reaction fluid to be measured. Said reaction vessel (105) stops at the second reaction vessel position beyond the initial sample adding position. During the course of repeated rotations, said specified reaction vessel (105) crosses said light path of said photometer (103) a number of times and is stopped at said sample adding position after it is washed to be ready for further use.

Abstract: Metal-coated optical fibers are often employed in high temperature optical communications applications. However, such optical fibers have been found to evidence a substantial decrease in optical transmission as a function of increased temperature. Optical fibers having a temperature-insensitive optical transmission are obtained by annealing a metal-coated optical fiber at a temperature at which optical transmission is substantially the same as that observed at room temperature. Aluminium-coated optical fibers annealed at 560°C evidence an optical transmission independent of temperature between about -200°C and at least about 560°C.
