Abstract: SYSTEM FOR OBTAINING OPTIMUM FOCUSING POSITION              IN OPTICAL DISC SYSTEM                ABSTRACT OF THE DISCLOSURE       A system for obtaining an optimum focusing position in an optical disc system, wherein an optical beam is impinged onto a track of an optical disc, and a reflection signal having information of an intensity of a optical beam reflected by an optical disc, is obtained. A predetermined frequency component, which component is generated by a modulation caused by an ex-istence of a pit on a track of the optical disc in a reflecting signal, is extracted from the reflection signal, and then a focus position wherein a maximum intensity of the above extracted component is obtained, is searched by changing the focus position of the optical beam. Further, the above system is incorporated in a focus servo control system for maintaining an optimum focusing position in an optical disc system during reading and writing operations, to determine an optimum offset value which is to be adjusted to compensate an error arisen from a construction of the focus servo control system, during an offset adjusting operation.

Abstract: A remote  sensing  tonometric  catheter  apparatus  (20)  and method for sampling of a fluid or gas property of interest in a hollow internal organ.  The tonometric catheter (20)  assists in early  detection  of  the  problems  of  stress  ulceration  and/or intestinal ischemia.  The tonometric catheter (20)  has one or more  sampling  chambers  (40)   for  introduction  into  a  hollow internal  organ  or  an  area  adjacent  thereto.   The  tonometric catheter (20) has an electric sensor (42)  for developing a signal indicative of the condition of the organ.  Electric sensor (42) is in communication with the sampling chamber (40).  The sensor (42)  has a conductor  (56)  coupled therewith for conveying the signal to a location outside the organ such that the condition of the organ may be remotely determined.  Preferably, the wall (36) of the sampling chamber (40)  is freely permeable to the gas or fluid to be measured by the sensor (42), but is poorly permeable to other gases or fluids which may interfere with the sensor (42).   The method is accomplished by introducing the catheter into the organ such that the sampling chamber is disposed at a portion of the wall of the organ.  The sampling chamber is left in position at the wall of the organ for a time sufficient to allow the fluid or gas of interest to diffuse into the sampling chamber.  The concentration of the fluid or gas of interest is analyzed.  The pH of the wall of the organ may be calculated based  on  the  concentration  of  the  fluid or  gas  property of interest.

Abstract: Video is applied via a gain controlled IF amplifier (11) to a video detector (13) and amplifier (15). Sync and equalising pulses are fed from the amplifier to an active filter (21-26) and then to a comparator (30), which produces an output variation for changing an AGC voltage produced by generator (40) and AGC capacitor (41) if the pulse peaks exceed a threshold. The filter (21-26) delays and attenuated noise impulses, but can also cause noise impulses to remain above the threshold for a period of time defined by pulse stretching in the filter. A transistor (32) is responsive to a potential difference of predetermined sense and magnitude between the input and output of the filter to curtail the output variation of the comparator (30). Such a difference exists when a delayed leading edge of a noise pulse is present at the output of the filter and the trailing edge is at the input.

Abstract: A multi-layer through-hole contacted flexible circuit board and method of manufacture thereof is presented having a laminar construction which is strictly symmetrical in the bending area; and which have no exposed adhesive. Registration holes are first introduced in a copper-laminated base material, then, avoiding the bending area, with the aid of the registration holes, an adhesive layer is applied to the non-conductive film carrier of the base material. Next, a second copper foil is placed on the adhesive layer. Thereafter, all of the layers are laminated. This is followed by the formation of through-holes in the area surrounding the bending area while circuit patterns are formed in the flexible or bending area (the registration holes again providing assistance in positioning). The spaces between the circuit pattern, as well as the entire copper foil, is then etched away in the bending area, and, finally, all the conducting path areas are covered with non-conductive cover film. As a result, the conducting paths are located in the "neutral section", that is, the area of the flexible circuit board which is neutral with respect to the forces generated during bending.
